UNITED STATES NUCLEAR REGULATORY COMMISSION DOCKET N0. STN 50-480 WESTINGHOUSE ELECTRIC CORPORATION REFERENCE SAFETY ANALYSIS REPORT (RESAR-41 NUCLEAR STEAM SUPPLY SYSTEM STANDARD DESIGN)
NOTICE OF ISSUANCE OF AMENDMENT TO PRELIMINARY DESIGN APPROVAL Notice is hereby given that the staff of the Nuclear Regulatory Commission (NRC staff) has issued Amendment No. I to Preliminary Design Approval No. PDA-3, dated Decembe-28, 1978, for the reference system design of a nuclear steam supply system portion of a pressurized water reactor nuclear power plant as described in the Westinghor: Dectric Corporation Reference Safety Analysis Report RESAR-41 and amendments ther eto.
PDA-3 was issued by the NRC staff on December 31, 1975 for a three-yet.r period.
Amendment No. I to PDA-3 extends its expiratior, date from December 31, 1978 to December 31, 1980.
This change was made as a result of the Nuclear Regulatory Commission's August 1978 policy statement on standardization of nuclear power plants which provided for an extension to five years of the effective terms for preliminary design approvals for reference system designs issued prior to the August 1978 policy statement. Previously, the preliminary design approvals for nuclear steam supply system reference system designs were set to terminate three years after issuance.
79011200[,2.
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 Westinghouse Electric Corporation, R. Boyd to T. Anderson, dated November 9, 1978. By letters dated December 15, 1978 and December 27, 1978, T. Anderson to S. Varga and T. Anderson to C. J.
Heltemes, respectively, the Westinghouse Electric Corporation submitted Amendments 24 and 25 to the RESAR-41 application, which addressed each of these matters.
The NRC staff has reviewed Amendments 24 and 25 for completeness and has concluded that the Westinghouse Electric Corporation has addressed each of these matters.
The NRC staff considers this to be an acceptable basis for extending PDA-3 for two additional years.
If the NRC staff is informed by a utility-applicant that it intends to reference the RESAR-41 Nuclear Steam Supply System design after December 31, 1978, it will then perform a detailed review of Amendments 24 and 25 to assure that each of the identified matters has been acceptably resolved for the RESAR-41 Nuclear Steam Supply System 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 matte-c to be deferred on these designs until e utility-applicant requirement for that review is identified.
., Amendment No.1 to PDA-3 is effective as of its date of issuance and shall expire on December 31, 1980, unless earlier superseded by issuance of a final design approval for the RESAR-41 Nuclear Steam Supply System design, or unless extended by the NRC staff.
The expiration of PDA-3, as amended, should not affect use of the RESAR-41 Nuclear Steam Supply System design for reference in any construction permit application docketed prior to such date.
A copy of Amendment No. I to PDA-3 dated December 28, 1978 is available for public inspection at the Nuclear Regulatory Commission's Public Document Room at 1717 H Street, N. W., Washington, D. C. 20555.
Dated at Bethesda, Maryland this 28th day of December 1978.
