Subject:
DTE Electric Company 1 O CFR 50.46 Annual Report of Fenni 3 Emergency Core Cooling System (ECCS) Model Changes By reference 2, GE Hitachi reported 2 errors in the ECCS model for the Certified ESBWR design; however, the correction of these errors had no impact on the calculated Peak Clad Temperature (PCT). The ECCS evaluation model changes are applicable to the Fermi 3 COL.
Therefore, in accordance with 1 O CFR 50.46 (a)(3)(ii), DTE is reporting these changes on the Fermi 3 docket. contains the 2019 1 O CFR 50.46 report GE Hitachi submitted in reference 2.

ESBWR Design Certification Annual 10 CFR 60.46 Report for 2019
Reference:
_ Certificati_on Annual 1 O CFR 50.46 Report for 2019*, October 8, 2019.
- GE Hitachi Nuclear Energy (GEH), as the applicant for the ESBWR* Design Certification (10 CFR Part 52, Appendix E), submits this annual report u'nder 10 CFR 50.46, "Acceptance Criteria for Emergency Core Cooling Systems for Light-Water Reactors."
Speclfically!
Enclo.sure 1 is the 2019 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. This is an upd.ate to the previous report (Reference 1 ), due to th~
omission of two error notifications_ that were submitted during the last reporting perio_d. Th~
notifications. were zero-degree effects on the PCT calculation, *so, ajthough these evaluation model errors are corrected, there will be no change to, any reported analysis results.
- By this. letter, GEH. also nottfies the licensees, DTE Electric Company for Enrico Fermi Nuclear Plant* Unit 3, and Dominion Virginia Power for North Anna Unit 3, in accordance with 1 O CFR 50.46(a)(3)(iii), because the lice'nses for these units reference the _ESBWR Design Certification.
Please contact me if you have any questions regarding this information.
M190171 October 9, 2019 Sincerely, Michelle P. Catts Senior Vice President, Regulatory Affairs Commitments: No additional commitments are made.
