The water-water energetic reactor (WWER), : водо-водяной энергетический реактор; transliterates as vodo-vodyanoi energetichesky reaktor; water-water power reactor) 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.or VVER (from Russian
VVER power stations have been mostly installed in Russia and the former Soviet Union, but also in China, Czech Republic, Finland, Germany, Hungary, Slovakia, Bulgaria, India, and Iran. Countries that are planning to introduce VVER reactors include Bangladesh, Egypt, Jordan, and Turkey.
The earliest VVERs were built before 1970. The VVER-440 Model V230 was the most common design, delivering 440 MW of electrical power. The V230 employs six primary coolant loops each with a horizontal steam generator. A modified version of VVER-440, Model V213, was a product of the first nuclear safety standards adopted by Soviet designers. This model includes added emergency core cooling and auxiliary feedwater systems as well as upgraded accident localization systems.
The larger VVER-1000 was developed after 1975 and is a four-loop system housed in a containment-type structure with a spray steam suppression system (Emergency Core Cooling System). VVER reactor designs have been elaborated to incorporate automatic control, passive safety and containment systems associated with Western generation III reactors.
The VVER-1200 is the version currently offered for construction, being an evolution of the VVER-1000 with increased power output to about 1200 MWe (gross) and providing additional passive safety features.
In 2012, Rosatom stated that in the future it intended to certify the VVER with the British and U.S. regulatory authorities, though was unlikely to apply for a British licence before 2015.
The construction of the first VVER-1300 (VVER-TOI) 1300 MWE unit was started in 2018.
The Russian abbreviation VVER stands for 'water-water energy reactor' (i.e. water-cooled water-moderated energy reactor). The design is a type of pressurised water reactor (PWR). The main distinguishing features of the VVERcompared to other PWRs are:
Reactor fuel rods are fully immersed in water kept at (12,5 / 15,7 / 16,2 ) MPa pressure respectively so that it does not boil at the normal (220 to over 320 °C) operating temperatures. Water in the reactor serves both as a coolant and a moderator which is an important safety feature. Should coolant circulation fail, the neutron moderation effect of the water diminishes due to increased heat which creates steam bubbles which do not moderate neutrons, thus reducing reaction intensity and compensating for loss of cooling, a condition known as negative void coefficient. Later versions of the reactors are encased in massive steel reactor pressure vessels. Fuel is low enriched (ca. 2.4–4.4% 235U) uranium dioxide (UO2) or equivalent pressed into pellets and assembled into fuel rods.
Reactivity is controlled by control rods that can be inserted into the reactor from above. These rods are made from a neutron absorbing material and, depending on depth of insertion, hinder the chain reaction. If there is an emergency, a reactor shutdown can be performed by full insertion of the control rods into the core.
As stated above, the water in the primary circuits is kept under a constant elevated pressure to avoid its boiling. Since the water transfers all the heat from the core and is irradiated, the integrity of this circuit is crucial. Four main components can be distinguished:
To provide for the continued cooling of the reactor core in emergency situations the primary cooling is designed with redundancy.
The secondary circuit also consists of different subsystems:
To increase efficiency of the process, steam from the turbine is taken to reheat coolant before the deaerator and the steam generator. Water in this circuit is not supposed to be radioactive.
The tertiary cooling circuit is an open circuit diverting water from an outside reservoir such as a lake or river. Evaporative cooling towers, cooling basins or ponds transfer the waste heat from the generation circuit into the environment.
In most VVERs this heat can also be further used for residential and industrial heating. Operational examples of such systems are Bohunice NPP (Slovakia) supplying heat to the towns of Trnava km away), Leopoldov (9.5 km away), and Hlohovec (13 km away), and Temelín NPP (Czech Republic) supplying heat to Týn nad Vltavou 5 km away. Plans are made to supply heat from the Dukovany NPP to Brno (the second-largest city in the Czech Republic), covering two-thirds of its heat needs.(12
A typical design feature of nuclear reactors is layered safety barriers preventing escape of radioactive material. VVER reactors have three layers:
Compared to the RBMK reactors – the type involved in the Chernobyl disaster – the VVER uses an inherently safer design. It does not have the graphite-moderated RBMK's risk of a power surge transient or criticality accident. Also the RBMK power stations were constructed without containment structures on grounds of cost. (Fuel elements in an RBMK can be replaced while the reactor is running at its nominal output, allowing the continuous operation and plutonium extraction compared to most pressurized water reactors like the VVER which need to be shut down to exchange fuel rod assemblies.)
