            I.    INTRODUCTION
            The Systematic Assessment of Licensee Performance (SALP) program is an integrated
            NRC staff effort to collect the available observations and data on a periodic basis
            and to evaluate licensee performance based upon this information. The SALP is sup-
            plemental to normal regulatory processes used to ensure compliance with NRC rules
            and regulations. The SALP is intended to be sufficiently diagnostic to provide
            meaningful guidance to the licensee's management to promote quality and safety of
            plant construction and operation.
          An NRC SALP Board, composed of the staff members listed below, met on March 2,1989,                            l
            to review the collection of performance observations and data to assess the 11cen-
            see performance in accordance with the guidance in NRC Manual Chapter 0516, "Sys-
            tematic Assessment of Licensee Performance " A summary of the guidance and evalu-
            ation criteria is provided in Section III of this report.
          This report is the SALP Board's assessment of the licensee's safety performan'ce
          at the Three Mile Island Nuclear Generating Station, Unit 1 (TMI-1) from November
            1, 1987 through January 15, 1989. The summary findings reflect a 15-month assess-
          ment period.

                        'I.A Licensee Activities
                          During this. period, the licensee operated TMI-1 essentially at full power, except
                          for a refueling outage and as noted in Section II.C and II.D (Forced Outages and
                          Plant Transients). This reflected ten transition periods between' power operations  j
                          and hot (or cold) shutdown in addition to the two transition periods for their
l.                        refueling outage. The one trip during this' SALP period occurred on October 30,
L'                        1988 (the last one being on September 16,1987). A scheduled sixty-foer day re-
                          fueling outage started June 17, 1988, and the. licensee completed it about five days !
                          ea rly..
                          Major safety-related work completed during the refueling outage was: "8" make-up
                          pump overhaul; seal replacement for four reactor coolant pumps; steam generator
                          mechanical cleaning and eddy current testing; installation of Regulatory Guide (RG)  j
                          1.97, Instrumentation; fuel handling bridge modification; upgrade power supply for
                          the Integrated Control System /Non-Nuclear Instrumentation System (ICS/NNI).
                          At the beginning of this period, the licensee's maintenance department at TMI-1
                          was in the process of reorganizing into a Materiel Department. Four major groups
                          in this department were to perform the following functions: plant materiel (cor-
                          rective and preventive maintenance implementation), planning and scheduling, ma-
                          teriel assessment and administration.
                        Also, during this period, the licensee implemented a corporate reorganization,
                          establishing a new division with Vice President for Quality and Training.
                          Self-assessments were completed in the maintenance and technical support functional
                          areas.
                          I.B Direct Inspection and Review Activities
                          Four NRC resident. inspectors were assigned to the site (TMI-1 and 2) throughout
                        most. of the assessment period. Total NRC inspection effort was 4693 hours (4107
                        hours per year). See Table I for functional area expenditures.
                          Special team inspections were: Outage Team Inspection (88-17) and Emergency Pre-
                        paredness Exercise (88-28).
                        Also, the Office of Nuclear Reactor Regulation (NRR) sent a team to review the
                        design of electrical power distribution.
                        Six violations (five Severity 4, one Severity 5) were issued. These are listed
                          in Table 2.

            and corrective action implem ntation although effective, sometimes result in a
            lengthy process. A recent teworthy improvement in this process is the high qual-
            ity of the human performa ce evaluations of selected incidents. Although overall
            improvements have be    s  de in procedure adherence, progress in these achievements

              II.A Overview
              The licensee operated TMI-1 in a safe manner throughout the rating period. In all
              functional areas, programs are well established. These programs are carried out
              by knowledgeable personnel who are appropriately trained.
              During the period, the operating record at the facility was excellent. Overall
              plant material condition remained good. One reactor trip occurred as a result
              of equipment failure. Operators responded alertly to other condition: such as
              equipment malfunctions to prevent plant transients. The excellent operating
              record is a reflection of a high level of performance in plant equipment material
              condition, operator performance, and overall management oversight of the facility.
              In general, management involvement in maintenance and surveillance was effective
              and outage management was excellent. Several important initiatives have been taken
              including a restructuring of the maintenance department. The principal weaknesses
              observed were in specific job olanning and increased personnel errors. This
              led to the decline in performar,ce in the maintenance area noted during the
              period.
              Strong programs continue in the radiological controls, emergency preparedness,
              and security areas. Improvements in the emergency preparedness area in response
              to NRC concerns and communication problems in the last SALP were positive 3nd
              returned that program to its previous strong level of performance.
              Engineering and technical support performance improved; this was most notable in      I
              engineering support to the 7R refueling outage. A technical support self-assess-
              ment was completed and corrective actions were begun.
              Licensee programs to identify and correct problems are thorough and the various
              review groups are active in assessing plant performance. Root cause determination
              and corrective action implementation although effective, sometimes result in a
              lengthy process. A recent noteworthy improvement in this process is the high qual-
              ity of the human performance evaluations of selected incidents. Although overall
              improvements have been made in procedure adherence, progress in these achievements
              has been slow, particularly in administrative controls.
              Overall, licensee performance during this period continued to be very good. The
              refueling outage was a noteworthy example of this performance. Completion of
              corrective action programs underway and management attention to problems existing
l            or identified in the future should continue this progress.

                              This SALP report incorporates the recent NRC redefinition of the assessment func-
                              tional areas. Changes include combining the previously separate maintenance and
                                surveillance areas and addition of the safety assessment / quality verification area.
                              The safety assessment / quality verification section is largely a synopsis of obser-
                              vations in other functional areas. Additionally, the fire protection, licensing,
                              refueling / outage, training, and assurance of quality areas have been incorporated
                                into the remaining functional areas as appropriate.

                      Licensee performance was assessed in selected functional areas significant to nuc-
                      lear safety and/or the environment. The following were evaluated, as applicable,
                      to assess each area.
                    ' 1.    Assurance of quality, including management involven,ent and control.
                      2.    Approach'to the' resolution of technical issues from a safety standpoint.

                      7.    Effectiveness of training and qualification.
                      Each functional area was rated as being one of the following.
                      1.    Category 1.    Licensee management attention and involvement are readily evident
                            and place emphasis on superior performance of nuclear safety or safeguards
                            activities, with-the resulting performance substantially exceeding regulatory
                            requirements. Licensee resources are ample and effectively used so that.a
                            high level.of plant and personnel performance is being achieved. Reduced NRC
                            . attention may be appropriate.
                    2.    Category 2.    Licensee management attention to and-involvement in the perform-
                            ance of nuclear. safety or safeguards activities is good. The licensee has-
                            attained a level of performance above that needed to meet regulatory require-
                            ments.    Licensee resources are adequate and reasonably allocated so that good
                            plant and personnel performance is being achieved. NRC attention may be                                ,
                            maintained at normal levels.                                                                            i
                    3.    Category 3. Licensee management attention to and involvement in the perform-
                            ance of nuclear safety or safeguards activities are not sufficient. The lic-
                            ensee's performance does not significantly exceed minimum regulatory require-
                            ments.    Licensee resources appear to be strained or not effectively used.

