Regulatory Oversight of Pickering and Darlington Nuclear Generating Stations
Canadian Nuclear Safety Commission
nuclearsafety.gc.ca e-Doc 5110000
• Regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment
• Implements Canada's international commitments on the peaceful use of nuclear energy
• Disseminates objective scientific, technical and regulatory information to the public
The Canadian Nuclear Safety Commission

We will never compromise safety
Licensees are responsible for the protection of health, safety, security, and the environment, and respecting Canada’s international commitments CNSC is responsible for regulating licensees, and assessing whether licensees are compliant with NSCA, regulations and international obligations
Regulatory Philosophy
October 2016
Durham Nuclear Health Committee , November 2016
• Five nuclear power plants with operating licences
• 19 reactor units operational • Gentilly-2 and Pickering, Units 2
and 3 remained in safe storage

Continuing to operate safely and responsibly
• No serious process failures at any nuclear power plant (NPP) • No radiation dose to public and workers above the regulatory limit • No radiological releases to environment above derived release limits • No NPP events above International Nuclear Event Scale level 0 • Accident frequency and severity rates continue to be minimal • International obligations for peaceful use of nuclear energy continue to
be met

Risk-informed and performance-based approach
• Compliance activities include surveillance and monitoring by onsite inspectors, announced and unannounced inspections and desktop expert reviews
• Safety performance determined by CNSC staff using results of activities planned through compliance verification program
• Inspectors track actions until closure and verify closures through follow-up inspections
