Fuel production characteristics of fusion hybrid reactors

The potential role of hybrid systems in the production of fuel for fission reactors is examined in the context of a possible serious fuel shortfall developing early in the next century. Various proliferation-resistant fuel-cycle options are considered, including the use of the Th/233U fuel cycle and the Refresh Concept. It is concluded that the fusion hybrid reactor has a high potential to extend fuel resources for nuclear power stations. The hybrid concept also appears to offer the flexibility to operate with a variety of fuel-cycle options. Furthermore, a demonstration of fissile-fuel production in a hybrid based on the tokamak concept appears to be a feasible near-term goal. (author)
