LOS ANGELES (AP) -- The company that runs the troubled San Onofre nuclear power plant in California has taken another step toward trying to restart one of the twin reactors.
Southern California Edison, a unit of Edison Inernational, submitted paperwork to federal regulators Monday that would allow the Unit 2 reactor to run at 70 percent power, down from the now-required 100 percent.
The plant between Los Angeles and San Diego has been idle since January 2012, after a small radiation leak led to the discovery of unusual damage to tubes that carry radioactive water.
Edison says running at reduced power should end vibration that damages tubing.
The company wants to start the reactor in early June, to help meet summer power demand.
The Nuclear Regulatory Commission must approve a restart.
Anti-nuclear activists want the plant shut down permanently.
