| Title | Failure to Verify or Check the Adequacy of Design for Safety-Related Components with Four Examples |
| Description | The team identified a Green non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to verify or check the adequacy of design for with four examples. The licensee entered these issues into their corrective action program as ARs 1672459, 1676403, 1674790, 1675544 and 1679053, and performed evaluations to assure operability of components. The licensees failure to adequately perform engineering evaluations as described in the four examples was a performance deficiency. The performance deficiency was more than minor because it adversely affected the Mitigating Systems cornerstone attribute of Design Control and adversely affected the cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the deficiencies described above, resulted in a reasonable doubt that safety-related equipment could perform their functions under the most limiting conditions. In accordance with NRC IMC 0609.04, Initial Screening and Characterization of Findings , the inspectors conducted a Phase 1 Significance Determination Process (SDP) screening and determined the finding to be of very low safety significance (Green) because it was a design deficiency confirmed not to result in the loss of operability or functionality. Specifically, the licensee performed evaluations that provided reasonable assurance that the components would perform their required functions when called upon. The team determined that no cross cutting aspect was applicable to this performance deficiency because this finding was not indicative of current licensee performance. |
