ROSATOM Starts Manufacturing Equipment for Xudapu NPP of China
ROSATOM machine-building division AEM Technology’s Volgodonsk branch has started manufacturing essential equipment for Xudapu NPP Unit 3. AEM-technology will manufacture and deliver two Generation III+ VVER-1200 reactor facilities, two sets of steam generators, reactor coolant pump set, main circulation piping bodies and two pressurizers. The total weight of the items will be about 6,000 tons. Currently, 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, manufacturing of the steam generator vessels will commence.
The reactor is equipment of the first safety class. It is a vertical cylindrical vessel with an elliptical head, inside of which there are 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, and its weight is 340 tons. Four steam generators are manufactured for each NPP power unit.
Xudapu NPP is located in Liaoning Province, PRC. Units 3&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 ROSATOM engineering division
