7-3.3.3.1 Power Requirements for Fixed/Portable Inspection Equipment
The power requirements of fixed/portable systems vary widely depending on the system
type. Gamma-ray systems use a radioactive source to generate the transmission rays.
This requires less power compared to an X-ray system, which generates the x-ray
transmission using electro-mechanical means. Table 7-1 illustrates the potential power
requirements.

Inspection System
Power Requirements
Notes
100 kVA site power
Includes power to
AS&E Shaped Energy
inspection equipment and
ISOSearch X-ray
power for gantry transport
Inspection System
SAIC Portal VACIS
3 kVA per lane 120/240
VAC
30A , 220-240 VAC
Documentation indicates
SAIC VACIS II (track
5kW of backup power is
system)
sufficient for the VACIS II
system components,
additional power required
for operating booth,
HVAC, etc.
If an inspection system is specified, consult with the manufacturer concerning the latest
requirements for power. If no inspection system is specified, however, the future
inclusion of a system is likely, the design of the electrical power system should consider
an allowance to provide sufficient site power to support this future requirement.
