San Francisco, March 11, 2011 — In a move PG&E Corp. calls routine, the power producer has put its Diablo Canyon nuclear power plant on alert due to a tsunami warning in California.
Much of the West Coast is under a tsunami warning following the 8.9 magnitude earthquake in Japan that has sent tsunami waves across the Pacific Ocean.
The Nuclear Regulatory Commission said there is nothing wrong with the plant, but a tsunami warning requires the plant to remain on alert as a precaution. All units are still in service and operating normally.
The NRC said the plants are located in an area that the expected waves should not impact, and furthermore that the plants are designed to deal with the sort of waves heading for the California coast.
Both reactors at Diablo Canyon were operating normally and at full capacity.
The NRC also said Edison International's San Onofre nuclear plant was monitoring the tsunami but was only under a tsunami watch.
Diablo is located in the middle of the Californian coast, about halfway between Los Angeles and San Francisco. San Onofre is on the Southern California coast between Los Angeles and San Diego.
