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.

Future Climate Projections for Dry and Wet Condenser Cooling Options

This project will evaluate potential climate impacts in the northwestern United States from climate models and use those results to model plant performance using various cooling options. The results will be used to determine the range of plant performance and cost distributions to help understand the factors that need to influence the selection of a ultimate heat sink for a nuclear reactor in the region.

Horizontal Refueling and Remote Handling Design Review

The Remote Systems Group (RSG) at Oak Ridge National Laboratory (ORNL) will perform a three-stage design review focused on operations, the detailed design, and a failure modes and effects analysis. Their experience base is uniquely valuable to MIGHTR and In-Vesel Fuel Handling Machine (IVFHM) development. This project will mitigate the risk of operational complexity by reviewing a critical system.
