Reactor4 still remains frail for Tsunami

Following up this article..Actual Fukushima worker “In case of the major aftershock, all the reactors will be in crisis”

Tepco emphasizes they reinforced reactor4 against earthquake resistance, but actual Fukushima worker Happy11311 comments it’s only for the SFP4 and Tsunami guard is still in the temporary state.



Good morning, Mr. Happy11311. Yesterday, news reported Tepco built pillar under SFP4, but does it have base isolation system of earthquake ? and there was heavy equipment on the top floor but is Tepco reinforcing the entire building and Tsunami guard ?





Good evening. The pillar is not for seismic isolation building, just for the bottom of SFP4. (didn’t answer the question about base isolation system of earthquake) Now Tepco is not doing anything to reinforce the building. Tsunami guard remains the temporary state as well.



From the photos of reactor 4 which Tepco released on 5/28/2012, the Tsunami guard is only the debris collected in nets.

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.
