  I. INTRODUCTION    '
    The Systematic Assess. tent of Licensee Performance (SALP) program is an
    integrated NRC staff effort to collect available observations and data on
    a periodic basis and to evaluate licensee performance based upon this
    information. SALP is supplemental to riormal regulatory processes used to
    ensure compliance to NRC rules and regulations. SALP is intended to be
    sufficiently diagnostic to provide a rational basis for allocating NRC
    resources and to provide meaningful guidance to the licensee's management
    to promote quality and safety of plant construction and operation.
    A NRC SALP Board, composed of s'taff meinbers listed below, met on
    September 4, 1986, to review the collect' ion of performance observations
    and data to assess the licensee's performance in accordance with the
    guidance in NRC Manual Chapter 0516, " Systematic Assessment of Licensee
    Performance." A summary of the guidance and evaluation criteria is
    provided in Section II of this report.

    II. CRITERIA
        Licensee performance is assessed in selected functional areas, depending
        upon whether the facility is in a construction, preoperational, or
        operating phase. Functional areas normally represent areas significant
        to nuclear safety and the environment. Some functional areas may not be
        assessed because of little or no licensee activities, or lack of meaningful
        observations. Special areas may be added to highlight significant
        observations.
        One or more of the following evaluation criteria were used to assess each
        functional area.
        1.  Management involvement and control in assuring quality
        2.  Approach to the resolution of technical issues from a safety
            standpoint
        3.  Responsiveness to NRC initiatives
        4.  Enforcement history
        5.  Operational and Construction events (including response to, analyses
            of, and corrective actions for)
        6.  Staffing (including management)
        However, the SALP Board is not limited to these criteria and others may
        have been used where appropriate.
        Based upon the SALP Board assessment each functional area evaluated is
        classified into one of three performance categories.    The definitions of
        these performance categories are:
                            ,
        Category 1: Reduced NRC attention may be appropriate. Licensee
        management attention and involvement are aggressive and oriented toward
        nuclear safety; licensee resources are ample and effectively used so that
        a high level of performance with respect to operational safety and
        construction quality is being achieved.
        Category 2:    NRC attention should be maintained at normal levels. Licensee
        management attention and involvement are evident and are concerned with
        nuclear safety; licensee resources are adequate and are reasonably
        effective so that satisfactory performance with respect to operational
        safety and construction quality is being achieved.
        Category 3: Both NRC and licensee attention should be increased. Licensee
        management attention and involvement is acceptable and considers nuclear
        safety, but weaknesses are evident; licensee resources appear to be strained
        or not effectively used so that minimally satisfactory performance with
        respect to operational safety or construction quality is being achieved.

          III. SUMMARY OF RESULTS
                The overall regulatory performance of the LACBWR Plant has continued at a
                satisfactory level during the assessment period. Performance in the area
                of Fire Protection declined from a Category 1 to a Category 2. Performance
                in the area of Maintenance / Modifications declined from a Category 2 to a
    -            Category 3 due to the high number of equipment failures which resulted in
                reactor scrams. Performance in the area of Outages is rated a Category 3
                this period due to the number of problems encountered during the 1986
                refueling outage.

    IV. PERFORMANCE ANALYSIS
        A.  Plant Operations
            1.    Analysis
                    Evaluation of this functional area was based on the results of
                    routine inspections conducted by region-based inspectors and the
                    resident inspector. In addition, this evaluation includes the
                    results of a special inspection that was conducted in response
                    to an unusual occurrence. The following violation was noted
                    during the evaluation period:
                          Severity Level IV - Inoperable low pressure coolant
                          injection system while the plant was pressurized
                          (409/85009).
                    The violation resulted from personnel error in that the Alternate
                    Core Spray (ACS) system was lined up to the river with manual
                    valves closed and tagged out during a hydrostatic test. This
                    happened because of insufficient communications during a shift
                    change. The hydrostatic test procedure required the ACS system
                    to be lined up for normal operation but this step was skipped in
                    the procedure. The procedure has been modified requiring all
                    steps to be initialed.    These closures would not have prevented
                    operation of the low press coolant injection system since the ACS
                    is supposed to pump river water directly into the vessel if
                    either of the normal water supplies was unavailable. Therefore,
                    from a safety standpoint the event was minor.
                    The special inspection was in response to an event on
                    October 23, 1985. Because this event was initially diagnosed as
                    a potential anticipated transient without scram (ATWS) event, the
                    licensee classified it as an alert and Region III dispatched a
                    special team to the site and also issued a Confirmatory Action
                    Letter (CAL). The event was an apparent failure to scram. A
                    scram alarm was received from the nuclear instrumentation (NI)
                    system without the expected scram. Normally, a scram should
                    occur coincident with a scram alarm; however, investigation by
                    the special team led to the conclusion that an actual scram high
                    flux level had not been reached and that there had not been a
                    failure of the reactor protection system. Ultimately, the
                    failure was found to be in the alarm circuit wherein (i) the
a                  alarm functioned prematurely, and (ii) that portion of the NI
                    system that actuates the alarm function was not synchronized with
                    its counterpart that actuates the scram function. It was further
                    concluded that, except for the alarm circuit, the reactor
                    protection system was functioning acceptably and that a scram
                    would have occurred had the appropriate level been reached.

      The direct involvement and cooperative attitude by LACBWR's
      management throughout this event was noteworthy. This involve-
      ment contributed to the resolution of the problem within 24
      hours, including the licensee's formal response to the CAL.
      Further, in response to an NRC request, the licensee devised
      a special test to verify the functional operability of the
      nuclear instrumentation system. As a result, all the technical
      issues associated with the event were resolved in a timely
      manner, with highest attention given to plant and personnel
      safety.
      The LACBWR facility experienced 17 RPS trips during this SALP
      period, resulting in a much higher trip rate than the industry
      average. Eight scrams were at power levels of 72% or higher.
      Ten of the 17 scrams were attributed to plant specific
      deficiencies which the licensee plans to remedy. For example,
i
      six of these scrams were attributed to marginal or obsolete
      equipment (i.e., four scrams were attributed to that portion of
      the NI system that uses a one-out-of-two scram logic, and two
      were caused by malfunctions of the 1A Static Inverter, an old
      inverter design that uses an electro-magnetic transfer switch
      rather than a solid-state transfer switch). In addition, four
      of the scrams were caused by either low gas pressure or low oil
      level indication on a single rod drive mechanism, Such scrams
    . are the result of the plant's initial design that results in a
      one-out-of-58 scram logic. It is significant to note that none
      of the scrams from power were due to licensed operator error.
      LACBWR's management is concerned about the frequency of the
      scrams being experienced and the challenges that scrams impose
      on plant safety and the shutdown system. LACBWR's management
      has analyzed the past scrams and has instituted a program
      directed toward reducing scrams.
      Toward this end, the licensee plans to replace the existing NI
      system with an improved NI system during the first half of 1987.
      The new NI system should reduce the number of scrams due to
      instrumentation spikes and to operator errors during plant
      startup and shutdown. The licensee had planned to replace the 1A
      Static Inverter with a larger unit having a solid state transfer
      switch during the 1987 refueling outage. However, the licensee
      took advantage of the required outage to repair the decay heat
      removal suction pipe and procured and installed the new inverter
      on August 29, 1986, subsequent to the expiration of this SALP
      period. This modification should improve the inverter's perform-
      ance and reduce scrams during transfer switch operation. Finally,
      the licensee is considering a modification that would eliminate
      partial scrams due to low gas pressure or oil level. In lieu of
      such partial scrams, the modification would cause an alarm to
      actuate upon low gas pressure or oil level indication on a single
      control rod drive mechanism, thereby eliminating the one-out-of-58
      scram logic. Such modification will, of course, be contingent
      upon NRC approval. Although these modifications may bode well
      for future SALP reports, they have not provided a positive impact
      for this SALP period.

      In addition to the 17 RPS trips previously mentioned, LACBWR
      experienced 24 other events during this SALP period which required
      the issuance of Licensee Event Reports (LERs). Eleven of these
      events occurred during the 12-month period of 1985, and thirteen
      occurred during the six-month period of 1986. Thus, the rate of
      reportable events for the most recent time period (the first six
      months of 1986) was more than twice that of the previous time
      period (all of 1985). Further, since the plant was down for
      refueling for about 72 days during the six-month period of 1986
      and for only 35 days during the 12-month period of 1985, the
      normalized rate for reportable events for comparable operating
      time is approximately three times greater for the 1986 time
      period than for the 1985 time period. Thus, not only have
      reactor scrams been unduly high during this SALP period, but the
      rate at which reportable events have occurred during the last six
      months of this SALP period has shown a marked increase. The
      repetitive nature of some of these reportable events is especially
      disconcerting. For example, the release of unsampled waste water
      with analyzed waste water occurred four times during this SALP
      period.
      The operations staffing is adequate, authorities and
      responsibilities are generally well defined and usually adhered              -
      to. Operations personnel are very experienced and knowledgeable
      of the plant and its characteristics and conduct themselves in a
      professional manner. Conduct in the control room is usually
  ~
      business like, professional and virtually without distractions.
      The operations staff moral is generally high and the attrition
      rate is extremely low. Operations procedures are adequate,
      well written, and generally adhered to. Plant management is
      involved in day-to-day activities and plant management personnel
      are often present in the plant and control room.
    2. Conclusion
      The licensee has performed well in this area as it relates
      to special and unexpected occurrences. Management's
      participation in responding to the presumed ATWS type event
      and its planning for future reduction of scrams is noteworthy.                -
      However, the operational problems experienced during this SALP
      period (e.g., the total number of reactor trips experienced,
      the increase in the rate of occurrence of reportable events
      and their repetitive nature), cause the overall rating for-
      this functional area to be Category 2.
    3. Board Recommendations
      The unusually high number of scrams and other reportable events
      experienced at LACBWR during this SALP period suggest that
      management should be more directly involved in the day-to-day
      operation of the facility.    Such involvement should be directed

              toward eliminating repetitive errors, providing clear-cut
              instructions regarding responsibilities of the various craft and
              operating personnel during the various plant operational modes to
              assure that the plant is maintained and operated in a safe manner
              and in conformance with the applicable regulations.
      B. Radiological Controls
        1.  Analysis
              Six inspections were performed during the assessnent period by
              region-based specialists. The inspections covered outage and
              operational radiation protection, liquid and gaseous radwaste,
              low-level radwaste shipments, and confirmatory measurements.
              Two violations were identified as follows:
              a.    Severity Level IV - Failure to monitor beta exposure rates
                    for workers in the reactor vessel (409/86003).
              b.    Severity Level IV - Failure to maintain radiation dose
                    records in accordance with Form NRC-5 requirements
                    (409/85015).
              The two violations, which appear to have resulted from lack of
              attention to details, represent improvement in this area over the
              six violations during the last assessment period. The licensee's
              corrective actions for both violations were appropriate and
              timely.
              The staffing level in this functional area during normal
              operational periods appears adequate. However, the staff
              appeared strained during the recent refueling and maintenance
              outage.  Radiation protection coverage of work in radiologically
              significant areas appeared only marginally adequate during that
              outage. The radiation protection staff normally is not supple-
              mented by contractors during outages. The only supplemental
              outage staffing is a part-time (one shift daily, five or six days
              a week) laundry operator. Routine labor intensive tasks such as
              laundry operation, waste packaging, and some custodial duties
              adversely impact on time available to provide radiological
*  -
              support for maintenance and operational activities during outages.
              The radiological control staff's experience level has improved
              since the past assessment period because of improved staff
              stability.
              Licensee responsiveness to NRC issues was generally acceptable
              with some improvement over the previous assessment period as
              evidenced by: the replacement of the liquid radwaste effluent
              monitor to improve sensitivity; replacement of aging internal
              proportional counters to improve quality of analytical measure-
              ments; the completion of quality related Regulatory Improvement
              Program Items; attention to specifics involved in evaluating and
              reporting environmental monitoring results; and revision of low

                  level radwaste shipment procedures to provide guidance to
                  determine radwaste classification in accordance with regulations.
                  However, these resolutions were not always completed in a timely
                  manner.
                  Management involvement in radiation protection and radwaste
                  matters was evident and generally adequate during the period.
                  Two liquid monitors were replaced with improved equipment,
                  backwashable filters were installed in the liquid waste effluent
                  line, and variability in the background of the environmental
                  detector which could affect environmental data was investigated.
                  Previously described problems concerning failure to ensure
                  adequate corrective actions for procedural violations, poor
                  coordination between radiatian protection personnel, and poor
                  utilization of the radiological incident report system were not
                  evident during this assessment ceriod. Management surveillance
                  of plant activities has also apprrently improved. However,
                  quality assurance review of routine radiation protection activi-
                  ties and records needs improvement as evidenced by inspection
                  findings concerning maintenance of dose records and film badge
                  spiking programs. Also, the individual who performed quality
                  assurance audits of radiation safety activities had limited
                  experience in the field. Several observations indicate a need
                  for improved attention to detail and/or supervisory review,
          ,
                  including contamination levels which were allowed to become
                  excessive before decontaminating the new liquid radwaste monitor;
                  procedural cross references were not always properly revised; and
                  during efficiency testing of a charcoal absorber filter when
                  iodine concentrations were too low to be detected, xenon was
                  substituted in the analysis which was inappropriate for assessing
                  iodine removal.
                  The licensee's approach to resolution of radiological technical
                  issues was good during the assessment period. The licensee
                  developed and implemented a formal respiratory protection
                  program and continued strengthening the station's contamination
                  control program, including termination of the permitted use of
                  laboratory coats for some contaminated area entries, continued
r                cleanup / reclamation of contaminated areas, strengthened frisker
,.                use requirements, and use of an improved personal contamination
l
                  monitor. Followup of a hydrogen explosion incident in the offgas
                  system was excellent.
                  Personal radiation exposures for 1985 (major portion of the
                  assessment period) were about 30% lower than the preceding year;
                  this is the third year of declining yearly exposure totals.              No
                  employee received in excess of five rems during 1985. To reduce
                  exposures (ALARA), the licensee added shielding in several
I
                  areas of containment, limits containment entries during power
j
                  operations, and provides improved ALARA review of specific tasks.

