Title 42 › Chapter CHAPTER 161— - DEPARTMENT OF ENERGY RESEARCH AND INNOVATION › Subchapter SUBCHAPTER III— - DEPARTMENT OF ENERGY OFFICE OF SCIENCE POLICY › § 18641
The Director must run a basic energy sciences program to study materials, chemistry, physical biosciences, geosciences, and related fields. The goal is to understand and control matter and energy at very small scales so new energy technologies can be made and to help the Department with energy, environment, and national security work. Chemistry work must focus on sustainable chemistry that gives cleaner, safer, and cheaper alternatives. The Director must also give competitive, peer-reviewed awards to multi‑institution teams for fundamental and use‑inspired energy research. Those awards run for 4 years, may be renewed by reapplying, can be ended early for poor performance, and may not be used to build new buildings. The Secretary must develop, build, run, and keep up national user facilities like x‑ray light sources, neutron sources, nanoscale centers, and AI‑driven autonomous chemistry and materials facilities. The law requires specific upgrades, deadlines, and funding: the Advanced Photon Source upgrade must reach full operation before March 31, 2026 and has $14,200,000 authorized for FY2023; the Spallation Neutron Source proton power upgrade must reach full operation before July 30, 2028 (optionally in 2025) with $17,000,000 for FY2023, $14,202,000 for FY2024, and $1,567,000 for FY2025; a second target station at the Spallation Neutron Source must reach full operation before December 31, 2033 (optionally in 2029) with $127,000,000 for FY2023, $205,000,000 for FY2024, $279,000,000 for FY2025, $300,000,000 for FY2026, and $281,000,000 for FY2027; the Advanced Light Source upgrade must reach full operation before September 30, 2029 with $135,000,000 for FY2023, $102,500,000 for FY2024, $50,000,000 for FY2025, and $1,400,000 for FY2026; the Linac Coherent Light Source II upgrade must reach full operation before December 31, 2026 with $100,000,000 for FY2023, $130,000,000 for FY2024, $135,000,000 for FY2025, and $99,343,000 for FY2026; a cryomodule repair and maintenance facility for LCLS‑II has $29,300,000 for FY2023, $24,000,000 for FY2024, $20,000,000 for FY2025, and $15,700,000 for FY2026; Nanoscale Science Research Centers recapitalization has $25,000,000 for FY2023 and $25,000,000 for FY2024; additional experimental stations for the National Synchrotron Light Source II must begin by September 30, 2036 (may begin in 2033). The Director must also do accelerator R&D, support advanced computing research in chemistry and materials, set up up to 6 computational materials and chemical sciences centers (competitive awards up to 5 years, renewable), and build a web platform and database for computed materials data with $10,000,000 authorized each year for FY2023 through FY2027. Annual authorized amounts for the Office of Science activities under this part are $2,685,414,000 for FY2023; $2,866,890,840 for FY2024; $2,987,727,170 for FY2025; $3,062,732,781 for FY2026; and $3,080,067,167 for FY2027.
