Abstract:
Tungsten is a candidate material for divertor and armor of plasma facing components because of its high melting point, low erosion rate, and other attractive properties. However, during the nuclear phase of ITER and other magnetic confinement fusion devices, fast neutron generated from nuclear fusion reaction will degrade the mechanical properties of tungsten. Moreover, the tungsten divertor will also face the challenge of high heat flux during normal operation. Thus, the investigation on high temperature neutron irradiation effect on tungsten is necessary in order to provide data for the engineering design of the components.
