| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures and drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings. Instructions, procedures or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to the above, on October 24, 2012, the licensee failed to perform surveillance testing on the 22 Turbine Driven Auxiliary Feedwater (TDAFW) Pump (an activity affecting quality) with a procedure appropriate to the circumstance. Specifically, quantitative acceptance criteria contained in Surveillance Procedure SP 2102, 22 TDAFW Pump Monthly Test, was not updated to reflect a change in the baseline stroke time data for valve CV-31999, 22 TDAFW Pump Main Steam Supply Control Valve. As a result, CV-31999 failed to meet the procedurally indicated stroke time criteria. This required operations personnel to declare the 22 TDAFW pump inoperable. The inspectors assessed the significance of this finding using IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power. The inspectors determined that this issue was of very low safety significance (Green) because each of the questions contained in IMC 0609, Appendix A, Exhibit 2 could be answered no. Specifically, a loss of function did not occur because the actual valve stroke time met the revised baseline acceptance criteria. The licensee documented this issue as CAP 1356385. Corrective actions for this issue included issuing the revised surveillance procedure, performing an extent of condition review, and ensuring that procedures which required revisions to their acceptance criteria were quarantined until the procedure revision was approved. |
