Fukushima Daiichi Nuclear Disaster What Happened at Fukushima Video Documentary what caused the fukushima daiichi nuclear disaster facts and summary. The Fukushima Daiichi nuclear disaster (福島第一原子力発電所事故 Fukushima Dai-ichi was a series of equipment failures, nuclear meltdowns and releases of radioactive materials at the Fukushima I Nuclear Power Plant, following the Tōhoku earthquake and tsunami on 11 March 2011. It is the largest nuclear disaster since the Chernobyl disaster of 1986 and only the second disaster (along with Chernobyl) to measure Level 7 on the International Nuclear Event Scale.

The plant comprised six separate boiling water reactors originally designed by General Electric (GE) and maintained by the Tokyo Electric Power Company (TEPCO). At the time of the quake, reactor 4 had been de-fueled and reactors 5 and 6 were in cold shutdown for planned maintenance. Immediately after the earthquake, the remaining reactors 1–3 shut down automatically and emergency generators came online to power electronics and coolant systems. However, the tsunami following the earthquake quickly flooded the low-lying rooms in which the emergency generators were housed. The flooded generators failed, cutting power to the critical pumps that must continuously circulate coolant water through a Generation II reactor for several days to keep it from melting down after shut down. After the pumps stopped, the reactors overheated due to the normal high radioactive decay heat produced in the first few days after nuclear reactor shutdown (smaller amounts of this heat normally continue to be released for years, but are not enough to cause fuel melting).

Fukushima NHK Documentary: “Two Years Later”

Le monde après Fukushima Arte

Dans la région de Fukushima, après l’accident nucléaire survenu en 2011, la vie des habitants continue, en intégrant au quotidien la pollution radioactive. Avec gravité, ces familles d’agriculteurs ou de pêcheurs qui s’efforcent désespérément de protéger leurs enfants, poursuivent malgré tout leur activité, encadrée par des outils de contrôle. Attachés à leur terre, ils disent leur haine du nucléaire, que la propagande leur a vendu comme un fleuron de la sécurité industrielle. Une mise en abyme du monde futur, à travers des témoignages de vies fracassées.

Fukushima, chronique d’un désastre.

flag-japanHighly radioactive water pouring out of Japan’s Fukushima nuclear plant  http://www.ndtv.com/article/world/highly-radioactive-water-pouring-out-of-japan-s-fukushima-nuclear-plant-402630  Reuters  August 07, 2013  TokyoHighly radioactive water from Japan’s crippled Fukushima nuclear plant is pouring out at a rate of 300 tonnes a day, officials said today, as Prime Minister Shinzo Abe ordered the government to step in and help in the clean-up.

The revelation amounted to an acknowledgement that plant operator Tokyo Electric Power Corporation (Tepco) has yet to come to grips with the scale of the catastrophe, 2 1/2 years after the plant was hit by a huge earthquake and tsunami. Tepco only recently admitted water had leaked at all.
Calling water containment at the Fukushima Daiichi station an “urgent issue,” Abe ordered the government for the first time to get involved to help struggling Tepco handle the crisis.
The leak from the plant 220 km northeast of Tokyo is enough to fill an Olympic swimming pool in a week. The water is spilling into the Pacific Ocean, but it was not immediately clear how much of a threat it poses.

As early as January this year, Tepco found fish contaminated with high levels of radiation inside a port at the plant. Local fishermen and independent researchers had already suspected a leak of radioactive water, but Tepco denied the claims.

Tetsu Nozaki, the chairman of the Fukushima fisheries federation said he had only heard of the latest estimates of the magnitude of the seepage from media reports.

Environmental group Greenpeace said Tepco had “anxiously hid the leaks” and urged Japan to seek international expertise.

“Greenpeace calls for the Japanese authorities to do all in their power to solve this situation, and that includes increased transparancy…and getting international expertise in to help find solutions,” Dr. Rianne Teule of Greenpeace International said in an emailed statement.

In the weeks after the disaster, the government allowed Tepco to dump tens of thousands of tonnes of contaminated water into the Pacific in an emergency move.

But the escalation of the crisis raises the risk of an even longer and more expensive clean-up, already forecast to take more than 40 years and cost $11 billion.

The admission further dents the credibility of Tepco, criticised for its failure to prepare for the tsunami and earthquake, for a confused response to the disaster and for covering up shortcomings.
