IMPLEMENTATION CONSIDERATIONS OF COUPLING DEDICATED FISSILE AND FUSILE PRODUCTION FUSION AND FISSION REACTORS.

The steady-state operational mode of coupled systems of dedicated fusion reactors producing fissile fuel for fission reactors which, in turn, produce the fusile fuel for the fusion reactors, is discussed. It is found that if the breeding capacity of either system is increased, the breeding capacity in the other system can be relaxed, and that the ratio of total fission to fusion power depends on these breeding capacity choices. The coupling is shown to be potentially more economical than a pure-fusion system. The different alternatives for producing the tritium feed for fusion reactors are compared.
