Title | Inadequate Maintenance Procedure for the Service Water Pump Room |
Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1.a, associated with the inadequate Maintenance Procedures 7.2.15, Service Water Pump Column Maintenance and Bowl Assembly Replacement, Revision 35, Maintenance Procedure 7.2.16, Backup Fire Pump Maintenance , Revision 14, and Maintenance Procedure 7.2.30, Service Water Strainer Maintenance, Revision 19. Specifically, those procedures did not address the number of required temporary heaters and required power sources during a loss of offsite power during design basis cold weather temperature of -5 degrees Fahrenheit with service water pump room hatches removed or doors open during maintenance. The issue was entered into their corrective action program for resolution as Condition Reports CR-CNS-2012-07891, CR-CNS-2012-08184, and CR-CNS-2012-08371. The licensees inadequate procedural direction to establish temporary heating in the service water pump during cold weather condition with the hatches removed or doors open, was a performance deficiency. This performance deficiency was determined to be more than minor, and is therefore a finding, because it was associated with the procedural quality attribute of the Mitigating Systems Cornerstone, in that the inadequate procedures did not identify the number of temporary heaters and their power supplies that would be necessary to maintain the service water system operable/functional during a loss of offsite power coincident with the licensing basis cold weather conditions, and thereby affecting the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, Checklist 7, BWR Refueling Operation with RCS Level > 23\', and determined that the finding is of very low safety significance (Green) because the finding did not require a quantitative risk assessment because adequate mitigating equipment remained available and the finding did not constitute a loss of the diesel generator capable of supplying one division of the onsite safety related power distribution subsystems, as defined in Appendix G. The finding was determined to have a cross-cutting aspect in the area of problem identification and resolution, associated with the corrective action program, in that the licensee failed to thoroughly evaluate an independent heating system. |
