Resum
Sand/bentonite mixtures are considered as buffer material in low and medium radioactive waste disposal schemes. While the bentonite provides low permeability and swelling capacity, the sand is intended to improve mechanical stability and to reduce the amount of bentonite required. One of the requirements of the buffer is to ensure the isolation of the gas-emitting waste. The pressurized gas may migrate towards the host geological media through several mechanisms (dissolution, two-phase flow, pre...
