                                  PSE&G personnel displayed excellent overall performance in the development, pre bricling,

                                  Operators exhibited poor performance during the conduct of an infrequently performed                                                                            l

                                  and conservative decision making with regard to reactivity management was not

                                  by control room observers. (Section 04.1)
,
                                  The inspectors judged that Quality Assurance findings were well supported, independent,
-
                                  and promptly referred to station management for action. Quality Assurance oversight of
                                  control room activities was usua'ly good. (Section 07)

                                  - Maintenance department technicians exhibited adequate performance during the conduct of
                                  outage work activities and testing. While procedure and work order usage was generally
                                  good, deficiencies in interdepartmental coordination and foreign material exclusion controls
                                  were evident. (Section M1.1)
                                  Numerous unplanned emergency diesel generator start attempts and equipment restoration
                                  delays were encountered as a result of poor work centrols over mechanical govemor
                                  maintenance and replacements. (Section M4.1)
                                  Maintenance technicians improperly set up the mechanical overspeed trip device for the                                                                          4
.                                  reactor core isolation cooling turbine in part due to weak procedural guidance, which
                                  complicated a subsequent tutbine overspeed event. Insufficient verting of the turbine
                                  control oil system, again partly because of limited proceduro guidance, was judged to be
                                  the primary cause of the overspeed event. (Section M4.2)

                                    PSE&G performed a detailed and thorough evaluation of the f ailed core spray nozzle weld
j                                    history, previous nondestructive testing, and through wallleak causal f actors. Proposed-
                                    corrective actions were judged to be reasonable and appropriately focused on preventing
                                    recurrence. However, the f ailure to detect and repair a weld flaw in 1995 during a focused                                          i

                                    inadequate surveulance test procedure development led to the undetected inoperability of
,
                                    one train of the filtration, recirculation, and ventilation system. Corrective actions were                                          ;

                                    PSE&G promptly developed and implemented an acceptable design cho. ige packege to                                                    !

                                    Engineering department prepared safety evaluations were of good quality and were
                                    appropriately focused on the potential nuclear safety impact of the plrnt design or
                                    equipment changes. (Section U2.1)
                                    PSE&G acted promptly and effectively in the resolution of a self identified issue involving a
                                    potential secondary containment bypass leakage pathway. (Section E8.4)

                                    PSE&G maintained an effective site security program. Management support of program

                                    objectives was evident. Performance of security department person.nc! cnd equipment
                                    were generally good.
,
                                    PSE&G's provisions for land vehicle control measures satisfied regulatory requirements and
                                    licensee commitments. The site protected area barrier was properly installed and
                                    maintained, and satisfied the requirements of the NRC approved security plan.

.
      QM General Observatlora
        a. jnsocution Scone 171707)
          Throughout the report period, the inspectors routinely reviewed and obserwd
          operator performance with respect to technical specification (TS) action statement
          tracking, proceduto compliance, attention to detail, and reportable event accuracy
          and timeliness. Quality assurance (OA) efforts were also assessed.
        b. Qb.tmiyations and Findinas
          The inspectors witnessed inconsistent performance by operators during their
          conduct of routine and off normal activities. For example, reactor fuel reload
          activities were executed very well, in contrast to the offload activities earlier in the
          outage. All fuel moves were performec'in a single dimension, and no errors were
          noted in bundle selection or placement. As noted in section 01.2 below, efforts
          involving the reactor cavity drain down were conducted effectively. Shutdown
          cooling and spent fuel pool decay heat removal system flow paths were closely
          controlled and protected. Control room operators were generally f amiliar with most
          work being conducted in the plant.
          OA inspector coverage in the control room was frequent and provided generally
          good independent assessment of plant activities. Of particular note, a OA inspector
          questioned operators on whether a decision to commence core alterations
          (operational condition') from operational condition 5 was consistent with TS 3.0.4
          since two trains of the filtration, Iacirculation and ventilation system (FRVS) were
          inoperable. TS 3.0.4 mandates that entry into an operational condition shall not be
          made when conditions for the limiting conditions for operation (LCO) are not met
          and the associated action statement ultimately requires a plant shutdown. The
          FRVS TS 3.6.5.3 LCO requires that all six FRVS recirculation units be operable in
          operatii, ial condition'. Because of OA intervention in this issue, a potential TS
          violation was avoided during the operational condition change.
          The inspectors noted other performance deficiencies during the report period.
          Specifically, on November 7,1997, relieving operating shitt personnel questioned
          off going operators about the status of the safety parameter display system. At
          that point off going operatorr reallred that the system had been inoperable for
          nearly 12 hours, since the degraded condition was first identified and
          communicatsd to engineering personnel for resolution earlier in their shif t. Operators
          appropriately recognized that this condition required a non-emergency 10 CFR
            50.72 report to the NRC as a " major loss of emergency assessment capability" in
          accordance with the Hopa Creek emergency classification guide. Operations
          management concluded that this reportable event resulted from inadequate
          turnovers, follow up, and communichtions.

                  Othat weaknesses were identified as well. A loss of offsite power / loss of coolant
                  accident (LOP /LOCA) surveillance of the *B" 4100 VAC vital bus had to be rapeated            >
                  when the *B" residual heat removal system pump failed to start because the motor
                  supply breaker switch was inadvertently lef t in " pull to lock." Implementation of
                  several test procedures, including a reactor core isolation cooling system valve
                  inservice test procedure observed by the inspectors, did not meet department
                  expectetions for placekeeping. A reactor auxiliaries cooiing system head tank
                  overflowed while troubleshooting continued on an emergency diesel generator                    ;
                  control system because operators did not maintain full cognizance of system status.
                  Though not anticipated, a service water pump automatically started as designed                i
                  during a remote shutdown panel test because the pump controls were left in
                  automatic during the activity. While performing core alterations, secondary
                  containment pressure went positive with respect to atmospheric conditions during
                  recovery from a LOP /LOCA surveillance when a reactor building ventilaCon
                  subsystem tripped. The unreliability of this subsystem had been demonstrated by
                  earlier unexplained trips, and caused the inspectors to question the decialen (af ter
                  the f act) to continue fuel movements during the noted LOP /LOCA tert.
    c.            C,onclusiont
                  Operators demenstrated inconsistent performance overall, and exhibited notable
                  weaknesses with respect to attention to detail and awareness of equipment status..
                  Quality assurance oversight of control rooms activities was usually good.
  QL2 Reactor Cavity and Vessel Drain Down Evolution
    a.            Impection Scope (71707)
                  The inspectors observed portions of the planning, briefing, and implementation of a
                  first time evolution involving a reactor cavity and vessel drain down to suoport weld
                  repair efforts on the "A" core spray line nozzle.
                                                                                                                ;
    b.            Observations and Findinos
                  Weld repairs for the through wallleakage on the "A" core spray nozzle (see NRC
                  Inspaction Report 50 354/97 07 for details) required that the vessel penetration be
                  drained of water. Because this penetration is not isolable from the reactor vessel,
                  operators devised a plan for draining the cavity and vessel to a level below the
                  nozzle to support the work. The reactor fuel bundles were completely offloaded
                  into the spent fuel storage pool. The inspectors reviewed the newly prepared
                  procedure, which was in part based on other industry experience, and jedged it to
                  be of good depth and quality. PSE&G completed thorough reviews of the
                  procedure, which included a final approval by the station operations review
                  committee.
                  The pre evolution briefing was timely and comprehensive, and was attended by a
                  wide array of direct and peripheral evolution participants. Contingency measures
                  were thoroughly discussed, and effective communications were stressed.

      Because the entire core had been transferred to the spent fuel storage pool,
      operators planned a functional test of the residual heat removal fuel pool cooling
      assist mode bnfore the fuel pool getes were installed. The inspectors observed the
      functional terit, an activity which had not been perforrned since Hope Creek pre-
      operational testing. Based in part on a prior detailed procedure walk through, the      ;
      test was completed without error or incident.
      Operators properly conducted the drain down evolution using the newly developed
      procedure. Appropriate actions were taken upon discovery that the equipment pool
      gate seals were leaking water at a rate of several hundred gallons per minute,          ,
      Oulck recognition and timely response !n accordance with pre planned contingencies
      and briefings ensured that no additional complications were encountered. The gate
      seals were repairet, and the drain down was completed successfully. The
      inspectors witnessed excellent management oversight and interdepartmental                l
      coordination during this activity.                                                      +

  QL1 Shutdown Maroin flamonstration
  a.  ADippetion Scone U1707)
      The inspectors observed portions of a post refueling reactor shutdown margin
      demonstration performed to demonstrate compliance with technical specification
      3.1.1.
  b.  Observations and Findinas
      On November 12,1997, with the plant in operational condition 5 (reactor vessel
      head removed). control roon, operators began a core shutdown margin
      demonstration in accordance with procedure HC.RE ST.ZZ 0007(O). This test                ;
                                                                                                '
      involved the full withdrawal of twenty control rods (of 185 total) selected by the
      reactor engitioering .tarf. Operamrs invoked "special test exception" TS 3.10.3 to
      permit conduct of this infrequently p9rformed svolution since the test required the
      mode switch to be placed in the **.tartup" pc ition, defeating the one-rod out
      interlock normally required le operational condition 5. The inspectors verified that all
      associated TS required conditions were satisfied during performance of the test,
      which included reactor protection system (RPS) shorting link removal and the need        '
      fo % dependent oversight and verification of test procedure compliance by a
      " technically qualified member of the staff," in this case the reactor engineering
      department supervisor, since the rod worth minimiter was inoperable.

      Operators experienced difhculty withdrawing several of the test-designated control
      rods. As cuch, early in the evolution during an initial observation, the inspectors                  ,
      noted that operators appropriately implemented step 4.6 of the stuck control rod                    l
      procedure, HC.OP AB.ZZ 104(O), which requires that control rod drive (CRD)
      hydraulic system drive water pressure be " raised in 50 psiincrements" until the
      tod(s) were freed during single notch attempts, at which time the pressure "should
      be immediately restored to the norrnal range" (260 270 psi). However, later in the
      evolution during a subsequent observation, the inspectors noted that one control
      rod appeared to withdraw from the core abnormally f ast, and determined that drive
      water prewsure was still at an elevated level (approximately 400 psi), indicating that
      drive pressure was not returned to the normal range following successfulinitial
      movement. Additionally, operators did not return the drive water pressure to the
      normal range prior to selecting and withdrawing the next rod in sequence. This
      latter observation indicated that operators inappropriately remained M the stuch rod
      procedure without first meeting the prerequisite of unsuccessful control rod
      movement with normal drive water pressure. The inspectors questioned this
      practice because it appeared to be contrary to the noted proceduro guldance, and
      because continuous rod withdrawals from position 00 to 48 were being performed.
,
      The senior reactor operator (SRO) supervising the evolution stated that he felt
    justified in departing from the stuck rod procedure (both the prerequisites for usage
      and step 4.6 regarding the incrementalincreases in drive pressure) in part because.
      he was concerned that repeated cycling of the CRD pressure control valve was
    distracting his reactor operator from monitoring the source range count rate nuclear
    instrumentation. Further, the SRO stated that he " knew," based on experience, that
    every rod in the test sequence would require an elevated drive water pressure in
    order to be withdrawn. He further stated that the on duty operations
    superintendent also endorsed this practice. The reactor engineering department
    supervisor monitoring the evolution did not express a concern. The inspectors
    shared their observations with a quality assurance inspector also present in the
    control room but that individual did not independently pursue resolution of the issue
    with station management. Finally, no narrative log entries were made describing
    the basis for departing from the specific requirements of the abnormal operating
    procedure.
    The inspectors judged that operator's acted non-conservatively when they elected
    not to adhere to the requirements of the stuck control rod abnormal operating
    procedure, in that they permitted reactivity additions at potentially unknown or
    uncontrolled rates. Specifically, operators performed an infrequent evolution which
    added positive reactivity to an essentially now, untested reactor core with several
    new control rod blades using CRD mechanisms and hydraulic control units which
    had undergone either complete replacements or large scale maintenance, with their
    operability not yet fully demonstrated. Defense-in-depth from a potential fission
    product release was reduced since one of the principal barriers was degraded (i.e
    the vessel head was removed). The one rod-out interlock was defeated because the
    reactor mode switch was in "startup" to support performance of the test.
    Moderator temperature was below 100 degrees F, increasing core reactivity. The
    rod worth minimizer was inoperable and was being compensated by additional