            The SALP Board'also considered assigned performance trends for the last quarter
            of the SALP period. A trend is assigned if definitely discernible, if the SALP
            Board concludes that its continuation might change the performance level, and if
            considered necessary to either focus attention on declining performance of acknowl-
            edge improving performance. .The SALP trend definitions are:
            Improving: Licensee performance was determined to be improving near the close of
            the assessment period.
          Declining:        Licensee performance was determined to be declining near the close of
,
          the assessment period and the Itcensee had not taken meaningful steps to address
            this pattern.
          A trend is assigned only when, in the opinion of the SALP Board, the trend is sig-
          nificant enough to be considered indicative of a likely change in the performance
          category in the near future. For example, a classification of " Category 2, Im-
          proving" indicates the clear potential for " Category 1" performance in the next
          SALP period.
            It should be noted that Category 3 performance, the lowest category, represents
          acceptable, although minimally adequate, safety performance. If at any time the
          NRC concluded that a licensee was not achieving an adequate level of safety per-
          formance, it would then be incumbent upon NRC to take prompt appropriate action
          in the interest of public health and safety. Such matters would be dealt with
          independently from, and on a.more urgent schedule than, the SALP process.
          It should also be noted that the industry continues to be subject to rising per-
          formance expectations. NRC expects licensees to use industry-wide and plant-speci-
          fic operating experience actively in order to effect performance improvement. Thus,
          a licensee's safety performance would be expected to show improvement over the
          years in order to maintain consistent SALP ratings.

          The previous SALP report rated this area as Category 2 with a need to further im-
          prove procedural compliance, develop documentation and evaluation for minor opera-
          tional events, enhance interfaces between operations and engineering / test personnel
        . under schedular pressure. Positive aspects identified in this functional area in-
          cluded a strong post-trip review process, improvements in management's involvement
          in day-to-day operations, a high quality of operator training, and a high degree
          of professionalism by control room personnel.

                This section of the SALP report now includes' refueling and outage management (pre-
                  viously Category 2), which was previously rated as a separate functional area.                  {
                This SALP was based on monthly resident inspections and one team inspection cover-
                  ing the maintenance / modification activities conducted during the 7R refueling out-            :
                age. It also was based on augmented NRC coverage during Cycle 7 start-up and dur-
                  ing other outage transition periods.
                During routine power operations, the licensee maintained a professional environment
                  in the control room and assured that distractions to the opersting crews would be
                kept to a minimum. Operators rigorously controlled access ta'the control room
                proper.to restrict the number of non essential personnel ir, this area. Shift
                supervisors consistently maintained authority over activities and provided detailed
                turnover. briefings to the relief crews. Operating crews consistently demonstrated
                a detailed knowledge of plant design and procedural requirements associated with
                equipment operation. The approach to full power operation following the 7R re-
                fueling outage was deemed to be deliberate, conservative, and professional. Man-
                agement decisions to address a number of typical minor equipment problems were
l
I
                based upon safety considerations even if it meant slipping the schedule. Although
                frequent involvement by the Operations Manager; Director, Operations and Mainten-
                ance; and TMI Director were. apparent, the operators did not appear to be rushed
                to get the plant back on line.      Response to alarms and off-normal conditions was
                prompt and appropriate to the situation.
                Operator vigilance during steady-state and transient conditions was excellent.
                A number of minor transients-(Section II.D) resulted from equipment malfunctions                  i
                'and maintenance personnel errors.    Licensee middle management appropriately sensi-
                tized operators to the potential impact on the plant when the Integrated Control
                System'(ICS) manipulations or work was on going.      For all transients, control room
                operators responded alertly to prevent a plant trip / runback and quickly restored
                the plant to normal, steady-state operations. The event that resulted in exceeding
                the RCS technical specification limit for plant heat-up rate and some other minor
                events were due to poor communications, not poor vigilance. Overall, operators
                acted in a conservative manner with respect to nuclear safety.
                There were some misunderstandings during power operation and during the outage re-
                garding operator knowledge of plant status. One significant miscommunication oc-
                curred during simultaneous maintenance and operational use of Reactor Coolant Sys-
                tem (RCS) drain piping. The event resulted in a spill of radioactive water onto
                the reactor building (containment) floor. One LER on inoperable chlorine detectors
                resulted from a miscommunication on the status of the detectors. The licensee's
                self-review identified a problem in maintaining a knowledge of plant status during
                outages. Operating personnel had to coordinate and control a large number of
                diversified maintenance jobs and modification activities being performed in various
                plant areas. There was not an effective method of keeping track of all of these
                activities early in the outage.

                      Two senior reactor operator and five reactor operator candidates were administered
                      written and operational examinations and licenses were issued to all including one
                      RO candidate who required a retest. All candidates exhibited weaknesses during
                      the operating test portion of the examinations on the simulator in that they were
                      unable to identify the cause of various instrument failures in the Integrated Con-
                      trol System (ICS). While overall operator training is satisfactory, training man-
                      agement needs to pay closer attention to simulator transient response training.
                      However, as stated above, operator response to actual transients was good.
                      Overall, operators were well trained for all plant modifications installed during
                      the refueling outage. In addition to classroom training on major changes, the
                      operations department issued substantial training handouts which also were bene-
                      M clal to the support and management personnel who needed knowledge of facility
                      changes.
                      Upper and middle management attention to and involvement in plant operations were
                      evident. They continued to implement a number of positive measures described in
                      past SALP reports. Such involvement resulted in an enhancement to identify plant
                      problem areas. The most notable example of their conservative approach to safe
                      operation includd M.utting sun the plant to investigate the cause of the reactor
                      coolant pump problem before they exceeded any Technical Specification (TS) limits.
                      As further evidence of their involvement in this area, middle management instituted
                      a number of initiatives as described below. Plant housekeeping was good throughout
                      this SALP period as a rule.    Following the refueling outage, the quality of house-
                      keeping trended downward in areas where system modification work was in progress.
                      Housekeeping in the radiologically controlled areas as noted in the Radiological
                      Controls section of this report is good.
                      Middle management took a number of initiatives to further improve overall opera-
                      tional performance. Included in these initiatives was a program to cross-assign
                      extra shift supervisors (SS) among shifts in order to free up the most experienced
                      SS's for other support duties, such as simulator training. They also instituted
                      a plant component labeling system along with enhanced shift turnover notes in the
                      interest of efficiency. Further, upper management detailed operating personnel
                      to participate in INPO evaluations at other sites. Also, the licensee implemented
                      several administrative control initiatives to adequately log and further evaluate                                                  l
                      incidents having relatively minor significance. However, these actions were not
                      completely effective. Preliminary review by inspectors identified that related
                      guidance on such incidents was incomplete. The licensee implemented revised guid-                                                  {
                      ante at the end of the SALP period. The effectiveness of all of these measures
                      remained to be determined.
                      The overall planning of all the outage activities was effective due to good per-
                      formance in the areas of inter-departmental and contractor interfaces, routine
                      status meetings, radiological controls, as well as management attention and in-
                      volvement. The plant had four forced outages (Table II.C); two of these were for
                      maintenance to repair the No. I seal on the "D" reactor coolant pump (RCP). Each
                      unplanned outage required significant " impromptu" replanning of manpower resources,
                      vendor interfaces, training, as well as special testing, especially during weekends.
                                                                                                                                                        1

