Novovoronezh Nuclear Power Plant II, Russia
Novovoronezh nuclear power plant II (NNPPII) is being built at the site of the existing Novovoronezh nuclear plant located in Voronezh Oblast, central Russia.
The project is being carried out as part of the Russian Government's long-term federal target programme (FTP), which entails making nuclear electricity account for 25%-30% of the country's total electricity supply by 2030, with further increases to 45%-50% by 2050 and 70%-80% by end of the century. The current share of nuclear electricity in the total electricity supply in Russia is 16%.
Novovoronezh II is planned to have four generating units featuring VVER-1200 reactors. Two of these reactors are being constructed as part of Phase 1.
The first unit was commissioned in February 2017 and the second unit is scheduled for completion in 2018. The other two units are still in the design stage.
Novovoronezh is one of ten nuclear power plants (NPP) being operated by the state-owned utility Rosenergoatom in Russia. With 33 reactors and a total installed capacity of 25.2GW, Rosenergoatom is the second largest utility in the world in nuclear electricity generation.
Plant details of existing Novovoronezh NPP
Novovoronezh is the first Russian NPP to have Water-Water Energetic Reactors (VVER). It has seen commissioning of five VVER reactors in its history, with its first unit equipped with VVER-210 and commissioned in 1964. The second, third, fourth, and fifth units were equipped with VVER-365, VVER-440, VVER-440, and VVER-1000, and were commissioned in 1969, 1971, 1972, and 1980, respectively.
At present, the plant is operating with only three reactors, as the first and second units were permanently decommissioned in 1988 and 1990.
The Novovoronezh plant supplies power to Voronezh Oblast, Belgorod, Lipetsk, and Tambov regions.
Unit 5 of the plant has recently undergone a $453m upgrade. It has advanced features similar to those of a generation III reactor and will operate until 2035.
Unit 3 of the plant was decommissioned in 2016, while unit four is scheduled for decommissioning in 2017.
Construction of Novovoronezh nuclear power plant II
Construction of the first unit of the Novovoronezh II plant started in 2008 and the second unit began in 2009. Foundation plates for both the units were complete by the end of 2009. Each plate required approximately 17,000t of concrete and 2,500t of reinforcement steel.
Concreting of the foundations for the cooling towers of both units was completed by October 2012.
Installation of circulation pumps at Unit 1 started in August 2012. The steam generator for Unit 1 was installed in September 2012 and installation of the reactor building dome had also started by November of the following year.
Novovoronezh II plant make-up
The new NPP will be equipped with four VVER reactors rated at 1,200MW each and four PGV-1000 steam generators along with generator sets and 12 N-caption filters.
Each steam generator has a diameter of 4.5m and height of 5.2m, weighing around 430t. The plant has an estimated life of 60 years. The generator sets will be used for emergency power supply.
The N-caption filter is a vessel that will operate with a pressure of 8.4MPa. It has a diameter of 2m with a height of 5m, and contains special filtering elements.
Reactor details of Novovoronezh nuclear power station
VVER-1200 has been designed to produce 1,200MWe of power with optimised fuel efficiency. It was planned to have a lifetime of around 60 years at 90% capacity factor.
VVER technology refers to a series of pressurised water reactor designs originally developed in Russia. The Russian abbreviation for VVER stands for 'water-cooled, water-moderated energy reactor'. Distinctive features of VVER include the horizontal steam generators, hexahedral fuel assemblies, and the high-capacity pressurisers that provide a large reactor coolant inventory.
The reactor offers adequate emergency solutions, including a core cooling system, a backup diesel power supply, an advanced refuelling machine, computerised reactor control systems, a backup feedwater supply, and reactor SCRAM system.
Contractors involved with the Novovoronezh II nuclear project
Russia's Rosatom Atomic Power Agency is building eight 70MW FNPS (Floating Nuclear Powered Stations) to be stationed around the country.
SStroytransgaz was awarded the contract for the construction-assembly work of the new power plant.
German diesel and gas manufacturer Tognum will supply MTU Onsite Energy emergency gensets worth $37m under a sub-contract with Zvezda Energetika.
Part of OMZ Group, Glazovsky zavod Khimmash supplied 12 N-caption filters for the power plant under a sub-contract signed on July 2009.
OKB GIDROPRESS designed the VVER reactors.
Machine building plant ZIO-Podolsk is responsible for the engineering and technical assistance of the steam generators. It transported the first generator to the plant site in February 2012.
Engineering company ZIOMAR has developed detailed drawing and packaging of the generators.
Power Machine is responsible to design, manufacture, and supply turbine units including the steam turbines, capacitors, and turbine generator sets.
AREVA will provide safety instrumentation and control systems for the four nuclear reactors at Novovoronezh II as part of a contract signed in 2009.
Atomenergoproekt was appointed as a general contractor for the design and construction of the Novovoronezh NPP-2.
ARAKO is the supplier of valves to the Novovoronezh II NPP.
Russia's nuclear power market and investments
The Russian power industry, especially the nuclear sector, has witnessed massive state investment recently.
The Federal Grid Company (RAO FGC), which owns Russia's 118,000km high-voltage transmission grid, invested $14.5bn during the 2010-2013 period to modernise its grid infrastructure to efficiently handle anticipated future increase in power production.
In July 2012, the Russian Energy Ministry published a draft plan to add 83GWe of new capacity with a total investment of RUR8,230bn ($266.3bn), considering the increasing domestic demand and the export potential. The nuclear component of the new capacity accounts for 10GWe with an investment of RUR1,320bn ($47.2bn).
Russia had formally initiated a $55bn nuclear energy development programme in October 2006. It includes $26bn of allocation from the federal budget until 2015 and the rest from the industry (Rosatom) funds.
The Federal Target Programme (FTP) approved in 2010 aims to accelerate nuclear power production with the use of fast reactors, as well as promoting export of nuclear technology.
Russia produced 196.3 billion kWh of nuclear power in 2016, which was 18.6% of the country's total electricity supply.
