Background
The Savannah River Site, a 310 square mile site, is located in the
south eastern coastal area of the United States in the state of
South Carolina. It is bordered to the west by the Savannah River
and Georgia, and is close to several major cities, including Augusta
and Savannah.(GA.), Columbia, Greenville, and Charleston (S.C.).
It is in an area residents refer to as the Central Savannah River
Area, or CSRA.

Site Facts
•
•
The site was built during the 1950s to refine nuclear materials for deployment in
nuclear weapons. It covers 310 square miles (800 km2) and employs more than
10,000 people.
It is owned by the U.S. Department of Energy (DOE). The management and
operating contract is held by Savannah River Nuclear Solutions LLC
(SRNS)(Savannah River Nuclear Solutions (SRNS), LLC - now a Fluor partnership
with Honeywell, and Huntington Ingalls Industries (formerly part of Northrop
Grumman)), and the Liquid Waste Operations contract is held by Savannah River
Remediation, which is a team of companies led by URS Corporation.

Home to the Savannah River National Laboratory.
Contains the nation's only operating radiochemical separations facility.
Tritium facilities are also the United States' only source of tritium, an essential component in
nuclear weapons.
The nation's only mixed oxide fuel (MOX) manufacturing plant is being constructed at SRS.
When operational, the MOX facility will convert legacy weapons-grade plutonium into fuel
suitable for commercial power reactors. On August 1, 2007, construction officially began on
the $4.86 billion MOX facility. The current deadline for the completion of construction is 2014.
Following startup testing, the facility would begin operations in 2016 with a disposition rate of
up to 3.5 tons of plutonium oxide each year. The mission is supposed to end in 2035, although
it could be extended to 2038.
Major focus is cleanup activities related to work done in the past for the nation's nuclear
buildup.
Currently none of the reactors on-site are operating, although two of the reactor buildings are
being used to consolidate and store nuclear materials.
Future plans for the site cover a wide range of options, including host to research reactors, a
reactor park for power generation, and other possible uses.

