"The Nuclear Regulatory Commission lays out steps that Southern California Edison must take before the troubled San Onofre plant will be allowed to come back on line."
"The U.S. Nuclear Regulatory Commission, citing serious concerns about equipment failures at the San Onofre nuclear power plant, has prohibited Southern California Edison from restarting the plant until the problems are thoroughly understood and fixed.
The plant has been shut down for two months, the longest in San Onofre's history, after a tube leak in one of the plant's steam generators released a small amount of radioactive steam. Since then, unusual wear has been found on hundreds of tubes that carry radioactive water.
Neither regulators nor Edison have said when they believe the plant will reopen. San Onofre is a major supplier of power for Southern California, producing about 2,200 megawatts of power, or enough electricity to serve 1.4 million households. It is Southern California's only nuclear power plant."
