Signature des contrats de construction pour les réacteurs nucléaires Cernavoda 3 and 4.
Cela va être deux réacteurs de type Candu (modérateur eau lourde ,combustible Uranium naturel sans enrichissement) , les premiers construits depuis 2007.
Key Cernavoda 3 and 4 engineering contract signed
Friday, 15 November 2024
The engineering, procurement and construction management contract for the completion of Romania's Cernavoda units 3 and 4 has been signed with the FCSA Joint Venture including Fluor, AtkinsRéalis, Ansaldo Nucleare and Sargent & Lundy Energie.
Romania's nuclear power plant operator Nuclearelectrica said that the estimated value of the engineering, procurement and construction management (EPCM) contract, which was signed at the COP29 climate conference, was about EUR3.2 billion (USD3.4 billion).
It will be structured in two phases. The first phase is the Limited Notice to Proceed, lasting between 24 to 30 months, followed by the Final Notice to Proceed phase lasting around 80-84 months. The latter phase is subject to commercial terms being agreed and a Final Investment Decision "being taken in line with the Support Agreement between the Romanian State" and Nuclearelectrica.
What is the project?
Cernavoda is the only nuclear power plant in Romania and consists of two 650 MWe Candu-6 reactors. Unit 1 went into commercial operation in 1996 and unit 2 in 2007. Operator Nuclearelectrica plans to extend the operating life of unit 1 to 60 years. Most of the work on the unfinished units 3 and 4 was done in the 1980s prior to the fall of the government of Nicolae Ceausescu in 1989. It was reported in 2021 that unit 3 was 52% complete and unit 4 30% complete.
In July this year the European Union issued a positive opinion on the technical and nuclear safety aspects of the construction of the two units, which have a scheduled operation date of 2030 for unit 3 and 2031 for unit 4. In October 2022, Romania said Canada and the USA were both offering to help with the financing of the construction of Cernavoda 3 and 4.
Romania's Energy Minister, Sebastian Burduja, said: "It is the most important project for the Romanian energy sector in recent decades. We have the strongest international partners with us to bring it to fruition by 2031-2032. Signing today's contract required a considerable effort, on all levels: diplomatic, financial, legal. The two new reactors will mean an additional installed power of over 1400 MW at Cernavoda, an increase in annual energy production in Romania by over 11 million MWh, for at least 30 years of operation, over 19,000 well-paid jobs and avoiding a minimum of 10 million tonnes of CO2 emissions each year. Once this investment is completed, in 7-8 years, Romania will provide over 30% of the national energy needs only through nuclear energy production. Today's historic step is also a symbolic one: Romania is able to carry forward strategic projects thought up 50 years ago and blocked by decades of hesitation, carelessness or lack of decision."

CANDU reactors
According to World Nuclear Association, the Canada-developed Candu reactors use heavy water (deuterium oxide) as a moderator and coolant, and are fuelled using natural uranium (as opposed to enriched uranium). The advantages of the Candu reactor are savings in fuel cost, because the uranium does not have to go through the enrichment process, and reduced reactor downtime from refuelling and maintenance. These savings are partially offset by the cost of producing heavy water.
The first commercial Candu reactors began operation in Canada in 1971 and there are now 27 Candu nuclear power reactors in seven countries as well as 18 'Candu derivative' reactors in India.
AtkinsRéalis said Cernavoda 3 and 4 would be first new Candu reactors built since 2007, and the company's President and CEO Ian L. Edwards, saying: "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 ... this also represents our first step in our expansion around the world as we aim to sell many more reactors."
Canada's government is providing export financing support of CAD3 billion (USD2.1 billion). The company's Candu life extension reactor support business is a CAD15 billion "total addressable market" with upcoming projects in China, Canada, Argentina, Romania, and South Korea that could include 19 Candu reactors over the next 10 years,
