Title | Inaccurate Minimum Low Head Safety Injection Flow Specified in Emergency Operating Procedure |
Description | The inspectors identified a finding of very low safety-significance and associated NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to specify the appropriate quantitative acceptance criterion to assure that adequate Emergency Core Cooling System flow would be delivered to the core following switchover to containment sump recirculation. This finding was entered into the licensees corrective action program. The finding was determined to be more than minor because the licensee failed to include the appropriate quantitative set-point value for the minimum low-head safety injection train flow following switchover to containment sump recirculation to assure sufficient reactor coolant was available. This finding is of very low safety-significance (Green) because it did not result in a loss of operability, did not represent an actual loss of safety function, and is not potentially risk-significant due to external events. The cause of this finding is related to the cross-cutting aspect in the area of Human Performance, Work Practices, because the licensee did not ensure proper supervisory and management2 Enclosure oversight of contractor work activities. Vendor calculations were used as the basis for an EOP set-point without taking into account specific plant design information such as instrument uncertainties, flow instrument calibration effects, and RHR minimum flow |
