July 19, 1989 Docket Nos:
50-269 50-270 50-287 Mr. H. B. Tucker, Vice President Nuclear Production Department Duke Power Company 422 South Church Street Charlotte, North Carolina 28242
Dear Mr. Tucker:
SUBJECT:
SAFETY EVALUATION REPORT ON DPC-NE-2003, "CORE THERMAL-HYDRAULIC METHODOLOGY USING VIPRE-01" (TACS 69377/69378/69379)
The staff and its consultant, International Technical Services, have reviewed your Topical Report DPC-NE-2003, "Core Thermal-Hydraulic Methodology Using VIPRE-01" submitted for application to the Oconee Nuclear Station, Units 1, 2 and 3. We have found the topical report to be acceptable for referencing in the core thermal-hydraulic analyses for the Oconee units with the following limitations:
(1)
The acceptable DNBR limit is 1.18.
Acceptance of a DNBR limit less than 1.18 will require analysis of a broader CHF data base and detailed staff review.
(2)
The studies provided in the topical report were performed with the fuel assembly desigh currently used in the Oconee units.
Although the approach is acceptable for future fuel assembly designs, you should ensure that the selected correlations are used within their applicability ranges.
A copy of our Safety Evaluation Report is enclosed. This completes our action under TAC Nos. 69377, 69378 and 69379.
Sincerely, Original signed by:
Leonard A. Wiens, Project Manager Project Directorate 11-3 Division of Reactor Projects -
