Abstract :
The use of thermoelectrochemical energy conversion for the development of modular radionuclide power devices (RPDs) of output electric power 0.5-1.5 kW and with efficiency exceeding 10-15% is discussed. Experimental RPD prototypes based on radionuclide thermochemical generators (RTCGs) of output powers up to 200 W have been developed, the efficiency being 12%. Methods of circulating the working medium within the RTCG module using arrangements to ensure the support due to the inert gas pressure and the support due to capillary forces under conditions of gravitational field have been investigated and are discussed. Manufacturing procedures for the module components have been developed and tested
