This quarterly report is intended to provide a timely summary of the major activities being conducted in the Chemical Development Section of the Chemical Technology Division at the Oak Ridge National Laboratory (ORNL) during the period September-December 1995. The report summarizes ten major tasks conducted within five major areas of research and development within the section. The first major research area-Chemical Processes for Waste Management-includes the following tasks: Comprehensive Supernate Treatment, Partitioning of Sludge Compounds by Caustic Leaching, Studies on Treatment of Dissolved MVST Sludge Using TRUEX Process, ACT*DE*CON{sup SM} Test Program, Hot Demonstration of Proposed Commercial Nuclide Removal Technology, and Sludge Washing and Dissolution of ORNL Waste: Data for Modeling Sludge Science. The Comprehensive Supernate task is currently evaluating several sorbents in batch tests for removing strontium, technetium, and cesium from ORNL Melton Valley Storage Tank (MVST) supernatant solutions. Nine sorbents have been evaluated for removing strontium from MVST W-29 supernatant, and seven have been tested for technetium removal. All planned batch testing of cesium sorbents has been completed; however, additional cesium tests may be made as new sorbents become available. At the request of Hanford personnel, some batch tests were made to evaluate the effect on cesium distribution of selected sorbents which had been treated with an organic such as tributyl phosphate.
