Abstract : This study concentrated on the permeation evaluation of sample materials and the design of the converter. Sample materials were received and after a preliminary examination were evaluated for permeation. The mathematics of the investigation were reviewed and refined to assure accurate analyses. Testing techniques were developed. A control sample of molybdenum was evaluated to verify permeation rates of other investigators and the sensitivity of the equipment was established. Hydrogen permeation rates for four sample materials were determined, and, although hydrogen permeation does take place, it is at levels that can be controlled by known sorption and gettering processes. A converter for use with fossil fuel was developed employing materials compatible with cesium and designed to permit the substitution of the emitter barrier with material determined optimum by the evaluation program.
