| Title | Components of Indeterminate Quality Installed in Safety-Related Applications |
| Description | The team identified a Green non-cited violation of 10 CFR 50, Appendix B, Criterion III, Design Control, for the licensees failure to control deviations from quality standards. After identifying that maintenance personnel had failed to ensure that subcomponents of 480-volt switchgear were properly identified and controlled during refurbishment, the licensee failed to document or evaluate where subcomponents of an indeterminate pedigree had been installed in safety-related applications. The licensee took immediate action to confirm the operability of the installed trip units and to determine the scope of the problem. The failure to control deviations from quality standards as required by 10 CFR 50, Appendix B, Criterion III was a performance deficiency. This performance deficiency was more than minor because it affected the design control attribute of the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of components that respond to initiating events. Using Inspection Manual Chapter 0609, Appendix A, the team determined that the finding was of very low safety significance because it did not result in the loss of operability or functionality of a safety-related system or train. The finding had a cross-cutting aspect in the corrective action program component of the problem identification and resolution cross-cutting area because the licensee had failed to implement a corrective action program with a low threshold for identifying issues to ensure that an issue potentially affecting nuclear safety was promptly identified and fully evaluated. |
