The San Onofre Nuclear Plant has been idle since Tuesday afternoon when a potential leak was discovered in one unit. The other unit was already offline for maintenance and refueling.
Edison said the possible leak and small radiation leak created no safety threats and that ample power reserves existed to cover electric demand. The Company did not report when Tuesday’s problem would be fully diagnosed and repaired.
During maintenance on the other reactor a large number of tubes were found to have advance wear, according to the LA Times. Edison is still analyzing the premature wear to determine which tubes would require repair or replacement.
