Parametric design space and nuclear analysis of a nuclear-pumped-laser-driven ICF reactor

An initial scoping study of Nuclear-Pumped-Laser-driven ICF power reactors and a neutronics analysis of a selected reactor design have been completed. In the NPL reactor, fusion neutrons induce fission; fission fragments then excite the lasing medium. An advanced DT-seeded, D/sup 3/He-fueled pellet with reduced neutron yield, a subcritical enriched-fuel blanket, and magnetic diversion of charged particles with direct energy conversion at 85-percent efficiency allow reductions in normal ICF design requirements. For example, a 5 MJ NPL driver, 50 pellet gain, 250 MJ fusion yield, and 6 pellets per second result in a nominal 1000 MWe power plant with a net plant efficiency of 53 percent. Energy-cycle balances and neutron transport results are reported.
