This report describes the results of Chemval Stage 2, an international chemical model validation exercise involving the active participation of 14 organisations within EC countries, as well as Sweden, Switzerland and Finland. Four different sites were studied, representing a range of host rock types and proposed disposal facilities. Details are given of the methodology employed and results obtained for 19 test cases of varying complexity, devised to allow comparison between modelling results and experimental measurements. Recommendations are made for enhancement of models and thermodynamic databases employed, as well as for the collection of field/laboratory data geared to the needs of model validation. This report complements a previous one, EUR 12237 EN, devoted to the verification of speciation models.
