Weighing 1,100 tons, the CA20 module was placed into the Vogtle Unit 3 nuclear island using a 560-foot heavy lift derrick, one of the world’s largest cranes, according to a Georgia Power news release.
The five-story tall module was assembled from prefabricated wall and floor sections and measures 67 feet long and 47 feet wide. It will house various smaller components, including the used fuel storage area.
Because of delays in shipping and assembling some submodules of the module from a Lake Charles, La., facility, contractor Chicago Bridge & Iron delivered remaining components to the Vogtle site for inspection and repair work, according to a report filed last month with the Georgia Public Service Commission.
Vogtle’s new Westinghouse AP1000 units are the first new nuclear reactors built in the U.S. in more than three decades. Units 3 and 4 are scheduled to come online in the fourth quarters of 2017 and 2018.
