Plant Vogtle Units 3 & 4:
DSI supplies DYWIDAG Form Ties for new Reactors
In February 2012, Plant Vogtle in Waynesboro, Georgia, USA, 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. Units 3 and 4 are set to be operational in 2019 and 2020 respectively. Once completed, Plant
Vogtle will supply approximately 1 million households and companies with energy and create 800 new jobs.
The two new reactors will have an output
of approximately 1,117MW each.
The construction of the two units includes
the cooling towers, nuclear islands, turbine
islands, and other concrete framed buildings.
For the construction of the reinforced concrete
structures, DSI Construction USA supplied
DYWIDAG Form Ties and other Concrete
Accessories. This included anchor bars
consisting of 15, 20 and 26mm Ø DYWIDAG
THREADBAR ® , shebolts, steel setting cones,
couplers, hex nuts, wobble anchors, welded
angle brackets and many other Concrete
Accessories.

A concrete volume of approximately
382,277m³ (500,000yd³) is needed for the
two new reactors. The 15 and 20mm Ø
DYWIDAG THREADBAR ® supplied by DSI
alone had a total length of over 3,000m
(9,842.5ft), and construction is still underway.
