DETERMINATION OF URANIUM IN 310 STAINLESS STEEL RIBBON-TYPE FUEL ELEMENT BY THE APPLICATION OF THE MERCURY CATHODE-LEAD REDUCTOR-POTASSIUM DICHROMATE METHOD
A simple, accurate method for the determination of the uranium content of 310 stainless steel ribbon-type fuel elements was developed. The sample is dissolved in a sulfuric and nitric acid solution, evaporated to fumes of sulfur trioxide, and then diluted with water. Interfering ions are removed by electrolysis in a Melaven-type, water jacketed, mercury cathode cell. The percentage of uranium is then determined by reducing the uranium in sulfurichydrochloric acid solution with a lead reductor, adding ferric chloride to the reduction solution, and titrating the resulting ferrous ion with standard dichromate. Diphenylamine sulfonate is used as the indicator. Statistical treatment of data obtained from the analysis of synthetic samples shows the standard deviation for the method to be 0.055% uranium dioxide. (auth)
