UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 lo October 1, 1998 Mr. W. R. McCollum Vice President, Oconee Site Duke Energy Corporation P. 0. Box 1439 Seneca, SC 29679
SUBJECT:
REVIEW OF UPDATED FINAL SAFETY ANALYSIS REPORT, CHAPTER 15, TRANSIENT ANALYSIS METHODOLOGY SUBMITTAL - OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 (TAC NOS. M99349, M99350, AND M99351)
Dear Mr. McCollum:
By letter dated July 30, 1997, Duke Energy Corporation (DEC) submitted Topical Report DPC-NE-3005-P, "UFSAR [Updated Final Safety Analysis Report] Chapter 15 Transient Analysis Methodology," for NRC staff review and approval. Additional information was supplied by DEC by letter dated July 23, 1993. The topical report describes the methodology DEC used to analyze the nonloss-of-coolant accident (non-LOCA) UFSAR Chapter 15 transients and accidents for the Oconee Nuclear Station (Oconee), Units 1, 2, and 3. The objective of this topical report is to implement a revised non-LOCA transient and accident analysis methodology and establish a new licensing basis for Oconee. As you explained in the submittal, most of the computer codes and simulation models referenced in the report have been previously reviewed by the staff and approved for application to the Oconee reload design and in response to Generic Letter 83-11. This topical report is a specific application of these models to the analysis of the Oconee UFSAR Chapter 15 transients and accidents.
The staff has reviewed the topical report and finds it acceptable with some exceptions, as explained in the enclosed safety evaluation. These exceptions have been discussed with your staff and will be addressed in a revision to the topical report that will be submitted for staff review and approval. As a result, staff activity concerning this topical report is not completed and will be reinitiated using new TAC numbers when the revision is received.
However, some of the methodology described in this topical report is also important in certain design basis considerations for conversion of the current Oconee Technical Specifications (TS) to the improved TS. The submittal for this conversion is under staff review (TAC Nos. M99912, 9810050251 981001O.
