Abstract : The development of a high-temperature, vaporfilled thermionic converter for application with a nuclear reactor for space-vehicle electrical power generation is described. Problems associated with the design and operation of a thermionic converter employing a UC - ZrC emitter, a cesium plasma for space charge neutralization, and a high-temperature collector ar described. Emitter fabrication techniques are also described. A test cell employing a cylindrical UC - ZrC emitter, which was pressure bonded to a tantalum sleeve, and a low-temperature copper collector, was fabricated and operated for 400 hours to provide experimental data. The emitter was operated at temperatures of the order of 2000 C while the collector temperature was maintained at 200 to 300 C. A conceptual design study for a thermionic power reactor incorporating the thermionic converter under development is also included. (Author)
