"Utility is hoping to bring Unit 2 back into service at 70% capacity for five months before taking it offline for further inspections."
"Southern California Edison asked federal regulators Thursday for permission to restart one reactor at the shuttered San Onofre nuclear plant, but the plant will not return to full power in the near future.
The proposal comes eight months after the plant was powered down over safety concerns when a small amount of radioactive steam was released from one of the plant's generator tubes.
The leak led to the discovery of wear on thousands of tubes that carry water that transfers heat from the reactor core to generate electricity. The steam generators were newly replaced and had been operating for less than one year in one of the reactors, Unit 3, and less than two years in Unit 2.
The U.S. Nuclear Regulatory Commission ordered Edison to keep the plant shut down until it could pinpoint the cause and determine how to address it."
