Equipment delivery begins for Leningrad 7&8

6 December 2023

The first large-sized equipment – three giant tower cranes with a lifting capacity of 50 tonnes – has been delivered to the construction site of the Leningrad NPP for units 7&8 (also referred to as units 3&4 of Leningrad-II NPP). Some 60 heavy vehicles were used to transport the cranes – each 80 metres high and weighing 535 tonnes. They will be used to support installation of key components for the two VVER-1200 reactors.

“Preparatory work is underway at the construction site of the Leningrad NPP. Builders have already developed a pit for the nuclear island for unit 7 and are continuing to construct a pit for its turbine island,” said Evgeniy Milushkin, Deputy Director for Capital Construction and Head of the Capital Construction Department of Leningrad-II.

“After receiving the key document – a construction licence – before the end of the year, work at the site will begin in full force. The delivery of the first batch of equipment - tower cranes, sensors for the system for monitoring the stress-strain state of the containment, special sewage ladders will be delivered in December. The first batch of reinforcement weighing 3,500 tonnes has been delivered to the construction base of general contracting organisation TITAN-2. It will be used to reinforce the foundation slabs of the new power units. In total, Leningrad NPP will require about 300,000 tonnes of reinforcement.”

First concrete for the foundation slab under the reactor building of unit 7 is planned for March 2024. Currently, two new concrete plants are being installed in addition to the two existing ones. Together they will produce more than 1m cubic metres of concrete – for the two new units.
