Inspectors Find 'Unusual' Wear on Tubes at Calif. Nuclear Plant
"LOS ANGELES — Unusual wear has been found on hundreds of tubes that carry radioactive water at Southern California’s San Onofre Unit 2 nuclear plant, raising questions about the integrity of equipment the company installed in a multimillion-dollar makeover in 2009.
The disclosure came two days after a tube leak at the plant’s other unit prompted operators to shut down the reactor as a precaution. A tiny amount of radiation could have escaped, but officials say workers and the public were not endangered.
The problems at Unit 2 were discovered during inspections of a steam generator, after the plant 45 miles north of San Diego was taken off-line for maintenance and refueling. The two huge steam generators at Unit 2, each containing 9,700 tubes, were replaced in fall 2009, and a year later in its twin plant, Unit 3, as part of a $670 million overhaul."
