The Taishan nuclear power plant ( Chinese  台山 核电站 , Pinyin Táishàn Hédiànzhàn ) with two EPR reactors is located near Yaogu in the Chinese province of Guangdong on the coast of the South China Sea approx. 42 km southeast of the city of Taishan . The two EPR blocks went into operation in 2018 and 2019.

history

Originally, six CPR reactors were planned for the Taishan site. But since Areva NP made a more attractive offer, it was decided to build two EPRs ( marketed in China as Evolutionary Power Reactors ). Both reactors have a nominal output of 1750 MW each and a net output of 1660 MW each. These EPR could form a basis for future reactors of this construction line in China. The turbines are supplied by Alstom and Dongfang .

According to the original plans, the costs of the entire project, including fuel costs, should amount to around eight billion euros. The reactors themselves should cost 3.5 billion euros, including the turbines 300 million euros. On November 26, 2007, the contract for the construction of the reactors was signed between the Guangdong Nuclear Power Joint Venture Company and Areva. The China Guangdong Nuclear Power Company has signed a contract with Areva to enable the production of the fuel in China. In return, Areva got 35% of UraMin's production . The first two reactor loads and the first 17 fuel assemblies for the fuel change will, however, be manufactured in France.

In August 2008 there was the first construction work on the site. Construction of the first reactor officially began on October 28, 2009, the second followed on April 15, 2010. The owner and operator is the 'Taishan Nuclear Power Joint Venture Company', which is 30% owned by the French electricity company Électricité de France and 70% owned by China's China Guangdong Nuclear Power Group (CGNPC).

Delays and cost overruns in construction

In 2012 it was assumed that Unit 1 could be completed in 2013 and Unit 2 in 2014. In summer 2014, the target completion dates were 2015 and 2016; these dates have since been repeatedly postponed. The reactors were finally commissioned in 2018 and 2019, as planned in 2018. This meant that they were completed faster than the EPRs that had started earlier in Finland and France.

In January 2016, the cold run of the reactor and auxiliary system, in which the integrity of the lines was checked, was successfully completed in Unit 1. In March 2016, the construction of Unit 1 was completed and the test phase for the start of operations began. Commissioning was planned for the second half of 2017. During function tests, a degasser burst , which then has to be replaced. According to media reports, it is an air separator about 46 m long and about 4.5 m in diameter. The poor quality of the component is said to have been known since 2012.

In January 2018, both reactors were both behind schedule and above budget. While the operator had originally estimated costs of 14 yuan per watt of installed capacity, the actual costs of the reactors were already estimated at around 22-23 yuan per watt (2.7 to 2.8 euros / watt) in 2017. In total, the reactors have a gross output of 3500 megawatts.

Installation

On June 6, 2018, Block 1 reached its first criticality, on June 29, 2018 it was connected to the grid, and on December 13, 2018, it went into commercial operation.

Block 2 reached the first criticality on May 28, 2019, it was connected to the grid on June 23, 2019, and it went into commercial operation on September 7, 2019.
