Bechtel said the first of 1,485 major unit modules arrived on the Vogtle site in 2011, while the last reached the project in 2019. All modules were manufactured offsite and arrived at the project ready to be assembled into larger modules that make up each of the two units. The modules included plant components like floor and wall sections, as well as the supporting structures that surround the containment buildings and reactor vessels.
The Westinghouse AP1000 units the company is using are the first to be built in the U.S.
