Operational Safety Verification - (71707)(93702)
The plant began this inspection period in Power Operation (Mode 1) near 100% reactor power. On September 15, the unit began a power coastdown by maintaining a constant boron concentration and reducing power to ma!ntain criticality.
4.
a.
Control Room Activities Control Room tours and observations were performed to verify that f acility operations were being safely conducted within regulatory requirements.
These inspections consisted of one or more of the following attributes as approp"iate at the time of the inspection.
- Proper Control Room staffing
- Control Room access and operator behavior
- Adherence to approved procedures for activities in progress
- Adherence to TS LCOs
- Observance of instruments and recorder traces of safety related and important to safety systems for abnormalities
- Review of annunciators alarmed and action in progress to correct
- Control Board walkdowns
- Safety parameter display and the plant safety monitoring system operability status
- Discussions and interviews with the OS0Ss, SSs, R0s, and the STAS (when stationed) to determine the plant status, plans, and to assess operator knowledge Review of the operator logs, unit log and shift turnover sheets On September 23, during a control room tour the inspector questioned the illuminated status of the SSMP "B" train charging system.
The inspector was informed that the associated Boric Acid Pump Motor handswitch had been placed in the Stop position to preclude an automatic start. A recent engineering evaluation had concluded that since those pumps had a common miniflow line that possible pump damage would result if nn discharge path was provided. To preclude damago, engineering reviewed FSAR section 9.3.4.1.2.5.2 and noted that the description states that one pump is normally aligned to supply boric acid to the suction header of the charging pumps while the second serves as a standby and that manual or automatic initiation of the reactor coolant makeup system will start one pump. Engineering review of the elementary wiring diagram (1X30-BD-C01F) concluded that to preclude both pumps from starting simultaneously that one handswitch would have to be in the stop position. This same diagram depicts that the stop position would illuminate the SSMP. Procedure 13701-1 was subsequer.tly revised to implement this operation. Operation personnel subsequently submitted a request for engineering review (N0 88-0565)
to resolve the illumination problem.
The inspector determined that no compensatory action was established for the SSMP. FSAR Section 7.5.5
,
!
discusses SSMP design and operation.
This section states that the
-
-
-
'
..
.
..
I requirements of RG 1.47 are met for system level indication of a bypassed or inoperable system. When a monitored component is not in a required position, the corresponding light illuminates. Manual illumination capability is also provided to allow the operators under administrative control to illuminate the panel when unmonitored components render the system inoperable. The inspector addressed the concern to both operations and engineer'ng management that this operating procedure removes the ability of the SSMP to monitor one train of CVCS and this issue thould be resolved to restore SSMP monitoring capability. In the interim, operations personnel are placing the handswitch to the auto position and are verifying that the SSMP light extinguishes. Resolution of this item is considered an IFI and is identified as:
IFI 50-424/88-43-01 "Verify resolution of restoring the SSMP to a condition to correctly indicate the operability status" No violations or deviations were identified.
b.
Facility Activities Facility tour.s and observations were performed to assess the effectivener.s of the administrative controls established by direct observation of plant activities, interviews and discussions with licensee personnel, independent verification of safety systems status and LCOs, licensee meetings and facility records.
During these inspections the following objectives are achieved:
(1) Safety System Status (71710) - Confirmation of systen operability was obtained by verification that flowpath valve aligrmtnt, control and power supply alignments, component conditions, and support astems for the accessible portions of the ESF trains were prcpe".
Tne 'enaccessible portions are corfirmed as availability permits.
Additional indepth inspecdon of the i
containment cooling system was performed to review the system lineup procedure with tha plant drawings and u * built configurations, and compare va7ve/daper remote and locat indications.
The inspector reviewed the noient operating
,
umperature profile to verify that temperature measurements inside containment are representative of actual conditions. This
.
activity was performed to complete NRC temporary instruction 2515/98.
The inspectv concluded that the temperatures inside containment are routinely maintained below the environmental qualification limit of 120 F.
Storage of material and (2) Plant Housekeeping Conditions
-
components and cleanliness conditions of various aress throughout tne facility were ot, served to determine whether safety and/or fire id:st existe.

'
Which Was Incorrectly Installed During MWO 18805643.
While obse ving MWO 18805645, the inspector noted that the
'
licensee had cut the wrong weld. Weld Number W106 was cut in lieu of W103 as directed by the MWO. The root cause was due to the fact that the welder failed to review the MWO on station prior to umment.ing the cutting operation. A deficiency card was written upon discovary by the welcing foreman and the MWO was
-
,
subsee,uently rsedif f ed to ratisfactorily complete the work. The
-
procedure violatior, did not result in a TS LCO violation, however it was representative of a failure to in,pl emort a procedura
'
required by TS 6.7.1.
This item represents a viointion of NRC requirement which meet the criteria for non citation.
LIV 50-424/88-40-01, "Failure to Implement KWO 18805645 frocedure Required by TS 6.7.1" During the morning OSOS briefing on September 26, the inspector learned that MWO 18806684 was planned for accomplishment to correct the installation of flow element 1-FE-929. As a result of inservice testing being conducted to obtain new baseline data following MWO 18805643, engineering determined that the flow

,
element was installed backwards. A DC was written to document the deficiency. The inspector requc'ted a further description of how the situation had occurred in light of the NRC. violation 50-425/88-12-01. This violation should have alerted the licensee, and appropriate controls should have been established on Unit 1 to preclude improper installation. On September 29, the inspector-was informed that maintenance would be performing a root cause determination. Pending completion of the licensee's review this item is considered to be an IFI and is tracked 50-424/88-43-02 IFI "Review Licensee Corrective Action For Correct Installation Of Flow Elements."

(1) DC reviews:
DC 1-88-2513 "Containment Ventilation Isolation Actuation." On September 7 at 1:57 p.m.,
with the unit at 100% power an inadvertent shorting of a vital 120 VAC power supply resulted in an ESF actuation.
personnel were in the process of removing a temporary modification to restore the fuel handling building
monitors to service. The power transient which occurred resulted in Monitor 1RE-003 being affected. Monitor 1RE-003 provides the actuation of the Containment Ventilation Isolation.
All components required to respond actuated properly.
This item will receive further review when submitted as a LER pursuant to 10 CFR l-50.73(a)(2)(iv).
DC 1-88-2574 "Loss Of Offsite ENS Communications." On
-
September 15, the NRC resident requested the SS verify ENS operability. The Shift Supervisor responded and made a proper notification to the NRC operations center and provided instructions to the Duty Officer on how to call the control room.
r DC 1-88-2649 "DG 1B Trip On High Lube Oil Temperature." On September 23, 1B tripped on high lube oil temperature. Lube oil temperature at the time of the trip indicated 169 F.
The trip
setpoint of 200 F was not exceeded.
This item was discovered during the performance of surveillance 14980-1.
During retest, no unusual / abnormal indications were noted.
Lube oil temperatures were taken at 10 minute intervals using installed temperature gages and contact pyrometers. This item will receive further followup when submitted as a 30 day special report per TS 4.8.1.1.3.
OC 1-88-2680 "Security Violation Due To No Compensatory Post Being Established When The AFW Missile Shield Was Removed
.
(Between The AFW Building And Control Building) For AFW System Mainternance." On September 26, the lictisee discovered that. the
.
AP4 Missile shields had been removed to perform maintenance on act l
l apparent steam leak. The removal oc urred on Septemour 12 when
!
operations personnel thought a steam leak existed in the trench.
Upon removal of insulation, it was determined that rain water was
'
the source of staam.
The insulation was being replaced when a
'
plant engineer questioned the lack of security.
Shortly thereafter, engineering determined that the missile shields need replacement. Maintenarce replaced the shields within the six hour requirement of TS 3.7.1.2 action a.
Further engineering review concluded that removal of these missile shields can be
!
allowed provided reinsta11ation measures are taken during a Tornado Watch.
The NRC inspector expressed concern over the
licensee's program for ensuring that the plant hazard features
'
are properly maintained or compensated for during maintenance. A i

This item is identified as: 50-424/88-43-03 IFI "Review Licensees Program For Enduring Hazard Protection Is Assured."
(2) The following LERs -were reviewed and are ready for' closure pending verification that the licensee's stated corrective actions have been completed.
(a) 50-424/88-23, Revision 0
"Inadequate Design Leads To
.
Condition Prohibited By Technical Specification." On July that several
LER 88-020-00 was issued, identifying electrical penetrations may not have been ' provided with
~
adequate redundant overload protection. As a result of the interpretation for reportability of the event, two previously identified ~ deficiencies have been reevaluated for reportability. As a result of the re9 valuation, an event that was discovered on August 14, 1987 was determined to be reportable on July 28, 1987. The other event was discovered on July 7,1987 and determined to be reportable on August 11, 1987. It was determined that for each event, redundant overload protection may not have been adequate for the
,
'
entire range of protection as required by RG 1.63.
TS 3.8.4.1 requires i: hat electrical penetration overload orttection may not have been provided for several penetrations, and Unit 1 may have been operating in a condition prohibited by TS until the event-was discovered.
For each event the Limiting Condition for Operation action statement TS 3.8.4.1 was implemented on the event discovery dates of July 7,19fJ and August 14, 1987.
The event on August 14, 1987 involved electrical penetrations No. 12 and No. 69, concerning the #12 and #14 AWG conductors.
The other event on July 7,1987 involved penetrations No. 03,
!
14, 34, 41, 60, and 61, concerning #10 AVG conductors. The I
inadequate overload protection was discovered during a broadness review for Unit 2 by the designer, Bechtel Power Corporation.
The cornetive action has been completed for
the event of August 14, 1987.
The correettvo action for the
'
event of July 7,1987, requirer, an outage and hr.s been scheduled during the upcoming refueling ostage.
This action
is scheduled to be completed by November 15, 1988.
This
,
item will remain open pending completion of the corrective
-
work.
(3) The following LERs were reviewed and closed.

Cooling System Valve Controller Failure." On April 7, the
<
unit tripped from 100% power when stator cooling water temperature control valve, TCV-6800, failed in the heat
exchanger bypass position.
In this-condition temperature became elevated and actuated a turbine trip. This event was
,
reviewed during NRC Report 50-424/88-20. Maintenance to correct the failure was reviewed. This LER identified that AFW valve 1HV-5139A breaker tripped open as operators
!
attempted to throttle flow to SG #1. This failure appears to be identical to the failure discussed in LER 87-20. The LER does not specifically state that the handswitch was replaced nor does it link this LER with the previous LER.
The work order which repaired the AFV switch was reviewed to verify proper work completion.
LER 50-424/87-20 is also closed. The inspector has no further questions.
(b) 50-424/88-09, Revision 0
"Inadequate Health / Physics Controls Allows Shipm'ent Of Check Source." On April 6, the licensee was informed by Westinghouse that an In-vent radiation monitor had been shipped to their Baltimore, MD facility with a radioactive source installed without the appropriate shipping papers and labels. As indicated in NRC Report 50-424/88-17, this item was referred to the Regional Radiation Specialists for followup during the next routine inspection.
This item is closed based on the review conducted by regional inspection, NRC Report 50-424/88-28.
(c) 50-424/88-11, Revision 0 "Inadequate Con. trol Of Effluent Monitor Alarm Setpoint Leads To Technical Specification Violation." On April 11, the alert alarm and high alarm setpoints for the turbine building drain effluent monitor illE-0848 were found to be set too high. This condition existed since March 9 when the monitor was restored to operable status. TS 3.3.3.9 requires that this instrument be cpecabic with alarm setpoints determined with the methodology and parameters in the OMsite Oose Calculation Hanual. Instead of using the correct setpoint, a temporar.v setpoint was vertiled during the return to service on March 9.
This item was reviewed in NRC Report 50-424/88-20 for
,
enforcement.
The inspector reviewed the summary of
'
cor ective action dated April 21, 1988.
Changes to Procedure 34226-C were reviewed.
The inspector has no further questions.
(d)*50-424/88-13, Revision 0 "Manual Reactor Trip Due To Failure Of MFIV" On April 24, 1983, at 0922 COT, a manually initiated reactor trip occurred with the reactor plant at approximately 100% of rated thermal power. The Loop 4 MFIV
,
had failed closed and would not respond to an open signal.
[

'
,
.
,.
The manual trip was initiated in anticipation of receiving a SG low level setpoint automatic reactor trip. The direct cause of the event was No. 4 MFIV failed closed. The root cause was that an intermittent failure of an air solenoid valve coil led to the closure of No. 4 MFIV. Corrective actions included replacing each component, which reasonably could have caused the valve to fail closed. The components consisted of two electrically operated air solenoids, four electrical relays and two timer relays (agastats).
The components were replaced prior to the restart of the unit.
The removed parts were energized in the maintenance shop in a configuration which simulated the installation in the plant. All parts initially functioned as designed. After one intermittent failure, one of the air solenoids failed permanently. The third action in the report indicated that an engineering evaluation of the control circuit was in progress. The design change, DCR 89-023, was reviewed with the responsible engineering supervisor. While the design is to be implemented in a future outage, the inspector determined that this is a plant enhancement item and not necessarily corrective action for the event described in the LER. The inspector has no further questions regarding this issue.
(e) *SG-424/88-14, Revision 0 "Missed Surveillance Due To Personnel Error And Inadequate Communications." On April 25, the licensee discovered that a Technical Specification surveillance test had not been performed within the required time interval.
In accordance with TS 4.0.5, the surveillance for the containment air radioactivity monitor inlet valves, HV-12975 and HV-12976, and outlet valves, HV-12977 and HV-12978 was required to be performed no later than April 25, 1988, at 0902 COT. As soon as the US$ was informed it had been missed, the surveillance was performed immediately and satisfactory.
On May 13, at approximately 1400 CDT, it was identified that the plant should have entered TS 3.0.3 on April 25, since both isolation valves for the two penetrations were inopera' ole and a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> report was made to the NRC.
This event occurred because the USS failed to utilize the scheduling document. Also, the 0503 was aware of the surveillance and when it was due, but failed to inform the USS.
The TS 3.0.3 entry was not performed because the USS and the OSOS failed to perform an adequate technical review of the system condition.
Corrective actions includes instructing appropriate personnel on the use of the surveillance scheduling documents.
These documents will be used during shift relief to improve communication and awareness.
This item was previously reviewed ir. NRC Report 50-424/88-25 for

enforcement.
This inspection reviewed the documents utilized to instruct operators dated June 10, 1988.
The inspector has no further que.tions.
(f) 50-424/88-15, Rev 0 "Missed Surveillance Due To Personnel Error." On May 24, the licensee discovered that the monthly Analog Channel Operational Test surveillance for the Containment Radiation Level monitors, 1RE-0005 and 1RE-0006, had not been performed since August 1987. An investigation rev'ealed this TS surveillance (4.3.3.1) was linked to another TS surveillance (4.3.2.1) with the same requirement.
Due to a TS change in August 1987, the TS 4.3.2.1 surveillance was deleted without realizing that TS 4.3.3.1 surveillance was no longer to be addressed. This event was caused by personnel error when an inadequate review of the TS changes was performed to determine the necessary changes to the surveillance data base.
The procedure did not provide for data base revisions.
Corrective actions include review of previous TS revisions to determine if other surveillance data base changes were needed.
The procedure has been revised to require a two party review for data base changes and will not allow "linking" between the TS surveillance items. The surveillance for monitor 1RE-0005 was performed satisfactorily on May 24, but on May 25, monitor 1RE-0006 failed the surveillance.
Since only one operable monitor is required, the action statement was no longer applicable. This item was reviewed for enforcement in NRC Report 50-424/88-25.
The change to Procedure 80012-C was verified to have the revision and the data change was reviewed.
(g) 50-424/88-17, Revision
"Inadequate Procedure And Procedure Violation Leads To Missed Surveillance." On June 5, 1988 at approximately 1520 COT it was discovered that a liquid release was being performed prior to completing a source check of the radiation monitor 1RE-0018. The source check is a Technical Specification requirement prior to a release.
The radwaste operator was notified and the release was stopped at approximately 1525 COT.
This event was caused by an inadequate procedure.
The procedure which administratively contrcls the relvase of liquid radioactive waste did not requ'.re the source check to be performed.
Two separate procedure violations, one by a chemistry technician and another by a radwaste operator, also contributed to toe event.
Corrective actions include a revision to the procedure to require a source check to be performed and counseling of the involved personnel on the importance of following the procedures.
This item was reviewed for enforcement in NRC Report 50-424/88-31.
The inspector

(h) 50-424/88-18, Revision 0 "Inadequate Work Instructions Lead f
To Techr.ical Specification ' Violation." On June 6, 1988 at t
0959 COT, it was determined that Unit I had been operated in a condition prohibited by the TS. On June 5, 1988 at approximately 1530 COT, work was performed on a particulate radiation monitor 1RE-2562A. Due to the system' alignment, when the coverplate was removed from 1RE-2562A, the sample flow to monitor 1RE-2562C was such it was also rendered inoperable. On June 6,1988 at approximately 0028 CDT, the Containment Normal Sump Level was declared inoperable. At
!
0954 COT on June 6, 1988, it was determined that 1RE-2562C i
should have been declared inoperable when the coverplate for
'
the A channel was removed and a six hour Hot Standby action i
statement should have been initiated, when the Containment
Normal Sump Level was inoperable.

because of inadequate work instructions tu the maintenance
,
crew.
Work planning will contact chemistry for input to TS
related work orders for the Plant Effluent Radiation Monitor System, prior to being issued to the field. Maintenance will receive training and will contact the chemistry foreman
,
prior to removing any monitor from service. This item was reviewed for enforcement in NRC Report 50'424/88-31.

"Rear. tor Trip Oue To Lightning l
Strike." On July 31, lightning struck the Containment
-
I building and a reactor trip occurred.
An investigation revealed that the electrical surge from the lightning strike I
shutdown the output of the CROM power supplies allowirg the
!
rods to drop into the core, as designed.
Several other plant systems were affected by the lightning strike, but these had no major impact on plant operations.
The
-
electriedi surge from the lightning strike had clased the
,
CROM positive 24 volt DC and negative 24 volt DC power
!
supplies to automatically shut down. All power supp1'es in
!
,
!
the CROM power supply cabinets were reset.
Loss of these l
power supplies had caused power interruption to the CRN4 l
thyristors, allowing the rods to drop into the core. This
-
item was reviewed in NRC Report 50-424/88-31 listed a<.
DC 1-88-2125.
The inspector has no further questions.

Plant Review Board - (40700)
This inspection consisted of a review of the licensee's Onsite Review t
committee to determine if any significant safety-related responsibilities
.f of the PRB are not adequately being met. The following requirements, guidance and licensee commitments were utilized as appropriate:
-
ANSI N18.7-1976-i
-
RG 1.33 Revision 2, 1978
-
.
FSAR section 13.4.1
-
-
Technical Specification l
-
{
This review included ;ttendance at two PRB meetings and review of selected i
meeting minutes.
The licensee's administratfve procedure 00002-C "Plant
[
Duties and Responsibilities" was reviewed against
'
Review Board
-
appropriate commitments. The review was performed to determine if the PRB l
is properly fulfilling its function in the folleding areas:.
Compliance with the composition, duties and responsibilities as
-
described in the TS,
Review of all reportable events,
-
Investigation of all violations of TS including recommendations to
-
prevent future recurrences, Review of plant operations to detect potential nuclear safety hazards,
-
'
and, Review of proposals which could affect nuclear safety,
-
Amendment number 37 to the FSAR apparently was sent to and issued by the i
NRC with neither the PRB nor General Manager's review. A DC (#1-88-2577)
l has subsequently been written. Future corrective action is dependent upon
[
the disposition of the DC. Procedure 00402 Rev 8, License Document Change f
Request, paragraph 3.2.1 specifies that the PRB shall review License i
Documents as specified by the General Manager. This item represer.ts a i
