High Level

The basic principles of incorporating high level radioactive waste into glasses, ceramics and glass composite materials (GCMs) are described. Current UK technology uses glass wasteforms for the products of reprocessing while some waste streams may be incorporated in ceramics and difficult or legacy wastes will require the development of other wasteforms many of which will be GCMs. Processingproperty- structure relations in novel wasteforms are described including the use of self-sustaining reactions to produce a composite ceramic wasteform based on TiC and Al2O3 from irradiated graphite and development of a GCM wasteform for immobilising spent zeolite sand filters.

Concrete Component

Many practical applications of concrete require adjustment of its properties. If concrete is used as casing for radioactive waste deposits, its main purpose is to mitigate radionuclide release and the mix design must conform to this requirement. In this article bentonite as a material with great sorption capacity is used as a concrete component. The main issue is to assess durability of designed mixtures. Therefore, the pore structure and hygric properties are investigated. The experimental results show that bentonite utilization in concrete mixtures leads to a significant growth of pore amount in the range of 0.01 to 1 μm and increase of water transport ability.
