Japan Has 2 Reactors With 4.6% of Total Capacity Online

February 20, 2012

Feb. 21 (Bloomberg) -- Japan has two nuclear reactors operating as of today with capacity of 2,268 megawatts, or 4.6 percent of the total, according to data compiled by Bloomberg.

Kansai Electric Power Co. halted the 870-megawatt No. 3 reactor at its Takahama nuclear plant in western Japan today for regular planned maintenance, Yusuke Inoue, a spokesman for the utility said by phone.

Reactors have been closed for maintenance, safety checks and stress tests following the March 11 earthquake and tsunami that caused uranium fuel meltdowns and radiation leaks at Tokyo Electric Power Co.’s Fukushima Dai-Ichi plant. The shutdown of the Takahama No. 3 reactor leaves Kansai Electric, the Japanese utility that relies the most on nuclear generation, with all its atomic power plants offline.

The following table shows the status of the 54 reactors with capacity of 48,960 megawatts operated by Japanese power companies. Capacity figures are in megawatts.