              Liquid radioactive releases have shown a gradual decline over
              the past several years (1.8 curies in 1985), but the licensee
              continues to release radioactive liquid wastes without treatment
              other than filtration.    During the assessment period four
              instances of failure to sample liquids prior to discharge were
              noted by the licensee. Three occasions involved operator and/or
    -
              procedure inadequacies, the fourth was an equipment failure.
              Gaseous radioactive releases in 1985 showed about a 20% reduction
              from 1984 releases. The reduction is primarily attributable to
              improved fuel cladding integrity. Solid waste volumes have been
              reduced mainly because of limiting materials permitted in
              contaminated areas. There were no transportation incidents.
              The licensee has improved his QA/QC program for analytical
              measurements on counting data by using control charts and
              malfunction sheets to describe problems and corrective actions
              for each instrument. Chloride analyses continue to be a problem
              although effort was expended in an attempt to solve the problem.
              The licensee's results in the confirmatory measurements program
              remain essentially unchanged with one disagreement for the
              comparisons made with the NRC.
        2.  Conclusion
              The licensee is rated Category 2, which is the same rating
              achieved in the previous SALP period; however, performance was
              improved over the previous SALP period.
        3.  Board Recommendations

      C. Maintenance / Modifications
i        1.  Analysis
              Inspections of maintenance / modification activities were conducted
              by the resident inspector and region-based inspectors to verify
              that these activities were performed in accordance with Technical
,            Specification and quality assurance requirements. No violations
l            or deviations were noted in these areas.
,
              Three distinct type of maintenance activities were reviewed:
              (1) corrective maintenance activities requiring the interruption
              of plant operations, (i.e., maintenance activities resulting in
              forced outages wherein the plant was either shutdown or power
              reduced);    (2) corrective maintenance activities not requiring
              the interruption of plant operations, per se, but which impose
              a Limiting Condition of Operation (LCO) on continued plant
              operation; and (3) preventive maintenance (PM) activities. The
              licensee performed 18 corrective maintenance actions which
                                        10

    .
    -
        required the interruption of plant operations and several
        corrective maintenance actions which placed the plant in a LC0
        during this SALP period.
        On occasions the corrective maintenance actions taken by the
        licensee appeared to have been directed toward the symptom rather
        than the cause. For example, five malfunctions occurred during
        this SALP period (i.e., on 7/10/85, 9/9/85, 11/15/85, 11/18/85
        and 12/14/85) that caused the 1A forced circulation pump's
        discharge valve to close. The closing of the valve, in turn,
        caused a reduction of reactor power until the valve was reopened.
        Absent a systematic failure analysis, these malfunctions had,
        at various times, been attributed to spikes in a " delta T"
        subtractor circuit used to compare the temperature in both forced
        circulation loops and to erratic output from a worn out potentio-
        meter in the same circuit. Ultimately, during a plant shutdown
        on January 8, 1986, while trouble shooting the circuits that
        control the pump's discharge valve, a defective solenoid was
        found and replaced. Since the valve has not malfunctioned
        subsequent to replacing the defective solenoid, it appears that
        the root cause for the malfunctions has been determined.
        A similar diagnostic deficiency appears to have involved a
        malfunction that did not cause a power reduction but placed the
        plant in a LCO. On July 1, 1985, while operating at about 98%
      -
        power, the 1A Diesel Driven High Pressure Service Water Pump
        failed its monthly surveillance test, (i.e., the diesel started
        but stopped almost immediately thereafter). This failure placed
        the plant in an LC0 requiring the reactor to be in a hot shutdown
        mode within 12 hours and in a cold shutdown mode within the next
        30 hours unless the pump was made operable in less than 12 hours.
        Subsequent to the diesel's initial failure, additional tests were
        conducted and additional diesel stop failures were experienced.
        Finally, after approximately eight hours after the initial
        failure, the pump passed its surveillance test and about an hour
        later the diesel was again started successfully. Based on the
,        apparent successful tests, the licensee declared the pump
        operable.
'
        Because of the failures experienced subsequent to the initial
        diesel failure, coupled with the fact that the actual cause had
        not been determined and corrective maintenance, per se, was not
i        conducted, the licensee planned for additional troubleshooting
  .      and initiated a monitoring program requiring that the priming
        tank level be monitored daily. In addition, because of the
        uncertainties involving the diesel's performance, the licensee
        conducted surveillance tests on July 9, 10, 11 and 12, 1985.
        Several diesel stop failures occurred while conducting these
        tests.    Following each failure, maintenance actions were
        performed and a successful surveillance test conducted, after
        which the unit was again deemed to be operable. During this time
        period, the licensee identified several potential causes for the

                          failures, but the root cause was not discovered until July 12,
                          1985. At that time an Allis Chalmers representative discovered a
                          sluggish valve in the fuel supply line that had been overlooked
                          during previous troubleshooting. This valve was overlooked
                          because maintenance history records indicated that it was
                          installed on the 1B HPSW diesel and not in the 1A diesel and the
                          fact that this particular valve has the appearance of a line
                          fitting rather than that of a valve.                  Upon cleaning this valve
                          the diesel starting problems were apparently solved (e.g., the
                          diesel was successfully started on July 13, 14, 15, 17, and 19
                          with no intervening failures).
                          Eighty-one modifications (facility changes) were completed during
                          this SALP evaluation period. Most of the modifications were
                          directed toward improving plant operations. However, several
                          modifications were directed toward enhancing plant safety by
                          responding to recommendations by the licensee's Safety Review and
                          Operating Review Committees. Examples of facility changes that
                          should enhance plant safety are highlighted below:
                          a.    The elastomeric components of the upper control rod drive
                                mechanical seals were upgraded. This change should improve
                                plant reliability and safety because the seals are more
                                resistant to fluctuations in operating temperatures. This
                                change has not been implemented on all control rod drive
                                mechanisms; however, the new material has been placed in
                                stock, and will be used on the remaining units when routine
                                maintenance is performed.
                          b.    A turbocharger was added to the 1A High Pressure Service
                                Water Diesel Engine. This modification was aimed at improv-
                                ing the diesel engine's reliability and at increasing its
                                rating, thereby assuring ample service water flow.
                          c.    Reactor wide range water level transmitter 50-42-305 was
                                replaced with a new unit having a local rather than a remote
                                amplifier. The new equipment is qualified to withstand the
                                postulated harsh environment and is judged to be superior to
                                the original equipment.
                          d.    The electronics of the component cooling water and turbine
                                condenser liquid radiation monitors were upgraded to provide
                                more sensitive and reliable radiation monitoring.
                          Staffing in the maintenance area is adequate.                          Personnel are
                          experienced and knowledgeable.                Authorities and responsibilities
                          are well defined. Maintenance personnel have received training
                          on plant systems and overall plant operations. This training
                          contributes to their understanding of the effect of their activi-
                          ties on the plant operation. Maintenance procedures are generally
                          adequate and adhered to.                Management involvement is good at both
                          the site and corporate levels, as evidenced by the many plant

                                                                attitude.
                                                                The age of many components at LACBWR and the fact that the
;
                                                                nuclear' steam system suppler (Allis-Chalmers) is no longer a
                                                              ' viable source for replacement of parts that are wearing out,
                                                                suggests that the licensee should upgrade and implement a more
F'                                                              extensive and systematic preventive maintenance program. 'This
                                                                program should include a systems engineering evaluation for the

                                                                17 RPS Trips which occurred during this evaluation period, 13
.
                                                                were caused by mechanical equipment problems (6 at power levels >
                                                                72% and 7 at power levels < 1%). This strongly' suggests the need
l                                                                for improvement in the preventive and corrective maintenance
4                                                                areas.      It is recognized that many actions were initiated during
                                                                this evaluation period to reduce the number of such problems, but
                                                                the effectiveness of these actions was not current during this
,
                                                                appraisal period. The major constraint associated with such a PM
                                                                program is, of course, the potential negative impact of ALARA
'
1                                                                considerations. Accordingly, the PM program should, to the
                                                                maximum degree practicable, use mock-ups prior to undertaking
,                                                                complex maintenance activities.
'
                                                        2.      Conclusion
                                                                The licensee's performance regarding maintenance, especially as
                                                                it relates to failure analysis, and the effectiveness of the
,
                                                                preventive maintenance program appears to have declined from that
l                                                                of the previous SALP evaluation and should be given additional
                                                                attention by the licensee. On the other hand the licensee's
,
                                                                modification program is~ considered very effective in not only
                                                                improving operations but also in enhancing safety. However, due
                                                                to the large number of equipment failures which have resulted in
                                                                reactor scrams and other reportable events the overall performance

                                                                  on a spot-check basis that surveillance tests were performed as
                                                                  required.' The region-based inspectors performed in-depth inspec-
                                                                  tions of the licensee's-program for inservice testing of pumps
                                                                  and valves, and of.startup core performance testing. .None of
                                                                  these inspections resulted in violations or deviations.
                                                                  The surveillance activities inspected were performed in a very
                                                                  professional manner and found to be well managed. No surveillances
                                                                  were missed during the period. For example, the. manner by which
                                                                  surveillance activities are conducted clearly indicate that the
                                                                  authorities and responsibilities in this area are clearly defined,
                                                                  personnel involved in this area are very knowledgeable and
                                                                  proficient in performing their assigned tasks, and prior planning
                                                                  has been well developed. The licensee's training program in this
                                                                  area stresses the need for adherence to procedures, thereby
                                                                  assuring that the surveillance actions do not compromise plant

                                                                  be complete, well maintained and readily available. Likewise,
                                                                  the licensee's audit reports were found to be complete and
                                                                  thorough.
                                                                  The licensee has implemented an inservice testing program and was
                                                                  conducting testing in accordance with the requirements of the
                                                                  ASME Code.    Modifications or revisions to the inservice testing

                                                                  The licensee responded to technical issues in a timely manner
                                                                  with appropriate justifications and supportive documentation.
                                                                  The licensee was in the process of assigning acceptable
                                                                  instrument accuracy values to plant instruments for which no

    E. Fire Protection
      1.  Analysis              -
            The resident inspector performed routine inspections in this area
            during this evaluation period, including evaluation of potential
            fire hazards, plant housekeeping and cleanliness and compliance
            with LACBWR's fire protection plan. The inspections indicated
            excellent housekeeping practices, indicating a marked improvement
            from that of a previous inspection. One special inspection was
            performed by region based inspectors and their consultants during
            this evaluation period to verify the adequacy of the facility's
            post fire safe shutdown method (Section III.G., J, 0, and L of
            Appendix R), and other fire protection features and modifications.
            One violation was identified:
                  Severity Level V - Failure to hydrostatically test fire
                  extinguishers (409/85013).
            Concerns were raised during the special inspection regarding:
            *    The sprinkler system, fire detectors and the partial height
                  fire wall between the fire pumps in the cribhouse did not
                  provide reasonable assurance (as described in the Supplemen-
                  tal Safety Evaluation Report, dated March 23,1983) that at
                  least one fire pump would remain functional, should a
                  disabling fire occur in the cribhouse. The licensee has
                  acknowledged this concern and corrective actions are
                  expected in this area. Some corrective actions in this area
                  have been taken by the licensee.  For example, the licensee
                  has relocated the starting battery for the 1B high pressure
                  service water pump, which is also a fire pump, to satisfy
                  the Appendix R commitment. This relocation resolved the
                  concern associated with the height of the fire wall between
                  the fire pumps.
            *    The inspectors observed that no area wide fire detection
                  system existed in the control room as specified by Section
                  5.7.4 of the SER; however, the license condition related to
                                    15
 
