San Onofre nuclear plant may have been sabotaged

Security has been beefed up at the San Onofre nuclear power plant in Southern California after it was discovered that a generator there might have been tampered with, the plant operator said. The plant has been out of service since January due to a leak in a steam generator.

Southern California Edison said it discovered engine coolant in an oil system in the backup diesel generator in late October during routine monitoring. An internal probe found evidence of potential tampering, though it could not be confirmed.
