Nuclear energy is re-emerging as a strategic priority across South-East Europe, reflecting the region’s commitment to energy security, decarbonisation, and long-term price stability. Developments in April 2026 highlight renewed interest in nuclear investment, modernization, and fuel supply capabilities.
Across the SEE region, nuclear power accounts for approximately 21% of electricity generation, underscoring its importance as a reliable baseload energy source. Unlike intermittent renewables, nuclear facilities provide continuous output, supporting grid stability and reducing reliance on fossil fuels.
Romania remains at the forefront of nuclear development. Nuclearelectrica has launched a feasibility study to double its production of CANDU nuclear fuel, reinforcing the country’s ambition to strengthen domestic supply chains and enhance energy independence. This initiative aligns with broader European efforts to secure critical energy resources and reduce dependence on external suppliers.
In Serbia, nuclear power has returned to the national energy agenda. Authorities have announced plans to reach a decision on constructing the country’s first nuclear power plant by 2032, marking a potential turning point in the region’s energy landscape. The move reflects growing recognition of nuclear energy’s role in ensuring long-term supply stability and supporting decarbonisation goals.
Elsewhere in the region, Bulgaria and Romania continue to operate nuclear facilities that contribute significantly to regional electricity supply and cross-border exports. These plants play a vital role in stabilizing wholesale power prices and supporting European grid integration.
The renewed focus on nuclear energy comes amid rising geopolitical uncertainties and volatile fossil fuel markets. As Europe seeks to reduce dependence on imported fuels, nuclear power offers a low-carbon and domestically controlled alternative capable of delivering consistent output over decades.
Furthermore, nuclear energy is increasingly recognized as a complementary technology to renewable generation. By providing firm baseload capacity, nuclear plants enable greater integration of intermittent solar and wind resources without compromising grid reliability.
Investment in nuclear infrastructure also carries broader economic benefits, including job creation, technological development, and industrial growth. As governments evaluate long-term energy strategies, nuclear power is regaining prominence as a cornerstone of sustainable and secure electricity systems.
With feasibility studies underway, modernization projects advancing, and policy discussions intensifying, nuclear energy is poised to play a defining role in South-East Europe’s transition toward a resilient, low-carbon future.
