Radioactive waste

Petrographical, microchemical and fluid inclusion studies of the most recent mineralization in hydrogeologically active fractures provide an insight into the long-term evolution of repository groundwater systems in response to Quaternary climate changes. This example is from the deep groundwater system at Dounreay, Caithness

The team carries out multidisciplinary research on a number of topics important to the future safe geological disposal of radioactive waste including

  • state-of-the-art studies on the movement of fluids (gas, water, solutes) through mudrocks
  • coupled deformation behaviour in particular the engineered damaged zone around repository openings
  • the role of biofilms and particle transport (colloids/nanoparticles) in the movement of radioactivity through the geological environment
  • understanding past and predicting future groundwater flow paths in response to drivers such as climate change, uplift and tectonics
  • impact of climate change, uplift and tectonics on the physical, hydrogeological and geochemical stability of the repository environment
  • application of natural analogue studies to process understanding and the long-term evolution of geological repository systems

We undertake work on behalf of a number of national and international waste management organisations and have provided geological data and interpretations concerning the safe storage and disposal of radioactive waste for more than 40 years.
