Highlights of 2023 year in review with Bruce Power

There is no doubt that 2023 was a year of progress for Bruce Power with the culmination of projects that have been years in the making, and the possibilities of new ones on the horizon, along with ever-expanding medical isotope production helping in the global fight against cancer.

“As we look back on 2023, there’s so much to celebrate for those who work with Bruce Power and in the nuclear industry,” said Mike Rencheck, Bruce Power’s President and CEO. “Our people, our communities, and our partners have a lot to be proud of as we continue to support our communities and provide clean, reliable electricity to the province and cancer-fighting medical isotopes to the global health-care community.”

In 2023, Bruce Power brought its renewed Unit 6 back online safely, with high quality, ahead of schedule and on budget after a successful Major Component (MCR) outage to provide clean and reliable power for the people of Ontario for decades to come. The company also began its Unit 3 MCR outage, leveraging lessons learned and the strong performance in Unit 6. Unit 7 set its continuous operation record of over 520 days and continues the run into the new year.

The company continued to use its reactors not only as a source of clean energy, but also as a strong provider of much-needed medical isotopes for the world health-care community. Bruce Power harvested its largest historical shipment of cobalt-60, used to sterilize billions of single-use medical devices and for targeted cancer treatment, and also was able to increase its capacity to produce cancer-fighting lutetium-177 through innovations to its Isotope Production System in 2023.

The Ontario Government announced big news in the summer when it included Bruce Power in its Powering Ontario Growth Plan to study the feasibility of adding new nuclear to the already established site.
