Rosatom has issued a permit to nuclear utility Rosenergoatom for the first stage of construction of VVER-1200 power units 7&8 of the Leningrad NPP (also known as Leningrad-II 3&4). The permit is valid for five years, until November 2028.
“We have received an important document that gives us the right to start one of the key stages of construction and installation work at the facilities of unit 7. We will start with the development of a pit for the nuclear island in order to embark on the first key operation in the spring of next year – concreting the foundation slab for the reactor building," said Vladimir Pereguda, director of Leningrad NPP.
In December 2022, the expert commission of the State Ecological Expertise issued a positive opinion on the materials for substantiating the licence for the construction of VVER- units 7&8, In early May Leningrad NPP, received a positive conclusion from the State Expertise on the project for the construction of the new units.
These documents confirmed that the design of the second stage with VVER-1200 reactors of the Leningrad NPP complies with environmental requirements and legislation in the field of environmental protection, the requirements of technical regulations in the field of nuclear, environmental and industrial safety, sanitary and epidemiological requirements, etc. Until the end of the current In 2009, the customer plans to obtain licences for the construction of nuclear installations at two new power units.
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 (LNPP-II 3&4) will replace the original RBMK units 3&4.
