The FY 2019 funding bill provides $564 million for FES, compared to $532 million in FY 2018. This breaks down to $432 million for the domestic FES program, compared to $410 million in FY 2018, and $132 million for US contributions to the ITER project, compared to $122 million in FY 2018.

A House-Senate conference report accompanying the bill also states: "The Fusion Energy Sciences Advisory Committee is directed to work with the Office of Nuclear Energy to review establishing a reactor concepts research, development, and deployment activity" and "to provide to the Committees on Appropriations of both Houses of Congress not later than 180 days after the enactment of this Act a briefing on a recommendation, which if supported, will include a technical plan, program and eligibility requirements, and funding profile for future fiscal years."

The funding bill also provides to the Inertial Confinement Fusion and High Yield program $545 million, the same as in FY 2018. The report specifies that within this amount "$344 million shall be for the National Ignition Facility, $80 million shall be for OMEGA, $63.1 million shall be for the Z facility and $7 million shall be for the Naval Research Laboratory." It also states: "Not later than 60 days after the enactment of this Act, the NNSA shall provide to the Committees on Appropriations of both Houses of Congress a report on the impacts to the ICF program of shifting to a full-cost recovery model for the National Ignition Facility."
