Procedure for Determining Leachabilities of Radioactive Waste Forms

A new and improved procedure was developed for determining leachabilities of proposed radioactive waste forms.Finely divided glass samples are leached in flowing deionized water; leached ions are continuously sorbed on ion exchange resins to control ionic quality. Sorbed ions are eluted from the resin columns for atomic absorption analyses. Leachabilities measured by this procedure are lower and more consistent than those made in stagnant water without continuous ionic control.
