Diablo Canyon's Unit 1 back online

San Luis Obispo - The TribuneJuly 4, 2013 

One of Diablo Canyon Power Plant’s reactors, shut down June 26 because of a minor safety concern, was brought back online July 4, according to PG&E.

A minor leakage found on a section of pipe inside the containment building for Unit 1 was the reason for the June shutdown. The leak was found on a pipe that is part of the Residual Heat Removal System, which helps cool the reactor once it has been shut down.

Unit 1 started providing power to the state’s grid July 1 before it transitioned to full capacity July 4.

During the repairs, Unit 2 was online and providing power to the grid as usual.

The Avila Beach-based nuclear power plant’s two reactors produce about 2,300 megawatts, or about 10 percent of power produced in California.
