6-18 HM HEDL7OOl.70.3 Option 6: In this option, LEU (235U/238U) converters and denatured 235U and 233U converters 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 into the inside converters and breeders. tmsmutation rate is real ized. With the reactors used, only a Zight "PU-~U-~~~U~' Fig. 6.1-4. Options 6, 7, and 8: Denatured Uranium Options with Converters and Breeders. The fuel cycle options assumed for the converters are as follows: (1) Low-enriched 235U/238U fuel, reactor operating on throwaway cycle; (2) Low-enriched 235U/238U fuel, reprocessing and 235U recycle permitted; (3) Pu/U fuel, reprocessing and Pu and 235U recycle permitted (LWRs only); (4) Pu/Th fuel, reprocessing and Pu and z33U recycle permitted; (5) Denatured 233U/238U/Th fuel, reprocessing and 233U and Pu recycle permitted. For the case of the FBR, the fuel options are (I) Pu/U fuel in core, Th in blankets, reprocessing and Pu and 233U recycle permitted; (2) Pu/Th fuel in core, Th in the blankets, reprocessing and Pu and 233U recycle permitted.

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. n Option 8: In this option, LEU (235U/238U) converters, denatured 235U and 233U converters, and denatur.ed 233U breeders are operated outside the energy centers and Pu/Th converters and Pu-Th/Th breeders (Pu-Th 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 plutonium into the inside reactors. With the reactors used, a heavy " ~ J I A - ~ O - ~ transmutation ~ ~ U ~ ~ rate is realized. Again, a denaturedbreeder is utilized in the system.
