Title 42 › Chapter 161— DEPARTMENT OF ENERGY RESEARCH AND INNOVATION › Subchapter III— DEPARTMENT OF ENERGY OFFICE OF SCIENCE POLICY › § 18645
Creates a program run by the Director of the Office of Science to fund and lead fusion energy research so the United States can build cost-competitive fusion power plants and a strong fusion industry. The program must fund basic plasma science at very high temperatures and densities, develop materials that can survive fusion neutron, plasma, and heat conditions, and study tokamak and inertial fusion approaches (ion beam, laser, and pulsed power). The Director must assess whether new test facilities are needed and whether one new facility could serve both magnetic fusion and next-generation fission needs. The law requires reports and deadlines: a 10-year research plan to Congress not later than 2 years after September 28, 2018 (with three budget scenarios, one using 3-percent annual growth), a milestone-based development program set up within 6 months after enactment to fund projects that meet technical milestones and aim for full-scale improvements within 10 years, and at least two national teams created not later than 180 days after August 9, 2022 to design pilot plants. It directs coordination with ARPA–E and other offices, support for alternative fusion concepts and advanced computing, creation of a national High-Performance Computing for Fusion Innovation Center, and construction of a Material Plasma Exposure Experiment facility with a 1 Tesla target field, 10 MW/m2 target flux, and the ability to expose irradiated samples, with full operations before December 31, 2027 if funds allow. It also requires upgrading the Matter in Extreme Conditions endstation with full operations before December 31, 2028. The law also authorizes specific funding amounts. Materials R&D: $50,000,000 per year for fiscal years 2023–2027. Inertial fusion: $25,000,000 per year for fiscal years 2021–2027. Alternative/enabling concepts: $50,000,000 per year for fiscal years 2021–2027. Milestone-based program: $45,000,000 (FY2021), $65,000,000 (FY2022), $105,000,000 (FY2023), $65,000,000 (FY2024), $45,000,000 (FY2025), $45,000,000 (FY2026), $45,000,000 (FY2027). National teams: $35,000,000 (FY2023), $50,000,000 (FY2024), $65,000,000 (FY2025), $80,000,000 (FY2026), $80,000,000 (FY2027). Material Plasma Exposure Experiment construction: $21,895,000 (FY2023) and $3,800,000 (FY2024). Overall Office of Science fusion authorizations: $996,000,000 (FY2021); $921,000,000 (FY2022); $1,025,500,400 (FY2023); $1,043,489,724 (FY2024); $1,053,266,107 (FY2025); $1,047,962,074 (FY2026); $1,114,187,798 (FY2027).
