June 27, 2017

AVILA BEACH, Calif. — Operators at Pacific Gas and Electric Company’s (PG&E) Diablo Canyon Power Plant today safely returned Unit 1 to 100 percent power – two weeks ahead of schedule – following a planned refueling and maintenance outage that began in late April.


"With safety as our core value, the men and women of Diablo Canyon safely and successfully completed more than 14,000 work activities during this outage. The work performed supports our continued commitment to generate safe, clean, affordable and reliable electricity" said Ed Halpin, Senior Vice President, Generation and Chief Nuclear Officer.


During the outage, more than 30 major projects – involving an estimated 157,000 person-hours – were safely completed. This work included replacing a portion of the reactor fuel, performing maintenance, and testing hundreds of 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.