  .-
  *
                            the completion of facility modifications to improve the fire
                            protection program did not include installation of an area
                            wide fire detection system in the control room. The licensee
                            committed to installing an area wide fire detection system
                            in the control room at the exit meeting of July 11, 1985.
    -          *          Adequate control of combustibles was observed by the
                            inspectors, although special mention was made regarding the
                            storage of combustible materials in the electric equipment
                            room and implied throughout the plant. The inspectors
                            indicated that combustible materials not essential for
                            routine operation should be removed.        Improvement in this
                            area is desirable.
                Also reviewed during this inspection was the fire brigade
                composition and training portion of the licensee's fire protec-
                tion program. The fire brigade composition and training
                conformed to the guidelines of Appendix A to Branch Technical
                Position 9.5-1, although four brigade training program
                implementation weaknesses were identified. One additional
                concern noted regarded the current licensee's policy on normally
                designating the Shift Supervisor as the fire brigade leader.
                This practice is discouraged by Appendix A. The licensee was
                encouraged to reconsider the use of the Shift Supervisor as the
                fire brigade leader.
      .
                Management involvement and support of their staff during the
                inspection was appropriate to the circumstances and the licensee
                was willing to listen and discuss inspector raised concerns.
                Observations by the resident inspector of site conditions
                generally indicated excellent housekeeping practices. Problem
                areas identified were promptly corrected and do not appear to
                be repetitive. Management and staff appear to take a positive
                attitude towards housekeeping and fire prevention.
            2.  Conclusion
                The licensee is rated Category 2 in this area with continued
;                strength in the area of housekeeping.
            3.  Board Recommendations
                None.

      F.  Emergency Preparedness
            1.  Analysis
                Two inspections were conducted during the SALP period, one
                  routine inspection and one exercise. The routine inspection was
                conducted in April 1985 and resulted in the closing of 14 open

  .
  *
      items and the opening of five more. However, the five new items
      were of a minor nature and did not involve any violations.      Two
      of the open items dealt with inconsistencies between the newly
      revised Emergency Preparedness Plan and the Emergency Plan
      Procedures. Two more items related to emergency equipment which
      was satisfactory but not adequately described in the Plan, in one
      case, and in the other case required upgrading based on ALARA
      concerns.    The fifth open item referred to the hiring of an
      additional person, part of whose functions would have been to
      assist the Emergency Planning Coordinator.
      This latter personnel need has been resolved by replacing the
      previous Emergency Planning Coordinator with a more qualified
      individual who has an SR0 license. The licensee believes that
      the appointment of a more qualified Coordinator eliminates the
      need for an assistant.
      The licensee's annual exercise was conducted in June 1985 and
      resulted in two weaknesses regarding the notifications to State
      and local agencies. The initial notification for the Site Area
      Emergency was completed within 27 minutes rather than the
      required 15 minutes and the notifications did not always specify
      whether a release was taking place, as specified by the licensee's
      Emergency Plan.
      Management control, measured by the number of violations and open
    '
      items, has improved since the SALP-5 period but still has room
      for further improvement. For example, in the May 1984 routine
      inspection, nine inspection-related open items were closed, but
      seven new items were opened, four of them being violations. Thus,
      the April 1985 routine inspection, mentioned above, was an
      improvement since 14 Open Items were closed and only five items
      (none of them being violations) were opened. However, the open
      item concerning inventories that was found in April 1985, was
      never corrected during the SALP-6 period and led to a subsequent
      violation in 1986.
      During the last two to three years there has been a noticeable
      improvement in the licensee's responsiveness to NRC concerns.
      There are no long-standing regulatory issues attributable to
      the licensee. The licensee is generally timely in its responses
      but there are still exceptions to this.      For example, the June 25,
      1985 exercise resulted in a weakness in their notification
-
      performance after declaration of an emergency.      Less than 30 days
      later during a real event (loss of Offsite power) the licensee
      failed to notify the State of Minnesota within the required 15
      minutes.    Timely corrective action on the exercise weakness would
      have prevented the notification problem identified during the
      actual event.
      The enforcement history is improving. In the previous SALP
      period there were five violations, whereas there were none
      during this SALP period.
                              17
 
  .
                  ' Staffing at the management level has been unchanged, and the
                    selection of an experienced SR0 for the Emergency Planning
                    Coordinator position should be an improvement in staffing.
                    Training and qualification effectiveness is generally good as
                    demonstrated by the elimination of any violations during the
                    SALP period.      However, documentation and record keeping of
                    training must be further improved. The methodology the licensee
                    used to track completed training resulted in three operators
                    missing their annual emergency preparedness training by up to
                    three months.
              2.  Conclusion
                    The licensee is rated Category 2 in this area. The licensee
                    was rated a Category 2 in the last SALP period.
              3.  Board Recommendations
                    None.
    G.        Security
              1.  Analysis
    -
                    Two security inspections were conducted by region-based physical
                    security inspectors during the assessment period. Both were
                    routine inspections. Additionally, the Resident Inspector
                    routinely conducted observations of security activities. Five
                    violations were identified relative to the security program as
                    follows:
                    a.    Severity Level IV - A security screen was inadequately
                          fastened to a vital area structure (409/85016).
                    b.    Severity Level IV - Search hardware failed to perform as
                          required (409/85016).
                    c.    Severity Level IV - Some alarm zones failed to perform as
i
                          required (409/85016),
                    d.    Severity Level IV - Failure to implement adequate
                          compensatory measures (409/86004).
                    e.    Severity Level V - Failure to maintain a clear isolation
                          zone (409/85016).
                    Allegations were received by Region III that dealt with security
                    at the facility involving compensatory measures not being
l
                    implemented, alarms not being recognized; events not being

        reported to the NRC; and vital area doors left open. The alleged
        events occurred in 1982 and did not involve current deficiencies.
        They could not be fully substantiated. No violations were cited
        as a result of any of the allegations.
        Weaknesses identified by NRC inspectors were noted that did not
        involve violations in the areas of assessment aids, protected
        area physical barriers, security system maintenance, and
        . discrepancies between the security plan and the contingency
        plan. When the violations and weaknesses were identified, the
        licensee usually took corrective action in a timely and
        effective manner.
        Some weaknesses and violations were not self-identified.
        Although they were not major in nature, they were recognizable
        and could have been corrected, had they been identified. Since
        there was an increase in cited violations from the previous SALP,
        the licensee should consider a closer and more thorough management
        review of the system to identify potential problem areas and
        correct them before they become more significant.
        Positions within the security organization are identified and
        responsibilities are well defined. In November 1985, a new
        Security Director was hired to replace the former Security
        Director who was promoted to the corporate office. The new
      -
        security director has established and maintained good
        communications with Region III safeguards staff.
        Events reported under 10 CFR 73.71 were properly identified and
        analyzed. There were six reported events which dealt with
        computer problems, such as loss of primary power and protected
        area alarm malfunction. Records are generally complete, well
        maintained, and available.
        Review of the security training program and its effectiveness
        was limited. Those portions of the training records reviewed
        were adequate.    No major problems in performance were noted
        which indicated significant weaknesses in training.
                                                                            *
        There were no technical issues involving physical security from
        a safety standpoint which required resolution during this
        assessment period.
        Management's support for the security program has continued and
        was made evident by the purchasing of a walkthrough metal
        detector, hand-held explosives detectors, CCTV cameras, hand-held
          radios, and upgrading the backup security power supply.
          In summary, management's support for the program has increased.
        The effectiveness of that support may be increased through a
        more aggressive program for self-identification of potential
        problems and reviews to determine cost effective protective

  .
  .          improvements to the program. This has been shown in the
              upgrading of some security equipment. The number of violations
              and weaknesses have increased since the previous SALP period;
              however, they were of a minor significance.
        2.  Conclusion
              The licensee is rated Category 2 in this area, which is the same
              rating achieved in the last assessment period. However, the
              overall licensee performance is declining.

      H. Outages
        1.  Analysis
              Evaluation of this functional area was based on the results
              of inspections conducted by the resident inspector involving
              the scheduled 1986 refueling outage, an inspection by a
              region-based inspector regarding the review of selected
              procedures and equipment checkouts associated with the 1986
              refueling outage, and a special inspection by region-based
              inspectors in response to potential damage to the core spray
              bundle during the refueling outage. The inspections included
              observations of maintenance, refueling, and post-maintenance
              conducted during the outage and the review of selected
              administrative and procedural requirements. No violations
              of deviations were noted for this area.
              The licensee completed its 1985 and 1986 refueling outages during
              this SALP period. However, because there was no resident
              inspector on site during the 1985 refueling outage, it is not
              discussed in this report.    The 1986 refueling outage was
              initially scheduled to be accomplished in approximately 42 days;
              however, because of several problems experienced during the
              outage, the actual refueling duration was 70 days.
*
              The inspection activities performed by the region-based inspector
              included a review of fuel handling equipment checkout and fuel
    ~
              transfer procedures, surveillance test procedures and operating
              manuals, observation of fuel handling activities, verification of
              performance of fuel transfer accountability records and review of
              surveillance test results. The findings associated with this
              inspection indicated that (i) licensee performance was properly
              managed and effective, (ii) fuel movement activities were conduc-
              ted in strict adherence to approved procedures and without error,
              and (iii) procedures used during the refueling outage were
              technically adequate and properly approved.
              As previously indicated, the licensee experienced several problems
              during the 1986 refueling outage that increased its duration by
                                      20

  '
            about 30 days. Some of the problems were due to personnel error
            and others to equipment malfunctions. The more significant of
            these events and their impact on the outage are highlighted in
            the paragraphs that follow.
            On March 7, 1986, one day prior to the scheduled refueling outage,
            the reactor scrammed when a 2400 volt reserve feed breaker failed
            to close while transferring plant loads from the main source to
            the reserve source. Although the actual increase in outage time
            accrued to this event is unknown, it adversely impacted the
            refueling outage by diverting electrical maintenance personnel
            from scheduled PM activities to corrective maintenance activities
            on the breaker, thereby placing an additional unplanned work load
            on the staff during a hectic period.
            On March 12, 1986, while the upper cavity was being flooded,
            water leaked from a thermocouple conduit that penetrates the
            shield wall into containment. This event was due to personnel
            error and poor communications between maintenance and operating
            staff personnel. (i.e., A wrong sized thermocouple plug was
            installed in the penetration conduit; however, this fact was not
            clearly communicated to the operating staff. Thus, the cavity
            was being filled while a leak path existed from the cavity to
            containment). This event delayed the outage by about one day and
        ,
            also created a contamination control problem inside containment.
            On March 15, 1986, while control rod handling was in progress,
            the control rod in position 19 was found to be unlatched from its
            drive mechanism. The control rod drive mechanism for this rod
            had been last installed in September of 1984; therefore, it was
            reasonably assumed that the rod had been unlatched since that
            date. Upon finding the unlatched rod, a test program was insti-
            tuted to verify that all the other rods were latched. Although
            this event was not complicated, i.e., the reinstallation of ''
            unlatched rod was straightforward, as was the testing to ensu
            that all rods were latched, it added about three days to the
            refueling outage.
            On April 3, 1986, while lowering the high pressure core spray
            (HPCS) bundle into the reactor vessel, the bundle struck the
            vessel's internals on at least two occasions. On April 4, while
            attempting to bolt down the bundle it did not seat properly and
            was sitting about one-half inch higher than it should. The
            bundle was, therefore, removed fron the vessel and returned to
            the fuel element storage well and inspected. The inspection
            revealed that the four outermost tubes of the bundle had been
            bent inwards about 20 to 35 degrees. Because of the concern
            regarding damage to a safety system, a special inspection was
            conducted by region-based inspectors. Based on their review of
            this event, the inspectors concluded that the corrective
            actions taken were acceptable and that no safety concerns or
            violations existed. (NOTE: The actual reason for the seating

