  • New Brunswick Energy and Utilities Board (EUB)

Nuclear Safety Oversight

NB Power Nuclear’s nuclear safety regulator is the Canadian Nuclear Safety Commission (CNSC). The CNSC is responsible under the Nuclear Safety and Control Act for regulating all nuclear facilities and nuclear-related activities in Canada. The CNSC grants the stations’ operating licences, which set out the regulations and requirements the station must operate under.

Oversight of NB Power Nuclear Activities

The CNSC has a presence at each nuclear station in Canada. CNSC staff members have continuous access to inspect our stations and review our activities. CNSC staff report our activities to the CNSC Commission Tribunal, an appointed body of individuals who provide further oversight on nuclear activities.

In addition to NB Power Nuclear’s own rigorous internal safety reporting and review process, NB Power Nuclear is also required to formally notify the CNSC of activities which meet a defined criteria. Event Reports are provided to CNSC staff when an activity meets the thresholds set out by the CNSC’s regulations. These reports, numbering approximately 50 in a year, represent a very small fraction of the activities undertaken in a nuclear station every year but each is given scrutiny to understand the cause of the problem, the corrective action and resolution. Upon review of CNSC staff, each year, typically a handful of these Event Reports may be identified as having enough significance to warrant further review by the CNSC Commission Tribunal at one of their regularly-held public meetings. The cause of the problem and remedial actions and resolution of the event will be discussed in a public forum with this further level of oversight and accountability at these meetings.
