Radiation Hydrodynamic Simulations Of An Inertial Fusion Energy Reactor Chamber

Inertial fusion energy reactors present great promise for the future as they are capable of providing baseline power with no carbon footprint. Simulation work regarding the chamber response and first wall insult is carried out using the 1-D BUCKY radiation hydrodynamics code for a variety of differing chamber fills, radii, chamber obstructions and first wall materials. Discussion of the first wall temperature rise, x-ray spectrum incident on the wall, shock timing and maximum overpressure are presented. An additional discussion of the impact of different gas opacities and their effect on overall chamber dynamics, including the formation of two shock fronts, is also presented. This work is performed under collaboration with Lawrence Livermore National Laboratory at the University of Wisconsin-Madison's Fusion Technology Institute.
