FIELD: space-based thermionic power units depending for their operation on thermionic conversion of heat energy to electric power.
SUBSTANCE: proposed looper designed for testing thermionic power-generating assemblies and can be used for optimizing them has housing accommodating heat dump system, as well as cesium steam supply and cesium circuit provided with electric heaters. Heat dump system is designed to accommodate thermionic power-generating assembly to be tested. Heat dump system outer surfaces are cooled down with research reactor water. Cesium circuit is designed for communication with electrode clearances of thermionic power-generating assembly and with reactor test facility evacuation system. Liquid cesium accumulation tank installed outside of housing and cooled with research reactor water communicates with cesium circuit through controlled and heated shut-off valve. This tank can be sealed and disconnected from housing.
EFFECT: reduced radiation hazard during looper discharge for next investigations, facilitated post-test recovery of loopers.
