NBC Presents A World Without Electricity on Revolution


What would a world without electricity look like? That's a question that Hollywood's J.J. Abrams is attempting to answer this Fall on NBC in a new hour-long Science Fiction drama called Revolution. Set 15 years after the world's electricity mysteriously blinks out, the show premieres tonight at 10:00 p.m. U.S. EDT/9:00 p.m. U.S. CDT on the peacock network.

The full premiere episode is available as a free preview on iTunes, so I was able to catch it over the weekend. While I wouldn't want to reveal any spoilers, I'll just say that a lot of the program looks awfully familiar. If you've ever watched Life After People on cable's History Channel, you'll know exactly what I mean. But while the world the characters inhabit looks a lot like post-apocalyptic worlds we've seen on television and in the movies before, it sure seems like more than a few folks managed to stash a working blow dryer and a washing machine somewhere.

Then again, this is network television, and suspension of disbelief is always a prerequisite. That being said, I'll have the DVR to set record episode #2 next Monday night.

Japan to Phase Out Nuclear Energy – Over 30 Years – Maybe

The New York Times has the story:

In its first comprehensive energy review since the Fukushima disaster, Japan said on Friday that it would seek to phase out nuclear power by the end of the 2030s — but only after a longer-than-expected transition that would give power companies decades to recoup their investments and brace for a nonnuclear future.

By the end of the 2030s? The Times also notes this:

In announcing the plan, however, Motohisa Furukawa, the minister of state for national policy, seemed to suggest that the measures were loose guidelines open to revision and discussion. For example, he said the government would leave to future discussion whether five reactors that would be younger than 40 years by the end of the 2030s would be forced to close — leaving open the possibility that some reactors will remain running into the 2040s and beyond.

I wondered how Prime Minister Yoshihiko Noda was going to thread the needle between bowing to the will of the people and the need to keep the economy from cratering – and I guess this is it.

The Times has decided this will satisfy business owners but not other factions:

“It’s trickery with words and numbers,” said Tetsunari Iida, director of the Institute for Sustainable Energy Policies, a research group based in Tokyo. “The zero number might be symbolic politically, but in reality, it holds little meaning.”

“How is the government going to push through reactor restarts when there’s still so much opposition? It has no clue what to do next month, never mind by the 2030s,” he said.

I’d guess Iida is a renewables guy, so factor that in.

---

There is a risk of sounding too much like Goldilocks about this news – if Germany is shuttering its plants too quickly and Japan too slowly, what’s just right?

Let me leave aside the obvious answer – don’t shut the plants down – and say, as I’ve said numerous times before, that nuclear energy is not a trap. Countries have to decide their energy profiles for themselves. Investing heavily in any energy source and then leaving it – especially when it is inexpensive and a potent supplier – is going to generate numerous economic and social issues that have to be addressed. The Japanese are explicit in saying that it doesn’t want to crater its power companies:

The 2039 time frame, on the other hand, would allow most of those reactors to live out their 40-year life span, heading off costly losses for their operators. Japanese utilities are also saddled with the huge costs of buying oil and natural gas to meet the nuclear shortfall, a burden that would be alleviated once their reactors are restarted.

So Japan has made a decision that sidesteps many of the obvious issues surrounding such a decision; it has kicked the can way, way down the road. The only conclusion I can really draw is that the story of nuclear energy in Japan is far from over.

---

A word of warning. The Asahi Shimbun (a national Japanese newspaper) and other Japanese outlets offer accounts of a meeting between Japanese officials and U.S. Deputy Energy Secretary Daniel Poneman about the long nuclear exit, but I couldn’t find an American source about this. That’s a red flag – not because the Japanese reports are inflammatory or even wrong necessarily, but you want to be careful about stories in translation. (The absence of it in the Times story is another reason for caution.)

There’s also some talk in the stories about the Japanese hording coal and natural gas and causing higher energy prices worldwide. This is highly dubious at worst, idle speculation at best.

In other words, some of the reporting is less than it should be, so keep the truthiness radar on.

NEI Energy Markets Report (September 3-7, 2012)

Here's a snippet of what went on in the energy markets last week:

Electricity peak prices were mixed last week across the country. ERCOT-Houston and PJM West hubs saw the most action, rising $20 and $12 to average around $55/MWh, respectively. Prices at the Western, Northeastern and Southeastern hubs remained soft, moving less than $5/MWh in either direction. “Power prices across the United States moved mostly higher Tuesday, Sept. 4, with the largest gains recorded in parts of the East and Midwest after markets were closed Monday for Labor Day. … PJM West jumped more than $10 on the day with trades in the mid- to upper $50s, driven in part by a higher demand forecast as the PJM grid operator expects demand in the Western region reaching 69,700 MW on Wednesday. … As the Gulf Coast recovers from Hurricane Isaac's landfall last week, hotter weather and higher demand helped push ERCOT power prices higher Tuesday” (SNL Energy’s Power Daily – 9/5/12).

Average nuclear plant availability remained at 90 percent last week. After brief outages, Palisades, Three Mile Island 1, Turkey Point 3, Watts Bar 1, and Waterford 3 returned to service. Dresden 2 closed for five days to “perform maintenance work on water tubes in the unit's condenser.” Limerick 1 closed for four days for inspections, repair and testing of its low-pressure turbine blades.

No Need to Fret About UT-Austin's TRIGA Reactor, No Matter What Drudge Might Point To

A Mark II TRIGA reactor at KSU.
A lot of folks around the country are dealing with jangled nerves after the campuses at UT-Austin and North Dakota State were evacuated in the wake of vague threats of terrorist attack. Thankfully, the threats appear to have been a hoax.

When news breaks, the number one guy on the Web who wants to influence where the clicks go is Matt Drudge, chief cook and bottle washer at the Drudge Report. If you pop over to Drudge right now, you'll see all the screaming headlines, with just one in particular catching my eye:

Nuke Reactor Evacuated in Austin...

The first thing to keep in mind is that the reactor in Austin is on campus at UT, and it's a TRIGA Mark II Research Reactor that was constructed by General Atomics. The reactor was designed to be, in the words of Frederic de Hoffman, "safe even in the hands of a young student." The TRIGA Mark II generally operates between just 0.1 to 16 MWTh. By way of comparison, the average commercial nuclear reactor clocks in at about 1,000 MWe.

Some of our readers might recall how ABC News attempted to generate a cloud of FUD over the potential for terrorists to penetrate the security around research reactors, reasoning that the nuclear fuel could be removed to construct a dirty bomb, even though there isn't anywhere near enough fuel in the reactor to make that happen.

In other words, there's nothing to see here, though I'm sure Mr. Drudge's advertisers are happy that you stopped by.

UPDATE: I just got a short note from NEI Nuclear Notes reader, Art Wharton:

UT had its first TRIGA Mark I reactor in the basement of Taylor Hall(commissioned in the 60's), on main campus. It was decommissioned when the TRIGA Mark II reactor was built up on the JJ Pickle Research Campus ~ 10-15 miles north of main campus. Critical in 1992, it is the newest of all University reactors in the USA, including digital controls and a nice flat-screen display of the rod positions, proudly displaying a Longhorn logo background.

Fusion-Fission Fandango in Texas

Super Divertor XIt’s like the doublemint twins at the University of Texas at Austin.

The researchers — Mike Kotschenreuther, Prashant Valanju and Swadesh Mahajan of the College of Natural Sciences — have patented the concept for a novel fusion-fission hybrid nuclear reactor that would use nuclear fusion and fission together to incinerate nuclear waste. Fusion produces energy by fusing atomic nuclei, and fission produces energy by splitting atomic nuclei.

How does it work?

