Objectives • To show: • what the current possibilities are of geochemical modelling; • what our capabilities are through illustrative examples; • Which new developments we are working on • To discuss: • The role of geochemical modelling in the Belgian waste disposal programme • The possible use of geochemical modelling in the development of the new reference design
Introduction • Task group “geochemical modelling” • Initiated by P. Van Iseghem • Co-ordinated by L. Wang • Will be further developed as a co-ordination group for all geochemical modelling within the department • Overview • L. Wang: principles of geochemical modelling and some basic applications • S. Salah: application to uranium geochemistry • D. Sali: application to OPHELIE mock-up • D. Jacques: geochemistry coupled to transport • A. Dierckx: role of geochemical modelling in demonstrating feasibility and safety • Discussion on role of geochemical modelling in new reference design
Discussion: introduction Oxidation, heat, alkaline plume Carbonatation Corrosion Radiolysis effects
