The presentation will discuss recently published results in the context of radioactive waste disposal in crystalline rocks. Fracture patterns are modelled as a function of mechanical and temperature changes, which are modelled in a coupled manner using a finite element solution of coupled partial differential equations. Fractures are modelled explicitly and results are compared against analytical and numerical data. Mechanical and thermomechanical results are discussed at the scale of a single deposition borehole, multiple deposition boreholes, and at the tunnel scale. Simulations discuss changes that occur during deposition, thermal load, and glaciation. These results are an example of the application of a coupled framework to an engineered case study; the talk will discuss many learnings being translated to porous media and other geological media studies. Future work will also be discussed.
