CHAPTER II, SECTION 3
No serious difficulties were experienced
with this large Station. The tying of the closely
spaced reinforcing bars was time-consuming. An
airlift shuttle service was required between the
construction site and the camp on Fox to reduce time lost in travel.
A total of 822 cubic yards of concrete was
poured with an average 28-day strength of
4,200 psi.

The station was existing building, CASTLE
leads in 2-inch conduit.
Conduits from this
power panelcarried circuits into the station for
light and utility receptacles, thermostat and
humidistat, and instrument power. Conduits
were also led with wires from the timing cabinet to two explosion-proof links. A 16-circuit
submarine cable from Dog terminated in a cast
iron weatherproof junction box mounted outside of the station. From this box, 14-inch
conduit led to the terminal cabinet inside the
station and carried the circuits for User signals,
the door-closing signal
telephone.

The dehumidification equipment was lo-
cated on a concrete pad outside of the station.
A direct expansion-type coil, 2 square foot face
area, 65,000 btu/hr and using Freon 12, was
installed in the primary air system. An 822 cfm
fan located on the equipment slab supplied air
to the station through a 12-inch round steel
duct. A 20” x 16” x 2”air filter in an aluminum
housing was connected to the fan inlet. Exhaust
was through a 12-inch round steel pipe duct
with two 90-degree bends for radiation protection. The Freon 12 refrigerant system had a dx
coil and a 5.4-ton capacity air-cooled compressor. A refrigerant liquid receiver was installed
below the condenser. A 10 KW air duct heater
was used to reheat primary air.
Two 18”-square 2”-thick steel-plate slideing doors mounted in steel housings and held
in open position with %-inch wire rope connected to explosive blast links provided for
closing the air openings prior to the blast. A
fuel supply system for the generators consisted
of a 1,000-gallon steel tank, all welded, 6’-11”
diameter, 7’-6” long and with fuel lines to and
from the engines.
Station 1210 to which was added a concrete
wall at the front and roof for radiation shielding;
a reinforced concrete building at the rear; and
a sight tube structure in the forward area.
The shield wall extended up the forward
wall and over the roof for half the width of
the existing building and its entire length. This
new wall was doweled into the existing roof and

The reinforced concrete building began at
the rear wall of the existing structure and extended back 31’ to a 90-long retaining wall;
the building was 48 wide and the walls and
slabs were 3 feet thick. A large opening was
provided in the rear wall to permit installation
of equipment. This opening was provided with
a steel-framed blast panel 7’ x 8high which
would normally remain closed. Access to the
addition was provided by means of a steelframed blast door 4’ x8’ high with additional
access by means of a vestibule containing an
interior steel-framed blast door 2’-6square.
The tunnel of the existing building was
damaged during prior events and was removed.
The new tunnel was incorporated within the
addition. In order to allow the addition to
act as a unit with the existing building in resisting blast load, the roof, base slab, and ex-
terior side walls were doweled into the existing
structure. An exterior monorail hoist was installed over the rear blast door. Mounted on the
roof of the new addition, at the rear, was an
exhaust pipe housing of reinforced concrete, 9’
x 25’ long x 4’ high, with two steel hydraulically-operated blast-resistant vent doors.
In front of the existing station was a re-
inforced concrete baffle wall and retaining wall
