August 2, 1984 i Mr. Harold R. Denton, Director Docket No. STN-50 601 l Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555 SJBJECT: RAPWR RESAR-SP/90: Consolidation of PDA Modules 6 and 8 l 1

ATTENTION: K. T. Eccleston, Project Manager, SSPB Dear Mr. Denton

{

During the course of developnent of RESAR-SP/90 PDA Module 6, " Secondary Side j Safeguards System (SSSS)" and PDA Modale 8, "Stean and Power Conversion System" it has become apparent that in order to have a clear understanding of the ,

interrelationships between these two areas of the plant, and to avoid extensive cross-referencing, it.is advisable to consolidate these two modules into one <

integrated module. The resulting module entitled, " Integrated Modules 6 and 8:

SSSS/ Steam and Power Conversion System" will then contain a complete safety analysis report (SAR) Chapter 10 augmented by supporting information from other SAR chapters as appropriate. Enclosure 1 illustrates the approximate Table of Contents for the integrated module.

'Ihe Emergency Feedwater System will be located in SAR sub-section 10.4.9 (which is traditionally entitled " Auxiliary Feedwater"). A new sub-section,10.4.10, will be added entitled "Startup Feedwater System". Interface criteria for those areas of the plant outside the scope of the HAPWR Nuclear Power Block (e.g.,

detailed design criteria for the Startup Feedwater System, etc.) will be provided in an appendix to Chapter 10.

Mr. HJ 'R De6toit Page Two The current PDA licensing schedule targets Modules 6 and 8 for August and October 1984 sutxnittals, respectively. Instead, we plan to submit the consolidated module in September 1984.

Please cor. tact Mr. Douglas G. Bevard if you require any additional information relative to the Westinghouse planned module consolidation.

Very truly yours, f) ,
