Radioactive Waste Repositories

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.
