Professionals of the Volgodonsk Branch of JSC “AEM-technology” (a part of the machine-building division of the ROSATOM state corporation - “Atomenergomash”) have started manufacturing essential equipment for Xudapu NPS, unit No.3.
According to the contract, JSC “AEM-technology” is to manufacture and deliver two Generation 3+ VVER-1200 Reactor facilities, two sets of Steam generators, Reactor coolant pump set and Main circulation piping bodies and two Pressurizers. The total weight of the items will be about 6,000 tons.
At present, the blanks of the Steam Generator and Reactor vessel shells have passed the incoming inspection, and the production has been started. Machining of each 92-ton Shell of the nozzle area of the Reactor vessel is carried out for 15 days. At the same time, preparation for anti-corrosive overlaying of the Shell of the Reactor core is performed. Machining of the Steam Generator shells, each weighing 37 tons, is carried out for 6 days. Upon the completion of machining of 16 blanks, the professionals will start manufacturing the Steam Generator vessels.
The Director General of JSC “AEM-technology”, Igor Kotov states that Xudapu NPP is the second project in the People’s Republic of China, for which “AEM-technology” manufactures equipment.
“We already have an extensive experience of meaningful cooperation with Chinese colleagues, and our equipment has a good account at the Chinese market. I am confident that our activities on implementation of the new project will fully meet the expectations of our partners and will once again confirm the high competencies of the Russian nuclear power engineering industry,” he emphasized.
The Reactor is equipment of the first safety class. It is a vertical cylindrical vessel with an elliptical Head, inside of which there are the Internals that confine the Core. At the top, the Reactor is tightly closed with the Cover with drives of mechanisms and Reactor regulating and protecting components installed on it, and Nozzles for outputting cables of the in-reactor control sensors.
The Steam Generator is a heat exchanger that is part of a steam-generating unit. It is an item of the first safety class. The diameter of the item is more than 4 meters, its length is about 14 meters, its weight is 340 tons. Four Steam Generators are manufactured for each NPP power unit.
Xudapu NPS is located in Liaoning Province, PRC. Power units No. 3 and No. 4 are constructed according to the “NPP-2006” project and comply with the modern IAEA safety requirements. The design and construction of the facility is carried out by the Engineering division of the ROSATOM state corporation
