Abstract

In support of confirming Probabilistic Safety Assessment (PSA) scope at Point Lepreau Nuclear Generating Station, a comprehensive evaluation and screening of external hazards was performed based on a list of all potential external hazards compiled from a variety of sources. Screening criteria were established; events were evaluated against the screening criteria to determine if the events were risk significant; and, for those events not screened out, bounding analysis was performed to determine if further detailed analysis for the event is warranted via PSA. Potential hazard combinations following Canadian industry practice has also been incorporated and all combinations have been screened out. The assessments have shown that there are no external hazards requiring further detailed analysis other than seismic hazards for which a seismic PSA is being performed
