On July 24,1986 the plant was shut down to Mode 3 to repair a stator | |||
cooling water leak in the main generator. During the controlled | |||
shutdown, the reactor tripped.at approximately 13 percent power due to a | |||
1o-10 steam generator water level condition. The plant was returned to | |||
Mode 1 on July 26, 1986. | |||
3. Followup on Previously Identified NRC Items | |||
(Closed) Violation (482/8526-02): Temporary changes not incorporated in | |||
procedure as required. | |||
The NRC inspector verified by review that the licensee's surveillance | |||
procedure cover sheet has been revised to require that the test | |||
performer verify that the latest revision of the surveillance test is | |||
being used. This item is closed. | |||
(Closed) Violation (482/8535-05): Failure to follow housekeeping | |||
requirements. | |||
The licensee took immediate action and cleaned up the areas which | |||
created the housekeeping concerns identified in this violation. On | |||
subsequent walkdowns, the NRC inspectors have observed that housekeeping | |||
was being maintained as required. This violation is closed. | |||
(Closed) Violation (482/8538-01): Failure to establish procedures for | |||
certain activities that could affect the performance of safety-related | |||
equipment. | |||
The NRC inspector, by review of documents and plant walkdowns, verified | |||
the following licensee actions related to this violation: | |||
o Section 5.3.2 of Administrative Procedure ADM 01-034, Revision 8, | |||
" Housekeeping and Cleanliness Control," has been revised to state | |||
that hoist hooks shall be fully raised and ladders returned to | |||
their designated storage location. | |||
l | |||
0 Permanent storage brackets for ladders have been installed at | |||
seventeen locations in the plant and have been identified by signs. | |||
i | |||
o Storage of ladders was discussed at the safety committee meeting | |||
held on April 2, 1986. Safety meetings were used to train | |||
employees in the use of ladders. | |||
During subsequent plant walkdowns, the NRC inspectors have not | |||
identified any further instances where ladders and hoists could have | |||
^ | |||
affected the operation of safety-related equipment. This violation is | |||
closed. | |||

The NRC inspector reviewed the letter which was issued to all | |||
organizations which may be called upon to perfonn work in the plant and | |||
verified that it was discussed with the appropriate personnel. In addition, | |||
since this violation was first identified no other similar violations | |||
have been discovered. This violation is closed. | |||
(Closed) Violation (482/8530-01): Test port not reclosed in accordance | |||
with procedure. | |||
The NRC inspector reviewed five randomly selected procedures which | |||
remove plugs in HVAC test ports and verified the procedures included | |||
clear requirements to reinstall plugs in test ports. In addition, field | |||
inspections by NRC inspectors have failed to identify any similar | |||
violations to date. This violation is closed. | |||
(Closed) Violation (482/8530-02): Inadequate procedure. | |||
The NRC inspector reviewed STS IC-275A and STS IC-275B and verified that | |||
the requirement for damper movement had been removed. In addition, the | |||
sample results of the containment atmosphere drawn at 2100 CST on | |||
July 26, 1985, was reviewed for abnormal results. This violation is | |||
closed. | |||
4. Review of Licensee Event Reports | |||
During this inspection period, the NRC inspectors performed followup on | |||
selected Wolf Creek LERs. The LERs were reviewed to ensure: | |||
o The corrective action stated in the report has been properly | |||
completed. | |||
o Responses to the events were adequate. | |||
o Responses to the events met license conditions, commitments, or | |||
other applicable regulatory requirements. | |||
o The information contained in the report satisfied applicable | |||
reporting requirements. | |||
o That any generic issues were identified, | |||
o The report conformed to the guidelines contained in NUREG-1022 and | |||
Supplements 1 and 2. | |||
The following LERs were reviewed and closed. | |||

