Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste.
In this paper, an internationally organized benchmark exercise is presented, in which the comparison was carried out for a selection of key radionuclides.
The examples presented in this paper show that COMSOL Multiphysics can be a valuable complementary modeling tool, adequately representing most of the processes of importance in a radioactive waste repository, for varying and even extreme timescales.
