In February 2012, Plant Vogtle in Waynesboro, Georgia, was approved for the construction of two new nuclear reactor blocks: Units 3 and 4. This is the first time new reactors have been approved in the USA since 1978. Units 3 and 4 are an addition to the original Units 1 and 2 that were built in the 1980s. The new units are set to be operational in 2019 and 2020 respectively.
The two new reactors will have an output of approximately 1,117 MW each. Once completed, Plant Vogtle will supply approximately 1 million households and companies with energy and create 800 new jobs.
The construction of the two units includes the cooling towers, nuclear islands, turbine islands, and other concrete framed buildings.
Concrete volume of about 382,000 m³ needed
A concrete volume of approximately about 382,277 m³ (500,000 yd³) is needed for the two new reactors. The threaded rods supplied by DSI alone had a total length of over 3,000 m (9,842.5 ft).
For the construction of the reinforced concrete structures, DSI Construction USA supplied form ties and other Concrete Accessories. This included anchor bars, shebolts, steel setting cones, couplers, hex nuts, wobble anchors and welded angle brackets.
