Molten Salt Thermal Properties Working Group

The Molten Salt Thermal Properties Working Group was organized in 2020 by General Atomics Center Director Professor Ted Besmann and Dr. Jake McMurray of Kairos Power to help address communication issues stemming from rapid expansion of research on molten salts as heat transfer media and nuclear fuel.

About the MSTPWG

The swift growth in interest in molten salts has substantially increased the technical community concerned with the various thermal properties of the materials. This has left many of those in the field unaware of the activities of others, with missed collaborative opportunities, possible duplicative efforts, and lack of awareness of useful new data. The Molten Salt Thermal Properties Working Group was therefore established to help address these issues.

The group is made up of an informal/ad hoc set of researchers working on molten salt thermochemical / thermophysical properties.  Members are self-selected, only needing to provide their contact information to join. It is specifically targeted at the sharing of computational, experimental, and modeling methods and results for the following:

  • Fundamental phase equilibria determinations (e.g., solidus/liquidus, eutectics, etc.)
  • Determinations of enthalpy of formation, heat of transition/fusion, heat capacity, etc.
  • Vapor pressures
  • Viscosity
  • Thermal conductivity

Our activities include:

  • Organizing periodic workshops
  • Engaging in round-robin measurement studies
  • Circulating job searches
  • Fostering collaborations

 

Previous Workshops

The November 2021 Virtual Workshop over the 15th, 16th and 17th, had 130 registrants representing DOE, the NRC, 7 national labs, 8 companies and 18 universities.  It included 27 programmatic and research presentations, and 14 posters.  We also had a very successful “collaboration” event with 6 virtual tables where participants could discuss specific topics and travel from table to table to engage in informal discussions.

A strong interest in understanding best practices and limitations of first-principles and atomistic modeling encouraged this focused workshop hosted by the University of South Carolina, Nov. 10-11, 2020 of about 85 participants who heard program overviews and engaged in extended discussion.

Thank you to all who provided presentations and attended the virtual workshop hosted by the University of South Carolina July 14-15, 2020. We had roughly 134 participants who heard program overviews, tutorials and brief presentations on activities from 22 institutions.
