2. Licensee Actions on Previous Inspection Findings | |||
(0 pen) Open Item (482/8515-01): Ruskin Fire Dampers: The licensee's | |||
testing and rework of the Ruskin fire dampers has not been completed. By | |||
g letter dated May 1, 1985, the licensee made a 10 CFR Part 21 Report to the | |||
NRC Region IV office concerning the installation of some of the fire | |||
' | |||
i dampers with less than the designed clearance between the fire damper | |||
' frame and the penetration sleeve. This insufficient clearance could cause | |||
the fire damper to warp and become inoperative during a fire. This item | |||
will remain open. | |||
i (Closed) Open Item (482/8511-08): This item involved Preoperational Test | |||
Deficiency Deferral (RO) #40 concerning retesting of a condensate | |||
' | |||
i. demineralizer outlet sample throttling valve following rework. The NRC | |||
l inspector reviewed appropriate test documentation including Work Request | |||
(WR) 14140-84 and found test data for the reworked valve acceptable. | |||
(Closed) Open Item (482/8511-13): This item involved RD #61 concerning an | |||
inability to perform Section 7.8 of Test SU3-HA01 due to equipment | |||
problems with the hydrogen and oxygen analyzers in the purge line from the | |||

volume control tank (VCT) to the gaseous radwaste system. The licensee | |||
t | |||
requested and the NRC granted an extension of the completion of this item | |||
from prior to Mode 4 entry to prior to Mode 2 entry. The analyzers as | |||
presently installed meet Technical Specifications (TS) requirements due to | |||
their ability to be operated in manual; however, due to equipment procure- | |||
ment problems they are not presently able to be run in automatic which | |||
would be required in order to clear the test deficiencies. This section | |||
of the test can be deferred until prior to entry into Mode 2 for the | |||
reasons stated above. This will be tracked as an open item. (482/8519-03) | |||
(Closed) Open Item (482/8511-04): This item involved installation of the | |||
essential service water chlorination system prior to Mode 4. The NRC | |||
' inspector walked down parts of the installed chlorination system, | |||
questioned plant operators on the operability of the chlorination system, | |||
reviewed Interim Design Change Package (IDCP) M-142KT, reviewed Field | |||
Change Work Plan 1-FJ-108-034, reviewed Field Change Request | |||
(FCR) 1-0303-H, and reviewed WRs on the installation and testing of the | |||
chlorination system. | |||
(Closed) Open Item (482/8511-21): This item involved RD #65 concerning | |||
computer calculation problems of. determining leakage rates into the | |||
auxiliary building and residual heat removal pump room (RHR) sumps. The | |||
NRC inspector reviewed the documentation of the retest to SU3-88158, Test | |||
Deficiency Reports (TDR) 01 and 02 and found it acceptable. | |||
(Closed) Open Item (482/8511-14): This item involved RD #66 concerning- | |||
computer calculation problems of determining leakage rates into the | |||
containment normal sumps. The NRC inspector reviewed the documentation of | |||
the retest to 503-B8158, TDR-04 to the Test Deficiencies (TD) 010 and 017 | |||
and found it acceptable. | |||
(Closed) Open Item (482/8511-07): This item involved completion of the | |||
reapplication of the concrete coatings removed on the 2000' elevations of | |||
containment as a result of 10 CFR 50.55(e) Report TE53564-K159. After the | |||
NRC inspector was informed by the licensee, the reapplication was | |||
complete, he toured the 2000' elevation of containment and reviewed | |||
appropriate WRs and found them acceptable. | |||
(Closed) Open Item (842/8427-06): This item tracked licensee evaluation | |||
of excess reactor coolant pump (RCP) seal leakage on the Number 1 seals of | |||
C and D RCPs This evaluation was performed. It concluded that the seal | |||
surfaces had rubbed, but no cause could be definitely established. | |||
Foreign material contamination was ruled out. The seals were replaced and | |||
performed satisfactorily. This item was incorrectly referenced as | |||
482/8427-01 in Inspection Report 50-482/85-04. | |||

