Our commitment to safety

A commitment to safety in action

Nuclear failsafes

Our nuclear stations are fitted with rapid shutdown systems that stop a chain reaction within seconds. Independent from the rest of the plant, each key safety component has three backups. The station containment systems are also designed to lock harmful radiation within the facility. Ontario’s CANDU reactors have considerable redundancy in back-up power supplies, including standby generators, emergency power generators, and auxiliary generators with varying degrees of seismic resiliency.

Emergency preparedness

In the unlikely event of an accident at one of our nuclear facilities, our responsibility is to make sure it is controlled, and any radiation releases are minimized. We maintain an emergency plan and work with the Province of Ontario, Durham Region, and the City of Toronto to ensure emergency responses to many scenarios are tested on a regular basis.

Public water safety

OPG staff work closely with partners in site communities to promote public safety around dams and hydroelectric stations. Our province wide “Stay Clear, Stay Safe” water safety campaigns illustrate the dangers of water near hydro dams and stations. OPG’s properties and facilities are clearly marked with warning signs, and barriers are in place to prevent access. In addition to these safety measures, video surveillance has been installed at some of our hydroelectric facilities for public safety purposes. For further information about OPG’s collection, use, and disclosure of personal information, please contact our Freedom of Information Coordinator.
