II. ABSTRACT
Fusion-fission hybrid systems, fast breeder systems, and
accelerator breeder systems were compared on a common
basis using a simple economic model. Electricity prices
based on system capital costs only were computed, and
were plotted as functions of five key breeder system
parameters. Nominally, hybrid system electricity costs
were about twenty-five per cent lower than fast breeder
system electricity costs, and fast breeder system elec-
tricity costs were about forty per cent lower than accel-
erator breeder system electricity costs. In addition,
hybrid system electricity costs were very insensitive to
key parameter variations on the average, fast breeder system
electricity costs were moderately sensitive to key parameter
variations on the average, and accelerator breeder system
electricity costs were the most sensitive to key parameter
variations on the average.
The status of the three advanced breeders was outlined. Fast
breeders are developed the furthest, and require demonstra-
tion of the engineering feasibility of short doubling time
safe systems and of the economic feasibility of commercial
prototypes. The accelerator breeder is next furthest along.
Accelerators must be developed with orders of magnitude
increase in pulse length (steady state operation), an order
of magnitude increase in conversion efficiency, and three
orders of magnitude increase in beam current. Major problems
