distribution system is a single-point impedance grounded system, installation of a
static wire system with multiple grounding and surge arresters on all three
phases at prescribed intervals should be considered. Surge arresters should
also be installed on pad-mounted distribution transformers at their primary
When open wire lines supplying power to high-reliability loads are extended
outside process areas that require high reliability, installation of automatic
reclosers should be considered outside the high reliability areas and properly
coordinated to limit supply interruptions.
Emergency Preparedness Facilities . Reliability, flexibility for operations, and safety of
personnel should be considered in the design of electrical distribution systems for
emergency preparedness facilities. Standby power sources capable of supporting full
operation of emergency loads for a minimum of 24 hours or for a period specified by the
design authority should be included in the design basis. Special-purpose receptacles
used to power equipment should have permanent labels to mark voltage, amperage,
number of phases, power source, etc.
Telecommunication Facilities . Design of power distribution to essential equipment
should consider uninterruptible power sources or emergency backup power sources.
Design coordination with equipment system specialists and DOE security personnel is
essential to determine the load demand. A plug-in connection to a portable generator
should be considered.
Automated Data Processing (ADP) Centers . Guidelines on electrical power for ADP
installations are provided in Federal Information Processing Standards Publication, FIPS
Radio Control Centers . In determining power supply requirements, it is reasonable to
assume that all the transmitters are keyed simultaneously while associated receivers
and other equipment and building services are in operation.