      problem was not determined until August, while the plant was
      shutdown to repair a pipe leak. While removing fuel, the
      licensee found a bent handle on one of the fuel assemblies.
      Subsequent examinations and review of video tapes revealed that

      the 1986 refueling outage. Thus, the fuel assembly's
      protruding handling obstructed the initial seating of the HPCS
      bundle).    Several factors contributed to this event, including
      the constraints associated with working in a high radiation
      area, poor visibility, poor crane alignment markings, and
      perhaps undue pressure. These factors ultimately led to what
      can be euphemistically called personnel error. This incident
      adversely impacted the refueling outage by adding about ten
      days to the outage.
      In addition to the incidents highlighted above, several other
      events occurred during the 1986 refueling outage. The cumulative
      effect of these events was to increase the outage duration about
      five days. Said events include the dropping of an underwater
      light shield and clamp into the reactor; the breaking of the
      source connecting bolts while the source was being moved from the
      storage well to the reactor such that the lower third of the
      source (the plug end) landed in the reactor; the damaging
      (twisting) of the upper band of a new fuel assembly while it was
      being lifted from its storage position; and a small fire that was
      quickly controlled in the lagging of the 18 forced circulation
      pump's discharge piping.
      Although the licensee does not have the same size staff as many
      other licensees, it does have knowledgeable and experienced
      staff member from each plant discipline who routinely work
      together to provide the planning and scheduling function for
      the plant. This approach has worked well over the years. In
      addition, the licensee has experienced good control over outage
      work packages.    This is partially due to the fact that most of
      the outage work is done by licensee personnel, with very little
      work being performed by contractors. However, when contractor
      personnel are utilized, adequate communication and supervision
      is provided to assure control over their work activities.
      Some of the problems experienced during the 1986 refueling
      outage could have been prevented by more diligent attention
      to detail by both maintenance and operating personnel.
      Likewise, improved communications between maintenance and
      operating management personnel could have improved the overall
      performance during the 1986 refueling outage.
    2. Conclusion
      The licensee is rated Category 3 in this area.

      3.  Board Recommendations
            Because of the number of reportable events (10) experienced ~during
            the 1986 refueling outage and the repetitive nature of some of
            the events, it is recommended that LACBWR management be more
            directly involved in the-day-to-day activities during refueling
            outages.    Said involvement should be aimed at assuring that the
            refueling activities are performed properly, that appropriate
            administrative controls are implemented and that clear lines of
            communications are maintained between maintenance staff and
            operating staff.
    I. Quality Programs and Administrative Controls Affecting Quality
      1.  Analysis
            Evaluation of this functional area was based on the results of
            routine inspections conducted at the Lacrosse Boiling Water
            Reactor (LACBWR) by the resident inspector and two inspections by
            region-based inspectors. The inspections for this area included
            routine inspections regarding administrative controls for
            maintenance and operations and deviation reports with respect to
            the Quality Assurance Plan and the role of the Quality Assurance
            Staff.    No violations or deviations in this area were noted.
    *
            The first region-based inspection for this area was conducted in
            the beginning of the SALP period and was aimed at evaluating this
            functional area as it relates to (i) the Offsite Review Committee,
            (ii) the Offsite Support Staff, and (iii) the Nonroutine Reporting
            Program.    The licensee was essentially in a transition status
            during this early part of the SALP period, e.g., actions had been
            initiated or planned in those areas which would result in minor
            changes in the licensee's commitment or in its performance to
            requirements. These actions and their results were not expected
            to have any major safety significance.
            The second region-based inspection for this area was aimed at
            evaluating LACBWR's maintenance, QA/QC administration, tests and
            experiments, receipt, storage and handling, and procurement. The
            inspector verified that the licensee had implemented a written
            program relative to maintenance activities and QA/QC administra-
            tion that was in conformance with Technical Specifications,
            regulatory requirements, commitments and industry guides or
>
            standards.
            The licensee's quality programs and administrative control
            affecting quality gave evidence of prior planning, assignment of
            priorities, and decision making that was usually at a level to
            ensure adequate management review.    The responsiveness to NRC
            initiatives was timely with acceptable resolution to concerns.
            Events were usually identified and reported in an accurate and
            timely manner.

  -              The licensee's policies in the areas inspected are adequately
                  stated and understood, and the procedures are adequately defined
                  and stated for the control of those activities.        Audits have been
                  complete and thorough.          Corporate management was usually involved
                  in site activities, and management attention and involvement are
                  evident and show concern for nuclear safety. Quality program
                  activities appear to be controlled adequately. The implementation
                  of the QA program is acceptable as reflected in overall plant
                performance.
        2.      Conclusion
                  The licensee is rated Category 2 in this area.

    J.  Licensing Activities
        1.      Analysis
                  a.    Methodology
                        The basis of this appraisal was the licensee's performance
                        in support of licensing actions that were either completed
                        or active during the current rating period.        These actions,
                        consisting of license amendment requests, exemption requests,
                        relief requests, responses or generic letters, TMI items,

          During the SALP period, 61 licensing actions were            .
          completed which consisted of 45 plant-specific actions,
          10 multi plant actions, and six TMI (NUREG-0737) actions.
          A very important licensing activity completed during the
          review period was the issuance'of a primary property
          damage insurance exemption for LACBWR.    This achievement
          is noteworthy because LACBWR is the first utility to
          provide adequate technical justification to support such
          an exemption at the Commission level.
          In addition, the project manager and other members of the
          NRR staff participated in reviews at the plant concerning
          the post accident sampling system, systematic evaluation
          program topics as well as an Appendix R fire protection
          audit.

  *
        b. Management Involvement and Control in Assuring Quality
          During this rating period, the licensee has demonstrated a
          very active role in licensing-related activities.    Strong
          management involvement has beea especially evident where
          issues have potential for substantial safety impact and
          extended shutdowns.    Licensee management actively partici-
          pated in an effort to work closely with the NRC staff and
          management to promote a good working relationship.    The
          majority of submittals were consistently clear and of high
          quality.    The licensee management frequently participated
          in meetings in Bethesda on short notice.
          There is one area which indicates a lack of management
          attention, and that is the setting of priorities of
          licensing actions to be evaluated by the NRC staff.
          During the winter 1986 refueling outage management at the
          site informed the NRC staff the top priority licensing
          action were those related to restart and at the same time
          the Lacrosse headquarters management informed the NRC
          staff that the property damage insurance exemption was the
          highest priority licensing action.    This conflict almost
          resulted in the licensee having to request an emergency
          technical specification change to allow startup. This
          conflict and other communication problems between the staff
      -
          and the licensee were brought to the attention of the
          licensee's management. The licensee's management has worked
          out the internal problems and worked closely with the NRC
          staff in the last three months of the evaluation period to
          correct these problems. We recognize a strong improving
          trend.
        c. Approach to Resolution of Technical Issues from a
          Safety Standpoint
          The licensee almost always demonstrated a strong
          understanding of the technical issues involved in licensing
          actions and proposed technically sound, thorough, and timely
          resolution. However, there have been issues where the
          licensee's approach was good, but the licensee did not
.  .      thoroughly understand NRR staff guidance. Once the staff
          guidance was fully explained, the licensee proposed timely
          solutions which were technically sound and exhibited proper
          conservatism. For a few issues, full explanation of the
          staff guidance required an above average amount of staff
          effort.    Examples of such issues are post accident sampling
          system, ECCS technical specifications and purge and vent.
        d. Responsiveness to NRC Initiatives
          The licensee has been responsive to NRC initiatives. During
            the rating period, it made every effort to meet or exceed
                                26
 
                                                                                                I
.
'
            commitments.  Responsiveness by the licensee facilitated
            timely completion of staff review of a large number of
            licensing actions and thus substantially reduced the
            licensing backlog. The licensee's quality of license
            amendment requests, especially the "no significant hazards
            consideration" improved significantly after the " counter-
            parts" meeting held on January 30, 1986 in Bethesda, where
            this topic was discussed in detail. The licensee has
            responded promptly and accurately to various surveys
            conducted during the reporting period.
            In addition, the licensee at the staff's request has
            provided submittals for the staff in a very short turn-
            around time. This was especially evident in the licensee's
            response to the staff's request for the LACBWR status on
            the implementation of generic requirements. The licensee
            was required to review a vast amount of documentation and
            provided the NRC staff with a timely response which was of
            high quality,
      e.    Staffing
            The licensee has maintained adequate licensing staff to
            assure timely response to the NRC needs.
      During this period, the licensee's performance was found to be
      above average to excellent overall. Management attention and
      involvement was generally as expected. This was evident in both
      the safe and efficient operation of the facility. Staffing
      levels and quality were adequate. Communication levels between
      the operating staff and proper management were established and
      generally effective. The licensee has been, in most cases,
      effective in dealing with significant problems and NRC initiatives.
      The licensee's attention to housekeeping appears to have been
      excellent. The licensee's efforts in the functional area of
      Licensing Activities has significantly improved during this
      evaluation period. This is reflected in the quality of work,
      attention to NRR concerns and involvement of senior management.
      DPC was an active participant at the counterparts meeting of
      January 30, 1986, in Bethesda, Maryland.
    2. Conclusion
      The overall rating for the functional area of licensing
      activities is Category 1.
    3. Board Recommendations
      None.

  K. Training and Qualification Effectiveness
    1.  Analysis
          A training effectiveness inspection conducted during the
          assessment period identified no generic training-related problems.
          The training feedback of lessons learned from plant events was
          accomplished primarily in supervisor meetings and by required
          reading which appeared adequate. However, licensed operators did
          express a desire for more input on general plant problems. The
          training programs for non-licensed personnel were primarily based
          on on-the-job training (0JT) with minimal classroom instruction.
          The requalification training for licensed operations consisted of
          required lectures conducted on a 24-month cycle and simulated
          manipulations. Initial qualification training consisted of
          attendance at the requalification lectures and 0JT.    The success
          rate for initial licensing examinations in the past has been
          consistent with national averages over the last several years.
          However, during this evaluation period the success rate declined
          to less than the national average when only seven of the eleven
          candidates passed their examinations.
          It was determined by the inspection and operator licensing
          staffs that the Lacrosse operator license training program did
          not provide the three months of on-shift training for senior
          reactor operator candidates for the specific purpose of preparing
          them for Shift Supervisor duties. It was also determined that
          the applications submitted by two reactor operator candidates
          contained inaccurate information and that certain training
          credited to them was not relevant to their license training.
          It was also determined that training deficiencies existed for
          previous senior reactor operator candidates.
          These issues were discussed at two meetings held on May 7 and
          May 30, 1986, in the Region III office with management represen-  -
          tatives from Dairyland Power Cooperative and the NRC. During
          the May 30 meeting the licensee agreed to implement a documented
          on-shift training program for senior reactor operators and to
          provide this training to currently licensed senior reactor
          operators identified in a letter dated June 5, 1986, from
          Mr. James W. Taylor, General Manager, Lacrosse.
          Based upon the examination results during the assessment period
          and the implementation of the on-shift training program for
          senior reactor operators, the Lacrosse license training program
          is considered satisfactory.
          A separate evaluation of radiological controls training indicated
          that the licensee is developing a formal health physics technician
          training / retraining program. Training is performed mainly by
          station professionals and by required self-study. The training
          has contributed to an adequate understanding of work and fair
          adherence to procedures with a modest number of personnel errors.

      V. SUPPORTING DATA AND SUMARIES
        A.  Licensee Activities
            The unit engaged in routine power operation throughout most of
            SALP 6 except for two major scheduled outages for plant refueling,
            modification, and maintenance. The first one began on March 10,
            1985 and was completed on April 17, 1985. The next refueling outage

      C. Investigations and Allegations Review
        A contractor employee had concerns related to the fact that
        compensatory measures were not taken for out-of-service alarms and
        vital area doors were left open without a security guard present.
        The alleged events occurred in 1982 and could not be substantiated.

