Abstract : The general objective is to evaluate a clad carbide emitter, thermionic power module which simulates nuclear reactor installation, design, and performance. The module is an assembly of two series-connected converters with a single common cesium reservoir. The program goal is 500 hr cumulative operation at a power density of 7 watts/sq. cm. and an efficiency of 12%. This report describes progress made during the third program quarter, including: (1) Completion of fabrication of all clad fuel structures; (2) Completion of heat treatments and subsequent initiation of metallurgical evaluations of clad fuel specimens; (3) Completion of fabrication of all module components; and (4) Assembly of the module. At completion of module assembly, a rigorous leak-check revealed the presence of a very slight leak in one end of the collector insulator tube. (Author)
