ATKINSREALIS SIGNS NEW EXECUTION CONTRACT FOR DARLINGTON SMALL MODULAR REACTOR PROJECT

Candu Energy Inc., an Atkinsrealis Group Inc. company, has been awarded a $450-million execution contract by Ontario Power Generation (OPG) for the first of four planned small modular reactor (SMR) units at the Darlington new nuclear project. The 300-megawatt BWRX-300 small modular reactor being delivered for OPG in the Durham region, east of Toronto, will supply enough power for 300,000 homes.

Atkinsrealis is providing OPG with expertise for the engineering of the SMR. This includes project management, licensing, engineering, design, procurement, construction support and commissioning, as well as digital delivery capabilities in both the nuclear island and balance of plant scopes for the project.

"As a world-class engineering services and nuclear organization, we are advocates for the role of SMRs in the energy mix to create stable, affordable and reliable power grids," said Ian L. Edwards, president and chief executive officer, Atkinsrealis. "Our involvement in the G7's [Group of Seven] first grid-scale SMR and Canada's first nuclear new build in roughly 30 years reaffirms our leading position in the global nuclear energy market, for both large and small reactor technologies. Our trusted relationship with OPG supporting hydro power assets and refurbishing Candu reactors at Darlington and Pickering will support this project's successful completion by 2030."

Atkinsrealis has been the architect-engineer on the Darlington new nuclear project alliance team since 2023. The company is working alongside GE Vernova Hitachi Nuclear Energy and Aecon Kiewit Nuclear Partners. The site preparation work undertaken under an earlier validation phase contract has been completed on time and on budget. The Canadian Nuclear Safety Commission has issued a licence to construct the SMR, and the Ontario government has also given its final approval for construction of the first of four planned units at the site.

"Atkinsrealis is a long-time trusted partner to OPG, including on the on-time, on-budget Darlington refurbishment project," said Nicolle Butcher, OPG president and CEO. "We will draw on our shared experience for similar success as we build the first small modular reactor in the G7 at the Darlington new nuclear project site."

"Ontario's power demand is expected to surge by 75 per cent by 2050, and we'll need all sources of cleaner power to meet the need, including large and small nuclear reactor technology," said Joe St. Julian, president, nuclear, Atkinsrealis. "Together with our alliance partners, we will ensure Canada continues to lead the G7 in advancing the use of SMR technology, as Atkinsrealis also continues to support international SMR projects in the U.K. [United Kingdom], U.S. [United States] and Poland."
