The aim of the new concept of the LILW repository is to improve and optimize safety of the construction, the main role being played by the repository protective (lining) systems. The repository protective systems consist of a cover layer and a bottom layer system of lining and drainage materials. This concept has not yet been used at LILW repositories.
The new concept represents a considerable improvement over the previous types of the LILW repository – it is designed with a complete bottom and cover protection system of layers that were not previously applied to LILW repositories. The cover protection system of the new landfill concept protects against low temperatures and freezing, the ingress of rainwater into the landfill and other external influences on the landfill body. The basic protection system completely protects the soil and groundwater from radionuclide pollution.
This innovative new concept for a constructive solution of a near-surface repository enables long-term isolation of LILW, much improved compared to previous solutions. Improvements in repository protection systems provide additional and significantly improved protection for the environment and biota.
