CNSC Regulatory Oversight

nuclearsafety.gc.ca 4

• Ensure compliance with all licence conditions

• Permanent onsite inspectors

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• Work accident frequency and severity rates continue to be minimal• International obligations for peaceful use of nuclear energy continue to

be met
