Summary

This proceedings, based on an American Chemical Society symposium entitled 'Experimental and Modeling Studies of Actinide Speciation in Non-Ideal Systems', deals with the management and disposal of radioactive waste. More specifically, it concerns modeling and experimental approaches for actinide chemistry in high ionic strength media, including general aspects of actinide chemistry in high-level nuclear waste and environmental systems, and the special problems of actinide behavior in concentrated electrolytes and/or alkaline conditions.
