Xcel Energy agreed to take corrective measures to address the improper testing of welds on six spent fuel canisters at the Monticello, MN, nuclear plant, said officials at the Nuclear Regulatory Commission (NRC).
An NRC inspector saw two contractors fail to properly perform the examinations in 2013. The NRC also said the testing examinations ended up falsely recorded, and the plant failed to have effective quality controls in place to monitor the work.
The NRC found the contractors’ actions were deliberate and put the plant in violation of agency requirements.
The statement said the NRC found no immediate safety concerns with the canisters.
However, it did say Xcel agreed to take actions to come back into compliance, and to make a presentation on the lessons learned at an industry forum.
