Explore the critical relationship between yield strength and permeability in mudstones through this 52-minute research presentation by Dr. Isabel Ashman from the University of Liverpool. Learn about the geological requirements for radioactive waste disposal facilities and understand how stress conditions affect fluid pathways in potential host rocks. Discover the experimental methodology used to map yield curves of Low Strength Sedimentary Rocks, including triaxial deformation experiments and Pore Pressure Oscillation measurements. Examine comparative analysis of two end-member rock types: the heterolithic siltstone-mudstone sequence of the Mercia Mudstone Group and the organic-rich claystones of the Ancholme Group. Understand the implications of permeability changes across elastic and inelastic stress domains for the long-term isolation of intermediate and high-level radioactive waste materials. Gain insights into the UK's geological disposal strategy and the critical role of rock mechanics in ensuring the safety of radioactive waste storage for up to one million years.
