Successful modeling and simulation of molten salt reactors (MSRs) requires quality thermodynamic and thermophysical data for the working fluid. A goal of the Molten Salt Reactor Campaign is to develop a
quality-controlled database of these properties that will be available for a multitude of different salt types. Furthermore, properties shall be defined in a standardized format that can then be used by reactor modeling and analysis tools. This report details work done to develop an approach for integrating salt properties into a MSR analysis tool. This activity required defining a format for thermophysical properties that could be produced from salt data delivered by Argonne National Laboratory (ANL) and which could be read into a reactor analysis tool. The reactor analysis tool used for this activity was the Consortium for Advanced Simulation of Light Water Reactors-developed tool, VERA. The changes implemented in VERA to accept the thermophysical properties file are discussed and tested and the process of reading thermophysical properties into VERA for a MSR simulation is demonstrated. In addition to being able to get fluid properties into the simulation tool, it is also necessary that a process exists for adding new salt data to the salt database. The NEAMS Workbench is being expanded with a new package called ThermPhys that will provide a user interface for adding new salts to the database while performing input validation and ensuring data quality.
