Leningrad NPP: the turbine generator stator of the power unit No 2 with VVER-1200 under construction was placed at its proper location

On 29 December, 2017 at Leningrad NPP-2 power unit No 2 one of the key events of the year was carried out – the turbine generator stator was placed at its proper location.

This is the most large-sized and the heaviest equipment of the turbine island; its main function is to translate the mechanical energy of rotation into electric one.

With the help of electric overhead travelling crane of turbine building the stator with weight of 440 tons and with the height of 15 m was lifted from 0.00 m mark, carried through transport gateway to +16.00 mark and put at its design location. The transport and technological operation was carried out without remarks.

“Turbine generator stator was placed precisely and safely. The long term and thorough preparation of all the participants of the operation – including the assembly personnel – and scrutinous elaboration of the adopted technical decisions were the key to success. In addition, we founded upon the experience we received during the assembly of the similar equipment at the first power unit. We frequently use the crane involved in this operation, including the operations with the nominal load of 440 tons”, the Deputy Head of Centralized Repair Shop of the Leningrad NPP under construction Andrey Kuznetsov said.
The positioning of the turbine generator stator at its proper location will allow to proceed to the setting of turbo generator shafting the next year.

The Leningrad NPP is an affiliate company for Rosenergoatom Concern OJSC. The plant is based in the city of Sosnovy Bor, 40 km to the west from Saint Petersburg at the Gulf of Finland shore. The Leningrad NPP is the first Russian nuclear power plant having RBMK-1000 reactors (uranium-graphite channel-type thermal neutron reactors). The NPP exploits 4 power blocks with the electric capacity of 1000 megawatt each. Also, pursuant to the NPP-2006 project, 1,2 VVER-1200 power blocks included into The State Atomic Energy Corporation ROSATOM long-term plan are being constructed. Rosenergoatom Concern OJSC is the owner and developer of the project. Holding TITAN-2 is the primary contractor. ATOMPROEKT is the general designer.
