UNITED STATES NUCLEAR REGULATORY COMMISSION DOCKET NO. STN 50-495 STONE a WEBSTER ENGINEERING CORPORATION REFERENCE SAFETY ANALYSIS REPORT FOR SWESSAR-P1 BALANCE-0F-PLANT STANDARD DESIGN AND ITS RELATIONSHIP TO THE RESAR-41 STANDARD DESIGN NOTICE OF ISSUANCE OF AMENDMENT TO PRELIMINARY DESIGN APPROVAL Notice is hereby given that the staff of the Nuclear Regulatory Commission has issued Amendment No. 4 to Preliminary Design Approve.
No. PDA-4, dated August 18, 1979, for the reference system design of a balance-of-plant portion of a pressurized water reactor nuclear power plant utilizing the Westinghouse RESAR-41 nuclear steam supply systen design, and as described in the application by Stone & Webster Engineering Corporation (SWESSAR-P1). Preliminary Design Approval No. PDA-4 was issued by the staff of the Nuclear Regulatory Commission on May 5,1976.
The amendment extends the expiration date for Preliminary Design Approval No. PDA-4 from August 18,1979 to May 5,1981. This change was made as a result of the Nuclear Regulatory Comission's August 1978 policy statement on standardization of nuclear power plants which provided for an extension to five years of the effec'.ive terms for preliminary design approvals for reference system designs wnich previously were set to terminate three years after issuance.

. The Nuclear Regulatory Commission's August 1978 policy statement identified certain matters that PDA holders would be required to address prior to the granting of PDA extensions. These matters were identified in an NRC staff letter to the Stone & Webster Engineering Corporation, R. Boyd to W. Kennedy, dated January 24, 1979. By letters dated July 16, 1979 and August 17, 1979, W. Kennedy to R. Boyd, the Stone & Webster Engineering Corporation submitted Amendments 40 and 41, respectively, to the SWESSAR-Pl application, which addressed each of these matters.
The NRC staff has reviewed Amendments 40 and 41 for completeness and has concluded that the Stone & Webster Engineering Corporation has addressed each of these matters. The NRC staff considers this to be an acceptable basis for extending PDA-4 for two additional years. If the NRC staff is informed by a utility-applicant that it intends to reference the SWESSAR-Pl/RESAR-41 design after August 18, 1979, it will then per#orm a detailed review of Amendments 40 and 41 to assure that each of the f
identified matters has been acceptably resolved for the SWESSAR-Pl/RESAR-41 design.
.The NRC staff has implemented this procedure for extending PDA's, in consideration of the high degree of confidence it places in reference system designs for which PDA's have been issued.
This procedure permits the detailed review of the identified matters to be deferret on these designs until a utility-applicant requirement for that review is identified.
h
3 Amendment No. 4 to PDA-4 is effective as of its date of issuance and shall expire on May 18, 1981, unless earlier superseded by issuance of a final design approval for the SWESSAR-Pl/RESAR-41 design, or unless extended by the NRC staff.
The expiration of PDA-4, as amended, should not affect use of the SWESSAR-Pl/RESAR-41 design for reference in any construction permit application docketed prior to such date.
A copy of Preliminary Design Approval No. PDA-4, Amendment No. 4 dated August 18, 1979 is available for public inspection at the Commission's Public Document Room at 1717 H Street, N. W., Washington, D. C. 20555.
Dated at Bethesda, Maryland, this 18th day of August 1979.