Accomplishments – RF Team
• Don Gregory - pioneered the development and implementation
of the RF Networking in Limited and Protected Areas at SRS
DOE facilities. (Started project in 2003)
• Pervis Rouse – Joined the team in 2005 to assist in further
development/implementation.
• Scott Rogers – Canberra has provided and continues to
provide primary technical support to the effort.
5
First Step: Determining the Requirements
 DOE: Limited and Protected area’s systems must be FIPS 1402 compliant.
•
•
DOE requires Radio Frequency (RF) transmitting equipment used in Limited Areas,
Protected Areas or Higher to be certified compliant with Federal Information
Processing Standards (FIPS) 140-1 or 140-2.
NIST FIPS 140-2 Validation Certificate 311 validates that the Cranite Wireless
(Wireless Wall) Access Controller is FIPS 140-2 compliant.
 SRS DOE: SSID must be non-descriptive and hidden.
 RF Network System can not be connected to the Site Network
System.
 Limited access and control of Facility specific encryption
credentials (Wireless Wall 4 specific security files).
 Controlled user name and password protection.
6
First Step: Determining the Requirements (cont.)
 RF transmissions less than 1 Watt (30dbi).
 All RF transmissions should be greater than 100ft from any
classified processor.
• Can be 50ft with increased restrictions and annual approval
 All IP addresses used should be from a specific block of
Fixed IP Addresses issued by Computer Security.
 SRS Radio Group has to approve the radio frequency and
channel for each application prior to testing and
installation 2.4GHz.
7
Second Step: Getting the RF Network System Approved
 A Test Plan out lining the proposed test of the RF Network
system was summited to DOE and Site Technical Security and
Computer Security for approval
 After DOE initial approval, summit test plan to Site
Contractor’s Technical Security and Computer Security, Cyber
Security, Management, and Radio Shop for approval.
 After approval the test was completed by setting up a test RF
Network system in an unrestricted area for testing, review and
evaluation by:
• DOE Technical and DOE Computer Security approval
• Site Technical and Computer Security approval
• Computer Cyber Security approval
• Radio Shop RF frequency approval
8
Facility Testing Approval
 A Test Plan is then developed and summited for each
proposed facility application detailing the information on the
proposed testing:
• Specific information on the RF equipment to be tested
(make, model, quantity, and technical specification)
• All test location including RF sensitive installed equipment
and distance from all classified processors in the facility.
• All equipment is removed from the facility at the end of
each day’s testing.
• Coordinate testing with facility operations and technical
security and security force.
9
Facility Testing Approval (Cont)
• Develop documentation for approval for Temporary
installation and testing of the RF Network:
• DOE Technical Security
• DOE Computer Security
• Site Technical Security
• Site Computer Cyber Security
• Facility Technical Security
• Facility Operation
• Security Force
• Radiological Control Operation
• Radio Shop
10
Post Testing
• Develop documentation for approval for installation of the RF
Network:
• DOE Technical Security
• DOE Computer Security
• Site Technical Security
• Site Computer Cyber Security
• Facility Technical Security
• Facility Operation
• Security Force
• Facility Radiological Control Operation
• Radio Shop
11
Final Step Testing
• Testing the RF communication with each component in the RF
Network system.
• Testing the alarm capability of each component both in the
field and at the Base Station.
• Testing the failure indication for each component both in the
field and at the Base Station.
• Verify each component transmits all required information.
• Verify Two way communication with Thermo Fisher RMS3C5
Area Radiation Monitor.
• Verify Spectrum on Canberra ALPHA CAM.
12
Cost Savings: Selling Points
 Initial cost avoidance of hard-wired networked system
installations.
• Much less expensive than the installation of hard-wired systems. This is
particularly true for older existing radiological facilities.
• For D&D (Decommissioning and Demolition) Facilities, Wireless Systems can be
removed before building demolition and be re-used.
 Reduced man-hours and materials associated with source
checks and alarm responses for ARMs and CAMs.
• Using the Eberline RMS3/DA1-6CC Area Radiation Monitor Source
Checks can be preformed remotely; Alarms can be acknowledged and
the status of the entire network checked remotely prior to leaving the
RCO office and/or Control Room. Can have multiple access points to
facilitate facility operational requirements.
13
ALARA: Selling Points
 Reduced worker radiation and contamination exposure.
• Following an alarm RCO can perform initial investigation
without entering an unknown radiation or airborne
contamination condition. Routine operational checks and
source checks on ARMs can be performed without entering
a radiation area. Routine operational checks and alpha
spectrum can be viewed on Alpha CAMs before entering
the contamination area.
14
Operational: Selling points
 Improved Facility operational control.
• For ARMs and CAMs the alarm and operational status of
the network can be checked at the operational center or
any access point. The Control Room and the RCO office
can get alarms and have full access to the information at
the same time and avoid notification errors.
 Improved alarm and operability communications.
• The status and operability of the monitoring equipment can
be checked real-time. Changes in radiological condition on
special jobs or operations can be monitored closely.
15
Operational Selling Points (Cont)
 Flexibility in the deployment of equipment.
• Relocation of portable and fixed monitoring equipment can
be completed quickly reducing exposure to radiation and
contamination.
 Operational data electronically archived and will enhance
reconstruction of events and job planning.
• Operational data is date/time stamped and electronically
saved daily. In the event of an incident the operational data
on all of the associated equipment can be reviewed.
Previous events/jobs can be critiqued to reduce exposure
and time in the area.

CRANITE - WIRELESS WALL
• Provides government certified security software for WLANs
• Wireless Wall carries a FIPS 140-2 rating. FIPS is short for
Federal Information Processing Standards; the 140
cryptographic standard was created by the National Institute
of Standards and Technology (NIST). The standard has four
levels of security - Level 1, Level 2, Level 3, and Level 4 -- that
increase in quality as they go up. FIPS 140-1, the first level,
only supports DES and 3DES encryption. The various levels
are suitable for a wide array of areas in which cryptographic
modules could be used.
• Wireless Wall generally comes with three pieces: the policy
server, an access controller for each subnet of the network,
and client software for each PC/Code Talker.

Proxim Orinoco AP-4000 Access Point - Repeater
In computer networking, a wireless access point (WAP) is a device that
allows wireless devices to connect to a wired network using Wi-Fi,
Bluetooth or related standards. The WAP usually connects to a router (via a
wired network), and can relay data between the wireless devices (such as
computers or printers) and wired devices on the network.