                    The results were that the licensee's overall planning and implementation of main-
                    tenance activities were well coordinated and effective. Management's involvement
                    in assuring successful completion of each outage was noteworthy. Considerable
                    resources were expended on determining the cause of the "D" RCP seal problem but
                    no definitive root cause was determined.
                    Inspections noted improved performance in the area of adhering to operational pro-
                    cedures. This is in contrast to administrative control procedure adherence. The
                    licensee's Quality Assurance Department similarly noted these results, but they
                    also identified a continuing problem in the area of adherence to administrative
                    controls (see Section IV.G). Inspectors noted proper alignment of systems in ac-
                    cordance with operational procedures. Despite weaknesses stated in the last SALP
                    report, the licensee's independent verification program continued to be effectively
                    implemented to assure proper safety system alignments. However, as noted below,
                    some discrepancies in the area of procedure adequacy continued to challenge opera-
                    tors to comply with procedures.
                    In general, inspections confirmed the adequacy of procedures, especially with re-
                    spect to safety system alignments. The licensee made improvements in the quality
                    of emergency operating procedures (EOP's). However, inspectors continued to note
                    individual step inadequacies in some of the relatively frequently used procedures.
                    One problem occurred in that two valves had been inadvertently omitted from a valve
                    lineup checklist for the emergency diesel generators. Other minor procedural de-
                    ficiencies caused operator confusion in some instances and had the potential to
                    cause procedural non-adherence. None of these examples within this functional area
                    resulted in an event of major safety significance.      However, such discrepancies
                    indicated that the biennial procedure review process, was not completely effective
                    in preventing procedure problems.
                    In summary, operator professionalism, competence, and vigilance were significant
                    operational strengths and operator training was conducive to this strong overall
                    performance. There was improved performance in adhering to the operational
                    procedures, but the quality of certain administrative control procedures needs      i
                    to be improved. Middle management control of plant operations and outage            )
                    activities was very good. All levels of management were involved in the conduct      1
                    of daily operations. Middle and upper management acknowledged areas where
                    improvements were needed. In some cases, however, management response was slow
                    in implementing corrective actions to improve performance in these areas.
                    Operator performance continued to significantly contribute to the overall

          IV.B Radiological Controls
          IV.B.1      Analysis
        The last SALP report rated this area as Category 1. Concerns during that period
        were limited to occasional improper posting of high radiation areas as well as
        several deficiencies in performing surveys in connection with some radwaste opera-
        tions.
        Two specialist inspections were conducted in this area during the current SALP
        period. In addition, there were routine reviews by the resident inspectors.
!        Performance in the areas of concern identified during the last period has improved.
        Performance in radiological controls, in general, has maintained the same level
        of high quality as that observed during the last SALP period. Management at all
        levels remains involved in the daily activities on site and is also constantly
        apprised of the details of on going and future radiologically significant activi-
        ties. The responsibilities of the tinagers and supervisors are clearly defined
        and are well understood by the staff. Management at all levels also remains re-
        sponsive to concerns expressed by the staff or by the NRC. As an example, a review
        of the issues raised in incident reports and concerns raised by workers shows that
        the radiological engineers consistently study these issues, make recommendations,
        and initiate corrective action, if appropriate. Audits of the site radiological
        controls program, both internal and corporate, are performed periodically and the
        findings are evaluated and acted upon. One concern in this area was the inadequate
        planning of scaffolding erection during the last outage. The result was unneces-
        sary radiation exposure. Management's responsiveness is exemplified by the fact
        that this deficiency was recognized and plans were made to improve performance in
        the next outage.
        Radiation exposure and access control by radiation work permit remains effective
        and the job descriptions and access requirements in the permits are generally good.
        Surveys are usually of high quality and are timely as is the air sampling program.
        Personnel contamination control is effective and well documented. Although surveys
        are routinely performed on schedule, a minor concern in this area is that new sur-          ;
        veys are sometimes not posted in place of the expired surveys in all the areas.              l
l        Surveys and measuring instruments are routinely calibrated on schedule. Support            !
        programs, such as the respirator maintenance facility, personnel dosimetry, and              I
        instrument service and calibration facility, are effective and well run by com-              )
        petent professionals.
                                                                                                    ]
        The training programs for radiation workers and for the health physics technicians
        are good. The staff in charge of these programs are competent and expe-ienced in
        plant operations. Based upon the staff's limited observations, we cons der the
        health physics staff to be well qualified and well trained.
        Performance in the area of ALARA continues to be goud. Outage planning 15 still
        being performed in a satisfactory manner and ALARA oversight duris.3 njcr jobs is            i

                are on going. These efforts include system and area decontamination, a cobalt
.
                reduction program, mock-up training, and improved procedures, such as those for
l                eddy current inspections, based on lessons learned from previous outages. Despite
l.              these efforts, however, the dose goal (120 man rem) was exceeded during the last
L              outage (157 man-rem). The reasons appear to be a combination of planning
l'              problems associated with scaffolding erection, hot transient working conditions,
I              and unexpectedly high minor maintenance work,                    Licensee's responsiveness to
l                identified problems is exemplified by a demonstrated awareness of the problem
i                (scaffolding erection planning) and its causes and the formulation of solutions
l              to prevent recurrence. Solutions include the use of permanent or semi permanent
                scaffolding and a more detailed mapping of the locations of items such as valves
                and welds that may require maintenance and inspection in the future. Locating
                such items, many of which are in relatively high dose rate areas, has contributed
                significantly to the cumulative exposure for the last outage. The cumulative
                exposure, though higher than the estimate, is indicative of good performance.
                Three inspections of the licensee's solid radioactive waste (radwaste) and trans-
                portation program were performed, including processing, preparation, packaging,
                shipping, quality controls, and audits. Two problems occurred with radwaste ship-
                ment manifests associated with TMI-2 decontamination. Licensee corrective actions
                to correct the problem were prompt and appeared to be of sufficient depth to pre-
                vent recurrence. Additionally, the training program for personnel in this area
                was found to be strong. Despite the problems, the licensee is maintaining an ef-
                fective program in this area.                                                                                                  ,
                Three inspections of the licensee's effluent controls were performed during the
                assessment period. Effluent control procedures were very detailed and accurate.
                The licensee properly implemented its Off-Site Dose Calculation Manual (ODCM).
                The dose calculation methods were found to be comprehensive and adequate to accomp-
                lish their purpose. The licensee's dose calculations were performed in accordance
  .            with the procedures that implement the methodology described in the ODCM. Release                                              I
                permits were properly completed and accurate with respect to dose calculations.                                                ]
                Good agreement was obtained between expected and actual responses of selected ef-
                fluent monitors, as confirmed by the inspector's calculations. Operability checks
                and calibrations were performed as required. The licensee maintains good control
                over deficiencies identified during calibrations and tests. The licensee is main-
              ~taining an excellent program in this area.
                Two inspections of the licensee's radiological environmental monitoring program
                were conducted including Quality Assurance / Quality Control (QA/QC) of the analy-
                tical laboratory, comparison of the collocated thermoluminescent (TLD) monitoring
                results and meteorological monitoring program. QA/AC of the analytical laboratory
                is well maintained. The monitoring results of the licensee's TLD's collocated with
                NRC's are generally in agreement. Calibration and preventive maintenance of the
                meteorological instrumentation was found to be adequate. The annual environmental
                monitoring report was reviewed and found the licensee performed all aspects (samp-
                ling, analytical sensitivities, reporting schedules, and inter-laboratory compari-
                son) as required. The licensee is maintaining an effective program in this area.

