研究了一种基于安瓿型发电元件的热电发电机模块化结构的空间核动力系统概念。高温热管（氘-锂）用于从反应堆堆芯移除热量;从堆芯到管道的热接收表面的热传输是通过辐射完成的。热量通过中温（钒钾）热管排出。以碳化铀为燃料、碳-石墨材料为结构材料的快堆是一个大系列。热电发电机由使用金属分流器作为极间绝缘的最大限度统一的发电元件组成，根据对空间核动力系统基本元件的热物理和质量/尺寸特性的分析，估计了20-200千瓦大系列的质量/尺寸特性。3图，3参考文献。
A concept for space nuclear power systems with modular construction of the thermal electric generator based on ampul-type electricity-generating elements is examined. High-temperature heat pipes (molybdenum-lithium) are used to remove heat from the reactor core; heat transmission from the core to the heat-receiving surface of the pipes is accomplished by radiation. Heat is removed by means of medium-temperature (vanadium-potassium) heat pipes. Fast reactors with uranium dicarbide as fuel and carbon-graphite materials as the structural materials are examined for a large series. The thermoelectric generator consists of maximally unified electricity-generating elements using a metallic shunt as the interelectrode insulation.The mass/size characteristics of a large series 20–200 kW are estimated on the basis of an analysis of the thermophysical and mass/size characteristics of the basic elements of space nuclear power systems. 3 figures, 3 references.
