Effects of kinetic profiles on neutron wall loading distribution in CFETR

The China Fusion Engineering Test Reactor（CFETR） is under design, which aims to bridge the gaps between ITER and the future fusion power plant. The neutron wall loading（NWL） depends on the neutron source distribution, which depends on the density and temperature profiles. In this paper, we calculate...

Summary:The China Fusion Engineering Test Reactor（CFETR） is under design, which aims to bridge the gaps between ITER and the future fusion power plant. The neutron wall loading（NWL） depends on the neutron source distribution, which depends on the density and temperature profiles. In this paper, we calculate the NWL of CFETR and study the effects of density and temperature profiles on the NWL distribution along the first wall. Our calculations show that for a 200 MW fusion power, the maximum NWL is at the outer midplane and the vaule is about 0.4 MW m^-2. The density and temperature profiles have little effect on the NWL distribution. The value of NWL is determined by the total fusion power.
