Italy's Senate Approves Framework Law for Return to Nuclear Power After 40-Year Ban

On September 23, 2026, the Italian Senate voted 81 to 51, with seven abstentions, to pass a framework law that authorizes the government to reintroduce nuclear power to the national energy grid. The legislation does not immediately approve the construction of any specific reactors. Instead, it delegates authority to the executive branch to draft the comprehensive regulations required to manage a modern nuclear sector. This marks the first structural reversal of the country's nuclear ban since a 1987 referendum, held in the aftermath of the Chernobyl disaster, forced the closure of its four operational plants and halted all domestic atomic energy production.[2][3][4][5]

The newly approved framework gives the Environment and Energy Security Ministry, led by Gilberto Pichetto Fratin, a 12-month window to issue implementing decrees. These forthcoming rules will define the licensing procedures, safety standards, and territorial criteria for siting future facilities. They will also establish protocols for radioactive waste management, the decommissioning of legacy sites, and the creation of an independent nuclear safety authority to oversee the sector. The government has indicated that it expects to finalize these decrees by the end of 2026, accelerating the statutory timeline to begin soliciting project proposals.[1][2][3][4]

Rather than returning to the large-scale conventional reactors of the 20th century, the legislation specifically targets next-generation technologies. The regulatory focus is directed toward Small Modular Reactors (SMRs) and Advanced Modular Reactors (AMRs), which are designed to be manufactured in series and assembled on-site with lower upfront capital requirements. The government's National Integrated Energy and Climate Plan projects that these systems could eventually supply between 11 and 22 percent of Italy's electricity demand by 2050, operating as a baseload complement to intermittent renewable sources like wind and solar.[1][2][3]

The policy shift is driven by structural vulnerabilities in Italy's energy infrastructure, which were exposed during recent geopolitical supply shocks. Italy currently imports a significant portion of its electricity, including nuclear-generated power from neighboring France, while remaining heavily dependent on imported natural gas for domestic generation. Prime Minister Giorgia Meloni characterized the legislation as a mechanism to correct this imbalance, stating, "Today, Parliament definitively approved the nuclear law. After nearly 40 years, Italy once again has a regulatory framework to produce nuclear energy."[1][2][5]

Despite the parliamentary approval, the timeline for actual power generation remains extended. Ministry projections suggest the first next-generation reactors could become operational between 2033 and 2034, though commercial deployment of SMR technology is still in its early stages globally. Furthermore, the selection of specific sites for both reactors and waste storage facilities is expected to face substantial local resistance, a dynamic that has historically complicated infrastructure projects in the country and previously derailed a 2011 attempt to revive the nuclear sector.[2][3][4]

Opposition parties and environmental organizations have strongly criticized the framework, arguing that it diverts resources away from immediately available renewable energy technologies. Critics contend that relying on unproven SMR designs will prolong the country's dependence on fossil fuels in the near term, while failing to address the long-standing logistical challenges of permanent radioactive waste disposal. The legislation passed with the governing coalition's support, while the opposition voted against it, reflecting the continued political sensitivity of atomic energy in Italy.[2][3]

The Senate vote aligns Italy with a broader European reassessment of nuclear energy's role in achieving climate neutrality. As the European Union emphasizes technological neutrality in its decarbonization targets, countries across the bloc are re-evaluating their energy mixes to balance emissions reductions with industrial competitiveness. The European Commission has recently backed the development of small modular reactors, and nations such as Sweden and Belgium have revised their previous phase-out strategies to maintain or expand capacity.[2]

For Italy, the immediate next phase shifts from parliamentary debate to technical administration. The government must now draft the specific decrees that will determine how, and where, the new nuclear framework will operate. Only after these regulations are codified, and an independent safety authority is established, can the country move toward evaluating actual reactor designs and proposing physical sites for construction, testing the public's willingness to accept new atomic infrastructure.[1][2][3]
