Notes
Aug 7, 2025 letter also cut the hour estimate to ~12,200 h (from 8,000 safety + 6,000 environmental). The letter does not cite EO 14300. Issued ~1 month after the accelerated target; fetched sources give no reason. No FR notice establishing a Licensing Board was found for this application in an FR API search. NRC decision target: originally 2025-12, latest 2025-11-13. Schedule: Original schedule (NRC letter Aug 2, 2024, ML24184A171) targeted 12/2025; Aug 7, 2025 letter accelerated it to 11/13/2025, citing 'several staff efficiencies'; actual 12/16/2025.
