| Abstract | Fractures generally control ground water flow through rock masses. They, therefore, provide potential pathways for radionuclide transport from an underground nuclear waste disposal vault contained
within a rock formation to the biosphere. Fractures will also influence the long term stability of the mined structure which constitutes the immediate vault area. In regard to the latter, quantitative fracture/joint properties and joint models are
required if structural modelling of vault configurations are to be used to assess their stability and integrity for the containment of higher level nuclear waste. A method of quantitatively describing joint behaviour based on field data and simple
index testing is being studied within the Canadian Nuclear Fuel Waste Management Program (NFWMP) to permit the incorporation of such discontinuities in structural model studies. This report describes the procedure used to characterize small scale
core samples from the URL lease area in the Lac du Bonnet batholith, Manitoba. |
