The Hualong One (Chinese: 华龙一号; pinyin: Huálóng yī hào; lit. 'China Dragon №1') is a Chinese Generation III[1] pressurized water nuclear reactor jointly developed by the China General Nuclear Power Group (CGN) and the China National Nuclear Corporation (CNNC). The CGN version, and its derived export version, is called HPR1000.[2] It is commonly mistakenly referred to in media as the "ACPR1000" and "ACP1000", which are in fact earlier reactors design programs by CGN and CNNC.
Unit 5 of the Fuqing Nuclear Power Plant was the first Hualong One to enter commercial service on 30 January 2021.[1][3][4]
