DOE has engaged the IPC/RAS to study the fundamental and applied chemistry of the transuranium actinide elements (primarily neptunium, plutonium, and americium) and technetium in alkaline media. This work is supported by DOE because the alkaline radioactive wastes stored in underground tanks at DOE sites (Hanford, Savannah River, and Oak Ridge) contain TRUs and technetium, and these radioelements must be partitioned to the HLW fraction in planned waste processing operations. The chemistries of the TRUs and technetium are not well developed in this system. Previous studies at the IPC/RAS centered on the fundamental chemistry of the TRUs and technetium in alkaline media, and on their coprecipitation reactions. During FY 1996, further studies of fundamental and candidate process chemistries were pursued with continuing effort on coprecipitation. The technical liaison was established at Westinghouse Hanford Company to provide information to the IPC/RAS on the Hanford Site waste system, define and refine the work scope, publish IPC/RAS reports in open literature documents and presentations, provide essential materials and equipment to the IPC/RAS, compare IPC/RAS results with results from other sources, and test chemical reactions or processes proposed by the IPC/RAS with actual Hanford Site tank waste. The liaison task was transferred to the Pacific Northwest Laboratory (PNNL) in October 1996.
