UNITED STATES NUCLEAR REGULATORY COMMISSION DOCKET NO. STN 50-470 COMBUSTION ENGINEERING, INCORPORATED STANDARD SAFETY ANALYSIS REPORT (CESSAR SYSTEM 80 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.1 to Preliminary Design Approval No. PDA-2 dated December 28, 1978, for the reference system design of a nuclear steam supply system (NSSS) of a pressurized water reactor as described in the Combustion Engineering, Incorporated (C-E) CESSAR System 80 Preliminary Safety Analysis Report and amendments thereto. PDA-2 was issued by the NRC staff on December 31, 1975 for a three-year period.
Amendment No. I to PDA-2 extends its expiration date from December ll, 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, PDA's for NSSS reference system designs were set to terminate three years after issuance.

2-The Nuclear Regulatory Comission'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 C-E, R. Boyd to P. L. McGill, dated October 19, 1978. By letters dated October 20, 1978, December 7, 1978 and December 20, 1978, A. E. Scherer to C. J. Heltemes, Jr., C-E submitted Appendix A to its CESSAR system 80 Final Safety Analysis Report and Amendments 1 and 2 thereto which addressed each of these matters. The NRC staff has reviewed Appendix A and the amendments thereto for completeness and has conciuded that C-E has addressed each of these matters. The NRC staff considers this to be an acceptable basis for extending PDA-2 for two additional years.
If the NRC staff is informed by a utility-applicant that it intends to reference the CESSAR system 80 preliminary design after December 31, 1978, it will then perform a detailed review of Appendix A and amendments thereto to assure that each of the identified matters has been acceptably resolved for the CESSAR System 80 preliminary 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 pennits the detailed review of the identified matters to be deferred on these designs until a utility-applicant requirement for that review is identified.
,. Amendment No. I to PDA-2 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 CESSAR System 80 design, or unless extended by the NRC staff. The expiration of PDA-2, as amended, should not affect use of the CESSAR System 80 design for reference in any construction pennit application docketed prior to such date.
A copy of Amendment No. I to PDA-2 dated December 28,1978 is available for public inspection at the Nuclear Regulatory Connission's Public Document Room at 1717 H Street, N.W., Washington, D. C.
20555.
Dated at Bethesda, Maryland this 28th day of December 1978.