~ | |||
'" Instructions Describing Reportability, Review, and Documentation | |||
of Licensee Event Reports (LERs), and Defect Deficiencies," | |||
' | |||
Revision 15, were reviewed for agreement with LER reporting | |||
requirements, | |||
r | |||
o In general, the quality and adequacy of the licensee's LERs has | |||
~ | |||
been improving. However, minor deficiencies were noted in the LER | |||
information requirements. For example, five out of six LERs | |||
, | |||
reviewed did not discuss whether any previous similar events at the | |||
i | |||
plant were known to.the licensee. These deficiencies were | |||
discussed with the licensee during this inspection period. | |||
o During an inspection of control room area radiation monitor | |||
instrunentation and chart recorders while following up on LER | |||
; | |||
482/86-019-00, the NRC inspector noted that Chart Recorder GT RR-58, | |||
t " Unit Ventilation Effluent Release Rate," and GH RR-51, "Radwaste | |||
Building Effluent Release Rate," were not scaled, but did have a tag | |||
saying 0 to 100. None of the licensed operators questioned knew | |||
what units the chart recorders used. Instrumentation and control | |||
informed the NRC inspector that the chart recorders were calibrated | |||
j from 10E1 to 10E13 micro Ci/sec. The licensee committed to install | |||
i | |||
the correct scales. | |||
: ' | |||
l o -0n July 18,1986,'during a review of completed surveillances | |||
related to LER 482/86-033-00, the NRC inspector observed that | |||
, | |||
STS CH-008A, " Emergency Diesel Fuel Storage Tank," performed on | |||
June 1, 1986, was Revision 3 and that the data sheet for STS CH-0088, | |||
, " Emergency Diesel Fuel Storage Tank," had been used. The plant safety | |||
l review conmittee (PSRC) document control records showed that | |||

STS CH-C08A, Revision 4 had been issued on May 14, 1986. The | |||
records review indicated that the appropriate tank was sampled and | |||
that the sample data met the TS criteria. This failure of the test | |||
performer to use the correct procedure and revision, even though he | |||
had signed off in Section 1 of the cover sheet that he had used the | |||
correct procedure and revision, and failure of the surveillance | |||
ost-performance review cycle to discover this error is a violation. | |||
482/8617-01) | |||
5. Operational Safety Verification | |||
The NRC inspectnrs verified that the facility is being operated safely | |||
and in conformance'with regulatory requirements by direct observation of | |||
> | |||
licensee facilities, tours of the facility, interviews and discussions | |||
with licensee personnel, independent verification of safety system | |||
status and limiting conditions for operations, and reviewing facility | |||
records. The NRC inspectors, by observation and direct interview, | |||
verified the physical security plan was being implemented in accordance | |||
with the security plan and that radiation protection activities were | |||
controlled. | |||
By observing . valve position, electrical breaker position, and control | |||
room indication, the NRC inspectors confirmed the operability of the | |||
residual heat removal system and the emergency diesel generators. | |||
The NRC inspectors also visually inspected safety components for | |||
leakage, physical damage, and other impairments that could prevent them | |||
from performing their designed function. | |||
No violations or deviations were identified. | |||
6. Engineered Safety Features (ESF) System Walkdown | |||
The NRC inspectors verified the operability of ESF systems by walking | |||
down selected accessible portions of the systems. The NRC inspectors | |||
verified valves and electrical circuit breakers were in the required | |||
position, power was available, and valves were locked where required. | |||
The NRC inspectors also inspected system components fcr damage or other | |||
conditions that could degrade system performance. , | |||
The ESF system walked down during this inspection period and the | |||
, | |||
documents utilized by the NRC inspectors during the walkdown are listed | |||

7. Onsite Followup'of Event | |||
The NRC' inspectors performed onsite followup of a reactor trip that | |||
' | |||
' occurred on July 24,'1986, due to a 10-10 steam generator water level | |||
condition. The NRC inspectors reviewed logs and computer printouts and | |||
discussed the~ trip.with cognizant personnel. The NRC inspectors | |||
verified the licensee had responded to the event in accordance with | |||
procedures and had notified the NRC as required in a timely fashion. | |||
The reactor trip occurred at approximately 13 percent power during a | |||
controlled reactor plant shutdown to Mode 3 to support maintenance on | |||
the main turbine generator. The 10-10 level in the steam generator was | |||
caused while the steam generator feedwater was being transferred from | |||
the main feedwater regulator valves to the bypasses. The licensee has | |||
experienced this same problem during previous plant startups and | |||
shutdowns and is evaluating methods to eliminate the problem. The | |||
subsequent startup on July 26, 1986, was accomplished with no | |||
significant problems. | |||
' | |||
No violations or deviations were identified. | |||
8. Monthly Surveillance Observation | |||

