Winter cold may freeze and break the water purifying system

Water purifying system of Fukushima has the hose which runs over tens of kilometers, outside. Most of the parts are made of usual vinyl chloride material, which you can buy at a supermarket.

There is a possibility that it is frozen and has blownout because of the cold weather.

Tepco states that if the weather is not unusually cold – it would last, but it has no basis as always.

According to the specification of the hose, it does not last if it is colder than 0~ -5℃.

Last January and February, in the area around Fukushima there were only 5 days when the lowest temperature was warmer than 0℃ and there were 15 days when the lowest temperature was below -5℃.

The water injecting part has the water flowing continuously, but at other parts contaminated water has stopped being subject to the speed of water processing.

Tepco states they will wrap the hose with adiabatic material, where the low level of contaminated water goes but they can not do anything for the parts where the high level of contaminated water goes because you can not even get close to those parts.

If the hose experiences a blowout – high levels of contaminated water will leak or building will be filled with highly contaminated water. In that case, there is no way to specify the broken part except via a person actually walking along the hose and inspecting it.


冬本番 福島第一 冷却ホース凍る恐れ

2011年12月26日 朝刊

本格的な冬の訪れで、福島第一原発の「冷温停止状態」を保つのに不可欠な塩化ビニールホースに、凍結やそれに伴う破裂などトラブルへの懸念が出ている。タービン建屋から高濃度汚染水を移送して浄化、その水を原子炉の冷却に使用-。水の循環に使われているホースは全長十数キロに及び、破裂すれば汚染水が漏れることになるため、東電も対策を検討している。 (志村彰太)

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.
