The US Nuclear Regulatory Commission (NRC) announced on 24 August that it will conduct a special inspection at the site of the San Onofre Nuclear Generating Station (Songs), after a near-accident occurred on 3 August during the transfer of highly radioactive used fuel. NRC inspectors will review what happened when a canister loaded with used fuel became jammed while being lowered into a storage vault. It narrowly avoided being dropped 18 feet. The incident was revealed during a community engagement panel by safety inspector David Fitch. Tom Palmisano, chief nuclear officer of Southern California Edison (SCE), described the event as “a serious near miss.”
