Extract

A model is proposed which describes the transport to and from a waste canister in a repository. The model includes flow and diffusion in the fractures in the bedrock as well as diffusion in the backfill. Calculations have been made on the inward transport of corrosive agents to a buried canister from the surrounding bedrock. The oxidants are transported from the flowing groundwater through the backfill to the surface of the canister, were they are assumed to react instantaneously with the canister material. The rock is modeled as a discrete fracture system. The fractures are assumed to be evenly spaced and the groundwater movement is described by potential flow. The model is three dimensional.
