From page 29...
... A blanket designed to optimize fissile fuel production is usually termed a fusion-fission symbiont, while one designed to optimize power production is termed a fusion-fission hybrid. Notice that up to five fissile atoms can be obtained in this cascade process for each fusion-produced neutron, and recalling that with fuel recycling each fissile atom can yield 300 MeV in an external fission burner (thermal reactor)

... The symbiont concept is clearly an alternative to the fission breeder, with possible advantages in terms of controlling accidental increases in reactivity, and with additional possible advantages under circumstances where fissile fuel production for an existing reactor complex is more important than the expansion of generating capacity.* In this context, it is also necessary to consider the "electrical breeding" or spallation concept.

From page 31...
... Advanced fusion fuel cycles, such as p - 11B, in which much of the energy is emitted as hard x-rays, offer unique possibilities for chemical fuel production. Given our present state of understanding, it is difficult to draw any conclusions about the merits of configuring fusion reactors such that the bulk of their net energy output is realized through the production of chemical fuels.

... 32 SUMMARY In conclusion, we do not believe that any of the alternative approaches to pure fusion have been examined in sufficient detail to warrant a marked change in present plans, which have as their primary goal the development of pure-fusion reactors.
