Introduction to the Canadian Nuclear
Safety Commission (CNSC)
Regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment, and to implement Canada’s international commitments on the peaceful use of nuclear energy
Canada’s nuclear watchdog

Independent Commission Tribunal
• Quasi-judicial administrative tribunal
• Commission members are independent
• Commission hearings are public and Webcast
• Decisions can only be reviewed by Federal Court
Transparent, science-based decision making

Regulatory Oversight
CNSC Regulatory Framework
Canadian Nuclear Safety Commission 2012 INPRO Dialogue Forum - 8
CNSC’s Overall Regulatory Approach
• CNSC sets high-level safety objectives
• CNSC sets performance objectives related to
− Capacity of systems to control reactivity
− Capacity of systems to shutdown reactor in a timely manner
− Reliability of the control and shutdown functions
• CNSC has no set requirements for reactivity feedback, positive or negative but magnitude is important
• Requirements meet international best practice including IAEA
• Peer reviewed and internationally accepted (CNS)
Robust regulatory approach, while permitting
flexibility in how to achieve safety objectives
