Description

Studies at Hanford in the 1980s revealed the potential for actinides to form stable soluble complexes in alkaline media, simulating radioactive tank waste. Pu(IV) hydrous oxide and Pu(VI) solubility increased with hydroxide concentration, ionic strength, and aluminate/carbonate concentrations. Subsequent contacts between US and Russian researchers in 1993 led to a technical literature review of the chemistry of TRU and Tc in alkaline media; this review addresses oxidation states, solubility, speciation, redox reactions, electrochemistry, radiation chemistry, and separations in alkaline media. As an outgrowth, a program of fundamental and applied chemistry studies of TRU and Tc is being conducted at IPC/RAS ... continued below

As an outgrowth, a program of fundamental and applied chemistry studies of TRU and Tc is being conducted at IPC/RAS with US DOE support: solubility, redox reagents, coprecipitation, and radiation chemistry. This overview provides information on the Hanford Site tank waste system, US DOE technological needs, and IPC/RAS developments.
