5 Impetus for Fuel Transition to GAIA Dominion Energy Nuclear Connecticut (DENC) seeks the following benefits with the proposed transition to Framatome (FRM) GAIA Fuel at Millstone Power Station Unit 3 (MPS3)

M5TM cladding has lower hydrogen uptake improving performance under accident conditions GAIA fuel product will provide Dominion Energy nuclear fleet greater security of supply and commercial competitiveness GAIA fuel product may provide greater operational flexibility for DENC

6 Proposed Schedule DENC desires to spread out NRC review, provide focused topic area submittals, and minimize the potential for overlapping linked submittals (DOM-NAF-2, Appendix F and Reload LAR).

7 Submittal Strategy

1) Submit request for approval of incorporation of Gadolinia fuel absorber in the MPS3 Spent Fuel Pool Criticality Safety Analysis (Not Covered Further)

Scheduled for Q4 2022

2) Submit request for approval of new Appendix F to Generic Fleet Report DOM-NAF-2-P-A containing qualification of VIPRE-D/ORFEO code/correlation pair and its associated Deterministic Design Limit (DDL)

Scheduled for Q4 2022

3) Submit LAR for approval GAIA Thermal-Mechanical Design Methods and site-specific application with GAIA Scheduled for Q2 2023

4) Submit LAR for approval GAIA Small Break and Large Break Methods and site-specific application with GAIA Scheduled for Q2 2023

5) Submit LAR for approval GAIA Reload Scheduled for Q4 2023

8 GAIA ORFEO DDL Approval Request is expected to contain the following attachments:
