The uncertainties associated with the application of through-diffusion, the steady-state method: a case study of strontium diffusion
Original language description
In this study, the uncertainties associated with through-diffusion, the steady-state method used for determination of the pore diffusion coefficient (D-p), were analysed and evaluated. The diffusion of strontium through the sample of compacted bentonitewas studied to evaluate various sources of uncertainties and compare their contribution with uncertainty of D-p. Different diffusion experiment arrangements were used to test the effect of solution accessibility to the filter membranes. Three main general factors influencing the uncertainty of D-p at given conditions were identified: (a) the compacted sample preparation and its physical properties; (b) the properties of the diffusion cell; and (c) the strontium concentration analyses. Some of the identified sources can be treated as fixed with limited extent (e.g. the deformation of components of the diffusion cell), but some sources must be treated as variable with wide extent depending on the experimental conditions (e.g. the physical
