Abstract Scope |
Molten salt reactors (MSRs) operate at high temperatures but near atmospheric pressures. Depending on the design, unit operations that remove and/or process the cover gas will be necessary. The chemical potential of a species is a thermodynamic property and chemical potential gradients, among others, are dominate driving forces for mass transport. Therefore, it is important to understand the liquid-vapor equilibrium in an MSR system since that information, combined with kinetic considerations, must be known to properly model mass accountancy and the unit operations that are needed for off-gas system design and operation. Reported here are the results of mass loss Knudsen effusion coupled mass spectrometry measurements. The results are used to develop thermodynamic models that are coupled to liquid-vapor mass accountancy simulations using the Modelica based Transform code. Research sponsored by the U. S. Department of Energy and the Office of Nuclear Energy Advanced Reactor Technology Program. |