The researchers’ patent covers a tokamak device, which uses magnetic fields to produce fusion reactions. The patented tokamak is surrounded by an area that would house a nuclear waste fuel source and waste by-products of the nuclear fuel cycle. The device is driven by a transformational technology called the Super X Divertor.

The Super X Divertor is a crucial technology that has the capacity to safely divert the enormous amounts of heat out of the reactor core to keep the reactor producing energy.

I guess this means – well, I’m not sure what it means. It sounds as though the fuel rods would need to find their way to the tokamak via the Super X Divertor or perhaps the system would use something other than a fuel rod. Or I’m all wet. Let’s look for more detail.

---

This illustration (also above – click for larger) suggests a two part process – a fission/fission-fusion fandango - with light water reactors operating as they normally do, and the used fuel then further processed in the fission-fusion reactor.

This second reactor can also produce energy and presumably can be rated much as fission reactors are now done, so the result will be more electricity and perhaps a good deal of process heat, which theoretically has impressive industrial applications. Perhaps the use of the Super X Divertor, which diverts the heat so as to avoid it melting the containment, gives that use added plausibility.

This article provides a few more details. I admit I’m still lost on some elements of it; for example, what would seed the fusion reaction? ITER is using deuterium (heavy water) and tritium – but I’m not sure about this project. (The reason to care is to understand better the cost implications). But there are a lot of good details here.

---

Anyway, the professors have gotten some attention for their work:

Several groups are considering implementing the Super X Divertor on their machines, including the MAST tokamak in the United Kingdom, and the DIIID (General Atomics) and NSTX (Princeton University) in the U.S. Next steps will include performing extended simulations, transforming the concept into an engineering project, and seeking funding for building a prototype.

Which keeps it firmly in the university/lab sphere, for now. In describing fusion projects, I sometimes think of them as  “Today’s Technology Tomorrow,” because fusion always seems two years away from a major breakthrough. It always has, as long as I’ve followed the subject.

But one can’t help but be impressed by the amounts of ingenuity and enthusiasm being poured into fusion projects. Maybe that’s  motivated by a potentially enormous payoff for the team who can make a project practical – that is, scalable and affordable – but maybe also, even largely, for love of ingenuity and enthusiasm. Those qualities have carried the world a long ways.

A Nuclear Energy Binge to Combat Climate Change

Professor Peter Wadhams off ice
This suggests an academic freak-out:
Geo-engineering techniques such as whitening clouds by adding fine sprays of water vapor, or adding aerosols to the upper atmosphere have been ridiculed in some quarters but welcomed elsewhere. Wadhams proposes the use of thorium-fuelled reactors, being tested in India, which are said to be safer because they do not result in a proliferation of weapons-grade plutonium, experts say. Also, under certain circumstances, the waste from thorium reactors is less dangerous and remains radioactive for hundreds rather than thousands of years.
Wadhams is Peter Wadhams, a professor of ocean physics at Cambridge University. What he’s talking about are the desperate measures he envisions as necessary to mitigate climate change.

The thorium-powered nuclear future represents what he calls a nuclear energy “binge” – the resort to thorium seems to me a bit of a hedge, but he’s only proposing not disposing. He’d probably be content enough with uranium if it came down to that.

His point isn’t about nuclear energy, but about arctic ice and the fact that it’s melting away. Even worse, underneath it - well, in Greenland, anyway - is a lot of methane.
"What we are now seeing is a fast collapse of the sea ice that means we could see a complete loss during the summer by 2015 - rather than the 20 to 30 years talked about by the UK Meteorological Office. This would speed up ocean warming and Greenland ice cap melt and increase global ocean levels considerably as well as warming the seabed and releasing more methane."
It seems unlikely that that the largest nuclear facility building project in the history of atomic energy (or the largest effort to seed clouds) would make a difference by 2015 (though it could, of course, make a big difference over time.) Which makes Professor Wadham’s call seem like a freak-out, a bit frantic, but even if that were true, he’d has plenty of reason for it.
---
Wadhams has been talking about the snow melt for awhile (I mean, beyond the fact that it’s his specialty.) I poked around the Cambridge archives and found this from 2010.
However, comparing the sea ice extent that had been predicted by the IPCC models for recent years with what was actually observed shows that the models, as they stand, underestimate the rate at which the ice is disappearing. Wadhams believes that this is due to feedback loops which come into play as more ice melts in the summer, but which have not yet been properly accounted for in the models.
So he’s been saying this for a couple of years at least and hopping ahead of other experts – I think the Guardian has picked up on it now because of the recent dire warnings about the methane lurking under the ice. Already, a fair amount of seepage has been recorded.
Writing in the journal Nature Geoscience, the researchers say this ancient gas [ancient because the methane’s been there since antiquity] could have a significant impact on climate change.
Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability.
But If read the stories correctly, it’s tough to pin down how much methane is there, though a fair amount of inquiry is devoted to figuring it out. But here’s the thing: if the ice melts away by 2015, then there isn’t much time before the methane escapes its icy prison (though I think it lies under the ground, not the ice, so it won’t all go in a single burp.)

In any event, the goal ultimately might be to account for the methane in calculating its impact, not to keep it where it is. Professor Wadhams’ geo-engineering ideas might intend to produce snow in the Arctic, but it seems very unlikely to happen. So, frankly, does a nuclear energy binge, however much that might benefit the planet in the long run and might occur, hopefully without all the implications of a binge, anyway.

NEI Energy Markets Report (August 27-31, 2012)

Here's a summary of what went on in the energy markets last week:

Electricity peak prices made marginal gains last week across the country. The largest movers were the Western hubs which increased $4-$6 to average $40/MWh in the region. The Eastern hubs barely budged and the Texas hub rose $4 to average $36/MWh. “Power prices across the U.S. moved in mixed directions Tuesday, Aug. 28, finding support from hot weather in California, across the Southwest and Texas but taking on a more bearish bias elsewhere across the country in line with weak spot gas prices. … In addition, generation remains healthy. While several units are slated to shut through September and October, a fairly minimal 22,790 MW is offline nationwide in the meantime, according to IIR Energy. The nuclear generation sector, which could see as many as 30 reactors shut for refueling by the end of the year, represents the largest market share of outages, with 8,337 MW offline. In addition, about 5,568 MW of the total is coal-fired and more than 4,000 MW is gas-fired, IIR said” (SNL Energy’s Power Daily – 8/29/12).

Uranium spot prices fell to $48/lb U3O8 last week. “Although a significant portion of the lowest-priced supply has been cleared from the market, demand remains thin and highly price sensitive at month’s end. Some potential buyers have yet to enter the spot market in spite of the recent drop in the price. In the case of many utilities, there is little room or budget available for inventory or discretionary purchases, and those interested in taking advantage of the price drop must procure management approvals before proceeding. In addition, several market participants still expect that prices could fall even further and, therefore, are delaying purchases in hopes of securing material at even lower prices” (TradeTech’s Nuclear Market Review – 8/31/12).

