The Canadian Nuclear Safety Commission (CNSC) has released for public review its draft study entitled Study of Consequences of a Hypothetical Severe Nuclear Accident and Effectiveness of Mitigation Measures.
The study is in response to the Commission’s request to assess the consequences and possible preventative mitigation of a hypothetical severe nuclear accident to address concerns raised during public hearings on the environmental assessment (EA) for the Darlington Nuclear Generating Station refurbishment project.
The study focuses on the assessment of health impacts of a hypothetical, unlikely scenario of a severe nuclear accident. Various scenarios were assessed, where radioactive releases happen without full consideration of multiple safety systems at Canadian nuclear power plants. Had all of the Fukushima Task Force enhancements been fully considered in the study, the likelihood of a severe accident would have been practically eliminated.
The study concludes that in the unlikely event of a radioactive release, there would be no detectable increased risk of cancer for most of the population, with the exception of a theoretical increase in childhood thyroid cancer risk. The result is not unexpected given the sensitivity of a child’s thyroid gland to radiation. The findings suggest that further consideration is needed in how children are considered as part of nuclear emergency planning.
The study is available for public comment until August 29, 2014. Copies may be requested and comments can be submitted through info@cnsc-ccsn.gc.ca.
The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
