Rosatom, PUBLISHED 18.12.2024

The reactor pressure vessel has been installed in the design position at the construction site of Xudapu NPP Unit 4 (China), which is being built with participation of Rosatom enterprises. The operation was carried out under the supervision of representatives of Rosatom Engineering Division.

"Xudapu NPP project is a vivid example of cooperation between Russia and China in the field of advanced technologies. Our partnership has been going on for decades, and the power units constructed under the Russian design demonstrate long-term efficient and trouble-free operation. Our joint history is continuing: Rosatom, being the leading technological corporation of Russia, jointly with the Chinese partners, is successfully implementing the project of construction of the newest NPP Gen III+ power units ", said Alexey Bannik, Vice President of Atomstroyexport JSC (Engineering Division of Rosatom) for Projects in China and Prospective Projects.

Earlier, works were carried out at Unit 4 of Xudapu NPP in advance of the installation of the reactor pressure vessel. In particular, the first large-sized equipment - the core catcher, was installed, operation for one-stage lifting of the dome to the building was completed, the polar crane was installed, with which the reactor vessel was lifted and placed in the design position.


VVER-1200 reactor is a cylindrical vessel with an elliptical bottom, inside which there is the core and the internals. The length of the equipment is 13 meters, the diameter is 4.5 meters, and the weight is 320 tons.

Xudapu NPP is a new project of cooperation between Russia and China in the field of nuclear power. It is located in the city of Huludao (Liaoning province). In 2019, a number of contracts were signed, including the general contract for construction of Xudapu NPP Units 3 and 4 with VVER-1200 reactors and the contract for nuclear fuel supply. In accordance with the contract, the Russian Party will design the nuclear island, supply the key equipment of the nuclear island for both power units and render services for designer supervision, installation supervision and adjustment supervision of the supplied equipment. The commissioning of the units is scheduled for 2027-2028.

The strategic package of the documents determining the major areas 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 the Tianwan NPP and Units 3 and 4 of Xudapu NPP.

From the Russian party, the contract was signed by the Engineering Division of State Atomic Energy Corporation Rosatom, and on the Chinese party - by CNNC companies. According to the document, the Russian party will design the nuclear island of the NPP and supply the key equipment of the nuclear island for both units.
