Docket Nos. 50-269,.50 and 50-287 August 8, 1994 Mr. M. S. Tuckman Senior Vice President Nuclear Generation Duke Power Company P. 0. Box 1006 Charlotte, North Carolina 28201-1006
Dear Mr. Tuckman:
SUBJECT:
SAFETY EVALUATION REGARDING THE THERMAL HYDRAULIC TRANSIENT ANALYSIS METHODOLOGY DPC-NE-3000 FOR OCONEE NUCLEAR STATION UNITS 1, 2, AND 3 (TAC NOS. M87112, M87113, AND M87114)
By letter dated July 1987, Duke Power Company (DPC), submitted DPC-NE-3000, a topical report documenting DPC's use of the RETRAN computer code for McGuire/Catawba and Oconee. It was determined that DPC's use of the code was acceptable with respect to McGuire/Catawba; however, its use for Oconee licensing type analyses was restricted, primarily due to the difficulty in modeling the performance of the once-through steam generators. DPC submitted supplemental information, dated October 16, 1991, and October 5, 1993, to qualify the RETRAN model for use with Oconee analyses.
The NRC staff and its contractor, International Technical Services, Incorporated (ITS), have completed their review of the topical report and the supplemental submittals. The staff concludes that the DPC modifications of the steam generator model are acceptable. The staff's Safety Evaluation is included as Enclosure 1 and the ITS Technical Evaluation Report is included as. This completes NRC actions for TAC Nos. M87112, M87113, and M87114. If you have questions regarding this matter, contact me at (301) 504-1495.
