We previously reported a potential 50.55 (e) item (M-13) involving accelerated wear of service water pump impellers. 1:?is letter will advise you that after detailed investigations we hate concluded this matter is definitely reportable under 50.55 (e) .
A detailed report of our investigations, conclusions and system modifications required is being included in an FSAR revision which will be forwarded to you shortly.
The matter can be summarized as follows: The service water pumps were designed to 4ccommodate maximum service water flows associated with worst. case LOCA situations. Service water flows during normal non-accident conditions are less than that required to prevent internal recirculation in the pumps. The original design made no provision to assure that internal recirculation would not occur and we believe it did occur during initial pump operation. The. accelerated impeller wear is attributed to internal recirculation.
Flow elements and minimum flow control valves are being added to the service water system to assure the situation will 1