A Daft Car, Pope Benedict XVI and Nuclear Energy Present and Urgent

Kangoo
The Renault Kangoo Z.E. Ridiculous? You decide
No comment (it speaks for itself):
Pope Benedict XVI is now a bit greener.
The 85-year-old pontiff was presented with his first electric car Wednesday, a customized white Renault Kangoo for jaunts around the gardens of the papal summer residence at Castel Gandolfo.
The story mentions other green initiatives taken at the Vatican City-State.
Benedict has been dubbed the "green pope" for his environmental concerns, which have been a hallmark of his papacy. He has written of the need to protect God's creation in his encyclicals, and raised the issue on his foreign trips and in his annual peace messages.
Under his watch, the Vatican has installed photovoltaic cells on its main auditorium and joined a reforestation project to offset its carbon dioxide emissions.
The Vatican City-State is 800 or so people strong and sits on 110 acres in the middle of Rome. How much influence could it have?
---
I like electric cars because they reduce carbon emissions and because nuclear energy is a plausible source for powering them. But it wouldn’t be fair if I ignored Pope Benedict’s view of nuclear energy. Here’s what he said in 2007 marking the 50th anniversary of the International Atomic Energy Agency:
The Holy See, fully approving the goals of this Organization [IAEA], is a member of it since its founding and continues to support its activity. The epochal changes that have occurred in the last 50 years demonstrate how, in the difficult crossroads in which humanity finds itself, the commitment to encourage non-proliferation of nuclear arms, to promote a progressive and agreed upon nuclear disarmament and to support the use of peaceful and safe nuclear technology for authentic development, respecting the environment and ever mindful of the most disadvantaged populations, is always more present and urgent.
---
I’d never hear of the Kangoo before. Over at Top Gear is this opinion:
The ridiculous-looking Renault Kangoo is actually an inspired choice for families on a budget. It’s huge inside, can cope with all the clobber a couple of kids bring with them and really is cheap.
And:
It looks daft, isn't luxurious, has zero status and yet does its job brilliantly.
And this is a positive review. I think Top Gear may have hit on the reason Renault called it Kangoo. The review seems to be of a gas-powered Kangoo (the electric one is called Kangoo Z.E.), but let’s assume the electric and gas versions are equally daft.

I couldn’t find the origin of the name Kangoo -  a toddler’s attempt at kangaroo, maybe? In French, it’s kangourou. Kangou would probably not be easily grasped outside France. Here's Renault's page for the car. Try not to laugh.

Turkey: Nuclear-Natural Gas Quid Pro Quo?

No argument here:

One of the world’s fastest-growing economies, Turkey has significant energy needs. The majority Muslim nation’s energy demands will double by 2023, according to one projection.

Nuclear Energy perhaps? Turkey has contemplated it for some years, but lacked a partner to help cover the expense of building the facility- running nuclear energy plants is inexpensive, building one is expensive. Now it has a partner – and in an arrangement that seems close to unique:

The $20 billion venture will be wholly financed by a subsidiary of Rosatom, Russia’s state-controlled nuclear energy corporation.

The Russian firm has agreed to build, own and operate the plant for its entire productive life, with spent fuel sent to Russia for reprocessing. The deal represents an unprecedented level of cooperation between the former adversaries.

Various Turkish officials have a lot of questions about this, some of which involve national sovereignty, always a touchy subject. For example, Turkey doesn’t have a nuclear regulator at present and it’s uncertain whether the new plant will be regulated by the Russians or the Turks. Additionally, it isn’t clear which country will decommission the facility. To be honest, these items can be worked out in time – I suspect it is the Russian connection that gives them an air of urgency.

---

Most interestingly, though, there is the strong implication that Russia isn’t doing this solely (if at all) out of the kindness of its heart:

Gas- and oil-producing giant Russia has enlisted Turkish support for its proposed South Stream pipeline to diversify its access points to European markets.

There’s no direct evidence of quid pro quo, though plenty of evidence of heavy negotiation that included both the nuclear facility and the natural gas line – almost every story I looked at yoke them together, which suggests, at the very least, that the two projects represent a single unit that will proceed in sync. In fact, Turkey and Russia signed 17 (mostly) energy-related agreements in one go, which in itself has aroused a good deal of concern in Turkey.

But most of that number [$100 billion in trade] comes from Turkish imports of Russian oil and gas, and some Turkish energy experts cautioned that the increase would do more good for Russia than for Turkey. The deal for the nuclear plant, scheduled to be built over seven years in the Mediterranean city of Mersin, raised further concerns among some Turks of relying too much on Russia.

This is from the NY Times and it too keeps the natural gas and nuclear projects closely linked. Still, even if there is more correlation than causation here, I wondered if there was more to the Turkish involvement in the natural gas line.

---

Indeed, there is a kind of race going on between Russia and Europe to build a viable natural gas line to serve European markets, with Turkey involved in both of them.

The South Stream gas pipeline is intended to provide a direct connection between suppliers and consumers, thus avoiding transit risks and guaranteeing a continuous energy supply for Europe. Nabucco on the other hand, aims to bring Caspian gas supplies to Europe to reduce dependence on Russian gas imports taking a northern route from the Turkish-Bulgarian border to Austria.

The story doesn’t really explain what Nabucco is all about, but it does point out that diversifying the supply of natural gas is important – and it is. Let’s take that as a given.

Nabucco is a consortium formed by Turkey, Romania, Bulgaria, Hungary and Austria. The European Union supports it and so does the United States – because much of the natural gas will come from Iraq. The pipeline itself stretches from Turkey to Austria, with feeder lines from Georgia and Iraq.

The South Stream line, meanwhile, will carry Russian natural gas through Bulgaria and Turkey and on to Italy. This already tortuous route is necessitated by bypassing Ukraine, which wants no part of the project (Russia accused Ukraine in 2006 of stealing natural gas flowing though the latter, a conflict that got bitter quickly; in 2009, Russia rather roughly shut down the natural gas supply to the west for reasons not fully explained, stranding some countries, such as Bulgaria, in the middle of a harsh winter. See here for more on that). Losing the Ukrainian option meant involving Turkey, even if it provides a less than ideal route.

---

Check out the Nabucco and South Stream web sites for a more complete accounting of the pipelines. Note, too, that I have no brief on natural gas pipelines and their doings. In the parlance of American politicians, no winners and losers here. (Both pipelines serve a practical purpose and both serve natural gas-poor Europe. If Nabucco backstops Russian petulance, consider it a bonus.)

In the end, what’s really worth discussing is a 1200 megawatt Russian nuclear facility at Mersin. It’s ultimately up to the Turks to decide if that’s a good idea and so far, and with some dissent, the decision is – yes. It works for Turkey.

NuScale Back in Action with Unexpected Support

The other day, we mentioned Babcock & Wilcox’s small reactor project and its indirect use in the Gubernatorial race in Indiana. Now, another vendor of small reactors, NuScale, has attracted some press attention from Reuters. It’s especially nice to see that NuScale has overcome its financial difficulties.

NuScale staff half-jokingly refer to the first half of 2011 as the "Great Pause," when NuScale could not pay its bills and dozens among its 100 employees at the time had to be let go. It now employs 260 people, and hopes to add another 70 by year-end.

And how did it do this, at least in part?

But NuScale is trumpeting the safety aspects of its new technology, and has found helpful supporters including U.S. engineering giant Fluor Corp, which bought a majority stake in the 5-year-old company last October.

Fluor is no stranger to the nuclear energy business. Start here for more on its activities. Fluor has been around for much of the nuclear age.

Like Indiana, Oregon, where NuScale is located, has no nuclear energy facilities. It closed its one plant, called Trojan, in 1992. But, as with Pence in the Hoosier state, NuScale has found some support from the Beavers.

Yet the NuScale design has managed to win over Oregon's national representatives, who tend to be against nuclear power. Senator Jeff Merkley, a self-described "proud progressive," surprised [NuScale Chief Executive Paul] Lorenzini by throwing his support behind SMRs.

The story talks a bit about other subjects – and is interesting in general – but the key point is that NuScale has found a path forward. There are a lot of hurdles yet to clear in the small reactor arena and some of the numerous competitors will probably fail as the marketplace develops. But let’s at least have the marketplace develop some more before/if the winnowing starts.

If friends knew that I don’t like mushrooms, they might tease me by telling me they love them.

Then I would say, “Mushrooms wouldn’t exist without government help. No one would eat them.”

“But did you see the study that mushrooms are a great source of potassium?”

“More propaganda from the mushroom brigade,” says I. “Mushrooms are just dolled-up toadstools.”

And on and on.

