Our key strengths are in synthesising relevant information and developing and applying conceptual and mathematical models for the key processes that contribute to the long-term safety of geological disposal including:

• synthesis of data from site investigations, in-situ and laboratory experiments;
• conceptual and mathematical modelling of groundwater flow and radionuclide transport in porous and fractured rocks;
• near-surface hydrology modelling and its coupling to deep groundwater flow;
• reactive geochemical transport modelling of water-rock-radionuclide systems;
• multiphase flow of groundwater / gas and groundwater / non-aqueous phase liquid systems;
• thermal evolution modelling including coupling to hydrogeological, mechanical and chemical processes;
• conceptual modelling and quantification of mechanical processes affecting the long-term stability of geological disposal facilities;
• data synthesis, understanding and modelling of radionuclide speciation, solubility and sorption;
• impacts of complexants, colloids and microbes on radionuclide transport;
• analysis of natural analogues providing supporting safety aruments; and
• synthesis of data, conceptual understanding and modelling to provide support to environmental safety cases and an interface to performance assessment.
