The performance potential for (U,Th) fueled liquid metal fast breeder reactors is determined over a wide range of reactor core designs. A generic evaluation is made of (U,Th) oxide, metal, carbide, and nitride fuel performance in 1000 MWe size systems, which includes nuclear, thermalhydraulic, and mechanical design analysis. The following parameters affecting system performance, safety, and reliability were studied: breeding performance, fuel inventories, fuel burnup, sodium void reactivities, Doppler coefficients, duct stresses and lifetime, cladding and duct core-wide temperature distributions, and cumulative damage fraction. Sensitivity coefficients for the nuclear data of the principal constituents of a representative /sup 233/U-/sup 232/Th oxide fueled LMFBR were generated. Generalized perturbation coefficients for several reactor parameters were computed for a homogeneous one-dimensional spherical model. Reference designs were selected for each (U,Th) fuel type and a complete detailed design analysis included the areas of nuclear design, thermal-hydraulic design, and mechanical design.
