Italy's 2026 Nuclear Framework: Understanding the Long-Term Energy Strategy for Residents

Italy's Ministry of Environment and Energy Security has outlined a strategy that positions nuclear power as a necessary partner to renewables—not a replacement—in the country's push toward decarbonization. Speaking at the second annual "Energy Transition and the Nuclear Industry" conference hosted by Il Sole 24 Ore, Minister Gilberto Pichetto Fratin argued that failing to integrate nuclear capacity would be "a choice of backwardness" for Italy.

Why This Matters:

• Legislative deadline: Parliament is expected to pass a nuclear framework law by summer 2026, with implementation decrees finalized by year-end.

• Long-term target: Italy aims for 8-16 GW of nuclear capacity by 2050, covering 11-22% of electricity demand.

• No immediate construction: New reactors won't be built during the current legislative term; the focus is creating legal infrastructure for future deployment.

• Waste challenge: A temporary radioactive waste storage site must be identified before the current government's mandate expires.

Nuclear as Complement, Not Substitute

Pichetto Fratin was explicit: nuclear energy is meant to displace fossil fuel-based thermal generation, not crowd out wind, solar, or other renewables. "Green energy must be integrated with nuclear," he said, adding that Italy remains on track with its renewable deployment roadmap—reaching 1.4 GW of new capacity by December 31, 2025, slightly above the national plan's milestone.

The minister framed the debate in geopolitical terms, noting that Europe is pivoting toward nuclear precisely because over-reliance on external suppliers—many in politically unstable regions—has exposed the continent to supply shocks and price volatility. For Italy, a country that imports roughly 80% of its energy, diversifying the generation mix is not just an environmental imperative but a matter of national security.

What This Means for Residents

For households and businesses in Italy, the nuclear strategy carries both promises and uncertainties. On one hand, a more diversified energy portfolio could stabilize electricity prices and reduce exposure to fossil fuel market swings. On the other, the timeline is distant: the first operational reactor is unlikely before 2035, with meaningful grid contributions only arriving in the 2040s.

In practical terms, Italians should not expect nuclear power to lower their bills or change the energy landscape in the next decade. The immediate focus remains on renewable expansion and grid modernization. The government has allocated €60 M over 2027-2029 for nuclear-related investments and another €7.5 M for public communication campaigns—figures dwarfed by the capital flowing into solar and wind projects.

The nuclear plan also hinges on Small Modular Reactors (SMRs), a technology still in the prototype stage in Western countries. Italy's state energy agency, ENEA, plans to build a non-nuclear demonstrator facility at Brasimone by late 2026, simulating the thermal, fluid dynamics, and control systems of an operational SMR. This is a research milestone, not a power plant.

The Road to 2050: Technology and Timeline

Italy's nuclear ambitions are anchored in the 2050 National Integrated Energy and Climate Plan (PNIEC), which forecasts nuclear contributing between 11% and 22% of total electricity generation—equivalent to 8-16 GW of installed capacity. The government is betting on third-generation advanced SMRs in the near to medium term, while monitoring fourth-generation technologies like lead-cooled fast reactors.

Seventy Italian firms are part of the European Industrial Alliance on SMRs, positioning domestic industry to capture a slice of the supply chain if the technology matures. The European Commission is expected to release its own SMR strategy in the first half of 2026, potentially unlocking further EU funding streams.

However, expert criticism is mounting. Giuseppe Onufrio, former director of Greenpeace Italy, and energy analyst Gianni Silvestrini have called the nuclear option "economically inconsistent" and "extremely costly" compared to renewables. A study cited by Il Fatto Quotidiano in early 2026 found that electricity from SMRs could cost 50% more than power from conventional reactors. In the United States, cost estimates for the NuScale SMR project range from $250 to $354 per megawatt-hour—figures that dwarf the falling costs of solar and wind.

The Bank of Italy has also issued caution, warning of potential budget overruns, while the Network 100% Renewables coalition pointed out that SMR costs in China and Russia have tripled during development.

Legislative Framework and Governance

The draft nuclear law currently before Parliament is designed to establish a comprehensive regulatory framework covering plant licensing, safety oversight, waste management, and decommissioning. If enacted by summer 2026 as planned, the law will empower the government to issue a series of legislative decrees by December 2026, setting the rules for civilian nuclear production in Italy for the first time since the sector was shuttered following the 1987 and 2011 referendums.

Key provisions include:

• Strengthening the national nuclear safety authority to meet international standards.

• Defining the governance model for site selection, construction, and operation.

• Establishing waste management protocols, including interim storage and long-term geological disposal.

• Clarifying liability and insurance requirements for operators.

Italy joined the European Nuclear Alliance in June 2025 and is participating in Important Projects of Common European Interest (IPCEI) focused on advanced nuclear technologies. This aligns Rome with a coalition that includes France, Poland, Croatia, Estonia, and Belgium—all pursuing nuclear as part of their decarbonization strategies.

Waste, Costs, and Social Acceptance

One unresolved issue is radioactive waste disposal. Italy still lacks a permanent repository, and the government has pledged to identify a site for temporary storage before the end of the current legislature. Complicating matters, studies suggest that SMRs may generate 2 to 30 times more radioactive waste per unit of energy than traditional reactors, depending on the design.

Social acceptance remains fragile. Italians have voted twice—in 1987 and 2011—to exit nuclear power, and the NIMBY (Not In My Backyard) syndrome is expected to resurface once specific sites are proposed. The government's €7.5 M communication budget is aimed at shifting public opinion, but polls suggest skepticism remains high.

From a cost perspective, critics argue that nuclear power—whether large-scale or modular—survives only through substantial state subsidies. In contrast, renewable energy costs continue to fall sharply: in 2025, wind and solar together supplied 30% of EU electricity, surpassing fossil fuels (29%) for the first time. Italy's renewable share reached 48% of total energy consumption in 2025, driven largely by solar photovoltaic expansion.

European Context: A Divided Continent

Across the EU, the approach to nuclear is anything but uniform. While the European Commission's Clean Industrial Deal (February 2025) explicitly supports nuclear alongside renewables, member states remain divided. Germany, Portugal, and Austria are pursuing 100% renewable strategies, while France—Europe's nuclear heavyweight—continues to rely on fission for roughly 70% of its electricity.

The EU's broader goal is for over 90% of electricity to come from decarbonized sources by 2040, with nuclear providing stable baseload power to balance the intermittency of wind and solar. The bloc has earmarked a temporary €200 M through InvestEU until 2028 to support SMR, advanced modular reactor (AMR), and microreactor deployment.

Nuclear currently accounts for about 28% of EU power generation (Eurostat 2024 data), with installed capacity expected to rise from 98 GW in 2024 to roughly 109 GW by 2050. Yet this growth is modest compared to the explosive expansion of renewables, which are forecast to add nearly 350 GW of solar alone by 2030.

Pichetto Fratin's Vision: Fusion on the Horizon

The minister closed his remarks with a nod to the future: nuclear fusion. "My dream is fusion," he said, adding with a touch of humor that he hopes to attend the inauguration of a commercial fusion plant—"even if at 95 years old, that will be tough."

Fusion, the process that powers the sun, produces no long-lived radioactive waste and uses abundant fuel. But commercial fusion remains decades away, with most experts forecasting the 2050s or later for the first grid-connected plants.

For now, Italy's nuclear strategy is firmly rooted in fission-based SMRs, a legislative sprint to build the legal groundwork, and a long-term bet that the technology will mature in time to meet mid-century climate targets. Whether this gamble pays off—or whether cheaper, faster-deploying renewables render it obsolete—remains an open question.
