NRC REGULATORY ISSUE SUMMARY 2000-11
NRC EMERGENCY TELECOMMUNICATIONS SYSTEM
Addressees
All holders of operating licenses for nuclear power reactors.
Intent
The U.S. Nuclear Regulatory Commission (NRC) is issuing this regulatory issue summary (RIS)
to inform addressees about impending changes to the currently installed NRC Emergency
Telecommunications System (ETS). This RIS provides information on the process that will be
followed to modify the ETS at power reactor sites. This RIS also notifies addressees about a
voluntary, optional approach that would utilize corporate emergency telecommunications
systems in lieu of the NRCs dedicated circuits for providing ETS service.
Background Information
The ETS provides seven communication functions to nuclear power reactor emergency
response facilities. These communication functions are considered essential to the NRC
response to an event at a nuclear power plant. The ETS service is currently provided using
direct access lines (DALs) to the Federal Governments long distance network, FTS 2000.
These dedicated lines provide a direct connection to FTS 2000 and are not switched at the local
central office. This design feature is important because of possible call volume saturation at the
local telephone office during an emergency. The FTS 2000 contract will expire in December
2000. The General Services Administration has entered into follow-on contracts with MCI
WorldCom and Sprint for long distance service. The new service is called FTS 2001, and NRC
has selected MCI WorldCom as its FTS 2001 provider. All current ETS service is included in
the NRC plans for conversion to FTS 2001, and the transition will occur between August and
October of 2000.
In reviewing the options for a post-FTS 2000 ETS in SECY-98-194, (Accession No.
9812110073) the NRC identified a potential efficiency enhancement. The primary purpose of
the DALs is to provide access to long distance networks independent of the local telephone
switch. A consultant study and a survey of a representative cross section of licensee sites
indicate that most utilities have established corporate telecommunications capabilities that
already provide access to long distance networks without having to go through a local
telephone company switch. Therefore, ETS functionality could be provided over corporate
networks at minimal cost to licensees; this measure would eliminate the large recurring costs
associated with the NRCs dedicated circuits.
Page 2 of 3
Licensee costs would be restricted to costs associated with rerouting the ETS circuits to the
licensees network. All long distance charges would continue to be paid for by the Government.
Summary of Issue
The NRC requires reliable emergency telecommunications capability at nuclear power plants in
10 CFR 50.47(b)(6) and 10 CFR Part 50, Appendix E. The telecommunications functions
related to communication between the NRC and nuclear power plant control rooms and
emergency response facilities are currently provided by the NRC utilizing dedicated circuits to
the FTS 2000 network. Because of the expiration of the FTS 2000 contract, the ETS circuits
will be transferred to the follow-on FTS 2001 system using MCI WorldCom as the service
provider. The methodology for the service transition is discussed in Attachment 1.
In SECY-98-194, the NRC staff identified options for more efficiently providing ETS services for
nuclear power plants. The option supported by the staff and approved by the Commission
would involve the use of preexisting licensee communications networks to provide access to
long distance service in a manner that would be independent of the local telephone switch. In
the original formulation of this plan, rulemaking was the anticipated vehicle for accomplishing
this goal. Consistent with the Commissions decision on using industry initiatives in the
regulatory process, the staff has pursued the concept of a voluntary industry initiative to provide
ETS functionality using corporate communications networks through the Nuclear Energy
Institute (NEI). A number of utilities have already expressed interest in the initiative.
The NRC staff will continue to support the optional use of licensee communications networks to
provide long distance access to ETS circuits in those cases in which the licensees network can
route ETS calls to long distance service independent of the local telephone switch. Details of
this alternative approach are provided in Attachment 2. Licensees that desire to implement this
option in lieu of the planned cutover to FTS 2001 should notify the NRC ETS Project Officer,
John Jolicoeur, through their NRR Project Manager as soon as possible (preferably before
July 30, 2000). Requests received after July 30 will be accepted, but it may be too late to
preempt the installation of FTS 2001 service.
Please note that NRC staff will host a one-day workshop for those licensees who are planning
to implement the voluntary alternative described in Attachment 2 or are interested in obtaining
additional information about this option to make an informed decision. The workshop is
tentatively scheduled to be held on July 21, 2000, at the NRC Region III offices in Lisle, Illinois.
More detailed information concerning the workshop agenda and confirmation of the date on
which the workshop will be held is provided on the NRC Home Page which can be accessed
using the following URL: <http://www.nrc.gov/NRC/PUBLIC/meet.html#RIII>. The NRC point of
contact for prospective workshop attendees is John Jolicoeur, who can be reached at
301-415-6383.
