The US small modular reactor industry crossed a psychological threshold this year. No SMR has entered commercial operation domestically, but 2026 is shaping up as the year the first construction permits and criticality milestones actually land — and the trigger isn’t climate policy, it’s AI data-center power demand.

The Federal Push

The Department of Energy’s Gen III+ SMR Pathway to Deployment Program has become the primary vehicle for de-risking early builds. DOE issued a $900 million solicitation in March 2025, followed by $800 million in Tier 1 awards in December 2025 to the Tennessee Valley Authority and Holtec Government Services. In May 2026, DOE added a further $94 million across eight companies under Tier 2, targeting licensing, supply chain, and site preparation gaps that have historically stalled domestic nuclear projects.

Ukrainian drone forces struck the Tuapse oil refinery for the fourth time in two weeks on May 1, reigniting fires that Russian emergency services had claimed extinguished less than 24 hours earlier. Russia’s average refinery capacity has dropped to its lowest level since 2009. The Tuapse facility — a Rosneft-operated complex with an annual crude processing capacity of approximately 12 million tonnes and direct connection to a Black Sea marine terminal — has been effectively taken off line by a campaign that did not require a single manned aircraft to penetrate Russian air defenses.
