Diablo Canyon power plant begins scheduled maintenance and refueling outage on unit 2

Planned outages provide a major economic boost to the San Luis Obispo region; More than 1,000 supplemental workers brought in to help with plant improvements

October 6, 2014

AVILA BEACH, Calif.– Pacific Gas and Electric Company (PG&E) today announced that Unit 2 at Diablo Canyon Power Plant was safely shut down on Sunday, Oct. 5, 2014 for a scheduled refueling and maintenance outage.


In total, nearly 120,000 person-hours will be invested to enhance the operation of Unit 2 and to meet PG&E’s commitment to provide safe, affordable, reliable and emissions-free electricity through Diablo Canyon Power Plant.


During the outage, more than 1,000 highly-trained supplemental workers from around the country will provide a major economic boost to the San Luis Obispo region as they lodge in hotels and shop at local businesses, while working with PG&E employees to conduct thorough safety inspections and complete general plant improvements to enhance electric reliability.


"Diablo Canyon plays a major role in helping PG&E safely generate and deliver to its customers some of the nation's cleanest electricity," said PG&E Senior Vice President and Chief Nuclear Officer Ed Halpin. "Preparation for the thousands of activities our team will perform has been ongoing for more than a year. The refueling outage and equipment upgrades will ensure the continued safe and reliable operation of Diablo Canyon and provide an important economic boost to the communities in which our employees live and our company serves."


Major work to be performed includes replacing a portion of the Unit 2 reactor fuel, performing maintenance and testing on systems and components that are not readily accessible during regular plant operation. Similar work was performed on Unit 1 during a planned refueling outage earlier this year.


Each of Diablo Canyon Power Plant’s two reactor units is safely refueled about every 18 months. Unit 1 will continue to safely generate electricity while Unit 2 is offline.
