Emergency Response Facility Appraisal.0 pen Items (992078)
This section addresses the status of corrective actions implemented by the
licensee in response to Open Items identified during the referenced
appraisal.
The bracketed numbers in the following paragraphs correspond
to the items assigned in Appendix B to the letter of December 23, 1985,
- which transmitted NRC Report Nos. 50-413/85-39 and 50-414/85-36.
All
items identified herein which remain open, will be reviewed during
subsequent inspections,
a.
[1]
(Closed) Open Item (50-413/85-39-08, 50-414/85-36-03):
Installation of a separate Technical Support Center (TSC) Operator
Aid Computer (0AC) alarm video.
The-inspector concurred with the
licensee's finding that, based upon a cost-benefit analysis, the need
for a separate OAC alarm did not warrant current implementation.
It
was noted, however, that this item would be factored into future
review and evaluation of TSC computer equipment and needs.
b.
[2]
(Closed) Open Item (50-413/85-39-09, 50-414/85-36-09):
Evaluation of the licensee's response to the Technical Evaluation
Report (TER) regarding radiation monitoring.
This item and
exceptions related thereto was treated in Supplement V to the Catawba
SER of February 1986.
c.
[3] (0 pen)OpenItem(50-413/85-39-10,50-414/85-36-10): Correction
of the transfer of TSC-0AC data to the VAX computer to preclude
airborne contamination of personnel involved therein during possible
emergency condition.
An inspector reviewed the ventilation system
arrangement to the OAC Computer Room and noted that a positive
pressure is maintained in the room.
Note, however, that under
certain airborne radiological accidents, the outside air supply
'
providing the positive pressure would either be manually isolated
(loss of positive pressure) or would become the source of airborne
activity.
The basis for the finding was unchanged, and the inspector
concluded that this item remained open.
d.
[4]
_(Closed) Open Item (50-413/85-39-11, 50-414/85-36-11):

Emergency Response Facility Improvement Items (990278)
This section addresses the status of corrective actions implemented by the
licensee in response to Improvement Items identified during the referenced
appraisal.
The bracketed numbers in the following paragraphs correspond
to the items assigned in Appendix C to the letter of December 23, 1985,
which transmitted NRC Report Hos. 50-413/85-39 and 50-414/85-36.
All
items identified herein which remain open will be reviewed during
subsequent inspections,
a.
[1]
(Closed) Improvement Item (50-413/85-39-01, 50-414/85-36-01):
,
Moving the Emergency Coordinator's station to a centralized location
within the Technical Support Center (TSC) to enhance his interaction
with the staff, and provide viewing of the facility's status boards
and displays.
Inspection disclosed that the current location of the
Emergency Coordinator's station offers no impediment to required
conduct of TSC operations.
b.
[2]
(Closed) Improvement Item (50-413/85-39-02, 50-414/85-35-02):
Using a different technique to alert control room operators that
core temperature data is outside of the expected range.
Inspection
disclosed that 0AC program modifications which perform " range within
limits" validation checks of core-exit thermocouples (CET's) have
'
been completed.
Range of CET's is compared to parameters such as
power and coolant average temperature, and if out-of-range relative
to these parameters, then alerting of operators is performed.
off-normal readings are now related to abnormal core condition.
c.
[3]
(Closed) Improvement Item (50-413/85-39-03, 50-414/85-36-03):
Identifying core temperature functions separately on the displays.
Inspection disclosed that 0AC program modifications which perform
,
validation checks of core-exit thermocouple (CET) readouts have been
i
completed.
Additionally, the validated values are used for other-
functions, such as SPDS, wFere the five highest CETs are averaged.
'
,
)
.
_ . -
.,
,
.