                An inspection was conducted using the NRC's mobile laboratory during the last
                quarter of the assessment period. The licensee's performance with respect to ac-
              .tual samples during the inspection was good with the exception of detecting radio-
                activity in a charcoal cartridge used to sample iodine effluent from the main con-
              ' denser exhaust. Because of an erroneous essumption regarding distribution of
                iodine within the cartridge, the licensee's analysis indicated an' activity of 30%
                lower than that measured by NRC.    This problem was initially identified in 1986,
                During the NRC mobile laboratory analysis in 1988, the staff determined that the
                iodine was deposited uniformly.throughout tne' cartridge resulting in the analysis
                error, and also indicating excessive moisture in the sample stream. The licensee
                has now committed to resolve the moisture problem and correct past effluent reports.
                Management response to this issue was very slow indicating that the original issue
                had not been elevated to the proper level of management attention. The public
                health consequences of this error was very small. However, the length of time
                taken to resolve the issue indicates occasional lack of attention to NRC inspection
                findings.
                Summary
                In. summary, the radiological controls program remains effective in controlling
                access to radiologically controlled spaces, controlled areas are posted in accord-
              - ance with applicable requirements, and good housekeeping is generally maintained
                in the controlled areas.    Planning and control of jobs in radiological areas is
    '
                also good, and_ efforts.to minimize individual and cumulative exposure appears to                  .
;            . be effective. Training of radiation workers and of health physics technicians is
                good. Support programs such as dosimetry and respiratory protection are well
                managed and technically current. The overall assessment is that the radiological                  -
                control program onsite is a high quality program.                                                  ;

                IV.C Maintenance / Surveillance
                IV.C.1    Analysis
                During the last SALP period, no major maintenance programmatic problems were evi-
                dent and the licensee's performance was judged to be a positive influence on opera-                  4
              .tions. The surveillance program was well managed. The implementation of the in-                        '
              . service inspection (ISI)., as well as inservice testing (IST) of equipment, ensuring
                operability of safety-related equipment, was adequate and effective. A Category
                1 rating was assigned to both the maintenance and surveillance areas.

                During this assessment, the NRC staff combined the maintenance and surveillance                      I
                areas into an equipment operability perspective. The overall assessment included
                routine inspections by the resident inspectors, specialist inspections by region-                  1
                based inspectors, as well as a special team inspection, covering major 7R mainten-
                ance/ refueling outage sctivities.

          Maintenance Organization and Planning
          The licensee conducted a self-assessment and changed the maintenance organization      "
          stru'cture, emphasizing three areas: materiel assessment, corrective / preventive
          maintenance, and planning and scheduling. The new organization had qualified and
          experienced people in these areas and there were indications that this change would
          be instrumental in improving performance. Examples of the effectiveness of these
,
          changes included successful completion of the 7R outage ahead of schedule, compu-
          terizing work packages, strengthening of motor-operated valve actuator testing
          programs, implementation of scientific event review process, development of a mai-
          ntenance plan to further improve materiel conditions of the plant. Most notable,
          the maintenance organization initiated a new reliability centered maintenance (RCM)
          program, which involved systematic assessment of systems, emphasizing functional
          reliability, current preventive maintenance measures, and then upgrades as neces-
          sary to enhance equipment reliability.
          Despite the overall good planning and outage management efforts, several shortcom-
          ings in specific job planning and implementation for routine and outage work ex-
          isted. The licensee had a total of seven violations during this assessment, with
          five violations attributed to this functional area. The problems were generally
          reflective of poor specific job planning, inadequacies in maintenance / surveillance
          procedures, and failure to follow administrative procedures. With respect to
          specific job planning, a significant example was the installation of a wrong ex-
        pansion joint in the reactor building emergency cooling water system. In addition
          to this, there were other examples of inadequate maintenance program implementation
        as addressed below.
        Maintenance Implementation
                                                                                              '
        With respect to maintenance procedure adequacy, the inspectors noted that a sub-
        stantial number of preventive and corrective maintenance procedures were estab-
        lished. Overall, these procedures were adequate. However, pump work was performed
        using a generic maintenance procedure and a substantial rework effort on one of
        the pumps resulted from the failure to incorporate appropriate vendor guidance into
        the procedure.
        With respect to properly following administrative controls, there was overall
        satisfactory performance considering the number of measures that need to be im-
        plemented for substantial maintenance / modification work packages. However, the
        examples of nonadherence were significant. For example, two problems involved
        licensee failures to properly incorporate vendor-supplied information into specific
        work instructions. There were also examples of incomplete job tickets and exces-
        sive delays in making return to service signoffs, some up to three months. The
        licensee recognized the administrative controls problem and they were to address
        it by their administrative compliance task force (see Section IV.G). However,
        these examples were also generally reflective of a lack of awareaess by licensee
        and contractor personnel on the numerous administrative measures that existed in
        this functional area.

                                                                  Overall, the materiel condition of the plant based upon routine plant tours by.the
                                                                    inspectors remained generally good. Despite a licensee program in this functional
                                                                  area,.the inspectors noted some materiel deficiencies, such as loose conduits,
                                                                  connections, supports, bolts, and missing clamps. This reflects a lack of atten-
                                                                  tion to detail by licensee personnel in identifying minor material deficiencies
                                                                  during routine and special plant tours. The licensee was responsive by developing
                                                                  a new procedure to further improve their current program. However, its effective-                                  i
                                                                  ness remained to be determined at the end of the SALP period.                                                      i
                                                                  Maintenance Activity Interface
                                                                  During several maintenance activities, the inspectors noted substantial interfacing
                                                                  among the Quality Assurance / Quality Control (QA/QC), Plant Maintenance, Engineering
                                                                  and Operations groups. . However, inspectors noted some weaknesses. Maintenance
                                                                  personnel caused a number of transients which challenged operators. In addition
                                                                  to personnel error, the root causes were similar to the causes of the examples
                                                                  noted above. In the area of receipt inspection, two different kinds of injectors
                                                                  and thermocouple as well as the jacket cooling water pump motor having the same
                                                                  part numbers, were received, accepted, and installed on the emergency diesels
                                                                  without adequate review by the responsible work groups. In one case, a diesel
                                                                  generator inoperability resulted. A receipt inspection error contributed to tne
                                                                  installation. The licensee planned to re-evaluate their receipt inspection program,
                                                                  as well as other interface deficiencies, to prevent recurrence.
                                                                  The major plant modifications were installed by Maintenance, Construction and
                                                                  Facilities. During the 7R outage, some of the major modifications, such as me-
                                                                  chanical' cleaning and tube plugging of main steam generators, were well managed
                                                                  and completed in a safe manner on or ahead of schedule with successful post-modi-
                                                                  fication testing.                                  In general, surveillance /special testing compleinented mainten-

                                                                  Overall, the licensee continued to imp Nment a well-established surveillance pro-

                                                                  Even though various groups were involved, they were, in general, well coordinated
                                                                  and the interfaces properly defined. A Not.cle example was the licensee's reactor
                                                                  building local leak rate testing.                                  In general, the surveillance procedures ade-
                                                                  quately addressed the acceptasce criteria, as well as follow-up actions, on failed
                                                                  surveillance. The test methods and procedures were technically sound and con-
                                                                  sistent with accepted industry practice. The procedures were clear, detailed, and
                                                                  provided good administrative control. The personnel performing the tests were well
                                                                  trained and qualified. During surveillance activities, the inspectors noted that
                                                                  the communication among various groups was clear and each procedure step was fol-
                                                                  lowed and signed off by designated per;onnel.

