China Nuclear Industry Zhongyuan Company is responsible for the erection of heavy pieces.

The Haiyang Nuclear Power Plant is located at Liugezhuang Town in Haiyang City, in northern China's Shandong province. The power plant has a total planned capacity of six 1,000-megawatt (MW) nuclear power units, with space reserved for future expansion. Shandong Nuclear Power Company Limited (Yantai, Shandong), a joint venture under the control of China Power Investment Corporation (Beijing) (40%), with the participation of China Nuclear Power Corporation (Beijing) (20%), China Guodian Corporation (Beijing) (20%), China Huaneng Group (Beijing) (5%) and two other local power investors from Shandong and Yantai are responsible for the development and future operation of the project.