Since the readouts are validated before usage, the inspector
concluded that no separate identification of CET functions was
required,
d.
[0]
(0 pen) Improvement Item: Update Data Acquisition Systems from
the plant to the Technical Support Center (TSC) and the Crisis
Management Center (CMC).
All Improvement Items listed below relate
directly or indirectly to the facility data acquisition system and
are therefore included under this summary item.
As indicated, all
items hereunder are open and collectively discussed in the
commentary.
[4]
(0 pen) Improvement Item (50-413/85-39-04,, 50-414/85-36-04):
'
Validating Operator Aid Computer (OAC) data through use of
appropriate software algorithms.
[5] (0 pen) Improvement Item (50-413/85-39-05, 50-414/85-36-05):
Automating the present manual transfer of data from the OAC-VAX
computers, providing the VAX with continuous access to data at, or
near, real time.
[19] (0 pen) Improvement Item (50-413/85-39-28, 50-414/85-36-28):
Providing the CMC with a continuous computer data input at, or near,
real-time.
[20] (0 pen) Improvement Item (50-413/85-39-30, 50-414/85-36-30):
Standardizing Catawba Station data sets to include all Regulatory
Guide 1.97 parameters in the standard format.
[21](0 pen) Improvement Item (50-413/85-39-31, 50-414/85-36-31):
Improving the method of data transmission to the CMC such that the
data is real-time, or near real-time.
-
An inspector reviewed the current status of the data Acquisition
System for collection, storage, analysis, display, and communication
of plant parameters.
It was determined that the system attributes
were essentially the same as those that existed at the time of the
appraisal in September 1985.
Consistent with the Improvement Items
listed above, the following considerations are indicated, namely:
Validating 0AC data with computer-based algorithms.
Automating data transfer from the OAC to the VAX computer system
to provide continuous data access at, or near, real-time.
Provision of a data stream to the TSC and CMC at, or near,
real-time.
Assure that the data stream to the TSC and CMC include
Regulatory Guide 1.97 variables as a minimum.
.
__
.
.
7
The inspector also determined, however, that the licensee was
actively pursuing implementation of an interim system and a "new"
system.
The interim system will eliminate the mannual data transfer
from the OAC to the VAX computers (" floppy disk transfer"). The new
system (early 1988) will embrace the other desired attributes of
validation, auto-transmission, and all accident parameters being
available.
However, the licensee currently envisions an up-date
frequency of three to five minutes for each data set. This frequency
may not be consistent with NRC goals of "real-time or near real
time." These items will be reviewed during subsequent inspections,
e.
[6] (Closed) Improvement Item (50-413/85-39-06, 50414/85-36-06):
Designating personnel with required expertise to operate the OAC
terminal, as part of the TSC response team, or improving the OAC
interface to assure that casual users can more easily understand its
-operation. Although the subject system is not user-friendly, inspection
disclosed that .the licensee has provided a cadre of trained 0AC
computer operators who are readily available and present on all
operating shifts.
f.
[7] (Closed) Improvement Item (50-413/85-39-07, 50-414/85-36-07):
Changing the OAC terminal keyboards, positioned in a nearly vertical
orientation, to an ergonomically correct position to minimize
mis-keying.
Inspection disclosed that the curtant mounting of the
OAC terminal keyboards pose no significant Impediment or delay to
access of desired data.
g.
[8] (0 pen) Improvement Item (50-413/85-39-12, 50-414/85-36-12):
Revising Section 5.6 of Procedure HP/0/8/1009/15 to provide adequate
instructions, and upgrading and clarifying containment leak rate
curves.
An inspector reviewed the referenced procedure and noted
that no revisions were made that corrected observed procedural
problems.
The inspector noted, however, that ERP HP/0/B/1009/18,
"Offsite Dose Projection", supercedes (and corrects) HP/0/B/1009/15.
The licensee intends to cancel HP/0/B/1009/15 following completion of
implementation of 1009/18.
h.
[9] (Closed) Improvement Item (50-413/85-39-14, 50-414/85-36-14):
Conducting an evaluation of the quality of meteorological data
obtained from the National Weather Station (NWS) at Charlotte, and/or
the McGuire Nuclear Station meteorological facility for real-time
conditions at Catawba. The evaluation appeared to utilize acceptable
statistical and analytical concepts.
The licensee's findings
included the following:
Wind Direction Data at McGuire NS or the NWS Charlotte Airport
yields distributions of direction differences with too much
scatter to reliably estimate wind direction at Catawba NS.

Wind' Speed Data from Charlotte Airport yield wind speed twice
that at Catawba NS. Thus, Catawba wind speed equals one-half of
the NWS Charlotte Airport wind speed..
Data from McGuire Station yields an acceptable substitute for
wind speed at Catawba Station.
,
Temperature Difference - The NWS Charlotte Airport can not
provide temperature difference data.
.
'
Data at McGuiri Station yields distribution of . temperature
differences with too much scatter to reliably estimate the
,
temperature difference at Catawba.

1.
[10] (0 pen) Improvement Item (50-413/85-39-15, 50-414/85-36-15):
i
Revising procedures which use meteorological data to reflect the
hierarchy for data substitution, and specifying an' assigned data '
!
averaging period
(i.e.,
15 minutes) and valid time of the
observation.
Specifying averaging period _ and valid time of the
observation for the digital displays or sumary ' sheets provided
>
through the VAX computer.
The initial response of the licensee
'
,
(letter dated June 6, 1986)-to this item was subsequently revised in
l
a letter dated June 15, 1986.
The inspector confirmed that the
appropriate procedures (HP/0/B/1009/13 and HP/0/8/1009/15) have been-
revised to detail the hierarchy of data substitution and specifying
an assigned data averaging period.
The hierarchy established,
however, is not consistent with the findings of the study performed
by the licensee in response to Catawba Item [9].
For example, the
revised procedures require that if the wind speed at the Catawba
facility is not available, the data should be_ obtained from the NWS,
'
Charlotte Airport.
However, the study concluded that the win'd speed
,
at the Charlotte Airport is-not a suitable substitute for the Catawba
'
Station.
This item will remain open until the discrepancy is
resolved.

Identifying regional and forecast meteorological information to be
i
provided on request by the National Weather Service Station in
i
Charlotte.
The licensee maintains a staff of professional
meteorologists and routinely receives meteorological ~ data from NOAA.
It appears that the licensee's expertise in this field permits its
staff to adequately provide regional and forecast meteorological data
,
during an emergency.
