China / Outer Dome Concreting Complete At Zhangzhou-2 Nuclear Plant

China has completed pouring concrete over the outer dome of the containment building for the Zhangzhou-2 nuclear power plant under construction in Fujian province, southeastern China.

According to the China Nuclear Energy Association (CNEA), the move marked the completion of the main structure and paves the way for cold functional testing at the plant.

Zhangzhou-2 is a domestic 1,126-MW HPR1000, or Hualong One, pressurised water reactor (PWR).

Construction began in September 2020 and the unit is scheduled for commercial operation in 2025, according to earlier reports.

There are three other Hualong One PWRs under construction and commissioning at the site. Last month, China National Nuclear Corporation (CNNC) said it started fuel loading at Zhangzhou-1.

Construction of Zhangzhou-3 and -4 began in Feb 2024 and Sep 2024.

The Hualong One is an indigenous, three-loop pressurised water reactor. It incorporates elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactor designs.

It is Beijing’s domestic flagship reactor technology, with 17 of the 28 reactor units under construction in China being of the Hualong One design. There are also two Hualong One plants in operation outside China, both in Pakistan at the Kanupp nuclear station, also known as Karachi.
