[Reactor4] Actual Fukushima worker “In short, it was a design error.”

Following up this article..[Reactor4] Coolant system is still running without proper equipment

 

Actual Fukushima worker Happy11311 tweeted about the failure of the back-up coolant system in SFP4.

The back-up pump was supposed to be started when one of the two pumps stoped, but that one was not supplied with power either, it didn’t work. In the simple put, it was the design error and lack of checking. They are investigating the cause seemingly but I wonder if humidity or salt damage are involved..

Many parts of the coolant system were built provisionally, they didn’t have enough time on designing and checking. It has been a year, it can’t be allowed to leave some parts unchecked yet. Now again, it’s ”look after leap”.

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.
