Thermogravimetric Analysis of IMSR Fuel Salt Simulants

Terrestrial Energy will partner with Pacific Northwest National Laboratory (PNNL) using their expertise in thermogravimetric analysis to analyze the IMSR fuel salt. This project will help determine what chemical species are present in the fuel salt vapor as a function of temperature and partial pressure, whether the fuel salt decomposes at elevated temperatures, and the kinetics of fuel salt vaporization. The work will support the optimization of the reactor components in the IMSR Core-unit as well as the overall design.

Chemical Method Development for Quantifying Oxygen in Beryllium Salts, Kairos Power

The goal of this project was to develop a method for analyzing the oxygen content using a commercial inert gas fusion analyzer. This included the development of a calibration curve for the method, quantification of its performance, and testing on FLiBe samples from several sources, including ORNL-produced FLiBe as well as Kairos Power Flibe.
