1. Main Building
a. High Bay Area
This section of the building is to be 40 ft wide by ap-
proximately 85 ft long. It will extend from 22 ft 9 in. below grade to 72 ft
above grade (see Fig. 6).
(1) Free-Floor Loadings -
The reactor operating floor, Primary System
Water Service Area floor, and basement floor are to have a permissible
uniform loading of 2000 lb/sq ft. The upper floors will have stepped
access openings with concrete plugs to provide crane access to the forced-
(2) Walls and Foundations
The reactor and shield will weigh approximately
1500 tons and occupy a space approximately 28 ft in diameter and 34 ft high.
This structure will be attached to the building wall and supported on con- .
crete columns, and will extend from grade to 32 ft above grade level as
shown in Fig. 5. This shield must be constructed in two stages to facilitate
plant construction in advance of delivery of the pressure vessel. A con- ~
crete cylinder, 26 ft ID by 28 ft OD, extending upward from the Primary
Water Service Area floor to the reactor operating floor will permit con-
struction and erection of the remaining portions of the building, equipment,
and piping, independent of vessel delivery date. The cylinder forms will
be fabricated from carbon steel plate with sleeves and inserts for pene-
tration of the pipes, etc., required for attachment to the pressure vessel,
and will remain permanently in place.
After the pressure vessel, piping, insulation, etc.,
are placed, the remainder of the shield interior will be installed. Beginning
with the 1/2-in. thick by 11-ft ID carbon steel plate inner form, the neces-
sary pipe sleeves will be placed over the pipes, with water jackets for cool-
ing the concrete. The sleeves will be large enough to clear pipe insulation
and permit expansion during operation. Bellows will connect the pipes to
the sleeves at the outer face to seal off the reactor pit area.
Cooling coils as described in the auxiliary systems -
section (III-D-4, Item 19) will be attached to the outer periphery of the 11-ft
diameter inner form. A 3-in. thick lead annulus will be built up opposite the
straight portion of the reactor vessel around the cooling coils. This portion
will be fabricated by pouring lead in successive layers within steel bands
about 12 in. high by 1/4 in. thick.
