• AGORA fuel product will provide Dominion Energy greater security of supply and commercial competitiveness 4

Submittal Strategy

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

• Scheduled for Mid-November 2020

2) Submit for approval batch implementation of AGORA VQP

• Scheduled for End Q1 2021

3) Submit for approval SPS Spent Fuel Pool Criticality Analysis

• Scheduled for End Q2 2021

• Updated Dominion methodology, increase enrichment limit, include Gadolinia in Licensing Basis (required for AGORA) 5
