Abstract

Abstract

In order to meet the energy conversion requirements of small fluoride cooled high temperature reactor (FHR), an efficient, compact and water-free cooling power conversion system is developed. In this paper, the thermoelectric conversion efficiency, exergy efficiency and exergy loss distribution of supercritical carbon dioxide (SCO₂), air, argon (Ar), nitrogen (N₂) and xenon (Xe) in different Brayton cycle configurations are compared. It is found that SCO₂ Brayton cycle has the highest thermoelectric conversion efficiency and exergy efficiency compared with other working medium cycles, and its structure is more compact, easy to miniaturization and modularization, and has more advantages in coupling with small fluorine salt cooled high temperature reactor; the configuration of SCO₂ Brayton cycle is optimized, and the optimal cycle configuration mode matching the small fluoride cooled high-temperature reactor is obtained, which constitutes an inherently safe modular small fluoride cooled high-temperature reactor thermoelectric conversion system, providing a new research idea for energy utilization in the west.
