Preliminary design and neutronic analysis of a laser fusion driven actinide waste burning hybrid reactor

The LDAB system investigated uses partitioned power reactor generated actinide wastes dissolved in a molten tin alloy as fuel. A novel fuel processing concept based upon the high temperature precipitation of ''actinide-nitrides'' from a liquid tin solution is proposed. This concept will allow for fission product removal to be continuously performed entirely within the device. Thus, the actinide transmutation process will be less hazardous than in systems with a fixed irradiation cycle because the need to reprocess, refabricate, and transport actinide wastes once charged to the system is eliminated. The LDAB is similar to other hybrid actinide burner designs in producing fission power copiously. The first wall and cavity are adapted from a University of Wisconsin pure laser fusion reactor design
