The Hamaoka plant stops all operations for seismic risk

The Hamaoka nuclear power plant, 200 kilometers south of Tokyo, has completely ceased operations Saturday in the two reactors remained operational at the request of the Government, which is located in an area of high seismic risk. The operator of Hamaoka, Chubu Electric, stopped the reactions of fission reactor 5 in the early hours of the morning calls to insert control rods in the core, which stops the power generation process.

Yesterday, the company successfully stopped the unit 4, the first of only two remaining operational reactors at the plant in Shizuoka province, located in a junction of tectonic plates and a high risk of occurrence of an earthquake up to 8 degrees in the next 30 years. Chubu Electric, has been forced to bow to government demands that last week, in an unprecedented decision, requested that the plant was closed temporarily to avoid major risks after the nuclear crisis in central Fukushima, who suffered serious damaged by the earthquake of 9 degrees on March 11 in northeastern Japan.

Hamaoka, which was not affected by this devastating earthquake, had three more reactors of 1,000 megawatts of power, but only two were active, since the unit was under review three routine since November. Japanese Prime Minister, Naoto Kan, said yesterday that the temporary suspension was necessary Hamaoka, before expecting them to change the nuclear safety measures for the high probability of occurrence of an earthquake.

As the president said Japanese nuclear safety standards in Japan are reviewed by the consequences of nuclear accident in Fukushima, the most serious since Chernobyl in 1986.
