The components - each measuring 24 metres long, 5.5 metres in diameter and weighing 640 tonnes - were delivered by Shanghai Nuclear Electric Power Company, State Nuclear Power Technology Corporation (SNPTC) announced.

In addition to the two Westinghouse AP1000 units being built at Haiyang, two more are under construction at the Sanmen site in Zhejiang province. Sanmen unit 1 is expected to be the first AP1000 to begin operating. All four Chinese AP1000s are scheduled to be in operation by 2016.

In April 2007, Westinghouse signed a $350 million contract with South Korea's Doosan Heavy Industries for two pressure vessels and four steam generators for Sanmen 1 and Haiyang 1. The pressure vessels for the other two units were made by Chinese manufacturers: China First Heavy Industries for Sanmen 2 and Shanghai Electric for Haiyang 2. Steam generators for Sanmen 2 and Haiyang 2 were manufactured by Harbin Power Equipment Company and Shanghai Electric, respectively, though a contract for Sanmen 2 steam generators was let to Spain's ENSA in 2011.

Four AP1000 reactors are currently being built in the USA - two each at Vogtle and Summer - while three AP1000s are also proposed for the Moorside site in the UK.
