|Abstract:||With the objective to make high temperature process heat applications a reality already in the short- and medium-term, this paper investigates the feasibility, efficiency and R&D aspects of a medium-temperature CO2-cooled reactor based on modular HTR technology for combined electricity and high temperature process heat applications. A concept is proposed here that is based on a primary cooling circuit with a top cycle temperature of 640C. A secondary reverse Brayton cycle acts as a heat pump by compressing gas up to the desired temperature level depending on the application and on evolving material limits. The configuration is completed by a bottoming power conversion cycle that produces at least the electrical or mechanical power for the compressor in the heat pump.|
