Comparison of preliminary D-T and 'catalyzed' D-D system studies

The purpose of the research currently underway is to provide a technological and eventual economic comparison between a reference D-T reactor and a 'catalyzed' D-D reactor. Two separate reactor designs are delineated and examined for this purpose. These systems include plasma parameters, blanket and shield configurations, magnetic-coil configurations, and power conversion systems, including a divertor - direct-convertor system for the D-D design. The initial conclusions reached are as follows: (1) no extraordinary requirements in the D-D reactor in the areas of blanket or magnet technology, (2) advantageous use of minimum-activity blankets and shields, (3) increased overall efficiency via introduction of a divertor - direct-convertor subsystem in the D-D design, and (4) a 65% increase in the toroidal radius of the D-D design compared to the D-T reference value.
