Thermogravimetric Analysis of IMSR Fuel Salt Simulants, Terrestrial Energy

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.

Metatomic Molten Salt Immersed Hydrochlorination Subsystem Characterization, Metomic

Savannah River National Laboratory (SRNL) will provide the requisite expertise and spent fuel handling capability to enable the laboratory scale assessment and demonstration. The data generated at laboratory scale would provide confirmation of feasibility and basis for scaling to an industrial scale capability.

Assessment of NuScale SMR Steam Heat Augmentation for Chemical Plant Decarbonization, NuScale Power

NuScale will partner with Oak Ridge National Laboratory (ORNL) to perform a techno-economic analysis of a NuScale plant with a novel heat augmentation system for application to a commercial scale chemical production facility to help understand the functional requirements for the system and determine best ways to integrate with the facility.

ICP-MS for Analysis of Lithium Isotopic Ratios in Materials Highly Enriched in 7Li, Kairos Power

The goal of this project would be to evaluate performance capabilities of instruments and develop standardized hardware configurations and operating procedures to analyze lithium isotopic ratios to support production of Flibe coolant that is highly enriched in 7Li.

PIE-Enabled Study of Aqueous Corrosion & Zr Hydriding in Cr-Coated Cladding, Westinghouse

The objective of this project is to enhance understanding of aqueous corrosion and hydrogen transport for Zr hydride formation in Cr-coated claddings, as a function of the Cr-coating deposition method (cold spray (CS) or physical vapor deposition (PVD)).

Post-Irradiation Examination to Quantify Irradiation-Induced Bowing of SiGA® Silicon Carbide Composite Structures, General Atomics

This project will address first-of-a-kind (FOAK) experimental post-irradiation examination (PIE) of irradiation-induced bowing response in SiC-SiC structures.

High Temperature Neutron Flux Detector – Reactor Testing, Ultra Energy

Ultra has developed a prototype detector but to complete the anticipated testing program for the prototype detector and demonstrate suitable operation at reactor flux levels, the detector requires testing at fluxes equivalent to those typically seen in power reactor operation (1E10 – 1E11nv).

2022 Molten Salt Reactor Workshop

This workshop will focus on multiple topics, including overviews of US Department of Energy (DOE) and US Nuclear Regulatory Commission (NRC) MSR released activities and overviews of the US DOE Office of Nuclear Energy (NE) MSR technology development and advanced modeling and simulation activities.

Criticality Safety Evaluation of NuCycle™, Curio Solutions

The project will evaluate the criticality safety limits of the conceptual equipment designs for NuCycle™.

Elementl Power Siting Evaluation, Elementl Power LLC

Elementl is evaluating dozens of locations in the U.S. for siting suitability of advanced reactor technologies.
