Environmental and safety assessment for nuclear waste disposal - the canadian approach

The Canadian concept for nuclear fuel waste disposal involves immobilization and emplacement in a crystalline rock formation in the Canadian Shield. The assessments are divided into two parts: the pre-closure assessment and the post-closure assessment. For the pre-closure phase the total impact of transportation, immobilization, emplacement and decommissioning is considered. The object of the post-closure studies is to predict how radioactive material might escape from a disposal vault and migrate through the geosphere and biosphere to cause radiation dose to man. Detailed computer programs are being developed and applied for hydrogeological and chemical modeling. A ''systems variability analysis'' code integrates the total system and samples data. The resulting output is a histogram of consequence (dose to man) versus probability, indicating the most probable consequence of the project, and other consequence estimates, together with their probability of occurrence.
