Small fire breaks out at Diablo Canyon

A small fire broke out at Diablo Canyon nuclear power plant’s ocean intake structure Thursday evening. Firefighters quickly extinguished the blaze.

Shortly after 7 a.m., the motorized pump that runs a system to clean kelp and ocean debris in the ocean intake structure overheated, causing the fire, PG&E spokesman John Lindsey said in a tweet.

On-site firefighters responded and extinguished a small flame on the equipment that briefly flared up while they were at the scene, Lindsey tweeted.

Plant officials called for assistance from Cal Fire in line with Diablo Canyon procedures and out of an abundance of caution, Lindsey stated. The call for help from Cal Fire was canceled shortly afterwards.  Still, one Cal Fire engine assisted with mop-up.

Both nuclear reactors are continuing to operate. There is no risk to plant safety or Diablo Canyon workers, Lindsey said.

Investigators are still trying to determine what caused the motorized pump to overheat.
