PG&E taking Diablo Canyon 1 offline for repairs

Pacific Gas & Electric (PG&E) said Dec. 31 that it is taking Unit 1 of the Diablo Canyon nuclear plant offline as part of a planned outage to repair a feedwater heater on the non-nuclear side of the plant.

Diablo Canyon 2 continues to run at 100% power, the company noted. The two nuclear units in San Luis Obispo County, Calif., together can generate about 2,300 MW of carbon-free electricity, the company said.

Earlier on Dec. 31, Diablo Canyon 1 had been listed at 33% power on the Nuclear Regulatory Commission (NRC) daily reactor status report.

Both units are pressurized water reactors (PWRs) that were commissioned during the 1980s.
