Abstract
The first wall of a nuclear fusion reactor is a plasma facing material and it has to withstand the thermal shocks due to irradiation from the nuclear fusion reaction. The energy after each explosion of the small DT fuel-pellets in Inertial Confinement Fusion Reactors is released in a pulse mode. In dry wall concepts of chamber, without or lowdensity gas protection, the first wall is composed by a thin armor of refractory material that protects the structural material from high temperatures and other atomistic effects. X-rays and ions carry one third of the explosion energy. That energy is deposited in the first microns of the armor during pulses of microseconds. The armor reaches high temperatures located near the surface, while the thermodynamic heat is released through the structural material in contact with the coolant.
