A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. As of September 2023, the International Atomic Energy Agency reported there were 410 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction.
Pilgrim Nuclear Power Station (PNPS) is a closed nuclear power plant in Massachusetts in the Manomet section of Plymouth on Cape Cod Bay, south of the tip of Rocky Point and north of Priscilla Beach. Like many similar plants, it was constructed by Bechtel, and was powered by a General Electric BWR 3 boiling water reactor inside of a Mark 1 pressure suppression type containment and generator. With a 690 MWe production capacity, it produced about 14% of the electricity generated in Massachusetts.
The Paks Nuclear Power Plant is located 5 kilometres (3.1 mi) from the small town of Paks, central Hungary, 100km southwest of Budapest on the shores of the Danube river. It is the first and only operating nuclear power station in Hungary. In 2019, its four reactors produced more than 50% of Hungary's electricity production.
The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor. The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba. The ABWR generates electrical power by using steam to power a turbine connected to a generator; the steam is boiled from water using heat generated by fission reactions within nuclear fuel. Kashiwazaki-Kariwa unit 6 is considered the first Generation III reactor in the world.
Forsmark Nuclear Power Plant is a nuclear power plant in Forsmark, Sweden that provides 14% of Sweden's total electricity output, and also the site of the Swedish Final repository for radioactive operational waste. It is operated by a company mainly owned by Vattenfall.
The water-water energetic reactor (WWER), or VVER is a series of pressurized water reactor designs originally developed in the Soviet Union, and now Russia, by OKB Gidropress. The idea of such a reactor was proposed at the Kurchatov Institute by Savely Moiseevich Feinberg. VVER were originally developed before the 1970s, and have been continually updated. As a result, the name VVER is associated with a wide variety of reactor designs spanning from generation I reactors to modern generation III+ reactor designs. Power output ranges from 70 to 1300 MWe, with designs of up to 1700 MWe in development. The first prototype VVER-210 was built at the Novovoronezh Nuclear Power Plant.
Since the mid 1980s, the largest source of electricity in France has been nuclear power, with a generation of 379.5 TWh in 2019 and a total electricity production of 537.7 TWh. In 2018, the nuclear share was 71.67%, the highest percentage in the world.
The Krško Nuclear Power Plant is located in Vrbina in the City Municipality of Krško, Slovenia. The plant was connected to the power grid on October 2, 1981, and went into commercial operation on January 15, 1983. It was built as a joint venture by Slovenia and Croatia which were both part of Yugoslavia at the time.
Nuclear power in Switzerland is generated by three nuclear power plants, with a total of four operational reactors (see list below). Nuclear power has contributed a steady fraction of around forty percent to the Swiss electricity production since 1985. In 2022, it produced 23 terawatt-hours (TWh) of electricity, and accounted for 37% of the nation's gross electricity generation of 62 TWh, while 55% was produced by hydroelectric plants and 8% came from conventional thermal power stations and non-hydro renewable energy sources.
Santa María de Garoña Nuclear Power Plant is a mothballed nuclear power station at Santa María de Garoña, Burgos (Spain). It consists of one boiling water reactor (BWR) of 466 megawatts (MWe).
Spain has five active nuclear power plants with seven reactors producing 21% of the country's electricity as of 2013.
Portugal and Spain enjoy a friendly relationship. They are both members of the Ibero-American Summit, Council of Europe, European Union, Eurozone, Schengen Area and NATO, and make up the vast majority of the Iberian Peninsula.
Nuclear power in the European Union accounted for approximately 26% of total electricity production in 2019 and nearly half of low-carbon energy production across the EU.
The Doel Nuclear Power Station is one of two nuclear power plants in Belgium. The plant includes four reactors. The site is located on the bank of the Scheldt river, near the village of Doel in the Flemish province of East Flanders, on the outskirts of the city of Antwerp. The station is operated and majority-owned by vertically-integrated French energy corporation Engie SA through its 100%-owned Belgian subsidiary Electrabel. EDF Luminus has a 10.2% stake in the two newest units. The Doel plant employs 963 workers and covers an area of 80 hectares. The plant represents about 15% of Belgium's total electricity production capacity and 30% of the total electricity generation. Nuclear energy typically provides half of Belgium's domestically-generated electricity and is the country's lowest-cost source of power.
The Tihange Nuclear Power Station is one of two nuclear energy power plants in Belgium and contains three nuclear reactors. The site is located on the bank of the Meuse river, near the village of Tihange in the Walloon province of Liège. The station is operated and majority-owned by vertically-integrated Belgian energy corporation Electrabel. EDF Luminus has a 50% stake in the oldest unit and a 10% stake in the two newest units. It employs 1074 workers and covers an area of 75 hectares. The plant represents about 15% of Belgium's total electricity production capacity. Nuclear energy typically provides between 40%-50% of Belgium's domestically-generated electricity. In order to extend the lifetime of Tihange 3, the operator will receive subsidies through a Contract of Difference arrangement.
The late 1950s and early 1960s saw a strong push from the Spanish Government to establish a national nuclear power industry. In response to the surge in nuclear power plant plans, a strong anti-nuclear movement emerged in 1973, which ultimately impeded the realisation of most of the projects.
The Energy Multiplier Module is a nuclear fission power reactor under development by General Atomics. It is a fast-neutron version of the Gas Turbine Modular Helium Reactor (GT-MHR) and is capable of converting spent nuclear fuel into electricity and industrial process heat.
The Association of Regulators of Western Europe (WENRA), created on 4 February 1999, is an association of agencies or regulatory agencies in the field of nuclear countries of Western Europe.
The Fukushima Daiichi reactor, was 1 out of 4 reactors seriously affected during the Fukushima Daiichi nuclear disaster on 11 March 2011. Overall, the plant had 6 separate boiling water reactors originally designed by General Electric (GE), and maintained by the Tokyo Electric Power Company (TEPCO). At the time of the earthquake, Reactor 4 had been de-fueled while 5 and 6 were in cold shutdown for planned maintenance.
The Nuclear Safety Council is the independent Spanish institution of the General State Administration, whose main purpose is to ensure nuclear safety and the radiation protection of people and the environment. Its structure, functions, competencies and organization were extensively modified in October 2007 with law reforms. It is also a member of the Western European Nuclear Regulators' Association.
