Measurement of Diffusive Properties of Intact Rock (Mesures des Proprietes Diffusives de la Roche Intacte)
In the Postclosure Assessment of a Reference System for the Disposal of Canada's Nuclear Fuel Waste (Goodwin et al. 1994) the disposal vault is assumed to be surrounded by a zone of intact rock, referred to as the 'exclusion zone.' A sensitivity analysis of the relative effectiveness of the several engineered and natural barriers that contribute to the safety of the reference disposal system has shown that this zone of intact rock is the most effective of these barriers to the movement of radionuclides through the reference system. Peer review of the geosphere model used in the case study for the EIS (Environmental Impact Statement) of the Canadian Nuclear Fuel Waste Management Program has identified the need to quantify the properties of the intact rock surrounding the disposal vault that would control the transport of radionuclides by diffusion. This review describes and discusses the theoretical relationships that exist between Formation Factor, diffusivity, permeability, and porosity, and how these properties might be measured or inferred for in-situ rock under the conditions that apply to the intact rock surrounding a potential disposed vault.
