Option 7: In this option, LEU (235U/238U) converters, denatured 235U and 233U
converters, and denatured 233U breeders are operated outside the energy centers and
Pu/Th converters and Pu-U/Th breeders (Pu-U cores, Th blankets) are permitted inside
the centers. Spent fuel is returned to the secure energy centers for reprocessing.
The fissile uranium is recycled into the outside reactors and the inside breeders,
and the plutonium is recycled in the inside converters and breeders. With the reactors
used, only a light rrPu-to-233Urr transmutation rate is realized. This case represents
the first time a denatured breeder is introduced in the system.

The fissile uranium is recycled into the outside reactors and the plutonium into the
