This study presents and implements a screening methodology for assessing the potential postclosure radiological impact of a deep geological repository (DGR) for used nuclear fuel on non-human biota. This screening methodology is designed for hypothet

A screening ecological risk assessment was performed for regulatory compliance at two Ontario nuclear power generation station sites to establish design requirements for a contaminant-monitoring program and to address the need for non-contaminant str

Bentonite-based clays are proposed as a barrier to radionuclide migration in the geological disposal of used UO2 fuel. There is some evidence, however, that this buffer may be susceptible to cracking. Therefore, we have investigated the effect of cra

The oxidative dissolution of UO2 has been stimulated using thermodynamic reaction-path calculations. The extent of dissolution (as a function of the reaction coordinate) and the solid oxidation sequences are reported for various pH values, ligand (ca

An explicit mathematical formula has been derived, using thermodynamic principles, for the calculation of uranium dioxide solubilities as a function of temperature, pH, oxidation potential, and anion (carbonate, phosphate, sulfate, or chloride) conce

The dissolution of microcline by water is simulated using reaction path calculations. Alteration products of the microcline dissolution are reported for various temperature and pH conditions. The theoretical predictions of the microcline alteration p

Sensitivity surfaces have been developed to analyse the performance of engineered barriers of an underground nuclear fuel waste disposal vault. The major engineered barriers are the waste form, the containers and the buffer surrounding the containers

AbsractClay-based buffers are often proposed as engineered barriers for underground disposal vaults of used nuclear fuel. Thus, in the Canadian conceptual vault design, each used-fuel container is emplaced in a vertical borehole in rock and surrounde

A series of calculations of radionuclide release was performed with the AREST and SYVAC-Vault models (SVM) in order to assess concurrance. Specifically, the effects of precipitation and decay chain in-growth on the predicted release of nuclides from

The environmental assessment of the geological disposal of used nuclear fuel involves the assimilation of experimental results to produce an estimate of the potential impact of a disposal vault on man and the environment. In this paper we briefly out
