Anti-nuclear activists are calling on a federal court to revisit safety decisions for Diablo Canyon Nuclear Power Plant in San Luis Obispo County.
Two nonprofit groups, Mothers for Peace and Friends of the Earth, submitted an appeal brief to the Ninth Circuit Court of Appeals this week. It accuses the Nuclear Regulatory Commission of making “unlawful” decisions when checking on the power plant’s safety operations.
“The NRC is responsible for ensuring that operation of nuclear reactors ‘provides adequate protection to the health and safety of the public,’” the brief read.
Linda Seeley with Mothers for Peace, claims the NRC neglected to check on an important piece of the power plant: its reactor pressure vessel.
“We decided to file the appeal because the reactor vessel is where the actual atomic reaction takes place,” Seeley said. “The Unit 1 reactor vessel at Diablo Canyon has not been inspected since 2003.”
Reactor pressure vessels are thick steel containers that hold nuclear fuel and keep radioactive material out of the environment, according to an NRC report.
The NRC declined KCBX’s request for comment due to the ongoing litigation.
But Suzanne Hosn, a spokesperson for the plant's operator, Pacific Gas and Electric, said in an email to KCBX, “all testing to-date has demonstrated that the reactor vessels for both Units 1 and 2 meet the NRC’s acceptance criteria.”
Hosn also said the reactor vessels at Diablo Canyon are held inside their respective containment domes, which are built on a 14.5-foot-thick concrete base built into bedrock.
Seeley said Mothers for Peace and Friends of the Earth are calling on the NRC to inspect the power plant further.
