Re-Starting Kashiwazaki-Kariwa Nuclear Power Plant

New TEPCO leaders to push restarts of reactors in Niigata. June 29. KENTARO UECHI

"The new management leaders of Tokyo Electric Power Co. showed a bit of apprehension but still plan to restart reactors at the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture....

...TEPCO’s business reconstruction plan drawn up in May says the utility will have the Kashiwazaki-Kariwa reactors back online from April 2013."



2002 Scandal shut downs

The reactors at the KK plant were shut down one by one after the discovery of deliberate falsification of data. The first one was taken offline September 9, 2002, and the last one was taken offline January 27, 2003.[4] The newest units, the more inherently safe ABWRs, were taken back online the quickest and suffered the smallest effect. Units  1, 2, and 3 on the other hand, generated no electricity whatsoever during the entire fiscal year of 2003.

All reactors continue to use low-enriched uranium as the nuclear fuel; however, there have been plans drafted by Tepco to use MOX fuel in some of the reactors by the permission of the Japanese Atomic Energy Commission (JAEC). A public referendum in the Kariwa village in 2001 voted 53% against use of the new fuel. After the 2002 Tepco data fabrication scandals, the president at the time, Nobuya Minami, announced that plans to use the MOX fuel at the KK plant would be suspended indefinitely.
