The SAS4A accident analysis code was developed at Argonne National Laboratory for the analysis of severe hypothetical accidents in liquid-metal reactors. The code was initially developed for the analysis of oxide-fueled cores. Due to the recent interest in metal-fueled cores in the US, a metal-fuel version of SAS4A is being developed. This version of SAS4A has been used for the analysis of the M7 experiment in which two metal-fuel pins were subjected to a transient over-power event. The analysis described in this paper is the first experiment analysis using the integrated metal version of SAS4A and provides a description of the experimental sequence from fuel pin heat-up and melting to the onset of the in-in fuel motion, cladding failure, and postfailure ex-pin fuel relocation. The computed fuel relocation results are compared with the experimental observations, and an interpretation of the sequence of events is presented. The M7 experiment was performed in the Transient Reactor Test Facility (TREAT).
