The inspectors identified a finding of very-low safety significance (Green), and associated Non-Cited Violation (
NCV) of Title 10 of the Code of Federal Regulations (CFR), Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to establish measures to assure that Environmental Qualification (
EQ) requirements for qualified components correctly translated into procedures and instructions. Specifically, the inspectors identified two examples of the licensees failure to ensure that the
EQ requirements for O-ring installed in
EC290 connector/plug-in cable assemblies were translated into the associated maintenance procedures and instructions(i.e.,
EQ Files, warehouses storage requirements). The licensee failed to correctly establish an end-of-life replacement schedule for the O-ring used in the cable assemblies installed in the dry well and failed to establish a 2-year shelf-life for the O-ring stored in the warehouse.