      In the SALP 5 period, the licensee issued 32 LERs in 18 months
      for ar, issue rate of 1.8 per month.      In the SALP 6 period the
      licensee issued 39 LERs in 18 months for an issue rate of 2.2
      per month. By comparison to like plants (to which there are
      few) the number of LERs is high.
      Sixteen of the LERs were related to scrams, four were due to
      unsampled water being discharged, three due to the high pressure
      service water diesel, two for degraded fire barriers, seven for
    -
      ESF actuations, two due to leakage test failures, one was because
      the HPCS bundle was b?nt, one due to an unlatched control rod,
      one due to a cracked valve, one due to a wrong alternate core
      spray lineup, and one because of an apparent failure to scram.
      Three events reported under 10 CFR 50.72 requirements were
      considered significant and were discussed at the Operating
      Reactor Events Briefing (OREB) in Headquarters. The first
      related to a loss of offsite power and a scram that occurred on
      October 22, 1985. This event was classified an unusual event.
      This event occurred due to maintenance personnel error when the
      plant was at 98% power.      The scram was normal without complica-
      tions and the emergency diesel generator started ano powered all
      required loads normally. The event was promptly reported within
      16 minutes of its occurrence, and within an hour, offsite power
      was restored and the unusual event terminated. The second event
      occurred on October 23, 1985 and related to an apparent failure
      to scram upon receipt of a high flux signal. The failure to
      scram was caused by electrical failure that caused a malfunction
      of the reactor protection system (RPS). the control rods were
      manually inserted to bring the reactor subcritical. The plant
      was placed under alert conditions for a brief period, and all
      concerned agencies were notified promptly. The third event
      discussed at the OREB occurred on March 6, 1986 and related to
      the ignition of the turbine offgas stream during sampling
      activities.

I. INTRODUCTION '

The Systematic Assess. tent of Licensee Performance (SALP) program is an

integrated NRC staff effort to collect available observations and data on

a periodic basis and to evaluate licensee performance based upon this

information. SALP is supplemental to riormal regulatory processes used to

ensure compliance to NRC rules and regulations. SALP is intended to be

sufficiently diagnostic to provide a rational basis for allocating NRC

resources and to provide meaningful guidance to the licensee's management

to promote quality and safety of plant construction and operation.

A NRC SALP Board, composed of s'taff meinbers listed below, met on

September 4, 1986, to review the collect' ion of performance observations

and data to assess the licensee's performance in accordance with the

guidance in NRC Manual Chapter 0516, " Systematic Assessment of Licensee

Performance." A summary of the guidance and evaluation criteria is

provided in Section II of this report.

II. CRITERIA

Licensee performance is assessed in selected functional areas, depending

upon whether the facility is in a construction, preoperational, or

operating phase. Functional areas normally represent areas significant

to nuclear safety and the environment. Some functional areas may not be

assessed because of little or no licensee activities, or lack of meaningful

observations. Special areas may be added to highlight significant

observations.

One or more of the following evaluation criteria were used to assess each

functional area.

1. Management involvement and control in assuring quality

2. Approach to the resolution of technical issues from a safety

standpoint

3. Responsiveness to NRC initiatives

4. Enforcement history

5. Operational and Construction events (including response to, analyses

of, and corrective actions for)

6. Staffing (including management)

However, the SALP Board is not limited to these criteria and others may

have been used where appropriate.

Based upon the SALP Board assessment each functional area evaluated is

classified into one of three performance categories. The definitions of

these performance categories are:

,

Category 1: Reduced NRC attention may be appropriate. Licensee

management attention and involvement are aggressive and oriented toward

nuclear safety; licensee resources are ample and effectively used so that

a high level of performance with respect to operational safety and

construction quality is being achieved.

Category 2: NRC attention should be maintained at normal levels. Licensee

management attention and involvement are evident and are concerned with

nuclear safety; licensee resources are adequate and are reasonably

effective so that satisfactory performance with respect to operational

safety and construction quality is being achieved.

Category 3: Both NRC and licensee attention should be increased. Licensee

management attention and involvement is acceptable and considers nuclear

safety, but weaknesses are evident; licensee resources appear to be strained

or not effectively used so that minimally satisfactory performance with

respect to operational safety or construction quality is being achieved.

III. SUMMARY OF RESULTS

The overall regulatory performance of the LACBWR Plant has continued at a

satisfactory level during the assessment period. Performance in the area

of Fire Protection declined from a Category 1 to a Category 2. Performance

in the area of Maintenance / Modifications declined from a Category 2 to a

- Category 3 due to the high number of equipment failures which resulted in

reactor scrams. Performance in the area of Outages is rated a Category 3

this period due to the number of problems encountered during the 1986

refueling outage.

IV. PERFORMANCE ANALYSIS

A. Plant Operations

1. Analysis

Evaluation of this functional area was based on the results of

routine inspections conducted by region-based inspectors and the

resident inspector. In addition, this evaluation includes the

results of a special inspection that was conducted in response

to an unusual occurrence. The following violation was noted

during the evaluation period:

Severity Level IV - Inoperable low pressure coolant

injection system while the plant was pressurized

(409/85009).

The violation resulted from personnel error in that the Alternate

Core Spray (ACS) system was lined up to the river with manual

valves closed and tagged out during a hydrostatic test. This

happened because of insufficient communications during a shift

change. The hydrostatic test procedure required the ACS system

to be lined up for normal operation but this step was skipped in

the procedure. The procedure has been modified requiring all

steps to be initialed. These closures would not have prevented

operation of the low press coolant injection system since the ACS

is supposed to pump river water directly into the vessel if

either of the normal water supplies was unavailable. Therefore,

from a safety standpoint the event was minor.

The special inspection was in response to an event on

October 23, 1985. Because this event was initially diagnosed as

a potential anticipated transient without scram (ATWS) event, the

licensee classified it as an alert and Region III dispatched a

special team to the site and also issued a Confirmatory Action

Letter (CAL). The event was an apparent failure to scram. A

scram alarm was received from the nuclear instrumentation (NI)

system without the expected scram. Normally, a scram should

occur coincident with a scram alarm; however, investigation by

the special team led to the conclusion that an actual scram high

flux level had not been reached and that there had not been a

failure of the reactor protection system. Ultimately, the

failure was found to be in the alarm circuit wherein (i) the

a alarm functioned prematurely, and (ii) that portion of the NI

system that actuates the alarm function was not synchronized with

its counterpart that actuates the scram function. It was further

concluded that, except for the alarm circuit, the reactor

protection system was functioning acceptably and that a scram

would have occurred had the appropriate level been reached.

The direct involvement and cooperative attitude by LACBWR's

management throughout this event was noteworthy. This involve-

ment contributed to the resolution of the problem within 24

hours, including the licensee's formal response to the CAL.

Further, in response to an NRC request, the licensee devised

a special test to verify the functional operability of the

nuclear instrumentation system. As a result, all the technical

issues associated with the event were resolved in a timely

manner, with highest attention given to plant and personnel

safety.

The LACBWR facility experienced 17 RPS trips during this SALP

period, resulting in a much higher trip rate than the industry

average. Eight scrams were at power levels of 72% or higher.

Ten of the 17 scrams were attributed to plant specific

deficiencies which the licensee plans to remedy. For example,

i

six of these scrams were attributed to marginal or obsolete

equipment (i.e., four scrams were attributed to that portion of

the NI system that uses a one-out-of-two scram logic, and two

were caused by malfunctions of the 1A Static Inverter, an old

inverter design that uses an electro-magnetic transfer switch

rather than a solid-state transfer switch). In addition, four

of the scrams were caused by either low gas pressure or low oil

level indication on a single rod drive mechanism, Such scrams

. are the result of the plant's initial design that results in a

one-out-of-58 scram logic. It is significant to note that none

of the scrams from power were due to licensed operator error.

LACBWR's management is concerned about the frequency of the

scrams being experienced and the challenges that scrams impose

on plant safety and the shutdown system. LACBWR's management

has analyzed the past scrams and has instituted a program

directed toward reducing scrams.

Toward this end, the licensee plans to replace the existing NI

system with an improved NI system during the first half of 1987.

The new NI system should reduce the number of scrams due to

instrumentation spikes and to operator errors during plant

startup and shutdown. The licensee had planned to replace the 1A

Static Inverter with a larger unit having a solid state transfer

switch during the 1987 refueling outage. However, the licensee

took advantage of the required outage to repair the decay heat

removal suction pipe and procured and installed the new inverter

on August 29, 1986, subsequent to the expiration of this SALP

period. This modification should improve the inverter's perform-

ance and reduce scrams during transfer switch operation. Finally,

the licensee is considering a modification that would eliminate

partial scrams due to low gas pressure or oil level. In lieu of

such partial scrams, the modification would cause an alarm to

actuate upon low gas pressure or oil level indication on a single

control rod drive mechanism, thereby eliminating the one-out-of-58

scram logic. Such modification will, of course, be contingent

upon NRC approval. Although these modifications may bode well

for future SALP reports, they have not provided a positive impact

for this SALP period.

.

In addition to the 17 RPS trips previously mentioned, LACBWR

experienced 24 other events during this SALP period which required

the issuance of Licensee Event Reports (LERs). Eleven of these

events occurred during the 12-month period of 1985, and thirteen

occurred during the six-month period of 1986. Thus, the rate of

reportable events for the most recent time period (the first six

months of 1986) was more than twice that of the previous time

period (all of 1985). Further, since the plant was down for

refueling for about 72 days during the six-month period of 1986

and for only 35 days during the 12-month period of 1985, the

normalized rate for reportable events for comparable operating

time is approximately three times greater for the 1986 time

period than for the 1985 time period. Thus, not only have

reactor scrams been unduly high during this SALP period, but the

rate at which reportable events have occurred during the last six

months of this SALP period has shown a marked increase. The

repetitive nature of some of these reportable events is especially

disconcerting. For example, the release of unsampled waste water

with analyzed waste water occurred four times during this SALP

period.

The operations staffing is adequate, authorities and

responsibilities are generally well defined and usually adhered -

to. Operations personnel are very experienced and knowledgeable

of the plant and its characteristics and conduct themselves in a

professional manner. Conduct in the control room is usually

~

business like, professional and virtually without distractions.

The operations staff moral is generally high and the attrition

rate is extremely low. Operations procedures are adequate,

well written, and generally adhered to. Plant management is

involved in day-to-day activities and plant management personnel

are often present in the plant and control room.

2. Conclusion

The licensee has performed well in this area as it relates

to special and unexpected occurrences. Management's

participation in responding to the presumed ATWS type event

and its planning for future reduction of scrams is noteworthy. -

However, the operational problems experienced during this SALP

period (e.g., the total number of reactor trips experienced,

the increase in the rate of occurrence of reportable events

and their repetitive nature), cause the overall rating for-

this functional area to be Category 2.

3. Board Recommendations

The unusually high number of scrams and other reportable events

experienced at LACBWR during this SALP period suggest that

management should be more directly involved in the day-to-day

toward eliminating repetitive errors, providing clear-cut

instructions regarding responsibilities of the various craft and

operating personnel during the various plant operational modes to

assure that the plant is maintained and operated in a safe manner

and in conformance with the applicable regulations.

B. Radiological Controls

1. Analysis

Six inspections were performed during the assessnent period by

region-based specialists. The inspections covered outage and

operational radiation protection, liquid and gaseous radwaste,

low-level radwaste shipments, and confirmatory measurements.

Two violations were identified as follows:

a. Severity Level IV - Failure to monitor beta exposure rates

for workers in the reactor vessel (409/86003).

b. Severity Level IV - Failure to maintain radiation dose

records in accordance with Form NRC-5 requirements

(409/85015).

The two violations, which appear to have resulted from lack of

attention to details, represent improvement in this area over the

six violations during the last assessment period. The licensee's

corrective actions for both violations were appropriate and

timely.

The staffing level in this functional area during normal

operational periods appears adequate. However, the staff

appeared strained during the recent refueling and maintenance

outage. Radiation protection coverage of work in radiologically

significant areas appeared only marginally adequate during that

outage. The radiation protection staff normally is not supple-

mented by contractors during outages. The only supplemental

outage staffing is a part-time (one shift daily, five or six days

a week) laundry operator. Routine labor intensive tasks such as

laundry operation, waste packaging, and some custodial duties

adversely impact on time available to provide radiological

  • -

support for maintenance and operational activities during outages.

The radiological control staff's experience level has improved

since the past assessment period because of improved staff

stability.

Licensee responsiveness to NRC issues was generally acceptable

with some improvement over the previous assessment period as

evidenced by: the replacement of the liquid radwaste effluent

monitor to improve sensitivity; replacement of aging internal

proportional counters to improve quality of analytical measure-

ments; the completion of quality related Regulatory Improvement

Program Items; attention to specifics involved in evaluating and

reporting environmental monitoring results; and revision of low

.

'

level radwaste shipment procedures to provide guidance to

determine radwaste classification in accordance with regulations.

However, these resolutions were not always completed in a timely

manner.

Management involvement in radiation protection and radwaste

matters was evident and generally adequate during the period.

Two liquid monitors were replaced with improved equipment,

backwashable filters were installed in the liquid waste effluent

line, and variability in the background of the environmental

detector which could affect environmental data was investigated.

