Tuesdays on the Trail wraps up

For more than two decades, the Tuesdays on the Trail program has provided family friendly activities for children ages 4 to 10 throughout July and August at OPG’s Pickering and Darlington nuclear sites. With summer winding down, OPG recently wrapped up another successful season of its Tuesdays on the Trail program.
With the generosity of our valuable community partners and student volunteers, this year’s lineup provided fun, free and educational activities at Alex Robertson Park in Pickering and along the Waterfront Trail in Courtice.
Community partners included Clarington Library Museums & Archives and Pickering Public Library, Scientists in School, Soper Creek Wildlife Rescue and Durham Community Health Care.
Thank you to our enthusiastic partners and to the families who attended; we hope to see you again next year.
Missed out on the fun? Visit opg.com/durham to see where staff from OPG’s nuclear stations will be next.

Pickering Refurbishment update
Pickering Nuclear is set to provide clean power for generations to come. With the support of the Province of Ontario, OPG has begun planning for another world-class refurbishment project. Once complete, Pickering Nuclear Units 5-8 will provide 30-plus years of carbon-free power for the province.
Refurbishing Pickering will:
- Secure more than 2,100 MW of clean, reliable nuclear power for Ontario.
- Power two million homes and businesses across Ontario, safely and reliably.
- Maintain and secure highly skilled jobs.
- Create significant economic impact of more than $19 billion over the refurbishment period in Durham Region and across the province.
None of this would be possible without the support of our neighbours, the residents in the Pickering and Durham communities. We will continue to put our communities first as we generate clean, reliable electricity for the people of Ontario. Learn more at opg.com.
Darlington New Nuclear Project

Minister of Energy visits Darlington and shares benefits of SMRs
In June, Stephen Lecce, the newly appointed Minister of Energy and Electrification, visited the Darlington New Nuclear Project (DNNP) site during his tour of OPG’s Darlington Nuclear Generating Station.
Lecce shared a few words about investing in nuclear power as part of the government’s larger plan to prepare for increased electricity demand in the 2030s and 2040s and build on Ontario’s and Clarington’s clean electricity advantage.
“Canada and the G7’s first small modular reactor is being built right here in this community,” said Lecce. “Just a year and a half later I am pleased to officially announce today that the first phase of site preparation work for the small modular reactor has been completed on time and on budget”.
Clarington’s new nuclear project achieves another milestone
The DNNP team has completed another major milestone, on time and on budget. After wrapping up the early phase of the site preparation licence work in February with completion of site grading and construction of temporary roads and laydown areas, work on main site preparation has begun. Work to be completed in 2024 includes construction work for site establishment activities, excavation for the first Small Modular Reactor (SMR) unit and clearing activities for additional future units.
In the spring, Canada’s nuclear regulator, the Canadian Nuclear Safety Commission (CNSC) concluded the DNNP environmental assessment is applicable and remains valid to OPG’s selected BWRX-300 technology. A second, two-part hearing to review OPG’s application for construction of the first of four SMRs is scheduled for October 2024 and January 2025.

Meet Durham Region’s newest nuclear leaders

Allan Grace was appointed to the Senior Vice President (SVP) position at the Darlington Nuclear Generating Station in January 2024. Allan has experience at both Pickering and Darlington Nuclear and also completed a secondment with the World Association of Nuclear Operators (WANO) in Atlanta, Georgia. Allan’s thoughtful and facilitative approach to leadership, his focus on safety and continuous improvement, and his past experience will be an asset as OPG looks to complete the refurbishment of the remaining Darlington units and transition the station to a four-unit operating site.
On a personal note, Allan and his wife Amie live in Clarington, ON with their two kids. They spend their spare time enjoying the kids’ extra-curriculars, including baseball and gymnastics, and as a family, they enjoy skiing and golf. Allan is a guitar enthusiast and holds an Engineering Physics/Applied Sciences degree from Queens University.

Pickering Nuclear welcomes Paul Seguin to the role of SVP. Paul is returning to Pickering where he began his career at OPG in 2000 in Station Engineering as a supervisor in the Control Room. He then held progressively more senior roles in Nuclear, Corporate and most recently as the SVP of Renewable Generation. Paul is excited to be back at Pickering to lead the station into the future as the team works towards the safe shutdown of Units 1 and 4 and the refurbishment of Units 5 to 8.
Paul is a graduate of the University of New Brunswick where he earned an Engineering degree. He lives in Toronto with his wife and their two kids. Paul’s time away from work is filled mostly with chauffeuring and cheerleading the kids’ many sports and social activities.
