Dome of reactor building of Xudapu NPP Unit 3 in China was raised and installed in one stage


The dome of the reactor building of Unit 3 of Xudapu NPP that is being constructed with the participation of Rosatom State Corporation Engineering Division, has been lifted and installed on the reactor building in one stage. Previously, installation was carried out in two stages during construction of NPPs under Russian designs.

“A unique process operation has been completed at Xudapu NPP, which made it possible to optimize the process and lift the dome 188 days earlier than the deadline envisaged by the contract. The 740-ton dome that had been fully assembled on the ground, was raised by the crane and installed on the reactor building”, said Alexey Bannik, Vice President for Projects in China and Prospective Projects of ASE JSC. “I am confident that the efficient joint work of the Russian and the Chinese specialists will allow to implement Xudapu NPP strictly on time”.

The next stage after the dome installation will be concreting inside and outside the dome part of the reactor building, the construction of the trestle and installation of large-size equipment which will be performed with the polar crane installed in mid-July.

 For reference:

Xudapu NPP is a new project of cooperation between Russia and China in the field of nuclear energy, located in the city of Huludao (Liaoning Province). In 2019, a number of contracts were signed, including the General Contract for the construction of Units 3 and 4 of Xudapu NPP with VVER-1200 reactors, as well as a contract for nuclear fuel supply. In accordance with the contracts, the Russian party will design the “nuclear island” of the plant, supply key equipment for the nuclear island for both power units, provide designer supervision, installation supervision and adjustment supervision services for the equipment supplied. Commissioning of the units is scheduled for 2027-2028.

The strategic package of documents determining the major guidelines for the Russian-Chinese cooperation in the nuclear industry for the next decades, was signed in June 2018. In particular, it was decided to build four new power units with Gen III+ VVER-1200 reactors, namely Units 7 and 8 of Tianwan NPP and Units 3 and 4 of Xudapu NPP.

From the Russian side, the contract was signed by the Rosatom State Corporation Engineering Division, and from the Chinese side - by CNNC companies. In accordance with the documents, the Russian side will design the NPP nuclear island and supply the key equipment of the nuclear island for both units.

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.

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.