- | |||
50-482/85-004-00 - Technical Specifications violation | |||
- | |||
50-482/85-005-00 - Technical Specifications violation | |||
Unless otherwise noted below, the NRC inspector had no comments, | |||
d. During April, the licensee had three safety injections (SI). All | |||
were inadvertent and due to low steam line pressure signals. The | |||
following is a list of the dates, times, and modes in which they | |||
occurred: | |||
1. April 19, 1985 16:19 CST Mode 4 | |||
2. April 28, 1985 15:50 CDT Mode 3 | |||
3. April 30, 1985 11:43 CDT Mode 3 | |||
The resident inspector was onsite during the three sis and responded | |||
to the control room as soon as he was notified. The NRC inspector | |||
verified the licensee had responded in accordance with procedures and | |||
notified the necessary agencies and personnel in a timely fashion. | |||
The plant operators responded to the sis in a calm, deliberate, and | |||
knowledgeable manner. During tne' April 28, 1985 SI, approximately 2 | |||
hours after the event, the NRC inspector was performing a detailed | |||
review of all control room panels when he observed Annunciator F-79, | |||
" Loose Parts Monitor" energized. Upon questioning the supervising | |||
operator, the NRC inspector learned that the annunciator had been | |||
acknowledged without any control room personnel being aware it had | |||
"come in". An operator was sent to the loose parts monitor panel and | |||

reported a signal on Channel'2. ' Operations requested reactor | |||
engineering personnel to investigate, and.it was verified that the | |||
-noise was being heard on Channels.1, 2, and 4. At this time, the | |||
noise ~is a high frequency, low amplitude type which is indicative of | |||
an object with a small mass or one which is restrained. The failure | |||
- | |||
to follow Alarm Procedure ALR 00-0079F is a violation. | |||
(50-482/8519-02) | |||
e. .During this inspection the NRC inspector also followed up on the | |||
following engineered safety features actuation events: | |||
1. ; April 7, 1985 10:38 CST Mode 5 Control Room Ventilation | |||
Isolation (CRVIS) and Fuel | |||
Building Isolation (FBIS) | |||
2. April 8, 1985 08:47 CST Mode 5 CRVIS | |||
3. . April 9, 1985 14:06 CST Mode 5 Containment Purge Isolation | |||
(CPIS) and CRVIS | |||
4. April 12, 1985 22:15 CST Mode 5 CRVIS | |||
5. April 12,~ 1985 11:14 CST Mode 5 FBIS, CPIS, and CRVIS | |||
6.- April 21, 1985 19:22 CST Mode 4 CRVIS | |||
; 7. April 26, 1985 18:54 CST Mode 3 Feedwater Isolation (FWIS) | |||
and Auxiliary Feedwater | |||
Actuation (AFAS) | |||
f. On April 10, 1985, at approximately 1555 hours CST the central alarm | |||
station (CAS) operator identified a problem with Door 31042-(access | |||
from health physics area to auxiliary building) and dispatched an | |||
, officer to.that location. Upon arrival, the officer found 10 to 15 | |||
individuals waiting for. access through the door. Apparently, no one | |||
had identified an access problem to security. A number of | |||
individuals had apparently entered the auxiliary building when other | |||
individuals exited as the card reader had not been operating | |||
-properly. The_CAS operator dispatched an officer to the scene after | |||
several individuals had requested computer overrides to allow then to | |||
exit the auxiliary building. | |||
The CAS operator incorrectly assumed the locking mechanism was not | |||
operating properly, when the dispatched officer could not' gain access | |||
through the door, and placed it in access.. He directed the officer | |||
to ensure everyone was'using the card reader. Approximately 20 | |||
minutes later, a second CAS operator decided the card reader was | |||
inoperable and directed the officer at the scene to initiate a manual | |||
~ | |||
access log. All personnel who had entered the auxiliary building | |||
i during this incident were identified and found to have access | |||
; authorization. | |||
The NRC inspector discussed with the plant superintendent the | |||
, apparent slow response in discovering the problem and lack of | |||
: training and/or concern for security. The plant superintendent I | |||
{ stated that he would have al1~ individuals involved in the incident | |||
[. interviewed to determine why they had not contacted security when | |||
l they were having access problems. | |||