One of the earliest versions of the VVER-type, that manifested certain problems with its Containment building-design. As it was at the beginning with the models V-230 and older not constructed to resist the design basis large pipe break, the manufacturer added with the newer model V-213 a so called Bubble condenser tower, that - with its additional volume and a number of water layers - has the aim to suppress the forces of the rapidly escaping steam without the onset of a containment-leak. As a consequence, all member-countries with plants of design VVER-440 V-230 and older were forced by the politicians of the European Union to shut them down permanently. Bohunice Nuclear Power Plant and Kozloduy Nuclear Power Plant had to close with this two respectively four of their units. Whereas in the case of the Greifswald Nuclear Power Plant, the German regulatory body had already taken the same decision in the wake of the fall of the Berlin wall.
When first built the VVER design was intended to be operational for 35 years. A mid-life major overhaul including a complete replacement of critical parts such as fuel and control rod channels was thought necessary after that.Since RBMK reactors specified a major replacement programme at 35 years designers originally decided this needed to happen in the VVER type as well, although they are of more robust design than the RBMK type. Most of Russia's VVER plants are now reaching and passing the 35 year mark. More recent design studies have allowed for an extension of lifetime up to 50 years with replacement of equipment. New VVERs will be nameplated with the extended lifetime.
In 2010 the oldest VVER-1000, at Novovoronezh, was shut down for modernization to extend its operating life for an additional 20 years; the first to undergo such an operating life extension. The work includes the modernization of management, protection and emergency systems, and improvement of security and radiation safety systems.
In 2018 Rosatom announced it had developed a thermal annealing technique for reactor pressure vessels which ameliorates radiation damage and extends service life by between 15 and 30 years. This had been demonstrated on unit 1 of the Balakovo Nuclear Power Plant.
The VVER-1200 (or NPP-2006 or AES-2006)is an evolution of the VVER-1000 being offered for domestic and export use. The reactor design has been refined to optimize fuel efficiency. Specifications include a $1,200 per kW overnight construction cost, 54 month planned construction time, a 60 year design lifetime at 90% capacity factor, and requiring about 35% fewer operational personnel than the VVER-1000. The VVER-1200 has a gross and net thermal efficiency of 37.5% and 34.8%. The VVER 1200 will produce 1,198 MWe of power.
The first two units have been built at Leningrad Nuclear Power Plant II and Novovoronezh Nuclear Power Plant II. More reactors with a VVER-1200/491like the Leningrad-II-design are planned (Kaliningrad and Nizhny Novgorod NPP) and under construction. The type VVER-1200/392M as installed at the Novovoronezh NPP-II has also been selected for the Seversk, Zentral and South-Urals NPP. A standard version was developed as VVER-1200/513 and based on the VVER-TOI (VVER-1300/510) design.
In July 2012 a contract was agreed to build two AES-2006 in Belarus at Ostrovets and for Russia to provide a $10 billion loan to cover the project costs.An AES-2006 is being bid for the Hanhikivi Nuclear Power Plant in Finland.
From 2015 to 2017 Egypt and Russia came to an agreement for the construction of four VVER-1200 units at El Dabaa Nuclear Power Plant.
On 30 November 2017, concrete was poured for the nuclear island basemat for first of two VVER-1200/523 units at Rooppur in Bangladesh.The Rooppur Nuclear Power Plant will be a 2.4 GWe nuclear power plant in Bangladesh.The two units generating 2.4 GWe are planned to be operational in 2023 and 2024.
On 7 March 2019 China National Nuclear Corporation (CNNC) and Atomstroyexport signed the detailed contract for the construction of four VVER-1200s, two each at the Tianwan Nuclear Power Plant and the Xudabao Nuclear Power Plant. Construction will start in May 2021 and commercial operation of all the units is expected between 2026 and 2028.
From 2020 an 18-month refuelling cycle will be piloted, resulting in an improved capacity utilisation factor compared to the previous 12-month cycle.
