Several chemical processing flowsheets are under development for the separation and isolation of the actinide, lanthanide, and fission product streams in spent nuclear fuel. The objective of this research is to investigate the conversion of these product streams to solid forms, typically oxides, which is essential for waste disposition and recycling of product fractions back into transmutation fuels or targets. The modified direct denitration (MDD) process, developed at Oak Ridge National Laboratory in the 1980s, is employed as a methodology to facilitate the conversion of spent fuel products into powder forms that are suitable for direct fabrication into recycle fuels. Currently, two systems, a glove-box-contained MDD system and a fume-hood-contained system, have been assembled at ORNL to test the co-conversion of uranium and mixed-actinide products. Preliminary results indicate that a successful conversion of the product has been achieved, evidenced by a free-flowing powder and clear condensate. The activities outlined focus on the conversion of the first products generated from the processing of spent nuclear fuel in the ongoing Coupled End-to-End Demonstration at ORNL.
