“…Moreover, The helium production was seldom impacted by the working temperature of the lithium HP. Wang et al (2022) created a mathematical and physical model for how NCG affected the heat transfer of a lithium HTHP and developed a transient analysis code, HPTAC-NCG. During the steady-state operation, the temperature drop in the NCG region increased with the NCG volume fraction, and the HP average temperature increased, which could cause overheating and drying out at the evaporator bottom.…”

Heat pipe cooled reactors (HPCRs) have broad application prospects due to their advantages, such as high power density, compact structure, lower cost, and easy modular assembly. Numerous countries have engaged in extensive research and development of HPCR conceptual designs. The heat from the reactor is removed by high temperature heat pipes (HTHPs), which generally employ alkali metals as the working fluid, such as potassium, sodium, and lithium. Understanding the thermal-hydraulic performance of HTHPs is essential for the safe and efficient operation of a reactor. Therefore, the objective of this paper is to provide a comprehensive review of HPCR conceptual designs developed by various countries in recent years. The research progress of HTHPs on flow and heat transfer performance is reviewed, with an emphasis on both transient and steady-state characteristics. Research progress, as well as the issues that need to be focused on in future research, are discussed in detail.
