22nd January  2014

Large Chemistry Lecture Theatre
Cardiff University

The lecture will discuss some of the significant scientific challenges that have had to be considered in the context of the geological disposal of nuclear waste. Attention will be focused on the behaviour of the so-called engineered barrier and in particular on the clay buffer that will be used to contain the waste containers.

On the Geological Disposal of Nuclear Waste

Advances achieved in relation to the thermo/hydro/chemical mechanical behaviour of the soil will be considered. An attempt will also be made to present an overview of the advances made worldwide. Some of the remaining challenges will also be discussed.
