Neutron Radiation Effects of the Center Conductor Post in a Spherical Tokamak Reactor

The fully exposed center conductor post (CCP) in a spherical tokamak will receive strong neutron irradiation. The analytical results for a CCP in a spherical tokamak reactor are given considering the irradiation effects such as radiation damage, transmutation, nuclear and resistive heat removal, induced radioactivity and blanket tritium breeding ratio, etc. These results are compared with those for the first wall of conventional tokamaks, assuming the same technical requirements.
