The water-water energetic reactor (WWER), [1] or VVER (from Russian: водо-водяной энергетический реактор, romanized: vodo-vodyanoi enyergeticheskiy reaktor, lit. 'water-water power reactor') is a series of pressurized water reactor designs originally developed in the Soviet Union, and now Russia, by OKB ...

Jan 5, 2006 · The VVER is the Russian version of the Pressurized Water Reactor (PWR). There are 3 standard designs - two 6 loop- 440 Megawatt [440-230 (older) and 440-213 (newer)] and 4 loop-1000 Megawatt output designs.

An emerging leader in the VVER fuel market with our next-generation products. Fuel Westinghouse continues to expand the VVER market with support of reliable fuel products.

VVER reactors are a series of Pressurised Water Reactors (PWRs), originally designed by OKB Gidropress – a subsidiary of ROSATOM – Russian state nuclear corporation, while the nuclear power stations employing VVER technology have been developed by the power plant design institutions within ROSATOM, such as Moscow ATOMENERGOPROEKT (AEP), St. Pete...

El Dabaa Nuclear Power Plant is the first nuclear power plant planned for Egypt and will be located at El Dabaa, Matrouh Governorate, Egypt, about 320 kilometers northwest of Cairo. [5][6] The plant will have four VVER-1200 reactors, making Egypt the only country in the region to have a Generation III+ reactor. [7][8]

VVER reactors are the most frequently built reactor type in the world. Presently, there are 23 units of VVER-440 and 28 units of VVER-1000 worldwide in operation (see tables in Sects. 2.3 and 3.3). In the introduction, a historical overview on the design of VVER-440 and VVER-1000 reactors is given.

Dec 1, 2017 · In the critical period after the accident at the Chernobyl NPP, it was the VVER reactors that ensured the stability of domestic nuclear power. The latest new-generation first-of-the-kind power unit based on the VVER technology was commissioned at the NvNPP site.

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.

Jan 1, 2024 · The evolution of VVER (veda-vodyanoi energetichesky reaktor—water cooled power reactor) reactors started in the former Soviet Union in 1955 and continues with the development of new designs in the Russian Federation until now. Over the years, many different versions of VVER designs have been developed.

The United States Department of Energy is compiling information to better understand Soviet nuclear power plants. This report provides information concerning the VVER, the Soviet designed pressurized water reactor.
