Abstract: The main purpose of the SASSYS code is to analyze the consequences of failures in the shutdown heat removal system of a liquid metal cooled fast breeder reactor. The code is also capable of analyzing a wide range of transients, from mild operational transients through severe hypothetical core disruptive accidents. Some important features of the code include a detailed multi-channel core thermal hydraulics treatment with transient flow redistribution between assemblies, a model for boiling of sodium in the fuel assemblies, a general thermal hydraulics treatment for an arbitrary arrangement of components in the primary and intermidiate heat transport loops, and a fast-running steam generator model. The numerical methods mainly use semi-implicit or fully implicit time differencing to provide large time step sizes and rapid calculations.
