Nuclear Energy & Nuclear Issues

Nuclear Energy In California

In 2010, nuclear provided almost 14 percent of the entire California power mix (which includes out of state imports). As of mid-2012, California had one operating nuclear power plant: Diablo Canyon (2,160 megawatts), near San Luis Obispo. The plant's nuclear units use ocean water for cooling.

The San Onofre Nuclear Generating Station (SONGS) (2,150 megawatts), about midway between Los Angeles and San Diego, went offline in January 2012 and was ordered by the Nuclear Regulatory Commission to stay offline while tubing wear issues were investigated. Subsequently, plant owners announced in June 2013 that remaining Units 2 and 3 would be permanently retired.

Oversight for nuclear energy rests with the U.S. Nuclear Regulatory Commission, which regulates U.S. commercial nuclear power plants and the civilian use of nuclear materials.
