Kay equipment has been delivered to China’s Tianwan NPP in Jiangsu province including two steam generators, the reactor pressure vessel (RPV) and pressuriser. The consignment left Rosatom’s Atommash production site in Volgodonsk on 12 June and arrived at Yingkou Port in China after 62 days at sea. The shipment was then transported to the Tianwan site’s wharf by two deep-deck ships.
China National Nuclear Corporation (CNNC) subsidiary China Nuclear Power Engineering Company (CNPEC) said the Tianwan Project Department “organised all participating units to work together efficiently and successfully completed a series of tasks such as unloading and hoisting, short-distance transportation, equipment self-unloading, and temporary storage,”
In 2018, Russia and China signed four agreements, including for the construction of two VVER-1200 reactors for Tianwan units 7&8. Construction of unit 7 began in May 2021and of unit 8 in February 2022. The units are scheduled to be commissioned in 2026-2027. Tianwan 1-4, with VVER-1000 reactors ,commissioned between 2007 and 2018, are already in operation. Units 5&6 with Chinese ACPR-1000s were commissioned in 2020 and 2021.
The RPV and four steam generators for Tianwan unit 7 were shipped in 2023, as well as two of the four steam generators for unit 8. “The comprehensive entry of the main equipment of unit 8, such as steam generators, pressure vessels, and stabilisers, laid a solid foundation for the construction of the key path of the installation of the main equipment of unit 8, marking another solid step forward in the construction of Tianwan units 7 and 8,” CNPEC added. Earlier in August, the Petrozavodskmash plant (part of Rosatom’s Mechanical Engineering Division) began shipping main circulation pump casings for Tainwan 8.
Tianwan NPP is owned and operated by the Jiangsu Nuclear Power Corporation, whose shareholders are CNNC (50%), China Power Investment Corporation (30%) and Jiangsu Guoxin Group (20%).