                                          tion before the 7R refueling outage, the licensee experimented with morpholine for
                                          pH and oxygen control and the results were positive, justifying a shift to that
                                          type of chemistry control.          The licensee also upgraded the chemistry laboratory
                                          by installing additional equipment. The licensee effectively controlled secondary
                                          water chei.Mstry and provided initiatives to improve performance.
                                          Relative to the last SALp assessment, the nonradiological chemistry control                ,
                                          program remained constant.          During an inspection of the 1icensee's nonradio-      j
                                          logical chemistry control program, standard solutions prepared by Brookhaven              l
                                          National Laboratory for the NRC were submitted to the licensee for analysis              {
                                          using the licensee's routine methods and equipment. Licensee performance on                j
                                          the standards was acceptable. Some minor problems were identified in the areas            l
                                          of instrument calibration. A recent inspection determined that this problem                j
                                          has been resolved.                                                                        l

              In addition to maintaining emergency preparedness effectiveness, the licensee has
              undertaken a number of improvement activities in response to NRC and GPU initi-
              atives. In response to an NRC concern, the Technical Support Center (TSC) engi-
              neering staff number has been increased and training is being upgraded. Five en-
              gineers and a senior reactor operator have been added to the staff. In addition,
              a TSC Engineer's. Handbook has been developed. TSC engineers have received problem
              solving training using this handbook plus training in Abnormal Transient Operating
              Guides.                                                        In order to significantly reduce the probability of a recurrence of the
              May 1987 communication system failure (noted in the 1987 SALP report), GPU cnd the
              Pennsylvania Emergency Management Agency (PEMA) have installed additional communi-
              cation systems including an additional land line and radios for PEMA.
            . Senior management attention to emergency preparedness activities is evident by the
              interfaces with outside organizations and response to issues. 'The Director of
              GPU's Division of Environmental and Radiological Controls devotes much of his time
              to emergency preparedness activities and regularly updates the GPU Nuclear President-
            -on emergency preparedness matters or responds to his requests in this area.
              In summary, the licensee has committed sufficient resources to emergency prepared-
              ness and has demonstrated response to GPU and NRC identified concerns. Technical
              issues have been resolved. Upper management has become routinely involved in
              emergency preparedness activities. There are no off-site problems. Exercise per-

'
              During the previous assessment period, the licensee's performance was rated as a
              Category 1, based on a very effective security program. No major regulatory issues
              were identified by either region-based or resident inspectors.
              During this assessment period, there were two routine unannounced security inspec-
              tions performed by region-based inspectors. Routine inspections by the resident
              inspectors continued through the period. There was one licensee-identified viola-
              tion during this assessment period for which the licensee took timely and effective
              action to correct the problem, identify the root cause and strengthen procedures
              to prevent recurrence.                                                                The self-identification of that violation and the lack of
              any NRC-identified violations during this and the previous assessment period are                                                                          i
              indicative of the licensee's commitment to implement an effective security program.
              The licensee consolidated implementation of the Unit 1 and Unit 2 security program
              during this assessment period. Due to some unique circumstances at TMI, implemen-
              tation of certain aspects of the physical security program were different between

                                Unit I and Unit 2. The NRC completed its review of the licensee's request to unify
                                the program, as well as the licensee's submittals in response to the Miscellaneous
                              Amendments and Search Requirements rulemaking and the staff's Regulatory Effective-
                                ness Review. This review was complex and required a number of meetings, site
                                visits and conference calls. The NRC received good cooperation from licensee per-
                                sonnel and was able to issue a favorable Safety Evaluation Report (SER) in Septem-
                              ber 1988. Within a month, all procedures that implement the revised Plan were also
                                revised by the licensee.                        These modifications were accomplished without any adverse
                                impact on the effectiveness of the program and is evidence of effective planning
                              and management, as well as a sound program.
                              Corporate security management continued to be actively involved in all site secur-
                                ity program matters. This involvement included site visits by the corporate staff
                              to provide assistance, program appraisals, and direct support in the budgeting and
                              planning processes affecting program modifications and upgrades. Site and corpor-
                              ate senior security management personnel also remained active in the Region I Nuc-
                                lear Security Association and other organizations engaged in nuclear plant security
                              matters.                          This demonstrates program support from upper level management.
                              The NRC-required annual audit of the security program, performed by the licensee's                                    ,
                              quality assurance group, was comprehensive in scope and depth. Contributing to
                                                                                                                                                    '
                              the effectiveness of audits were a thorough understanding and appreciation for
                              nuclear plant security objectives by the audit team members. In addition to the
                              NRC-required audit, the licensee also continued to conduct self-assessments of the
                              program utilizing experienced security management personnel from corporate head-
                              quarters and the licensee's Oyster Creek plant.
                              Corrective actions on findings and recommendations identified during audits and
                              self-assessments were prompt and effective with adequate follow-up to ensure their
                              proper implementation. The NRC believes that the comprehensive quality assurance
                              audits and the self assessments are major contributing factors in the licensee's
                            excellent enforcement history and are indicative of the licensee's desire to im-
                            plement an effective security program. Further evidence of this is the licensee's
                            continued effective implementation of program enhancements that were initiated
                            during the previous assessment period.
                            The programmatic problem with source training documents, which was addressed in
                              the previous SALP period, was subsequently determined by the NRC to be inconse-
                            quential once the transition from hard copy documents to microfiche files was com-
                            pleted. During this assessment period, records retrieval was adequate.
                            The licensee submitted one security event report in accordance with 10 CFR 73.71
                            during this assessment period. That event involved the control of Safeguards In-

                            The event was properly reported to the NRC and the documentation was sufficiently
                            comprehensive to permit NRC analysis without the need for additional information.
                            Recordable events were also found to be consistent with NRC guidance. Review of
                            the licensee's event reportiog procedures found them to be consistent with regula-
                            tory requirements and implemented by knowledgeable personnel. This is further
                            evidence of the implementation of an effective security program.

