Three steam generators for unit 4 of the Xudabao NPP in Liaoning Province have been shipped from Rosatom’s machine-building plant in Volgodonsk. The total weight of the cargo is 1,000 tonnes. Each steam generator for plants with VVER-1200 reactors weighs 340 tonnes and is four metres in diameter with a length of about 14 metres.
Delivery to the NPP construction site will be carried out using a combination of road, river and sea transport. The first batch of key equipment for Xudabao 4 – the VVER-1200 reactor vessel and steam generator – was shipped in mid-August.
“The enterprises of the Mechanical Engineering Division of Rosatom proceeding rapidly with production of equipment for the NPPs that Rosatom is building abroad,” said Igor Kotov, head the Mechanical Engineering Division. Not a month goes by without products being shipped from our sites in Volgodonsk, St Petersburg and Petrozavodsk for the reactors and turbine rooms of future NPPs. Regular shipments are the result of the coordinated work of our nuclear engineers and the high quality of Russian nuclear technologies.”
Work is currently continuing at the Rosatom machine-building sites in Petrozavodsk and St Petersburg on the production of a pressure compensator, the main circulation pipeline and the main circulation pump unit for the Xudabao NPP. The work is proceeding strictly according to schedule and in line with the contract terms.
The Xudabao project was originally expected to comprise six CAP1000 reactors – the Chinese version of the Westinghouse AP1000 – with units 1 and 2 in the first phase. However, plans changed, and two VVER-1200 reactors were designated for Xudabao 3&4. Two CAP1000 reactors are planned for Xudabao 1&2. Construction of unit 1 began in November 2023.
At Xudabao 3&4 Rosatom is designing the nuclear island, supplying key equipment, as well as providing field supervision, installation supervision, and commissioning services for the supplied equipment. The balance of plant will be supplied by China. Construction of Xudabao 3 began in July 2021, and unit 4 in May 2022. The commissioning of the units is scheduled for 2027-2028.
