Pacific Gas and Electric Co. (PG&E, NYSE: PCG) has announced that Unit 1 at Diablo Canyon nuclear power plant in Avila Beach, Calif. returned to full power on June 22 after a planned maintenance and refueling outage that began on April 23.
During the outage, employees and contractors performed more than 225,000 hours of inspections, maintenance and project work, including replacing a portion of the reactor fuel and installing a new digital process control system (PCS).
The PCS monitors and controls various systems and provides indications for the control room. The project upgraded the PCS from analog to digital, which increases redundancies for safety, reduces maintenance and further enhances PG&E’s continued safe operation of the facility. Diablo Canyon is the first nuclear facility in the country to execute a PCS replacement of this extent.
Diablo Canyon Power Plant is a nuclear power facility owned and operated by PG&E. Its two units together produce approximately 2,300 MW.
