Preclosure Safety Assessment for OPG's Deep Geological Repository for L&ILW

Abstract

The Preclosure Safety Assessment summarized in this paper evaluates the operational safety of OPG’s proposed Deep Geologic Repository facility, focusing on safety aspects associated with waste packages. The assessment addresses the safety of members of the public and workers, and includes both radiological and non-radiological (chemical) consequences. It involves an assessment of normal operations as well as hypothetical accident scenarios selected using a hazard identification process. Results indicate that credible hypothetical accidents would not produce exposures that exceed selected radiological and non-radiological dose criteria for members of the public or workers. Similarly, doses generated under normal operations would not exceed radiation dose limits.
