SMR licensing advances, but commercial replication and local acceptance remain unproven

TVA's Clinch River permit, TerraPower's Natrium permit, NuScale's Romanian approval and MARVEL's completed safety checks provide regulatory or demonstration signals without establishing financed, operating fleets. Unity's 2027 DOE DOME test is similarly a demonstration milestone; Clinch River and the proposed NuScale/ENTRA1 build still lack key design, funding and construction commitments.
