| Title | Licensee-Identified Violation |
| Description | The licensee identified a finding of very low safety significance (Green) and associated NCV of 10 CFR Part 50, Appendix B, Criterion XI, Test Control. Criterion XI requires, in part, that A test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Contrary to this requirement, on September 29, 2011, the licensee identified that they had failed to utilize a test program which incorporated all requirements from the applicable design documents to demonstrate that both EDGs would perform satisfactorily in service. Specifically, the test procedures being used by the licensee to demonstrate operability of the EDGs did not contain the correct load rejection testing requirements from the applicable design documents. As a result, the licensee determined that they had never demonstrated that they met load rejection surveillance requirement 3.8.1.7, and that both EDGs were inoperable. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems Cornerstone attribute of Procedure Quality and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Using IMC 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, the inspectors determined that the finding had very low safety significance because they answered No to all five questions contained in Column 2 of the Table 4a worksheet. The licensee developed new test procedures which included the appropriate acceptance criteria and test methodologies, satisfactorily tested both EDGs, and entered this issue into their CAP as AR 01305683, CDBI FSA-Question on Definition of Post Accident Load in TS and AR 1306107, largest post-accident load greater than in test OSP-ECC-0566. |
