In the press conference of 2/13 PM, Tepco announced they lost the heating gauge of reactor 2.
Reactor 2 marked 93.7℃ at 2/13/2012 11:00, but it went to 276.4℃ at 17:00.
Tepco is asserting the heating gauge is broken.
The heating gauge is thermocouple, Tepco tried to check resistance but immediately after the test, the heating gauge indicating 276.4℃. The resistance was about 500Ω. Tepco is asserting the wire is nearly broken.
The reason why it was broken is not known. The meter is not indicating error message.
The heating gauge is still showing over 270℃. Other 2 heating gauges are showing about 31℃, but they are not planning to check the resistance of those 2 heating gauges. Tepco has no plan in case other 2 are broken either.
Teoco explains they are not going to put boric acid but will not decrease the water amount.
Additionally, if they misread 276.4 to be in Fahrenheit, it’s 135.8℃.
This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
