Cold weather destroys water cooling system

Following up this article ..Winter cold may freeze and break the water purifying system

As exactly warned, water cooling system keeps having water leakage at various points.
On 1/29, Tepco announced they found water leakage at 14 points, 7800 L in total. That is because frozen water in pipes caused leakage at joint parts from the cold weather.
Tepco claims it’s the water after purification or plain water from dam, none of it has leaked to the sea.

At 9:35, heat exchanger stopped after 40 L of contaminated water leaked from the pipe.
At 9:50, Tepco employee found 600 L of contaminated water leaked around the flow monitor of emergency pomp. There was a water leakage even at reactor 6.

福島第一、凍結で水漏れ続発 東電「冷却には影響ない」

東京電力福島第一原発で29日、燃料プールや原子炉の冷却装置で水漏れが相次いで計14件にのぼった。冷え込みが続いたことから、装置内の水が凍ってふくらみ、配管のつなぎ目などで破損を起こした。プールや原子炉の冷却自体には影響はないという。

漏れた水の量は計約7800リットル。いずれもダムから原子炉の冷却用に引いた淡水や、放射能汚染水を処理した後の水だった。4号機の燃料プールの冷却装置では29日午前9時35分、プールの水を冷やす熱交換器の配管あたりから約40リットルが漏れて装置が一時停止した。午前9時50分ごろには非常時に使う予備の原子炉への注水ポンプに取り付けた流量計の付近の配管で水漏れがあるのを東電社員が見つけた。最大で600リットル漏れたとみられる。

東電によると、6号機のポンプの冷却水の配管などほかに12カ所で水漏れが起きた。いずれも淡水か処理後の水で海には漏れていないという。

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.