Previously described problems concerning failure to ensure

adequate corrective actions for procedural violations, poor

coordination between radiatian protection personnel, and poor

utilization of the radiological incident report system were not

evident during this assessment ceriod. Management surveillance

of plant activities has also apprrently improved. However,

quality assurance review of routine radiation protection activi-

ties and records needs improvement as evidenced by inspection

findings concerning maintenance of dose records and film badge

spiking programs. Also, the individual who performed quality

assurance audits of radiation safety activities had limited

experience in the field. Several observations indicate a need

for improved attention to detail and/or supervisory review,

,

including contamination levels which were allowed to become

excessive before decontaminating the new liquid radwaste monitor;

procedural cross references were not always properly revised; and

during efficiency testing of a charcoal absorber filter when

iodine concentrations were too low to be detected, xenon was

substituted in the analysis which was inappropriate for assessing

iodine removal.

The licensee's approach to resolution of radiological technical

issues was good during the assessment period. The licensee

developed and implemented a formal respiratory protection

program and continued strengthening the station's contamination

control program, including termination of the permitted use of

laboratory coats for some contaminated area entries, continued

r cleanup / reclamation of contaminated areas, strengthened frisker

,. use requirements, and use of an improved personal contamination

l

monitor. Followup of a hydrogen explosion incident in the offgas

system was excellent.

Personal radiation exposures for 1985 (major portion of the

assessment period) were about 30% lower than the preceding year;

this is the third year of declining yearly exposure totals. No

employee received in excess of five rems during 1985. To reduce

exposures (ALARA), the licensee added shielding in several

I

areas of containment, limits containment entries during power

j

operations, and provides improved ALARA review of specific tasks.

.

Liquid radioactive releases have shown a gradual decline over

the past several years (1.8 curies in 1985), but the licensee

continues to release radioactive liquid wastes without treatment

other than filtration. During the assessment period four

instances of failure to sample liquids prior to discharge were

noted by the licensee. Three occasions involved operator and/or

-

procedure inadequacies, the fourth was an equipment failure.

Gaseous radioactive releases in 1985 showed about a 20% reduction

from 1984 releases. The reduction is primarily attributable to

improved fuel cladding integrity. Solid waste volumes have been

reduced mainly because of limiting materials permitted in

contaminated areas. There were no transportation incidents.

The licensee has improved his QA/QC program for analytical

measurements on counting data by using control charts and

malfunction sheets to describe problems and corrective actions

for each instrument. Chloride analyses continue to be a problem

although effort was expended in an attempt to solve the problem.

The licensee's results in the confirmatory measurements program

remain essentially unchanged with one disagreement for the

comparisons made with the NRC.

2. Conclusion

The licensee is rated Category 2, which is the same rating

achieved in the previous SALP period; however, performance was

improved over the previous SALP period.

3. Board Recommendations

None.

C. Maintenance / Modifications

i 1. Analysis

Inspections of maintenance / modification activities were conducted

by the resident inspector and region-based inspectors to verify

that these activities were performed in accordance with Technical

, Specification and quality assurance requirements. No violations

l or deviations were noted in these areas.

,

Three distinct type of maintenance activities were reviewed:

(1) corrective maintenance activities requiring the interruption

of plant operations, (i.e., maintenance activities resulting in

forced outages wherein the plant was either shutdown or power

reduced); (2) corrective maintenance activities not requiring

the interruption of plant operations, per se, but which impose

a Limiting Condition of Operation (LCO) on continued plant

operation; and (3) preventive maintenance (PM) activities. The

licensee performed 18 corrective maintenance actions which

10

!

,

__ __ _ ._.

- _ _ __ _. -_-

--

.

-

required the interruption of plant operations and several

corrective maintenance actions which placed the plant in a LC0

during this SALP period.

On occasions the corrective maintenance actions taken by the

licensee appeared to have been directed toward the symptom rather

than the cause. For example, five malfunctions occurred during

this SALP period (i.e., on 7/10/85, 9/9/85, 11/15/85, 11/18/85

and 12/14/85) that caused the 1A forced circulation pump's

discharge valve to close. The closing of the valve, in turn,

caused a reduction of reactor power until the valve was reopened.

Absent a systematic failure analysis, these malfunctions had,

at various times, been attributed to spikes in a " delta T"

subtractor circuit used to compare the temperature in both forced

circulation loops and to erratic output from a worn out potentio-

meter in the same circuit. Ultimately, during a plant shutdown

on January 8, 1986, while trouble shooting the circuits that

control the pump's discharge valve, a defective solenoid was

found and replaced. Since the valve has not malfunctioned

subsequent to replacing the defective solenoid, it appears that

the root cause for the malfunctions has been determined.

A similar diagnostic deficiency appears to have involved a

malfunction that did not cause a power reduction but placed the

plant in a LCO. On July 1, 1985, while operating at about 98%

-

power, the 1A Diesel Driven High Pressure Service Water Pump

failed its monthly surveillance test, (i.e., the diesel started

but stopped almost immediately thereafter). This failure placed

the plant in an LC0 requiring the reactor to be in a hot shutdown

mode within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in a cold shutdown mode within the next

30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> unless the pump was made operable in less than 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Subsequent to the diesel's initial failure, additional tests were

conducted and additional diesel stop failures were experienced.

Finally, after approximately eight hours after the initial

failure, the pump passed its surveillance test and about an hour

later the diesel was again started successfully. Based on the

, apparent successful tests, the licensee declared the pump

operable.

'

Because of the failures experienced subsequent to the initial

diesel failure, coupled with the fact that the actual cause had

not been determined and corrective maintenance, per se, was not

i conducted, the licensee planned for additional troubleshooting

. and initiated a monitoring program requiring that the priming

tank level be monitored daily. In addition, because of the

uncertainties involving the diesel's performance, the licensee

conducted surveillance tests on July 9, 10, 11 and 12, 1985.

Several diesel stop failures occurred while conducting these

tests. Following each failure, maintenance actions were

performed and a successful surveillance test conducted, after

which the unit was again deemed to be operable. During this time

period, the licensee identified several potential causes for the

t

I

.

~

failures, but the root cause was not discovered until July 12,

1985. At that time an Allis Chalmers representative discovered a

sluggish valve in the fuel supply line that had been overlooked

during previous troubleshooting. This valve was overlooked

because maintenance history records indicated that it was

installed on the 1B HPSW diesel and not in the 1A diesel and the

fact that this particular valve has the appearance of a line

fitting rather than that of a valve. Upon cleaning this valve

the diesel starting problems were apparently solved (e.g., the

diesel was successfully started on July 13, 14, 15, 17, and 19

with no intervening failures).

Eighty-one modifications (facility changes) were completed during

this SALP evaluation period. Most of the modifications were

directed toward improving plant operations. However, several

modifications were directed toward enhancing plant safety by

responding to recommendations by the licensee's Safety Review and

Operating Review Committees. Examples of facility changes that

should enhance plant safety are highlighted below:

a. The elastomeric components of the upper control rod drive

mechanical seals were upgraded. This change should improve

plant reliability and safety because the seals are more

resistant to fluctuations in operating temperatures. This

change has not been implemented on all control rod drive

mechanisms; however, the new material has been placed in

stock, and will be used on the remaining units when routine

maintenance is performed.

b. A turbocharger was added to the 1A High Pressure Service

Water Diesel Engine. This modification was aimed at improv-

ing the diesel engine's reliability and at increasing its

rating, thereby assuring ample service water flow.

c. Reactor wide range water level transmitter 50-42-305 was

replaced with a new unit having a local rather than a remote

amplifier. The new equipment is qualified to withstand the

postulated harsh environment and is judged to be superior to

the original equipment.

d. The electronics of the component cooling water and turbine

condenser liquid radiation monitors were upgraded to provide

more sensitive and reliable radiation monitoring.

Staffing in the maintenance area is adequate. Personnel are

experienced and knowledgeable. Authorities and responsibilities

are well defined. Maintenance personnel have received training

on plant systems and overall plant operations. This training

contributes to their understanding of the effect of their activi-

ties on the plant operation. Maintenance procedures are generally

adequate and adhered to. Management involvement is good at both

the site and corporate levels, as evidenced by the many plant

4: upgrade modifications performed. Management is responsive to NRC

initiative and concerns. -They exhibit a positive and cooperative

attitude.

The age of many components at LACBWR and the fact that the

nuclear' steam system suppler (Allis-Chalmers) is no longer a

' viable source for replacement of parts that are wearing out,

suggests that the licensee should upgrade and implement a more

F' extensive and systematic preventive maintenance program. 'This

program should include a systems engineering evaluation for the

explicit purpose of establishing priorities for refurbishment

-

or replacement of components reaching their end-of-life. Of the

17 RPS Trips which occurred during this evaluation period, 13

.

were caused by mechanical equipment problems (6 at power levels >

72% and 7 at power levels < 1%). This strongly' suggests the need

l for improvement in the preventive and corrective maintenance

4 areas. It is recognized that many actions were initiated during

this evaluation period to reduce the number of such problems, but

the effectiveness of these actions was not current during this

,

appraisal period. The major constraint associated with such a PM

program is, of course, the potential negative impact of ALARA

'

1 considerations. Accordingly, the PM program should, to the

maximum degree practicable, use mock-ups prior to undertaking

, complex maintenance activities.

'

2. Conclusion

The licensee's performance regarding maintenance, especially as

it relates to failure analysis, and the effectiveness of the

,

preventive maintenance program appears to have declined from that

l of the previous SALP evaluation and should be given additional

attention by the licensee. On the other hand the licensee's

,

modification program is~ considered very effective in not only

improving operations but also in enhancing safety. However, due

to the large number of equipment failures which have resulted in

reactor scrams and other reportable events the overall performance

l- in this area is rated Category 3.

i. -

l 3. Board Recommendations

,

More attention by the licensee and by the NRC is required in the

area's of preventive maintenance and corrective maintenance.

D. Surveillance and Inservice Testing

1. Analysis

!

! Routine inspections were conducted in this area by the resident

! inspector and two inspections were conducted by region-based

inspectors to assess the licensee's performance, and compliance

with the relevant procedures and programs, licensee requirements

and applicable regulations. The resident inspector witnessed

,

test activities, reviewed procedures and test data, and verified

on a spot-check basis that surveillance tests were performed as

required.' The region-based inspectors performed in-depth inspec-

tions of the licensee's-program for inservice testing of pumps

and valves, and of.startup core performance testing. .None of

these inspections resulted in violations or deviations.

The surveillance activities inspected were performed in a very

professional manner and found to be well managed. No surveillances

were missed during the period. For example, the. manner by which

surveillance activities are conducted clearly indicate that the

authorities and responsibilities in this area are clearly defined,

personnel involved in this area are very knowledgeable and

proficient in performing their assigned tasks, and prior planning

has been well developed. The licensee's training program in this

area stresses the need for adherence to procedures, thereby

assuring that the surveillance actions do not compromise plant

safety or plant operations. Surveillance records were found to

be complete, well maintained and readily available. Likewise,

the licensee's audit reports were found to be complete and

thorough.

The licensee has implemented an inservice testing program and was

conducting testing in accordance with the requirements of the

ASME Code. Modifications or revisions to the inservice testing

program, associated test procedures and test acceptance criteria ,

are reviewed by the Onsite Review Committee, including representa-

tives from Operations, Quality Assurance and plant technical

staff, to insure compliance with Code requirements and that plant

equipment and systems are not unnecessarily challenged.

The licensee responded to technical issues in a timely manner

with appropriate justifications and supportive documentation.

The licensee was in the process of assigning acceptable

instrument accuracy values to plant instruments for which no

3

manufacturer's specified values are given.

l

The licensee responded to NRC identified concerns in an

'

appropriate and timely manner. Inconsistencies identified during

the inspection were addressed and either resolved, or reasons for

delay of resolution and estimated dates of completion were

  • *

identified prior to the end of the inspection.

l

! Current staffing is adequate to administer and implement the

,

inservice testing program at LACBWR. However, it was noted that

plant administrative practices and knowledge of past events which

affect implementation of the program appear to reside with one

< individual. The loss of this individual from the LACBVR staff

l

could adversely impact consistency and adherence to Code require-

!

ments associated with surveillance / inservice testing. Members of

,

the licensee's staff were knowledgeable of inservice testing

i requirements and test methods. Interviews with members of each

operating shift crew and their shift supervisors indicate that

licensee training has produced consistent test methods and test

documentation.

2. Conclusion

The licensee's overall rating in this functional area is Category 1,

the same rating achieved during the last SALP period.

3. Board Recommendations

None.

