Clay barriers in radioactive waste disposal
Deep geological is one of the preferred options for the disposal of high level radioactive waste. In most designs, the canisters placed in drifts or boreholes are surrounded by an engineered barrier usually made of compacted swelling clay. The barrier undergoes severe heating from the canisters and hydration from the host rock. In this situation a number of interacting thermal, hydraulic and mechanical phenomena arise. The behaviour of an engineered barrier in a particular disposal scheme has been analysed by coupled THM analyses. The results of the computations allow a more detailed examination and a better understanding of the complex transient phenomena occurring in the near field.
