The water-water energetic reactor (WWER), [1] or VVER (from Russian: водо-водяной энергетический реактор; transliterates as vodo-vodyanoi enyergeticheskiy 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. [2]
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.
This category includes power stations with the VVER-440, VVER-1000, VVER-1200 reactors. Pages in category "Nuclear power stations using VVER reactors" The following 33 pages are in this category, out of 33 total.
The four power reactors are pressurized water reactors of the Soviet VVER-440 design. Annual electricity generation averages about 12,000 GWh. Upon development of a district heating supply network in the town of Trnava near Bohunice NPP, V2 switched to co-generation. Part of this system is a heat feeder line commissioned in 1987.
robust design with reinforced concrete containment with walls thick up to 1.5 m; triple redundancy safety systems (3 x 100%) high level of passive safety. [7] Water flowing from the units' VVER-440 reactors to primary circuit heat exchangers has a temperature of about 297 °C. Cooling is by cooling towers. [7]
Most units use VVER pressurized water reactor (PWR) technology supplied from Russia. The first four units are Russian standard reactors of type VVER-1000, and have capacity approximately 1 GW. Units 5 and 6 are Chinese-designed ACPR-1000 reactors, with a traditional 3-loop system. Units 7 and 8 will use the updated VVER-1200 design capable of ...
The nuclear plant has six Soviet-designed VVER-1000 V-320 water-cooled and water-moderated reactors containing Uranium 235, and also has spent nuclear fuel at the facility.