5. Startup Test Witnessing and Observation | |||
The NRC inspectors observed portions of the following startup tests: | |||
- | |||
- | |||
SU7-SF03.1 - Cold No Flow Control Rod System Testing | |||
- | |||
SU7-SF03.2 - Cold Full Flow Control Rod System Testing | |||
SU7-SR03 - Incore Movable Detector Test | |||
- | |||
SU7-0015 - Power Ascension Thermal and Dynamic Test | |||
- | |||
- | |||
SU8-BB13 - Pressurizer Relief Valve Test | |||
STS-PE19 - Reactor Coolant System Isolation Valve Leakage | |||
The NRC inspectors verified conformance by the licensee to procedural and | |||
license requirements, observed the performance of the plant operating | |||
staff and verified the adequacy of test program records, including | |||
preliminary evaluation of the test results. | |||
No violations or deviations were identified. | |||
6. Precritical Testing Data Review | |||
The NRC inspectors reviewed the following completed test procedures to | |||
ascertain compliance with administrative and test procedures and | |||
conformance to Final Safety Analysis Report (FSAR) and Technical | |||
Specifications requirements: | |||
- | |||
- | |||
SU7-0001 - Initial Core Loading | |||
SU7-0002 - Inverse Count Rate Ratio Monitoring For Core Loading | |||
- | |||
5U7-5009 - Initial Core Loading | |||
- | |||
SU7-SE02.1 - Operational Alignment Of Nuclear Instrumentation | |||
- | |||
SU7-SC01 - Core Loading Instrumentation and Neutron Source | |||
Requirements | |||
- | |||
SU7-SR03 - Incore Movable Detector Test | |||
Selected NRC inspector comments are noted below: | |||
During the review of SU7-5009, the inspector noted that steps 4.1, " Core | |||
loading operations shall be suspended, pending evaluation by the senior | |||
reactor operator (SRO) in charge of refueling, who has no concurrent | |||
responsibilities, and reactor engineering personnel, if any of the | |||
following conditions occur during core loading" and 4.1.8 "Less than two | |||
, | |||
' of the nuclear channels being used for inverse count rate ratio ICRR | |||
monitoring have counting rates greater than or equal to 2 counts per | |||
second (af ter both primary source-bearing assemblies are loaded in the | |||
vessel and completion of core loading step 10)" were written so as to be | |||
vague enough to allow test and operations personnel to exceed the | |||
i limitations desired by the plant safety review committee (PSRC) and the | |||
Plant Manager. Although this did not occur during the performance of this | |||
test, the inspectors concern was that it could happen during a future | |||
refueling operation. The licensee stated that this statement was not in | |||
l | |||
L | |||
r _- | |||
. | |||
> | |||
-9- | |||
the procedure to be used for the refueling operation and they committed | |||
that if they wanted to place it in that procedure, appropriate limitations | |||
and precautions would be taken. All NRC inspector concerns with this | |||
procedure have been resolved. | |||
No violations or deviations were identified. | |||
7. Plant Tours | |||
Control room activities were observed on a regular basis including several | |||
shift turnovers. Special emphasis was placed on verifying implementation | |||
of administrative controls for fire protection, temporary modifications, | |||
and out of-service equipment. Compliance with TS and limiting conditions | |||
for operations were verified as appropriate. | |||
The NRC inspector observed that although WCGS Administrative Procedure ADM | |||
13-102, Rev. 4, requires an expiration date for combustible materials | |||
permits in step 5.2.1, the form in use does not have a block for this i | |||
date. The Superintendent of Plant Support committed to making the ' | |||
procedure and form compatible. This will be tracked as an open item. | |||
(482/8519-03) | |||
On April 2, 1985, the NRC inspector noted the following unusual | |||
indications which he discussed with the supervising operator: | |||
- | |||
345 Kv west bus indicating light was blinking | |||
- | |||
No status lights were illuminated for Breaker 69-16 | |||
The supervising operator stated that these conditions would be promptly | |||
corrected or work requests would be issued and the indicating lights | |||
status tagged. The NRC inspector verified that this had been | |||
accomplished. | |||
No violations or deviations were identified. | |||
8. Document Control | |||
The NRC inspector conducted an audit of WCGS Procedure Manuals and | |||
Drawings located in the TSC and EOF on April 10 and 11, 1985, in response | |||
to expressed concerns. Documents surveyed were randomly selected from the | |||
KG&E master drawing file index and the computer based master procedure | |||
index. Sixteen drawings were selected and the correct revision levels | |||
were found at either location. Of 46 procedures selected, the NRC | |||
inspector identified problems with nine at the TSC and fifteen at the EOF | |||
as follows: | |||

2. Licensee Actions on Previous Inspection Findings
(0 pen) Open Item (482/8515-01): Ruskin Fire Dampers: The licensee's
testing and rework of the Ruskin fire dampers has not been completed. By
g letter dated May 1, 1985, the licensee made a 10 CFR Part 21 Report to the
NRC Region IV office concerning the installation of some of the fire
'
i dampers with less than the designed clearance between the fire damper
' frame and the penetration sleeve. This insufficient clearance could cause
the fire damper to warp and become inoperative during a fire. This item
will remain open.
i (Closed) Open Item (482/8511-08): This item involved Preoperational Test
Deficiency Deferral (RO) #40 concerning retesting of a condensate
'
i. demineralizer outlet sample throttling valve following rework. The NRC
l inspector reviewed appropriate test documentation including Work Request
(WR) 14140-84 and found test data for the reworked valve acceptable.
(Closed) Open Item (482/8511-13): This item involved RD #61 concerning an
inability to perform Section 7.8 of Test SU3-HA01 due to equipment
problems with the hydrogen and oxygen analyzers in the purge line from the

1
volume control tank (VCT) to the gaseous radwaste system. The licensee
t
requested and the NRC granted an extension of the completion of this item
from prior to Mode 4 entry to prior to Mode 2 entry. The analyzers as
presently installed meet Technical Specifications (TS) requirements due to
their ability to be operated in manual; however, due to equipment procure-
ment problems they are not presently able to be run in automatic which
would be required in order to clear the test deficiencies. This section
of the test can be deferred until prior to entry into Mode 2 for the
reasons stated above. This will be tracked as an open item. (482/8519-03)
(Closed) Open Item (482/8511-04): This item involved installation of the
essential service water chlorination system prior to Mode 4. The NRC
' inspector walked down parts of the installed chlorination system,
questioned plant operators on the operability of the chlorination system,
reviewed Interim Design Change Package (IDCP) M-142KT, reviewed Field
Change Work Plan 1-FJ-108-034, reviewed Field Change Request
(FCR) 1-0303-H, and reviewed WRs on the installation and testing of the
chlorination system.
(Closed) Open Item (482/8511-21): This item involved RD #65 concerning
computer calculation problems of. determining leakage rates into the
auxiliary building and residual heat removal pump room (RHR) sumps. The
NRC inspector reviewed the documentation of the retest to SU3-88158, Test
Deficiency Reports (TDR) 01 and 02 and found it acceptable.
(Closed) Open Item (482/8511-14): This item involved RD #66 concerning-
computer calculation problems of determining leakage rates into the
containment normal sumps. The NRC inspector reviewed the documentation of
the retest to 503-B8158, TDR-04 to the Test Deficiencies (TD) 010 and 017
and found it acceptable.
(Closed) Open Item (482/8511-07): This item involved completion of the
reapplication of the concrete coatings removed on the 2000' elevations of
containment as a result of 10 CFR 50.55(e) Report TE53564-K159. After the
NRC inspector was informed by the licensee, the reapplication was
complete, he toured the 2000' elevation of containment and reviewed
appropriate WRs and found them acceptable.
(Closed) Open Item (842/8427-06): This item tracked licensee evaluation
of excess reactor coolant pump (RCP) seal leakage on the Number 1 seals of
C and D RCPs This evaluation was performed. It concluded that the seal
surfaces had rubbed, but no cause could be definitely established.
Foreign material contamination was ruled out. The seals were replaced and
performed satisfactorily. This item was incorrectly referenced as
482/8427-01 in Inspection Report 50-482/85-04.

