Fusion-fission hybrid papers and proceedings
In the early 1950s, both fission and fusion processes were under serious study, and ways to combine them, that is hybridize them, began.
By 1974 the studies had matured to the point that a review meeting was held. This collection of reports will help readers brief themselves on
The following three proceedings summarize the early work up to 1977.

POWER VERSUS FUEL PRODUCTION.
The question of hybrids designed to produce fuel for fission reactors or electrical power only
or some combination of both was studied in a 544 page report. Because fusion reactors tend to be more expensive to build than fission reactors,
the power only option was not found economically favorable unless the plant size was very large to obtain strong economy of scale.

Laser fusion as a fuel producer. A laser fusion neutron source with a lead neutron multiplier was studied for fuel production and power.

LLNL COORDINATED STUDIES 1978-1984.
A coordinated set of studies followed involving Lawrence Livermore National Laboratory,
PPPL, ORNL, INL, ANL, GA GE, W and Bechtel among others. The following reports document some of this work.
A yin-yang coil magnetic mirror with a fast fission fuel producing blanket provided enough energy multiplication and fuel sales to make the
low gain (Q=1) system close to economical. D. J. Bender, K. R. Schultz, et al., “Reference design for the standard mirror hybrid reactor,”
UCRL-52478, GA-A14796 (1978). 542 pages.
The new magnetic mirror configuration, Tandem mirror, formed the basis for this design that had large enough Q values so that high energy
multiplication by fission was not necessary and the ideas of fuel production while suppressing fissioning by use of beryllium neutron
multiplications was employed. The team involved GA, GE, Bechtel and LLNL. R. W. Moir, et al., “Tandem Mirror Hybrid Reactor Design Study
Final Report”, Lawrence Livermore National Laboratory, Livermore, CA, UCID-18808 (1980). 636 pages
The ideas evolved further resulting in this well documented report: J. D. Lee, et al., “Feasibility Study of a Fission-Suppressed Tandem-Mirror
Hybrid Reactor”, Lawrence Livermore National Laboratory, Livermore, CA, UCID-19327 (1982). Part 1. Part 2.
The ideas further evolved with examples using liquid lithium as a neutron multiplier. D. H. Berwald, et al., “Fission-Suppressed Hybrid
Reactor-The Fusion Breeder”, Lawrence Livermore National Laboratory, Livermore, CA, UCID-19638 (1982).

Two studies, one for the tandem mirror and a very similar design for the tokamak, were carried out in the last days of the fusion-fission studies
before they were stopped.

TRITIUM PRODUCING FUSION REACTOR STUDIES.
The DOE studied many options for a replacement production reactor with the idea of replacing the Savannah River reactor. The team carried
out design studies of relatively low technology tandem mirror and a tokamak fusion machines to produce tritium.

IN 1987 AN ACADEMY STUDY CHAIRED BY JOHN SIMPSON REVIEWED THE HYBRID WORK.
“Outlook for the Fusion Hybrid and Tritium-Breeding Fusion Reactor.” The fusion-fission hybrid studies ended with this work and like
Rip van Winkle, the field slept for twenty years.
Researchers began to increase interest in hybrids. For example, fuel production: P-H. Rebut, From JET to the reactor,“Plasma Phys. Control.”