                human oversight Collectively, the inspectors judged that these conditions 6Sould
                have warranted increased vigilance by reactor operators adding reactivity to the
                core, especially during an evolution that is designed to verify that the reactor will
                remain sufficiently ruberitical with twenty rods fully withdrawn.
                The inspectors reviewed other PSE&G procedures prescribing expectations for
                reactivity management and conservative decision making. The inspectors identified
                two procedures, NC.NA AP.ZZ 0005(O) (NAP 5) and HC.0P AS.ZZ 0002(Z), which
                provide guidance la these areas. Sections 5.21 and 6.30 of NAP-5 prescribe station    .
                                                                                                      '
                policy on the use of reactivity controls and specifies that personnel "act
                conservatively when f aced with adverse conditions which could affe-t reactor
                safety." The latter noted procedure, which is a specific Hope Creek operations
                department performance standard, requires operators to adhere to reactivity
                manipulation procedures " alertly and cautiously," and to move control rods in a
                " deliberate, :arefully controlled manner." The inspectors judged that the standards
                of performance defined in these two documents were not met during the November
                12,1997 shutdown margin demonstration.
                Until the inspectors discussed their observations with senior site management on
                November 13,1997, the significance of the noted issues went unrecognized by
                station personnel. Station management demonstrated an appropriate response to
                the issues, which included a formal debriefing with all of the station operators, and,
                initiation of a formal root cause and fact finding investigation. Memorandums
                reiterating expectations for maintaining " utmost caution" during reactivity
                manipulations were also issued. The responsible on shif t operations superintendent
                was reassigned to other duties.
                The inspectors noted that no actual safety consequences resulted from performance
                of the shutdown margin demonstration. Also, actual measured control rod speeds
                during the test were later determined to be within the analyzed envelope. However,
                plant eperation outside established reactivity manipulation procedures under the
                described circumstances reflected a poor operating practice and was judged to be
                an apparent violation of TS 6.8.1 procedure requirements. (eel 50 354/97 09 01)
          c.  Conclusions
                Operators exhibited poor performance during the conduct of an infrequently
                performed shutdown margin demonstration in that a stuck control rod procedure
                was not followed and conservative decision making with regard to reactivity
                management was not demonstrated. Additionally, these actions and decisions were
                not sufficiently challenged by control room observers.
          07    Quality Assurance in Operations
                The Quality Assurance (QA) departrnent conducted a detailed team review and audit
                of Hope Creek operations department performance with focus on technical
                specification (TS) implementation and action tracking during the report period. The
                inspectors observed portions of the audit and discussed relevant QA findings with
 
.

                                                  0
          lead oversight personnel. The QA team concluded that verbal communications,
          peer checking, infrequent evolution pre job briefs, and senior reactor operator
          oversight of control room activities were good. No improper operability
          determinations were identified. Howrver, the team Judged that procedure
          placekeeping and documentation, as well as TS action statement tracking, were
          weak. The team also concluded that there appeared to be a negative trend with
          respect to conservative decision making. Several examples, including the above-
          described shutdown margin demonstration issue, were used as a basis for reaching
          this conclusion. The inspectors judged that QA findings were well supported,
          independent, and promptly referred to station management for action.
  08    Miscellaneous Operations issues
  QL1 (Closed) LER 50 354/9713 01: unplanned high pressure toolant injection system
          inoperability. This event was described in detailin NRC Inspection Report 50-
          354/97 04 and resulted in issuance ci a violation of 10 CFR 50 Appendix B
          Criterion XVI. This supplemental LER was submitted to describe in greater detail
          the impact and significance of the event. Specifically, plant operators failed to enter
          TS 3.0.3 and commence a plant shutdown because the inoperability of the high
          pressure coolant injection (HPCI) system was not recognized during the period of
          time when two trains of the residual heat removal system were inoperable for on-
          line maintenance. The inspectors judged that the LER accurately described the

        Throughout the report period, the inspectors conducted frequent observations of
          station maintenance and surveillance activities to verify proper procedures were in
        use, adequate retests were completed or scheduled, monitoring and test equipment
          (M&TE) was within calibration, housekeeping and foreign material exclusion
          standards were satisfied, and coordination between departments was evident.
        Additionally, the inspectors reviewed PSE&G actions taken in response to self-
          identified or self revealing issues involving maintentnce or testing. A sample of
          safety-related equipment tagouts were evaluated for adequacy of development and
          implementation. Detailed assessments of specific observations and reviews are
        described in section M4.

                                    The inspectors observed inconsistent performance with respect to maintenance
                                    department activities. While most work orders reviewed spelfied adequate post-
                                    maintenance retest activities, some were noted to be deficient because the
                                    proposed tests were too narrowly focused. Though inspector verifications of
                                    equipment tagouts did not identify any deficiencies, several self identified "near-
                                    misses" were docurnented. Most observed maintenance was adequately supervised
                                    and coordinated between engineeri ,g and operations, however on one instance
                                    security grates were partially removed from circulating water system piping without
                                    prior notification of security personnel to ensure that appropriate compensatory
                                    measures were in place.
                                    Weld overlay repairs of the through wallleak on the NSB core spray nozzle were
                                    well planned, coordinated and executed. Underwater work in the primary
;                                  containment suppression pool to replace the *D" residual heat removal suction
                                    strainer was aiso well executed. Torus cleaning activities were judged to be
                                    excellent; the inspectors conducted an extensive pre closeout tour of the torus and
                                    found only minor deficiencies.
                                    Howover, several performance deficiencies were also noted. For example, foreign
                                                                                                                                                                                        ~
.
                                    material exclusion practices on the refuel floor were initially poor in that several
                                    objects were inadvertently dropped into the reactor cavity while the reactor vessel
                                    head was removed. Subsequent actions to improve performance in this area were
                                    effective, including more strict use of lanyards, tool controls, etc. A vital bus loss
                                    of power / loss of coolant accident surveillance test activity had to be repeated
                                    because maintenance technicians improperly set up the M&TE used for test data
                                    collection. Poor coordination with operations personnel during conduct of scram
                                    discharge volume (SDV) flushing resulted in the generation of an unexpected half-
                                    scum signal when water level exceeded SDV the trip setpoint.

                              c.    Conclusions
                                    Maintenance department technicians exhibited inconsistent performance during the
                                    conduct of outage work activities and testing. While procedure and work order
                                    usage was generally good, deficiencies in interdepartms. ital coordination and foreign
                                    material exclusion controls were evident.

    b. Observations and Findinas
        Following a scheduled electronic governor replacement, maintenance technicians
        began overspeed trip testing on the "B" EDG on September 27,1997. The
        technicians noted during restoration from the %st that the mechanical governor
        speed control adjustment, used during the o tspeed test, could not be returned to
        its original pre test setting. The entire mechanical governor assembly was then
        replaced based on a vendor recommendation, and the damaged unit was shipped
        offsite to a repair f acility. PSE&G reviewed the maintenance history on the *D" EDG
        mechanical governor and determined that the most likely failure of the speed control
        was an over adjustment of the speed knob on September 27,1997 con blned with
        inadequate tightening of internal governor dial stops in December 1994.
        On September 29,1997, two attempts were made to start the "B" EDG for post-
        maintenance testing af ter the mechanical governor replaccment. On both attempts
        the EDG tripped on low lube ol' pressure. PSE&G later determined that the initial
        setup of the new mechanical governor did not ellow the engine to develop sufficient
        speed to clear the low lube oil pressure trip. PSE&G subsequently developed a new
        procedure which provides guidance for performing initial diesel generator mechanical
        governor setups af ter maintenance or replacement (" Diesel Generator Speed / Load
        Control System Alignment," HC.MD CM.KJ-0015(O)h The inspectors learned that
        previous mechanical governor maintenance was conducted with direct oversight by-
        vendor representatives using work orders ind vendor technical references as
        guidance.
        On November 6,1997, following outage work, the "A" EDG was carrying the
        10A401 vital bus in accordance with " Integrated Emergency Diesel Generator
        1 AG400 Test 18 Months," HC.OP ST.KJ-0005(O). During the test, the control
        room operators discovered that the EDG would not respond to speed changes. The
        EDG was shut down and engineering personnel developed an action plan to
        troublesnoot the control problem. Technicians subsequently determined that the
        mechanical governor was improperly set, controlling the engine speed at too low a
        value which prevented the electronic governor from effecting speed changes.
        Further investigation by PSE&G determined that the speed knob on the mechanical
        governor was not restored to the proper position at the conclusion of an earlier
        overspeed test.
        The inspectors noted that none of the affected EDG's described above were
        required to be operable at the time of the maintenance or testing. Additionally, all
        of the applicable technical specification EDG surveillance tests were completed
        satisfactorily for each machine prior to restoring them to an operable status,
    c. Conclusions
        Namerous unplanned emergency diesel generator start attempts and equipment
        restoration delays were encountered as a result of weak work controls over
        mechanical governor maintenance and replacements.

                        The inspectors reviewed the maintenance conducted prior to and following a reactor
'
                        core isolation cooling (RCIC) system turbine overspeed trip event du'ing testing,
                b.    Observations and Findinos
                        On November 9,1997, with the rtuctor plant in operational condWnn 6,
                        maintenance technich.ns attempted to perform an overspeed trip test of the RCIC
                        turbine using auxiliary steam in accordance with procedure HC.MD PM.FC 0001(O),
                        * Reactor Core isolation and Cooling Steam Turbine Inspection and P.M." The pre.
                      Job brief for the evolution was good in that Individuals were assigned specific
4                      actions should unforeseen e.ircumstances arise during the test. As required, the              t
                                                                                                                      '
                        turbine was uncoupled from the pump and turbine speed was controlled from a local
                        potentiometer and was raised in 50 rpm increments, with an overspeed trip                      t
                        expected at approximately 5625 rpm. At 4900 rpm, the RCIC turbine unexpectedly                ;
                        accelerated to about 7500 rpm. A maintenance technician in the RCIC room
                        immediately tripped the turbine with the local trip device after recognizing the
,
                        overspeed condition, as assioned during the pre job brief. The RCIC system was
                        not required to be operable at the time of the test.
                      The inspectors judged the PSE&G's troubleshooting plans and follow up actions to
                      the overspeed event to be adequate. Based in part on vendor recommendations,
                        RCIC turbine inspections were conducted to verify that the no equipment damage
                      resulted. PSE&G determined that one of the causes of the event was that the
                      mechanical overspeed trip device was not properly set up during the previous
                        system maintenance, primarily bucause the work procedure did not provide
                        sufficient detail to ensure consistent implementation. PSE&G revised the HC.MD-
                      PM.FC 0001(Q) procedure to include a detailed verification that the mechanical
                      overspeed trip device is properly set prior to operating the turbine. Engineers
                      determined the most likely cause of the overspeed event, aside from the failure of              '
                      the trip mechanism, was air entrapment in the turbine governor control oil following
                      a filter change. PSE&G enhanced the RCIC turbine operating procedures by adding
                      additional oil system venting activities to minimize the potential for air introductlen
                      during RCIC operation.
                c.    Conclusions
                      Maintenance technicians improperly set up the mechanical overspeed trip device for
'
                      the RCIC turbine in part due to weak procedural guidance, which complicated a
                      subsequent turbine overspeed event, insufficient venting of the turbine control oil
                      wystem, again partly because of limited procedure guidance, was judged to be the
                      primary cause of the overspeed event.

