The Taishan Nuclear Power Plant (Chinese: 台山核电站; pinyin: Táishān Hédiànzhàn) is under construction in Chixizhen, Taishan, Guangdong province, China.[1] The plant features two of Areva's European Pressurized Reactor (EPR). It was planned to go online in 2013 and to be the third site to house EPR units. However, the start of operation has been postponed to late 2018. Also, more severe delays in other EPR construction sites mean that Taishan will probably be the first nuclear power plant with an operational EPR unit. The project is owned by Guangdong Taishan Nuclear Power Joint Venture Company Limited (TNPC), which is 70% owned by China Guangdong Nuclear Power Group (CGNPC) and 30% by Électricité de France (EDF).

Each generator delivers 1750 MWe (Nameplate capacity); generators of that size are the largest single-piece electrical generators. The 495 tonne generator stator is built by Dongfang Electric. Of the 1750 MWe gross delivered, around 90 MWe will be used by plant systems such as the large pumps that circulate cooling water, leaving 1660 MWe net for supply to the grid.[2]

Construction[edit]

On August 26, 2008, excavation work began.[3] The first concrete for the first unit was poured in October 2009.[4] Construction of each unit was planned to take 46 months, significantly faster and cheaper than the first two EPRs in Finland and France.[5] These plans have proved elusive as start up has been repeatedly delayed. In February 2017 after 88 months of construction, CGNPC announced that completion of the reactors would be delayed until the second half of 2017 and the first half of 2018.[6]

In spite of this announcement, completion of the plant continues to be delayed. In December 2017, Hong Kong media reported that a boiler had cracked during testing, and that welding on the component was considered "problematic". Neither the nuclear plant's operators nor the manufacturer of the affected component responded to the news agency's request for comment.[7]

In January 2018 commissioning was rescheduled, with commercial operation now expected in 2018 and 2019.[8]

On April 9, 2018, the Official Letter of Approving the Initial Fuel Loading of the first unit of the Taishan Nuclear Power Plant was issued by the National Nuclear Safety Administration (NNSA). Taishan Unit 1 began fuel loading at 18:18 on April 10, marking the beginning of fuel loading of the first reactor using the third-generation nuclear power technology EPR.[9]

First criticality was achieved at Taishan Unit 1 on June 6, 2018.[10] On June 29, 2018, Taishan 1 was connected to the grid,[11][12] with full power operation achieved on August 11 of the same year.[13] Total construction time was thus 104 months, more than twice as long as the originally planned 46 months.
