How is Italy planning to restart nuclear power after nearly four decades?

Italian Prime Minister Giorgia Meloni has confirmed her government is preparing to launch a comprehensive nuclear framework within months, marking Italy's first concrete steps toward reintroducing nuclear energy since the country's 1987 referendum banned nuclear power following Chernobyl. The announcement signals a potential end to Italy's 37-year nuclear moratorium and could position the Mediterranean nation as Europe's next major nuclear growth market.

Italy currently relies on energy imports for approximately 77% of its electricity needs, creating both energy security vulnerabilities and some of Europe's highest electricity prices at €150-200/MWh during peak periods. The country shuttered its last nuclear plant in 1990 and has since depended heavily on natural gas imports, particularly from Russia until 2022. Meloni's framework announcement comes as Italy faces mounting pressure to decarbonize while maintaining industrial competitiveness and energy independence.

The timing aligns with broader European Union support for nuclear energy as a clean baseload power source, with the EU Parliament recently classifying nuclear as "green" under taxonomy regulations. Italy's nuclear return could trigger significant market opportunities for both established reactor vendors and emerging SMR developers targeting the European market.

What technologies could Italy consider for nuclear restart?

Italy's nuclear framework will likely focus on advanced reactor technologies rather than traditional large-scale plants, given public acceptance challenges and faster deployment timelines. Small modular reactors represent the most probable pathway, with several European-based companies already positioning for Italian market entry.

Newcleo, the London-based startup developing lead-cooled fast reactors, has specifically targeted Italy as a priority market. The company raised €300 million in 2023 and plans to deploy 30 MWe modules beginning in the early 2030s. Newcleo's Italian connections through founder Stefano Buono could provide advantages in navigating local regulatory and political landscapes.

European SMR competitors include Rolls-Royce SMR Ltd with its 470 MWe pressurized water reactor design, though the larger capacity might face greater public resistance. French state-backed Nuward, a 340 MWe SMR joint venture between EDF and Framatome, represents another potential option given France-Italy energy cooperation agreements.

Advanced reactor technologies using TRISO fuel or molten salt coolants could also attract Italian interest, particularly if positioned as inherently safe designs requiring smaller emergency planning zones. However, these technologies face longer regulatory timelines and limited commercial demonstration.

How significant is Italy's energy import dependency?

Italy imports roughly 320 TWh annually, representing one of Europe's largest energy import bills at approximately €50-60 billion per year. Natural gas accounts for 42% of electricity generation, with imports from Algeria, Azerbaijan, and LNG terminals replacing Russian supplies post-2022.

This import dependency creates both economic and strategic vulnerabilities. Italian electricity prices averaged 40% higher than EU averages in 2025, hampering manufacturing competitiveness in energy-intensive sectors like steel, chemicals, and aluminum. Major Italian manufacturers including Ferrari, Prada, and Ferrero have cited energy costs as factors in production location decisions.

Nuclear power could address these challenges by providing price-stable baseload power with 60+ year asset lives. France's nuclear-heavy grid delivers electricity at roughly half Italy's wholesale costs, demonstrating potential economic benefits of nuclear deployment.

Energy security concerns have intensified since 2022, with Italy scrambling to replace 29 billion cubic meters of annual Russian gas imports. Nuclear power offers domestic energy production immune to geopolitical supply disruptions, though Italian deployment would still require imported uranium enrichment services and nuclear fuel assemblies.

What regulatory challenges must Italy overcome?

Italy must establish entirely new nuclear regulatory frameworks, having dismantled most nuclear oversight capabilities after 1987. The country lacks both technical expertise and institutional knowledge for modern nuclear licensing, creating significant regulatory development challenges.

The Italian government will likely need to establish nuclear safety authority with international cooperation, potentially modeling approaches on successful programs in Poland, which restarted nuclear development after decades of suspension. International Atomic Energy Agency assistance programs could provide technical support for regulatory framework development.

Public acceptance remains Italy's most significant challenge, with polling showing nuclear support fluctuating between 35-45% depending on survey methodology and question framing. Local siting approval processes could prove particularly difficult, requiring careful community engagement strategies and significant economic incentive packages.

EU regulatory harmonization efforts could accelerate Italian nuclear development by enabling European-certified designs to streamline domestic approval processes. However, Italy would still require site-specific licensing, emergency planning coordination, and waste management arrangements before any nuclear deployment.

Market implications for nuclear industry

Italy's nuclear return announcement validates broader European nuclear renaissance trends, with potential market opportunities exceeding €20-30 billion over two decades depending on deployment scale and technology choices.

SMR developers specifically benefit from Italy's announcement, as the country represents one of Europe's largest potential markets with substantial industrial energy demand. Italian deployment could provide crucial European reference projects for companies seeking to scale internationally.

The announcement may accelerate European HALEU supply chain development, as many advanced reactor designs require higher-enriched uranium unavailable from current European facilities. Italy's nuclear program could justify European enrichment infrastructure investments currently stalled by uncertain demand forecasts.

Italian nuclear development would also impact European electricity markets by reducing Italy's import demand and potentially enabling electricity exports during periods of renewable energy intermittency. This market integration effect could influence neighboring countries' own nuclear deployment strategies.

Key Takeaways

• Italy's Prime Minister confirmed government preparing nuclear framework launch within months, ending 37-year nuclear moratorium
• Country imports 77% of electricity needs at costs 40% above EU averages, creating economic incentives for domestic nuclear power
• SMR technologies likely preferred over large reactors due to public acceptance and deployment timeline advantages
• New nuclear regulatory framework required from scratch, presenting both challenges and opportunities for international cooperation
• Market opportunity could exceed €20-30 billion, benefiting European SMR developers and nuclear supply chain companies

Frequently Asked Questions

When could Italy's first new nuclear plant begin operation? Based on typical SMR development timelines, Italy's first new nuclear plant could begin operation in the early-to-mid 2030s, assuming regulatory framework completion by 2027-2028 and successful technology selection and siting processes.

Which nuclear technologies are most likely for Italian deployment? Small modular reactors represent the most probable choice, with European companies like Newcleo, Rolls-Royce SMR, and French Nuward design as leading candidates due to smaller footprints and enhanced safety features addressing public acceptance concerns.

How would nuclear power affect Italian electricity prices? Nuclear deployment could reduce Italian electricity costs by 20-30% over time by replacing expensive imports and providing price-stable baseload generation, though initial costs would be higher during construction phases.

What happened to Italy's previous nuclear program? Italy operated four nuclear plants generating 3.9 GWe until a 1987 referendum following Chernobyl led to nuclear phase-out. The last plant closed in 1990, and Italy has relied primarily on fossil fuel imports since then.

How does Italy's nuclear return affect European energy markets? Italian nuclear deployment would reduce European electricity import demand and could enable Italy to become a net exporter during periods of high renewable generation, potentially stabilizing regional grid operations and pricing.
