Diablo Canyon 1 returns to full power after repair

PG&E (NYSE:POG) subsidiary Pacific Gas & Electric said Oct. 17 that it has fixed the feed-water pump issue at the Diablo Canyon 1 nuclear unit in California and returned the reactor to 100% power.

Diablo Canyon 1 had been at 50% power while the company diagnosed and fixed the feed-water pump issue. Diablo Canyon Unit 2 remains running at 100%.

 Diablo Canyon 1 and 2 are both roughly 1,100-MW pressurized water reactors (PWRs) located in San Luis Obispo County, Calif.

After Edison International (NYSE:EIX) subsidiary Southern California Edison decided to retire the San Onofre Nuclear Generating Station (SONGS) earlier this year, Diablo Canyon is now the only nuclear plant in California.

Diablo Canyon Units 1 and 2 are currently licensed to run through 2024 and 2025 respectively. Diablo Canyon had actually started the process for seeking a 20-year license extension for each unit in 2011 when the Fukushima disaster occurred in Japan.

Diablo Canyon then suspended its pursuit of the license renewals while it commissioned an in-depth study on seismic issues in the region.

Due to the recent federal government shutdown, the Nuclear Regulatory Commission (NRC) called off an Oct. 16 performance assessment for the nuclear plant
