| Title | Licensee-Identified Violation |
| Description | The licensee identified a NCV of the 10 CFR Part 50, Appendix B, Criterion III, Design Control of very low safety significance (Green) for the failure to ensure that tests on safety-related batteries D05, D06, D105, D106 and D305 were performed in accordance with Technical Specifications Surveillance Requirements (SRs). Point Beach Nuclear Plant SR 3.8.4.8 requires verification that battery capacity is greater than or equal to 80 percent of the manufactures rating when subjected to either a performance of modified performance discharge test. Surveillance Requirement 3.8.4.7 is modified by a note stating that it may also be satisfied every 18 months by the performance of 3.8.4.8. Contrary to the above, from March 15, 2007, the licensee failed to perform either SR 3.8.4.7 or SR 3.8.4.8 or declare LCO 3.8.4 not met due to not meeting the SRs. Specifically, on March 15, 2007, the licensee changed TS Bases for SR 3.8.4.8 which removed specific details for the performance of the modified performance testing of safety-related batteries. Prior to their removal from the TS Bases, the specific details for performing modified discharge tests were consistent with the guidance of IEEE 4501995; however, the licensee remained committed to the 1987 version of the IEEE standard which does not provide a method for performing modified discharge tests. Since the licensee remained committed to IEEE 4501987, the March 15, 2007 revision to the TS Bases were not screened as having an adverse consequence though the change to the Bases for SR 3.8.4.8 modified the requirements of the surveillance test and made the description of the testing more vague. Subsequently, maintenance procedures to perform the testing were revised and did not maintain the required specific battery profiles that would be necessary to meet the criteria of a modified discharge test. Consequently, since March 15, 2007, the licensee has taken credit for the performance of SR 3.8.4.8 in lieu of SR 3.8.4.7 without testing to the proper battery performance profiling. The licensee generated AR 01947039, 01950740 and 01952174 to address this issue. The inspectors determined that this issue was of very low safety significance (Green) after reviewing IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, dated July 1, 2012 and IMC 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, dated July 1, 2012. The inspectors answered NO to all questions in Exhibit 2, Section A, Mitigating SSCs and Functionality. Therefore, the finding screened as Green (very low safety significance). |
