Unit 1 at Diablo Canyon Undergoing Planned Maintenance

Pacific Gas and Electric Company (PG&E) today announced that operators at Diablo Canyon Power Plant safely took Unit 1 offline to replace electrical equipment and clean the plant’s intake tunnels, both of which are located on the non-nuclear side of the plant. 

During a normal operating cycle at Diablo Canyon, it is common for a unit to come off-line to clean cooling water system components – such as the intake tunnels – and to perform other scheduled maintenance.

Unit 1 will return to full power following completion of the work.  Unit 2 continues to safely operate at 100 percent power.
