SAN CLEMENTE, Calif. (KABC) -- New problems at the San Onofre nuclear plant: Four more tubes that carry radioactive water have failed pressure tests, bringing the total number to seven.

A special team of federal inspectors was called to the San Onofre Nuclear Generating Station just south of San Clemente after seven tubes that carry radioactive water failed pressure tests this week, according to officials.

The steam generator tubes are located inside the plant's Unit 3 reactor. The reactor was shut down late January after a leak was found.

"It's kind of frightening when they're failing, especially living in a beach community this close to San Onofre," said San Clemente resident Tom Eikmeier.

Small traces of radioactive gas escaped during the leak in January, but officials with Southern California Edison (SCE), the company that runs the plant, said there was no danger to workers or residents.
