(AP)—The future of the shuttered San Onofre nuclear power plant is clouded by uncertainty.
Regulatory filings disclosed Tuesday say it is contending with rising costs, extensive equipment repairs and even questions about insurance coverage for wildfires.
The documents released by Edison International, the parent company of San Onofre operator Southern California Edison, touch on a series of broad questions about the plant as SCE pushes to restart one of two reactors.
The company says costs for repairs and inspections jumped to over $400 million through December.
The plant hasn't produced electricity since January 2012, after a tiny radiation leak led to the discovery of unusual damage to hundreds of steam generator tubes that carry radioactive water.
