NRC: Fuel Transfers Can Resume At San Onofre NPP

The U.S. Nuclear Regulatory Commission said this week that spent fuel transfers could resume at the San Onofre Nuclear Generating Station in San Clemente, California.

San Onofre NPPFuel transfers were suspended after an August 3, 2018 incident in which a spent fuel canister became lodged in the flange of a guiding channel as it was being lowered into a vault. The canister did not drop, but it had the potential of falling 18 feet after it became stuck.

The NRC said it had reviewed the technical data from plant owner Southern California Edison that included detailed hypothetical outcomes based on what would happen to a scratched canister. 

San Onofre was permanently closed down in 2013 following premature wear found in replacement steam generators that had been installed in 2010 and 2011.
