Weighing nearly 1,000 tons and towering more than five stories tall, the module is the heaviest lift at the project so far this year. A 560-foot tall heavy lift derrick, one of the largest cranes in the world, lifted it into place. It houses various plant components, including the used fuel storage area.
The CA20 module was assembled from prefabricated wall and floor sections within the Modular Assembly Building at the Vogtle site, including submodules produced at the Lake Charles and Vigor facilities.
At Unit 3, 28 shield building panels are now in place, along with two additional roof truss modules completed for the Unit 3 turbine building, as well as significant concrete placement on the west side of the Unit 3 nuclear island.
Units 3 and 4 are 1,100-MW Westinghouse AP1000 reactors. They are set to be in service by 2019.
