High temperature plasma facing components designs for biomass hybrid reactor: GNOME

Neutronics analysis for a tokamak reactor GNOME was studied by a three dimensional Monte Calro simulation code; MCNP-5. Distribution of nuclear heat was obtained from the calculated and applied into in-board cooling duct designs for the GNOME reactor. The pressure drop at the duct and corresponding pumping power were evaluated to survey the operational windows of the tokamak with SiC insulated He/PbLi dual coolants blankets. Besides, the pressure drop at the SiC structure PbLi cooled divertor was also evaluated in order to confirm the feasibility of the PbLi cooled divertor.
