Major industry milestone for AtkinsRéalis with contract win to build two new multi-billion dollar CANDU nuclear reactors

• The first new CANDU reactors to be built since 2007
• Signals a new era in the construction of large reactors in support of the nuclear super cycle
• Represents the first step in AtkinsRéalis' strategy to sell more new CANDU reactors globally
• Financing of the new reactors to be supported by $3 billion from the Government of Canada and additional capital from other governments
• Enables the expansion of the production of lifesaving medical isotopes

MONTREAL , Nov. 15, 2024 /CNW/ - Candu Energy Inc., an AtkinsRéalis company [AtkinsRéalis Group Inc.] (TSX: ATRL), in a joint venture with Fluor Corporation, Ansaldo Nucleare and Sargent & Lundy, has been awarded a contract from EnergoNuclear S.A., to build two new CANDU ^® reactors at the Cernavoda Nuclear Generating Station in Romania ; the first in the world since 2007. These units will allow Romania to almost double the production of clean, reliable and affordable electricity.

"This is a game changing contract for AtkinsRéalis and Romania . As the sole commercial licensee of world-renowned CANDU technology, we are uniquely positioned to contribute to the vast expansion of the world's clean power," commented Ian L. Edwards , President and Chief Executive Officer, AtkinsRéalis. "CANDU technology is at the forefront of relevant, up to date and differentiated nuclear technologies in the world. We are honoured to help power Romania well into the end of the 21st century with these brand new CANDU reactors. I would like to thank the Government of Canada who helped make this contract possible through export financing support of $3 billion . This also represents our first step in our expansion around the world as we aim to sell many more reactors."

" Canada is proud to stand at the forefront of the global clean energy transition, with CANDU nuclear technology as a pillar of innovation and reliability," said Mary Ng , Minister of Export, Trade & Economic Development for Canada . "This collaboration in Romania highlights Canada's leadership in nuclear energy, providing clean, resilient solutions that enhance energy security, reduce emissions, and support economic growth. Through this partnership, we're not only creating good, high-paying jobs and advancing sustainable growth, but we're also reinforcing Canada's commitment to a low-carbon future and strengthening resilient supply chains for a better world."

CANDU New Builds at Cernavoda

As the original equipment manufacturer of the Canadian-owned CANDU technology, AtkinsRéalis will provide design, engineering, and procurement services, as well as support to EnergoNuclear to meet European Union directives around the project, and interfacing with Romania's nuclear power regulator, National Commission for Nuclear Activities Control (CNCAN). These two new units for Romania are the first CANDU new builds in the world since Romania's Unit 2 nuclear reactor came online in 2007; they signal a new era in the construction of large reactors in support of the nuclear super cycle in response to the increasing global demand for energy.

EnergoNuclear is the Romanian entity responsible for construction, commissioning and operation of Units 3 & 4— using CANDU technology—at Cernavoda. The initial first phase of the mandate is worth $224 million . After completion of the initial phase, EnergoNuclear has the option to issue a full notice to proceed with the services necessary to complete Units 3 and 4, subject to the agreement of commercial terms.

"28 years of excellent operation of Cernavoda NPP Units 1 and 2, outstanding safety record, 230 million MWh into the grid and 215 million tons of CO2 avoided are the merits of CANDU technology and human expertise. We are keen on extending the historic cooperation with AtkinsRéalis, for the deployment of Units 3 and 4 and provide Romania with long-term safe, reliable and clean energy. Nuclear energy is a major part of the global effort for deep decarbonization and by extending CANDU nuclear capacities in Romania , we aim to prove that energy security, energy availability and energy resilience together with 66% of Romania's clean energy can efficiently be provided by a single energy source, nuclear, based on years of experience, strategic partnerships and robust technology," stated Cosmin Ghita , Nuclearelectrica Chief Executive Officer.

With Candu Energy and most of its staff based in Mississauga, Ontario's Minister of Energy and Electrification Stephen Lecce commented: " Ontario is proud to lead in nuclear energy, providing clean, reliable, and affordable power while positioning our province as a global leader in this critical sector. By exporting our nuclear expertise worldwide, we're showcasing Ontario's innovation and commitment to an affordable energy future. While we refurbish and expand nuclear fleets around the world, we are bringing jobs and investment back home for Ontario families and workers."

CANDU Technology in Romania : A Canadian Success Story

The Cernavoda site houses Romania's only nuclear power plant. Providing about 20% of the country's power ¹ , currently consisting of two CANDU 6 reactors (Units 1 and 2) on a site layout that was originally constructed for five. Each reactor produces around 720 MW of clean power, 24/7 for the grid. The Unit 2 CANDU reactor at Cernavoda holds the world record for highest capacity factor (composed of reliability and up-time) of any nuclear reactor globally. ²Romania is also preparing for the life extension of Unit 1; a project in which AtkinsRéalis holds a central role.

Romania has avoided the release of over 215 million tons of CO2 since the two existing CANDU units came online in 1996 and 2007, respectively. ³  The long-term operation of CANDU technology is central to helping Romania reach its goal of energy stability and decarbonization; including phasing out coal-fired power. ⁴

This project will also unlock Romania's potential to become a regional hub for energy security and clean electricity in Eastern Europe with the support of Canadian technology. The unique ability of CANDU reactors to utilize unenriched uranium offers an additional layer of energy security, via bypassing foreign fuel enrichment.

"Canadian CANDU technology has served Romania well and is the right choice for the next 60 years," said Joe St. Julian , President, Nuclear, AtkinsRéalis. "The last seven CANDU reactors built around the world, and the ongoing life extension of 10 CANDU reactors in Ontario , have been conducted on time and on budget. We will employ our unmatched nuclear power know-how as the steward of this technology, to ensure a similarly successful outcome for the build of these two new units in Romania ."

CANDU technology also co-produces medical grade life-saving isotopes to sterilize medical equipment worldwide, and for use in both detecting and fighting cancer. CANDU reactors in Canada produce 50% of the world's supply of the Cobalt-60 isotope. ⁵

BACKGROUND

CANDU Reactors: A Jobs Powerhouse for Canada

With the CANDU supply chain being 85% Canadian, new builds of CANDU reactors at home and overseas create significant opportunities across the Canadian nuclear supply chain of 89,000 roles. ⁶

Having already grown significantly in the last two years to over 2,000 people, AtkinsRéalis' Canada Nuclear business will be further expanding for this project, hiring new roles at its Ontario offices. These include highly skilled and well-paying engineering, skilled trades, and manufacturing jobs, which sustain Canada's global status as a Tier-1 nuclear nation.

Due to the unmatched domestic jobs creation potential of CANDU technology among large nuclear reactor designs, AtkinsRéalis launched the Canadians for CANDU campaign in 2024. It calls on the Canadian federal and provincial governments to support the deployment of CANDU reactors at home and overseas, as the only made-in- Canada nuclear technology in existence. 19 organizations have signalled their support to the campaign, representing over 60,000 unionized workers. ⁷
