SUBJECT:
CLOSURE OF EMERGENCY CORE COOLING SYSTEM MINIMUM FLOW VALVES j
The enclosed Engineering Evaluation -is forwarded for your information and consideration. The report. concludes that not all, licensees may recognize the importance of minimum flow valves.to Emergency Core Cooling System pump-i operability.
It is recommended that AE00 suggest that the Office of-Inspection and Enforcement consider issuing an Information Notice to remind licensees of the importance'of minimum flow bypass capability as an essential pump protecticn feature and the dependency of ECCS pump operability on minimum flow' valve operability..It is als: suggested that the information notice l
emphasize that licensees review the control logic of the ECCS minimum flow valves to ensure that it is' adequate to satisfy containment isolation requirements, where' applicable.
