Dear Mr. Powers:
s Furthermore, the bases section is being clarified to describe why the injection rather than the recirculation mode during flow balancing is the minimum'resistance and, consequently, more conservative configuration for runout considerations.

Notice Enclosed is a copy of a "Notice of Consideration of Issuance of Amendment to Facility Operating License, Proposed No Significant Hazards Consideration Determination, and Opportunity for a Hearing," related to your request for a license amendment dated September 14, 1998. These amendments would change the runout limits for a safety injection (Sl) pump to 675 gallons per minute (gpm), unless the pump is specifically tested to a higher flow rate, not exceeding 700 gpm for both Units 1 and 2. This change was initiated upon reevaluation of correspondence from Westinghouse sent to the licensee in 1991, which indicated that the generic runout limits for Pacific 2" JTCH pumps was 675 gpm unless each specific pump is tested to a higher flow rate.
Individual testing is necessary due to test variations between pumps which may limitthe applicability of testing of one pump to another pump due to manufacturing tolerances in the sand cast impellers and material changes in the pump casing.
