Cernavoda Nuclear Generating Station

The Cernavoda Unit 1 nuclear power plant—the first CANDU in Europe—provides about 10 per cent of Romania’s electricity requirements, saving millions of dollars in oil imports.

Romania realizes an annual savings equivalent to USD $100 million by using nuclear generated electricity instead of fossil fuel. And because a nuclear plant does not emit greenhouse gases that contribute to acid rain and global warming, Unit 1 has avoided the release of more than four million tonnes per year of carbon dioxide (CO2) that would have been produced had a fossil fuel plant been built instead.

The European Union’s second CANDU nuclear power plant, Unit 2, was officially placed in service on Friday, Oct. 5, 2007. Together with Unit 1, the CNE-Cernavoda Station is the largest power producer in the country.

Cernavoda 2 has had exceptional performance since in-service and has joined Cernavoda 1 as a world class performing nuclear plant. Together with Unit 2, nuclear power now accounts for about 20 per cent of Romania’s energy supply and significantly reduces its dependency on expensive energy resources from outside of Europe.

Canada’s CANDU technology has contributed to Romania’s healthy nuclear industry, and has proven to be an important economic asset for the country. CANDU technology also enhances energy self-sufficiency as both nuclear fuel and heavy water are produced by Romania.

Cernavoda Nuclear Power Plant Safety Systems Improvement

We engineered and installed new safety systems at the Cernavoda nuclear station to protect the environment and population as part of an industry-wide strategy to upgrade nuclear plant safety in the event of serious accidents or natural disasters like the one that occurred at Fukushima in Japan.

In 2011 and 2012, Societatea Nationala Nuclearelectrica awarded our Nuclear team two engineering, procurement and construction (EPC) contracts to install and improve the nuclear safety systems at the Cernavoda nuclear power plant. The plant provides roughly 20% of Romania’s electricity needs. Using nuclear power allows Romania to reduce its greenhouse gas emissions by over 10 million tonnes each year.

Engineering for the environment

Nuclear plant upgrades are both highly technical and extremely sensitive. At Cernavoda, we installed a filtered containment venting system, passive autocatalytic recombiners and a hydrogen monitoring system. The new venting systems will prevent excessive pressure buildup and ensure that Cernavoda continues to be a safe and clean source of power for communities.

We’re proud of our performance at Cernavoda. We installed the systems to the highest quality standards and completed the work ahead of schedule in 2013 and 2014. The systems are now rated among the best in the world.

Employing a local workforce

Local contractors and labourers carried out all the installation work at the Cernavoda nuclear power plant with no recorded health, safety or environment incidents. For us, outstanding health and safety is a top priority and an essential part of what we do.

 Sustainability achievements:
  • We completed the work ahead of schedule with no recorded health, safety or environment incidents.
  • The new safety systems are rated among the best in the world and were installed by local workers exclusively.
  • Nuclear power allows Romania to reduce its greenhouse gas emissions by over 10 million tonnes annually.
