Effect of technetium on the NBL method of determining uranium: a joint effort with Oak Ridge National Laboratory

The assay of HTGR recycle fuel may involve the analysis of uranium which contains technetium-99. Methods of removing Tc from uranium samples are discussed. The best results were obtained by fuming the samples to complete dryness from a mixture of H$sub 2$SO$sub 4$ and HClO$sub 4$ in order to volatilize the Tc. (JSR)
