Workers at the Plant Vogtle nuclear expansion project on Nov. 21 completed placement of basemat structural concrete for the nuclear island at Unit 4, according to plant owner/operator Georgia Power. The utility called the placement "a significant accomplishment in the construction of the project."
Georgia Power, which owns 45.7% of the two planned 1,117-MW units, said the placement of about 7,000 cubic yards of concrete was finished in only 41 hours, which it said "matches the best time achieved worldwide" for similar work on other Westinghouse AP1000 units. Workers placed the basemat concrete for Unit 3 in March.
