TVA submitted the application in 2025; the site already held an NRC early site permit (2019). TVA has not announced a construction start or an in-service date and says it is still negotiating cost sharing with industry partners, so no EPC is recorded and the COD fields stay empty. Capacity is the 300 MWe stated by the NRC and GE Vernova Hitachi.","tags":["us","smr","bwrx-300","tva"],"updated_at":"2026-10-12","slippage_years":null}}
