Tianwan Nuclear Power Plant ( Chinese:田湾核电站 )is located in Tianwan District, Lianyungang District, 30 kilometers away from Yungang City in Jiangsu Province on the east coast of China.
The installed capacity of this nuclear power plant is 5,070 MW. Construction started on October 20, 1999, power generation began on May 12, 2006, and commercial operation began on May 17, 2007.
The power plant is developed jointly by China and Russia. The Chinese party is Jiangsu Nuclear Power Company, and the major shareholder of this company is China National Nuclear Corporation (CNNC). The Russian side is Atomstroyexport (ASE), which is controlled by the Russian nuclear industry company Rosatom.
The four reactors of the nuclear power plant have a rated power of 1,000 MW (built by ASE), the other two are constructed by CNNC with a rated power of 1,000 MW, and the other two are approved by ASE with a rated capacity of 1,200 MW. Device.
If all eight units of the installation plan are completed, Tianwan will become the world’s largest nuclear power plant with a total installed capacity of approximately 8,100 MW, surpassing South Korea’s Kori Nuclear Power Plant and Japan’s Kashiwazaki-Kariwa Nuclear Power Plant.
Unit 1 and 2
The construction of the first reactor began on October 20, 1999, and the construction of the second reactor began on October 20, 2000. The construction of the second reactor was completed in May 2007, and commercial operation began in August. This is the first time that China and Russia have cooperated on a nuclear power project.
Units 3 and 4
Construction of Unit 3 began on December 27, 2012. The construction of Unit 4 was carried out on September 27, 2013.
The construction of Unit 3 was completed and put into operation in late December 2017, and commercial operations began in early 2018 a few months later. Unit 4 was completed in late September 2018, and it began commercial operations in late December 2018.
Unit 5 and 6
CNNC began construction of Unit 5 and Unit 6 on December 27, 2015 and September 7, 2016, and has its own 1000 MW ACPR-1000 reactor.
The fuel loading of Tianwan Unit 5 was completed on July 13, 2020, the critical point was reached on July 30, 2020, and the grid connection was established on August 8, 2020.
Units 7 and 8
China National Nuclear Corporation and ASE signed a detailed contract for the construction of two VVER-1200 (Tianwan 7 and 8) on March 7, 2019. The construction of Tianwan 7 will begin in May 2021, and the construction of Tianwan 8 will begin in March 2022. Commercial operations are expected in 2026 and 2027.
