MODIFIED DISSOLUTION AND COULOMETRIC TITRATION PROCEDURE FOR THE ANALYSIS OF PLUTONIUM-URANIUM MIXED OXIDE

摘要

A new procedure has been developed and tested at HEDL for the dissolution of mixed plutonium-uranium oxide samples used for analysis. The most important feature of the new procedure is the use of a perchloric acid fume step which completely removes the hydrofluoric and nitric acids used to dissolve the sample.
