Qualification of Glass Bottles for Accurate Control of the Composition of Uranium Dioxide Powder Samples

摘要

An earlier report demonstrated the precautions which must be taken to prevent or control the potential changes in the composition of small analytical samples of 10-20 g of UO sub 2 powders because of moisture pick up or air oxidation between the time of sampling and analysis. The study served also to qualify the batch of glass bottles which were used for all safeguards inspection samples. The present report describes the results of the qualification of the new type of bottles. It presents also the refinements introduced in the correction procedure following the experience gained in actual practice. 6 references, 4 figures, 5 tables. (ERA citation 12:032590)