Emergency Plan Revisions
Emergency Plan revisions to reflect the changes made to licensees emergency
telecommunications systems as a result of this RIS may be made in accordance with 10 CFR 50.54(q) and need not be submitted to the NRC for prior approval. Nevertheless, licensees are
required under 10 CFR 50.54(q) to conduct an analysis to determine that there has been no
decrease in the effectiveness of the plan as a result of these changes.
Licensees should use
this RIS as a part of its basis for that determination.

Backfit Discussion
This RIS requires no action or written response. Any action on the part of addressees to utilize
corporate communications systems to provide ETS circuits is strictly voluntary. Any
modifications made in the transition to FTS 2001 will be modifications to the NRC system.
Since neither of these items constitutes a backfit under 10 CFR 50.109, the staff did not
perform a backfit analysis.
Federal Register Notification
A notice of opportunity for public comment on this RIS was not published in the Federal
Register because the NRC has worked closely with NEI, industry representatives, and other
stakeholders in an open public forum since late 1998 on the need to upgrade the NRC ETS
service. Furthermore, the optional use of licensee communications networks to provide long
distance access to NRC ETS circuits, although a more efficient application of existing
communications capabilities, is strictly voluntary.
Paperwork Reduction Act Statement
This RIS contains a voluntary information collection that is subject to the Paperwork Reduction
Act of 1995 (22 U.S.C. 3501 et seq.). The NRC may not conduct or sponsor, and a person is
not required to respond to, a collection of information unless it displays a currently valid Office
of Management and Budget (OMB) control number. The collection of this information is
covered by OMB clearance number 3150-0011, which expires on September 30, 2000.

METHODOLOGY FOR NRC EMERGENCY TELECOMMUNICATIONS SYSTEM (ETS)
TRANSITION FROM FTS 2000 TO FTS 2001
At those locations in which the use of licensee communications networks is not an option or in
which the licensee chooses not to implement the option, the transition from the FTS 2000
(AT&T) network to the FTS 2001 (MCI) network will take place.
The three types of transition cutovers are as follows:
1.
Parallel - All new facilities are utilized, including the customer-provided equipment
(CPE). There are no contingency options needed for this type of cutover as all functions
are run in parallel before cutover.
2.
Managed - The new facilities can only be installed to a point within the users building
and not to the final termination point or the CPE. The gaining vendor (MCI) is
responsible for managing all facets of the transition process. Contingency options that
allow the NRC to fall back on AT&T-provided facilities are necessary if operational
requirements are not met under the new service.
3.
Coordinated - This type of cutover should only be used when all other options have
been exhausted. This option does not allow for any contingency plans and is, therefore,
the option with the highest risk. The NRC ETS services will, for the most part, utilize the
managed cutover option. The use of a coordinated cutover will only be implemented
when the local exchange company (LEC) access is unable to accommodate the
installation of new services to the licensees main distribution frame (MDF). Timelines for
the three types of cutovers are listed at the end of this methodology.
The following methodology will be used to perform the ETS transition in order to minimize the
overall risk to the ETS transition:
Pre-Transition Testing: Before the local exchange companys firm order confirmation (FOC)
date for the delivery of the new service, each of the NRC ETS functions should be tested by the
licensee to achieve the following:
1.
Ensure the continuity of the licensee-provided inside wiring.
2.
Minimize the impact of problem resolution during the transition process.
Transition Rotation: If there are limitations to the availability of inside wiring with respect to the
Control Room from the MDF, each of the ETS functions will be rotated in the manner described
below using existing wiring, where possible. [Note: (1) Each step of the transition will be tested
as described under Testing Methodology to ensure full duplex call completion and connectivity;
(2) At those locations in which the Emergency Offsite Facility (EOF) is fed by different LEC
facilities than the main plant, the Management Counterpart Link (MCL) and the Operations
Center Information Management System Local Area Network (LAN) functions have been
Attachment 1
Page 2 of 5
removed from the plant Technical Support Center (TSC); (3) The Emergency Response Data
System (ERDS) does not exist at the EOF.]
1.
When possible, a spare cable pair into the Control Room or the Emergency Notification
System (ENS) connection in the TSC shall be used to test the MCI-provided ENS
function. If a spare cable pair does not exist or the TSC ENS use interferes with the
operating ENS connection, one of the counterpart links in the TSC shall be used to test
the new MCI ENS as described under Testing Methodology. Once the new MCI ENS
has been functionally tested and accepted, a managed transition of the Control Room
and TSC locations will be performed, followed by another test and acceptance period.
