The inspectors identified two examples of … The inspectors identified two examples of a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, regarding the licensees failure to follow the requirements of Procedure EN-OP-104, Operability Determinations. Specifically, for Condition Report CR-GGN-2012-09690, which documents an oil leak on the standby liquid control pump B, and for Condition Report CR-GGN-2012-09889, which documents degraded bolts on a flanged connection on standby service water B piping, the licensee failed to validate that operability evaluations completed for prior non-conforming conditions bounded the conditions documented in the new condition reports. As immediate corrective actions, the licensee re-performed the evaluations and established an adequate basis for operability for the conditions described in the two condition reports listed above. The licensee entered this issue into their corrective action program as CR-GGN-2012-09735 and CR-GGN-2012-10664. The finding was more than minor because if left uncorrected, not performing operability determinations in accordance with procedure could lead to a more significant safety concern. Specifically, if a condition renders a safety related system inoperable and because of this performance deficiency the licensee incorrectly determines that the system is operable, then this performance deficiency could result in a safety related system remaining inoperable for a long period of time. Using NRC Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, the inspectors determined that the issue affected the Mitigating Systems Cornerstone. In accordance with NRC Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings at Power, the inspectors determined that the issue has very low safety significance (Green) because although it affected the design or qualification of a mitigating system, the system maintained its operability. The finding had a cross-cutting aspect in the problem identification and resolution area, corrective action program component because the licensee failed to properly evaluate for operability conditions adverse to quality operability conditions adverse to quality
