Pinnacle Shuts Palo Verde 3 Reactor for Unplanned Valve Repairs

Pinnacle West Capital Corp. shut the 1,335-megawatt Palo Verde 3 reactor in Arizona to make unplanned repairs to a valve in a containment building.

“We’ve had this valve under surveillance and knew we would have to bring the unit down to make repairs at some point,” Betty Dayyo, a plant spokeswoman based in Phoenix, said by phone. “The problem is a steam leak.”
