CAMP PENDLETON, Calif. (AP) — Workers have installed inspection equipment inside a reactor at the San Onofre nuclear power plant to help find a leak.
U-T San Diego (http://bit.ly/xW4ePg ) says the reactor cooled down enough on Monday for the equipment to be installed.
Unit 3 of the San Diego County plant was taken offline a week ago after a leak was detected in a tube that carries radioactive water in a steam generator.
Owner Southern California Edison says a tiny amount of radiation could have escaped into the atmosphere but no one was endangered.
The utility also has found unusual, premature wear found on hundreds of similar tubes in a twin reactor called Unit 2. That reactor is still in service while the tubes are plugged.
