Shidao Bay Nuclear Power Plant
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 site is located near the Xiqianjia village in Ningjin subdistrict, Rongcheng, Weihai, Shandong. The plant is located about 23 kilometres (14 mi) south of Rongcheng City, 14 kilometres (8.7 mi) northwest of Shidao, and 68 kilometres (42 mi) southeast of Weihai City.
The plant has the first fourth-generation nuclear reactors in the world: the HTR-PM, a high-temperature gas-cooled reactor (HTGR) concept (36°58′45″N 122°31′50″E / 36.97917°N 122.53056°E). The plant will ultimately have ten 210 MWe (megawatts electrical) units of this type. Each unit is made of two HTR-PM reactors driving a single 210 MWe steam turbine.
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), a design based on the AP1000 jointly developed by Westinghouse and China's State Nuclear Power Technology Corporation (SNPTC).
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 (US$15.7 billion) and the 20-year construction plan makes it one of China's large nuclear projects.
In 2005, China announced its intention to scale up the HTR-10 experimental reactor for commercial power generation. 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. In 2009, it was planned to be finished in 2013. Construction finally began at the end of 2012, with the pouring of concrete basemat occurring in April 2014. The vessel was installed in 2016. It was expected to begin operating around 2017, later postponed to 2018. The pressure vessel head was installed in December 2017. Cold testing was completed in November 2020. Hot functional testing of the reactors began in January 2021, and operational start up is planned for late 2021. The first reactor went critical, marking the first criticality of a generation IV commercial nuclear power plant, in September 2021. Reactor two achieved first criticality in November 2021. Reactor one was connected to the state power grid and began producing power in December 2021 The HTR-PM project demonstrated it had reached "initial full power" in December 2022. The HTR-PM project finally entered commercial operation in December 2023. An updated larger power plant, HTR-PM600, is planned with a capacity of 600 MWe using six HTR-PM reactor units.
In July 2024, first concrete was poured for Shidaowan 1, the first of four Hualong One reactors. In May 2025, first concrete was poured for Shidaowan 2.
In November 2006, State Power Investment Corporation (SPIC) introduced the AP1000, a third-generation pressurized water reactor design, from the U.S. company Westinghouse Electric Corporation.[citation needed] Since then China built four AP1000 units, two in the Sanmen Nuclear Power Station, and another two in the Haiyang Nuclear Power Plant.
