' Emergency Classification and Notifications
'
n
?
The NRC' inspector's held discussions with key licensee reactor operations
staff and examined logs and records to determine whether the licensee's
emergency classification and subsequent notifications had been performed
iniaccordance with:the RERP.,-Sections 4.0 and 6.0, and RERP Implementing
,
Procedure RERP-CR, " Control Room Procedure."
'
y
,
,
The'NRC inspdctors' determined that the shift supervisor on duty when the
,
fire. occurred. classified the emergency and declared an Alert at 12:30 a.m.
- ('approximately 30' min'utes after the fire was detected) based on the nature-
of the fire and'the difficulty which had been experienced in establishing
stable core.cocling.
The shift supervisor stated that this classification
was made withost' entering _the procedures.
An assessment of the
.,
classification, subsequently conducted in the TSC at 1:55 a.m. , verified
,
that-this classification was appropriate and consistent with-the Alert
1
Emergency Action Level,(EAL) No. 10, " Serious fire which could lead to
substantial degradation of plant systems." The Alert classification was
,
terminated by the CED in the FCP at 8:17 a.m., based on a determination
L
!:,
,that the plant was in a safe and stable' condition, and the Recovery Phase
!
initiated in accordance with Section 9.0 of the RERP.
The inspectors
l
noted that the initial classification and subsequent declassification of
1
the emergency appeared to be consistent with the RERP.

'The N'RC inspectors determined that the control room attempted to activate-
-
_
.
_
the emergency pager system in Denver for notification of the emergency
l
L
- response organization personnel at the time of the Alert classification,
but were unable due to the loss'of offsite telephone lines, except for the
i
local lines to Greeley'and Longmont, as a result of fire damage to the
telephone cable in the. turbine building.
The shift supervisor first
i
attempted to contact the operations superintendent, but was unsuccessful.
He then was able to contact the assistant operations superintendent on a
' local .line at about 12:40 a.m.
The assistant operations superintendent
activated the pager sys+.em from his home at 12:43 a.m.
'The encoded pager
message for.all of the emergency response organization staff notified them-
of the Alert, the wind direction, the location of the PCC, and the
f
l
requirement to call back a verification that the message had been received
!
and notified.them to respond to the emergency response facilities in
accordance with the staffing plans.
It was later found that the callback
verification system did not work,' as it depended on an offsite telephone
,
link to a computer at the plant.
{
In regard to offsite agency notifications, the inspectors noted that the
i
Jcontrol room initial calls were made to the Colorado Department of Health
'
at M 2:48 a.m...the Weld County Emergency Communications Center at.
12:50 a.m., and the NRC Operations Center at 1:08 a.m.
The NRC inspectors
determined that these notifications webe timely in relationship to the
status of the emergency, but wereLapproximately 3 and 5 minutes,
respectively, in excess of the 15 minutes specified in the RERP and
!
procedures for notifying the state and local agencies. The' primary factor
in the delay of these notifications apparently was the unexpected delay
1
incurred in activating the emergency response pager system.
!
During interviews with the licensee's staff, the NRC inspectors found that
l
^
there had'been a lapse in the offsite notification network, in that the
,
Weld County Emergency Communications Center had not notified the Colorado
,
Department of Disaster and Emergency Services of the Alert classification
l
as required in the offsite plans.
Apparently the Weld County communicator
recognized that no additional Weld' County. support was necessary to respond
i
to the fire, but did not recognize that additional notification was
required.
The Federal Emergency Management Agency (FEMA) will follow up
on this observation during a remedial alert and notification drill to be
conducted in the near future.
No violations or deviathns were identified.

Emergency Response Facilities Staffing and Activation

recor K and held discussions'with key emergency response organization
personnel to determine;whether the staffing and activation of the
licensee's emergency response facilities had been in accordance with the
RERP, Section 6.0, and RERP Implementing Procedures RERP-TSC, " Technical
%
Support Center Procedure;" RERP-PCC, " Personnel Control Center Procedure;"
and RERP-FCP, " Forward Command Post Procedure."

Section 6.0 of the RERP states that all onsite and offsite energency
response facilities will be staffed for emergency classifications of Alert
and above.
The inspectors noted that the first responders to the
I;
. emergency pager notification arrived onsite at about 1:15 a.m. and at the
FCP approximately 1:40 a.m. . Staff augmentation continued until all of the
emergency response facilities were fully staffed and declared activated as
follows:
Emergency Response Facility
Time Staffed and Activated
1:58 a.m. (*88 minutes)

Personnel Control Center
2:59 a.m. (149 minutes)
l
Forward Command Post
3:45 a.m. (195 minutes)
__________________________

i
L
The inspectors noted that the times to achieve minimum staffing and
activation of the FCP and PCC were significantly in excess of 90 minutes,
the staffing time commitment made to the NRC in letters dated August 28,
1980, and December 7, 1981.
The failure to meet this staffing time frame
represents a deviation from a commitment to the NRC (267/8728-01).
The inspectors discussed the delays in achieving the st'affing commitments
with the facility emergency directors and reviewed the staffing checklist
records.
For the PCC, it was determined that the minimum staff
discrepancies of three health physicist staff and the maintenance
supervisor prevented activation within the required time.
In the FCP, it
was noted that five of the minimum staff, including the CED, had arrived
by 1:55 a.m.
The remaining positions af Dose Assessment and Technical
Liaison and were not filled until 3:05 a.m. and 3:32 a.m. , respectively.
The common factors in the staffing delays appeared to be:
(1) the failure
of personnel to maintain the pagers in a mode to alert them at all times
and (2) a limited number of alternates for each emergency response
organization position.
The failure of the call-back system also revealed
that there was no alternate, notification verification procedure to
implement if the system went down.
Ne violations were identified.

Exit Interview
The NRC inspectors met with the NRC senior resident inspector and licensee
representatives identified in paragraph 1 on October 8, 1987, and
