Abstract:

This report describes the continuation of work accomplished under an applied research program to develop a thermionic converter module suitable for liquid metal heating. The A-1198B converter, designed for operation in a liquid metal loop, was operated for more than 2400 hours during life test. A technique for bonding the converter to the liquid metal tubing was developed. Design and fabrication methods perfected in the development of the A-1198B led to the production of the first multiple-unit thermionic energy module. Designated the A-1274, the module consisted of three series-connected converters in a single vacuum-tight envelope using a common cesium reservoir. Modular techniques were extended with the production of a 10-converter unit, a complex structure containing many ceramic-to-metal and metal-to-metal seals. During the program, a number of detailed evaluations of techniques and materials, including cesium compatibility studies, were also made. Author