            The licensee has documented the process for engineering configuration management
            and has established programs for improving design basis documents, conducting
            safety system functional inspections, and improving as-built drawings to reflect
            plant conditions. These are good initiatives; their effectiveness has yet to be
            assessed by the NRC.
          The Computer Assisted Record and Information Retrieval System provides accurate
            tracking and documentation of plant configuration; however, NRC inspectors found
            that using the system to construct the current configuration of a system is very
            time consuming.
          The licensee is effectively using architect engineers (AE) to supplement the staff.
          A prime AE has been selected for each of the plants and a wide spectrum of engi-
          neering expertise is available on short notice to work with the licensee's staff.
          The liconsee also took the initiative to make a number of significant capital im-
          provements not required by NRC; namely, the reactor building closed circuit tele-
          vision and the plant communications tie switch for simulator use during emergency
          drills.
          The licensee submitted a Level I PRA in December 1987 for the staff's information.
          The PRA is a state-of-the-art document and includes external events and human per-
          formance considerations. The staff is performing an abbreviated review of the PRA
          to assess the level of confidence that might be placed on it should it be refer-
          enced in the future licensing action decisions. The licensee has initiated an
          internal program to assess, on a cost-benefit basis, possible design, procedure
          and policy changes to address various risk contributors disclosed by the PRA.            Some
          modifications, including those to the instrument air system, have already been
          initiated due, in part, to the PRA results.
          Licensee upper management strongly supports participation in industry, owners
          groups, and professional societies. This was evident by individual participation
          and financial support to INPO and the number of people representing GPUN on the
          owners and other industry groups.
          Support of Operations
          During this assessment period, the licensee was effective in resolving emerging
          technical problems. Self-identification and resolution of the pressurizer vent
          valve environmental qualifications issue were noteworthy. lhe review of the valve
          function and the justification for continued operation with the valve not environ-
          mentally qualified was thorough and complete. Also, the identification of the
          Borated Water Storage Tank (BWST) vortexing issue was resolved in a timely and
          adequate manner. Resolution of a potential problem with the net positive suction
          head (NPSH) available to the high pressure injection (HPI) pumps in the recircula-
          tion mode was also thorough. These actions reflected good corporate engineering
          support. However, some other activities indicated that improvement can still be
          made in engineering support. For example, the load calculation for assuring the
          adequacy of the diesel generator was not well supported. Also, the emergency
          feedwater (EFW) system upgrade was not sufficiently followed through in the non-
          safety-related area.

                                    Engineering support for low power physics testing was well coordinated and resulted
                                    in a trouble free start-up after the 7R refueling. The nuclear engineering staff
                                    provided good support to the operations staff during_these activities.
                                    The licensee's shift technical advisors report to the systems engineering depart-
                                    ment of Technical Functions Division. This system appears effective in providing
                                    an independent technical overview of the plant operations by the Technical Func-
                                    tions Division staff knowing the plant status on a day-to-day basis and being ready.
                                    to provide assistance at short notice. This was evidenced by the division staff's    I
                                    readiness to provide assistance for the problem of biofouling in the heat exchan-
                                    gers at TMI before the operating staff made a request'for evaluation.
                                    Previous fire protection issues were resolved during this period. The licensee's
l                                  engineering analysis was thorough. It included in plant testing to validate the
                                    air flow / temperature models and demonstrated a significant reduction in the core
                                  melt frequency estimated in the TMI-1 PRA.
i
                                  Outage Activities
                                    Improvement in engineering support of outage activities was evidenced by successful
                                  and early completion of cycle 7R outage. Outage activities were well' controlled
                                  and few problems occurred in plant restart, demonstrating the quality of the work
                                  performed. The licensee's new policy of completing the design, engineering, and
                                    supporting technical evaluations for modifications and other associated work before
                                  the start of the outage contributed to this success. This is in sharp contrast
                                  to the licensee's previous practice of engineering, design and erection of modifi-
                                  cations going concurrently throughout the outage. Also, changes in administrative
                                  controls to improve the turnover of modifications from construction to operations
                                  were made during the assessment period.
                                  Technical support of. post modification activities needs greater attention as shown
                                  by the following instances. Opportunities to verify functional acceptability of
                                  the new post accident monitoring systems were missed. For example, functional
                                  checks of the Rector Coolant Inventory Tracking System (RCITS) level indicators
                                  during RCS fill were not routinely planned. Also, during power decreases and in-
                                  creases following 7R, operation of the NI-11/12 full range nuclear instrumentation    1
                                  was not functionally verified.
                                  The quality of the information submitted in support of the 7R refueling and the
                                  evaluations to support raising the licensed core power level were of high quality
                                  and made requests for additional information by the staff unnecessary. The com-
                                  pleteness of the submittals allowed issuance of the required amendments several
                                  weeks early.
                                  Response to NRC Initiatives
                                  Examhles of response to NRC initiatives included the Integrated Control System /Non-
                                  Nuclear Instrumentation (ICS/NNI) power supply modifications and ICS upgrades with
                                  incorporation of the Smart Automatic Selector Switch (SASS) modifications for ICS

                                          control parameters. Significant progress was made in the closeout of NRC inspec-
                                      ' tion items during this assessment period. The licensee provided good support of
                                          an NRC review of several Safety Issues Management System (SIMS) issues during this
                                          SALP period.
l                                          During this period, the staff completed its review of the Babcock &.Wilcox Dwners
                                          Group (BWOG) generic design to fulfill the Anticipated Transient Without Scram
                                          (ATWS) rule requirements in accordance with 10 CFR 50.62. Contrary to guidance
                                          provided by the staff, the licensee proposed design failed to address a power sup-
                                          ply separation issue and resubmittal will be required. The staff also has concerns
                                          regarding the implementation schedule for these design changes.
                                          During the SALP period, the licensee was responsive to the previous SALP Board
                                          recommendation by briefing the NRC staff on the status of their technical support
                                          self-assessment. They conducted these briefings on-two occasions during 1988; the
                                          second briefing was more definitive in terms of specifying short-term corrective
                                          actions to improve engineering support. Implementation of these corrective actions 4
                                          was in progress at the end of the SALP period. From these briefings, it was un-    I
                                          clear which of these corrective actions would be preceduralized or become formal
                                          matters of corporate policy. Effectiveness of these measures also remained to be
                                          evaluated.
                                          Staffing and Training
                                          The licensee has maintained a stable work force in the engineering organization.
                                          The majority of the engineers and other technical personnel have been with the
                                          licensee for an extended period of time and are degreed professionals. The licen-
                                          see has a comprehensive training program for entry level engineers and supports
                                          continuing expansion of technical knowledge by thorough post graduate education
                                          and attendance in technical meetings and seminars by the technical staff.
                                          Licensee efforts to ensure that personnel are appropriately trained on new systems,
                                          modified systems and other changes to plant systems are effective. NRC staff re-
                                          view of operations training handouts revealed a comprehensive and effective means
                                          for informing support personnel and management, as well as operators, of these
                                          changes.
                                          Summary
                                          The licensee's performance in the area of engineering and technical support is
                                          improving. This is particularly true in the support of outage activities; however,
                                          in other areas such as support of operations and management controls, additional
                                          time is required to confirm the effectiveness of licensee initiatives.

