According to the 2020 corporate report, its 10-year foreign order portfolio stood at $ 138.3 billion, while revenue reached $ 7.5 billion. The 10-year order portfolio for new products stood at ₽1,602.1 billion while revenue reached ₽261.1 billion. Several Soviet and Russian government entities with different tasks are among the Rosatom predecessors. On 26 June 1953,

6068-442: 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 VVER-1200 is designed to be capable of varying power between 100% and 40% for daily load following, which was tested in 2024. The nuclear part of the plant is housed in a single building acting as containment and missile shield. Besides

6150-422: The world's largest nuclear plant, surpassing both the active Kori NPP (7,411 MWe) and the inactive Kashiwazaki-Kariwa NPP (7,965 MWe). The Tianwan nuclear power plant has six operating units and two under construction: The Tianwan reactor's genesis is a 1992 nuclear cooperation agreement between Russia and China. Regulators approved the initial design in 1997, and construction commenced on unit 1 in 1999 and

6232-539: Was a leak or explosion. On 28 June 2017, The Financial Times criticized Rosatom for lack of transparency regarding an alleged expansionist agenda through its role as a " Kremlin-controlled company ". On 20 March 2018, this criticism was underlined by the Bellona Foundation , who focused on the scarce data available on Rosatom's progress in Sudan . On 20 August 2020, Rosatom marked the 75th anniversary of

6314-558: Was around $ 2 billion in FY2023 and considered this unacceptable. The European Union dares not sanction Rosatom because of the clout it wields on the continent, although the European Parliament did call for sanctions as lately as 2 February 2023. Within the next two days after Russian military forces occupied Ukraine's Chernobyl Nuclear Power Plant on 24 February 2022, Rosatom employees had gained unauthorized access to

6396-561: Was built at the Novovoronezh Nuclear Power Plant . VVER power stations have been installed in Russia, Ukraine, Belarus, Armenia, China, the Czech Republic, Finland, Hungary, Slovakia, Bulgaria, India, and Iran. Countries that are planning to introduce VVER reactors include Bangladesh, Egypt, Jordan, and Turkey. Germany shut down its VVER reactors in 1989-90, and cancelled those under construction. The earliest VVERs were built before 1970. The VVER-440 Model V230

6478-419: 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

6560-510: Was engaged in foreign construction, and a number of independent engineering institutes with the name Atomenergoproekt were engaged in the design and construction of facilities in Russia: Moscow , St. Petersburg , and Nizhny Novgorod. Since October 2014 on the basis of NIAEP-ASE, Rosatom forms a unified engineering division, not including design company on nuclear power facilities and technologies Atomproekt. According to Kommersant , such

6642-472: Was signed in 2013, but terminated in 2022 mainly due to Russian invasion of Ukraine. 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 the Rooppur Nuclear Power Plant in Bangladesh . The power plant will be
