Potential of Chemical-Absorption Heat Pumps for Thermoamplification in Nuclear Hybrid Energy Systems

摘要

The initial analysis of the hybrid chemical/absorption heat pump demonstrates the potential to make a significant contribution to the adoption of NHESs. The hybrid approach enables 300 ℃ heat to be upgraded to higher temperatures through an entirely thermal pathway with high exergetic efficiency and heat rejection occurring at reasonable ambient temperatures. The proposed system or any other coupling of CHP thermoamplifiers with nuclear reactors have not been previously reported in literature, despite the potential benefits. Ongoing work at Oregon State University, the University of Idaho, and Idaho National Laboratory is dedicated to developing a more detailed understanding of transient system dynamics, validation of models with subscale experimental data, and techno-economic analysis of the system at scale. To support ongoing work in the NHES field, validated component models will be translated into the Modelica framework to enable assessment of the system with other NHSE components.