So, in the middle of his story on NuScale, writer Braden Reddall felt the need to get the other side.

"SMRs are just the next chapter in a nuclear industry that can't stand up on its own," said Don Hancock, director for nuclear waste safety at the Southwest Research and Information Center. "So it always has to be funded by the government."

It can’t be fun having reporters calling on you to play the tarantula on the valentine all the time. I wonder if his friends tell him how much they’d like more nuclear energy facilities in the area.

NEI Energy Markets Report (August 20-24, 2012)

Here's a summary of what went on in the energy markets last week:

Electricity peak prices fell $1-$16 last week across the country to all settle below $40/MWh. “Next-day power markets were mixed but generally lower across the U.S. to open the workweek Monday, Aug. 20, as traders eyeballed higher load forecasts in most areas but also weak natural gas prices and an overall healthier generation picture. … Other sources of generation were improving Monday. According to data from IIR Energy, just more than 19,300 MW of various generation was offline across the U.S. early Monday. By fuel type, 3,866 MW was coal-based, while about 8,150 MW was nuclear-based and 1,969 MW was natural gas-driven” (SNL Energy’s Power Daily – 8/21/12).

Electricity production was down 8.3 percent last week compared to the same week in 2011. For the first 34 weeks of 2012, electricity production is down 2.3 percent compared to the same period in 2011.

Indiana: Introducing Nuclear Energy into the Race

pence-gregg
Mike Pence (l) and John Gregg
Indiana has no nuclear energy facilities. It might never have them – well, never say never – and nothing, such as a ban, actually stops the state from having them. But any large infrastructure project needs a local advocate; one with authority in the state helps, too.

So – meet Rep. Mike Pence (R-Ind.), who is currently running for governor of Indiana.
"When you look at much of the industrialized world today, the technology and the safety record of nuclear energy is one that I think Hoosiers ought to be willing to look at, in addition to developing all of our traditional sources of energy and our renewable sources of energy," Pence said.
The story explains that Indiana has flirted with nuclear facilities a couple of times, but has ended up instead as the rare Midwestern state without one. Illinois has 11, for example.
Pence isn’t hiding his enthusiasm for nuclear energy under a bushel. Many of the stories I looked at about this have it in their headlines and ledes. Pence isn’t the least shy in sharing his views.
“We have next generation nuclear power technology under development right here in Indiana,” Pence said. “Known as small modular reactors, this technology is less expensive and easier to deploy than older generations of nuclear power.”
I couldn’t find Pence explaining this in more detail, but he is likely referring to Babcock & Wilcox, which has a fabrication plant in Mount Vernon and will make its mPower small reactor there.
The Babcock & Wilcox Co. manufactures naval nuclear reactors for submarines and aircraft carriers. For security purposes, U.S. military technology will not be transferred to the mPower reactor project; however, the factories already exist and the additional investments for the initial stages of market adoption are minimal. Another advantage is that the reactor is small enough for the reactor vessel head and bottom to be forged in North America. The B&W Nuclear Operations Group’s Barberton, Ohio, and Mount Vernon, Ind., locations specialize in the design and manufacture of large, heavy components. These two locations are ASME N-Stamp accredited, making them two of only a few North American suppliers of large, heavy-walled nuclear components and vessels.
You can learn a lot more about this at the link.

A little more about B&W’s plan:
When you hear the words "green energy" what typically comes to mind is solar and wind power. However, one of the greenest forms of energy is nuclear. And we have an opportunity in Southwest Indiana to be a major player in the next stage of nuclear energy development.
Babcock & Wilcox recently showcased its newly acquired vertical milling machine that will be used for manufacturing nuclear components. The excitement is due to B&W's future launch of the mPower reactor, a small modular reactor that will be used in conjunction with Generation mPower LLC to design the world's first commercially viable Generation III++ power plant.
Back to Pence:
“In addition to developing all of our traditional sources of energy and our renewable sources of energy, we ought to look at adding nuclear energy to our portfolio if it’s economically feasible and keeps our energy costs low.”
Which it would indeed do.
---
John Gregg is the Democratic candidate for Indiana Governor. He served in the Indiana House for 16 years, as Speaker of the house for four of them. He left politics in 2002, did a stint as radio talk show host and won a battle against prostate cancer before reentering politics via this race.
Daniel Altman, spokesman for the Gregg campaign, pointed to disasters such as Chernobyl, Three Mile Island and Fukushima as reminders that nuclear energy can have serious negative consequences.
“John has been talking with Hoosiers for months about how to keep energy costs down for Indiana, while also creating good-paying energy jobs in the state,” he said. “As someone who has worked for two different coal companies, John knows that we have enormous potential not just for coal, but methane, natural gas, biomass and wind energy, and he will work to further develop these industries.”
Well, he’s an energy veteran, which is always a big plus in our book, but clearly not nuclear-friendly. That’s all right: he and Pence provide a clear cut choice in this regard, and that always makes for a good campaign and election season.

Of course, this is a race for Indianans to decide and I have no brief on the candidates. No one is (or should be) a single issue voter – even nuclear energy advocates -  and Pence and Gregg will happily share their thoughts on any number of topics of interest to Indianans. Some of them may even matter more than nuclear energy to a large group of voters.

Still – about Pence’s full-out support: good for him – and for introducing nuclear energy into the campaign, however it goes. That’s a decided value in itself.

Japanese Business to Nuclear Energy: Stay

Reuters has released a poll gauging the attitude of Japanese businesses toward nuclear energy. Based on a number of stories I’ve read, I expected the numbers to be extremely dismal.

And while not exactly warming, they’re not nearly as awful as anticipated, either.

About one in five big Japanese firms wants to see the share of nuclear power in the electricity supply reduced to zero by 2030, a Reuters poll showed, amid a growing anti-nuclear clamor after last year’s Fukushima atomic disaster.

But underlining concerns about a rise in energy costs without nuclear power, the rest of the respondents supported a continued role for nuclear energy, with the biggest group opting for a share of 15%.

A little more specifically:

In the Reuters poll, 19% of big firms sought to cut nuclear power’s role to zero, but 39% called for 15% by 2030, as a majority of companies brace for slower economic growth as reliance on nuclear energy declines.

One-quarter said they wanted to see a 20-25% share and the remainder called for even greater percentages, according to the poll of 400 big firms, taken alongside the monthly Reuters Tankan business sentiment survey. A total of 268 responded during the Aug 6-21 survey period.

The share numbers here represent a rather modest reduction, as nuclear energy supplied about 27 percent of Japan’s electricity before the accident at Fukushima Daiichi. This means well more than half the respondents want the share reduced by less than half to barely reduced at all.

Of course, one would really need a series of surveys on this topic to grasp whether these numbers are growing. It’s bald intuition – and the experience of other industrial accidents such as the BP oil spill – to suggest that as time goes by, the impact of an accident becomes less. That’s been true of the Japanese accident in polls taken both here and in Great Britain. It’ll be interesting to see if this follows through in Japan as well.

Prime Minister Yoshihiko Noda has said he would like to reduce nuclear energy’s share but is awaiting a medium-term energy plan before describing specifics. One can’t blame Noda for treading carefully.

To cope with increased electricity costs amid a prolonged shutdown of reactors, 69% said they would cut expenditure and 36% would seek cheaper power suppliers, according to the poll, which allowed respondents multiple choices.

Underlining conditions of prolonged deflation, 26% said they would pass the cost on to their customers, while 13% would shift operations out of Japan, according to the poll.

Noda has to balance the wants of a sizable constituency – a government poll shows about 47 percent want to zero out nuclear energy – with their need to retain employment and, from the government’s perspective, contribute to the economy. Carbon emission targets weigh in, too.

So the numbers are not great but not so horrible that they make closing the nuclear facilities a key to political survivability – at least, I don’t think that’s what they would show here.

