Recently, the world's first high-temperature gas-cooled reactor demonstration project settled in Rongcheng, Shandong has completed all the tasks in the charging preparation stage, and is about to enter the nuclear test operation. A critical step is taken towards the commissioning of power generation.

Shidao Bay Nuclear Power Plant, commonly known as Shidaowan, is a nuclear power plant in Shandong province, China. The site is located near the Xiqianjia village in Ningjin subdistrict, Rongcheng, Weihai, Shandong. The plant is located about 23 kilometres south of Rongcheng City, 14 kilometres northwest of Shidao, and 68 kilometres southeast of Weihai City.

The plant will have the first fourth-generation nuclear reactors in the world: the HTR-PM, a high-temperature gas-cooled reactor (HTGR) concept. The plant will ultimately have ten 210 MW units of this type. Each unit is made of two HTR-PM reactors driving a single 210 MW steam turbine.

The plant does also host the construction of two 1,500 MW CAP1400 pressurized water reactors, a design based on the AP1000 jointly developed by Westinghouse and China's State Nuclear Power Technology Corporation.

Shidao Bay nuclear power plant is a joint venture by China Huaneng Group, China Nuclear Engineering & Construction Group, and Tsinghua University. The total investment of 100 billion yuan and the 20-year construction plan makes it China's largest planned nuclear project.
