The full-power demonstration test run of Haiyang Unit1 was completed at 22:12 on 22nd, October, 2018. The reactor has now been "put into commercial operation conditions". 

In September 2007, the construction of four AP1000 units in China was permitted by the authorisation: two at Sanmen in Zhejiang province and two more at Haiyang in Shandong province. Construction of Haiyang 1 and 2 began in September 2009 and June 2010, respectively.

The loading of fuel assemblies into its core began on 21 June. The unit achieved first criticality - a sustained chain reaction - on 8 August. Haiyang 1 was connected to the grid on 17 August, and reached 100% power for the first time on 25 September.

The successful construction of the Haiyang nuclear power project is an important achievement in the development of China's third-generation of nuclear power plants, and will vigorously promote the industrialisation of China's independent passive nuclear power technology.