9. Quality Assurance (QA) Program Annual Review | |||
a. QA Program Implementation | |||
Duringapreviousinspection(IR 50-482/86-16) the NRC inspector | |||
had reviewed the WCGS onsite and offsite review committees. The | |||
licensee had a method for informing supervisory persunnel of new | |||
regulatory requirements by routing to them Inspection and | |||
Enforcement Bulletins (IEB), Generic Letters (GL), Information | |||
Notices (IN), and so forth. | |||
During this period, the NRC inspector examined the implementation | |||
of the QA audit program and their records program. | |||
b. Audit Program | |||
Through discussions with licensee personnel, review of the | |||
essential elements manual and review of sunmary documentation, an | |||
understanding of the audit program was obtained. | |||
. | |||
h | |||
- . | |||
' | |||
, | |||
-10- | |||
The basis of the audit program was the essential elements manual, | |||
i which summarizes into 39 topics (essential elements) the licensee's | |||
commitments and/or requirements reflected in 10 CFR Part 50, | |||
ANSI 18.7 (Quality Assurance for the Operational Phase of Nuclear | |||
Power Plants), WCGS TS, and the Final Safety Analysis | |||
Report (FSAR). The essential elements are subdivided into | |||
attributes which can be objectively evaluated. | |||
To audit a plant area, the auditor prepared the audit plan from the | |||
essential elements manual type of concern. Upon completion of the | |||
audit, if any discrepancies existed, methods existed that allowed | |||
execution of corrective actions as appropriate. Quality assurance | |||
audit frequencies, as required by TS, were on a biennial schedule. | |||
The audits were planned on an annual basis; however, if the | |||
essential element was voluminous, the audit may have been scheduled | |||
in segments over a two year period to assure that the minimum audit | |||
requirements would be met. In addition to the mandatory audits, | |||
lower tiered audits and surveillances were scheduled to support the | |||
main audit. | |||
The following audit packages were reviewed: | |||
Audit No. Title | |||

TE 50140-K066 Records Management | |||
TE 50140-K005 Quality Assurance Records | |||
The audits generally lasted four weeks. Auditors conducted | |||
entrance and exit summaries with the plant organization prior to | |||
start and at conclusion of the audit. The audit report clearly | |||
,~ | |||
defined the audit scope and results. Personnel conducting the | |||
audit were qualified as determined by NRC inspector review of | |||
training records. The audit questions and areas of interest | |||
reflected the requirements in the essential elements' manual. The | |||
audited organizations' response to audit findings were in writing, | |||
were timely, and adequately addressed the findings and | |||
recommendations. | |||

c. Records Program | |||
During this inspection, the NRC inspector reviewed Section 6.10 of | |||
the facility TS, ANSI N45.2.9-1974 (Requirements For Collection, | |||
Storage, and Maintenance Of Quality Assurance Records For Nuclear | |||
Power Plants), and the WCGS procedures listed below: | |||
o ADM 01-045, Revision 3, " Document Control Supervisor Duties | |||
and Responsibilities" | |||
o ADM 07-046, Revision 16, " Records, Administrative, and | |||
Storage" | |||
The WCGS records program was described in ADM 07-406. Maintenance | |||
and retention periods for records were described in the TS and | |||
various procedures. The Document Control (DC) Supervisor was | |||
assigned responsibility of maintaining the QA records and ensuring | |||
implementation of the record storage controls. Responsibilities | |||
had been assigned with controls established to ensure transfer and | |||
retention of construction phase records. The controls (ADM | |||
Procedure 07-406) established for record storage were in accordance | |||
with FSAR commitments; i.e., ANSI N45.2.9-1974. This procedure | |||
described the storage facility; designated the DC supervisor as | |||
custodian of the QA vault; described the filing / retrieval system | |||
utilized; established a method to verify that records were in | |||
agreement with the transmittal document; made provisions for | |||
governing access to files and maintaining accountability of records | |||
removed from storage; established methods for correcting | |||
information, filing supplemental information and disposing of | |||
superseded records with the required reviews and approvals | |||
specified. | |||
Individual section supervisors; i.e., instrumentation and control, | |||
maintenance, et cetera, were responsible for establishing retention | |||
periods of records not covered by the FSAR, TS, 10 CFR, and for | |||
authorizing the disposal of records no longer required. | |||
The NRC inspector verified through discussions with licensee | |||
personnel and a tour of the QA vault that: The environmental | |||
, conditions and fire suppression system were in accordance with | |||
commitments; records were listed on an index; records were readily | |||
retrievable from designated files and were not stored loosely but | |||
were firmly attached in folders; and records were stored in | |||
suitable file cabinets. | |||
No violations or deviations were identified. | |||

