Leak at San Onofre Nuclear Plant
The Los Angeles Times reported  yesterday:
Officials at the San Onofre nuclear power plant shut down one of the facility’s two units Tuesday evening after a sensor detected a possible leak in a steam generator tube.
The Orange County Register pointed out :
After an unplanned, precautionary shutdown of a reactor at the San Onofre nuclear plant Tuesday , a plant spokesman said Wednesday that a possible leak in one of the reactor’s steam generator tubes could have resulted in a tiny release of radioactive material into the atmosphere.
AP notes  today:
A tiny amount of radiation could have escaped into the atmosphere from a Southern California nuclear power plant after a water leak prompted operators to shut down the reactor as a precaution, officials said Wednesday.
Nuclear Regulatory Commission spokesman Victor Dricks said radioactive gas “could have” escaped the San Onofre Nuclear Generating Station on the northern San Diego coast.
The leak occurred in equipment that was installed in the plant in the fall of 2010. The leak occurred in one of thousands of tubes that carry radioactive water from the Unit 3 reactor.
However, the company has found damage to other tubes, Dricks said.
“The damage that they have found to many other tubes is unusual, and they are attempting to identify the reason,” Dricks said.
While the nuclear operator – Southern California Edison – says that only a tiny amount was released, and would pose no health problems, that’s what operators always say after a nuclear accident .
