CNSC's Response to letter titled: Time for OPG to stop stonewalling on nuclear safety

We acknowledge receipt of your communication to President Velshi concerning the request from the Ontario Clean Air Alliance for safety information on the state of pressure tube systems at Ontario Power Generation.

Please be assured that the Commission operates as a transparent safety regulator. All evidence and materials considered by the Commission in its decision making are presented to it, in public proceedings and are publicly available, except where there are national security or other confidentiality requirements.

The Commission, in making its decisions on reactor restart, had before it the pressure-tube related safety information that it needed, and was satisfied that the information provided demonstrated that the authorized activity could be carried out safely. All submissions and documentation considered by the Commission in these matters may be accessed on the CNSC website free of charge.
