Shidao Bay Nuclear Power Plant (simplified Chinese: 石岛湾核电站; traditional Chinese: 石島灣核電廠; pinyin: Shídǎo wān hédiàn chǎng), commonly known as Shidaowan, is a nuclear power plant in Shandong province, China.

The plant also hosts the construction of two 1500 MWe CAP1400 pressurized water reactors (36°57′56″N 122°31′12″E / 36.96556°N 122.52000°E / 36.96556; 122.52000), a design based on the AP1000[4] jointly developed by Westinghouse and China's State Nuclear Power Technology Corporation (SNPTC).

The first two 250-MWt High-Temperature Reactor-Pebble-bed Modules (HTR-PM) will be installed at Shidao Bay, and together drive a steam turbine generating 200 MWe.

Originally to be started in 2011, the project was postponed after the Fukushima Daiichi nuclear disaster in Japan in March 2011.

China has been researching and developing its own version of the AP1000, the more powerful CAP1400, also referred to as Guohe One (Guo He One, Chinese: 国和; pinyin: guó hé, i.e. unity of the country).

[22] In May 2016, the CAP1400 design has successfully passed the International Atomic Energy Agency's (IAEA) Generic Reactor Safety Review.

According to SPIC, the company is building two CAP1400 reactors in a demonstration project located in the Shidao Bay nuclear plant.

The pressure vessel is the core equipment of the reactor and has a total weight of about 487 tons and a design life of 60 years.
