The mercury cathode --lead reductor --potassium dichromate method previously used for the determination of uranium in 310 stainless steel ribbon- type fuel elements was improved. The sample is dissolved in perchloric acid, electrolyzed in a mercury cathode cell, and reduced by a lead reductor. The resulting tetravalent uranium is then titrated with standard ceric sulfate, using ferroin as the indicator. By employing this method, the over-all time of analysis was reduced by approximately four hours, and the precision of the determination was increased from a standard deviation of 0.055% to a standard deviation of 0.029% uranium dioxide.
