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.

Real-Time Generation Risk Assessment (GRA) Model for Commercial Nuclear Power Plant

Entergy will partner with Oak Ridge National Laboratory (ORNL) to implement real-time Generation Risk Assessment (GRA) modeling to address these issues. ORNL’s unique experience in implementing GRA models combined with the use of their Operational Performance Risk Assessment (OPRA) software will be used to integrate the model with real-time data. Entergy will roll out the model at one of its operating plants an if successful look to expand to other plants in their fleet.
