Title 42 › Chapter CHAPTER 161— - DEPARTMENT OF ENERGY RESEARCH AND INNOVATION › Subchapter SUBCHAPTER III— - DEPARTMENT OF ENERGY OFFICE OF SCIENCE POLICY › § 18645
Requires the Director of the Office of Science to run a nationwide fusion energy research and technology program to solve the science and engineering problems needed to build cost-competitive fusion power and to support a U.S. fusion industry. The program must fund basic plasma and high-temperature matter research; find and test materials that can survive fusion conditions; improve tokamak designs; support inertial fusion work (ion beam, laser, pulsed power) with universities and national labs to make targets, models, diagnostics, and drivers; and back alternative and enabling concepts (examples: advanced stellarators, non‑tokamak low-field options, magnetized target fusion, high‑temperature superconductors for high magnetic fields, liquid-metal inner walls, advanced heat/fuel blankets, and advanced computing). The Director must coordinate with ARPA‑E, keep U.S. researchers connected to top facilities including ITER, set up a milestone-based industry funding program within 6 months of enactment to push projects toward commercial-scale progress within 10 years, form at least two national teams within 180 days after August 9, 2022 to design pilot plants, create a high-performance computing program and a national HPC for Fusion Innovation Center, and build a Material Plasma Exposure Experiment facility with a 1 Tesla target field, 10 MW/m2 target energy flux, and ability to test previously irradiated samples, with full operations by December 31, 2027. The Director must also upgrade the Matter in Extreme Conditions endstation with full operations by December 31, 2028, produce a 10-year research plan within 2 years after September 28, 2018 under three budget scenarios (including a 3% growth case), and run reviews and reports including a National Academy review and annual program partnership reports. Authorized funding and deadlines include: $50,000,000 per year for materials activities for each of fiscal years 2023–2027; $25,000,000 per year for inertial fusion for each of fiscal years 2021–2027; $50,000,000 per year for alternative/enabling concepts for each of fiscal years 2021–2027; milestone program funding of $45,000,000 (FY2021), $65,000,000 (FY2022), $105,000,000 (FY2023), $65,000,000 (FY2024), $45,000,000 (FY2025), $45,000,000 (FY2026), and $45,000,000 (FY2027); national team funding of $35,000,000 (FY2023), $50,000,000 (FY2024), $65,000,000 (FY2025), $80,000,000 (FY2026), and $80,000,000 (FY2027); Material Plasma Exposure Experiment construction funding of $21,895,000 (FY2023) and $3,800,000 (FY2024); and Office of Science fusion authorizations of $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), and $1,114,187,798 (FY2027).
