Today Tepco started their press conference 20 mins late, which is unusual.
They did not even prepare documents to explain the current situation of the reactors.
According to their statement, at least 3 troubles are happening.
1) At reactor 3
The water cooling system is not properly working. Water coming into the system and coming out of the system shows similar temperature.
They assume it is because a valve was turned off. The last time it was checked was 11/19/2011. They don’t know why the valve got turned off.
2) At reactor 2
Gas pressure controlling room’s temperature has gone over scale.
It’s in suppression chamber. Because the temperature has gone too high, heat gauge can not indicate accurately. They say other 2 heat gauges are indicating normal temperature ,but they are about 100m away from the place.
Also, because the point is extremely radioactive, nobody can get close to check/replace the heat gauge.
3) At reactor 2
Dry well of container vessel is unusually heated. At 11:00AM 11/27/2011, a heat gauge at the point indicated 85.3 C
However, Tepco state there is no problem because other 5 heat gauges around that point show 65~69C, which is usual, so the heat gauge has gone out of order, just at the same timing of (2)
The heat gauge is in the highly radioactive place so they can’t go to check or fix anyway.
Considering the unusual atmosphere of Tepco at the press conference, Japanese journalists are suspecting they are hiding something crucial again.

About this site
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.
