| Title | Failure to Properly Inspect Service Water Pump Motor Lube Oil Heat Exchangers |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to adequately prescribe a procedure to inspect the service water (SW) pump motor lube oil heat exchangers (HXs) as committed to in the licensees Generic Letter 89-13 response dated January 31, 1990. Specifically, a review of SW pump motor lube oil HX inspection documents identified that the licensee was not inspecting the internals of the lube oil HXs and did not adequately implement other accepted performance monitoring methodologies. The issue was entered into the licensees corrective action program as condition report CR-12-00844. The inspectors determined that the failure to adequately prescribe a procedure to inspect the SW pump motor lube oil HXs was a performance deficiency (PD). The inspectors also reviewed Inspection Manual Chapter (IMC) 0612, Appendix B and determined the PD is more than minor and therefore a finding, because it adversely impacted the Mitigating Systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences and the respective attribute of procedure quality because inadequate monitoring of the HX performance would lead to a common mode failure mechanism that would adversely impact the safe operation of the SW pumps during severe environmental conditions. The inspectors performed a risk evaluation using IMC 0609, Appendix A, Phase 1, and determined the finding has very low safety significance (Green) because it was not a design deficiency, did not represent a loss of safety function and did not screen as potentially risk significant due to a seismic, flooding or severe weather initiating event. The cause of this finding did not involve a crosscutting aspect because it is not indicative of current licensee performance. |
