Neutronics and photonics calculations for the tokamak experimental power reactor

The results of one-dimensional neutronic and photonic calculations that compare the nuclear performance of blanket and shield designs proposed for use in the Tokamak Experimental Power Reactor are presented. The nuclear analysis was carried out for both nonbreeding and tritium-breeding blanket modules to compare the spatial variations of the radiation flux and energy distributions, nuclear heating, radiation damage, and tritium breeding. Nonbreeding blanket modules that contain potassium plus SS-316 or potassium only as the energy-absorbing medium and breeding blankets that use natural lithium as the fertile material were evaluated as a function of the first-wall cooling scheme.