10. Design Changes and Modifications | |||
The NRC inspector reviewed design changes and modifications that the | |||
licensee had determined were not required to be approved by NRC and | |||
verified they were in conformance with TS and 10 CFR Part 50.'59. | |||
a. Design Changes | |||
The NRC inspector selected three design changes that were to be | |||
submitted with the annual report to the NRC that is required by | |||
10 CFR Part 50.59(b). For each of the design changes the NRC | |||
inspector verified: That the changes were reviewed and approved in | |||
a technically adequate manner in accordance with 10 CFR Part 50.59; | |||
that the design changes were reviewed and approved according to TS; | |||
and that established procedures were used. | |||
The three design change summaries follow: | |||
(1) Plant Modification Request (PMR) 01446, Revision 0, was | |||
originated to reinstall flow elements EM-FE924, 925, 926, | |||
and 927, which were originally installed backwards. | |||
(2) Safety Evaluations (SE) 86-SE-31 was originated to reverse | |||
the wires on Terminals TB4-8-01 and TB4-8-04 in Panel RP05BC | |||
for the emergency diesel generator "A" day tank level control | |||
circuit to make the wiring agree with the schematic. | |||
(3) SE 86-SE-44 was originated to demonstrate the operability of | |||
reactor coolant system pressure isolation valves BB PV8702A | |||
and EJ HV8701A by verifying that the measured leakage meets | |||
the requirements of TS 4.4.6.2.2. | |||
b. Temporary Modifications | |||
The NRC inspector reviewed the WCGS program for temporary | |||
modifications through review of Procedure ADM 02-101, Revision 15, | |||
" Temporary Modifications." The NRC inspector verified that | |||
temporary modifications were reviewed and approved according to | |||
Section 6 of the TS and 10 CFR Part 50.59. The procedure assigned | |||
each group supervisor responsibility for approving the temporary | |||
modification as correct, necessary, and required the use of | |||
detailed approved procedures. WCGS ADM Procedure 02-101 required: | |||
That a temporary modification log be maintained; that all | |||
outstanding temporary modifications were reviewed periodically; and | |||
i | |||
that temporary modifications be evaluated to determine the need for | |||
independent verification. | |||
No violations or deviations were identified. | |||

11. Core Thermal Power Evaluation | |||
The NRC inspector verified that the licensee's calculation of core | |||
.. | |||
thermal power was correct and that the procedure used was technically | |||
adequate. On July 18, 1986, at 0610 CDT, the NRC inspector performed a | |||
manual calorimetric using licensee Procedure STS SE-002, Revision 0, | |||
" Manual Calculation of Reactor Thermal Power." At that time computer | |||
point REV1118 was indicating 3407.3 MWth which corresponds to | |||
99.89 percent of licensed full power. The NRC inspector calculated a | |||
power level of 99.82 percent of full power. The NRC inspector then | |||
verified that all nuclear instrumentation channels were reading greater | |||
than 99.89 percent, but within acceptable margins. The NRC inspector | |||
reviewed STS SE-002 for technical adequacy, proper initial conditions, | |||
appropriate prerequisites and good engineering practice. The three | |||
typographical errors and one usage of incorrect units found were given | |||
to the Superintendent of Operations for correction. The correction | |||
factor of 0.4 percent for reactor coolant pump (RCP) heat added was | |||
found to be incorrect by 0.0254 percent, since this is within instrument | |||
error, this difference is not significant and the reactor engineer was | |||
notified of the difference. The proper correction factor for RCP pump | |||
heat is 0.3746 percent or 43.6 10E6 BTU /HR as identified in the | |||
preoperational test procedure results report for SU9-0025, Revision 0, | |||
" Reactor Coolant System Heat Loss." The NRC inspector on a random basis | |||
verified the correct number was used in Startup Test SU7-SC03.2, | |||
Revision 1, " Thermal Power and Statepoint Data Collection at 30 percent | |||
Power," and SU7-SC03.8, Revision 1, " Thermal Power and Statepoint Data | |||
Collection at 100 percent Power." The NRC inspector randomly reviewed | |||
TS Surveillance STS SE-001, Revision 5, " Power Range Adjustment to | |||
Calorimetric," performed on June 14-16, 1986, and verified that the | |||
power range nuclear instruments were properly adjusted to agree with the | |||
results of the heat balance and that data was reasonable, consistent | |||
with previous data and properly recorded. | |||
The NRC inspector by review of the STS master schedule verified that the | |||
frequency of calorimetrics was as prescribed by the licensee's TS. | |||
The NRC inspector by review of the appropriate surveillances verified | |||
that the plant instruments and computer points used for calorimetrics | |||
were calibrated in a traceable manor and that evaluation results were | |||
reviewed, approved, and documented in accordance with procedures. | |||
No violations or deviations were identified. | |||
12. Radwaste Processing | |||
During this inspection period, the NRC inspectors observed activities | |||
and reviewed procedures related to the processing of radwaste. A vendor | |||
was onsite processing primary and secondary evaporator bottoms | |||
concentrates. A licensee procedure was to provide valve lineups for | |||
supplying the radsaste to the vendors processing equipment. The vendor | |||
would then use his own procedures to process the radwaste. | |||
. _ _ | |||
* | |||
. . | |||
,, . | |||
-14- | |||
In discussions with cognizant licensee personnel, the NRC inspectors | |||
pointed out that the vendor's procedures and the licensee's procedures | |||
had not been integrated together in that they did not reference each | |||
other and that there was no definitive vehicle by which the vendor's | |||
procedures were implemented or controlled for use onsite. | |||
The licensee resolved this observation by establishing and implementing | |||
Procedure STS HC-227, Revision 0, " Vendor Processing of Primary Resins | |||
and Concentrates," which addressed interfaces with vendor procedures. | |||
No violations or deviations were identified. | |||
.13. Exit Meeting | |||
The NRC inspectors met with licensee personnel to discuss the scope and | |||
findings of this inspection on August 4, 1986. The NRC inspectors also | |||
attended entrance / exit meetings of other NRC region based inspectors | |||

On July 24,1986 the plant was shut down to Mode 3 to repair a stator
cooling water leak in the main generator. During the controlled
shutdown, the reactor tripped.at approximately 13 percent power due to a
1o-10 steam generator water level condition. The plant was returned to
Mode 1 on July 26, 1986.
3. Followup on Previously Identified NRC Items
(Closed) Violation (482/8526-02): Temporary changes not incorporated in
procedure as required.
The NRC inspector verified by review that the licensee's surveillance
procedure cover sheet has been revised to require that the test
performer verify that the latest revision of the surveillance test is
being used. This item is closed.
(Closed) Violation (482/8535-05): Failure to follow housekeeping
requirements.
The licensee took immediate action and cleaned up the areas which
created the housekeeping concerns identified in this violation. On
subsequent walkdowns, the NRC inspectors have observed that housekeeping
was being maintained as required. This violation is closed.
(Closed) Violation (482/8538-01): Failure to establish procedures for
certain activities that could affect the performance of safety-related
equipment.
The NRC inspector, by review of documents and plant walkdowns, verified
the following licensee actions related to this violation:
o Section 5.3.2 of Administrative Procedure ADM 01-034, Revision 8,
" Housekeeping and Cleanliness Control," has been revised to state
that hoist hooks shall be fully raised and ladders returned to
their designated storage location.
l
0 Permanent storage brackets for ladders have been installed at
seventeen locations in the plant and have been identified by signs.
i
o Storage of ladders was discussed at the safety committee meeting
held on April 2, 1986. Safety meetings were used to train
employees in the use of ladders.
During subsequent plant walkdowns, the NRC inspectors have not
identified any further instances where ladders and hoists could have
^
affected the operation of safety-related equipment. This violation is
closed.
f (Closed) Violation (482/8523-01): Failure to follow plant procedures.

The NRC inspector reviewed the letter which was issued to all
organizations which may be called upon to perfonn work in the plant and
verified that it was discussed with the appropriate personnel. In addition,
since this violation was first identified no other similar violations
have been discovered. This violation is closed.
(Closed) Violation (482/8530-01): Test port not reclosed in accordance
with procedure.
The NRC inspector reviewed five randomly selected procedures which
remove plugs in HVAC test ports and verified the procedures included
clear requirements to reinstall plugs in test ports. In addition, field
inspections by NRC inspectors have failed to identify any similar
violations to date. This violation is closed.
(Closed) Violation (482/8530-02): Inadequate procedure.
The NRC inspector reviewed STS IC-275A and STS IC-275B and verified that
the requirement for damper movement had been removed. In addition, the
sample results of the containment atmosphere drawn at 2100 CST on
July 26, 1985, was reviewed for abnormal results. This violation is
closed.
4. Review of Licensee Event Reports
During this inspection period, the NRC inspectors performed followup on
selected Wolf Creek LERs. The LERs were reviewed to ensure:
o The corrective action stated in the report has been properly
completed.
o Responses to the events were adequate.
o Responses to the events met license conditions, commitments, or
other applicable regulatory requirements.
o The information contained in the report satisfied applicable
reporting requirements.
o That any generic issues were identified,
o The report conformed to the guidelines contained in NUREG-1022 and
Supplements 1 and 2.
The following LERs were reviewed and closed.

The NRC inspectors had the following comments:
o ApplicableportionsofAdministrativeProcedure'ADM01-033,
~
'" Instructions Describing Reportability, Review, and Documentation
of Licensee Event Reports (LERs), and Defect Deficiencies,"
'
Revision 15, were reviewed for agreement with LER reporting
requirements,
r
o In general, the quality and adequacy of the licensee's LERs has
~
been improving. However, minor deficiencies were noted in the LER
information requirements. For example, five out of six LERs
,
reviewed did not discuss whether any previous similar events at the
i
plant were known to.the licensee. These deficiencies were
discussed with the licensee during this inspection period.
o During an inspection of control room area radiation monitor
instrunentation and chart recorders while following up on LER
482/86-019-00, the NRC inspector noted that Chart Recorder GT RR-58,
t " Unit Ventilation Effluent Release Rate," and GH RR-51, "Radwaste
Building Effluent Release Rate," were not scaled, but did have a tag
saying 0 to 100. None of the licensed operators questioned knew
what units the chart recorders used. Instrumentation and control
informed the NRC inspector that the chart recorders were calibrated
j from 10E1 to 10E13 micro Ci/sec. The licensee committed to install
i
the correct scales.
- '
l o -0n July 18,1986,'during a review of completed surveillances
related to LER 482/86-033-00, the NRC inspector observed that
,
STS CH-008A, " Emergency Diesel Fuel Storage Tank," performed on
June 1, 1986, was Revision 3 and that the data sheet for STS CH-0088,
, " Emergency Diesel Fuel Storage Tank," had been used. The plant safety
l review conmittee (PSRC) document control records showed that
<; *

.
-7-
STS CH-C08A, Revision 4 had been issued on May 14, 1986. The
records review indicated that the appropriate tank was sampled and
that the sample data met the TS criteria. This failure of the test
performer to use the correct procedure and revision, even though he
had signed off in Section 1 of the cover sheet that he had used the
correct procedure and revision, and failure of the surveillance
ost-performance review cycle to discover this error is a violation.
482/8617-01)
5. Operational Safety Verification
The NRC inspectnrs verified that the facility is being operated safely
and in conformance'with regulatory requirements by direct observation of
>
licensee facilities, tours of the facility, interviews and discussions
with licensee personnel, independent verification of safety system
status and limiting conditions for operations, and reviewing facility
records. The NRC inspectors, by observation and direct interview,
verified the physical security plan was being implemented in accordance
with the security plan and that radiation protection activities were
controlled.
By observing . valve position, electrical breaker position, and control
room indication, the NRC inspectors confirmed the operability of the
residual heat removal system and the emergency diesel generators.
The NRC inspectors also visually inspected safety components for
leakage, physical damage, and other impairments that could prevent them
from performing their designed function.
No violations or deviations were identified.
6. Engineered Safety Features (ESF) System Walkdown
The NRC inspectors verified the operability of ESF systems by walking
down selected accessible portions of the systems. The NRC inspectors
verified valves and electrical circuit breakers were in the required
position, power was available, and valves were locked where required.
The NRC inspectors also inspected system components fcr damage or other
conditions that could degrade system performance. ,
The ESF system walked down during this inspection period and the
,
documents utilized by the NRC inspectors during the walkdown are listed

7. Onsite Followup'of Event
The NRC' inspectors performed onsite followup of a reactor trip that
'
' occurred on July 24,'1986, due to a 10-10 steam generator water level
condition. The NRC inspectors reviewed logs and computer printouts and
discussed the~ trip.with cognizant personnel. The NRC inspectors
verified the licensee had responded to the event in accordance with
procedures and had notified the NRC as required in a timely fashion.
The reactor trip occurred at approximately 13 percent power during a
controlled reactor plant shutdown to Mode 3 to support maintenance on
the main turbine generator. The 10-10 level in the steam generator was
caused while the steam generator feedwater was being transferred from
the main feedwater regulator valves to the bypasses. The licensee has
experienced this same problem during previous plant startups and
shutdowns and is evaluating methods to eliminate the problem. The
subsequent startup on July 26, 1986, was accomplished with no
significant problems.
'
No violations or deviations were identified.

No violations or deviations were identified.
9. Quality Assurance (QA) Program Annual Review
a. QA Program Implementation
Duringapreviousinspection(IR 50-482/86-16) the NRC inspector
had reviewed the WCGS onsite and offsite review committees. The
licensee had a method for informing supervisory persunnel of new
regulatory requirements by routing to them Inspection and
Enforcement Bulletins (IEB), Generic Letters (GL), Information
Notices (IN), and so forth.
During this period, the NRC inspector examined the implementation
of the QA audit program and their records program.
b. Audit Program
Through discussions with licensee personnel, review of the
essential elements manual and review of sunmary documentation, an
understanding of the audit program was obtained.
.
h
- .
'
,
-10-
The basis of the audit program was the essential elements manual,
i which summarizes into 39 topics (essential elements) the licensee's
commitments and/or requirements reflected in 10 CFR Part 50,
ANSI 18.7 (Quality Assurance for the Operational Phase of Nuclear
Power Plants), WCGS TS, and the Final Safety Analysis
Report (FSAR). The essential elements are subdivided into
attributes which can be objectively evaluated.
To audit a plant area, the auditor prepared the audit plan from the
essential elements manual type of concern. Upon completion of the
audit, if any discrepancies existed, methods existed that allowed
execution of corrective actions as appropriate. Quality assurance
audit frequencies, as required by TS, were on a biennial schedule.
The audits were planned on an annual basis; however, if the
essential element was voluminous, the audit may have been scheduled
in segments over a two year period to assure that the minimum audit
requirements would be met. In addition to the mandatory audits,
lower tiered audits and surveillances were scheduled to support the
main audit.
The following audit packages were reviewed:
Audit No. Title
TE 50140-K116 Corrective Action dated 6/4/86
TE 50140-K096 Assignment Of Authority, Organization, and
Program Description
TE 50140-K086 Corrective Action dated 12/9/85
TE 50140-K066 Records Management
TE 50140-K005 Quality Assurance Records
The audits generally lasted four weeks. Auditors conducted
entrance and exit summaries with the plant organization prior to
start and at conclusion of the audit. The audit report clearly
,~
defined the audit scope and results. Personnel conducting the
audit were qualified as determined by NRC inspector review of
training records. The audit questions and areas of interest
reflected the requirements in the essential elements' manual. The
audited organizations' response to audit findings were in writing,
were timely, and adequately addressed the findings and
recommendations.

c. Records Program
During this inspection, the NRC inspector reviewed Section 6.10 of
the facility TS, ANSI N45.2.9-1974 (Requirements For Collection,
Storage, and Maintenance Of Quality Assurance Records For Nuclear
Power Plants), and the WCGS procedures listed below:
o ADM 01-045, Revision 3, " Document Control Supervisor Duties
and Responsibilities"
o ADM 07-046, Revision 16, " Records, Administrative, and
Storage"
The WCGS records program was described in ADM 07-406. Maintenance
and retention periods for records were described in the TS and
various procedures. The Document Control (DC) Supervisor was
assigned responsibility of maintaining the QA records and ensuring
implementation of the record storage controls. Responsibilities
had been assigned with controls established to ensure transfer and
retention of construction phase records. The controls (ADM
Procedure 07-406) established for record storage were in accordance
with FSAR commitments; i.e., ANSI N45.2.9-1974. This procedure
described the storage facility; designated the DC supervisor as
custodian of the QA vault; described the filing / retrieval system
utilized; established a method to verify that records were in
agreement with the transmittal document; made provisions for
governing access to files and maintaining accountability of records
removed from storage; established methods for correcting
information, filing supplemental information and disposing of
superseded records with the required reviews and approvals
specified.
Individual section supervisors; i.e., instrumentation and control,
maintenance, et cetera, were responsible for establishing retention
periods of records not covered by the FSAR, TS, 10 CFR, and for
authorizing the disposal of records no longer required.
The NRC inspector verified through discussions with licensee
personnel and a tour of the QA vault that: The environmental
, conditions and fire suppression system were in accordance with
commitments; records were listed on an index; records were readily
retrievable from designated files and were not stored loosely but
were firmly attached in folders; and records were stored in
suitable file cabinets.
No violations or deviations were identified.

10. Design Changes and Modifications
The NRC inspector reviewed design changes and modifications that the
licensee had determined were not required to be approved by NRC and
verified they were in conformance with TS and 10 CFR Part 50.'59.
a. Design Changes
The NRC inspector selected three design changes that were to be
submitted with the annual report to the NRC that is required by
10 CFR Part 50.59(b). For each of the design changes the NRC
inspector verified: That the changes were reviewed and approved in
a technically adequate manner in accordance with 10 CFR Part 50.59;
that the design changes were reviewed and approved according to TS;
and that established procedures were used.
The three design change summaries follow:
(1) Plant Modification Request (PMR) 01446, Revision 0, was
originated to reinstall flow elements EM-FE924, 925, 926,
and 927, which were originally installed backwards.
(2) Safety Evaluations (SE) 86-SE-31 was originated to reverse
the wires on Terminals TB4-8-01 and TB4-8-04 in Panel RP05BC
for the emergency diesel generator "A" day tank level control
circuit to make the wiring agree with the schematic.
(3) SE 86-SE-44 was originated to demonstrate the operability of
reactor coolant system pressure isolation valves BB PV8702A
and EJ HV8701A by verifying that the measured leakage meets
the requirements of TS 4.4.6.2.2.
The NRC inspector reviewed the WCGS program for temporary
modifications through review of Procedure ADM 02-101, Revision 15,
" Temporary Modifications." The NRC inspector verified that
temporary modifications were reviewed and approved according to
Section 6 of the TS and 10 CFR Part 50.59. The procedure assigned
each group supervisor responsibility for approving the temporary
modification as correct, necessary, and required the use of
detailed approved procedures. WCGS ADM Procedure 02-101 required:
That a temporary modification log be maintained; that all
outstanding temporary modifications were reviewed periodically; and
i
that temporary modifications be evaluated to determine the need for
independent verification.
No violations or deviations were identified.

11. Core Thermal Power Evaluation
The NRC inspector verified that the licensee's calculation of core
..
thermal power was correct and that the procedure used was technically
adequate. On July 18, 1986, at 0610 CDT, the NRC inspector performed a
manual calorimetric using licensee Procedure STS SE-002, Revision 0,
" Manual Calculation of Reactor Thermal Power." At that time computer
point REV1118 was indicating 3407.3 MWth which corresponds to
99.89 percent of licensed full power. The NRC inspector calculated a
power level of 99.82 percent of full power. The NRC inspector then
verified that all nuclear instrumentation channels were reading greater
than 99.89 percent, but within acceptable margins. The NRC inspector
reviewed STS SE-002 for technical adequacy, proper initial conditions,
appropriate prerequisites and good engineering practice. The three
typographical errors and one usage of incorrect units found were given
to the Superintendent of Operations for correction. The correction
factor of 0.4 percent for reactor coolant pump (RCP) heat added was
found to be incorrect by 0.0254 percent, since this is within instrument
error, this difference is not significant and the reactor engineer was
notified of the difference. The proper correction factor for RCP pump
heat is 0.3746 percent or 43.6 10E6 BTU /HR as identified in the
preoperational test procedure results report for SU9-0025, Revision 0,
" Reactor Coolant System Heat Loss." The NRC inspector on a random basis
verified the correct number was used in Startup Test SU7-SC03.2,
Revision 1, " Thermal Power and Statepoint Data Collection at 30 percent
Power," and SU7-SC03.8, Revision 1, " Thermal Power and Statepoint Data
Collection at 100 percent Power." The NRC inspector randomly reviewed
TS Surveillance STS SE-001, Revision 5, " Power Range Adjustment to
Calorimetric," performed on June 14-16, 1986, and verified that the
power range nuclear instruments were properly adjusted to agree with the
results of the heat balance and that data was reasonable, consistent
with previous data and properly recorded.
The NRC inspector by review of the STS master schedule verified that the
frequency of calorimetrics was as prescribed by the licensee's TS.
The NRC inspector by review of the appropriate surveillances verified
that the plant instruments and computer points used for calorimetrics
were calibrated in a traceable manor and that evaluation results were
reviewed, approved, and documented in accordance with procedures.
No violations or deviations were identified.
12. Radwaste Processing
During this inspection period, the NRC inspectors observed activities
and reviewed procedures related to the processing of radwaste. A vendor
was onsite processing primary and secondary evaporator bottoms
concentrates. A licensee procedure was to provide valve lineups for
supplying the radsaste to the vendors processing equipment. The vendor
would then use his own procedures to process the radwaste.

In discussions with cognizant licensee personnel, the NRC inspectors
pointed out that the vendor's procedures and the licensee's procedures
had not been integrated together in that they did not reference each
other and that there was no definitive vehicle by which the vendor's
procedures were implemented or controlled for use onsite.
The licensee resolved this observation by establishing and implementing
Procedure STS HC-227, Revision 0, " Vendor Processing of Primary Resins
and Concentrates," which addressed interfaces with vendor procedures.
No violations or deviations were identified.
.13. Exit Meeting
The NRC inspectors met with licensee personnel to discuss the scope and
findings of this inspection on August 4, 1986. The NRC inspectors also
attended entrance / exit meetings of other NRC region based inspectors