E. Fire Protection

1. Analysis -

The resident inspector performed routine inspections in this area

during this evaluation period, including evaluation of potential

fire hazards, plant housekeeping and cleanliness and compliance

with LACBWR's fire protection plan. The inspections indicated

excellent housekeeping practices, indicating a marked improvement

from that of a previous inspection. One special inspection was

performed by region based inspectors and their consultants during

this evaluation period to verify the adequacy of the facility's

post fire safe shutdown method (Section III.G., J, 0, and L of

Appendix R), and other fire protection features and modifications.

One violation was identified:

Severity Level V - Failure to hydrostatically test fire

extinguishers (409/85013).

Concerns were raised during the special inspection regarding:

  • The sprinkler system, fire detectors and the partial height

fire wall between the fire pumps in the cribhouse did not

provide reasonable assurance (as described in the Supplemen-

tal Safety Evaluation Report, dated March 23,1983) that at

least one fire pump would remain functional, should a

disabling fire occur in the cribhouse. The licensee has

acknowledged this concern and corrective actions are

expected in this area. Some corrective actions in this area

have been taken by the licensee. For example, the licensee

has relocated the starting battery for the 1B high pressure

service water pump, which is also a fire pump, to satisfy

the Appendix R commitment. This relocation resolved the

concern associated with the height of the fire wall between

the fire pumps.

  • The inspectors observed that no area wide fire detection

system existed in the control room as specified by Section

5.7.4 of the SER; however, the license condition related to

15

.-

the completion of facility modifications to improve the fire

protection program did not include installation of an area

wide fire detection system in the control room. The licensee

committed to installing an area wide fire detection system

in the control room at the exit meeting of July 11, 1985.

- * Adequate control of combustibles was observed by the

inspectors, although special mention was made regarding the

storage of combustible materials in the electric equipment

room and implied throughout the plant. The inspectors

indicated that combustible materials not essential for

routine operation should be removed. Improvement in this

area is desirable.

Also reviewed during this inspection was the fire brigade

composition and training portion of the licensee's fire protec-

tion program. The fire brigade composition and training

conformed to the guidelines of Appendix A to Branch Technical

Position 9.5-1, although four brigade training program

implementation weaknesses were identified. One additional

concern noted regarded the current licensee's policy on normally

designating the Shift Supervisor as the fire brigade leader.

This practice is discouraged by Appendix A. The licensee was

encouraged to reconsider the use of the Shift Supervisor as the

fire brigade leader.

.

Management involvement and support of their staff during the

inspection was appropriate to the circumstances and the licensee

was willing to listen and discuss inspector raised concerns.

Observations by the resident inspector of site conditions

generally indicated excellent housekeeping practices. Problem

areas identified were promptly corrected and do not appear to

be repetitive. Management and staff appear to take a positive

attitude towards housekeeping and fire prevention.

2. Conclusion

The licensee is rated Category 2 in this area with continued

strength in the area of housekeeping.

3. Board Recommendations

None.

F. Emergency Preparedness

1. Analysis

Two inspections were conducted during the SALP period, one

routine inspection and one exercise. The routine inspection was

conducted in April 1985 and resulted in the closing of 14 open

l

i

16

i

.

items and the opening of five more. However, the five new items

were of a minor nature and did not involve any violations. Two

of the open items dealt with inconsistencies between the newly

revised Emergency Preparedness Plan and the Emergency Plan

Procedures. Two more items related to emergency equipment which

was satisfactory but not adequately described in the Plan, in one

case, and in the other case required upgrading based on ALARA

concerns. The fifth open item referred to the hiring of an

additional person, part of whose functions would have been to

assist the Emergency Planning Coordinator.

This latter personnel need has been resolved by replacing the

previous Emergency Planning Coordinator with a more qualified

individual who has an SR0 license. The licensee believes that

the appointment of a more qualified Coordinator eliminates the

need for an assistant.

The licensee's annual exercise was conducted in June 1985 and

resulted in two weaknesses regarding the notifications to State

and local agencies. The initial notification for the Site Area

Emergency was completed within 27 minutes rather than the

required 15 minutes and the notifications did not always specify

whether a release was taking place, as specified by the licensee's

Emergency Plan.

Management control, measured by the number of violations and open

'

items, has improved since the SALP-5 period but still has room

for further improvement. For example, in the May 1984 routine

inspection, nine inspection-related open items were closed, but

seven new items were opened, four of them being violations. Thus,

the April 1985 routine inspection, mentioned above, was an

improvement since 14 Open Items were closed and only five items

(none of them being violations) were opened. However, the open

item concerning inventories that was found in April 1985, was

never corrected during the SALP-6 period and led to a subsequent

violation in 1986.

During the last two to three years there has been a noticeable

improvement in the licensee's responsiveness to NRC concerns.

There are no long-standing regulatory issues attributable to

the licensee. The licensee is generally timely in its responses

but there are still exceptions to this. For example, the June 25,

1985 exercise resulted in a weakness in their notification

-

performance after declaration of an emergency. Less than 30 days

later during a real event (loss of Offsite power) the licensee

failed to notify the State of Minnesota within the required 15

minutes. Timely corrective action on the exercise weakness would

have prevented the notification problem identified during the

actual event.

The enforcement history is improving. In the previous SALP

period there were five violations, whereas there were none

during this SALP period.

17

.

' Staffing at the management level has been unchanged, and the

selection of an experienced SR0 for the Emergency Planning

Coordinator position should be an improvement in staffing.

Training and qualification effectiveness is generally good as

demonstrated by the elimination of any violations during the

SALP period. However, documentation and record keeping of

training must be further improved. The methodology the licensee

used to track completed training resulted in three operators

missing their annual emergency preparedness training by up to

three months.

2. Conclusion

The licensee is rated Category 2 in this area. The licensee

was rated a Category 2 in the last SALP period.

3. Board Recommendations

None.

G. Security

1. Analysis

-

Two security inspections were conducted by region-based physical

security inspectors during the assessment period. Both were

routine inspections. Additionally, the Resident Inspector

routinely conducted observations of security activities. Five

violations were identified relative to the security program as

follows:

a. Severity Level IV - A security screen was inadequately

fastened to a vital area structure (409/85016).

b. Severity Level IV - Search hardware failed to perform as

required (409/85016).

c. Severity Level IV - Some alarm zones failed to perform as

i

required (409/85016),

d. Severity Level IV - Failure to implement adequate

compensatory measures (409/86004).

e. Severity Level V - Failure to maintain a clear isolation

zone (409/85016).

Allegations were received by Region III that dealt with security

at the facility involving compensatory measures not being

l

implemented, alarms not being recognized; events not being

reported to the NRC; and vital area doors left open. The alleged

events occurred in 1982 and did not involve current deficiencies.

They could not be fully substantiated. No violations were cited

as a result of any of the allegations.

Weaknesses identified by NRC inspectors were noted that did not

involve violations in the areas of assessment aids, protected

area physical barriers, security system maintenance, and

. discrepancies between the security plan and the contingency

plan. When the violations and weaknesses were identified, the

licensee usually took corrective action in a timely and

effective manner.

Some weaknesses and violations were not self-identified.

Although they were not major in nature, they were recognizable

and could have been corrected, had they been identified. Since

there was an increase in cited violations from the previous SALP,

the licensee should consider a closer and more thorough management

review of the system to identify potential problem areas and

correct them before they become more significant.

Positions within the security organization are identified and

responsibilities are well defined. In November 1985, a new

Security Director was hired to replace the former Security

Director who was promoted to the corporate office. The new

-

security director has established and maintained good

communications with Region III safeguards staff.

Events reported under 10 CFR 73.71 were properly identified and

analyzed. There were six reported events which dealt with

computer problems, such as loss of primary power and protected

area alarm malfunction. Records are generally complete, well

maintained, and available.

Review of the security training program and its effectiveness

was limited. Those portions of the training records reviewed

were adequate. No major problems in performance were noted

which indicated significant weaknesses in training.

There were no technical issues involving physical security from

a safety standpoint which required resolution during this

assessment period.

Management's support for the security program has continued and

was made evident by the purchasing of a walkthrough metal

detector, hand-held explosives detectors, CCTV cameras, hand-held

radios, and upgrading the backup security power supply.

In summary, management's support for the program has increased.

The effectiveness of that support may be increased through a

more aggressive program for self-identification of potential

problems and reviews to determine cost effective protective

!

19

!

t

.

. improvements to the program. This has been shown in the

upgrading of some security equipment. The number of violations

and weaknesses have increased since the previous SALP period;

however, they were of a minor significance.

2. Conclusion

The licensee is rated Category 2 in this area, which is the same

rating achieved in the last assessment period. However, the

overall licensee performance is declining.

3. Board Recommendations

None.

H. Outages

1. Analysis

Evaluation of this functional area was based on the results

of inspections conducted by the resident inspector involving

the scheduled 1986 refueling outage, an inspection by a

region-based inspector regarding the review of selected

procedures and equipment checkouts associated with the 1986

refueling outage, and a special inspection by region-based

inspectors in response to potential damage to the core spray

bundle during the refueling outage. The inspections included

observations of maintenance, refueling, and post-maintenance

conducted during the outage and the review of selected

administrative and procedural requirements. No violations

of deviations were noted for this area.

The licensee completed its 1985 and 1986 refueling outages during

this SALP period. However, because there was no resident

inspector on site during the 1985 refueling outage, it is not

discussed in this report. The 1986 refueling outage was

initially scheduled to be accomplished in approximately 42 days;

however, because of several problems experienced during the

outage, the actual refueling duration was 70 days.

The inspection activities performed by the region-based inspector

included a review of fuel handling equipment checkout and fuel

~

transfer procedures, surveillance test procedures and operating

manuals, observation of fuel handling activities, verification of

performance of fuel transfer accountability records and review of

surveillance test results. The findings associated with this

inspection indicated that (i) licensee performance was properly

managed and effective, (ii) fuel movement activities were conduc-

ted in strict adherence to approved procedures and without error,

and (iii) procedures used during the refueling outage were

technically adequate and properly approved.

As previously indicated, the licensee experienced several problems

during the 1986 refueling outage that increased its duration by

20

.

'

about 30 days. Some of the problems were due to personnel error

and others to equipment malfunctions. The more significant of

these events and their impact on the outage are highlighted in

the paragraphs that follow.

On March 7, 1986, one day prior to the scheduled refueling outage,

the reactor scrammed when a 2400 volt reserve feed breaker failed

to close while transferring plant loads from the main source to

the reserve source. Although the actual increase in outage time

accrued to this event is unknown, it adversely impacted the

refueling outage by diverting electrical maintenance personnel

from scheduled PM activities to corrective maintenance activities

on the breaker, thereby placing an additional unplanned work load

on the staff during a hectic period.

On March 12, 1986, while the upper cavity was being flooded,

water leaked from a thermocouple conduit that penetrates the

shield wall into containment. This event was due to personnel

error and poor communications between maintenance and operating

staff personnel. (i.e., A wrong sized thermocouple plug was

installed in the penetration conduit; however, this fact was not

clearly communicated to the operating staff. Thus, the cavity

was being filled while a leak path existed from the cavity to

containment). This event delayed the outage by about one day and

,

also created a contamination control problem inside containment.

On March 15, 1986, while control rod handling was in progress,

the control rod in position 19 was found to be unlatched from its

drive mechanism. The control rod drive mechanism for this rod

had been last installed in September of 1984; therefore, it was

reasonably assumed that the rod had been unlatched since that

date. Upon finding the unlatched rod, a test program was insti-

tuted to verify that all the other rods were latched. Although

this event was not complicated, i.e., the reinstallation of

unlatched rod was straightforward, as was the testing to ensu

that all rods were latched, it added about three days to the

refueling outage.

On April 3, 1986, while lowering the high pressure core spray

(HPCS) bundle into the reactor vessel, the bundle struck the

vessel's internals on at least two occasions. On April 4, while

attempting to bolt down the bundle it did not seat properly and

was sitting about one-half inch higher than it should. The

bundle was, therefore, removed fron the vessel and returned to

the fuel element storage well and inspected. The inspection

revealed that the four outermost tubes of the bundle had been

bent inwards about 20 to 35 degrees. Because of the concern

regarding damage to a safety system, a special inspection was

conducted by region-based inspectors. Based on their review of

this event, the inspectors concluded that the corrective

actions taken were acceptable and that no safety concerns or

violations existed. (NOTE: The actual reason for the seating

.

problem was not determined until August, while the plant was

shutdown to repair a pipe leak. While removing fuel, the

licensee found a bent handle on one of the fuel assemblies.

