The aim of Beacon is to develop the understanding of fundamental processes that lead to material homogenisation as well as to improve capabilities for numerical modelling. In earlier assessments of bentonite EBS the mechanical interaction between the installed bentonite components has been neglected and an ideal final state has generally been assumed. Key features of the project are 1 re-evaluation of the available knowledge to extract the crucial data to compile the qualitative and quantitative data and to enhance the conceptual understanding. 2 Enhanced robust and practical numerical tools based on a good scientific understanding which have the expected predictive capabilities regarding the evolution of engineered barriers and seals. 3 A developed database with .
