The DOE Generation III+ SMR programme Tier 2 round is expected to fund additional SMR deployments beyond the Tier 1 TVA and Holtec awards. The $94 million round announced May 14, 2026 was described as Tier 2 work addressing gaps in licensing, supply chain, and site preparation. A further Tier 2 round may be issued if additional funds become available. Potential awardees include utilities and project developers that applied in the April 2025 application window but were not selected in the first round.
