The US Department of Energy has moved to accelerate nuclear power deployment with a series of large financing commitments. In June 2026, the department's Office of Energy Dominance Financing conditionally committed $17.5 billion in loan facilities to support construction of up to 10 Westinghouse AP1000 reactors in the United States, financing the long-lead equipment needed to build them.
The commitment adds to a string of federal actions. In December 2025, the department awarded $800 million to the Tennessee Valley Authority and Holtec to advance small modular reactor deployment. In November 2025, it closed a $1 billion loan to Constellation to help finance the Crane Clean Energy Center restart in Pennsylvania.
Congressional funding has reinforced the push. A fiscal 2026 Energy and Water Development appropriations bill directed more than $49 billion to the department, including $1.785 billion for its Office of Nuclear Energy. An additional $3.1 billion was reprogrammed to nuclear energy work, supporting cost-shared reactor demonstrations by TerraPower and X-energy and risk-reduction awards for other reactor concepts.
Together the commitments represent one of the largest federal financing efforts for nuclear power in years, aimed at rebuilding domestic reactor construction capability and supply chains as electricity demand rises across the country.
