CANDU Energy Inc.

CANDU Energy Inc. is a Canadian designer and supplier of nuclear reactor technology, specializing in the CANDU reactor design. It is the steward of the CANDU intellectual property and provides lifecycle services for existing reactors worldwide. The company operates as a wholly-owned subsidiary of the global engineering firm SNC-Lavalin, based in Mississauga, Ontario.

History

The company's origins are directly tied to the CANDU reactor development program initiated by the Crown corporation Atomic Energy of Canada Limited (AECL) in the 1950s. For decades, AECL was responsible for designing, marketing, and building CANDU reactors domestically and internationally, with major projects like the Bruce Nuclear Generating Station and Darlington Nuclear Generating Station. In 2011, the Government of Canada restructured AECL, selling its Reactor Division to SNC-Lavalin, which formed CANDU Energy Inc. to acquire the assets. This privatization followed a model similar to other national nuclear industry reorganizations, such as those undertaken by Électricité de France (EDF) and Westinghouse Electric Company. The transaction transferred the complete CANDU technology portfolio, including the advanced EC6 design, and ongoing contracts for projects like the refurbishment of Bruce Power units.

Operations and technology

CANDU Energy Inc. focuses on the design, engineering, and lifecycle support of heavy water reactors, utilizing natural uranium fuel and a pressure tube core design. Its flagship technology is the Enhanced CANDU 6 (EC6), an evolution of the proven CANDU 6 design that incorporates modern safety enhancements and digital control systems. The company provides comprehensive services for operating reactors, including refurbishment and life-extension projects, fuel supply, and decommissioning support. It also conducts research and development, often in collaboration with the Canadian Nuclear Safety Commission (CNSC) and laboratories like Canadian Nuclear Laboratories (CNL), on areas such as advanced fuel cycles and Small modular reactor (SMR) concepts derived from CANDU technology.

Major projects and reactors

The company's most significant ongoing projects are the multi-billion-dollar refurbishments of CANDU reactors in Canada, which are critical to extending the operational life of the country's nuclear fleet. This includes the massive program at Bruce Power's site in Ontario and the Darlington Nuclear Generating Station refurbishment led by Ontario Power Generation (OPG). Internationally, CANDU Energy Inc. has provided services for reactors it originally supplied, such as the Cernavodă Nuclear Power Plant in Romania, the Qinshan Nuclear Power Plant in China, and the Wolsong Nuclear Power Plant in South Korea. It was also involved in the construction of the Embalse Nuclear Power Station in Argentina.

Corporate structure and ownership

CANDU Energy Inc. is a legally distinct but fully integrated subsidiary of SNC-Lavalin, operating within its SNC-Lavalin Nuclear business unit. The president of CANDU Energy Inc. reports through the SNC-Lavalin executive leadership, including its Chief Executive Officer. While it maintains its specialized engineering teams and intellectual property, it leverages the broader resources of its parent company for large-scale project execution, financing, and global supply chain management. This structure is analogous to other reactor vendor subsidiaries like GE Hitachi Nuclear Energy or Framatome.

International presence and partnerships

The company maintains a global footprint through offices and joint ventures supporting its reactor fleet across several continents. Key international partnerships include long-term service agreements with Nuclearelectrica in Romania and cooperation with the China National Nuclear Corporation (CNNC). CANDU Energy Inc. actively pursues new build opportunities in markets considering large-scale nuclear, such as Saudi Arabia and Argentina, and engages in international forums like the International Atomic Energy Agency (IAEA). It also collaborates with other nuclear suppliers, having signed memoranda of understanding with entities like Rolls-Royce Holdings on Small modular reactor development and with Canadian Nuclear Laboratories on research initiatives.