Subsequent examinations and review of video tapes revealed that

the affected fuel assembly had not been properly seated during

,

the 1986 refueling outage. Thus, the fuel assembly's

protruding handling obstructed the initial seating of the HPCS

bundle). Several factors contributed to this event, including

the constraints associated with working in a high radiation

area, poor visibility, poor crane alignment markings, and

perhaps undue pressure. These factors ultimately led to what

can be euphemistically called personnel error. This incident

adversely impacted the refueling outage by adding about ten

days to the outage.

In addition to the incidents highlighted above, several other

events occurred during the 1986 refueling outage. The cumulative

effect of these events was to increase the outage duration about

five days. Said events include the dropping of an underwater

light shield and clamp into the reactor; the breaking of the

source connecting bolts while the source was being moved from the

storage well to the reactor such that the lower third of the

source (the plug end) landed in the reactor; the damaging

(twisting) of the upper band of a new fuel assembly while it was

being lifted from its storage position; and a small fire that was

quickly controlled in the lagging of the 18 forced circulation

pump's discharge piping.

Although the licensee does not have the same size staff as many

other licensees, it does have knowledgeable and experienced

staff member from each plant discipline who routinely work

together to provide the planning and scheduling function for

the plant. This approach has worked well over the years. In

addition, the licensee has experienced good control over outage

work packages. This is partially due to the fact that most of

the outage work is done by licensee personnel, with very little

work being performed by contractors. However, when contractor

personnel are utilized, adequate communication and supervision

is provided to assure control over their work activities.

Some of the problems experienced during the 1986 refueling

outage could have been prevented by more diligent attention

to detail by both maintenance and operating personnel.

Likewise, improved communications between maintenance and

operating management personnel could have improved the overall

performance during the 1986 refueling outage.

2. Conclusion

The licensee is rated Category 3 in this area.

3. Board Recommendations

Because of the number of reportable events (10) experienced ~during

the 1986 refueling outage and the repetitive nature of some of

the events, it is recommended that LACBWR management be more

directly involved in the-day-to-day activities during refueling

outages. Said involvement should be aimed at assuring that the

refueling activities are performed properly, that appropriate

administrative controls are implemented and that clear lines of

communications are maintained between maintenance staff and

operating staff.

I. Quality Programs and Administrative Controls Affecting Quality

1. Analysis

Evaluation of this functional area was based on the results of

routine inspections conducted at the Lacrosse Boiling Water

Reactor (LACBWR) by the resident inspector and two inspections by

region-based inspectors. The inspections for this area included

routine inspections regarding administrative controls for

maintenance and operations and deviation reports with respect to

the Quality Assurance Plan and the role of the Quality Assurance

Staff. No violations or deviations in this area were noted.

The first region-based inspection for this area was conducted in

the beginning of the SALP period and was aimed at evaluating this

functional area as it relates to (i) the Offsite Review Committee,

(ii) the Offsite Support Staff, and (iii) the Nonroutine Reporting

Program. The licensee was essentially in a transition status

during this early part of the SALP period, e.g., actions had been

initiated or planned in those areas which would result in minor

changes in the licensee's commitment or in its performance to

requirements. These actions and their results were not expected

to have any major safety significance.

The second region-based inspection for this area was aimed at

evaluating LACBWR's maintenance, QA/QC administration, tests and

experiments, receipt, storage and handling, and procurement. The

inspector verified that the licensee had implemented a written

program relative to maintenance activities and QA/QC administra-

tion that was in conformance with Technical Specifications,

regulatory requirements, commitments and industry guides or

>

standards.

The licensee's quality programs and administrative control

affecting quality gave evidence of prior planning, assignment of

priorities, and decision making that was usually at a level to

ensure adequate management review. The responsiveness to NRC

initiatives was timely with acceptable resolution to concerns.

Events were usually identified and reported in an accurate and

timely manner.

23

. l

- The licensee's policies in the areas inspected are adequately

stated and understood, and the procedures are adequately defined

and stated for the control of those activities. Audits have been

complete and thorough. Corporate management was usually involved

in site activities, and management attention and involvement are

evident and show concern for nuclear safety. Quality program

activities appear to be controlled adequately. The implementation

of the QA program is acceptable as reflected in overall plant

performance.

2. Conclusion

The licensee is rated Category 2 in this area.

3. Board Recommendations

None.

Appendix J Leak Testing

During the SALP period, 61 licensing actions were .

completed which consisted of 45 plant-specific actions,

10 multi plant actions, and six TMI (NUREG-0737) actions.

A very important licensing activity completed during the

review period was the issuance'of a primary property

damage insurance exemption for LACBWR. This achievement

is noteworthy because LACBWR is the first utility to

provide adequate technical justification to support such

an exemption at the Commission level.

In addition, the project manager and other members of the

NRR staff participated in reviews at the plant concerning

the post accident sampling system, systematic evaluation

program topics as well as an Appendix R fire protection

audit.

b. Management Involvement and Control in Assuring Quality

During this rating period, the licensee has demonstrated a

very active role in licensing-related activities. Strong

management involvement has beea especially evident where

issues have potential for substantial safety impact and

extended shutdowns. Licensee management actively partici-

pated in an effort to work closely with the NRC staff and

management to promote a good working relationship. The

majority of submittals were consistently clear and of high

quality. The licensee management frequently participated

in meetings in Bethesda on short notice.

There is one area which indicates a lack of management

attention, and that is the setting of priorities of

licensing actions to be evaluated by the NRC staff.

During the winter 1986 refueling outage management at the

site informed the NRC staff the top priority licensing

action were those related to restart and at the same time

the Lacrosse headquarters management informed the NRC

staff that the property damage insurance exemption was the

highest priority licensing action. This conflict almost

resulted in the licensee having to request an emergency

technical specification change to allow startup. This

conflict and other communication problems between the staff

-

and the licensee were brought to the attention of the

licensee's management. The licensee's management has worked

out the internal problems and worked closely with the NRC

staff in the last three months of the evaluation period to

correct these problems. We recognize a strong improving

trend.

c. Approach to Resolution of Technical Issues from a

Safety Standpoint

The licensee almost always demonstrated a strong

understanding of the technical issues involved in licensing

actions and proposed technically sound, thorough, and timely

resolution. However, there have been issues where the

licensee's approach was good, but the licensee did not

. . thoroughly understand NRR staff guidance. Once the staff

guidance was fully explained, the licensee proposed timely

solutions which were technically sound and exhibited proper

conservatism. For a few issues, full explanation of the

staff guidance required an above average amount of staff

effort. Examples of such issues are post accident sampling

system, ECCS technical specifications and purge and vent.

d. Responsiveness to NRC Initiatives

The licensee has been responsive to NRC initiatives. During

the rating period, it made every effort to meet or exceed

26

I

.

'

commitments. Responsiveness by the licensee facilitated

timely completion of staff review of a large number of

licensing actions and thus substantially reduced the

licensing backlog. The licensee's quality of license

amendment requests, especially the "no significant hazards

consideration" improved significantly after the " counter-

parts" meeting held on January 30, 1986 in Bethesda, where

this topic was discussed in detail. The licensee has

responded promptly and accurately to various surveys

conducted during the reporting period.

In addition, the licensee at the staff's request has

provided submittals for the staff in a very short turn-

around time. This was especially evident in the licensee's

response to the staff's request for the LACBWR status on

the implementation of generic requirements. The licensee

was required to review a vast amount of documentation and

provided the NRC staff with a timely response which was of

high quality,

e. Staffing

The licensee has maintained adequate licensing staff to

assure timely response to the NRC needs.

During this period, the licensee's performance was found to be

above average to excellent overall. Management attention and

involvement was generally as expected. This was evident in both

the safe and efficient operation of the facility. Staffing

levels and quality were adequate. Communication levels between

the operating staff and proper management were established and

generally effective. The licensee has been, in most cases,

effective in dealing with significant problems and NRC initiatives.

The licensee's attention to housekeeping appears to have been

excellent. The licensee's efforts in the functional area of

Licensing Activities has significantly improved during this

evaluation period. This is reflected in the quality of work,

attention to NRR concerns and involvement of senior management.

DPC was an active participant at the counterparts meeting of

January 30, 1986, in Bethesda, Maryland.

2. Conclusion

The overall rating for the functional area of licensing

activities is Category 1.

3. Board Recommendations

None.

K. Training and Qualification Effectiveness

1. Analysis

A training effectiveness inspection conducted during the

assessment period identified no generic training-related problems.

The training feedback of lessons learned from plant events was

accomplished primarily in supervisor meetings and by required

reading which appeared adequate. However, licensed operators did

express a desire for more input on general plant problems. The

training programs for non-licensed personnel were primarily based

on on-the-job training (0JT) with minimal classroom instruction.

The requalification training for licensed operations consisted of

required lectures conducted on a 24-month cycle and simulated

manipulations. Initial qualification training consisted of

attendance at the requalification lectures and 0JT. The success

rate for initial licensing examinations in the past has been

consistent with national averages over the last several years.

However, during this evaluation period the success rate declined

to less than the national average when only seven of the eleven

candidates passed their examinations.

It was determined by the inspection and operator licensing

staffs that the Lacrosse operator license training program did

not provide the three months of on-shift training for senior

reactor operator candidates for the specific purpose of preparing

them for Shift Supervisor duties. It was also determined that

the applications submitted by two reactor operator candidates

contained inaccurate information and that certain training

credited to them was not relevant to their license training.

It was also determined that training deficiencies existed for

previous senior reactor operator candidates.

These issues were discussed at two meetings held on May 7 and

May 30, 1986, in the Region III office with management represen- -

tatives from Dairyland Power Cooperative and the NRC. During

the May 30 meeting the licensee agreed to implement a documented

on-shift training program for senior reactor operators and to

provide this training to currently licensed senior reactor

operators identified in a letter dated June 5, 1986, from

Mr. James W. Taylor, General Manager, Lacrosse.

Based upon the examination results during the assessment period

and the implementation of the on-shift training program for

senior reactor operators, the Lacrosse license training program

is considered satisfactory.

A separate evaluation of radiological controls training indicated

that the licensee is developing a formal health physics technician

training / retraining program. Training is performed mainly by

station professionals and by required self-study. The training

has contributed to an adequate understanding of work and fair

adherence to procedures with a modest number of personnel errors.

The licensee has made all required submittals to INP0 i

regarding the subject training areas. Licensee management

attention to the training area appeared to be adequate except

for the misunderstanding of SRO candidate training requirements.

  • Proximate cause is the cause assigned by the licensee

according to NUREG-1022, " Licensee Event Report System."

    • NUREG-1022 only requires a cause code for component failures.

In the SALP 5 period, the licensee issued 32 LERs in 18 months

for ar, issue rate of 1.8 per month. In the SALP 6 period the

licensee issued 39 LERs in 18 months for an issue rate of 2.2

per month. By comparison to like plants (to which there are

few) the number of LERs is high.

Sixteen of the LERs were related to scrams, four were due to

unsampled water being discharged, three due to the high pressure

service water diesel, two for degraded fire barriers, seven for

-

ESF actuations, two due to leakage test failures, one was because

the HPCS bundle was b?nt, one due to an unlatched control rod,

one due to a cracked valve, one due to a wrong alternate core

spray lineup, and one because of an apparent failure to scram.

Three events reported under 10 CFR 50.72 requirements were

considered significant and were discussed at the Operating

Reactor Events Briefing (OREB) in Headquarters. The first

related to a loss of offsite power and a scram that occurred on

October 22, 1985. This event was classified an unusual event.

This event occurred due to maintenance personnel error when the

plant was at 98% power. The scram was normal without complica-

tions and the emergency diesel generator started ano powered all

required loads normally. The event was promptly reported within

16 minutes of its occurrence, and within an hour, offsite power

was restored and the unusual event terminated. The second event

occurred on October 23, 1985 and related to an apparent failure

to scram upon receipt of a high flux signal. The failure to

scram was caused by electrical failure that caused a malfunction

of the reactor protection system (RPS). the control rods were

manually inserted to bring the reactor subcritical. The plant

was placed under alert conditions for a brief period, and all

concerned agencies were notified promptly. The third event

discussed at the OREB occurred on March 6, 1986 and related to

the ignition of the turbine offgas stream during sampling

activities.

.

The office for Analysis and Evaluation of Operational Data (AE00)

reviewed the LERs for this period and concluded that, in general

the LERs are of above average quality based on the requirements

contained in 10 CFR 50.73. However, they identified some minor

deficiencies. A copy of the AE0D report has been provided to the

licensee so that the specific deficiencies noted can be corrected

in future reports.
