Geological Disposal of Radioactive Waste

Studying the behaviour of rocks and fluids deep underground

Radioactive waste generated by the nuclear energy industry may be disposed of in deep underground geological formations, with international efforts underway studying methods and techniques from geological isolation from the ecosystem and surrounding environment.

A complete understanding of the complex phenomena of fluids, heat, mass transfer and geochemical reactions occurring deep underground is often required for the selection, construction, operation, and long-term closure of a nuclear disposal site.

We provide modelling and simulation services relating to this complex phenomenon using several well-tested and reliable numerical simulators.

Examples of our experience

  • Improvement of a high accuracy finite element seepage flow analysis code
  • Investigation and review of the latest status of European geological disposal research projects
  • Sensitivity analysis focusing on redox conditions during tunnel excavation
  • Benchmarking of groundwater flow analysis codes
