Faulty Thermometer Likely Cause of Fukushima Temperature Rise

Last week, we alerted our readers to reports out of Japan that the temperatures inside Unit #2 at Fukushima Daiichi were rising. At the time, we noted that some of the reports of the news were, "rather breathless." That judgment has been borne out, as we received the following welcome news from Japan overnight:

A faulty thermometer is likely to blame for rising temperatures inside a stricken nuclear reactor at the Fukushima-Daiichi plant, authorities said Monday, as Japan prepares to mark one year since a devastating earthquake and tsunami triggered a nuclear meltdown.

[...]

A nuclear expert agreed that a faulty temperature gauge inside the Unit 2 reactor is the most likely cause for the higher heat reading.

Michael Friedlander, a former senior operator at U.S. nuclear power plants, told CNN that the prospect of another catastrophic explosion at the Fukushima-Daiichi is "virtually zero."

"If the reactor was going to become critical it would have become critical in March of last year, not now," he said.

We'd be remiss if we didn't not that the first person who raised the possibility of the faulty thermometer was none other than Will Davis at Atomic Power Review.
