Nuclear power in Italy is a controversial topic.Italy started to producenuclear energy in the early 1960s, but all plants were closed by 1990 following the1987 referendum.As of 2023, Italy is one of only three countries, along withLithuania andGermany, that completely phased out nuclear power for electricity generation after having operational reactors.
An attempt to change the decision was made in 2008 by the government (see alsonuclear power debate), which called thenuclear power phase-out a "terrible mistake, the cost of which totalled over €50 billion".[1]Minister of Economic DevelopmentClaudio Scajola proposed to build as many as 10 new reactors, with the goal of increasing the nuclear share of Italy's electricity supply to about 25% by 2030.[2]
However, following the2011 Japanese nuclear accidents, the Italian government put a one-year moratorium on plans to revive nuclear power.[3]On 11–12 June 2011, Italian voters passeda referendum to cancel plans for new reactors. Over 94% of the electorate voted in favor of the construction ban, with 55% of the eligible voters participating, making the vote binding.[4]
There are no nuclear power plants in operation in Italy. List of previously operational nuclear power plants:

The history of nuclear power in Italy starts at the end of 1946, when theCise, a small centre for nuclear energy research, was created. A few years later, a public research institute linked to theCNR, theCnrn (Comitato Nazionale per le Ricerche Nucleari, National Committee for Nuclear Research), was founded. TheCnrn became an autonomous research entity in 1960, theCnen (Comitato Nazionale per l'Energia Nucleare, National Committee for Nuclear Energy).[6]
During all the 1950s there was a common belief that nuclear energy would have provided within few years, safely and economically, all the energy needed. Italy ordered between 1956 and 1958 3 different reactors from 3 different companies:Westinghouse,General Electric and Npcc. The reactors were built inTrino Vercellese,Sessa Aurunca andLatina and were all completed by 1964.[7]
At that time electric companies in Italy were private and the power plants were built by different private companies. However theelectricity sector was nationalized in 1962 with the creation of a new corporation responsible for production and distribution of electricity in the country:Enel. This factor is thought to be the reason for Italy's halt in nuclear investments. In fact, only one reactor was ordered in the following decade: construction of the Caorso power plant started in 1970 and was completed in 1978.[8] At the same time, Italy initiated anuclear weapons program to produce its own nuclear weapons essentially under theItalian Navy control. CAMEN (then CISAM) close Pisa was used for this aim.[9] It was stopped in the '70s to join NATOnuclear sharing. For this sector Italy has produced the IRBMAlfa and other air vectors. The former Italian PresidentFrancesco Cossiga declared officially in Italy secrets about nuclear weapons subject like all military ones are generally hidden by silence or lies.[10]
Italy suffered much from the1973 oil crisis due to its dependency on imported oil. An attempt to change this potentially dangerous situation was made in the following years. The firstPEN (Piano Energetico Nazionale, National energy plan) was approved in 1975. The plan's objective was to lower the country's dependency on fossil fuels by making huge investments in the nuclear energy sector.[11] The document planned an installed nuclear energy capacity of more than 46 GW by 1990.[12] Subsequent plans downsized the commitment. However, by 1986, only one plant was under construction, inMontalto di Castro.
Following theChernobyl disaster in 1986, a debate on nuclear energy started in Italy and eventually led to the nuclear power referendum of November 1987, which polled voters on three issues:
Some commenters find that the questions were actually too technical for non-experts and were used to obtain popular consent afterChernobyl disaster.[13][14]This was caused by the fact that referendum in Italy can be onlyabrogative, therefore it can only cancel an act, it can not set a national energy program.
In each referendumSì ("Yes") won. Subsequently, the Italian government decided in 1988 to phase out existing plants. This led to the termination of work on the near-completeMontalto di Castro Nuclear Power Station, and the early closure ofEnrico Fermi andCaorso Nuclear Power Plant, both of which closed in 1990. Italy's other nuclear power plants had already closed prior to the decision. The Montalto di Castro plant was subsequently converted to theAlessandro Voltafossil fuel power station.
