This report presents the current status of metal-fuel models in the SAS4A accident analysis computer code. The SAS4A code has been developed to analyze the consequences of unprotected accidents in Liquid Metal Reactors (LMRs). It provides a detailed description of the thermal, hydraulic, and neutronic events that occur in the reactor core during the initiating phase of postulated accidents. A metal-fuel version of SAS4A is now available for scoping, whole-core analyses of severe, unprotected accidents in metal-fueled LMRs. This report describes the integrated, computational framework and the metal-fuel phenomenological models. A whole-core analysis of a severe, unprotected loss-of-flow accident in a low coolant-void reactivity-worth metal-fuel core is presented as an example of the current SAS4A metal-fuel capabilities. The needs for future development of the SAS4A metal-fuel models are also identified.
