The main technological equipment of the reactor building is being installed at Leningrad NPP power unit No 2 under construction: the two main circulation pump casings are being assembled in the proper location. The works were carried out using a heavy crawler crane Liebherr LR 11350.


The main circulation pumps are designed to create coolant recirculation in the primary circuit of the power unit and to remove heat from the reactor core. In the period of operation, they will pump at least 80,000 cubic meters of coolant per hour.
ТThe experts of the contractor company had made preliminary pre-assembly works of the casings near the power unit. The total weight of each assembled structure was more than 65 tons; they were then placed to the proper location. The use of such a technological solution allowed to improve the assembly quality, reducing labor costs, and optimizing the assembly time. At the next stage the remaining elements will be put together. They include pull-out parts, electric motors and auxiliary pump systemsУ, the Deputy Head of the Reactor Department of Leningrad NPP under construction Aleksey Mochalov said.
           
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.
