    • A system for removing thermal energy generated by radioactive materials is provided. The system comprises an air-cooled shell-and- tube heat exchanger, comprising a shell and plurality of heat exchange tubes arranged in a substantially vertical orientation within the shell, the heat exchange tubes comprising interior cavities that collectively form a tube-side fluid path, the shell forming a shell-side fluid path that extends from an air inlet of the shell to an air outlet of the shell, the air inlet at a lower elevation than the air outlet; a heat rejection closed-loop fluid circuit comprising the tube-side fluid path, a coolant fluid flowing through the heat rejection closed-loop fluid circuit, the heat rejection closed-loop fluid circuit thermally coupled to the radioactive materials; and the air-cooled shell-and-tube heat exchanger transferring thermal energy from the coolant fluid flowing through the tube-side fluid path to air flowing through the shell-side fluid path.
    • 提供了一种用于去除放射性材料产生的热能的系统。 该系统包括一个空气冷却的壳管式热交换器,它包括壳体和多个在壳体内基本垂直取向的热交换管,热交换管包括内腔,它们共同形成管侧流体路径 壳体形成从壳体的空气入口延伸到壳体的空气出口的壳侧流体路径,空气入口处于比出风口低的高度处; 包括管侧流体路径的散热闭环流体回路,流过散热闭环回路流体回路的冷却剂流体,与放射性物质热耦合的散热闭环流体回路; 以及将来自流经管侧流体路径的冷却剂流体的热能传递到流过壳侧流体路径的空气的风冷管壳式热交换器。
