Various nuclear characteristics of two-region spherical homogeneous reactors have been computed in order to provide information for the design of HRE-3. Equilibrium isotope concentrations were established using an ORACLE code, and a two-group model was used to obtain critical concentrations and flux distributions. Breeding ratio is plotted as a function of reactor size, blanket thorium concentration, and other design and operating parameters, and the time required for a demonstration of breeding is discussed. Tables of results, including neutron balances, are given for selected reactors. A number of relations are presented for estimating the effects of fission products, copper, corrosion products, H₂O, and the core tank on breeding ratio.
