Abstract

The main component of this study was the behaviour of radioactive waste, which is particularly affected by the temperature of the glass or leaching agent and the stability of a gel layer formed on the leached glass surface. The selection of the materials used in high activity waste containers and technological structures was based on criteria of corrosion resistance to a hot leach, mechanical strength or stability, technical workability and cost efficiency. Other aspects under investigation were the geological storage medium which must satisfy particularly complex requirements, and large-scale movements of the salt dome, including thermal expansion, which are also offset by the creep behaviour because of their relatively long duration. Also indicated and discussed are the consequences which can already be discerned in respect of: - waste specification - parameters for the storage field and total final repository - the input sequence and which arise out of integrity requirements relating to: - waste - containers - the salt environment of a heat source - cavity structure - and total rock formation.
