Pressure vessel for AP1000 nuclear reactor in China put in place

The pressure vessel for the Westinghouse AP1000 nuclear reactor in China was put into place Sept. 22.

Construction of the Sanmen nuclear power plant in China has reached a milestone with the installation of the pressure vessel for the first reactor.

China's State Nuclear Power Technology Corp. (SNPTC) is building one of the world’s first AP1000 reactors at the Sanmen nuclear power plant. The component was made by Doosan Heavy Industries in South Korea using some forgings from China First Heavy Industries. It was shipped to Sanmen in July and lifted to a height of 54 metres (177 ft.) in order to enter the reactor building through its open roof and then lowered into place.

The vessel head and control rod drive mechanisms are to be shipped and installed separately.

Construction at Sanmen’s second reactor was fitted with the third ring of the containment vessel on Sept. 19. The same work was carried out at Unit 1 last September.
