Reactive geochemical transport problems in nuclear waste analyses

This paper reviews the generic formulation of reactive geochemical transport problems that may be associated with the design or characterization of a nuclear waste repository. A summary of the relevant physical and chemical transport phenomena will be provided as a basis for developing suitable numerical models of these processes. Particular emphasis will be devoted to numerical and computational aspects of simulating the movement of several reactive chemical components within a porous medium using particle method. In addition, avenues for future theoretical and applied research will be discussed in light of the various uncertainties that presently exist in solving these problems. 14 refs.
