    Vers 6:24 le 30 juin 2012, l’alerte a été donnée d’un problème du système de refroidissement de la SFP4 (piscine du réacteur 4). Ce système s’est automatiquement arrêté. Aucune fuite d’eau confirmée.

    2)・なお、システム停止時の4号機使用済燃料プール水温度は約31℃で、プール水温度上昇率は0.486℃/hと評価。・現在、システムが停止した原因を調査中。・新たな情報がわかったら、改めてメールにて知らせる。(以上、東電からのメール、8:19)

    La température de l’eau de la SFP4 était de 31℃ lorsque le système de refroidissement s’est arrêté. Tepco estime qu’il est monté de 0,486℃ /h. Actuellement Tepco recherche ce qui a provoqué cet arrêt. Tepco enverra des mises à jours dès qu’elle aura d’autres informations.

    Le journal Sankei rapporte le même problème. [http://sankei.jp.msn.com/affairs/news/120630/dst12063011190002-n1.htm]

  3. WHAT SPENT FUEL POOL. WHERE IS IT, I BET IT WENT KAPUT THE OTHER NIGHT WHEN I SAID SOMETHING BIG’S HAPPENING AND JNN CAM WAS FULL OF RADS, AND GUESS WHAT!!!! THERE’S TONS OF YOUTUBE VIDEOS ON IT, YEAH GO SEE, SEARCH CRITICALITY EVENT JUNE 29 2012, AND THIS ONE W W W .youtube.com/watch?v=6zDFlI0GzQQ&feature=plcp

    1. Thank you for posting the link, going to check it out now. Can’t believe this is being kept out of mainstream media.

    2. Let’s just say I’m speechless after watching the video. There’s no saving #4 after seeing that, along with the other demolitions I’ve seen over the last few days. Something bad must have happened last week and they were either scampering around to try and fix it quickly and made things worse, or with TEPCO’s track record they are trying to cover it up.
      Thanks again for the link.

      1. You’re welcome, glad you seen it, hardly any of the world’s population has.

  4. KILLING IS GOOD JAPAN GOVT? IS IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    THE COST IS THE LOSS OF YOUR NATION! FUUUUUUUUUH!

  5. You can drive a person crazy, japan’s doing that to it’s entire civilian population.

  6. Knowing that TEPCO is investigating makes me feel so much better about the increase in nasty radiation.

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.
