Radioactive Waste Repositories

For many years, we have been the main workplace for the engineering and research support of the Deep Geological Repository project in Czech Republic. The development of this project is managed by the state Radioactive Waste Repository Authority - SÚRAO. We also provide development and technical support for the operation and modernization of near-shallow repositories.

 

Our projects and services

The research and development services for the Deep Geological Repository project include:

  • Assessing migratory properties of the rock environment and materials of the so-called near-field
  • Design and development of engineering barriers of the repository (corrosion, diffusion, chemical interactions, anaerobic environment)
  • Assessing the stability/degradation of engineering barriers in time and in interaction with the environment (under acid-free subsoil conditions, including in-situ experiments)
  • Evaluation of RAW properties and stability after treatment (in the form intended for storage, RAW - fixation matrix) such as leaching, strength, flammability and thermal stability, residual water content, long-term hydrolytic stability, and other properties
  • Environment modeling, study and modeling of physicochemical processes
  • Security scenarios, analyses, and evaluations
  • Design of ways and methods of communicating with the public on the acceptability of repositories
  • Design and optimization of project solutions for surface and deep repositories
  • Management and coordination of research projects involving more than one workplace, participation in international projects

Low- and medium-active wastes are deposited in so-called landfills. We provide development and technical support for their operation and modernization. Our activities are:

  • Assessment of migration in the rock environment and materials of the near-field
  • Evaluation of RAW quality and stability of the system RAW - solidifying matrix - storage package such as leaching, compressive strength, residual water content, long-term hydrolytic stability, flammability and thermal stability and other properties
  • Assessment of the stability / degradation of engineering barriers in time and in interaction with the environment (including in situ experiments)
  • Safety scenarios, analyses and assessments, draft the Waste Acceptance Criteria
  • Design and optimization of the disposal design solution (including waste handling and control)
  • Monitoring storage (releases and environment, pre-disposal monitoring)
  • Management and coordination of research projects involving more than one partner, participation in international projects

We provide service to both repository operators and regulatory bodies.
