Edison submitted a report to the Nuclear Regulatory Commission.

The plant on the Pacific Ocean hasn't produced power since Jan. 31 because of excessive wear in its reactors, and it's not clear when, or if, it will return to service.

The utility is working on plans to restart the nuclear plant, but opponents claim the facility is unsafe, is no longer needed and should be shuttered.
