Tepco is going to attach a freezing machine to water circulation system



Following up this article..Tepco plans to increase water injection of reactor 3

Tepco is going to increase the amount of water to inject only for reactor 3.
It is because the coolant water is heated for summer, but it suggests the situation of reactor 3 is more severe than other 2 reactors.

In the daily press conference of 5/28/2012, Tepco announced that they are going to attach a freezing machine to the water circulation system.
Specifically, it will be attached to the facility called buffer tank located after desalination equipment and cesium removal system.

Tepco estimates they can keep the temperature of each reactor under 65 ℃, which is 15 ℃ lower than the safety limit regulated by Nuclear and Industrial Safety Agency.
However, there was no explanation that how much the temperature would be if they don’t rely on the freezing machine.

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.
