“…The concept of accelerator-driven electronuclear facilities was suggested some four decades ago [5] and developed persistently ever since is considered to be a promising technology for waste transmutation. Such facilities differ from conventional nuclear power facilities that are operated in critical mode supported by delayed neutrons.…”

The results of experimental and computer simulation studies of the yields of residual product nuclei in 209 Bi thin targets irradiated by 130 MeV and 1.5 GeV protons are presented. The yields were measured by direct high-precision γ-spectrometry. The γ-spectrometer resolution was 1.8 keV in the 1332 keV line. The γ-spectra were processed by the ASPRO code. The γ-lines were identified, and the cross sections defined, by the SIGMA code using the GDISP radioactive database. The process was monitored by the 27 Al(p,x) 24 Na reaction. Results are presented for comparisons between the 209 Bi(p,x) reaction yields obtained experimentally and simulated by the HETC, GNASH, LAHET, INUCL, CEM95, CASCADE, and ALICE codes.

“…The neutrons produced in this fashion have a broad energy spectrum and are accompanied by an intense gamma-ray flux. Such "electronuclear" sources (based on designs calling for beams of 500-1000 MeV energy at currents of hundreds of milliamperes) have been proposed for materials testing, transuranic isotope production, and fertile-to-fissile conversions [34], It appears that the use of spallation-produced neutrons for fertile-to-fissile conversion is not economic at this time [35] but if fusion reactors prove unattainable and fission breeders are incapable of achieving short enough doubling times, then the electronuclear generation of neutrons will become essential.…”

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 The earliest work in this field, unpublished and originally classified secret, is reviewed.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.

“…Some reactor designs incorporate a thin electrically insulating coatin~on the reactor first wall. Sputtering yields for such insulating coatings would have to he even lower than for Nb because less thickness reduction would be tolerable for a thin coating.With or without a coatinq, redeposition of sputtered wall material may erosion to an acceptable aMount even with the particle fluxes and yields suggested for the 0 pinch pulsed reactor.In the proposed steady state machines (mirror and toroidal), the maximum suoqested flux at the first Hall is aporoximate1y 3 x 10 14 parti-c1es/cm 2 /sec and the averaqe particle energy is expected to be greater than 10 keV (3,4). Again~sing the criterion of Equation 5, the maximum tolerable yield would be 6 x 1~-2 atoms/particle.…”
