Initial Construction Activities
• Clearing, grubbing, excavation, backfill, grading, and
dewatering
• Install temporary and permanent access roads and
drainage features
• Install temporary facilities – office trailers, change shacks,
underground electrical, water, fiber, laydown areas, and
concrete batch plant
• Set up site security – guard houses, fences, access gates,
badging facilities, etc.
• Build warehouses, offices, and Training/Simulator Building
• Relocate 500 kv transmission line interferences

1ST
Nuclear Concrete
• Nuclear Island Basemat is the foundation for the Reactor
Containment Building and the Reactor Auxiliary Building
and is the first safety related concrete placement
• Nuclear Island Basemat is six (6) foot thick and contains
over 6800 cubic yards of concrete
• This placement of concrete was rehearsed during a 1/6
size “mock-up” in September 2012 to ensure a successful
continuous pour
• The actual placement was delayed several months due to
rebar discrepancies in the design and final resolution
with the NRC
• In March 2013 the full size Nuclear Island Basemat was
placed successfully in approximately 51 hours

Some of the Facts
• Over 22 million cubic yards of earth were moved during
excavation and backfill while preparing the site for
construction
• The Nuclear Island area was excavated to a depth of
approximately 80 ft to remove unsuitable marl material and
replaced with Class I backfill
• The 70,000 square foot Simulator/Training Center took 1
year to complete and currently houses all operator training
activities
• The 13 story Modular Assembly Building is over 300 ft long
and is where structural modules are assembled and loaded
on heavy haul transporters for moving to the appropriate
plant location
• There are 23,000 tons of steel, 16M feet of cable, and 546,00
ft of piping associated with the two units
• There are currently over 2200 workers on site and the peak
workforce will be around 5000
