Nearly half of 350 contaminated water tanks can’t even last for 5 years
According to the report that Tepco submitted to Nuclear Regulation Authority, about half of the flange type tanks can’t last for 5 years.
Flange type tanks are easy to build. In order to catch up with the rapidly increasing contaminated water, Tepco is building this type of tanks instead of the welded tanks. However, these are more vulnerable to leak. Currently there are 350 flange type tanks in Fukushima nuclear plant area.
Normally flange type tanks last for 5 years. However, because some of them were provisionally built, they last shorter than 5 years.
In the map below, red represents the tanks that can last for 5 years. Blue represents the tanks that can’t last for 5 years.
Près de la moitié des 350 citernes d’eau extrêmement radioactive ne tiendront pas 5 ans
Selon un rapport que Tepco a remis à la Nuclear Regulation Authority, environ la moitié des citernes à joints ne tiendront pas 5 ans.
Les citernes de type jointif sont faciles à monter. Pour faire face à la montée rapide des eaux extrêmement radioactives, Tepco construit ce type de citerne au lieu des soudées. Or, elles sont plus susceptibles de fuir. Actuellement, il y a 350 citernes jointives dans la centrale nucléaire de Fukushima.
Normalement, les citernes jointives durent 5 ans. Or, certaines ne tiendront pas autant parce qu’elles ont été construites provisoirement. Sur le plan ci-dessous, le rouge représente les citernes pouvant tenir 5 ans, le bleu celles qui ne tiendront pas 5 ans.

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.
