A two-unit demonstration plant was initially planned for construction by CNNC New Energy Corporation – a joint venture of CNNC (51%) and China Guodian Corp – in Putian county, in south Fujian province. However, in early 2017, the site for the first ACP100 units was changed to Changjiang, with a larger reactor to be built at Putian. It will be sited to the north-west side of the Changjiang NPP, where two CNP600 PWRs are operating, with two Hualong One units planned, according to China's Ministry of Environment. In 2016, China announced plans to build a demonstration floating nuclear power plant based on the ACP100S variant of the CNNC design.
