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
