There has been increasing interest in the utilization of thorium fuel cycles in nuclear power reactors for the past few years because of economic, fuel utilization, and pro- 1 iteration resistance factors. Also, it appears desirable to maintain the ratio of thermal reactors to fast reactors at a high value in the long term because of economic and proliferation resistance features. The analysis performed here concludes that the practical, early utilization of thorium fuel cycles in power reactors requires commercialization of HTGRs operating first on stowaway fuel cycles, followed by thorium fuel recycle. In the longer term, thorium utilization involves use,of thorium blankets in fast breeder reactors, in combination with recycling the bred 233U to HTGRs (preferably), or to other thermal reactors.
