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.
VVER is the Soviet designation for a pressurized water reactor.The number following VVER, in this case 440, represents the power output of the original design. The VVER-440 Model V213 was a product of the first uniform safety requirements drawn up by the Soviet designers.
The reactors are pressurised water reactor of Russian design, model VVER-1000/V-412 referred also as AES-92. Thermal capacity is 3,000 MW, gross electrical capacity is 1,000 MW with a net capacity of 917 MW. [ 29 ]
Schematic diagram of an RBMK Schematic side view of the layout of an RBMK reactor core The reactor hall and piping systems of the RBMK reactor. The reactor pit or vault is made of reinforced concrete and has dimensions 21.6m × 21.6m × 25.5m. It houses the vessel of the reactor, which is annular, made of an inner and outer cylindrical wall and ...
It consists of two 1200 MWe VVER-1200 reactors. The nuclear power plant is being constructed at Rooppur of Ishwardi Upazila on the bank of the river Padma , about 160 km northwest of Dhaka . [ 6 ] It will be the country's first nuclear power plant , and the first of the two units is expected to go into operation in 2025.
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. ...
The pressurized water reactor has several new Generation III reactor evolutionary designs: the AP1000, VVER-1200, ACPR1000+, APR1400, Hualong One, IPWR-900 and EPR. The first AP1000 and EPR reactors were connected to the power grid in China in 2018. [7]
