At the December 17, 1993 meeting, the NRC staff questioned representatives.of Houston Lighting and Power (HL&P) about the analysis performed on the

! essential chilled water (ECW) system. Topics of discussion included: the-l licensee's engineering analysis for chiller operation under low heat load

! accident conditions; the need and scope of baseline testing of the ECW system that would more closely simulate design basis accident heat load conditions and validate operability; and, the need and scope of periodic testing of the i ECW system to ensure that it can perform its safety function.

HL&P discussed with York Corporation, prior to the meeting, the validity of l the MC6428 ECW chiller calculation. The licensee agreed to provide the NRC l with a letter from York Corporation regarding the chiller calculation, as well  !

as a copy of the appropriate test procedure and the unreviewed safety question )

evaluation for this modification.  !
