[en] A program that will quantify the capability of the GCFR on any fuel cycle that appears to be politically realistic is outlined. Preliminary calculations are performed and the approximate breeding ratio, specific power, and mass flows are determined. Some sensitivity studies are made to estimate the value of improved fuel and structural materials. A number of possible fuel strategies which consider systems of reactors are superficially reviewed and related to future energy needs. Fuel cycle strategies that attempt to meet future energy needs while not increasing the potential for weapons proliferation are suggested, and the advantages of the GCFR in such strategies are discussed
