In the reactor building of Kursk NPP-2 power unit No. 1 (with the Rosatom State Corporation Engineering Division being its general designer and general contractor), a circular electric overhead travelling crane (polar crane) of 390t design load capacity has been put into operation.
This is one of the key machines of the reactor compartment, belonging to the first (highest possible) safety class of the NPP equipment.
The design of the polar crane allows for transport operations to be performed at any point in the central hall of the reactor building, i.e. the trolley travels along the bridge (its span being 41.5 meters), the crane itself moves along a circular rail track mounted at the top of the cylindrical part of the building. The total weight of all crane elements is about 440 tons. As part of preparation for the certification, static tests of the main lifting machine were carried out with a simulated load of 432 tons.
The installation of the crane and the related pre-commissioning works were performed by the staff of Energospetsmontazh JSC MSU-5 Branch (belonging within the Rosatom Engineering Division).
“The launch of the polar crane is a landmark in getting prepared for the key happening of the year which is expected to take place at the Kursk NPP-2 construction site, namely installing the power unit reactor vessel in the design position”, Oleg Shperle, Vice-President-Director of the Kurks NPP-2 Construction Project pointed out.
After the power unit is put into operation, the polar crane will be operated to perform a wide range of tasks at all stages of the NPP life cycle, in particular, it will be used to handle transport and technological operations related to the power unit operation and the reactor plant equipment, for example, nuclear fuel loading and takeout.

For reference:
Rosatom State Corporation Engineering Division unites the leading companies of the nuclear industry, namely: Atomstroyexport JSC (Moscow, Nizhny Novgorod, branches in Russia and abroad), Joint Design Institute - Atomenergoproekt JSC (Moscow, Nizhny Novgorod, St. Petersburg branches - design institutes, branches in Russia and abroad, R&D branches) and subsidiary construction organizations.
The Engineering Division ranks first in the world by the order portfolio and the number of NPPs constructed simultaneously across the world.
About 80% of the Division’s revenues originate from foreign projects.
The Engineering Division implements construction projects for high-power NPPs in Russia and across the world, renders a full range of EPC, EP, and EPC(M) services including project management and design activities, and develops Multi-D technologies for the management of complex engineering facilities. The Division relies on the achievements of the Russian nuclear industry and innovative state-of-the-art technologies.
We construct reliable and safe NPPs with Gen III+ VVER reactors that are in line with all international requirements and recommendations.
