Thermomechanical dynamic behavior of the solid wall of a pellet fusion reactor

Solid- and liquid-wall reactors are now under consideration as pellet fusion reactor systems. A thermal shock problem induced by a deposition of soft x-rays may be more serious to the solid-wall reactor system than to the liquid-wall reactor system. The engineering feasibility of the solid-wall reactor system is assessed by means of analytical solutions of the thermomechanical dynamics associated with a sudden and uniform temperature rise, and of finite element solutions of the reactor dynamics associated with the surface heating due to the deposition of soft x-rays. 16 refs
