SUBJECT:

REVIEW OF VITAL AREAS FOR WASHINGTON PUBLIC POWER SUPPLY SYSTEM - NUCLEAR PROJECT 2 By memorandum dated September 19. 1983, you requested our review of Section 4.0 - Vital Area Identification of the Safety Evaluation Report (SER) prepared by NMSS for the Washington Public Power Supply System - Nuclear Project 2 (WNP-2). Subsequent to your request, a meeting between the NRR and NMSS staff was held concerning vital area identification. During that meeting, it was agreed that ASB would review the NMSS SER for information only and would not apply any vital area identification criteria beyond the present requirements of 10 CFR 73.55. In accordance with that agreement, we have reviewed the WNP-2 vital areas and have identified no concerns related to meeting 10 CFR 73.55 requirements. However, the Appentiix which identifies the vital areas needs some clarification. The Appendix states that the suppression pool is the ultimate heat sink. The suppression pool is a long-tem water source but the ultimate heat sink is the spray pond.
