3. Power and Lighting
Power for the ARBOR Facility shall be obtained from the
main 13,800-v bus at the main Site 16 substation location, about 1/2 mile
away. The total demand load for the facility is estimated to be 9000 kw.
The Architect-Engineer shall include in his design the necessary 13,800-v
power transmission line for two feeders, and shall design the local sub-
station needed to transform and distribute this power at the ARBOR site.
An emergency power system shall be provided to supply
sufficient power to critical components to permit orderly shut-down of the
plant. This system shall consist of a diesel generator set equipped for
automatic start-up in the event of simultaneous failure of both power
feeders. The generator shall supply 440-v, 3-phase, 60-cycle AC to an
emergency power circuit which is normally fed from the regular 440-v
bus, and to which are connected the items listed below. The diesel gener-
ator shall be capable of carrying this load for a minimum of eight hours
1. Selected lights throughout the plant areas, sufficient
to insure personnel safety.
2. All lighting in the Control Room
3. All instrumentation and motorized valves.
4. Instrument air compressor
5. Forced-circulation pump No. 1 (440-v emergency
6. Cooling water circulating pump.
7. Shield cooling circulating pump.
8. Control room air conditioners
9. Food freezer, refrigerator, and cooking stove
10. Public address system.
11. Sump pumps.
Consideration must be given to the need for applying the
emergency loads to the diesel generator in time-delayed steps rather than
all at once, in order to prevent overload of the generator and/or the diesel
engine starting motor.
A line diagram showing a suggested electrical distribution
system for the ARBOR Facility is given in Fig. 13.
Lighting in the high bay and auxiliary equipment areas of
the main building shall be provided by incandescent fixtures capable of
producing a minimum of 30 ft-candles of illumination at all work surfaces.
Duplex convenience outlets of the combination two- and three-pole type for
110-v service shall be spaced at about 10-ft centers around all work areas.
Outlets providing 208-v and 440-v, 3-phase service shall be spaced to
service approximately 1000 sq ft of floor area each.
