Development of Sprayed Clay Technology
Original language description
The construction of a deep geological repository for the storage of spent nuclear fuel will require the use of several hundred thousand tonnes of natural swelling clay (bentonite). This material possesses excellent swelling and self-healing abilities, high levels of plasticity and allows minimal hydraulic conductivity. The main function of the bentonite sealant will be to limit water transport around the canister containing spent fuel and thus prevent the eventual potential release of radionuclides intothe biosphere. The highly compacted bentonite (buffer) around the canister will form one element of the multi-barrier sealing system in each of the individual deposition chambers. Compacted bentonite (backfill) will fill the access galleries following the closure of each section (a pre-determined number of deposition chambers) of the repository. The objective of the research being carried out at the Centre of Experimental Geotechnics is to develop technology for the application of backf
