Deep Fission will partner with Idaho National Laboratory (INL) to enhance its thermal hydraulics infrastructure using RELAP5-3D modeling. INL has unique expertise in developing thermomechanical and thermos-hydro-mechanical models in deep geological repositories for used nuclear fuel and geothermal applications involving deep hole drilling and heat extraction.
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.

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.

The casting, processing, and shipping of HALEU alloys, like those being developed by Lightbridge, require the ability to experiment with higher temperatures in a facility that can perform these functions. The goal of this project was to identify an appropriate casting method (i.e., crucible and coating combination) that results in an acceptable impurity concentration in the as-cast ingot.

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.

Kairos Power is a nuclear energy technology, engineering, and manufacturing company singularly focused on the commercialization of the fluoride salt-cooled, high-temperature reactor (FHR). To simulate the core thermal hydraulic behavior, researchers employ simplified empirical correlation-based porous media and heat transfer models. For different operation and accident scenario conditions, Large Eddy Simulations (LES) can produce numerical benchmark data that capture local velocity and temperature effects. This can be used to further understand the different modes of heat transfer in an FHR core. Under this GAIN voucher, Argonne National Laboratory provided Kairos Power its expertise in LES and turbulence modeling and made available its advanced computational resources.
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.
