A comprehensive research investigation has been undertaken to improve understanding of the potential role of colloids in the context of disposal and storage of low level and intermediate level waste immobilised in cement. Topics which have been investigated include: (a) the study of the formation and characteristics of colloids in cement leachates; (b) the effects of the near-field aqueous chemistry on the characteristics of colloids in repository environments; (c) colloid sorption behaviour; (d) interactions of near-field materials with leachates; (e) characteristics of near-field materials in EC repository simulation tests, and (f) colloid migration behaviour. These experimental investigations provide data and a basis for the development of transport models and leaching mechanisms, and thus relate directly to the part of the Task 3 programme concerned with migration and retention of radionuclides in the near field.
