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 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 reactors are light-water-moderated and water-cooled i.e. pressurized water reactors (PWRs). The name comes from Russian “ -я эч а ” which transliterates as Vodo-Vodyanoi Energetichesky Reaktor (Water-Water Energetic Reactor WWER but the Russian type acronym VVER is more often used). The VVERs were developed in the 1960s.

Aug 26, 2011 · VVER fuel update Russia now supplies almost a fifth of the world’s nuclear fuel. TVEL’s fuel development programmes for Russian-designed VVER light water reactors in Russia and abroad aim to increase the service life, burn-up and cost effectiveness of its fuel assemblies.

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.

R&D activity, performed by Russian institutes, design bureaus and factories, allowed to create nuclear fuel for VVER reactors of new generation with basic technical and economic indices (burnup, life time, etc.) conforming with the standards …

Dec 21, 2016 · The two-unit VVER-TOI nuclear station project has evolved from AES-2006, a design implemented in the Novovoronezh station under construction. Its major advantage is that most solutions it employs are time-proven and have …
