| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion XI, Test Control, 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. The test program shall include preoperational tests. Test results shall be documented and evaluated to assure that test requirements have been satisfied. Contrary to the above, on February 8, 2006, January, 22, 2008, and May 30, 2009, the licensee failed to assure that test requirements were satisfied following replacement of turbine control valve fast closure pressure switches 1C71N005A, 1C71N005B, and 1C71N005C, respectively. Specifically, on each occasion, the licensee failed to identify that RPS response time testing was required by TSSR 3.3.1.1.17 prior to declaring these pressure switches operable and returning them to service. This resulted in the licensee operating at conditions where these pressure switches were required without assurance that the components were operable. Each of the pressure switches was subsequently satisfactorily tested as directed by the surveillance frequency of TSSR 3.3.1.1.7. The licensee performed an apparent cause evaluation and determined that this required post-maintenance test was not included in the work instructions because its post-maintenance testing procedures did not identify this test as a required test following the maintenance activity. The licensee revised its post-maintenance testing procedures to address this test. The inspectors determined that this violation was associated with a licensee-identified finding of more than minor safety significance because, had the post-maintenance testing procedures not been updated to include RPS response time testing as a required post-maintenance test for these pressure switches, switches that received maintenance could be returned to service with unsatisfactory RPS response times. The inspectors determined that this violation was of very low safety significance (i.e., Green) because when the licensee subsequently performed RPS response time testing for these pressure switches, the results were satisfactory. This violation is being treated as a non-cited violation consistent with Section 2.3.2 of the NRC Enforcement Policy. The licensee entered this violation into its corrective action program as AR 01258051. The licensee submitted LER 05000461/2011-003-00 on October 13, 2011, to report this issue as a condition prohibited by TS. Refer to Section 4OA3.1 of this inspection report for the review and closure of the LER. |
