Polar crane beams have been installed in the design position at Tianwan NPS power unit No. 7 constructed in China with participation of Rosatom State Corporation Engineering Division.
This event marks the beginning of installation of the polar crane whose hoisting capacity is 360 tons. The installation is to be completed in May 2023. Before the construction of the power unit is completed, the polar crane will perform hoisting and conveying operations to ensure installation of the large-sized equipment of the reactor building containment (such as the reactor vessel, steam generators, pressurizer); consequently, during the NPS operation, the crane will be used to perform handling and process operations related to operation of the power unit and the reactor plant equipment.
“The two great powers continue to implement their plans related to the development of the peaceful atom. The Tianwan NPS is a shining example of our joint work to solve this problem. The construction of the Russian VVER-1200 power units is proceeding exactly on schedule. We will continue developing our successful cooperation in the field of nuclear energy,” said Alexey Bannik, ASE JSC Vice President for Projects in China and Prospective Projects.
After the installation of the polar crane is completed, installation of the inner containment dome of the reactor building will begin.
For reference:
Tianwan NPS is the largest project of economic cooperation between Russia and China. Currently, two power units are being built according to the Russian VVER-1200 design. The earlier four units of the Russian VVER-1000 design are successfully operating and supplying millions of kilowatts of energy to the country's power grid. June 8, 2018 is the date when the Intergovernmental protocol and the frame contract for construction of TNPS Units Nos. 7&8 with VVER-1200 reactors were signed in Beijing. From the Russian side, the contract was signed by the Rosatom State Corporation Engineering Division, and from the Chinese side, it was signed by CNNC companies. In accordance with these documents, the Russian side has designed the NPP nuclear island and it will supply the key nuclear island equipment for both units. The following executive contracts were signed as well, such as the basic design contract for Units Nos. 7&8; the general contract for power units Nos. 7&8. In accordance with the signed contracts, the Engineering Division is involved in designing and delivery of nuclear island documentation and equipment and provision of associated services (such as designer supervision, installation supervision, adjustment supervision). The works on construction of power units Nos. 7&8 started on May 19, 2021.
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, 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.
Russia continues mutually beneficial cooperation with friendly countries. The implementation of major energy sector projects is underway. Rosatom's work under the projects in China is an example of meaningful partnership that opens up new opportunities in the field of low-carbon generation.
