A powerful warning siren for the San Onofre nuclear power plant blared a false alarm for nearly 20 minutes early Saturday morning, jarring residents awake and prompting a spate of worried telephone calls to local police. Authorities blamed the shrill dawn alarm on a malfunctioning siren that apparently was touched off when storm water seeped into the equipment.

An environmental group is deciding whether to appeal a state ruling that the San Onofre nuclear power plant does not appear to be violating its pollutant discharge permit. Earth Island Institute attorney Steve Crandall said Tuesday that the state Regional Water Quality Control Board "ignored" its own staff as well as the California Coastal Commission and a panel of scientists, which found that the San Onofre Nuclear Generating Station is damaging ocean habitat and fish populations.

The Nuclear Regulatory Commission has levied a $150,000 fine against Southern California Edison Co. for violations of safety requirements at the San Onofre nuclear power plant. The utility company said it will pay the penalty without protest and is in the process of correcting the "environmental qualification" violations in secondary support equipment and safety related equipment at the plant's Unit 1 reactor.

A high-decibel siren which is part of a public warning system for major accidents at the San Onofre nuclear power plant sounded by mistake Sunday, Southern California Edison Co. reported. David Barron, a company spokesman, said the siren near San Juan Creek Road and Camino Capistrano went off during the late afternoon and was reported to Edison about 5:30 p.m. by Orange County emergency management workers. By the time a repair crew reached the siren, it had stopped operating.

A nuclear power plant warning siren went off by mistake Sunday, scaring hundreds of residents who blocked an emergency phone system for 20 minutes, authorities said. The siren, one of 52 within a 10-mile radius of the San Onofre nuclear power plant, sounded at 1:12 a.m., letting out an undulating wail for 4 minutes and 28 seconds until its power was disconnected by a technician for the plant, said David Barron, a spokesman for Southern California Edison Co.

One of three nuclear reactors at the San Onofre nuclear power plant near San Clemente automatically shut down Friday after a reactor coolant pump failed. Southern California Edison, which operates the plant, said it believed that an electrical problem--perhaps a short--was responsible. There was no radiation release. The failure came five days after Edison restarted the 1,500-megawatt Unit 3 reactor after a 21-day shutdown to make minor repairs.
