LOS ANGELES — The integrity of some equipment installed in 2009 at Southern California’s San Onofre Unit 2 nuclear plant is drawing concern after unusual wear was found on hundreds of tubes that carry radioactive water.

Thursday’s 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.
