Mass transport in salt repositories: Transient diffusion into interbeds
- California Univ., Berkeley, CA (USA). Dept. of Nuclear Engineering
To estimate possible radioactive releases from a waste package to the near-field environment, we analyzed pressure-driven brine migration movement and release rates of low-solubility and readily soluble nuclides by diffusion. A possible pathway for radioactive release in salt repositories in interbeds and we have analyzed the steady-state transport of species through the interbeds in which there is ground-water flow. A more realistic situation is when there is no ground-water flow in the interbeds. Here we use some results previously obtained for transient diffusion of radioactive species from a waste cylinder intersecting a planar fracture in rock to the problem of diffusion from a waste cylinder intersecting an interbed in a salt repository. 5 refs., 8 figs., 3 tabs.
