Calculations for tritium breeding per source neutron for fusion blanket models

Based on the physics and engineering considerations, two blanket models have been proposed in the literature for a conceptual fusion reactor. The physics calculations for tritium breeding per source neutron has been reported for one of the blankets and are done perhaps with a cylindrical geometry and extended 'plasma' source. However, till now, most of the laboratory experiments undertaken to verify physics calculations are done with a D-T accelerator which can be considered as a point source and a blanket geometry which is spherical in nature. Hence the present calculations, based on Monte-Carlo method which was developed and tested along with nuclear cross-section data, have been undertaken with a specific point source and spherical geometry so that experiments can be directly compared with the calculations.