The nuclear part of the plant is housed in a single building acting as containment and missile shield. Besides the reactor and steam generators this includes an improved refueling machine, and the computerized reactor control systems. Likewise protected in the same building are the emergency systems, including an emergency core cooling system, emergency backup diesel power supply, and backup feed water supply,
A passive heat removal system had been added to the existing active systems in the AES-92 version of the VVER-1000 used for the Kudankulam Nuclear Power Plant in India. This has been retained for the newer VVER-1200 and future designs. The system is based on a cooling system and water tanks built on top of the containment dome.The passive systems handle all safety functions for 24 hours, and core safety for 72 hours.
Other new safety systems include aircraft crash protection, hydrogen recombiners, and a core catcher to contain the molten reactor core in the event of a severe accident.The core catcher will be deployed in the Rooppur Nuclear Power Plant and El Dabaa Nuclear Power Plant.
The VVER-TOI is developed from the VVER-1200. It is aimed at development of typical optimized informative-advanced project of a new generation III+ Power Unit based on VVER technology, which meets a number of target-oriented parameters using modern information and management technologies.
The main improvements from the VVER-1200 are:
The construction of the first two VVER-TOI units was started in 2018 and 2019 at the Kursk II Nuclear Power Plant.
In June 2019 the VVER-TOI was certified as compliant with European Utility Requirements (with certain reservations) for nuclear power plants.
An upgraded version of AES-2006 with TOI standards, the VVER-1200/513, is being built in Akkuyu Nuclear Power Plant in Turkey.
A number of designs for future versions of the VVER have been made:
Russia recently[ when? ] installed two nuclear reactors in China at the Tianwan Nuclear Power Plant, and an extension consisting of a further two reactors was just approved. This is the first time the two countries have co-operated on a nuclear power project. The reactors are the VVER 1000 type, which Russia has improved incrementally while retaining the basic design. These VVER 1000 reactors are housed in a confinement shell capable of being hit by an aircraft weighing 20 tonnes and suffering no expected damage. Other important safety features include an emergency core cooling system and core confinement system. Russia delivered initial fuel loads for the Tianwan reactors. China planned to begin indigenous fuel fabrication for the Tianwan plant in 2010, using technology transferred from Russian nuclear fuel producer TVEL.
The Tianwan Nuclear Power Plant uses many third party parts. While the reactor and turbo-generators are of Russian design, the control room was designed and built by an international consortium. In this way the plant was brought to meet widely recognised safety standards; safety systems were already mostly in place but the previous monitoring of these systems did not meet international safety standards. The new VVER 1000 plant built in China has 94% of its systems automated, meaning the plant can control itself under most situations. Refueling procedures require little human intervention. Five operators are still needed in the control room.
In May 2010 Russia secured an agreement with the Turkish government to build a power plant with four VVER-1200 reactors at Akkuyu, Turkey. [ citation needed ]However, due to the accident experienced in Fukushima, anti-nuclear environmentalist groups heavily protested the proposed reactor at Akkuyu.
On 11 October 2011 an agreement was signed to build Belarus’ first nuclear power plant at Astravyets, using two VVER-1200/491 (AES-2006) reactors with active and passive safety systems. In July 2016, the reactor vessel for unit 1 has hit the ground during transportation, and though no damage was sustained it was decided to be replaced to allay public fears, delaying the project by a year. Unit 1 is, as of April 2020, planned to commence operation in 2020.
In October 2013 the VVER-1000 (AES-92) design was selected by the Jordan Atomic Energy Commission in a competitive tender for Jordan's first twin reactor nuclear power station.
In November 2015 and March 2017 Egypt signed preliminary agreements with Russian nuclear company Rosatom for a first VVER-1200 unit at El Dabaa to start operations in 2024. Discussions continue for final approval.

A pressurized water reactor (PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants. In a PWR, the primary coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the fission of atoms. The heated, high pressure water then flows to a steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizontal steam generators.
A nuclear meltdown is a severe nuclear reactor accident that results in core damage from overheating. The term nuclear meltdown is not officially defined by the International Atomic Energy Agency or by the United States Nuclear Regulatory Commission. It has been defined to mean the accidental melting of the core of a nuclear reactor, however, and is in common usage a reference to the core's either complete or partial collapse.
