3 Potential applications Significant experimental and numerical research on coupled THCM behaviour for soil and concrete applications. Nuclear waste repository Ground freezing Petroleum Geotechnical in general Current interest Deep disposal Near-Surface disposal 3
4 Potential applications THCM: In situ Processes in deep disposal repository in Boom Clay CHM: Impact of bitumen waste on Boom clay THM Design phase - Half scale test - Supercontainer H, CM, CH: Near surface disposal concept based on concrete as predominant material 4

17 Benchmark 3 Reactive transport (COMSOL-MATLAB) c l t i. D c c R i i iv l i Phreeqc coupling via MATLAB use sequential noniterative approach (other approaches also tried, no difference for the specific problems chosen) 17
18 Ion exchange, Mineral dissolution verifications Inlet Outlet CaCl 2 Na-K-NO3 2- +Exchanger Advection-diffusion Comparison made with open source code HP1, developed at SCK-CEN 5 Low ph boundary Ca 20 mm, ph 12.5 Diffusion only Initial portlandite =4 mm Portlandite (mm) COMSOL PHREEQC Time (hrs.) Input data: Patel, R.A., Perko, J., Jacques, D., De Schutter, G., Breugel, K. V., Ye, G., A versatile pore-scale multicomponent reactive transport approach based on Lattice Boltzmann Method: Application to cementitious systems. Jour. Phy. and Chem. of the Earth (submitted) Portlandite dissolution Note: More complex chemistry successfully demonstrated 18 in a forthcoming journal publication
19 Conclusions and perspectives Model implementation and benchmark results highly encouraging. Further work ongoing in terms of chemo-mechanical coupling, plus more and more verifications/validations. Computational constraints especially iterating between COMSOL- MATLAB. Perhaps COMSOL can consider this in future versions. COMSOL: easy to implement and serves as a powerful research tool. 19
