Molten Salt Nuclear Graphite Qualification Plan

Natura will partner with Oak Ridge National Laboratory (ORNL) to develop a graphite qualification plan and identify performance characteristics and development plans to design, approve, and perform graphite irradiations with fuel-bearing salts. The plan will look at utilizing the High Flux Isotope Reactor (HFIR) at ORNL which would allow for rapid neutron irradiation of graphite (7-10 dpa per year) in a future irradiation test outside of the voucher scope. The project will also include the development of fuel-bearing, molten salt irradiation capsules to support the future irradiation test.

Radiation Test of Smart Electric Cable for Nuclear Power Plants

AiMiLi will partner with Pacific Northwest National Laboratory (PNNL) to access the Accelerated and Real-time Experimental Nodal Assessment (ARENA) Cable Test Bed and High Exposure Facility (HEF) gamma irradiation capabilities. These facilities can simulate adverse power plant environments in a testing environment.

Reference Data for Determination of Carbon and Oxygen Content in TRISO Fuel Kernels

Standard Nuclear is developing alternative methods to assess the carbon and oxygen content in the fuel kernel. They will partner with Oak Ridge National Laboratory (ORNL) to perform LECO testing in the Low Activation Materials Development and Analysis (LAMDA) laboratory to help baseline and calibrate the method. By developing an alternative method for assessing carbon and oxygen content in TRISO fuel kernels, this project will reduce the cost and inefficiencies associated with current destructive testing methods.

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.

Development of Analytical Techniques for Trace Impurities in 2LiF-BeF2, Kairos Power

Kairos will partner with Pacific Northwest National Laboratory (PNNL) to extend measurements of dissolved oxygen and corrosion products in FLiBe to the full range of relevant/significant impurities, as well as incorporating the measurement methods into their quality assurance program/practices. Refinement of analytical methods for species in salt that impact system operation will enable Kairos to continue along the aggressive timeline for near term nuclear demonstration and commercial deployment.

Research Evaluates Transitioning from Coal to Nuclear Energy

October 2024 – Researchers are engaging directly with communities to learn more about local opinions and how to build social and cultural metrics into their energy-planning analysis. That’s work that’s also being done at ORNL, where the Gateway for Accelerated Innovation in Nuclear (GAIN) works with individual sites and utilities to run economic analyses and provide decision-making resources.

Independent Assessment of a Novel Heat Exchanger Concept for Open-Air Brayton Cycle, Nano Nuclear Energy

Nano will partner with Idaho National Laboratory (INL) to perform an independent evaluation of the heat exchanger design. This will include the development of a computational model of the heat exchanger to help analyze the design and confirm certain attributes that are critical to the reactor operations.

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.
