The demonstration ACP100 plant would be located on the north-west side of the existing Changjiang nuclear power plant, according to a March 2019 announcement from China's Ministry of Environment. The site is already home to two operating CNP600 PWRs, while the construction of the first of two Hualong One units began in March this year. Both those units are due to enter commercial operation by the end of 2026.

In 2021, China approved the construction of five nuclear power units, with total installed capacity of 4.9 GW, roughly 10% of the country's total. The five reactors approved include four regular nuclear units – number 7 and number 8 at Tianwan nuclear power plant in eastern Jiangsu province, and number 3 and number 4 in Xudapu in northeastern Liaoning province.

All four will use Russian-made VVER-1200 technology and have individual capacity of 1.2 gigawatts (GW).