--

In this light, an editorial in the Yomiuri Shimbon (a national newspaper) is less surprising.

Securing the safety of nuclear power plants is of course important. However, factors such as economic efficiency and a stable energy supply are also important in deciding the nation's energy policy. As a country poor in natural resources, Japan needs to have various sources of electricity, including nuclear power plants, to ensure a stable power supply.

Thus the government should promote a realistic energy policy of utilizing nuclear power plants from a mid- and long-term standpoint.

Which probably would not have been written a year ago. The paper also tackles public polling.

It is important for politicians to listen to the voices of the people. However, there is a risk that politicians may slip into populism, depending on how much they rely on public opinion.

A member of an expert panel tasked with analyzing the results of the surveys said, "We don't need politics if opinion polls decide everything."

The results of the surveys should be used as one element in discussing the nation's nuclear policy. The government should avoid having the results directly influence its energy policy.

This is a tougher needle to thread. The editorial goes on to say that people don’t realize that closing the nuclear facilities would hurt the economy and raise unemployment. This is true only in a speculative sense – a lot would depend on the length of time the facilities stay open – but politicians don’t have to be “populist” necessarily to accede to the public will even if it will harm them economically. See Germany for exhibit A.

Regardless, all these elements may suggest a consensus forming around nuclear energy continuing with a lesser share. But if this is the consensus, it’s at best a fragile one. We’ll know more after the energy plan is released.

Uranium of the Sea – and How to Get It – and Why

This is interesting, but it doesn’t seem quite enough:

Japan developed an adsorbent that attaches the uranium-loving chemical group amidoxime to a plastic polymer. ORNL examined the binding process between the plastic and chemical groups and used that knowledge to enhance the uranium-grabbing characteristic of the amidoxime groups on the adsorbent material's surface.

PNNL tested the adsorbent's performance at its Marine Sciences Laboratory in Sequim, Wash., DOE's only marine research facility. Using filtered seawater from nearby Sequim Bay, PNNL established a laboratory testing process to measure the effectiveness of both Japan's and ORNL's adsorbent materials. Initial tests showed ORNL's adsorbent can soak up more than two times the uranium than the material from Japan.

Why would anyone want to do this? With the Japanese, it makes sense because the country is so light on natural resources. But elsewhere?

The article – really an abstract – says that there are about 4.5 billion tons of uranium floating loose in the ocean – about 3 parts per billion – so the effort to find those fissionable needles in the aqueous haystack could pay off for whoever figures out how to collect them economically and then scales up the process to collect a lot of them efficiently. 

But even if someone accomplishes this and to scale, why do it – to what end? There are enough known uranium deposits for another century at least. A hundred years may not seem very long, but let’s say, in that time, thorium comes into its own or recycling used nuclear fuel becomes widespread – or fusion scales acceptably – or mining scouts discover new uranium deposits - then the lifespan for the currently known uranium deposits begins to multiply. So a hundred years may not be a long time, but it’s still enough time for a lot to happen – and just with the technologies and methods we already know much less those we don’t know yet.

In the meantime, perhaps we could learn more about this effort. If it hadn’t already passed, we could attend the – wait for it – Extracting Uranium from Seawater conference, hosted by the American Chemical Society. Having missed that, we can at least look at the conference coverage.

In introducing the conference, World Nuclear News explains why seawater extraction hasn’t caught on commercially yet:

Although these trials proved the principle of uranium extraction from seawater, the cost was prohibitively high - perhaps around $260 per pound. This compares badly to today's most economic mines on land, which produce uranium at around $20 per pound, while resources at higher costs up to about $115 per pound have already been identified that would last more than a century.

This almost gets at motivation, but I think it’s fair to say that, aside from scientific curiosity, the reason to explore this is that uranium will always have a market despite alternatives. At least, that’s the bet being made and probably a good enough one to take a slight risk to win. (I haven’t mentioned, but should, that uranium is useful for nuclear medicine and other purposes outside the energy business. Providing a steady source of uranium also guarantees energy security for whichever countries implement seawater extraction, avoiding artificial or real shortages on the vendor end – and avoiding bad actors among the vendors.)

Just as a scientific endeavor, the conference shows that a good deal of ingenuity is bearing down hard on the cost issue, with scalability perhaps a little further down the priority list:

Conducting research for the US Department of Energy, Oak Ridge National Laboratory has worked with Florida firm Hills Inc. to develop new adsorbent materials. Mats made from so-called 'HiCap' fibers, featuring high surface-areas, are irradiated and then reacted with chemical compounds that have an affinity for uranium. After an exposure period and extraction of uranium the mats require acid washing and conditioning with potassium hydroxide before re-use.

That sounds like – a lot of work. You clearly can’t just throw these mats in the washing machine. But the results make the complex procedure worth the effort.

Oak Ridge said the fibres delivered five-times higher adsorption capacity, faster uptake and higher selectivity than the previous best.

Even better than this outcome? This gets the cost of the uranium to about $135/lb. Still too much, but in the right direction.

Here’s an idea that would prove an economic boon to your local Red Lobster:

Another project presented at the ACS meeting concerned the use of fibers based on chitin - a long chain biopolymer that can be obtained from shrimp shells.

The BBC has a little more on this:

Chitin is a long-chain molecule that is the principal component in crustaceans' shells, but its toughness and its ability to be "electrospun" into fibers that can be made into mats make it an ideal sustainable and biodegradable choice for uranium harvesting.

The stories don’t provide enough other details to gauge this as anything other than an interesting idea – though I’d probably advise the University of Alabama, which is hosting the project, to downplay the whole shrimp shell angle – it suggests a ferocious Old Bay budget. The sustainable, biodegradable angle is far more of the moment.

Altogether? It’s an interesting ongoing inquiry into maximizing a commodity and it does appear to be making progress toward that goal – the efficient production of plentiful, inexpensive uranium.

But that’s rather highfalutin. Instead, let’s celebrate the human capacity to identify and solve problems. That’ll carry us a pretty long way.

NEI Energy Markets Report (August 13–17, 2012)

Here's a summary of what went on in the energy markets last week:

Electricity peak prices fell from $3 to $11 last week across the country in continuing mild weather to settle in a range of $31-52/MWh. Gas at the Henry Hub fell 13 cents to average $2.79/MMBtu for the week, and the rig count continued its decline by another eleven rigs to 484. …

Crude oil rose $1 last week, to average $94/barrel at Cushing, Oklahoma. “The U.S. average retail price of regular gasoline increased two cents this week to $3.74 per gallon, 16 cents per gallon higher than last year at this time. …”

Average nuclear plant availability fell to 89 percent last week. One unit returned to service, and seven shut down. Turkey Point 3 returned to service after a six month refueling and maintenance outage to uprate the unit 15 percent. …

Fox Gets It Right on Emissions – Or Close Enough

Media Matters for America and Fox News are not the best friends in the media landscape, with the former often calling out the latter for what it perceives as bias in its reporting. I have no particular brief on that subject.

But I do recognize that the energy business has done a fair amount to bring down carbon emissions through the increased use of natural gas, renewable energy and nuclear energy (through uprates) – and is quite conscious of it - so I found this report from Media Matters somewhat amusing:

But Fox is ignoring the confluence of factors and touting the decline as a triumph of the free market. A Fox Nation headline today declared: "Free Enterprise Makes the Air Cleaner." On Varney & Company, Fox Business contributor Charles Payne said: "The free market, cleaning up our air. Says a lot about the free market, doesn't it?"

Payne is essentially correct here. We might focus on “bringing down carbon emissions,” though “cleaning up our air” is fine for the purpose. Media Matters says:

The Energy Information Administration announced earlier this month that U.S. energy-related CO2 emissions in early 2012 were the lowest measured for a January-March period since 1992. The report attributed the decline to a combination of three factors: reduced household heating demand during an unusually warm winter, a decline in coal generation due to low natural gas prices, and low gasoline demand as a result of a slowed economy and the shift towards more fuel-efficient vehicles.

