Subject:

ESBWR Design Certification Annual 10 CFR 50.46 Report for 2018

Reference:

1. Letter, J. G. Head (GEH) to Document Control Desk (NRC), M170244, ESBWR Design Certification Annual 10 CFR 50.46 Report for 2017, October 30, 2017.

GE Hitachi Nuclear Energy (GEH), as the applicant for the ESBWR Design Certification (10 CFR Part 52, Appendix E), submits this annual report under 10 CFR 50.46, "Acceptance Criteria for Emergency Core Cooling Systems for Light-Water Reactors." Specifically, is the 2018 annual report for the ESBWR Design Certification for emergency core cooling system (ECCS) evaluation model changes or errors that affect the peak cladding temperature (PCT) calculation. Since the 2017 report (Reference 1), no evaluation model changes have occurred.

By this letter, GEH also notifies the licensees, DTE Electric Company for Enrico Fermi Nuclear Plant Unit 3, and Dominion Virginia Power for North Anna Unit 3, in accordance with 10 CFR 50.46(a)(3)(iii), because the licenses for these units reference the ESBWR Design Certification.

Please contact me if you have any questions regarding this information.

Sincerely, Michelle P. Catts Senior Vice President, Regulatory Affairs
