The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at 2.45 GHz for a standard wave guide and a concrete block. The temperature field is obtained with the heat equation and the microwave power dissipation as a source term. The displacements and stress fields are obtained by solving a thermo elastic model.
