This report presents an assessment of three different activities which led to the creation of TRAC-M, Version 3690. The first is the modernization of the old Transient Reactor Analysis Code for pressurized-water reactors (TRAC-P), the second is the integration of boiling water reactor (BWR) components from the TRAC-B code and the third is the integration of a spatial kinetics capability from the PARCS Code. The assessment shows that all three aspects of the modernization and integration have been successful.
