Some design aspects of D3He fuel inertial confinement fusion reactor

For a D3He fuel inertial confinement fusion (ICF) reactor, the efficiency of a direct energy recovery system using a capacitor load circuit is estimated to be as high as 70% by simulating the plasma behavior in a magnetic cavity. A three-dimensional (3-D) hybrid code is developed to analyze the instability on the surface of the expanding plasma in the magnetic field. We also performed burn simulations for a pure D3He target that adopts the volume ignition model as the final state of the implosion and found that it seems difficult to obtain the fuel gain required for the ICF reactor.