2.
The next function to be transitioned will be the Management Counterpart Link (MCL)
where applicable. The inside wiring from the MDF to the TSC will be used to support
the new MCL function. This practice will leave the FTS 2000 MCL terminated at the
MDF of the site.
3.
The next function to be transitioned will be the Protective Measures Counterpart Link
(PMCL), which will be treated in the same manner as the MCL function.
4.
The Reactor Safety Counterpart Link (RSCL) will be similarly transitioned next.
5.
The Health Physics Network (HPN) function will be the next function to be transitioned
and tested.
6.
The ERDS located in the licensees computer room will then be transitioned.
7.
The final ETS function to be transitioned is the Operations Center Information
Management System (LAN) function where applicable. If required, the LAN will be
transitioned the same as in step 2 above.
Testing Methodology: Testing as part of this transition program is performed in two parts:
1.
Pre-Transition Testing:
a.
The licensee shall assist in the functional testing of each of the ETS functions
before transition to ensure the existing cable path and the NRC CPE are
functionally compliant with the service requirements.
b.
Functional testing is defined as the ability of the ETS function to pass two-way
call testing with the NRC Operations Center or other designated test point.
c.
For those functions that do not pass the functional testing, isolation of the
problem shall be conducted to ensure the continuity of the licensees cable path,
terminations, and the NRC CPE.
Attachment 1
Page 3 of 5
d.
If the licensees cable path and the NRCs CPE are not at fault, the NRC ETS
Technical Contact or designee shall be notified. The NRC shall open a trouble
ticket with the FTS 2000 vendor for resolution. The NRC will be responsible for
tracking the problem to resolution, and the licensee will provide assistance as
necessary to resolve issues with the licensees cable plant.
e.
Once determined to be functional, the service will be declared ready for
transition.
2.
New Service Acceptance Testing
a.
The licensee shall assist the NRC in the functional testing of each of the new
ETS functions as they are declared ready for customer acceptance testing by
MCI.
b.
The testing shall mirror the pre-transition testing, with non-functional services
being referred immediately to MCI for resolution.
c.
The NRC will be responsible for tracking the problem to resolution, and the
licensee will provide assistance as necessary to resolve issues with the
licensees cable plant.
d.
Once performed, the acceptance testing will recommence for verification and
acceptance of the new service.
Information Dissemination: MCI will be responsible for providing the NRC and the licensee with
circuit information and other pertinent information related to each of the functions.
Licensee Responsibilities: The licensee will be responsible for the following actions in support
of this effort. It is estimated that a half-day will be required per site to perform the transition. A
site is defined as a location at which all ETS functions are fed from the same MDF. When the
EOF is fed by different LEC facilities than the main plant, the EOF is considered a separate site
and an additional half-day is required. These additional sites will be treated as a new location
for the purposes of the transition.
1.
Making the cross-connect changes to accomplish the seven steps previously mentioned
during the transition process.
2.
Assisting the NRC in making continuity and/or functionality testing both before the
installation as described in the pre-transition testing phase and as part of the service
acceptance testing after transition.
3.
Making available, when feasible, one preexisting cable pair from the MDF to the Control
Room to support the new MCI ENS function as identified in step 1 of the above-
mentioned transition rotation description.
4.
Providing the necessary resources to accomplish these three functions.

VOLUNTARY ALTERNATIVE EMERGENCY TELECOMMUNICATIONS SYSTEM
(ETS) IMPLEMENTATION
The NRC currently provides reliable long distance telephone service to nuclear power plant
sites and remote Emergency Operations Facilities (EOFs) for the following seven essential
telecommunications functions:
1.
Emergency Notification System (ENS) - The ENS is used for communication between
the NRC and the licensee. It is the normal circuit for event reporting. It is also used to
communicate reactor safety-related information between the licensee and NRC during
event response.
2.
Health Physics Network (HPN) - The HPN is used for communication of radiological and
meteorological information between the licensee and NRC during event response.
3.
Reactor Safety Counterpart Link (RSCL) - The RSCL is used for communication
between NRC reactor safety team personnel at the site, regional office and
headquarters. The NRC Resident Inspector will normally communicate on this circuit.
4.
Protective Measures Counterpart Link (PMCL) - The PMCL is used for communication
between NRC protective measures team personnel at the site, regional office, and
headquarters.
