Information Notice No. 87-58: CONTINUOUS COMMUNICATIONS FOLLOWING
EMERGENCY NOTIFICATIONS
Addressees:
All nuclear power reactor facilities holding an operating license and the
following fuel facilities that have Emergency Notification Systems (ENS):
Nuclear Fuel Services, Erwin, Tennessee; General Atomics, San Diego, Califor-
nia; UNC, Montville, Connecticut; and B & W LRC and B & W Navy, Lynchburg,
Virginia.
Purpose:
This information notice is provided to clarify NRC's role in emergency
response and initial event analysis and to reiterate the responsibility of
licensees to maintain adequate personnel on shift to permit continuous
communications with the NRC in an emergency without diminishing the ability to
expeditiously place the plant in a safe condition. Recipients are expected to
review this information notice for applicability and consider action, as
appropriate, to preclude occurrence of similar problems at their facilities.
However, no specific action or written response is required.
Description of Circumstances:
On July 15, 1987 at 6:25 a.m., North Anna Unit 1 experienced a steam generator
tube rupture while operating at 100% power. The unit was manually tripped by
the operators, and an automatic safety injection actuation occurred on low
pressurizer pressure at 6:36 a.m. Safety injection was terminated by the
operators at 7:05 a.m. A small radioactive release to the environment oc-
curred via the main condenser air ejector exhaust and the auxiliary feedwater
pump turbine exhaust.
An Unusual Event was declared at 6:39 a.m., and the emergency classification
was upgraded to an Alert at 6:54 a.m. The licensee notified the NRC Headquar-
ters Operations Center of the event via the Emergency Notification System
(ENS) at 7:04 a.m. The Operations Center requested that the licensee maintain
continuous communications with the NRC via the ENS and provide updates of the
event status as additional information became available.
The NRC Region II Incident Response Center and the Headquarters Operations
Center were activated in the Standby mode. ENS communications were maintained
until the NRC Centers were returned to Normal mode at 12:41 p.m. The licensee
downgraded the emergency classification from Alert to Recovery when the unit
reached a cold shutdown condition at 1:31 p.m.

Discussion:
In a meeting with industry representatives after the event, licensee
management indicated a concern regarding the burden placed on the plant staff
by NRC requests for information during the event. In later discussions with
the licensee, the licensee stated that the intent during that meeting was to
inform other industry representatives of the importance of planning to provide
for communications with the NRC during an emergency.
10 CFR 50.72(c)(3) requires reactor licensees to maintain continuous communi-
cations with the NRC when they are requested to do so. This requirement was
reemphasized in Information Notice No. 86-97, "Emergency Communications
System." Information Notice No. 85-80, "Timely Declaration of an Emergency
Class, Implementation of an Emergency Plan, and Emergency Notifications,"
reiterated licensees' event notification responsibilities. Licensees have a
responsibility to provide enough on-shift personnel knowledgeable about plant
operations and emergency plan implementation to enable timely, accurate, and
reliable reporting of operating events without interfering with plant
operation.
The effectiveness of the NRC during an event depends in large measure on
complete and accurate reports from licensees. During an emergency, the Region
Incident Response Center and the Headquarters Operations Center become focal
points for action by the NRC. Licensee actions during an emergency are
monitored by the NRC to ensure that appropriate action is being taken to
protect the health and safety of the public. When requested, the NRC supports
licensees with technical analysis and coordinates logistics support. The NRC
keeps other Federal agencies informed of the status of an incident and
provides information to the media. In addition, the NRC assesses and confirms
the appropriateness of protective actions recommended by the licensee to local
and state authorities.
No specific action or written response is required by this information notice.
If you have any questions about this matter, please contact the technical
contact listed below or the Regional Administrator of the appropriate regional
office.
