US Nuclear Regulatory Commission expert says Diablo Canyon nuclear power plant should be shut down

In an internal report that was released August 25, NRC senior federal nuclear expert Michael Peck called for Pacific Gas and Electric’s Diablo Canyon NPP to be shut down pending a safety review. At issue is the recently discovered Shoreline Fault. However, the other three faults, including the Hosgri Fault, reportedly responsible for a devastating earthquake in Santa Barbara in the 1900’s, are also issues.

Here is a petition by Friends of the Earth to shut down Diablo Canyon:

Last year, the Union of Concerned Scientists released a report on Diablo Canyon. They found the NRC was not holding Diablo Canyon to the same earthquake safety standards as other nuclear power plants.

This is a dangerous double standard,” said David Lochbaum, director of UCS’s Nuclear Safety Project and author of the report. “At other facilities, the NRC enforced its safety regulations and protected Americans from earthquake threats. Today, in the case of Diablo Canyon, the NRC is ignoring its regulations, unfairly exposing millions of Americans to undue risk.”

When similar concerns surfaced at nuclear facilities in California, Maine, New York, Pennsylvania and Virginia, the NRC did not allow the plants to continue to operate until the agency determined they met safety regulations…In contrast, the NRC has allowed PG&E to continue to operate Diablo Canyon’s reactors despite this known threat.

Peck first raised his concerns in September 2010 when he filed non-concurrence papers and later elevated them to differing professional opinion, the highest level of official dissent within the agency. His report said that pipes and other important plant equipment at the plant may not be able to withstand the maximum shaking that could be generated by the Shoreline fault, which runs 2,000 feet offshore of the plant.

“We find it completely disgraceful that the NRC hid these concerns for all these years,” said Jane Swanson, spokeswoman for the antinuclear group San Luis Obispo Mothers for Peace.

Peck recommended that Diablo Canyon be shut down until it can be proved that the plant could withstand a quake along the Shoreline fault, a process that could require an amendment to the plant’s current operating license.

According to Peck’s filing, PG&E research in 2011 determined that any of three nearby faults – the Shoreline, Los Osos and San Luis Bay – is capable of producing significantly more ground motion during an earthquake than was accounted for in the design of important plant equipment. In the case of San Luis Bay, it is as much as 75 percent more.

On August 26, Friends of the Earth filed a formal petition with the NRC:

Friends of the Earth — an advocacy group critical of the nuclear power industry — filed a petition with the Nuclear Regulatory Commission asking for a hearing and charging the Diablo Canyon plant is violating its operating license.

… The group argues the reactors located between Los Angeles and San Francisco should remain closed until a rigorous safety review is completed and PG&E amends its federal license.
