Analysis of NuCycle® Flowsheet for Waste Stream Characterization, Curio Solutions

Curio will partner with Pacific Northwest National Laboratory (PNNL) to conduct an analysis of the NuCycle® flowsheet that will allow the generation of quantities and classification of anticipated waste streams and recommendations on waste forms most suitable to sequestering the generated waste streams. Results of the project would be used to determine the approach to managing waste from a pilot demonstration of NuCycle® to be performed in 2027.

Heat Exchanger Evaluation, NuCube Energy

NuCube will partner with Idaho National Laboratory (INL) to receive assistance in computational analysis of the heat exchanger design. INL has developed a code to optimize high temperature heat exchangers for both installation and operating costs and has validated that code for conventional shell and tube heat exchangers. This analysis will allow NuCube to assess the performance of the heat exchanger and support an optimized design prior to finalization of the detailed design and fabrication to support a demonstration project.

Three Mile Island

Three Mile Island, Notorious in Nuclear Power’s Past, May Herald Its Future

The concrete cooling towers that rise from a sliver of land south of Pennsylvania’s capital became symbols nearly a half-century ago of the risks of nuclear energy.

Now, a plan to restart one of the two reactors at Three Mile Island is at the leading edge of efforts to greatly expand the country’s reliance on atomic fission to meet the growing power demands of homes, businesses and data centers.

Development of Oxygen IR Calibration Standards for High-Purity Chloride Salts, Sigma-Aldrich

Idaho National Laboratory (INL) is only one of two labs that can test the oxygen content in chloride salts. MS will partner with INL to verify alignment of test results between MS and INL regarding oxygen content of very high-purity chloride salts utilizing oxygen analyzers, identify, capture, and document best practices into a preliminary framework for a standardized test method and down-select appropriate materials and certification specifications for chloride salt reference standard(s).

Independent Analysis of Antares R1 Core Design, Antares Nuclear

Antares will partner with Oak Ridge National Laboratory (ORNL) to perform an independent, technical audit of Antares R1. ORNL’s Reactor Analysis Group will verify design calculations, including core neutronics and thermal hydraulics. This project will yield high confidence that hardware test campaigns predicated on neutronics data are valid, allowing Antares to move through test stages to a fueled demonstration of the system.

Project SparkHub: Nuclear-Powered Data Center Development, Advanced Nuclear Advisors

To help get ANA’s Project SparkHub off to a quick start, ANA will partner with Oak Ridge National Laboratory (ORNL) to use the OR-SAGE tool to perform site screening and down select a number of sites that could be amenable to siting nuclear facilities. The sites will also be located in regions where there is strong incentive to build data centers. After the project, ANA will continue work and begin licensing activities to obtain an Early Site Permit on a technology-neutral basis to support development of the site.

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.

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

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.