Media Matters is correct, too – but you’ll note that it has to include items such as the “decline in coal generation due to low natural gas prices,” which the industry didn’t have to do a thing about – but it did – because it liked that it could bring down carbon emissions (and increase profit, too – let’s not be too naïve here – but let’s not be too cynical, either – this is an unalloyed good outcome.)

I’d also note “fuel-efficient vehicles” as a government-industry mandate/goal, disrupting the purring about the free market, but still – close enough.

If government priorities aren’t all bad, neither are free market prerogatives. The balance between the two can lead to (sometimes heated) arguments, but not the premise. So Payne has a valid argument to make here in favor of the marketplace.

We might have given all the points to Fox News on this one. But:

[Reporter Tracy] Byrnes went on to ask her guest why carbon dioxide emissions -- which are not "poisonous" or "inflammable" -- are even a problem in the first place.

So, there you go.

Plant Vogtle Crane One of Largest in the World

The 560-foot tall lift derrick at Plant Vogtle (Southern Company).
That is one mighty big crane. Here are all the details from Southern Company:
Testing has begun on a major component in the construction of two new nuclear units at Plant Vogtle 3 and 4 – a 560-foot tall heavy lift derrick, one of the biggest cranes in the world.

The derrick, which will be used to move large pieces at the site of the first new nuclear units built in the United States in 30 years, has the capacity to move the equivalent of five 747 jets across the distance of more than three-and-a-half football fields in a single lift.

In addition, major components will begin arriving to the site later this year and early 2013, the first of which will be the reactor vessel for Unit 3. The Unit 3 condensers have arrived from South Korea, where they were manufactured. Unit 3 is scheduled to go online in 2016, and Unit 4 will follow in 2017.

Also at the site, significant work has been done on turbine islands, cooling towers and nuclear islands. Over the next several months, progress will continue to be made in the nuclear island, turbine building and module assemblies.

"The project is progressing extremely well, especially when compared to other large-scale infrastructure projects worldwide," said Joseph A. "Buzz" Miller, Executive Vice President of Nuclear Development for Georgia Power and Southern Nuclear. "The Vogtle 3 and 4 project provides at least $2.2 billion more value to customers than the next best available technology, according to Georgia Public Service Commission staff."

Nuclear Today, Lignite Tomorrow: Germany’s Withering Choices

German Nuclear Plants (Wikipedia)
Color Bloomberg unimpressed:
Chancellor Angela Merkel’s government says RWE AG’s new power plant that can supply 3.4 million homes aids her plan to exit nuclear energy and switch to cleaner forms of generation. It’s fired with coal.
And Herr Dieter Helm, energy policy professor? Also not impressed:
“Angela Merkel’s policy has created an incentive structure which has the effect of partially replacing nuclear with coal, the dirtiest fuel that’s responsible for much of the growth in the world’s greenhouse-gas emissions since 1990,” Dieter Helm, an energy policy professor at the University of Oxford, said by phone Aug. 17. Building new coal stations means “locking them in for the next 30 years” as a type of generation, Helm said.
The problem is that natural gas, inexpensive here, is expensive in Germany, so it isn’t as viable a fuel for large installations. As we’ve seen, Germany’s grid isn’t equipped (yet – let’s be optimistic) to handle the intermittency of solar and wind stably. What Merkel is doing actually makes some sense taken from one angle:
Merkel’s government wants utilities to build 10,000 megawatts of coal- and gas-fired generators this decade to replace older, dirtier generators and underpin a growing share for wind turbines and solar panels.
The problem is: natural gas and especially coal will replace the nuclear energy capacity while wind and solar will contribute additional electricity generation above that, so the trajectory of greenhouse gas emissions is up. But some of the same forces that made nuclear energy toxic in Germany are understandably no more happy with this plan. Or shall we say: unimpressed?
Building new coal generators in Germany isn’t easy. A group of local utilities last month scrapped plans to spend 3.2 billion euros to construct the nation’s biggest hard-coal plant in Schleswig-Holstein after resistance from environment groups and the state government led by the Social Democratic Party and Green Party.
Can it be said that Germany’s options are withering away?
“It’s very alarming that leading German politicians praise a plant run on lignite,” Gerald Neubauer, a Greenpeace campaigner in Germany focusing on energy issues, said by phone on Aug. 16. “Burning lignite spews more carbon dioxide than using most other energy sources, and mining it inflicts major damage on the environment.”
I almost feel like saying: This is what Germany wanted and this is what it got. But this transition is just depressing, however you look at it, a casebook study of bad policymaking.
Great story for Bloomberg by Stefan Nicola and Tino Andresen. Do read the whole thing.

The Most Polite Strikers Ever and Nuclear Energy in Canada

candu fuel assembly
The CANDU's fuel assembly
Way up north, a group of nuclear engineers are striking against contractors of Canada’s Candu Energy. They haven’t had a new contract since January 2011 and, presumably, want to negotiate a new one.
Striking nuclear engineers from SNC-Lavalin Group Inc's Candu Energy subsidiary escalated their dispute with the company on Wednesday, setting up picket lines at Ontario reactors for the first time and delaying shift changes at the plants.
Uh-oh. Does this close the plants?
The reactors' operators, Bruce Power and Ontario Power Generation, both said the pickets do not threaten safe operations at their facilities.
"They delayed staff coming in but there was no impact on operations," said Ontario Power Generation (OPG) spokesman Ted Gruetzner.
Canadians being as they are, the whole thing seems very polite.
"We decided to do this to try to get our customers to send a message to our employer that it's time to do something about this," said Michael Ivanco, a senior scientist and vice president of the union.
And:
Following the morning picket, Bruce Power announced that it has struck a deal with the strikers that will ensure no further picketing at the Bruce plant.
None of the stories I’ve seen have said anything about how contract negotiations are going or even if such negotiations are happening. So we can’t assume anything – well, except that strikes and pickets can happen at Canadian nuclear energy facilities without shutting down the plants.
Everyone is operating within the spirit and letter of the law – I looked for, and couldn’t find, editorials from local newspapers weighing in, and news stories about this haven’t escapes the business pages - so we’ll just have to wait and see what happens next.
---
It’s an old joke that Canadians are the tidy cousins to the anarchists to their south, but consider: nuclear energy in Canada contributes to a fairly responsible mix of energy types:
Canada generated 603 billion kWh in 2009, of which about 15% was from nuclear generation, compared with 60% from hydro, 15% from coal and 6% from gas. Annual electricity use is about 14,000 kWh per person, one of the highest levels in the world.
Well, I guess energy efficiency could be better, but I wonder how much of that kilowatt usage has to do with avoiding deep freezes. Still, if Canada scales back on coal in favor of nuclear energy (it is building an 18th reactor currently) or natural gas or renewable energy beyond hydro, it will be near perfect on the environmental front. Still, energy security is enhanced by using coal, as Canada mines nearly all of it domestically.
---
Canada uses a home-grown technology for its nuclear reactors, called CANDU. These reactors use unenriched uranium – which saves money by bypassing enrichment – which is possible because the nuclear reaction is moderated by heavy water (deuterium oxide) – an additional expense. CANDU stands for Canada deuterium uranium. (Look here for a much fuller explanation of how the CANDU reactor works. It’s really fascinating.)
Canada chose this method in part because it didn’t have access to enrichment facilities when it began its nuclear energy effort in the 50s, but it has stuck with it and built a global business on it. The CANDU site lists several international buyers, including China and India, the latter creating its own CANDU-like design to create a native industry.
Within Canada, all but one of the operating reactors are in Ontario, with the exception being Gentilly in Quebec. Consequently, 56 percent of electricity in Ontario is generated by nuclear energy with hydro second at 22 percent.
---
How popular is nuclear energy in Canada? Although this poll from Innovative Research Group released this year covers the whole country, it’s probably fairest to focus on Ontario. For example, the whole country is against building new facilities by 63-33 percent, not great. But in Ontario, 48 percent support the proposition (and Saskatchewan is in the 40s, too, maybe because of talk of using nuclear energy to extract oil from the tar sands.)
But the majority (or plurality) of Canadians think nuclear energy is dirty, expensive and overseen by vipers – “63% distrust big nuclear energy business” - except, when the provinces are broken out, in Ontario. Is knowing nuclear energy to like it better? It would seem so – plus, I wager, more effort was made in Ontario to explain its benefits.
There’s likely some overhang from the Fukushima Daiichi accident impacting these numbers, but they do suggest that Canadian nuclear interests need to offer some facts and figures to the public west of Ontario. It’s not that it needs to be a love feast – you can’t be loved by everyone everywhere - but it just isn’t true, for example, that nuclear energy is more expensive that solar power, as most Canadians believe. Just getting the facts straight would do a world of good.