        destructive examination and repair.
  a.  htmgetion Scoce (73115)
        This inspection was conducted as a followup to an issua 8M' unresolved following a
        recent inservice inspection program assessment. The W          ..ivolved the f ailure to
        identify degradation prior to the development of a through wallloak in the NSB core
        spray nozzle to safe end weld. The process employed to repair the lock (weld
        overlay with .emperbead welding) on the low alloy steel nozzle was also reviewed.
  b.  Q32servations and Findinos
        The inspectors reviewed PSE&G's formal root cause evaluation report for the NSB
        core spray injection nozzle through-wallleak, dated November 4,1997, af ter
        meeting with some of the participants on the evaluatio.: team. The inspectors
        found ti at extensive fact gathering and root cause analysis were performed with
        appropriate corrective actions either proposed or implemented. The safety
        significance of the degraded NSB weld were discussed in the report, which stated
        that there were no actual consequences and that there was no impact on public
        health and safety. Though an increass in unidentified drywellleakage (from 0.3 to
        0.0 gallons per minute) was noted in August 1997 during plant operation, this
        increased leakage was withh TJ limits and was not associated with an increase in-
        radiation. Because the crack exhibited the * leak before break" behavior expected
        for the materials of construction, any further crack propagation with the plant
        operating would have resulted in an increased unidentified leak rate followed by a
        normal plant shutdown prior to a catastrophic pipe f ailure. Postulation of
        consequences of the worst case event, that is a failure of the core spray line
        initiated by a transient (e.g. seismic event) was evaluated by the PSE&G engineers
        and found to be within the plant's design and licensing bases.
        PSE&G identified one of the causal f actors of this issue was ineffective computer-
        based ultrasonic testing (UT) dats evaluation. Recent re review of 1995 UT data
        identified a misdiagnosed degrav'.d condition to have been present in 1995. The
        1995 UT analyst noted the presence of a recordable indication, but judged that
        there was no requirement for either supplemental non destructive examination (NDE)
        or UT examination of the area containing the indication. PSE&G's recent review of
        UT data on 19 other similar welds, including the conduct of UT on six of these
        welds in 1997, did not identify any similar problems. On another set of 16 welds
        that were examined by the somo UT process as the NSB weld, a reexamination of
        six of these in 1997 by manual UT did not identify degradation. Other than the NSB
        wold UT problem, no other incidents of a f ailure to identify potentially significant
        flaws were found.
        The 1995 UT analyr t dispositioned the NSB weld indication as acceptable based on
        the nozzle weld data provided which indicated that the material was INCONEL 82
 
.
B
                                                    11
          and was therefore not susceptible to stress corrosion cracking. During the
          licensee's root cause analysis, it was determined that the construction material
          should have been recorded as INCONEL 182 which is susceptible to cracking.
          Immediate corrective actions to resolve the through-wallleakage included the repair
          of the NSB weld by weld overlay. The corrective actions directed toward improving
          the effectiveness of UT of welds similar to NSB included specific instructions to
          Level 111 UT examiners for dissimilar welds, procedure reviews to clarify data
          interpretation actions, industry involvement to improve UT of dissimilar welds,
          additional review of causes and corrective actions, requirement for indepeMent
        review of UT data by a second analyst for category D welds, consolidatice nd
          review by data analysts of as-built data for each weld, and review of site specific
          flaws and reflectors by the data analysts prior to review of new NDE data.
        The failure to promptly idenufy the degraded core spray nozzle weld in 1995, a
        condition adverse to quality, coupled with the f ailure to reques supplernental
        nondestructive evaluation or supplemental ultrasonic examination of the area when
        the indication was initially discovered, represented an inadequacy in the inservice
          inspection program. As such, this event was deemed to be a violation of 10 CFR
          50 Appendix B, Criterion XVI Corrective Action. However, because this violation
        was non repetitive, and because of the prompt and thorough development of root
        causes and corrective actions, thlF violation is being treated as a Non-Cited
        Violatiore, consistent with Section Vll.B.1 of the NRC Enforcement Policy (NUREG-
          1600). (NCV 50 345/97 09 02)
    c.  Conclusions
        PSE&G performed a detailed and thorough evaluation of the failed core spray nozzle
        weld history, previous nondestructive testing, and through wall leak causal f actors.
        Proposed corrective actions were judged to be reasonable and appropriately focused
        on preventing recurrence. However, the failure to detect and repair a weld flaw in
          1995 during a focused ultrasonl< inspection of the noted core spray nozzle
        highlighted weaknesses in th.: Hope Creek inservice inspection program.

        described in dew in NRC Inspection Report 50-354/97 07 and was left unresolved
        pending an NRC assessment of the completed root cause evaluation for why
        analyses of a previot3.nna.t nic tes't of this nozzle failed to detect a weld flaw.
        This assessment was wu sh I during the current report period with the results

                            August 17,1997, because of a recent surveillance tcat procedure change which
                            was deficient. Specifically, the FRVS test procedure was recently modified to
                            change the method used to verify heater power consumption at the end of a ten
                            hour heater run. However, no provision was included to allow the f an to run after
                            the heaters were deenergized to cool the coils. As such, when the unit ,is secured
                            following the August 17 test, the heater high-high temperature switch unsnowingly
                            tripped, rendering the unit inoperable. PSE&G recognized in t.'to LF.R discussion that
                            because the FRVS unit was inoperable for greater than sev',n days ithe TS allowed
                            outage time for one inoperable FRVS unit), the plant should have commenced a
                            shutdown on August 24,1997.
                          The inspectors verified that the FRVS surveillance test procedure was appropriately
                          revised following identification of this issue and that subsequsnt FRVS test runs
                          have not experienced any similar problems. This licensee-identified and corrected

                          The inspectors reviewed PSE&G's actions in response to a self identified discovery
                          of three jet pump sensing line bracket weld cracks,
                    b.    Observations and Findinas
                          Oming in-vessel visual inspections of jet pumps, PSE&G inspectors determined that
                          rn pump numbers 8,9, and 15 all exhibited instrument line bracket weld cracks
                          v nich required repair. Station engineering personnel proposed the use of
                          " temporary" clamps to secure the affected sensing lines rather than repair the
                          deficient welds. Hope Creek staff also performed comprehensive inspections of all
                          20 jet pumps, including the lower elbows next to the inside of the vessel where
                          cracking had been recently discovered at the Peach Bottom Atomic Power Station
                          (GE-BWR4). No cracking was noted in these areas at Hope Creek.
                          A conference call between NRC and PSE&G technical staff was held on November
                          14,1997 to discuss the issues related to the proposed jet pump clamp repair
                          methodology. The clamp design was developed for use at the Susquehanna Steam
                          and Electric Station (GE-BWR4) where similar jet pump instrument line bracket weld

                    course of the conference call.
                    The inspectors reviewad the design change package and associated evaluation for
                    installation of the jet pump clamps, and judged them to be acceptabla. Additionally,
                    thi inspectors observed portions of the actual clamp installation process, including a
                    review of the installation procedure, and did not identify 6ny deficiencies. Based on
                    the results of future refu(I outage inspections of these cumps, these jet pump
                    modifications may become a permanent installation.
                c.  Conclusiong
                    PSE&G promptly developed and implemented an acceptable design change pa::kage

.              Q1 Desian Chanae Packsae and Safetv Evaluation Review
                a.  Insoection Scoce (37551)
                    The inspectors reviewed the 10 CFR 50.59 safety evaluations associated with the
                    following plant system design modifications implemented during this report period:
                    * lsofoam in the turbine auxiliaries cooling system (TACS) accumulator floating roof
                    * Ultrasonic Test Scanner bearing cap - potentiallost part in reactor vessel
                    * Alternate air supply to SACS flow control valve for safety-related chiller units
                    * Re route service water vacuum breaker piping from secondary containment
                    Additionally, the inspectors observed the installation of several other engineering
                    design change packages needed before the restart from the RF07 refuelinr, outage,
                    including:
                    * Emergency core cooling system suppression pool suction strainer modifications
                    * Jet pump instrument line clamps
                    * Rod sequence control system elimination
                    * Reactor recirculation pump mechanical seal cartridge upgrade
.
                b.  Observations and Findinas
                    PSE&G engineering developed approximately 70 design change packages for
                    installation during the RFO7 refueling outage, several of which were not part of the
                    original outage work scope but were deemed necessary as a result of self identified
                    adverse or degraded conditions. For instance, a safety evaluation was prepared on
                    November 12,1997, to assess the impact of plant operation with an unrecovered
                    loose part in the reactor vessel. Specifically, a 1" x 2" steel bearing cap which had
                    fallen ' ff an ultrasonic testing rig used for in-vessel weld inspections was never

          recovered despite extensive efforts to locate and retrieve the item. The safety
          evaluation thoroughly assessed the potential concerns associated with this lost part,
          including possible effects on control rod movement, core flow restrictions, etc., and      ,
          judged that even though the issue involved a " change" to the facility as described ir,
          the UFSAR,it did not result in the need for prior NRC review and approval.
          Several other engineering saf sty evaluations were reviewed and judged to be
          acceptable.10 CFR 50.59 " applicability reviews" and unreviewed safety question
          determinations included sufficient scope, detail and analysis to justify tha final
          conclusions. The inspectors determined that none of the plant modifications
          reviewed resulted in final installed conditions which were inconsistent with.
          continued safe plant operation. In fact, most of the 70 change evaluations
          completed during the outage were developed to enhance safe and uneventful plant
          operation, as opposed to simply accepting degraded conditions "as is" or providing
.
          for operational conveniences.                                                              ,
          Based on the limited sample of evaluations reviewed, the inspectors judged that the
          quality of the 10 CFR 50.59 process had improved over the past operating cycle.
          Process improvements such as evaluation " grading," cross disciplinary peer
          roviewing, independent auditing, and focused engineering department training
          resulted in better and more thorough safety evaluations. Based on interviews with
          engineering management personnel, the inspectors learned that the process will
          continue to evolve based on recently issued regulatory and industry guidanco,
      c.  Conclusions
          Engineering department prepared safety evaluations were of good quality and were
          appropriately focused on the potential nuclear safety impact of the r! ant design or
          equipment changes.
    E8    Miscellaneous Engineering issues
    EQJ fClosed) LER 50-354/96-09: operation in an unanalyzed condition due to
          inappropriate service water system / safety auxiliaries cooling system throttle valve-
          settings. This LER describes a self-identified issue involving a March 1996
          discovery that station service water (SSW) system throttle valves were set
          improperly in November 1992 after a design change which replaced these valves,
          that would have prevented adequate SSW cooling flow to the safety auxiliaries
          cooling system (SACS) heat exchangers during design basis accident conditions.
          PSE&G recognized that while no safety consequence resulted from this failure to
          maintain appropriate system configuration control, the plant was operated for nearly
          four years outside of the design and licensing basis (see NRC Inspection Report 50-
          354/96 06). PSE&G attributed the cause of this deficiency to an inadequate
          engineering design modification process, which in 1992 did not require design
          calculation assumptions to be verified by field data collected after modification
          installation.

                                                      15
          The inspectors determined that PSE&G's design change process was modified to
          include the need to conduct field verifications of design calculation assumptions.
          Additionally, PSE&G conducted a thorough design bases validation of the SSW and
          SACS systems by performing an independent service water system operational
          performance inspection, an NRC review of which was documented in NRC
          inspection Report 50-354/97-06. Lastly, in direct response to the issue described in
          this LER, on October 23,1996, the NRC issued a violation of TS 3.7.1.2.b, which
          requires that an operable service water flow path be maintained to ensure adequate
          cooling to the SACS heat exchangers (see section E8.6 below).
    kBJ (Closed) LER 50 354/9615: potential to operate in an unanalyzed condition due to
          a design deficiency in the (service water emergency) overboard discharge line.
          During station service water (SSW) system design bask reviews performed in
          response to previously identified discrepancies, engineering personnel identified an
          error in SSW design calculations in that emergency discharge point dynamic flow
          conditions were not properly accounted for. This discovery rendered the technical
          specification (TS) limit on maximum ultimate heat sink (UHS) temperature non-
          conservatively high (see NRC inspection Reports 50 354/96 04,96 06, and 97-01).
          A public meeting between the NRC and PSE&G was held on July 18,1996, to
          discuss this and other related SSW and SACS system design issues, as well as
          instituted compensatory measures and proposed corrective actions. Compensatory
          measures included placement of an administrative limit on maximum UHS
          temperature and development of specific operator actions in the event of a loss of
          one SSW or SACS loop. Corrective actions included the conduct of an independent
          service water system operational performance inspection, followed by the submittal
          of any needed license change requests.
          PSE&G completed its SSW/ SACS / UHS design basis review in May 1997, and
          submitted associated TS amendment requests for NRC review promptly thereafter.
          An independent NRC inspection of the design basis review effort was documented
          in NRC Inspection Report 50 354/97-06. NRC review of PSE&G-proposed licenso
          changes was completed in October 1997, and were issued as TS Amendment 106.
          The NRC safety evaluation report included with this amendment did not identify any
          concerns with the PSE&G-proposed changes.
    EDJ (Closed) LER 50-354/97-24:as found values for safety relief valvo lift setpoints
          exceed technical specification allowable limits. This LER was written to document a
          repeat issue involving main steam line safety relief valve (SRV) setpoint drift outside
          technical specification (TS) limits. As found " bench testing" of the 14 Hope Creek
          SRV's, which are a two-stage Target Rock design, determined that ten of the valves
          had excessive drift (worst case was + 9.4%). The setpoint drift issue has been an
          on-going industry-wide concern and several industry-driven corrective actions have
          been proposed. The inspectors determined that PSE&G has been aggressively
          pursuing resolution of this issue, which has included design changes to SRV pilot
          valve seating materials. All SRV setpoints wera verified to be within TS allowable
          drif t limits prior to reinstallation in the main steam system.

