EVENT DESCRIPTION

During the perfonnance of OP-4217, " Charging System Operability Test", Attachment A, on Number 2 charging pump failed to meet its Technical Specifications Surveillance Requirments (4.1.2.6.b) in that the pump's discharge pressure was not equal to or greater than 30 psig above main coolant pressure. This was the first occurrence

- of this problem. Proposed Change Number 147 was initiated to j

eliminate the pressure requirement and only use the minimum flow requirenent.

(LER 77-04/03L)

I CAUSE DESCRIFFION The surveillance rbquiirements 'kere based on the charging pumps being a centrifugal instead of the existing reciprocating type pump.

During the review of the Technical Specifications prior to implementation this fact was not co:npensated for. Acceptance of Proposed Change 147 will correct this problen.