              IV.G Safety Assessment / Quality Verification
              IV.G.1    Analysis
              In previous SALP reports, Assurance of Quality and Licensing Activities were
            evaluated in separate sections of the report. This new section (Safety Assess-
            ment / Quality Verification) has been created to consolidate those two sections and
            to encompass activities such as safety reviews, responses to NRC generated initi-
            atives and to provide a broad assessment of the licensee's ability to identify and
            correct problems related to nuclear safety. In assessing this area, the SALP Board
            considered attributes which are likely to be key contributors in assuring nuclear
            safety and verification of quality in operation of the plant.                                                                                          Implementation of
            management goals, planning of both' routine and infrequent activities, worker at-
            titudes, management involvement and training effectiveness are examples of these
            attributes.
            In the previous SALP, Assurance of Quality and Licensing Activities both received
            category 2 ratings. The SALP report identified as strengths a strong modification                                                                                            .
            control program, training effectiveness, a vigorous QA program and substantial                                                                                              i
            upper management involvement in site and licensing activities. Weaknesses included
            procedure compliance, inconsistencies in the conduct of safety reviews of procedure
            changes, engineering support and escalation of issues identified by the QA program.
            Licensee performance in the areas of fire protection and equipment qualification
            were also identified as areas requiring improvement.
            During the assessment period the NRC observed activities directed towards correct-
            ing previously noted problem areas and achieving agreement with the NRC to resolve
            these areas. Engineering support issues have been discussed in Section IV.F of
            this report.                      The quality of procedures and improvements in the safety review pro-
            cess are discussed Lwlow. The licensee also maintained an effective level of ac-
            tivity in the organizai.f onal components involved in identifying problems and veri-
            fying quality including Quality Assurance oversight, Independent On-Site Safety
            Review Group (IOSRG) reviews and the corporate Nuclear Safety and Compliance Com-
            mittee (NSCC) audits. The licensee took substantial initiatives for self-assessing
            performance in certain functional areas.                          Personnel were capable of performing
            these self-reviews in an objective manner because of their qualifications or spe-
            cial training.                      Results indicated that these reviews were objective. The most
            noteworthy methodology was the Human Performance Evaluation System (HPES).                                                                                            Licen-
            see management showed support for this area by committing resources to these ef-
            forts including special training. The Safety Issues Assessment Program (SIAP) was
            further evidence of management commitment to this effort and it represented an
            attempt to organize and prioritize important safety and/or regulatory issues. This
            prioritization was important in light of the numerous findings of the various re-
          . view groups that were site or corporate based.                                      The licensee also submitted a Level
            I PRA for the staff's information during this period (See Section IV.F).
            During the assessment period, 59 formal licensing actions were under review. These                                                                                              )
            actions included license amendments, exemption requests, NUREG-0737 action plan                                                                                                1
            items, relief requests and inspection confirmatory issues. Action had been com-
            pleted on 34 of these actions and 25 actions remained open as of the end of the                                                                                              {

                      period. Many of these actions involved complex issues such as increasing the en-
                        richment of the uranium fuel, reactor refueling, increasing the authorized reactor
                      power level, accident monitoring instrumentation (Regulatory Guide 1.97), and fire
                      protection.                      Fifteen amendments were issued to the TMI-1 Facility Operating License
  ,
                      during this period.                                                            In addition, the NRC issued seven Generic Letters and six.
                      Bulletins that required licensee action and response during this period.
                      During this SALP period, the quality of formal submittals with regard to licensing
                      issues remained excellent and the licensee's cooperation in resolving these issues
                    was exemplary.
                    Quality Assurance Department (QAD) oversight activities continued to be a valuable
                      asset to the-licensee's organization. Audits continued to be highly technical,
                    detailed, thorough, and reflect innovative techniques. Inspections noted that the
                  ' Quality Assurance Monitoring Reports (QAMR's) reflected an excellent process of
                    QAD documenting and verifying program implementation across all functional areas
                      of plant. activities. The QA inspectors provided detailed references, procedure
                      requirements, and verification results. This documentation was sufficient for a
                      knowledgeable reviewer to understand the basis on the QA inspectors' results.
                      Further,-QMAR's and Quality Deficiency Reports (QDR's) were sufficient vehicles
                      to trend procedure adherence performance for this facility.
                    The Operations Quality Assurance (0QA) Quarterly Trend Review identified deficien-
                    cies through the use of Quality Assurance Shift Monitors, who look at back shift
                    activities on a six-week cycle.                                                                In addition, the trend review appeared to be ef-
                      fective in that QAD conducted an overview and comparison of individual QA findings.
                    They issued additional quality assurance action items for repetitive concerns iden-
                    ti fi ed. For example, the October 11, 1988, 00A Quarterly Trend Review documented
                    eight areas where repeated QA findings indicated possible performance trends. This
                    overview function was effective in that a preventive philosophy was implemented.
                    The NRC reviewed several of the licensee's 10 CFR 50.59 evaluations for plant modi-
                      fications as well as changes to procedures and a special test for addition of mor-
                    pholine to the feedwater system. The evaluations for hardwarc changes were well-
                    done and typically supported by detailed technical reports or Safety Evaluations.
                    The 50.59 review for the morpholine test included r consultant report providing
                    extensive test results for morpholine exposure to various materials and data based
                    on previous use of morpholine in other plants. In general, licensee personnel do
                    a thorough job of evaluating changes or tests as provided by 10 CFR 50.59.
              . _ On the.other hand, 50.59 reviews for administrative and operating procedure changes
                    were sometimes found to be lacking in thoroughness, depth and documentation. The
                    GPUN procedure for these reviews provides for an initial screening to determine
                      if a more detailed evaluation using the 50.59 criteria is required.                                                                                                        In several
I                  cases involving procedure changes, the documentation did not clearly document the
                    basis for the reviewers conclusions. The staff believes additional improvements
                    are warranted in the reviews associated with procedure revisions.

          The staff notes that the licensee made progress in improving the corporate 5 fety
          reviewprocessduringthis~feriod. However, the manner in which the licen ee is
          implementing this procedure at the TMI site has one remaining open issue o be
          resolved with the staff. Implementation of the revised corporate procej ures atk
          TMI-I did not occur until after the end of the period; therefore, an assessment
          of resultant improvements at the site could not be made. Also, TMI ivision Draft
          Procedure was not in accordance with the corporate policy for the      fety Review
          Process. The licensee is also participating in a cooperative eff rt between the
          NRC and the Nuclear Utility Management and Resources Council (N . ARC) to develop
          uniform industry guidance relating to the safety review proces . In summary, the        i
          licensee has improved the quality of safety reviews in most      ses and is continuing
          to pursue improvements in this area.
          Although the attitude of management at all levels has remained positive and visible,
          a number of events occurred during this period (see gection IV. A of this report)
          that demonstrate implementation problems at the wayking level. Common causes that
          emerge are procedural inadequacies and lack of a'wa'rene)/s and attention to detail.
          For example, the decay heat removal flow path was inadvertently interrupted
          causing core heatup due to an instrument techrytcian performing one step of a
          surveillance procedure out of order. The license s human performance evaluation
          report on the event concluded that the techni        became distracted by an
        , ambiguity in the procedure, stopped to conf        th other technicians, then
          resumed following the procedure but at th        ng step. Other procedural step
          inadequacies continued to exist. A numb          significant problems resulted
        because of weak or inadequate procedur        described in the other functional
          areas. The biennial review process w        t completely effective in producing a
          steady improvement in procedures ov g , because of high frequency requirements
        and strained resources.    However,    actions noted continued improvement to
          the Emergency Operating Procedures    JP's). Licensee management, up to and
          including the Chairman of the Boar , is also aware of these problems via their
        own self-assessment committees in uding the NSCC.
        The staff has also noted a few cases where initial assessments of plant event
        safety significance and repor ability of plant events by the licensee have been
        incorrect and not initially entered in the operator's logs.      For example, problems
        that occurred on Jung 19, 988 during Low Pressure Injection surveillance testing
        were not entered in thq perators logs until they were later determined to be re-
        portable. It was de)(erinined, af ter studying the data, that two TS limits had been
        violated. In the pfevious SALP report, we stated that the licensee should initiate
        a program to evalpate less significant problems (i.e., those below the threshold
        of requiring a JAant Incident Report (PIR) or Licensee Event Report (LER)). The
        licensee has s nce initiated a progrmn to highlight and review such events. The
        staff will c tinue to monitor the quality of critiques, post-trip evaluations,            4

