Summary

The United States must carry out research, development, demonstrations, and commercial work to build the science, engineering, and business base needed to keep the country competitive in fusion energy. It must aim to show electric power or hydrogen production from fusion on the U.S. grid as soon as possible. Not later than 180 days after August 8, 2005, the Secretary must send Congress a plan with cost estimates, budgets, and possible international partners. The plan must make better use of current fusion facilities; strengthen fusion science, technology, theory, and computer modeling; pick new magnetic and inertial fusion projects based on scientific value and cost; fund chosen facilities efficiently; improve sharing of results with other science communities; use inertial confinement facilities for fusion energy work when practical; explore other promising fusion approaches; and, as practicable, follow the Fusion Energy Sciences Advisory Committee’s March 2004 workforce recommendations with regular reassessments. The plan must also describe the status and, when possible, costs and schedules for designing and building national or international facilities to test fusion materials and key fusion technologies. The United States is authorized to join the construction and operation of the ITER project under the April 25, 2007 Agreement, and the Director must coordinate U.S. responsibilities under that Agreement. Within 1 year after the date of enactment of this section, the Secretary must report to Congress on the most recent ITER schedule approved by the ITER Council. Funds authorized under section 18645(o) must provide the following amounts for ITER construction: $374,000,000 for fiscal year 2021; $379,700,000 for fiscal year 2023; $419,250,000 for fiscal year 2024; $415,000,000 for fiscal year 2025; $370,500,000 for fiscal year 2026; and $411,078,000 for fiscal year 2027.

(a)It shall be the policy of the United States to conduct research, development, demonstration, and commercial applications to provide for the scientific, engineering, and commercial infrastructure necessary to ensure that the United States is competitive with other countries in providing fusion energy for its own needs and the needs of other countries, including by demonstrating electric power or hydrogen production for the United States energy grid using fusion energy at the earliest date.
(b)(1)Not later than 180 days after August 8, 2005, the Secretary shall submit to Congress a plan (with proposed cost estimates, budgets, and lists of potential international partners) for the implementation of the policy described in subsection (a) in a manner that ensures that—
(A)existing fusion research facilities are more fully used;
(B)fusion science, technology, theory, advanced computation, modeling, and simulation are strengthened;
(C)new magnetic and inertial fusion research and development facilities are selected based on scientific innovation and cost effectiveness, and the potential of the facilities to advance the goal of practical fusion energy at the earliest date practicable;
(D)facilities that are selected are funded at a cost-effective rate;
(E)communication of scientific results and methods between the fusion energy science community and the broader scientific and technology communities is improved;
(F)inertial confinement fusion facilities are used to the extent practicable for the purpose of inertial fusion energy research and development;
(G)attractive alternative inertial and magnetic fusion energy approaches are more fully explored; and
(H)to the extent practicable, the recommendations of the Fusion Energy Sciences Advisory Committee in the report on workforce planning, dated March 2004, are carried out, including periodic reassessment of program needs.
(2)The plan shall also address the status of and, to the extent practicable, costs and schedules for—
(A)the design and implementation of international or national facilities for the testing of fusion materials; and
(B)the design and implementation of international or national facilities for the testing and development of key fusion technologies.
(c)(1)There is authorized United States participation in the construction and operations of the ITER project, as agreed to under the April 25, 2007 “Agreement on the Establishment of the ITER International Fusion Energy Organization for the Joint Implementation of the ITER Project”. The Director shall coordinate and carry out the responsibilities of the United States with respect to this Agreement.
(2)Not later than 1 year after the date of enactment of this section, the Secretary shall submit to Congress a report providing an assessment of the most recent schedule for ITER that has been approved by the ITER Council.
(3)Out of funds authorized to be appropriated under section 18645(o) of this title, there shall be made available to the Secretary to carry out the construction of ITER—
(A)$374,000,000 for fiscal year 2021;
(B)$379,700,000 for fiscal year 2023;
(C)$419,250,000 for fiscal year 2024;
(D)$415,000,000 for fiscal year 2025;
(E)$370,500,000 for fiscal year 2026; and
(F)$411,078,000 for fiscal year 2027.