5.
Management Counterpart Link (MCL) - The MCL is used for communication between
the Site Team Leader (Director of Site Operations), the Headquarters Executive Team,
and the regional Base Team Manager.
6.
Operations Center Local Area Network (LAN) line (OCL) - The OCL is an analog phone
line that is made available for accessing the NRC Operations Center LAN using laptop
computers with internal modems.
7.
Emergency Response Data System (ERDS) - One analog phone line per reactor unit is
used for establishing the links between the licensee computer systems and the NRC
ERDS.
This service is currently provided using direct access lines (DALs) to the Federal long distance
service (FTS 2000), which is currently provided by AT&T (as shown in Figure 1). During the
accident at Three Mile Island (TMI), telephone network congestion at the local telephone switch
serving the site prevented the establishment of communications between the NRC and the site
during the early phases of the accident. The current ETS design using DALs to bypass the
local telephone switch ensures that emergency calls can be made even if the local telephone
switch is congested as it was in the TMI accident. The NRC is aware that most nuclear power
plants have corporate communications systems that do not depend on the local telephone
switch. In those cases, it may be feasible for licensees to provide long distance access for all
ETS functions.
Figure 1: Existing NRC Telecommunications System
Attachment 2
Page 2 of 4
The staff would consider licensee telecommunications systems acceptable for the current ETS
if they, like the DALs, do not rely on the local telephone switch. This idea is illustrated
conceptually in Figure 2. The NRC believes that licensee telecommunications systems in many
cases may be just as reliable as the DALs, especially if they can reach the public switched
network (PSN) using independent means without going through the local telephone switch. The
importance of independence was illustrated by the experience at Davis-Besse on June 24,
1998, when a tornado destroyed all modes of telecommunications at the site except the
licensees corporate microwave system. The Control Room operators had one circuit available
on that network, which was used to communicate with the NRC, which subsequently notified the
State authorities of the conditions on site. Examples of acceptable paths for ETS access to
long distance networks include the following:
Land lines through an onsite private branch exchange (PBX) out to the utility network
A microwave link to the PSN (e.g., through a corporate office)
A corporate fiber network
A satellite system
Any other telecommunications system or network that can provide long distance access
independent of the local telephone switch.
Figure 2: Proposed NRC Emergency Telecommunications System
Attachment 2
Page 3 of 4
In order for licensees to provide ETS access, the current ETS telephones or modems (for
ERDS) would have to be re-routed to be carried on a corporate system as previously described.
This task could be accomplished by routing the circuits through the site PBX. This measure
would provide access to multiple paths for call routing. Otherwise, the circuits could be re-
routed at the main distribution frame to the system selected for ETS services. If directed
through a toll-free (800/888) exchange, the cost of long distance calls associated with ETS will
be paid by the Government. In addition, the NRC Operations Center accepts all calls (toll-free,
commercial, or collect) from any person reporting a nuclear emergency, regardless of whether
the ETS is involved.
For those plants with offsite EOFs, the possibility exists that adequate communications facilities
to implement this plan might only exist at one of the two locations (i.e., either the plant or the
EOF). In this case, the methodology discussed above could be used at one of the two locations
and FTS 2001 DALs would be provided at the other.
Attachment 2
Page 4 of 4
The portable satellite telephones provided to each NRC Resident Inspector will remain on site
and will be made available for emergency reporting in cases of total loss of telecommunications
to the site.
Implementation of this voluntary initiative would entail the following:
1.
Reviewing site telecommunications capabilities to verify that ETS circuits can be
provided access to long distance service by way of existing site systems that are
independent of the local telephone switch that serves the site.
2.
Notifying the NRC, in writing, of your intent to provide ETS services utilizing corporate
communications systems. Your notification should describe the system proposed for
providing ETS service and should give a point of contact.
3.
Rerouting of all current ETS service through the onsite telephone system. Provide a list
of the telephone numbers for the ETS circuits that have been placed on corporate
communication systems to the NRC ETS Project Officer (John Jolicoeur, IRO).
4.
Ensuring the ERDS and Operations Center LAN circuits are analog circuits.
5.
Conducting tests of the newly installed circuits with the NRC Operations Center.
6.
Revising procedures, as appropriate, for operation with the newly installed ETS service.
7.
Providing dialing instructions at all ETS locations for each call routing option available.
8.
Making arrangements with the NRC Senior Resident Inspector to the NRCs portable
satellite telephones.