-
50-482/85-002-00 - Technical Specifications violation
-
50-482/85-003-00 - Engineered safety feature actuation

-
50-482/85-005-00 - Technical Specifications violation
Unless otherwise noted below, the NRC inspector had no comments,
d. During April, the licensee had three safety injections (SI). All
were inadvertent and due to low steam line pressure signals. The
following is a list of the dates, times, and modes in which they
occurred:
1. April 19, 1985 16:19 CST Mode 4
2. April 28, 1985 15:50 CDT Mode 3
3. April 30, 1985 11:43 CDT Mode 3
The resident inspector was onsite during the three sis and responded
to the control room as soon as he was notified. The NRC inspector
verified the licensee had responded in accordance with procedures and
notified the necessary agencies and personnel in a timely fashion.
The plant operators responded to the sis in a calm, deliberate, and
knowledgeable manner. During tne' April 28, 1985 SI, approximately 2
hours after the event, the NRC inspector was performing a detailed
review of all control room panels when he observed Annunciator F-79,
" Loose Parts Monitor" energized. Upon questioning the supervising
operator, the NRC inspector learned that the annunciator had been
acknowledged without any control room personnel being aware it had
"come in". An operator was sent to the loose parts monitor panel and

reported a signal on Channel'2. ' Operations requested reactor
engineering personnel to investigate, and.it was verified that the
-noise was being heard on Channels.1, 2, and 4. At this time, the
noise ~is a high frequency, low amplitude type which is indicative of
an object with a small mass or one which is restrained. The failure
-
to follow Alarm Procedure ALR 00-0079F is a violation.
(50-482/8519-02)
e. .During this inspection the NRC inspector also followed up on the
following engineered safety features actuation events:
1. ; April 7, 1985 10:38 CST Mode 5 Control Room Ventilation
Isolation (CRVIS) and Fuel
Building Isolation (FBIS)
2. April 8, 1985 08:47 CST Mode 5 CRVIS
3. . April 9, 1985 14:06 CST Mode 5 Containment Purge Isolation
(CPIS) and CRVIS
4. April 12, 1985 22:15 CST Mode 5 CRVIS
5. April 12,~ 1985 11:14 CST Mode 5 FBIS, CPIS, and CRVIS
6.- April 21, 1985 19:22 CST Mode 4 CRVIS
Actuation (AFAS)
f. On April 10, 1985, at approximately 1555 hours0.018 days <br />0.432 hours <br />0.00257 weeks <br />5.916775e-4 months <br /> CST the central alarm
station (CAS) operator identified a problem with Door 31042-(access
from health physics area to auxiliary building) and dispatched an
, officer to.that location. Upon arrival, the officer found 10 to 15
individuals waiting for. access through the door. Apparently, no one
had identified an access problem to security. A number of
individuals had apparently entered the auxiliary building when other
individuals exited as the card reader had not been operating
-properly. The_CAS operator dispatched an officer to the scene after
several individuals had requested computer overrides to allow then to
exit the auxiliary building.
The CAS operator incorrectly assumed the locking mechanism was not
operating properly, when the dispatched officer could not' gain access
through the door, and placed it in access.. He directed the officer
to ensure everyone was'using the card reader. Approximately 20
minutes later, a second CAS operator decided the card reader was
inoperable and directed the officer at the scene to initiate a manual
~
access log. All personnel who had entered the auxiliary building
i during this incident were identified and found to have access
- authorization.
The NRC inspector discussed with the plant superintendent the
, apparent slow response in discovering the problem and lack of
- training and/or concern for security. The plant superintendent I
{ stated that he would have al1~ individuals involved in the incident
[. interviewed to determine why they had not contacted security when
l they were having access problems.

