[Video] Inside Reactor1 torus room, leakage point not identified
Tepco investigated Reactor1’s torus room on 6/11/2014. Torus room is where to contain the donut-shaped coolant facility of the reactor.
This May, Tepco identified one of the leakage points of coolant water from the vessel. (cf, [Video] Tepco identified a leaking part on reactor1 vessel / Pipes are rusted and starting deteriorated [URL])
In order to identify the next leakage point, where the leaked coolant water goes out to turbine building, Tepco ran another investigation robot of Hitachi-GE Nuclear Energy, LTD above the suppression chamber.
However from the investigation of visual inspection and also by using tracer (clay particle), they did not find the water moving out from 2 of 5 joint parts of the pipes.
The rest of 3 joint parts couldn’t be investigated due to the obstacles.
Tepco has been inquired why they don’t color coolant water to trace the leaking part, and also to see the leakage to the Pacific by several media. Tepco hasn’t implemented it or even explained why they don’t.
Leurs investigations par inspection visuelle et aussi avec traceur (particules de boue) ne leur ont pas permis de trouver de fuite sur 2 des 5 raccordements de tuyaux.
Les 3 autres raccordements n’ont pas pu être examinés à cause d’obstacles.
Plusieurs organes de presse ont demandé à Tepco pourquoi ils ne colorent pas le liquide de refroidissement pour trouver l’origine des fuites et aussi repérer les écoulements dans le Pacifique. Tepco ne l’a pas fait et n’a même pas expliqué pourquoi.

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.
