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.

 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.