Examining the Data in the INL Cave

Thanks to the folks at the ANS Nuclear Cafe for pointing to this video from Idaho National Laboratory's Center for Advanced Energy Research. It's all about the CAVE: a "computer assisted virtual environment" that enables researchers "to literally walk into their data and examine it."

Very cool stuff. Leave your comments here, or over at Reddit.

Nuclear Energy and Those Who Are Reasonable

It should come as no surprise that environmentalists oppose the use of nuclear energy in the same way they oppose coal or the fracking technology that is unlocking huge new reserves of natural gas. Currently nuclear energy provides about twenty percent of the electricity used in the U.S. Their attack on coal—led by the Obama administration—has driven its use down from just over fifty percent a few years ago to about 47% today.

Not to mention the rise of natural gas. But you’ve got to take your triumphs as they come.

---

In Germany:

[Holger] Arntzen is now project manager of Wind Comm, a nonprofit that supports wind farm development. For him, the key to stopping the backlash against the power lines is to do more to inform Germans that the nuclear phase out comes with a price and changes in lifestyle.

"To show what is possible, and how I, as a citizen, can influence the load on the grid, like putting on my dishwasher only when the sun shines, because we have a lot of photovoltaics. Or waiting on my dishwasher if we have no wind," he says. "People must accept that the post-nuclear phase has a direct impact on how I live, how they live."

Here’s hoping Arntzen, the wind and his dishwasher stay synced or he’ll be eating off the floor in no time.

From Andy Lemke at Forbes, providing a primer on issues around nuclear energy.

At the time of this writing, nuclear energy has support from both Democrats and Republicans in the United States. While it isn’t a  partisan issue, it is generally divided by those well informed on the topic and those who are uninformed. Between those who trust the  scientists / engineers and those who do not. Between those who are reasonable vs. general skeptics.

A pro-nuclear energy writer trying really hard to be even handed. (still good and he’s right - nuclear energy lost its partisan flavor some time ago.) 

Why We Need to Keep a Level Head About the Nuclear Butterflies from Fukushima

Over the last few days, we've seen thousands of stories around the Web concerning a study that concluded that radiation released into the atmosphere from the Fukushima Daiichi Nuclear Power had caused mutations in the local population of butterflies. At the same time, another piece of research noted that there hasn't been any observable effect thus far on people.

When I read the story, I do what I always do, and shot off a note to Ralph Andersen, NEI's chief health physicist. Here's what he had to say about the study:
Please note that there are species of plants, insects and animals that are particularly sensitive to changes in environmental conditions, including radiation. The pale grass butterfly is among the most sensitive, which is why it was selected for study following the accident at Fukushima Daiichi.

This article provides a rational perspective on what has been found, what it may mean, and what it doesn’t necessarily mean.

Similar findings in some species of biota were detected around Chernobyl in the first few years after the accident there, but impacts on the overall environment and ecology were relatively small and the area today is considered by scientists to be verdant and robust in regard to plant and animal life.

Fukushima Daiichi represents a major accident with significant radiological releases and there are and will be discernible consequences for some years to come. Our emphasis here is on taking actions to prevent such an event in the US and globally.

In regard to understanding the consequences there, we remain open-minded and objective, gaining (and sharing) a fact-based perspective on what it is and what it isn’t.
Good advice, and just the sort of guidance we ought to be paying attention to when we read headlines in the media. In the meantime, some nuclear bloggers have taken a closer look and have shared some similar thoughts. Please visit Atomic Insights and Nuclear Diner for more. Also, be sure to check in with the conversation on Reddit.

What Does the NRC’s Order on Waste Confidence Mean for New Plant Licensing?

DryCaskStorage1-300x2252
Dry cask storage
It is not every day that the Nuclear Regulatory Commission advises everyone to “take a deep breath,” but when it comes to people misconstruing the facts about new plant licensing activities following a recent order, that is exactly what happened.

In a nutshell—last week, the NRC issued an order saying that it would not issue final reactor licenses or license renewals until the agency addresses a recent federal court ruling on waste confidence. Many people and some news articles mistakenly reported that this means all current licensing reviews and proceedings will come to a screeching halt, which is simply not the case. The order basically means that licensing reviews will move forward, but that final licensing will be put on hold.

The NRC clarified its position in a blog post late last week:
Let’s be clear: Tuesday’s Order was not a “Full Stop” to NRC’s licensing process. The Commission stated that licensing reviews should move forward—only final licensing was put on hold.
NEI’s Vice President and General Counsel Ellen Ginsberg weighed in:
The commission’s order is helpful in that license applicants can continue to pursue their licenses. Although there may be some delay in issuing some renewed licenses, NRC regulations provide that plant operation can continue beyond the original license term and until there is a decision on the renewal application, so long as it has been filed in a timely manner.
A level-headed article in Forbes’ over the weekend provides further background on the NRC’s order and how it relates to new plant licensing activities (bolded text added by me for emphasis):
There has been some fist-bumping this week in the anti-nuclear sector over the recent vacating of two NRC rules by the U.S. Court of Appeals for the District of Columbia Circuit in June; the waste-confidence decision and the storage rule. The judges felt that the agency had failed to conduct an environmental impact statement, or a finding of no significant environmental impact, before ruling that it is safe to store nuclear waste in wet pools and dry casks without a permanent solution in sight. But it was just that the initial NRC rule was too vague, not that this type of storage is unsafe (platts NRC Ruling).
In response, the NRC this week voted unanimously to delay final approval of licenses for new nuclear plants, or renewing the licenses of existing facilities, until the agency responds with a more complete ruling and addresses the dilemma of long-term nuclear waste storage across the country.
The 24 environmental groups that petitioned NRC to respond to the court are acting like they actually stopped all action on nuclear licensing (Marketwatch NRC Ruling). While no final decisions will be made in issuing licenses, the process for licensing new and existing plants will continue as before, the NRC said, which means the impact to the industry will be minimal.
Also, reactors can operate even after their present license expires as long as it is the NRC that is dragging it out. And most reactors have already been relicensed in the last ten years.  Only 18 out of 104 reactors are not and primarily because they have to operate beyond 20 years before they can apply. The four new GenIII plants being built at Vogtle (Georgia) and V.C. Summer (South Carolina) are also not affected at all since their licenses have already been issued.
The NRC’s blog post continues:
Essentially, the Order represents a regulatory agency taking a deep breath while trying to decide the best way to satisfy the Court.
So, let’s all follow the NRC’s advice: inhale, exhale.

