Defining small-scale fluid migration in a granite aquifer and evaluating barriers for fracture grouting
2011
Abstrakt
This paper outlines the results of a four year project that has examined small-scale fluid migration within a fractured granite aquifer. The project provides important information relevant to radioactive waste disposal.
The features of the rock environment have been intensively studied under both laboratory and field conditions. From these data, a highly accurate three dimensional model of the site was constructed.
Barriers that can be used for fracture grouting were applied and additional tracer tests were subsequently undertaken. A descriptive model of the site was used to predict the results of the tracer tests.
The measured and predicted field results have been compared. From this, the level of model reliability is discussed.
