The fourth nuclear power unit on the second phase of the Zhangzhou nuclear power project in Zhangzhou, Southeast China's Fujian province, recently started the pouring of its first batch of concrete, marking the full-scale construction of the nuclear power plant installed with Hualong One technology.

According to China National Nuclear Corporation (CNNC), Hualong One is a domestically designed third-generation nuclear reactor that has met the strictest safety standards in the world and has been one of China's major sci-tech achievements in the nuclear power sector. So far, it has had the largest number of operational and under-construction nuclear power reactors installed with the third-generation nuclear power technology and become a typical symbol for Chinese nuclear power technology to compete with its global counterparts.

Each Hualong One nuclear reactor is expected to generate up to 10 billion kilowatt-hours of electricity per year, which can meet the annual production demand and domestic electricity demand of 1 million people in moderately developed countries. It is equivalent to the reduction of 3.12 million tonnes of standard coal consumption and 8.16 million tonnes of carbon dioxide emissions as well as the plantation of over 70 million trees.

Zhangzhou Nuclear Power is the starting point for the massive construction of Hualong One nuclear reactors, with a total of four units now under construction. The Unit 1 is expected to start electricity generation by the end of 2024. The Unit 2 is going ahead with relevant necessary work of its pre-cold testing. The Unit 3 started its construction in this February. The preliminary work for Units 5 and 6 has been undertaken orderly.
