NOTE: NIF, National Ignition Facility; FTF, Fusion Test Facility; DEMO, Demonstration Power Plant; HAPL, High Average Power Laser program; GA, General Atomics; ATFF, Automated Target Fabrication Facility; MFE, magnetic fusion energy; IFMIF, International Fusion Materials Irradiation Facility; ITER, International Thermonuclear Experimental Reactor; JET, Joint European Tokamak; TFTR, Tokamak Fusion Test Reactor; and TSTA, Tritium System Test Assembly.

a The various drivers are at different TRLs in FY2012. For example: NIF single-shot laser, TRL 9; Repetition rate of IFE solid state lasers, TRL 4; Heavy-ion beams: TRL 3 to TRL 6, if existing but different accelerators are taken into account; Pulsed power, TRL 5.

b Present targets are fixed. Repetitive targeting of DT targets on the fly will have to wait for FTF.

c The answer depends on which type of first wall is considered—thick liquid wall, thin liquid wall, or solid wall.

 

Conclusion 4-8: There are several technology development areas in which there is overlap and/or synergy between magnetic fusion energy (MFE) and inertial fusion energy (IFE).

Recommendation 4-8: The overlap and synergies that exist between MFE and IFE technology development areas should be exploited. The Department of Energy should assure that the research program plans for IFE and MFE are coordinated and that the research results are fully shared between the two programs.
