AVILA BEACH, Calif., March 28, 2013 /PRNewswire/ -- Unit 2 at Pacific Gas and Electric Company's (PG&E) Diablo Canyon Power Plant is running at full power again following a planned maintenance and refueling outage that began Feb. 3.
The outage was among the most successful in Diablo Canyon's history, given the depth and breadth of the work involved, the excellent employee safety performance, and its conclusion ahead of schedule. Unit 1 continued to reliably generate electricity throughout the Unit 2 outage.
"Diablo Canyon Power Plant plays a major role in helping PG&E deliver some of the nation's cleanest electricity to its customers," said PG&E Senior Vice President and Chief Nuclear Officer Ed Halpin. "The work performed during this and other planned outages supports our safe operation of the facility, and ensures a steady flow of affordable, reliable and carbon-free energy to more than three million Californians."
About 30 projects were completed during the 48-day window, in addition to standard maintenance. Crews performed about 12,000 outage-related activities, involving about one million hours of inspections, maintenance and equipment upgrades.Major project work included replacing a portion of the Unit 2 reactor fuel, upgrading a crane system that moves key plant components, and installing a new digital Process Control System (PCS). The PCS monitors and controls various plant systems. The Diablo Canyon team set an industry record by completing the upgrade, which involved thousands of electrical connections, in less than 50 days. Halpin attributed the success of the outage in part to effective preparation and planning by plant personnel. "Completing the outage in a safe and efficient manner and returning the unit to service ahead of schedule is a testament to the hard work and commitment of our dedicated employees and contractors—both before and during the outage," Halpin said. "When considering the scope of work conducted, our team of professionals turned in a world-class performance."
