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.

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.
