Assessment of the Long-Term Risks of Inadvertent Human Intrusion into a ProposedCanadian Nuclear Fuel Waste Disposal Vault in Deep Plutonic Rock. Revision 1 (Evaluation des Risques a Long Terme...)

摘要

This report describes the methodology developed to assess the long-term risk frominadvertent human intrusion into such a facility, and the results of its application to the proposed facility. Four intrusion scenarios were analysed, all initiated by a drilling operation. These scenarios are exposure of a member of the drilling crew, of a technologist conducting a core examination, of a construction worker and of a resident. The consequence of each scenario was estimated using standard computer codes for environmental pathways analysis and radiation dosimetry.
