The first two units, Genkai-3 and Ikata-3, began operations with MOX fuel in November 2009 and March 2010 respectively. Use of MOX fuel in light-water power reactors is part of Japan's "pluthermal" program, which plans to have 16-18 reactors using MOX fuel by 2015.
Third reactor in Japan to use MOX fuel
The Tokyo Electric Power Co. began loading MOX fuel into Unit 3 reactor of its Fukushima-Daiichi power plant. The reactor will be the third unit in Japan to use MOX fuel. The reactor is expected to be back online on September 23, 2010.
