“…Leonard, J r . , and W.C. Wolkenhauer of Pacific Northwest Laboratories have reported extensive numerical computations of the neutronic performance of hybrid reactors based on subcritical fission lattices [26,27] . Their most recent results and an excellent summary are given in Leonard's review article [21] but the earlier reports give more detail.…”

The achievement of controlled fusion will make available excess neutrons which can be used in various ways in combined fission-fusion power cycles. The various schemes are here classified as hybrid–in which heavy-element fission occurs in the fusion blanket; symbiotic–in which fissile material is bred in the absence of fission events; and augean–in which the neutron surplus is used to transmute fission reactor waste products. The earliest work in this field, unpublished and originally classified secret, is reviewed. Recent studies of hybrid systems based on subcritical thermal and sub-critical fast-fission blankets are described in detail. An analysis of symbiosis based on the Th-U fuel cycle is summarized. The conditions required for high-level waste transmutation are presented; Augean systems seem best suited to actinide waste burning. It is concluded that basic physics of various fission-fusion systems has been surveyed but the engineering and economic aspects of combined systems have been largely ignored. It remains to be shown whether fission-fusion systems will prove superior to alternative methods of accomplishing the same ends.

“…If one assumes that the relatively cheap uranium currently available will be exploited for power, if one recognizes the unique problems associated with tritium containment, and if one recognizes that the higher actinides represent a major waste disposal problem associated with fission reactors, then it appears that the hybrid reactor might have attractive environmental features. [2] In summary then, a hybrid reactor is a sub-Lawson plasma coupled to a subcritical fissile/fertile assembly which can produce a positive energy balance. Some of the potential advantages of the device are:…”
