The construction of units 1 and 2 of the Xudabao (also known as Xudapu) plant was approved by China's State Council on 31 July last year.
On 6 November, the Ministry of Ecology and Environment announced that the National Nuclear Safety Administration had decided to issue a construction licence for Xudabao units 1 and 2, which will both feature 1250 MWe CAP1000 reactors - the Chinese version of the Westinghouse AP1000.
A ceremony was held on 15 November at the Xudabao site near Xingcheng City, Huludao, to mark the start of construction of unit 1.
The Xudabao project was originally expected to comprise six CAP1000 reactors, with units 1 and 2 in the first phase. Site preparation began in November 2010. The National Development and Reform Commission gave its approval for the project in January 2011. China National Nuclear Corporation (CNNC) noted that the total investment in units 1 and 2 exceeds CNY48 billion (USD6.6 billion).
However, with a change in plans, construction of two Russian-supplied VVER-1200 reactors as Xudabao units 3 and 4 began in July 2021 and May 2022, respectively.
"The Xudabao nuclear power plant has officially entered a new stage of comprehensive construction of two models and four units," CNNC said. "At present, the construction of the four units of the Xudabao nuclear power project is progressing in an orderly manner. Units 1 and 2 are scheduled to be put into operation and generate electricity in 2028 and 2029, respectively; units 3 and 4 have all entered the equipment installation stage, and all important milestone nodes have been achieved on schedule with high quality. They are scheduled to be put into operation and generate electricity in 2027 and 2028, respectively."

The Xudabao plant is owned by Liaoning Nuclear Power Company Ltd, in which CNNC holds a 70% stake with Datang International Power Generation Co holding 20% and State Development and Investment Corporation owning 10%. The general contractor is China Nuclear Power Engineering Company Ltd, a subsidiary of CNNC.
Two further CAP1000 reactors are proposed for units 5 and 6 at the Xudabao plant.
After all the six units of the plant are put into operation, they will provide more than 54 TWh of clean electricity every year, saving about 19.2 million tonnes of coal annually, and reducing carbon dioxide emissions by about 56.7 million tonnes annually, CNNC said.
With construction of Xudabao 2 under way, CNNC now has 12 reactors being built in China, with a combined generating capacity of 13.9 GWe.
