Preliminary analytical repository flow model

PDF Version Also Available for Download.

Description

This memo describes a preliminary model that predicts the flow of dissolved nuclear waste in an underground repository. The model is based on the flow of water that enters regions of the repository in which the waste is actually contained; it is expected to be an improvement over the current approach that assumes the waste flow is proportional to total flow of water along various pathways. The repository flow model is intended for implementation in the TASC WASTE computer code. The model treats the repository as a homogeneous two-dimensional slab contained in a geologic formation and penetrated by a shaft ... continued below

Description

This memo describes a preliminary model that predicts the flow of dissolved nuclear waste in an underground repository. The model is based on the flow of water that enters regions of the repository in which the waste is actually contained; it is expected to be an improvement over the current approach that assumes the waste flow is proportional to total flow of water along various pathways. The repository flow model is intended for implementation in the TASC WASTE computer code. The model treats the repository as a homogeneous two-dimensional slab contained in a geologic formation and penetrated by a shaft leading to an aquifer. Flow of water both perpendicular and along the central corridor is determined in order to compute the heads of the repository as a function of position. The heads are then used to estimate the fraction of waste that leaks to the formation and the fraction that travels up the shaft. The waste-splitting fractions are presented as closed form analytical expressions to facilitate rapid calculations. Numerical results for a typical geometry are also given.
