An approach to validation of solubility databases for performance assessment

This paper illustrates an approach which can be used to ''validate'' the solubility databases used for nuclear waste repository performance assessments. It is generally sufficient to demonstrate conservatism and, as such, validation may be undemanding in some cases. This is illustrated for the case of a concept feasibility study for HLW disposal in Switzerland. For the case where more realistic evaluation of repository performance is required, the requirements for validation may become more challenging. (orig.)
