The Canadian Nuclear Safety Commission (CNSC) said none of the operational events that occurred at Canadian NPPs from April 2013 to March 2016 – the reporting period for Canada’s seventh National Report for the Convention on Nuclear Safety – posed a significant threat to the health and safety of people or the environment. There were no serious process failures at any plant during the period. A serious process failure is defined as a failure that leads to systematic fuel failure or a significant release from a nuclear plant, or could lead to a systematic fuel failure or a significant release in the absence of action by any special safety system. The said licensees’ efforts to address operational events were effective in correcting any deficiencies and preventing their recurrence. During the period, the CNSC did not need to engage in formal enforcement actions. The CNSC said Canada has a strong overall safety record and it is confident in the safety of nuclear stations. Canada has 16 nuclear power reactors which generated about 16.6% of its electricity in 2015.
