LOS ANGELES (AP) — The bill keeps climbing at California's troubled San Onofre nuclear power plant.
Southern California Edison has piled up $317 million in costs related to the long-running shutdown at the plant between Los Angeles and San Diego, which hasn't produced electricity since January.
Company documents Thursday show the bill for repairs and inspections has climbed to $96 million. With the plant out of service, replacement power costs have climbed to $221 million.
The problems center on four steam generators that were installed during a $670 million overhaul in 2009 and 2010. Tests found some tubes were so badly corroded that they could fail and possibly release radiation.
The company has asked federal regulators for permission to restart the Unit 2 reactor and run it at reduced power.
