Abstract (en)
[origin: WO2011028165A1] The present invention relates to a method for long-term storage of at least one canister containing spent nuclear fuel, said method comprising the steps of: a) placing the canister (1) in a storage space (12) located below the ground water level (20); b) embedding the canister (1) in the storage space (12) in a buffer material (5) such as clay, for example bentonite clay, and/or sand, for example quartz sand; wherein the method also comprises the step of c) supplying water to the storage space (12) containing the canister (1) embedded in the buffer material (5), so that the storage space (12) is actively saturated with water at a rate of saturation exceeding the natural saturation process. The invention also relates to a device for long-term storage.
