Bruce Power Environmental Risk Assessment
International Safety Research (ISR) was contracted to conduct the radiological component of a preliminary quantitative risk assessment for the Bruce Nuclear Generating Station. This assessment identified any potential human health and environmental risks as a result of historical and ongoing operations at the facility and if these risks need to be addressed. Any risks associated with radiation dose to humans were calculated following the CSA N288.1 Standard using the IMPACTTM modelling software. Toxicity assessments for various airborne and waterborne release pathways were considered for a number of radionuclides. ISR defined criteria to categorize the level of risk to humans; these categories correlated to a recommended environmental monitoring plan. ISR also performed a radiological exposure assessment for non-human organisms to determine the radiation dose at the exposure location.
