The European Investment Bank (EIB) has approved an EUR 800 million loan for the refurbishment of Unit 1 at Romania’s Cernavodă nuclear power plant, providing a major financing boost for one of the country’s largest strategic energy projects, state-owned nuclear producer Nuclearelectrica (BVB: SNN) announced on July 16, according to Romania Insider.
The total cost of the rehabilitation is around EUR 1.9 billion, and the preliminary phase of the project was already financed through a EUR 540 million loan signed in September 2025 with a banking syndicate led by JP Morgan SE.
The financing was approved by the EIB’s Board on July 15 and will require approval by Nuclearelectrica’s shareholders before the company can sign the loan agreement.
The project aims to extend the operating life of Unit 1 by another 30 years, allowing it to continue generating around 9% of Romania’s electricity supply between 2030 and 2060.
The EIB financing forms part of a broader funding strategy combining Nuclearelectrica’s own resources with loans and guarantees from international financial institutions, export credit agencies, and commercial banks.
Nuclearelectrica said the refurbishment project is currently in its second implementation phase, which includes obtaining permits, contracting engineering and construction services, procuring equipment, and securing the remaining financing. Civil construction works began in 2025 and have continued this year.
The third and final phase is scheduled for 2027-2030, when Unit 1 will be shut down to undergo extensive refurbishment, including replacement of the reactor pressure tubes. Commercial operation is expected to resume in 2030 following testing and commissioning.
From a stalled communist mega-project to the undisputed backbone of Romania’s modern energy security, the Cernavodă Nuclear Power Plant (CNE Cernavodă) represents one of the most successful industrial transitions in Eastern Europe. Between 1990 and 2026, the facility on the Danube-Black Sea Canal evolved from an abandoned, mismanaged construction site into a world-class nuclear hub, providing nearly 20% of the nation’s electricity and driving Romania’s shift toward a decarbonised economy.
Standing before the massive dome of Unit 1, the turbulent history of Romania’s nuclear ambitions feels distant. Today, in 2026, Cernavodă is widely recognized as a regional model of operational safety and efficiency. Yet, three and a half decades ago, the plant was a symbol of industrial stagnation, burdened by the collapse of the Ceaușescu regime and facing an uncertain future in a volatile, free-market economy.
The 1990s: Rescuing the Canadian Dream
The story of Cernavodă is unique in the former Eastern Bloc. Unlike its neighbors, who relied on Soviet VVER technology, Romania chose the Canadian CANDU (Canada Deuterium Uranium) system in the late 1970s. When the 1989 Revolution halted all major infrastructure, the site was in disarray, plagued by structural defects and a lack of qualified personnel.
The critical turning point came in 1991, when the Romanian government signed a management contract with a consortium formed by Atomic Energy of Canada Limited (AECL) and Ansaldo of Italy. This international intervention established strict Western safety protocols and modern project management standards. After years of financial constraints, Unit 1 was officially commissioned in April 1996, marking Romania’s entry into the global club of nuclear energy producers.
The 2000s and 2010s: Doubling Capacity and Operational Excellence
Following the successful integration of Unit 1, focus shifted toward the completion of Unit 2. State-owned operator Nuclearelectrica, established in 1998, navigated complex financing structures to resume work. Unit 2 went commercial in November 2007, instantly doubling the plant’s output and cementing its role as a vital economic pillar.
Throughout the 2010s, Cernavodă quietly built an impressive global reputation. According to data from the World Association of Nuclear Operators (WANO), the two Romanian reactors consistently ranked in the top five globally for capability factors (efficiency and reliability), outperforming hundreds of reactors worldwide due to rigorous maintenance and an unyielding culture of operational safety.
Decarbonisation and Geopolitical Realignment
In the current decade, the geopolitical landscape has fundamentally rewritten Romania’s energy priorities. The necessity of breaking away from regional fossil fuel dependencies transformed Cernavodă into a critical national security asset.
Furthermore, as the European Union intensified its green transition mandates, nuclear energy was recognized as a vital transition tool. Operating at zero carbon emissions, the plant has single-handedly prevented the emission of over 10 million tons of greenhouse gases annually, allowing Romania to meet climate targets while keeping domestic energy prices stable.
| Phase / Era | Operational Status | Strategic Objective |
| 1990 – 1996 | Unit 1 under reconstruction. | Restructuring management, adopting Western safety standards. |
| 1997 – 2007 | Unit 1 active; Unit 2 completed. | Doubling national nuclear capacity; ensuring regional grid stability. |
| 2008 – 2020 | Units 1 & 2 at peak efficiency. | Establishing global safety records; restructuring Nuclearelectrica. |
| 2021 – 2026 | Refurbishment of Unit 1; Units 3 & 4 development. | Securing decades of clean energy; introducing Small Modular Reactors (SMRs). |
Looking Ahead: The Unit 1 Refurbishment and Units 3 & 4
The evolution of Cernavodă is far from complete. The mid-2020s have brought the plant to its next grand challenge: the refurbishment of Unit 1. After 30 years of continuous service, the reactor is undergoing a massive chemical and structural overhaul to extend its operational lifespan by another three decades.
Concurrently, a strategic partnership backed by Western financing is actively moving forward with the construction of Units 3 and 4. This long-awaited expansion promises to double the plant’s current capacity, turning Romania into a major net exporter of clean energy in Southeastern Europe.
A Legacy built on Pragmatism
The 36-year journey of the Cernavodă Nuclear Power Plant is a masterclass in long-term industrial vision. By breaking away from Soviet technical dependency early on and maintaining an uncompromised commitment to Canadian technological standards, Romania built a highly resilient energy infrastructure.
As the country looks toward a future defined by clean technology and geopolitical volatility, Cernavodă remains a steadfast guardian of national independence—a testament to the fact that with proper international cooperation and strict technical discipline, the heavy industrial dreams of the past can successfully power the green economies of tomorrow.
