PG&E reduces power at California reactor for maintenance

Washington (Platts)--13 Mar 2017 457 pm EDT/2057 GMT


Pacific Gas & Electric said Monday it had reduced power at Diablo Canyon-2 to 50% of capacity to undertake a planned cleaning of the reactor's intake tunnels.

Early that morning, the 1,197-MW reactor in Avila Beach, California, was at 85% of capacity, down from 100% the day before, according to US Nuclear Regulatory Commission reactor status reports.

Ed Halpin, PG&E senior vice president and chief nuclear officer, said in a statement Monday that the utility "will work throughout the week, and around-the-clock, to safely perform this work and then methodically return Unit 2 to full power."

During a normal operating cycle at the two-reactor Diablo Canyon station, "it is common for crews to perform a planned cleaning of the plant's cooling water system components -- such as the intake tunnels -- and to perform other scheduled maintenance," the statement said.

The 1,197-MW unit 1 continues to operate at 100% of capacity, it said.
