Russia’s Titan-2 holding (part of Rosatom) has signed a contract for the construction of units 7&8 at the Leningrad NPP (LNPP), also known as Leningrad-II 3&4, with VVER-1200 reactors. Titan-2 the general contractor for the project and is now beginning preparatory work such as deforestation. The next step will be the vertical planning of the territory, which will prepare the industrial site for the development of pits.
During the construction of Leningrad-II units 1&2, Titan-2 specialists used unique construction technologies including open top installation technology. This method makes it possible to install large equipment in the reactor building through an open dome, which significantly reduces construction time and provides the customer with timely commissioning and preparation of the power unit for launch. This is now widely used by the holding's specialists at other construction sites, including the Akkuyu NPP in Turkey.
The holding's specialists plan to complete all the preparatory work at Leningrad by the end of this year in order to launch full scale construction next year.
In June, Sergey Prokhor, Chief Engineer of the LNPP Capital Construction Department said the two new units would begin construction in 2024 and 2025 for completion in 2030 and 2032.
First concrete for unit 7 is expected in June 2024 and for unit 8 in May 2025.
Currently Leningrad NPP has four units in operation – the original units 3&4 with Soviet RBMK-1000 reactors, as well units 5&6 (or LNPP-II 1&2) with new VVER-1200 units. Units 5&6 replaced units 1&2 with RBMK-1000 reactors, which were decommissioned in 2018 and 2020. The new units 7&8 will replace the original units 3&4.
