| Title | Inadequate Corrective Action for Non-Seismic Category 1 Piping |
| Description | The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to take adequate corrective actions regarding non-Category I (seismic) piping in the intake structure raw water vault. The licensees corrective actions for this issue involved isolating and removing the piping. The licensee entered this deficiency into their corrective action program for resolution as CRs 2013-04782, 2013-04956, 2013-09256, 2013-10626, and 2013-22090. The failure to take adequate corrective action regarding non-Category I (seismic) piping in the intake structure raw water vault is a performance deficiency. The performance deficiency was more than minor, and therefore a finding, as it is associated with the design control attribute of the Mitigating Systems Cornerstone and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, dated July 1, 2012, this finding was determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its allowed outage time, or two separate safety systems out-of-service for longer than their Technical Specification allowed outage time; and (4) did not represent an actual loss of function of one or more non-Technical Specification trains of equipment designated as high safetysignificance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of human performance associated with the decision-making component such that the licensee demonstrates that nuclear safety is an overriding priority. Specifically, that the licensee uses conservative assumptions in decision making and adopts a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate that it is unsafe in order to disapprove the action. |
