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.

Improvements to Passive Heat Removal Systems in SAS4A/SASSYS-1, ARC Clean Technology

For this project, ARC will work with Argonne National Laboratory (ANL) to enhance the SAS modeling capabilities for passive heat removal systems, including the generic RVACS model and the DRACS heat exchanger models. These enhancements will enable ARC to recover safety margins and have a better representation of the system’s response during long-term cooling events.

Dynamic Natural Convection System, Dynac Systems LLC

This Gateway for Accelerated Innovation in Nuclear voucher paired DYNAC Systems with Idaho National Laboratory to evaluate the company’s Dynamic Natural Convection (DNC) system.

On-Line Lead/Water Heat Exchanger Sensor/System Feasibility, Hydromine

This project will leverage Pacific Northwest National Laboratory’s experience with high-temperature ultrasound to demonstrate feasibility for OLSHM of the Hydromine lead-cooled reactor heat exchanger for cracks and corrosion.

NEAMS [Nuclear Energy Advanced Modeling and Simulation] ThermalFluids Test Stand for Fluoride-Salt-Cooled, High- Temperature Reactor Development, Kairos Power LLC

Argonne National Laboratory (ANL), Idaho National Laboratory (INL), and Kairos Power, LLC partnered to implement a multiscale thermal-fluids hierarchy analysis methodology for Kairos’ fluoride high-temperature reactor (FHR). The project demonstrated Kairos Power’s design optimization process for the heat exchanger, a vital component of the reactor’s design.

High Efficiency Heat Exchanger for High Temperature and High Pressure Applications, CompRex, LLC

The objective of this project was to evaluate different heat exchanger designs specified by CompRex using a lab-developed Fortran code to model heat exchange and pressure drop performance.
