Title | Failure to Adequately Dedicate a Commercial Grade Item for Safety Related Use |
Description | A Green self-revealing finding of very low safety significance and associated NCV of 10 CFR 50, Appendix B, Criterion VII, Control of Purchased Material, Equipment, and Services, was identified for the failure to adequately dedicate a commercial grade item for use in a safety-related application. The vendor supplied a mismatched stem and locknut in a valve rebuild kit which was procured as a commercial grade item and dedicated by the licensee for use in a safety-related application. The valve later failed when the locknut fell off the stem which caused the system to be inoperable. The finding was determined to be more than minor because the finding was associated with the design control attribute and affected the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was determined to be of very low safety significance from a Phase 1 SDP because it only affected the loss of function of one division of non-interruptible air supply system (NIAS) for less than the Technical Specification allowed outage time. There were no cross-cutting aspects associated with this finding since the deficiency was not reflective of current licensee performance |
