COMSOL multiphysics, TOUGHREACT and Numerrin comparison in some modelling task of spent nuclear fuel disposal

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific

Abstract

The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics®, TOUGHREACT and Numerrin are used and compared in modelling the saturation, cation-exchange and mass transport in compacted bentonite. Model comparison was not a straightforward task due different approaches in the model setup. Therefore, we tried to write down all the equations and via parameterisation of those equations to create model descriptions near each other.
