Diablo Canyon Power Plant Concludes Planned Maintenance and Refueling Outage on Unit 1

March 25, 2019

AVILA BEACH, Calif. — Operators at Pacific Gas and Electric Company’s (PG&E) Diablo Canyon Power Plant (DCPP) have safely returned Unit 1 to 100 percent power following a planned refueling and maintenance outage that began in early February.

"With safety as our core value, the men and women of Diablo Canyon safely and successfully completed more than 12,000 work activities during this outage. The work they have done 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, Vice President of Nuclear Generation and Chief Nuclear Officer.

During the planned outage, 12 major projects – involving approximately 160,000 person-hours – were safely completed. This work included replacing a portion of the reactor fuel, performing maintenance, and testing systems and components that are not accessible during normal plant operations.

Each of Diablo Canyon Power Plant’s two reactor units is safely refueled approximately every 20 months. Unit 2 is safely operating at 100 percent power, and will undergo a planned refueling outage in the fall of 2019.
