The first overhead electric crane with a lifting capacity of 15 tons has been installed on the crane tracks in the turbine building of unit 1 of Russia’s Kursk-II NPP, the plant reported on 16 February. Installation will now begin of the mechanical and electrical parts of the crane. Two more bridge cranes will be installed in the turbine building - with a lifting capacity of 30 tons and 290 tons. In the first half of this year, it is planned to complete installation and conduct acceptance tests for all three cranes.
“During the construction period, the cranes will be used to erect equipment and move heavy loads in the turbine hall. With their help, the elements of the turbine unit, the separator-steam superheater, high pressure heaters will be mounted,” explained Alexey Buldygin, head of the Capital Construction Department. “And during operation, cranes are needed to organise repair work and service the main and auxiliary equipment of the turbine building. The cranes are provided for the entire service life of the unit, that is, for 60 years.”
The three overhead cranes will operate at different levels and represent one complete system. The electronic crane control system excludes the possibility of collision. According to the plan, all three cranes are to be commissioned in July 2021. “The general contractor, represented by the Kursk branch of ASE, is working in strict accordance with the schedule,” said Oleg Shperle, Vice President, Director of the Kursk NPP-II project. "Our top priority is safety and quality."
Earlier in February, specialists from Titan-2 completed concreting of the cooling tower ring foundation at Kursk-II. During the work, 6,000 cubic metres of concrete were laid. Two evaporative cooling towers are being built at the site. Titan-2 is building the cooling tower for unit 2.
Backfilling of the inner part of the future cooling tower with sand is now in progress. Then the reinforcement and concreting of the drainage basin slab will begin, and after that the specialists will proceed with the installation of the inclined colonnade and the construction of the cooling tower shell.
