The pressurizers of Fuqing Unit 6, a Hualong one (HPR1000) demonstration project, passed inspection on Aug 14, signifying that research and production of all pressurizers for the four Hualong one units, both in China and abroad, have been completed.
The Hualong one pressurizers are key pieces of equipment for the reactor coolant system. Operating in a harsh environment, the system needs to be able to withstand frequent thermal shocks. The pressurizers play a key role in ensuring the safety of the primary coolant circuit.
The Hualong one pressurizers make use of many new technologies, raising the standard for China-made pressurizers for nuclear reactors.
The pressurizer was designed by CNNC's Nuclear Power Institute of China, while CNNC's China Nuclear Power Engineering Co and Dongfang Electric (Guangzhou) Heavy Machine Co Ltd were responsible for procurement and production, respectively.