  EBA (Closed) LER 50 354/97 25: design deficiency potential for an unmonitored release
        path through the station service water system. This LLR describes a self identified
        discovery of a potential secondary containment bypass leakage pathway. After a
        postulated loss of power accident, station service water (SSW) system solenoid-
        operated vacuum breakers would fall open allowing the reactor building atmosphere
        to communicate directly with SSW piping, which discharges water outside the
        secondary containment. This design deficiency was recognized by technicians
        performing maintenance on the noted sotenoids. PSE&G promptly developed a
        design change packagt to re-route the vacuum breaker vent piping to the outside
        environment rather than from inside the reactor building. The inspectors reviewed
        the design change package and the associated safety evaluation, es well as walked
        down the modified piping after installation was complete. No defic!sncies were
        noted. The inspectors judged that PSE&G acted promptly and effectively in the
        resolution of this issue.

        for several compensatory measures to be put in place to ensure that the ncted

        inspectors verified that corrective actions stated in PSE&G's violation response
        letter dated November 22,1996, were completed. These actions included (1) a
        comprehensive service water system flow balance in which engineering flow
        calculation assumptions were validated with field data, (2) the engineering process
        for making design modifications was enhanced with additional specific training

        A focused review was performed to determine whether the PSE&G security
        program, as implemented, met the licensee's commitments in the NRC-approved
        security plan (the Plan) and NRC regulatory requirements. The security program
        was inspected during the periods of November 3-7 and November 12,1997. Areas
        inspected included: management support; audits; alarm stations, communications,

                    Management support was ongoing as evilenced by the procurement and installation
                    of four X ray machines for access searco * packages, installation and
                    implementation of hand geometry, and range upgrades to enhance tactical response
                    training. Audits were thorough and in depth, alarm station operators were
                    knowledgeable of their duties, communications requirements were performed in
                    accordance 'vith the Plan, and assessment aids had adequate picture quality.
                    Vehicles requiring protected area access were controlled as required in the Plan.
                    Applicable procedures and security equipment were tested and maintained in
                    accordance with the Plan, and security training was performed in accordance with
                    the NRC approved training and qualification (T&O) plan.
                    Based on the observations and discussions with security management and plant                "

i                  inspector observations of CAS and SAS operations verified that the alarm stations
                    were equipped with the appropriate alarm, surveillance, and communication
                    capabilities. Interviews with CAS and SAS operators found them knowledgeable of
                    their duties and responsibilities. The inspectors also ver!fied through observations    ;

                    and interviews that the CAS and SAS operators were not required to engage in
                    activities that would interfere with the assessment and response functions, and that
                  .the licensee had exercised communication methods with the local law enforcement
                    agencies as committed in the Plan.

                    Tht, inspectors reviewed testing and maintenance records for security related
                    equipment and found that documentation was on file to demonstrate that the
                    licensee was testing and maintaining systems and equipment as committed to in the
                    Plan. A priority status was being assigned to each work request and repairs were
                    normally completed the same day a work request necessitating compensatory
  i                measures was generated. The inspectors also noted that the working relationship
                    between security and maintenance departments was improving and tracking and
                    trending programs to monitor recurring equipment problems to determine when
,
                    engineering support was required, were being implemented.

    S5      Security and Safeguards Staff Training and Qualification
      a.      insoection Scone
              The inspectors evaluated whether members of the security organization were
              trained and qualified to perform each assigned security related job task or duty in
              accordance with the NRC approved T&Q plan,
      b.    Observations and Findinas
              On November 5,1997, the inspectors randomly selected and reviewed the T&Q
              records of thirteen security force members (SFMs). Physical and firearms
              requalification records were inspected for armed SFMs and security supervisors.
              The inspectors found that the training had been conducted in accordance with the
              T&Q Plan and was properly documented.
              During discussions with the security training staff and security management, the                ;
              inspectors were informed that new response weapons were purchased to enhance                    l
              the licensee's tactical response capabilities. However, the new weapons will not be            l
              issued until all SFMs have been properly trained and qualified with the new
              weapons. Further discussions revealed that the licensee was in the process of
              upgrading its firing range. On November 6,1997, the inspectors toured the firing
              range and determined, based on observations, that the upgrades would enhance
              tactical response training. Additionally, the inspectors interviewed a number of
'
              SFMs to determine if they possessed the requisite knowledge and ability to carry
              out their assigned duties,
      c.    Conclusions
              The inspectors determined that training had been conducted in accordance with the
              T&Q plan. Based on the security force members responses to the inspectors *
              questions and observations, the training provided by the security staff was
              considered effective.

                          procurement and installation of four X ray machines for access search of packages,
                          and installation and implementation of hand geometry and range upgrades to
                          enhance tactical response training.
                          The inspectors reviewed the Manager - Nuclear Security's position in the
                          organizational structure and reporting chain. The Manager - Nuclear Security
                          reports to the General Manager Salem Operations, who reports directly to the
                          Senior Vice President - Nucleer Operations, who reports directly to the Chief Nuclear
                          Officer and President Nuclear Business Unit.

                          Management support for the physical security program was judged to be effective.
                          No problems with the organizational structure that could be detrimental to the
                          effective implementation of the security and safeguards programs were noted.

              S2d Audits
                  a.      Insnection Sco.ag
                          The inspectors reviewed the licensee's Quality Assurance (QA) report of the NRC-
                          required security program audit to determine if the licensee's commitments as
                          contained in the Plan were being satisfied,
                  b.      Observations and Findinas
                          The inspectors reviewed the 1997 combined QA audit of the security, access
                          authorization and fitness for-duty (FFD) programs, conducted May 19-30,1997,
                          (Audit No. 97-031). The audit was found to have been conducted in accordance
                          with the Plan and FFD regulation. To enhance the effectiveness of the audit, the
                          PSE&G's QA audit team included four independent technical specialists.
                          The audit included findings in the security, access authorization and FFD areas,
                          however, the inspectors determined that the findings were not indicative of major
                          programmatic weaknesses. The inspectors further determined, based on
                          discussions with security management and FFD staff and a review of the responses
                          to the findings, that the resultant corrective actions were effective.
                  c.      Conclusions
                          A recent Quality Assurance Audit of security was very comprehensive in scope and
                          depth, and at,dit findings were reported to the appropriate levels of management.
                          The inspectors judged that the audit program was being effectively administered.

    88    Miscellaneous Security and Safeguards issues
    Sfld Vehicle Barrier System (VBS)
            General
            On August 1,1994, the Commission amended 10 CFR Part 73, " Physical Protection
            of Plants and Materials," to modify the design basis threat for radiological sabotage
            to include the use of a land vehicle by adversaries for transporting personnel and
            their hand carried equipment to the proximity of vital areas and to include the use of
,
            a land vehicle bomb. The amendments required reactor licensees to install vehicle
            control measures, including VBSs, to protect against the malevolent use of a land
            vehicle. Regulatory Guide 5.68 and NUREC/CR-6190 were issued in August 1994
            to provide guidance acceptable to the NRC by which the licensees could meet the
            requirrments of the amended regulations.
            Letters dated February 28,1996 and June 19,1996 from PSE&G to the NRC
            forwarded Revisions 6 and 7 to its physical security plan that detailed the actions
            implemented to meet the requirements of 10 CFR 73.55 (c)(7),(8), and (9) and the
            design goals of the " Design Basis Land Vehicle" and " Design Basis Land Vehicle
            Bomb." A NRC July 6,1996, letter advised the licensee that the changes
            submitted had been reviewed and were determined to be consistent with the                  .
            provisions of 10 CFR 50.54(p) and were acceptable for inclusion in the NRC-
            approved security plan.
            This inspection, conducted in accordance with NRC Inspection Manual Temporary
            Instruction 2515/132," Malevolent Use of Vehicles at Nuclear Power Plants," dated
            January 18,1996, assessed the implementation of the licensee's vehicle control
            measures, including vehicle barrier systems, to determine if they were
            commensurate with regulatory requirements and the licensee's physical security
            plan.
          The inspectors reviewed documentation that described the VBS and physically
            inspected the as-built VBS to verify that it was consistent with the licensee's
            summary description submitted to the NRC. The inspectors' walkdown of the VBS
            and review of the VBS summary description disclosed that the as-built VBS was
            consistent with the summary description and met or exceeded the specifications in
            NUREG/CR-6190. The inspectors determined that there were no discrepancies in
            the as-built VBS or the VBS summary description.
    $12 Bomb Blast Analysis
          The inspectors reviewed the licensee's documentation of the bomb blast analysis
            and verified actual standoff distances provided by the as-built VBS. The inspectors'
            review of the licensee's documentation of the bomb blast analysis determined that
            it was consistent with the summary description submitted to the NRC. The
            inspectors also verified that the actual standoff distances provided by their as-built
          VBS were consistent with the minimum standoff distances calculated using
                        __            _            _.
 
    .-            -        - -                                -      . -  _                    . -. .

                                                        22-
'
                NUREG/CR-6190. The standoff distances were verified by review of scaled-
                drawings and actual field measurements. No discrepancies were noted in the
                documentation of bomb blast analysis or actual standoff distances provided by the
                as-built VBS.
,      ESJ Procedural Controls
                The inspectors reviewed applicable procedures to ensure that they had been revised
                to include the VBS. The inspectors reviewed the licensee's procedures for VBS
                access control measures, surveillance and compensatory measures. The procedures
                contained effective controls to provide passage through the VBS, provide adequate
                surveillance and inspection of the VBS, and provide adequate compensation for any
                degradation of the VBS. The inspector's review of the procedures applicable to the
                VBS disclosed no discrepancies.

        X1      Exit Meeting Summary
        The inspectors presented their findings and conclusions to members of licensee
        management at the conclusion of the report period on November 21,1997. The licensee
        acknowledged the findings presented.
        The inspectors asked the licensee whether any materials examined during the inspection
        should be considered proprietary. No proprietary information was identified.
        X2      Review of Updated Finst Safety Analysis Report (UFSAR)
        A recent discovery of a licensee operating its f acility in a manner contrary to the UFSAR
        description highlighted the need for a special focused review that compares plant practices,
        procedures, and parameters to the UFSAR description. Since the UFSAR does not
        specifically include security program requirements, the in:;pectors compared licensee
        activities to the NRC approved physical security plan, which is the applicable document.
        While performing the inspection discussed in this report, the inspectors reviewed
        Section 4.1.2 of the Plan, titled " Protected Area - Physical Barrier Description" was
        reviewed. The inspectors determined, by observations, that the protected erea barrier was
        properly installed, maintained and satisfied the requirements of the Plan.

EXECUTIVE SUMMARY

, Hope CreJk Generating Station

NRC Inspection Report 50 354/97 09

'

j

] This integrated inspectior. includes aspects of licensee operations, engineering,

maintenancc, and plant support. The report covers a six week period of resident -

inspection; in addition, it includes the results of announced inspections by three regional .

inspectors, one who reviewed PSE&G follow up activities to the core spray norzle through j

wallleak event and two who evaluated the effectiveness of site security programs and i-

-

practices.

! QacIations 1

!

Operators demonstrated inconsistent performance overall, and exhibited notable

.

- weaknesses with respect to attention to detail and awareness of equipment status. i

4

(Section 01.1)  !

PSE&G personnel displayed excellent overall performance in the development, pre bricling,

, and implementation of the plan to drain down the reactor cavity and vessel to support core

]

- spray nozzle repair efforts. (Section 01.2) ,

Operators exhibited poor performance during the conduct of an infrequently performed l

shutdown margin demonstration in that a stuck control rod procedure was not followed  ;

and conservative decision making with regard to reactivity management was not

4 demonstrated. Additionally, these actions and decisions were not sufficiently challenged

by control room observers. (Section 04.1)

,

The inspectors judged that Quality Assurance findings were well supported, independent,

-

and promptly referred to station management for action. Quality Assurance oversight of

control room activities was usua'ly good. (Section 07)

Maintenance  ;

!

- Maintenance department technicians exhibited adequate performance during the conduct of

outage work activities and testing. While procedure and work order usage was generally

good, deficiencies in interdepartmental coordination and foreign material exclusion controls

were evident. (Section M1.1)

Numerous unplanned emergency diesel generator start attempts and equipment restoration

delays were encountered as a result of poor work centrols over mechanical govemor

maintenance and replacements. (Section M4.1)

Maintenance technicians improperly set up the mechanical overspeed trip device for the 4

. reactor core isolation cooling turbine in part due to weak procedural guidance, which

complicated a subsequent tutbine overspeed event. Insufficient verting of the turbine

control oil system, again partly because of limited proceduro guidance, was judged to be

the primary cause of the overspeed event. (Section M4.2)

,

PSE&G performed a detailed and thorough evaluation of the f ailed core spray nozzle weld

j history, previous nondestructive testing, and through wallleak causal f actors. Proposed-

corrective actions were judged to be reasonable and appropriately focused on preventing

recurrence. However, the f ailure to detect and repair a weld flaw in 1995 during a focused i

ultrasonic inspection of the noted core spray nozzle highlighted weaknesses in the Hope  ;

Creek inservice inspection program. (Section M8.1) i

inadequate surveulance test procedure development led to the undetected inoperability of

,

one train of the filtration, recirculation, and ventilation system. Corrective actions were  ;

-

effective. (Section M8.3)

Enaineerina -

PSE&G promptly developed and implemented an acceptable design cho. ige packege to  !

resolve a self identified issue involving bracket weld cracks on jet pump instrument lines. l

(Section E1.1)  !

Engineering department prepared safety evaluations were of good quality and were

appropriately focused on the potential nuclear safety impact of the plrnt design or

equipment changes. (Section U2.1)

PSE&G acted promptly and effectively in the resolution of a self identified issue involving a

potential secondary containment bypass leakage pathway. (Section E8.4)

'

!

Plant Suonort

PSE&G maintained an effective site security program. Management support of program

'

objectives was evident. Performance of security department person.nc! cnd equipment

were generally good.

,

PSE&G's provisions for land vehicle control measures satisfied regulatory requirements and

licensee commitments. The site protected area barrier was properly installed and

maintained, and satisfied the requirements of the NRC approved security plan.

01 Conduct of Operations

.

QM General Observatlora

a. jnsocution Scone 171707)

Throughout the report period, the inspectors routinely reviewed and obserwd

operator performance with respect to technical specification (TS) action statement

tracking, proceduto compliance, attention to detail, and reportable event accuracy

and timeliness. Quality assurance (OA) efforts were also assessed.

b. Qb.tmiyations and Findinas

The inspectors witnessed inconsistent performance by operators during their

conduct of routine and off normal activities. For example, reactor fuel reload

activities were executed very well, in contrast to the offload activities earlier in the

outage. All fuel moves were performec'in a single dimension, and no errors were

noted in bundle selection or placement. As noted in section 01.2 below, efforts

involving the reactor cavity drain down were conducted effectively. Shutdown

cooling and spent fuel pool decay heat removal system flow paths were closely

controlled and protected. Control room operators were generally f amiliar with most

work being conducted in the plant.

OA inspector coverage in the control room was frequent and provided generally

good independent assessment of plant activities. Of particular note, a OA inspector

questioned operators on whether a decision to commence core alterations

(operational condition') from operational condition 5 was consistent with TS 3.0.4

since two trains of the filtration, Iacirculation and ventilation system (FRVS) were

inoperable. TS 3.0.4 mandates that entry into an operational condition shall not be

made when conditions for the limiting conditions for operation (LCO) are not met

and the associated action statement ultimately requires a plant shutdown. The

FRVS TS 3.6.5.3 LCO requires that all six FRVS recirculation units be operable in

operatii, ial condition'. Because of OA intervention in this issue, a potential TS

violation was avoided during the operational condition change.

The inspectors noted other performance deficiencies during the report period.

Specifically, on November 7,1997, relieving operating shitt personnel questioned

off going operators about the status of the safety parameter display system. At

that point off going operatorr reallred that the system had been inoperable for

nearly 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, since the degraded condition was first identified and

communicatsd to engineering personnel for resolution earlier in their shif t. Operators

appropriately recognized that this condition required a non-emergency 10 CFR

50.72 report to the NRC as a " major loss of emergency assessment capability" in

accordance with the Hopa Creek emergency classification guide. Operations

management concluded that this reportable event resulted from inadequate

turnovers, follow up, and communichtions.

Othat weaknesses were identified as well. A loss of offsite power / loss of coolant

accident (LOP /LOCA) surveillance of the *B" 4100 VAC vital bus had to be rapeated >

when the *B" residual heat removal system pump failed to start because the motor

supply breaker switch was inadvertently lef t in " pull to lock." Implementation of

several test procedures, including a reactor core isolation cooling system valve

inservice test procedure observed by the inspectors, did not meet department

expectetions for placekeeping. A reactor auxiliaries cooiing system head tank

overflowed while troubleshooting continued on an emergency diesel generator  ;

control system because operators did not maintain full cognizance of system status.

Though not anticipated, a service water pump automatically started as designed i

during a remote shutdown panel test because the pump controls were left in

automatic during the activity. While performing core alterations, secondary

containment pressure went positive with respect to atmospheric conditions during

recovery from a LOP /LOCA surveillance when a reactor building ventilaCon

subsystem tripped. The unreliability of this subsystem had been demonstrated by

earlier unexplained trips, and caused the inspectors to question the decialen (af ter

the f act) to continue fuel movements during the noted LOP /LOCA tert.

c. C,onclusiont

Operators demenstrated inconsistent performance overall, and exhibited notable

weaknesses with respect to attention to detail and awareness of equipment status..

Quality assurance oversight of control rooms activities was usually good.

QL2 Reactor Cavity and Vessel Drain Down Evolution

a. Impection Scope (71707)

The inspectors observed portions of the planning, briefing, and implementation of a

first time evolution involving a reactor cavity and vessel drain down to suoport weld

repair efforts on the "A" core spray line nozzle.

b. Observations and Findinos

Weld repairs for the through wallleakage on the "A" core spray nozzle (see NRC

Inspaction Report 50 354/97 07 for details) required that the vessel penetration be

drained of water. Because this penetration is not isolable from the reactor vessel,

operators devised a plan for draining the cavity and vessel to a level below the

nozzle to support the work. The reactor fuel bundles were completely offloaded

into the spent fuel storage pool. The inspectors reviewed the newly prepared

procedure, which was in part based on other industry experience, and jedged it to

be of good depth and quality. PSE&G completed thorough reviews of the

procedure, which included a final approval by the station operations review

committee.

The pre evolution briefing was timely and comprehensive, and was attended by a

wide array of direct and peripheral evolution participants. Contingency measures

were thoroughly discussed, and effective communications were stressed.

'

Because the entire core had been transferred to the spent fuel storage pool,

operators planned a functional test of the residual heat removal fuel pool cooling

assist mode bnfore the fuel pool getes were installed. The inspectors observed the

functional terit, an activity which had not been perforrned since Hope Creek pre-

operational testing. Based in part on a prior detailed procedure walk through, the  ;

test was completed without error or incident.

Operators properly conducted the drain down evolution using the newly developed

procedure. Appropriate actions were taken upon discovery that the equipment pool

gate seals were leaking water at a rate of several hundred gallons per minute, ,

Oulck recognition and timely response !n accordance with pre planned contingencies

and briefings ensured that no additional complications were encountered. The gate

seals were repairet, and the drain down was completed successfully. The

inspectors witnessed excellent management oversight and interdepartmental l

coordination during this activity. +

c. Conclu11ong

PSE&G personnel displayed excellent overall performann ir* the development, pre-

bilefing, and impleninntation of the plan to drain down the reactor cavity and vessel

to support core spray norrie repair efforts.

04 Operator Knowlvdge and Performance ,

QL1 Shutdown Maroin flamonstration

a. ADippetion Scone U1707)

The inspectors observed portions of a post refueling reactor shutdown margin

demonstration performed to demonstrate compliance with technical specification 3.1.1.

b. Observations and Findinas

On November 12,1997, with the plant in operational condition 5 (reactor vessel

head removed). control roon, operators began a core shutdown margin

demonstration in accordance with procedure HC.RE ST.ZZ 0007(O). This test  ;

'

involved the full withdrawal of twenty control rods (of 185 total) selected by the

reactor engitioering .tarf. Operamrs invoked "special test exception" TS 3.10.3 to

permit conduct of this infrequently p9rformed svolution since the test required the

mode switch to be placed in the **.tartup" pc ition, defeating the one-rod out

interlock normally required le operational condition 5. The inspectors verified that all

associated TS required conditions were satisfied during performance of the test,

which included reactor protection system (RPS) shorting link removal and the need '

fo % dependent oversight and verification of test procedure compliance by a

" technically qualified member of the staff," in this case the reactor engineering

department supervisor, since the rod worth minimiter was inoperable.

_ _-, __ - . - - . _. __

Operators experienced difhculty withdrawing several of the test-designated control

rods. As cuch, early in the evolution during an initial observation, the inspectors ,

noted that operators appropriately implemented step 4.6 of the stuck control rod l

procedure, HC.OP AB.ZZ 104(O), which requires that control rod drive (CRD)

hydraulic system drive water pressure be " raised in 50 psiincrements" until the

tod(s) were freed during single notch attempts, at which time the pressure "should

be immediately restored to the norrnal range" (260 270 psi). However, later in the

evolution during a subsequent observation, the inspectors noted that one control

rod appeared to withdraw from the core abnormally f ast, and determined that drive

water prewsure was still at an elevated level (approximately 400 psi), indicating that

drive pressure was not returned to the normal range following successfulinitial

movement. Additionally, operators did not return the drive water pressure to the

normal range prior to selecting and withdrawing the next rod in sequence. This

latter observation indicated that operators inappropriately remained M the stuch rod

procedure without first meeting the prerequisite of unsuccessful control rod

movement with normal drive water pressure. The inspectors questioned this

practice because it appeared to be contrary to the noted proceduro guldance, and

because continuous rod withdrawals from position 00 to 48 were being performed.

,

The senior reactor operator (SRO) supervising the evolution stated that he felt

justified in departing from the stuck rod procedure (both the prerequisites for usage

and step 4.6 regarding the incrementalincreases in drive pressure) in part because.

he was concerned that repeated cycling of the CRD pressure control valve was

distracting his reactor operator from monitoring the source range count rate nuclear

instrumentation. Further, the SRO stated that he " knew," based on experience, that

every rod in the test sequence would require an elevated drive water pressure in

order to be withdrawn. He further stated that the on duty operations

superintendent also endorsed this practice. The reactor engineering department

supervisor monitoring the evolution did not express a concern. The inspectors

shared their observations with a quality assurance inspector also present in the

control room but that individual did not independently pursue resolution of the issue

with station management. Finally, no narrative log entries were made describing

the basis for departing from the specific requirements of the abnormal operating

procedure.

The inspectors judged that operator's acted non-conservatively when they elected

not to adhere to the requirements of the stuck control rod abnormal operating

procedure, in that they permitted reactivity additions at potentially unknown or

uncontrolled rates. Specifically, operators performed an infrequent evolution which

added positive reactivity to an essentially now, untested reactor core with several

new control rod blades using CRD mechanisms and hydraulic control units which

had undergone either complete replacements or large scale maintenance, with their

operability not yet fully demonstrated. Defense-in-depth from a potential fission

product release was reduced since one of the principal barriers was degraded (i.e

the vessel head was removed). The one rod-out interlock was defeated because the

reactor mode switch was in "startup" to support performance of the test.

Moderator temperature was below 100 degrees F, increasing core reactivity. The

rod worth minimizer was inoperable and was being compensated by additional

human oversight Collectively, the inspectors judged that these conditions 6Sould

have warranted increased vigilance by reactor operators adding reactivity to the

core, especially during an evolution that is designed to verify that the reactor will

remain sufficiently ruberitical with twenty rods fully withdrawn.

The inspectors reviewed other PSE&G procedures prescribing expectations for

reactivity management and conservative decision making. The inspectors identified

two procedures, NC.NA AP.ZZ 0005(O) (NAP 5) and HC.0P AS.ZZ 0002(Z), which

provide guidance la these areas. Sections 5.21 and 6.30 of NAP-5 prescribe station .

'

policy on the use of reactivity controls and specifies that personnel "act

conservatively when f aced with adverse conditions which could affe-t reactor

safety." The latter noted procedure, which is a specific Hope Creek operations

department performance standard, requires operators to adhere to reactivity

manipulation procedures " alertly and cautiously," and to move control rods in a

" deliberate, :arefully controlled manner." The inspectors judged that the standards

of performance defined in these two documents were not met during the November

12,1997 shutdown margin demonstration.

Until the inspectors discussed their observations with senior site management on

November 13,1997, the significance of the noted issues went unrecognized by

station personnel. Station management demonstrated an appropriate response to

the issues, which included a formal debriefing with all of the station operators, and,

initiation of a formal root cause and fact finding investigation. Memorandums

reiterating expectations for maintaining " utmost caution" during reactivity

manipulations were also issued. The responsible on shif t operations superintendent

was reassigned to other duties.

The inspectors noted that no actual safety consequences resulted from performance

of the shutdown margin demonstration. Also, actual measured control rod speeds

during the test were later determined to be within the analyzed envelope. However,

plant eperation outside established reactivity manipulation procedures under the

described circumstances reflected a poor operating practice and was judged to be

an apparent violation of TS 6.8.1 procedure requirements. (eel 50 354/97 09 01)

c. Conclusions

Operators exhibited poor performance during the conduct of an infrequently

performed shutdown margin demonstration in that a stuck control rod procedure

was not followed and conservative decision making with regard to reactivity

management was not demonstrated. Additionally, these actions and decisions were

not sufficiently challenged by control room observers.

07 Quality Assurance in Operations

The Quality Assurance (QA) departrnent conducted a detailed team review and audit

of Hope Creek operations department performance with focus on technical

specification (TS) implementation and action tracking during the report period. The

inspectors observed portions of the audit and discussed relevant QA findings with

.

lead oversight personnel. The QA team concluded that verbal communications,

peer checking, infrequent evolution pre job briefs, and senior reactor operator

oversight of control room activities were good. No improper operability

determinations were identified. Howrver, the team Judged that procedure

placekeeping and documentation, as well as TS action statement tracking, were

weak. The team also concluded that there appeared to be a negative trend with

respect to conservative decision making. Several examples, including the above-

described shutdown margin demonstration issue, were used as a basis for reaching

this conclusion. The inspectors judged that QA findings were well supported,

independent, and promptly referred to station management for action.

08 Miscellaneous Operations issues

QL1 (Closed) LER 50 354/9713 01: unplanned high pressure toolant injection system

inoperability. This event was described in detailin NRC Inspection Report 50-

354/97 04 and resulted in issuance ci a violation of 10 CFR 50 Appendix B

Criterion XVI. This supplemental LER was submitted to describe in greater detail

the impact and significance of the event. Specifically, plant operators failed to enter

TS 3.0.3 and commence a plant shutdown because the inoperability of the high

pressure coolant injection (HPCI) system was not recognized during the period of

time when two trains of the residual heat removal system were inoperable for on-

line maintenance. The inspectors judged that the LER accurately described the

circumstances of the event and that proposed corrective actions were reasonable.

No additional new information was provided by this LER.

M1 Conduct of Maintenance

M 1.1 General Observations of Maintenance and Surveillanca

a. inspection Scope (71707)

Throughout the report period, the inspectors conducted frequent observations of

station maintenance and surveillance activities to verify proper procedures were in

use, adequate retests were completed or scheduled, monitoring and test equipment

(M&TE) was within calibration, housekeeping and foreign material exclusion

standards were satisfied, and coordination between departments was evident.

Additionally, the inspectors reviewed PSE&G actions taken in response to self-

identified or self revealing issues involving maintentnce or testing. A sample of

safety-related equipment tagouts were evaluated for adequacy of development and

implementation. Detailed assessments of specific observations and reviews are

described in section M4.

b. Observations and Findinas

,

The inspectors observed inconsistent performance with respect to maintenance

department activities. While most work orders reviewed spelfied adequate post-

maintenance retest activities, some were noted to be deficient because the

proposed tests were too narrowly focused. Though inspector verifications of

equipment tagouts did not identify any deficiencies, several self identified "near-

misses" were docurnented. Most observed maintenance was adequately supervised

and coordinated between engineeri ,g and operations, however on one instance

security grates were partially removed from circulating water system piping without

prior notification of security personnel to ensure that appropriate compensatory

measures were in place.

Weld overlay repairs of the through wallleak on the NSB core spray nozzle were

well planned, coordinated and executed. Underwater work in the primary

containment suppression pool to replace the *D" residual heat removal suction

strainer was aiso well executed. Torus cleaning activities were judged to be

excellent; the inspectors conducted an extensive pre closeout tour of the torus and

found only minor deficiencies.

Howover, several performance deficiencies were also noted. For example, foreign

~

.

material exclusion practices on the refuel floor were initially poor in that several

objects were inadvertently dropped into the reactor cavity while the reactor vessel

head was removed. Subsequent actions to improve performance in this area were

effective, including more strict use of lanyards, tool controls, etc. A vital bus loss

of power / loss of coolant accident surveillance test activity had to be repeated

because maintenance technicians improperly set up the M&TE used for test data

collection. Poor coordination with operations personnel during conduct of scram

discharge volume (SDV) flushing resulted in the generation of an unexpected half-

scum signal when water level exceeded SDV the trip setpoint.

,

c. Conclusions

Maintenance department technicians exhibited inconsistent performance during the

conduct of outage work activities and testing. While procedure and work order

usage was generally good, deficiencies in interdepartms. ital coordination and foreign

material exclusion controls were evident.

b. Observations and Findinas

Following a scheduled electronic governor replacement, maintenance technicians

began overspeed trip testing on the "B" EDG on September 27,1997. The

technicians noted during restoration from the %st that the mechanical governor

speed control adjustment, used during the o tspeed test, could not be returned to

its original pre test setting. The entire mechanical governor assembly was then

replaced based on a vendor recommendation, and the damaged unit was shipped

offsite to a repair f acility. PSE&G reviewed the maintenance history on the *D" EDG

mechanical governor and determined that the most likely failure of the speed control

was an over adjustment of the speed knob on September 27,1997 con blned with

inadequate tightening of internal governor dial stops in December 1994.

On September 29,1997, two attempts were made to start the "B" EDG for post-

maintenance testing af ter the mechanical governor replaccment. On both attempts

the EDG tripped on low lube ol' pressure. PSE&G later determined that the initial

setup of the new mechanical governor did not ellow the engine to develop sufficient

speed to clear the low lube oil pressure trip. PSE&G subsequently developed a new

procedure which provides guidance for performing initial diesel generator mechanical

governor setups af ter maintenance or replacement (" Diesel Generator Speed / Load

Control System Alignment," HC.MD CM.KJ-0015(O)h The inspectors learned that

previous mechanical governor maintenance was conducted with direct oversight by-

vendor representatives using work orders ind vendor technical references as

guidance.

On November 6,1997, following outage work, the "A" EDG was carrying the

10A401 vital bus in accordance with " Integrated Emergency Diesel Generator

1 AG400 Test 18 Months," HC.OP ST.KJ-0005(O). During the test, the control

room operators discovered that the EDG would not respond to speed changes. The

EDG was shut down and engineering personnel developed an action plan to

troublesnoot the control problem. Technicians subsequently determined that the

mechanical governor was improperly set, controlling the engine speed at too low a

value which prevented the electronic governor from effecting speed changes.

Further investigation by PSE&G determined that the speed knob on the mechanical

governor was not restored to the proper position at the conclusion of an earlier

overspeed test.

The inspectors noted that none of the affected EDG's described above were

required to be operable at the time of the maintenance or testing. Additionally, all

of the applicable technical specification EDG surveillance tests were completed

satisfactorily for each machine prior to restoring them to an operable status,

c. Conclusions

Namerous unplanned emergency diesel generator start attempts and equipment

restoration delays were encountered as a result of weak work controls over

mechanical governor maintenance and replacements.

M4.2 Reactor Core Isolation Coolina System Maintenance and lestina >

a, lasoection Scone (62707)

The inspectors reviewed the maintenance conducted prior to and following a reactor

'

core isolation cooling (RCIC) system turbine overspeed trip event du'ing testing,

b. Observations and Findinos

On November 9,1997, with the rtuctor plant in operational condWnn 6,

maintenance technich.ns attempted to perform an overspeed trip test of the RCIC

turbine using auxiliary steam in accordance with procedure HC.MD PM.FC 0001(O),

  • Reactor Core isolation and Cooling Steam Turbine Inspection and P.M." The pre.

Job brief for the evolution was good in that Individuals were assigned specific

4 actions should unforeseen e.ircumstances arise during the test. As required, the t

'

turbine was uncoupled from the pump and turbine speed was controlled from a local

potentiometer and was raised in 50 rpm increments, with an overspeed trip t

expected at approximately 5625 rpm. At 4900 rpm, the RCIC turbine unexpectedly  ;

accelerated to about 7500 rpm. A maintenance technician in the RCIC room

immediately tripped the turbine with the local trip device after recognizing the

,

overspeed condition, as assioned during the pre job brief. The RCIC system was

not required to be operable at the time of the test.

The inspectors judged the PSE&G's troubleshooting plans and follow up actions to

the overspeed event to be adequate. Based in part on vendor recommendations,

RCIC turbine inspections were conducted to verify that the no equipment damage

resulted. PSE&G determined that one of the causes of the event was that the

mechanical overspeed trip device was not properly set up during the previous

system maintenance, primarily bucause the work procedure did not provide

sufficient detail to ensure consistent implementation. PSE&G revised the HC.MD-

PM.FC 0001(Q) procedure to include a detailed verification that the mechanical

overspeed trip device is properly set prior to operating the turbine. Engineers

determined the most likely cause of the overspeed event, aside from the failure of '

the trip mechanism, was air entrapment in the turbine governor control oil following

a filter change. PSE&G enhanced the RCIC turbine operating procedures by adding

additional oil system venting activities to minimize the potential for air introductlen

during RCIC operation.

c. Conclusions

Maintenance technicians improperly set up the mechanical overspeed trip device for

'

the RCIC turbine in part due to weak procedural guidance, which complicated a

subsequent turbine overspeed event, insufficient venting of the turbine control oil

wystem, again partly because of limited procedure guidance, was judged to be the

primary cause of the overspeed event.

M8 Miscellaneous Maintenance issues

M8.1 (Closed) URI 50-354/97 07-02:"A" core spray nozzle (NSB) safe end laak, non-

destructive examination and repair.

a. htmgetion Scoce (73115)

This inspection was conducted as a followup to an issua 8M' unresolved following a

recent inservice inspection program assessment. The W ..ivolved the f ailure to

identify degradation prior to the development of a through wallloak in the NSB core

spray nozzle to safe end weld. The process employed to repair the lock (weld

overlay with .emperbead welding) on the low alloy steel nozzle was also reviewed.

b. Q32servations and Findinos

The inspectors reviewed PSE&G's formal root cause evaluation report for the NSB

core spray injection nozzle through-wallleak, dated November 4,1997, af ter

meeting with some of the participants on the evaluatio.: team. The inspectors

found ti at extensive fact gathering and root cause analysis were performed with

appropriate corrective actions either proposed or implemented. The safety

significance of the degraded NSB weld were discussed in the report, which stated

that there were no actual consequences and that there was no impact on public

health and safety. Though an increass in unidentified drywellleakage (from 0.3 to

0.0 gallons per minute) was noted in August 1997 during plant operation, this

increased leakage was withh TJ limits and was not associated with an increase in-

radiation. Because the crack exhibited the * leak before break" behavior expected

for the materials of construction, any further crack propagation with the plant

operating would have resulted in an increased unidentified leak rate followed by a

normal plant shutdown prior to a catastrophic pipe f ailure. Postulation of

consequences of the worst case event, that is a failure of the core spray line

initiated by a transient (e.g. seismic event) was evaluated by the PSE&G engineers

and found to be within the plant's design and licensing bases.

PSE&G identified one of the causal f actors of this issue was ineffective computer-

based ultrasonic testing (UT) dats evaluation. Recent re review of 1995 UT data

identified a misdiagnosed degrav'.d condition to have been present in 1995. The

1995 UT analyst noted the presence of a recordable indication, but judged that

there was no requirement for either supplemental non destructive examination (NDE)

or UT examination of the area containing the indication. PSE&G's recent review of

UT data on 19 other similar welds, including the conduct of UT on six of these

welds in 1997, did not identify any similar problems. On another set of 16 welds

that were examined by the somo UT process as the NSB weld, a reexamination of

six of these in 1997 by manual UT did not identify degradation. Other than the NSB

wold UT problem, no other incidents of a f ailure to identify potentially significant

flaws were found.

The 1995 UT analyr t dispositioned the NSB weld indication as acceptable based on

the nozzle weld data provided which indicated that the material was INCONEL 82

.

B

11

and was therefore not susceptible to stress corrosion cracking. During the

licensee's root cause analysis, it was determined that the construction material

should have been recorded as INCONEL 182 which is susceptible to cracking.

Immediate corrective actions to resolve the through-wallleakage included the repair

of the NSB weld by weld overlay. The corrective actions directed toward improving

the effectiveness of UT of welds similar to NSB included specific instructions to

Level 111 UT examiners for dissimilar welds, procedure reviews to clarify data

interpretation actions, industry involvement to improve UT of dissimilar welds,

additional review of causes and corrective actions, requirement for indepeMent

review of UT data by a second analyst for category D welds, consolidatice nd

review by data analysts of as-built data for each weld, and review of site specific

flaws and reflectors by the data analysts prior to review of new NDE data.

The failure to promptly idenufy the degraded core spray nozzle weld in 1995, a

condition adverse to quality, coupled with the f ailure to reques supplernental

nondestructive evaluation or supplemental ultrasonic examination of the area when

the indication was initially discovered, represented an inadequacy in the inservice

inspection program. As such, this event was deemed to be a violation of 10 CFR

50 Appendix B, Criterion XVI Corrective Action. However, because this violation

was non repetitive, and because of the prompt and thorough development of root

causes and corrective actions, thlF violation is being treated as a Non-Cited

Violatiore, consistent with Section Vll.B.1 of the NRC Enforcement Policy (NUREG-

1600). (NCV 50 345/97 09 02)

c. Conclusions

PSE&G performed a detailed and thorough evaluation of the failed core spray nozzle

weld history, previous nondestructive testing, and through wall leak causal f actors.

Proposed corrective actions were judged to be reasonable and appropriately focused

on preventing recurrence. However, the failure to detect and repair a weld flaw in

1995 during a focused ultrasonl< inspection of the noted core spray nozzle

highlighted weaknesses in th.: Hope Creek inservice inspection program.

M3.2 (Closed) LER 50 354/97 23: core spray nozzle weld through wallleak. This event is

described in dew in NRC Inspection Report 50-354/97 07 and was left unresolved

pending an NRC assessment of the completed root cause evaluation for why

analyses of a previot3.nna.t nic tes't of this nozzle failed to detect a weld flaw.

This assessment was wu sh I during the current report period with the results

described in section M8.1 above. No new information was provided by this LER.

filtration, recirculation, and ventilation system (FRVS) recirculation unit was found

to be inoperable just prior -o conducting a monthly technical specification (TS)

surveillance test on Sept inber 12,1997. PSE&G determined that the unit had

been inoperable since the conclusion of the previous monthly test completed on

.

.

12

August 17,1997, because of a recent surveillance tcat procedure change which

was deficient. Specifically, the FRVS test procedure was recently modified to

change the method used to verify heater power consumption at the end of a ten

hour heater run. However, no provision was included to allow the f an to run after

the heaters were deenergized to cool the coils. As such, when the unit ,is secured

following the August 17 test, the heater high-high temperature switch unsnowingly

tripped, rendering the unit inoperable. PSE&G recognized in t.'to LF.R discussion that

because the FRVS unit was inoperable for greater than sev',n days ithe TS allowed

outage time for one inoperable FRVS unit), the plant should have commenced a

shutdown on August 24,1997.

The inspectors verified that the FRVS surveillance test procedure was appropriately

revised following identification of this issue and that subsequsnt FRVS test runs

have not experienced any similar problems. This licensee-identified and corrected

technical specification violation is being treated as a Non-Cited Violation, consistent

with Section Vil of the NRC Enforcement Policy (NUREG 1600). (NCt! 50 354/97-

ELj. Jet Pumo Instrument Line Bracket Weld Crackina

a. Inspection Scope (37051)

The inspectors reviewed PSE&G's actions in response to a self identified discovery

of three jet pump sensing line bracket weld cracks,

b. Observations and Findinas

Oming in-vessel visual inspections of jet pumps, PSE&G inspectors determined that

rn pump numbers 8,9, and 15 all exhibited instrument line bracket weld cracks

v nich required repair. Station engineering personnel proposed the use of

" temporary" clamps to secure the affected sensing lines rather than repair the

deficient welds. Hope Creek staff also performed comprehensive inspections of all

20 jet pumps, including the lower elbows next to the inside of the vessel where

cracking had been recently discovered at the Peach Bottom Atomic Power Station

(GE-BWR4). No cracking was noted in these areas at Hope Creek.

A conference call between NRC and PSE&G technical staff was held on November

14,1997 to discuss the issues related to the proposed jet pump clamp repair

methodology. The clamp design was developed for use at the Susquehanna Steam

and Electric Station (GE-BWR4) where similar jet pump instrument line bracket weld

i

cracking was detected in 1994. The installed clamps had been inspected at that

station during two subsequent refueling outages with no noted degradation.

PSE&G performed a detailed analysis of the potential effects on reactor operation

should a jet pump instrument line break while at power, and concluded that there

would be no impact on safe plant operation. No concerns were raised during the .

course of the conference call.

The inspectors reviewad the design change package and associated evaluation for

installation of the jet pump clamps, and judged them to be acceptabla. Additionally,

thi inspectors observed portions of the actual clamp installation process, including a

review of the installation procedure, and did not identify 6ny deficiencies. Based on

the results of future refu(I outage inspections of these cumps, these jet pump

modifications may become a permanent installation.

c. Conclusiong

PSE&G promptly developed and implemented an acceptable design change pa::kage

,

to resolve a seliidentified issue involving bracket weld cracks on jet pump -

, instrument lines.

E2 Engineering Support of Facilities and Equipment

. Q1 Desian Chanae Packsae and Safetv Evaluation Review

a. Insoection Scoce (37551)

The inspectors reviewed the 10 CFR 50.59 safety evaluations associated with the

following plant system design modifications implemented during this report period:

  • lsofoam in the turbine auxiliaries cooling system (TACS) accumulator floating roof
  • Ultrasonic Test Scanner bearing cap - potentiallost part in reactor vessel
  • Alternate air supply to SACS flow control valve for safety-related chiller units

Additionally, the inspectors observed the installation of several other engineering

design change packages needed before the restart from the RF07 refuelinr, outage,

including:

  • Jet pump instrument line clamps
  • Rod sequence control system elimination

.

b. Observations and Findinas

PSE&G engineering developed approximately 70 design change packages for

installation during the RFO7 refueling outage, several of which were not part of the

original outage work scope but were deemed necessary as a result of self identified

adverse or degraded conditions. For instance, a safety evaluation was prepared on

November 12,1997, to assess the impact of plant operation with an unrecovered

loose part in the reactor vessel. Specifically, a 1" x 2" steel bearing cap which had

fallen ' ff an ultrasonic testing rig used for in-vessel weld inspections was never

recovered despite extensive efforts to locate and retrieve the item. The safety

evaluation thoroughly assessed the potential concerns associated with this lost part,

including possible effects on control rod movement, core flow restrictions, etc., and ,

judged that even though the issue involved a " change" to the facility as described ir,

the UFSAR,it did not result in the need for prior NRC review and approval.

Several other engineering saf sty evaluations were reviewed and judged to be

acceptable.10 CFR 50.59 " applicability reviews" and unreviewed safety question

determinations included sufficient scope, detail and analysis to justify tha final

conclusions. The inspectors determined that none of the plant modifications

reviewed resulted in final installed conditions which were inconsistent with.

continued safe plant operation. In fact, most of the 70 change evaluations

completed during the outage were developed to enhance safe and uneventful plant

operation, as opposed to simply accepting degraded conditions "as is" or providing

.

for operational conveniences. ,

Based on the limited sample of evaluations reviewed, the inspectors judged that the

quality of the 10 CFR 50.59 process had improved over the past operating cycle.

Process improvements such as evaluation " grading," cross disciplinary peer

roviewing, independent auditing, and focused engineering department training

resulted in better and more thorough safety evaluations. Based on interviews with

engineering management personnel, the inspectors learned that the process will

continue to evolve based on recently issued regulatory and industry guidanco,

c. Conclusions

Engineering department prepared safety evaluations were of good quality and were

appropriately focused on the potential nuclear safety impact of the r! ant design or

equipment changes.

E8 Miscellaneous Engineering issues

EQJ fClosed) LER 50-354/96-09: operation in an unanalyzed condition due to

inappropriate service water system / safety auxiliaries cooling system throttle valve-

settings. This LER describes a self-identified issue involving a March 1996

discovery that station service water (SSW) system throttle valves were set

improperly in November 1992 after a design change which replaced these valves,

that would have prevented adequate SSW cooling flow to the safety auxiliaries

cooling system (SACS) heat exchangers during design basis accident conditions.

PSE&G recognized that while no safety consequence resulted from this failure to

maintain appropriate system configuration control, the plant was operated for nearly

four years outside of the design and licensing basis (see NRC Inspection Report 50-

354/96 06). PSE&G attributed the cause of this deficiency to an inadequate

engineering design modification process, which in 1992 did not require design

calculation assumptions to be verified by field data collected after modification

installation.

- - _ .

.

.

15

The inspectors determined that PSE&G's design change process was modified to

include the need to conduct field verifications of design calculation assumptions.

Additionally, PSE&G conducted a thorough design bases validation of the SSW and

SACS systems by performing an independent service water system operational

performance inspection, an NRC review of which was documented in NRC

inspection Report 50-354/97-06. Lastly, in direct response to the issue described in

this LER, on October 23,1996, the NRC issued a violation of TS 3.7.1.2.b, which

requires that an operable service water flow path be maintained to ensure adequate

cooling to the SACS heat exchangers (see section E8.6 below).

kBJ (Closed) LER 50 354/9615: potential to operate in an unanalyzed condition due to

a design deficiency in the (service water emergency) overboard discharge line.

During station service water (SSW) system design bask reviews performed in

response to previously identified discrepancies, engineering personnel identified an

error in SSW design calculations in that emergency discharge point dynamic flow

conditions were not properly accounted for. This discovery rendered the technical

specification (TS) limit on maximum ultimate heat sink (UHS) temperature non-

conservatively high (see NRC inspection Reports 50 354/96 04,96 06, and 97-01).

