Safe and responsible, for today and tomorrow

Ontario’s electricity system is one of the cleanest in North America, and the world, thanks in large part to the role of nuclear power. Ontario’s nuclear reactors meet more than 50% of the province’s energy needs on any given day, so ensuring these plants can continue to operate safely and cost-effectively is a top priority. That’s where Nuclear Sustainability Services comes in. OPG’s Nuclear Sustainability Services division is a world-leader in safe and environmentally-sound nuclear material and radioactive waste management.

Lasting solutions: OPG remains focused on achieving permanent and safe solutions for nuclear materials, to protect people, the Great Lakes and the environment, for hundreds of thousands of years.

Peace of mind: Sound methods are used to reduce nuclear by-products from our facilities and secure its safe storage. By earning the confidence and trust of regulators and the public, we maintain our social licence to operate.
