This paper describes investigations that have been made with the Schuller-Gollnow water-cooled hollow-cathode tube for the purpose of using it as an analytical source to analyze fuel materials employed in nuclear reactors. A number of unirradiated normal and enriched uranium alloys have been tested with the above tube using a 21-ft, Wadsworth, Jarrell-Ash grating spectrograph and photographic plates. Results obtained for molybdenum, ruthenium, rhodium, and palladium, in the range of 2.5, 2.0, 0.3, and 0.2% respectively, compare favorably with the point-to-plane technique.
