LOS ANGELES - Federal regulators have pushed back indefinitely a decision on the proposed restart of the troubled San Onofre nuclear power plant in California.
The Nuclear Regulatory Commission has delayed several earlier dates.
But its website on Monday listed no date for a restart ruling -- only "to be determined."
Agency spokesman Victor Dricks had no comment.
The plant between Los Angeles and San Diego hasn't produced power since January 2012, after a small radiation leak led to the discovery of unusual damage to hundreds of tubes that carry radioactive water.
Operator Southern California Edison wants permission to restart the Unit 2 reactor and run it at reduced power in hopes of stopping vibration blamed for damaging tubing.
