SUBJECT:
REVIEW OF TOPICAL REPORT DPC-NE-3000-PA, REVISION 2, "THERMAL-HYDRAULIC TRANSIENT ANALYSIS METHODOLOGY" OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 (TAC NOS. MA1127, MA1128, AND MA1129)
Dear Mr. McCollum:
By letter dated December 23, 1997, Duke Energy Corporation (DEC/the licensee) submitted Revision 2 to Topical Report DPC-NE-3000-PA, "Thermal-Hydraulic Transient Analysis Methodology," for NRC staff review and approval. The report describes changes to thermal-hydraulic transient analysis methodology that are due to: (1) simulation model revision to reflect the new Mk-B1 1 fuel assembly design; (2) application of the new critical heat flux correlation (BWU-Z with the Mk-B1 1V multiplier); and (3) several RETRAN model improvements.
Based on our review of the submittal, and as explained in the enclosed Safety Evaluation, the staff has determined that the revisions incorporating the Mk-B1 1 fuel assembly design, BWUZ critical heat flux correlation with the Mk-B1 1V multiplier, and RETRAN model are acceptable for applications to non-loss-of-coolant accident transient and safety analysis.
Sincerely, ORIGINAL SIGNED BY:
