Belgium has officially reversed its nuclear phaseout policy and announced plans to build new nuclear reactors, citing growing energy demands, climate goals, and geopolitical uncertainty. The decision was confirmed this week by the Belgian federal government, marking a sharp departure from the country’s previous commitment to close all nuclear power plants by 2025.
Under the new policy, the operational life of existing nuclear reactors will be extended, while preparations begin for the construction of next-generation small modular reactors (SMRs). The government emphasized that nuclear energy will play a central role in ensuring energy security and achieving carbon neutrality by 2050.
Prime Minister Alexander De Croo stated that “nuclear power is a stable, low-carbon source of energy that cannot be ignored in the current geopolitical context.” He cited rising global energy prices, the war in Ukraine, and the need to reduce dependency on fossil fuel imports as key factors in the government’s shift.
Belgium currently operates seven nuclear reactors at two sites: Doel and Tihange. Two of the oldest reactors had been scheduled for decommissioning, but that plan will now be reconsidered following the decision. The government also plans to work closely with the EU and private sector partners on the financing and regulation of new reactor technology.
Environmental groups have expressed concern over the reversal, arguing that the focus should remain on renewable energy expansion. The government, however, has stressed that nuclear and renewables will complement each other in Belgium’s long-term energy strategy.
