Unit 1 at Diablo Canyon Power Plant was shut down Sunday for a planned refueling and maintenance outage.

PG&E says more than 12 major plant projects consisting of more than “150,000 person-hours” will take place during the outage.

Work will include replacing a portion of the reactor fuel, conducting maintenance, and testing systems and components that are not accessible during regular plant operations, according to PG&E.

“The work we are performing in the weeks ahead supports our strong commitment to operate DCPP in a safe and reliable manner and ensures the continued delivery of clean and affordable electricity to our customers,” said Jim Welsch, PG&E’s vice president of nuclear generation and chief nuclear officer, in a press release.

Unit 2 is up and running while unit 1 is offline.

PG&E says the reactors are refueled about every 20 months.

The work on unit 2 is scheduled for this fall.
