SAN LUIS OBISPO, Calif. (AP) - Pacific Gas & Electric says it is considering appealing a Nuclear Regulatory Commission citation for a reactor cooling system problem at its Diablo Canyon nuclear power plant.
PG&E said in a statement Friday that its focus on safety led to discovery and repair of the problem.
The Tribune of San Luis Obispo (https://bit.ly/2hunJoH) says the NRC issued a “white finding” Thursday. That color-coding means the problem created a low-to-moderate safety risk.
In May, workers found that an emergency cooling system for one of the two reactors wasn’t working - and may not have been operating since it was last checked in October 2014. The problem was an improperly installed switch.
PG&E said it believes that if the system had been needed its operators would have successfully responded, and redundant cooling sources were available.
