RESOLUTION OF COMMENTS ON DRAFT SAFETY EVALUATION FOR TOPICAL REPORT WCAP-18240-P/WCAP-18240-NP, REVISION 0, WESTINGHOUSE THERMAL DESIGN PROCEDURE (WTDP)
WESTINGHOUSE ELECTRIC COMPANY By letter dated November 15, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19319B971), Westinghouse Electric Company (Westinghouse) provided comments on the draft safety evaluation (SE) for Topical Report (TR)
WCAP-18240-P/WCAP-18240-NP, Revision 0, Westinghouse Thermal Design Procedure (WTDP). Westinghouse stated that there is proprietary information in the draft SE. The following is the U.S. Nuclear Regulatory Commission (NRC) staffs resolution of these comments:
Draft SE Comments for TR WCAP-18240-P/WCAP-18240-NP, Revision 0:
- 1. Last sentence of the fifth paragraph of Section 3.1.2, Generation of the DNBR Sample, reads in the draft SE: The DNBR value sampled from based on the correlation statistics is then increased to account for subchannel code uncertainty.
Westinghouse suggested that the last sentence of the fifth paragraph of Section 3.1.2, Generation of the DNBR Sample, should be re-worded to read: The sampled DNBR value based on the correlation statistics is then increased to account for subchannel code uncertainty.
NRC Resolution for Comment 1 on Draft SE The NRC staff has reviewed the Westinghouse comment and agrees that proposed wording provides additional clarification. The NRC staff has updated the last sentence of the fifth paragraph of Section 3.1.2, Generation of the DNBR Sample.
Last sentence of the fifth paragraph of Section 3.1.2, Generation of the DNBR Sample, reads now: The sampled DNBR value based on the correlation statistics is then increased to account for subchannel code uncertainty.
- 2. Westinghouse provided proprietary markings on the draft SE.
NRC Resolution for Comment 2 on Draft SE:
The NRC staff reviewed the Westinghouse markings and incorporated them into the final SE.
- 3. Westinghouse provided editorial comments.
NRC Resolution for Comment 3 on Draft SE:
The NRC staff reviewed the Westinghouse comments and finds them acceptable because the changes are editorial in nature.
