In nuclear power plants, the water contained in different circuits is purified by passing through ion exchange resins. Prediction of the performance of these resins is an important help to the plant operators. To this end, the method of reactive transport modeling are well suited and is the basis of the OPTIPUR code that was designed to model the resins. The work presented in this manuscript covers three main aspects. The first one is the integration of a limitation to mass transfer in a ion exchange deep bed, taking into account a specific mobility for each chemical species, in the context of separated calculations for chemistry and transport. This model was shown to reproduce experimental data, without adjustable parameters. The second pa...
