; and (2) the Director shall provide an assessment of— (A) the need for 1 or more facilities that can examine and test potential fusion and next generation fission materials and other enabling technologies relevant to the development of fusion power; and (B) whether a single new facility that substantially addresses magnetic fusion and next generation fission materials research needs is feasible, in conjunction with the expected capabilities of facilities operational as of the date of enactment of this Act. (b) Tokamak research and development The Director shall support research and development activities and facility operations to optimize the tokamak approach to fusion energy. (c) Inertial fusion energy research and development The Director shall support research and development activities for inertial fusion for energy applications. (d) Alternative and enabling concepts The Director shall support research and development activities and facility operations at institutions of higher education, National Laboratories, and private facilities in the United States for a portfolio of alternative and enabling fusion energy concepts that may provide solutions to significant challenges to the establishment of a commercial magnetic fusion power plant, prioritized based on the ability of the United States to play a leadership role in the international fusion research community. (e) Coordination with ARPA–E The Director shall coordinate with the Director of the Advanced Research Projects Agency–Energy (referred to in this subsection as ARPA–E ) to— (1) assess the potential for any fusion energy project supported by ARPA–E to represent a promising approach to a commercially viable fusion power plant; (2) determine whether the results of any fusion energy project supported by ARPA–E merit the support of follow-on research activities carried out by the Office of Science