In later years, Italy became a larger importer of power, importing approximately 10% of its electricity fromFrance by 2007.
On 13 November 2007, during his speech at theWorld Energy Council in Rome, Italy's nuclear stance was criticized by CEO ofEni,Paolo Scaroni.[15]In January 2008, a think tank Energy Lab started a feasibility study for construction of three or four new nuclear power plants in Italy as a part of a new debate on nuclear power in the country.[16] TheItalian general election of April 2008 saw the victory of thePeople of Freedom, a party which strongly supports nuclear power.[17] Following the election victory, the new Italy's Minister for Economic Development Claudio Scajola announced the scheduling for the start of the construction of a new nuclear-powered plant by 2013.[18]
Enel S.p.A. planned to build new reactors at one of three licensed sites:Garigliano,Latina, orMontalto di Castro. The first two had small reactors operating until 1982 and 1987. At Montalto di Castro two larger reactors were nearly completed when the country's referendum halted the construction in November 1987.[19]
On 24 February 2009, a new agreement betweenFrance and Italy was signed, thus allowing Italy to share in France's expertise in the area of nuclear power station design. Under the agreement, a study was to be conducted to determine the feasibility of building 4 new nuclear power stations in Italy.[20]On 9 July 2009 the Italian legislature passed an energy bill covering the establishment of a Nuclear Regulatory Agency and giving the government six months to select sites for new plants.[21]
However, the nuclear agenda ofSilvio Berlusconi's government was slowed down due to the strong opposition of ten Italian regions (Basilicata,Calabria,Emilia-Romagna,Lazio,Liguria,Marche,Molise,Apulia,Tuscany andUmbria), that challenged the energy bill passed on 9 July 2009 (the part that gives the government the responsibility for the reopening of nuclear facilities in the country) because they deemed it asunconstitutional. On 24 June 2010 the Italian Constitutional Court rejected the appeal, but the Italian government had to approve a new version of the Legislative Decree 31/2010 on nuclear sites, in order to adapt it to the decision of the Constitutional Court. The members of the Nuclear Regulatory Agency were named by the government only on 5 November 2010 and the list sent to the Italian Parliament for approval.[22]On 1 December 2010 a joint meeting of the Italian Parliament commissions for the Environment and for Productive Activities rejected one of the nominations putting a further stop to the Italian government plans.
On 3 August 2009, Enel andÉlectricité de France established a joint venture,Sviluppo Nucleare Italia Srl, for studying the feasibility of building at least four reactors usingAreva'sEuropean Pressurized Reactors.[23]
The Italian government put a one-year moratorium on its plans to revive nuclear power, following the2011 Japanese nuclear accidents.[3] Afurther Italian nuclear power referendum was held on 13 June 2011, with a 54.79% turnout and 94% of the votes rejecting the use of Nuclear Power,[24] leading to cancellations of any future nuclear power plants planned during the previous years.
After the closure of the plants, the government decided for a "deferred dismantling" policy, sending the spent fuel rods to be reprocessed in other countries and keeping the plants monitored. In 1999 the government changed policy, deciding to speed up the dismantling of the plants.
Nuclear power plants in Italy are currently being decommissioned bySOGIN, a company under control of theItalian Ministry of Economy and Finance.[25] The company is responsible for the handling of nuclear waste and the dismantling and decontamination of decommissioned power plants. SOGIN also manages nuclear waste from other applications, such as medical devices and scientific centers.[26]
There are plans for the construction of a unique surface storage site for all the Italian nuclear waste, of which about 70% comes from old nuclear power plants.[27] These highly radioactive materials are currently being reprocessed to reduce the total volume.[26]
In the nuclear sector, Italy participates in the development of theITER fusion reactor to produce clean energy throughENEA.[28]
