shielding during the fuel element and control rod-handling operations. The
segments are matched male and female sections, which are water cooled
and weigh 12 to 15 tons each. Cooling water lines for the top shielding
segments and for the vessel cover shielding are brought to flush-mounted
floor boxes, from which connections are made to the shield pieces by means
of armored hoses equipped with "quick disconnect" couplings.
The concept of shielding in the High Bay Area permits
limited access during operation to the floor area above the active equipment
pit. The area between the active equipment pitand the reactor operating floor
will be known as the primary system water service area. The reactor operating
floor at elevation 32 ft is 2 ft thick reinforced concrete designed for a loading
of 2000 lb per sq ft. The 5-ft diameter stepped plugs in this floor are in line
with the holes in the active equipment pit ceiling to facilitate removal of
equipment. The walls of the primary system water service area are of rein-
forced concrete thick enough to support the upper portion of the building or
to provide shielding as required. This area contains the following items:
a. Reactor Water Purification System
b. Deaeration System
c. Reactor Water Makeup Pump and Storage Tanks
d. Shield Cooling System
e. Miscellaneous Auxiliaries .
The active equipment pit is a shielded enclosure which
surrounds the reactor pit on three sides. It contains the following items:
a. Forced Circulation Pumps
b. Reactor Feed-Water Pumps
c. Sump Pumps .
The ceiling of the pit is ordinary concrete, 4 ft thick, to allow limited access
to the primary system water service area above. The outer walls of the pump
cell also form the building walls and extend up to the 56-ft level. The lower
floor of this pit is 22 ft 9 in. below grade. The ceiling of the cell forms the pri-
mary system water service area floor. Stepped plugs, 5 ft in diameter, in the
ceiling provide openings for access to pumps and other equipment. Means for
cooling the active equipment pit are provided in order to maintain reasonable
temperatures in the area during reactor operation. A sump and sump pumps
are provided in the pit to permit removal and proper disposal of any water
which may accumulate in the pit as a result of leaks or accidental discharges.
The fuel storage pit (Fig. 5) is a water-filled well located
in the High Bay Area adjacent to the Primary System Water Service Area. The
walls and floor of the pit are constructed of ordinary concrete, 4 ft thick, to
provide radiation shielding for any personnel adjacent to the pit. The pit is of
sufficient size (approximately 12 ft x 16 ft) to accommodate two or more ir-
radiated cores simultaneously and still provide a reasonable amount of work
area. The pit is deep enough (approximately 23 ft) to permit a depth of water
over the fuel materials sufficient to maintain tolerable radiation levels at the
Here’s what’s next.
