The nuclear power plant Ōi (Japanese大 饭 発 电 所, Ōi hatsudensho ) is a nuclear power plant in Japan. It is in the village in the district Ōi Ōi in Fukui Prefecture. The plant belongs to the Kansai Denryoku. It is also known by the alternative spellings or Ohi Ooi.

There are four pressurized water reactors on the site. Reactors 1 and 2 were supplied by Westinghouse, 3 and 4 from Mitsubishi. A fifth reactor block with an output of 1200 MW.

Incidents

On 5 May 2004, it was found that boric acid leaks from a valve of the reactor. On 22 December 2005 it was because of a hurricane to problems with the power lines. The power plant was taken as a precautionary measure by the network.

On 22 March 2006 it burned in the non-nuclear part of the plant, two workers suffered smoke inhalation.

On July 16, 2011 - about four months after the nuclear disaster at Fukushima - the reactor of Unit 1 of Ōi NPP was shut down. Reason is a loss of pressure in a boric acid container standing by for emergency situations, said the operator. When the reactor could go online again, is still unclear. After this cut-off, only 18 of the 54 Japanese commercial nuclear reactors were in operation.

History

On December 16, 2011, block 2, the last still producing reactor of the nuclear power plant Ōi was down for maintenance. 5 May 2012 provisionally went the last in Japan still ongoing nuclear reactor planned by the network, the reactor 3 nuclear power plant in Tomari.

Because of possible bottlenecks in the power supply in the summer, the Government issued on 16 June 2012, the permission, the Unit 3 and Unit 4 of the nuclear power plant Ōi boot again. Beginning of July 2012 came despite protests by the population of the reactor 3 is in operation.

In December 2012, it was announced that the plant is possibly on an active crevice.