A nuclear power plant 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 2018, the International Atomic Energy Agency reported there were 450 nuclear power reactors in operation in 30 countries around the world.
The RBMK is a class of graphite-moderated nuclear power reactor designed and built by the Soviet Union. The name refers to its unusual design where, instead of a large steel pressure vessel surrounding the entire core, the core is surrounded by a cylindrical annular steel tank inside a concrete vault and each fuel assembly is enclosed in an individual 8 cm diameter pipe surrounded in graphite which allows the flow of cooling water around the fuel.
The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator – furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor.
Rosatom, stylized as ROSATOM and also known as the Rosatom State Nuclear Energy Corporation, the State Atomic Energy Corporation Rosatom, or the Rosatom State Corporation, is a Russian state corporation headquartered in Moscow that specializes in nuclear energy. Established in 2007, the organization comprises more than 360 enterprises, including scientific research organizations, the nuclear weapons complex, and the world's only nuclear icebreaker fleet.
The Kola Nuclear Power Plant, also known as Kolsk NPP or Kolskaya NPP, is a nuclear power plant located 12 km away from Polyarnye Zori, Murmansk Oblast in north-western Russia.
A Generation III reactor is a development of Generation II nuclear reactor designs incorporating evolutionary improvements in design developed during the lifetime of the Generation II reactor designs. These include improved fuel technology, superior thermal efficiency, significantly enhanced safety systems, and standardized designs for reduced maintenance and capital costs. The first Generation III reactor to begin operation was Kashiwazaki 6 in 1996.
Russia is one of the world's largest producers of nuclear energy. In 2020 total electricity generated in nuclear power plants in Russia was 215.746 TWh, 20.28% of all power generation. The installed gross capacity of Russian nuclear reactors is 29.4 GW in December 2020.

Tianwan Nuclear Power Plant is a nuclear power plant (NPP) in the city of Lianyungang in Jiangsu Province, China. It is located on the coast of the Yellow Sea approximately 30 kilometers east of Lianyungang proper. It is co-owned by Jiangsu Nuclear Power Corporation, a joint venture partially owned by the China National Nuclear Corporation (CNNC), and Atomstroyexport (ASE), the nuclear equipment exporter branch of the Russian nuclear corporation Rosatom.
Novovoronezh Nuclear Power Plant II is a Russian nuclear power plant with two 1200 MW pressurized water reactors (VVER) located in Voronezh Oblast. The power plant is built on the same site as the present Novovoronezh Nuclear Power Plant.
The Kaliningrad Nuclear Power Plant is a nuclear power plant under construction 13 kilometres (8.1 mi) south-east of Neman, in Kaliningrad Oblast, Russia. It is seen as a counter-project to the plan to build the Visaginas nuclear power plant in Lithuania and is considered not only as an energy, but also as a geopolitical project. In June 2013 the construction was temporarily stopped for the project to be redesigned.
A core catcher is a device provided to catch the molten core material (corium) of a nuclear reactor in case of a nuclear meltdown and prevent it from escaping the containment building.
The VVER-TOI or WWER-TOI is a generation III+ nuclear power reactor based on VVER technology developed by Rosatom. The VVER-TOI design is intended to improve the competitiveness of Russian VVER technology in international markets. It would use VVER-1300/510 water pressurized reactors constructed to meet modern nuclear and radiation safety requirements.
The BN-800 reactor is a sodium-cooled fast breeder reactor, built at the Beloyarsk Nuclear Power Station, in Zarechny, Sverdlovsk Oblast, Russia. The reactor is designed to generate 880 MW of electrical power. The plant was considered part of the weapons-grade Plutonium Management and Disposition Agreement signed between the United States and Russia, with the reactor being part of the final step for a plutonium-burner core. The plant reached its full power production in August, 2016. According to Russian business journal Kommersant, the BN-800 project cost 140.6 billion rubles.
The BN-1200 reactor is a sodium-cooled fast breeder reactor project, under development by OKBM Afrikantov in Zarechny, Russia. The BN-1200 is based on the earlier BN-600 and especially BN-800, with which it shares a number of features. The reactor's name comes from its electrical output, nominally 1220 MWe.
