Heat Exchanger Evaluation

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.
