Activation Energies of Diffusion for I and Cs in Compacted Smectite

摘要

In the safety assessment (SA) of the geological disposal for a high-level radioactive waste, the role as a barrier function of the bentonite buffer is important to restrict the release of radionuclides (RN) from repository. Particularly, because the diffusion properties of RNs in bentonite directly control the release of RNs from the bentonite buffer, it is regarded as one of the important characteristics in the SA.