5. Startup Test Witnessing and Observation
The NRC inspectors observed portions of the following startup tests:
-
-
SU7-SF03.1 - Cold No Flow Control Rod System Testing
-
SU7-SF03.2 - Cold Full Flow Control Rod System Testing
SU7-SR03 - Incore Movable Detector Test
-
SU7-0015 - Power Ascension Thermal and Dynamic Test
-
-
SU8-BB13 - Pressurizer Relief Valve Test
STS-PE19 - Reactor Coolant System Isolation Valve Leakage
The NRC inspectors verified conformance by the licensee to procedural and
license requirements, observed the performance of the plant operating
staff and verified the adequacy of test program records, including
preliminary evaluation of the test results.
No violations or deviations were identified.
6. Precritical Testing Data Review
The NRC inspectors reviewed the following completed test procedures to
ascertain compliance with administrative and test procedures and
conformance to Final Safety Analysis Report (FSAR) and Technical
Specifications requirements:
-
-
SU7-0001 - Initial Core Loading
SU7-0002 - Inverse Count Rate Ratio Monitoring For Core Loading
-
5U7-5009 - Initial Core Loading
-
SU7-SE02.1 - Operational Alignment Of Nuclear Instrumentation
-
SU7-SC01 - Core Loading Instrumentation and Neutron Source
Requirements
-
SU7-SR03 - Incore Movable Detector Test
Selected NRC inspector comments are noted below:
During the review of SU7-5009, the inspector noted that steps 4.1, " Core
loading operations shall be suspended, pending evaluation by the senior
reactor operator (SRO) in charge of refueling, who has no concurrent
responsibilities, and reactor engineering personnel, if any of the
following conditions occur during core loading" and 4.1.8 "Less than two
,
' of the nuclear channels being used for inverse count rate ratio ICRR
monitoring have counting rates greater than or equal to 2 counts per
second (af ter both primary source-bearing assemblies are loaded in the
vessel and completion of core loading step 10)" were written so as to be
vague enough to allow test and operations personnel to exceed the
i limitations desired by the plant safety review committee (PSRC) and the
Plant Manager. Although this did not occur during the performance of this
test, the inspectors concern was that it could happen during a future
refueling operation. The licensee stated that this statement was not in

the procedure to be used for the refueling operation and they committed
that if they wanted to place it in that procedure, appropriate limitations
and precautions would be taken. All NRC inspector concerns with this
procedure have been resolved.
No violations or deviations were identified.
7. Plant Tours
Control room activities were observed on a regular basis including several
shift turnovers. Special emphasis was placed on verifying implementation
of administrative controls for fire protection, temporary modifications,
and out of-service equipment. Compliance with TS and limiting conditions
for operations were verified as appropriate.
The NRC inspector observed that although WCGS Administrative Procedure ADM
13-102, Rev. 4, requires an expiration date for combustible materials
permits in step 5.2.1, the form in use does not have a block for this i
date. The Superintendent of Plant Support committed to making the '
procedure and form compatible. This will be tracked as an open item.
(482/8519-03)
On April 2, 1985, the NRC inspector noted the following unusual
indications which he discussed with the supervising operator:
-
345 Kv west bus indicating light was blinking
-
No status lights were illuminated for Breaker 69-16
The supervising operator stated that these conditions would be promptly
corrected or work requests would be issued and the indicating lights
status tagged. The NRC inspector verified that this had been
accomplished.
No violations or deviations were identified.
8. Document Control
The NRC inspector conducted an audit of WCGS Procedure Manuals and
Drawings located in the TSC and EOF on April 10 and 11, 1985, in response
to expressed concerns. Documents surveyed were randomly selected from the
KG&E master drawing file index and the computer based master procedure
index. Sixteen drawings were selected and the correct revision levels
were found at either location. Of 46 procedures selected, the NRC
inspector identified problems with nine at the TSC and fifteen at the EOF
as follows:
a. TSC
