Schwencer, Chief Licensing Branch No. 2 Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Subject:

NUCLEAR PROJECT NO. 2 OPERATING LICENSE NPF-21 RE(VEST FOR LICENSE AMENDMENT

Reference:

Letter, G02-84-032, GC Sorensen (SS) to A. Schwencer (NRC), Same Subject, Dated January 20, 1984 This is to confirm information provided R. Auluck, F. Churney, and R. Li of your staff in a telephone conversation April 10, 1984. The WNP-2 systems having high pressure/low pressure interfaces have the following features:

o Low pressure system injection valve open permissives have been modified to actuate on low reactor pressure rather than delta pressure across the valves; o High/low pressure interface valve leakage pressure monitor alarms are available in the Hain Control Room which are surveillance tested periodically; o Position indication on each interface valve is avai lable in the Control Room; and o Narrow range suppression pool level indication is available which is sufficiently sensitive to detect gross system leakage.

These features are similar to that provided by LaSalle Unit 1 which justified the same changes to the applicable LaSalle Unit 1 Technical Specification.

This( information is provided to expedite review of the Technical Specification Chan)e Request to Specification 3.4.3.2 requested in the reference letter.

Very truly yours, G. C. Sorensen, anager Regulatory Programs GCS:PAP:lp cc: R Auluck - NRC 8404l80147 8404l0 WS Chin -QPA PDR ADDCK 05000397 D Hoffman - NRC P PDR AD Toth - NRC Site
