The European Union is increasingly focusing on expanding its nuclear energy capacity to address energy security, industrial competitiveness, and the need for low-carbon power. Initial analyses emphasized that such expansion requires coordinated action to rebuild supply chains, improve project delivery, and establish stable financing frameworks to mitigate the risks of capital-intensive investments.

Building on these strategic needs, the European Commission has projected nuclear investments of approximately 241 billion euros by 2050. This policy shift aims to increase installed capacity from roughly 98 GW in 2025 to 109 GW by 2050, responding to rising consumption and geopolitical risks. This move follows previous assessments by European Commission President Ursula von der Leyen, who characterized the continent’s prior retreat from nuclear energy as a ‘strategic error’ much earlier.