How the North Anna Nuclear Power Plant Weathered the 2011 East Coast Earthquake

Dominion Virginia's North Anna Power Station
We're coming up on the first anniversary of the 2011 earthquake that jolted the East Coast of the U.S. While the quake did little damage -- other than fraying the nerves of millions who never experienced even a tremor that small all of their lives -- plenty of folks were moved to ask questions about the safety of nuclear energy facilities, especially as the quake came just months after the accident at Fukushima Daiichi.

As it turned out, virtually all of the plants on the East Coast endured the event without missing a beat. The only exception was Dominion Virginia Power's North Anna Power Station. North Anna was the nuclear facility closest to the epicenter of the quake in Mineral, Virginia.

When the quake struck, the facility shut down safely and automatically, just as it was designed to do. Just ahead of the anniversary of the quake, the team at Dominion Virginia has published a video recounting how its team responded to the earthquake, inspected it to ensure that it could be re-started safely and got the plant back into service



As you might recall, 2011 was quite a year for America's nuclear energy facilities, as plants across the country successfully endured a series of extreme weather events, something we chronicled in the following interactive graphic:

A Nuclear Namibia Nearer Than Naught?

windhoekIf you’ve read enough of our posts here, you know we like to keep up with what’s happening around the world – who’s interested in nuclear energy, who’s building facilities, and who’s making a big mistake – the aspirational, the inspirational and the laughable. But even when you pay close attention, a surprise will come along now and then:

The Minister of Mines and Energy (MME), Isak Katali, says the inadequate supply of power in Southern Africa leaves the door open for the possibility of a nuclear power station in Namibia.

Namibia? Really? It could use the development – half of its 2.1 million people live in poverty – and the country has enough uranium deposits to ensure energy security. It also has a stable government, no small thing.

Namibia currently imports about 50 percent of its electricity and is suffering shortages despite this (the story doesn’t really explain why).

Namibia will face a shortage of about 80 megawatts (MW) of electricity by this coming winter.

[Minister of Mines and Energy Isak] Katali said the deficit will continue to increase every year, with a shortage of 300 MW forecast for 2015.

As a net importer of over 50 per cent of its electricity demand, Namibia will always be directly affected by the regional power supply situation, which has been critical since 2008.

Katali gave his assurance that his ministry has been hard at work with power utility NamPower and the Electricity Control Board to speed up the completion of planned energy generation projects.

Namibia's main source of power generation, the Ruacana hydropower station, will be boosted with the installation of a fourth generator unit, and when commissioned in March, an additional 92 MW will be added to the current installed capacity of 249 MW at the power station.

And now nuclear – this story is from February, before the more recent addition of nuclear energy to the conversation. How seriously should this be taken? Well, let’s say it’s in the early talking stage right now.

"I am not saying we will have a nuclear plant, all I am saying is that government through our ministry and the electricity supply industry are looking at all power sources, among them, wind energy, hydro and coal-fired stations, a solar thermal collector and the possibility of a nuclear power station in the future," he [Katali] said.

Especially in terms of carbon emissions, Namibia has been exceptionally responsible in its energy profile, favoring hydroelectric and thermal power. Nuclear energy could actually make a good fit. Or would it?

With the country scrambling for new energy sources, including coal-fired power stations, biomass and wind power, nuclear aspirations are seen as contrary to government's advocacy for green energy.

Oh, really? Loads of electricity and no emissions? It solves almost all of Namibia’s energy issues in one swoop – no need to import electricity, a consistent source of generation and an engine for further modernization. (I can’t help but think that small reactor vendors would find a welcome home here, too, able to keep costs down if that’s an issue.)

We’ll keep an eye on it – who knows, it could prove a model for Africa.

---

One of the reasons Katali is thinking of nuclear energy right now may be this:

A new commission to coordinate and promote the development of nuclear energy in Africa is set to become fully operational after key founding documents were finalized and adopted. South Africa has agreed to host the commission in Pretoria.

I imagine the IAEA is involved in this effort, though it isn’t mentioned in the story. But the goals of the new organization show that it is serious in intent and somewhat modest in affect at this early juncture:

Afcone chairman Abdul Samad Minty of South Africa said that the commission "could play a useful role to facilitate the implementation by African states of the relevant legally binding instruments and codes of conduct on nuclear safety and security, and have in place their respective nuclear safety and security infrastructures." He noted, "A key aspect of our work is to promote nuclear sciences and applications."

Namibia isn’t listed among the originating members. They are: Algeria, Burkina Faso, Cameroon, Ethiopia, Kenya, Libya, Mali, Mauritius, Senegal, South Africa, Togo and Tunisia. It’s a start.

Windhoek, the capital of Namibia. From a blog about the city’s night life (!): “For many of us born in the land between the Kalahari and Namib deserts it is the only big city we will ever know and for many others it will be the smallest they’ll ever know. To some it is an African city with European hopes, for others a European city whose sunshine and blue skies are the only betrayals of its unabashed Europeaness but for us of this land, Windhoek is our eternal city. The dwelling place of our gods and the sacred resting place of our ancestors.” And the bar scene? Read the site for that.

Japan: Onagawa Good - Emissions Very Bad - Nuclear Energy?

Onagawa[3]
Japan's Onagawa Nuclear Power Plant
The nuclear facility that was nearest the epicenter of the 2011 earthquake in Japan was not Fukushima Daiichi but Onagawa. How did it do?
An IAEA team of international experts on Friday delivered its initial report at the end of a two-week mission to gather information about the effects of the Great East Japan Earthquake on the Onagawa Nuclear Power Station (NPS), saying the plant was "remarkably undamaged".
A little more:
Onagawa, facing the Pacific Ocean on Japan's north-east coast, was the nuclear power plant closest to the epicenter of the March 11 magnitude 9.0 earthquake that struck Japan and resulted in a devastating tsunami.
The plant experienced very high levels of ground shaking - among the strongest of any plant affected by the earthquake - and some flooding from the tsunami that followed, but was able to shut down safely.
The story doesn’t mention this, but Onagawa also acted as safe harbor for the people of the town, with over 200 taking shelter inside the plant. More on that here.
Within the nuclear plant, facilities are pristine, electricity flows directly from Japan's national grid, and evacuees can use its dedicated phone network to make calls.
"The general public isn't normally allowed inside, but in this case we felt it was the right thing to do," company spokesman Yoshitake Kanda said.
Just so.

There were a fair number of stories over the last few days about the Japanese government pledging to use less nuclear energy at a annual remembrance ceremony at Nagasaki. That didn’t seem right – even though Japan may well end up using less nuclear energy – because using the ceremony to announce it just seemed crass.
This report seems closer to right:
In his address, [Prime Minister Yoshihiko] Noda said "we aim to establish an energy structure in the mid- to long term in a form that will reassure the people of Japan, under a basic policy of reducing our dependence on nuclear power," without elaborating.
This is much gentler, although Noda still walked it back a bit later. Nuclear energy really isn’t the issue here.
"The international community must act now by taking the first concrete steps toward concluding the Nuclear Weapons Convention," Mayor Tomihisa Taue said during the city's annual peace ceremony at Nagasaki Peace Park.
That’s the issue.

Japan without (much) nuclear energy:
Japan, with only two working nuclear power plants, has discharged a record high amount of carbon dioxide in the year ended March 31 as it relied on crude and fuel oil to support its energy requirements.
According to Bloomberg calculations based on data provided by Japan's 10 power utilities, the companies released a whopping 439 million tons of CO2 for the year, a 17 per cent jump from 374 million tons a year ago.
Oil and crude? I wonder how the air quality is doing.
"Objectively speaking, there is no doubt that it is more difficult to achieve the 25 per cent reduction goal than before," Naomi Hirose, president of Tepco, said in June.
Objectively speaking.
Onagawa.