A public meeting between the NRC and PSE&G was held on July 18,1996, to

discuss this and other related SSW and SACS system design issues, as well as

instituted compensatory measures and proposed corrective actions. Compensatory

measures included placement of an administrative limit on maximum UHS

temperature and development of specific operator actions in the event of a loss of

one SSW or SACS loop. Corrective actions included the conduct of an independent

service water system operational performance inspection, followed by the submittal

of any needed license change requests.

PSE&G completed its SSW/ SACS / UHS design basis review in May 1997, and

submitted associated TS amendment requests for NRC review promptly thereafter.

An independent NRC inspection of the design basis review effort was documented

in NRC Inspection Report 50 354/97-06. NRC review of PSE&G-proposed licenso

changes was completed in October 1997, and were issued as TS Amendment 106.

The NRC safety evaluation report included with this amendment did not identify any

concerns with the PSE&G-proposed changes.

EDJ (Closed) LER 50-354/97-24:as found values for safety relief valvo lift setpoints

exceed technical specification allowable limits. This LER was written to document a

repeat issue involving main steam line safety relief valve (SRV) setpoint drift outside

technical specification (TS) limits. As found " bench testing" of the 14 Hope Creek

SRV's, which are a two-stage Target Rock design, determined that ten of the valves

had excessive drift (worst case was + 9.4%). The setpoint drift issue has been an

on-going industry-wide concern and several industry-driven corrective actions have

been proposed. The inspectors determined that PSE&G has been aggressively

pursuing resolution of this issue, which has included design changes to SRV pilot

valve seating materials. All SRV setpoints wera verified to be within TS allowable

drif t limits prior to reinstallation in the main steam system.

.

16

EBA (Closed) LER 50 354/97 25: design deficiency potential for an unmonitored release

path through the station service water system. This LLR describes a self identified

discovery of a potential secondary containment bypass leakage pathway. After a

postulated loss of power accident, station service water (SSW) system solenoid-

operated vacuum breakers would fall open allowing the reactor building atmosphere

to communicate directly with SSW piping, which discharges water outside the

secondary containment. This design deficiency was recognized by technicians

performing maintenance on the noted sotenoids. PSE&G promptly developed a

design change packagt to re-route the vacuum breaker vent piping to the outside

environment rather than from inside the reactor building. The inspectors reviewed

the design change package and the associated safety evaluation, es well as walked

down the modified piping after installation was complete. No defic!sncies were

noted. The inspectors judged that PSE&G acted promptly and effectively in the

resolution of this issue.

,

ESJ (Closed) URI 50-354/96 04-06:non-conservative maximum ultimate heat sink

temperature limit. This issue was left unresolved pending NRC review of PSE&G

corrective actions to self identified discrepancies in the service water and safety

auxiliaries cooling system design bases. These discrepancies resulted in the need

for several compensatory measures to be put in place to ensure that the ncted

systems remained operable. A detailed discussion of the NRC and PSE&G follow up

to this and other related issues is described in sections E8.1 and E8.2 above.

EQJ (Closed) VIO 50-354/E96 281-04013: inappropriate service water / safety auxiliaries

cooling system throttle valve settings. This issue was described in detailin NRC

Inspection Report 50 354/96-06,LER 50-354/96-09,and section E8.1 above. The

inspectors verified that corrective actions stated in PSE&G's violation response

letter dated November 22,1996, were completed. These actions included (1) a

comprehensive service water system flow balance in which engineering flow

calculation assumptions were validated with field data, (2) the engineering process

for making design modifications was enhanced with additional specific training

provided, and (3) an independent service water system operational performance

inspection was conducted.

independent and diverse systems so that no single act can remove the capability of

detecting a threat and calling for assistance, or otherwise responding to the threat,

as required by NRC regulations,

b. Observations and Findinos

i inspector observations of CAS and SAS operations verified that the alarm stations

were equipped with the appropriate alarm, surveillance, and communication

capabilities. Interviews with CAS and SAS operators found them knowledgeable of

their duties and responsibilities. The inspectors also ver!fied through observations  ;

'

and interviews that the CAS and SAS operators were not required to engage in

activities that would interfere with the assessment and response functions, and that

.the licensee had exercised communication methods with the local law enforcement

agencies as committed in the Plan.

,

Additionally, on November 5,1997, the inspectors evaluated the effectiveness of

the assessnient aids, by observing on closed circuit television, a walkdown of the

4

protected area. The inspectors determined that the assessment aids in both cf the

alarm stations had adequate picture quality,

c. Conclusion

' The alarm stations and communications adequately implemented PSE&G's Plan

commitments and NRC requirements.

, a. Inspection Scope

The inspectors determined whether programs were implemented to ensure the

reliability of security related equipment, including proper installation, testing and

, maintsnance to replace defective or marginally effective equipment. Additionally,

the inspectors evaluated the effectiveness that the compensatory measures put in

place when security related equipment fails,

b. Observations and Findinas

Tht, inspectors reviewed testing and maintenance records for security related

equipment and found that documentation was on file to demonstrate that the

licensee was testing and maintaining systems and equipment as committed to in the

Plan. A priority status was being assigned to each work request and repairs were

normally completed the same day a work request necessitating compensatory

i measures was generated. The inspectors also noted that the working relationship

between security and maintenance departments was improving and tracking and

trending programs to monitor recurring equipment problems to determine when

,

engineering support was required, were being implemented.

found to be appropriate and minimal.

S5 Security and Safeguards Staff Training and Qualification

a. insoection Scone

The inspectors evaluated whether members of the security organization were

trained and qualified to perform each assigned security related job task or duty in

accordance with the NRC approved T&Q plan,

b. Observations and Findinas

On November 5,1997, the inspectors randomly selected and reviewed the T&Q

records of thirteen security force members (SFMs). Physical and firearms

requalification records were inspected for armed SFMs and security supervisors.

The inspectors found that the training had been conducted in accordance with the

T&Q Plan and was properly documented.

During discussions with the security training staff and security management, the  ;

inspectors were informed that new response weapons were purchased to enhance l

the licensee's tactical response capabilities. However, the new weapons will not be l

issued until all SFMs have been properly trained and qualified with the new

weapons. Further discussions revealed that the licensee was in the process of

upgrading its firing range. On November 6,1997, the inspectors toured the firing

range and determined, based on observations, that the upgrades would enhance

tactical response training. Additionally, the inspectors interviewed a number of

'

SFMs to determine if they possessed the requisite knowledge and ability to carry

out their assigned duties,

c. Conclusions

The inspectors determined that training had been conducted in accordance with the

T&Q plan. Based on the security force members responses to the inspectors *

questions and observations, the training provided by the security staff was

considered effective.

in@ection, which was conducted in April 1997. These enhancements included the

procurement and installation of four X ray machines for access search of packages,

and installation and implementation of hand geometry and range upgrades to

enhance tactical response training.

The inspectors reviewed the Manager - Nuclear Security's position in the

organizational structure and reporting chain. The Manager - Nuclear Security

reports to the General Manager Salem Operations, who reports directly to the

Senior Vice President - Nucleer Operations, who reports directly to the Chief Nuclear

Officer and President Nuclear Business Unit.

No problems with the organizational structure that could be detrimental to the

effective implementation of the security and safeguards programs were noted.

S7 Quality Assurance in Security and Safeguards Activities

S2d Audits

a. Insnection Sco.ag

The inspectors reviewed the licensee's Quality Assurance (QA) report of the NRC-

required security program audit to determine if the licensee's commitments as

contained in the Plan were being satisfied,

b. Observations and Findinas

The inspectors reviewed the 1997 combined QA audit of the security, access

authorization and fitness for-duty (FFD) programs, conducted May 19-30,1997,

(Audit No.97-031). The audit was found to have been conducted in accordance

with the Plan and FFD regulation. To enhance the effectiveness of the audit, the

PSE&G's QA audit team included four independent technical specialists.

The audit included findings in the security, access authorization and FFD areas,

however, the inspectors determined that the findings were not indicative of major

programmatic weaknesses. The inspectors further determined, based on

discussions with security management and FFD staff and a review of the responses

to the findings, that the resultant corrective actions were effective.

c. Conclusions

A recent Quality Assurance Audit of security was very comprehensive in scope and

depth, and at,dit findings were reported to the appropriate levels of management.

The inspectors judged that the audit program was being effectively administered.

88 Miscellaneous Security and Safeguards issues

Sfld Vehicle Barrier System (VBS)

General

On August 1,1994, the Commission amended 10 CFR Part 73, " Physical Protection

of Plants and Materials," to modify the design basis threat for radiological sabotage

to include the use of a land vehicle by adversaries for transporting personnel and

their hand carried equipment to the proximity of vital areas and to include the use of

,

a land vehicle bomb. The amendments required reactor licensees to install vehicle

control measures, including VBSs, to protect against the malevolent use of a land

vehicle. Regulatory Guide 5.68 and NUREC/CR-6190 were issued in August 1994

to provide guidance acceptable to the NRC by which the licensees could meet the

requirrments of the amended regulations.

Letters dated February 28,1996 and June 19,1996 from PSE&G to the NRC

forwarded Revisions 6 and 7 to its physical security plan that detailed the actions

implemented to meet the requirements of 10 CFR 73.55 (c)(7),(8), and (9) and the

design goals of the " Design Basis Land Vehicle" and " Design Basis Land Vehicle

Bomb." A NRC July 6,1996, letter advised the licensee that the changes

submitted had been reviewed and were determined to be consistent with the .

provisions of 10 CFR 50.54(p) and were acceptable for inclusion in the NRC-

approved security plan.

This inspection, conducted in accordance with NRC Inspection Manual Temporary

Instruction 2515/132," Malevolent Use of Vehicles at Nuclear Power Plants," dated

January 18,1996, assessed the implementation of the licensee's vehicle control

measures, including vehicle barrier systems, to determine if they were

commensurate with regulatory requirements and the licensee's physical security

plan.

The inspectors reviewed documentation that described the VBS and physically

inspected the as-built VBS to verify that it was consistent with the licensee's

summary description submitted to the NRC. The inspectors' walkdown of the VBS

and review of the VBS summary description disclosed that the as-built VBS was

consistent with the summary description and met or exceeded the specifications in

NUREG/CR-6190. The inspectors determined that there were no discrepancies in

the as-built VBS or the VBS summary description.

$12 Bomb Blast Analysis

The inspectors reviewed the licensee's documentation of the bomb blast analysis

and verified actual standoff distances provided by the as-built VBS. The inspectors'

review of the licensee's documentation of the bomb blast analysis determined that

it was consistent with the summary description submitted to the NRC. The

inspectors also verified that the actual standoff distances provided by their as-built

VBS were consistent with the minimum standoff distances calculated using

__ _ _.

'

NUREG/CR-6190. The standoff distances were verified by review of scaled-

drawings and actual field measurements. No discrepancies were noted in the

documentation of bomb blast analysis or actual standoff distances provided by the

as-built VBS.

, ESJ Procedural Controls

The inspectors reviewed applicable procedures to ensure that they had been revised

to include the VBS. The inspectors reviewed the licensee's procedures for VBS

access control measures, surveillance and compensatory measures. The procedures

contained effective controls to provide passage through the VBS, provide adequate

surveillance and inspection of the VBS, and provide adequate compensation for any

degradation of the VBS. The inspector's review of the procedures applicable to the

VBS disclosed no discrepancies.

V. Manaaement M_tafirnt

X1 Exit Meeting Summary

The inspectors presented their findings and conclusions to members of licensee

management at the conclusion of the report period on November 21,1997. The licensee

acknowledged the findings presented.

The inspectors asked the licensee whether any materials examined during the inspection

should be considered proprietary. No proprietary information was identified.

X2 Review of Updated Finst Safety Analysis Report (UFSAR)

A recent discovery of a licensee operating its f acility in a manner contrary to the UFSAR

description highlighted the need for a special focused review that compares plant practices,

procedures, and parameters to the UFSAR description. Since the UFSAR does not

specifically include security program requirements, the in:;pectors compared licensee

activities to the NRC approved physical security plan, which is the applicable document.

While performing the inspection discussed in this report, the inspectors reviewed

Section 4.1.2 of the Plan, titled " Protected Area - Physical Barrier Description" was

reviewed. The inspectors determined, by observations, that the protected erea barrier was

properly installed, maintained and satisfied the requirements of the Plan.
