Italian Senate: Approves Italy Nuclear Energy Return Legislation

• Italy's Senate approved legislation on September 23, 2026, paving the way for the country's return to nuclear energy after nearly four decades.
• The new law establishes a legal framework for next-generation nuclear technologies, with a focus on small modular reactors (SMRs).
• The government is authorized to draft crucial implementing decrees over the next 12 months, covering reactor licensing, safety standards, waste management, and site criteria.
• This move aims to bolster Italy's energy security, meet climate goals, and address rising electricity demand, according to Premier Giorgia Meloni's government.
• Significant challenges persist, including the lack of a permanent radioactive waste repository, potential local opposition, and economic concerns regarding high construction costs.

The forthcoming implementing decrees, expected within the next 12 months, will be crucial in defining the specific legal and operational landscape for Italy's re-engagement with nuclear power.

Italy's Senate recently delivered final approval to landmark legislation, signaling the nation's intent to re-embrace nuclear energy after a nearly four-decade hiatus. The measure, which had previously cleared the lower Chamber of Deputies, passed the upper house on Wednesday, September 23, 2026, with a vote of 81 in favor, 51 against, and seven abstentions. This significant parliamentary action paves the way for Italy nuclear energy return legislation, marking a critical step in Premier Giorgia Meloni’s broader strategy to bolster national energy security and achieve ambitious climate targets.

This Italian Senate nuclear power bill does not immediately authorize the construction of new reactors. Instead, it establishes a foundational legal framework specifically designed for next-generation nuclear technologies. While the actual development of new nuclear facilities remains years in the future, this legislative move provides the necessary regulatory bedrock upon which future projects can be proposed, thoroughly assessed, and ultimately approved.

A key provision within the newly approved legislation empowers the government to formulate and issue a series of implementing decrees over the subsequent 12 months. These forthcoming Italy reactor licensing decrees will be instrumental in defining the specific legal and operational landscape for the country's re-engagement with nuclear power. They are slated to cover crucial areas including the detailed process for reactor licensing, comprehensive safety standards, robust waste management protocols, and precise criteria for selecting future nuclear sites.

This focus on a modern regulatory framework underscores Italy's strategic shift towards advanced nuclear technologies, particularly small modular reactors (SMRs). Unlike the larger, conventional reactors that characterized Italy's initial nuclear program, which concluded after a 1987 referendum following the 1986 Chernobyl disaster, SMRs are touted by proponents as being safer, more flexible, and quicker to construct. This approach aims to address past public concerns, which also led to a second rejection of nuclear power in a referendum after Japan's Fukushima accident in 2011, while establishing a contemporary Italy SMRs regulatory framework.

The government, led by Premier Giorgia Meloni, frames this policy reversal as essential for addressing escalating electricity demand, meeting climate change commitments, and enhancing Italy's energy security in the wake of geopolitical events like Russia’s invasion of Ukraine. Minister of Environment and Energy Security, Gilberto Pichetto Fratin, emphasized that nuclear power, when integrated with renewable sources, represents a 'winning technology' capable of delivering 'extraordinary results' for the nation's energy independence. Historically, Italy has been heavily reliant on imported energy and is a major consumer of nuclear-generated electricity from neighboring countries since decommissioning its four operational reactors.

Anticipated substantial increases in electricity demand, driven by the electrification of homes, businesses, and transportation, alongside the expansion of data centers and other energy-intensive technologies, further underscore the rationale behind this move. This legislative action aligns Italy with a broader European trend, where countries like France and Poland are actively investing in or planning significant expansions of their nuclear programs to reduce carbon emissions and lessen dependence on imported fossil fuels. Public sentiment in Italy appears to have shifted, with a June 2026 survey by Only Numbers indicating approximately 55% support for next-generation nuclear plants, particularly strong among younger demographics who lack direct memory of the Chernobyl incident.

Despite the legislative progress, substantial obstacles remain before any new reactors can be built. A critical challenge involves the absence of a permanent national repository for radioactive waste, a legacy issue from Italy's previous nuclear program, with waste currently stored in temporary facilities across the country. The development of both future reactor projects and permanent waste storage sites is also expected to encounter opposition from local communities.

Furthermore, energy analysts have raised questions regarding the economic viability of nuclear power, citing high construction costs and the current lack of commercially proven SMR projects operating at scale within Europe. Industry estimates, for instance, place the cost of a single 300-mega (the source text ends here). These economic and logistical challenges highlight that while the legal framework is now in place, the path to a fully operational nuclear energy sector in Italy will require careful navigation and significant investment.

Lawyers advising energy companies, investors, or environmental groups operating or considering operations in Italy should closely monitor the government's upcoming implementing decrees over the next 12 months. These decrees will establish the specific legal framework for reactor licensing, safety standards, waste management, and site criteria, creating new compliance obligations and investment opportunities in the Italian nuclear sector.
