Reactor 2 may be over 90℃

Reactor may be 90℃, not 70℃.

Cold shut down is based on the assumption that the heat gauge has 20℃ of error.
The definition of “cold” shut down is when the bottom of the temperature is below 80℃ because it may be 100℃ taking the error into consideration.

A Japanese independent journalist tweeted like below.

あれ?2号機95度って聞いてるけど?まだ70とか言ってんの?内部は95で焦ってるよ? Source
What ? I heard that reactor 2 is 95℃. Are they still saying it’s 70℃ ? People inside of Tepco is pressed to say it’s already 95.

騙されてるとゆーか、内部の温度計は一部分にだけ設置、かつ性能は普通なため、プラマイ20度の違いはあるわけです。あとは煙の量などから判断するわけですが。今現在は85度以上になっており、煙も多く出ていることからゆうに95度はあると判断しているようです。ただその情報がすぐに国民に Source



The heat gauge is not enough, and it has error of 20℃, so they assume the temperature from the amount of smoke as well. but the gauge is actually showing over 85℃, and lot of smoke is coming up. They therefore seem to judge it’s over 95℃.

The problem is, the data is not published to the people. However, because a lot of people are wanting to know that, they shouldn’t publish the data maybe. but we have the right to know. It’s difficult.

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.
