Authorizes the Secretary, subject to certain guidelines, to negotiate an agreement for U.S. participation in ITER (international burning plasma fusion research project).
Directs the Secretary to develop a plan for the participation of U.S. scientists in ITER that includes the U.S. research agenda for ITER, methods to evaluate whether ITER is promoting progress toward making fusion a reliable and affordable source of power, and a description of how work at ITER will relate to other elements of the domestic fusion program.
Directs the Secretary to send to Congress a plan for implementing a domestic burning plasma experiment such as Fusion Ignition Research Experiment (FIRE), if at any time during the negotiations on ITER the Secretary determines that construction and operation of ITER is unlikely or infeasible.