                            own self-assessment committees including the NSCC.
                            The staff has also noted a few cases where licensee initial assessments of the
                            safety significance of plant events have been incomplete. For example, prob-
                            lems that occurred on June 19, 1988 during Low Pressure Injection surveillance
                            testing were not entered in the operators logs until they were later determined

                            see Event Report (LER)). The licensee has since initiated a program to high-
                            light and review such events. The staff will continue to monitor the quality
                            of critiques, post-trip evaluations, event investigation and resultant correc-
                            tive actions. Overall, the staff considers that progress is being made in this

                                                  to their detailed, well-wrfTten event descriptions and root cause analyses As

                                                  condition findings during this SALP period. Established pro am/ review groups
                                                  continued to do an outstanding job of identifying problems,/nost notably the Qual-

            The quality of the licensee's LER's continued to be high during this period due
            to-their detailed, well written' event descriptions and root cause analyses. As
            noted elsewhere in this report, the number of events requiring LER's dropped from
            ten.last period to six this period and there was only one unplanned reactor trip
            during this 14 month period.
            In summary,- the'11censee has effective programs in place of assessing nuclear
            safety and verifying quality. A number of initiatives have been taken to en-        -
            hance performance in this area and the personnel involved are skilled and well-
            trained. Established review groups, mostly notably the Quality Assurance De-
            partment, have continued to do an adequate job of identifying problems. How-
            ever,' implementation of corrective action in some cases has failed to correct
            the problems. One'such example noted in this report is the thoroughness of
            safety reviews associated with procedure revisions, which' ultimately has had a
            detrimental effect on procedure quality. The quality of some procedures
            coupled with worker inattentiveness to details have led to a small number of
            -operational errors during this assessment period.

l                Table 2 reflected a summary of the enforcement action taken by the NRC staff for
l
'
                  TMI-1.. The description of the violations are also provided.

l
                  Additionally, two violations issued to Unit 2 in the radwaste area are discussed
                  in the analysis section of the Radiological Controls area.
                  On August 24, 1988, the NRC staff conducted one enforcement conference (No. 50-
                  289/86-06) during this period, dealing with apparent violations in the area of                              i
                  environmental qualification of safety-related equipment for items found outside
                  this.SALP period. As a result of this review, the. NRC staff issued a Notice of
''
                  Violation, dated December 29, 1988, with multiple examples of failure to comply
                  with 10 CFR 50.49. At the end of the SALP period, the licensee was preparing a
                  response.
I
                  C.      Licensee Event Reports / Analysis
                  Table 3 reflected a summary of Licensee Event Reports (LER's) submitted during the
                  SALP period.
                  LER's adequately described events, including contributing component or system
                  failures and significant corrective actions.      The reports were thorough, detailed,
i
                  well-written, and easy to understand. Narrative sections typically included de-
I
                  tails such as valve identification numbers, model numbers, operable redundant sys-
                  tems, dates of completion of repairs, etc. Root causes vere identified.
                  Many LER's presented information in an organized pattern with separate headings
                  and specific information that led to a clear understanding of the event. Previous
                  similar occurrences were properly referenced.
                  With so few LER's generated, a common casual link could not be established. These
                  LER's are indicative of performance problems identified in each of the functional
                  areas.
                  D.      Allegations                                                                                          i
                                                                                                                              t
                  During this period, two allegations received in previous SALP periods were resolved
                  by the NRC staff: (1) labor relations and technical concerns by a health physics                            1
                  technician (NRC Inspection Report No. 50-289/88-19); and, (2) concerns on health
                  physics technician qualification at TMI (NRC Inspection Report No. 50-289/87-24).                          {
                  A new allegation received during this period was from a private citizen on drug
                  abuse at TMI. The individual also implicated certain licensee employees to licen-
                  see representatives. The licensee completed their review of the matter with re-
                  sults not substantiating the allegation against the named individuals. However,
                  the licensee's review identified other personnel having drug test results with
                  indication of drug abuse. The licensee took disciplinary action.

                                                            Operating License No. DPR-50

                                                                  Response to SALP 87-99
                            On April 3, 1989, the NRC issued the Systematic Assessment of Licensee
                            Performance (SALP) Report for Three Mile Island Unit 1.                        A meeting to discuss
                            this report was held at the Three Mile Island Training Center on April 10,
                            1989.    Attachment I to this letter provides the GPUN written comments on the
                            SALP report.
                            We appreciate the opportunity to review with you the SALP Report and provide
                            our comments.      We continue to believe that this dialogue is the most meaningful
                            portion of the SALP process.                                                                                      !
                            It is our understanding that the NRC plans to conduct mid cycle SALP reviews to
                            assess progress and evaluate effects of licensee performance.                              We would
                            encourage this mid cycle review for TMI-l and are willing to participate.
                                                                                      Sincerely,

                                        RESPONSE TO SALP REPORT 87-99
              Overview
                                                                                                            1
                                                                                                            i
              Several sections of the SALP Report referred to issues on procedures. GPUN has                !
              established an Administrative Procedure Task Force which has corporate wide
              responsibility. This task force has developed a list of recommendations which              -j
              are currer.tly being implemented. The task force will continue to monitor the
              implementation of these recommendations.                                                    {
                                                                                                            ]
              On the Plant level, a new Procedure Specialist has been added to the staff to
              help improve the procedure preparation, change and review process. This                      ;
              individual also will assist in the training of the procedure preparers and
              reviewers. This effort has been largely associated with maintenance
              procedures.  In this area, we have increased monitoring of in field procedure
              compliance and quality by the QA Department, the Plant Nateriel Department and
              the management offshift tour program.    The final approval authority of plant
              prLeedures has been changed to the Department Heads in place of the O&M
              Director. We continue to believe the biennial review frequency is appropriate
              and that we have adequate resources to produce improvements on that schedule.
              Overall our emphasis on procedure Improvement is focused on technical,
              useability and human performance issues. This will strengthen the worker's
              ability to use the procedure on the job.
              Plant Coerations
              We are pleased the NRC acknowledged our improvement in this area. We believe
              the good, safe operation during this SALP period is indicative of our
              conservative approach to safe operations, operator professionalism and
              knowledgeable personnel. In addition, there is an active program in place to
              improve crew communications.
              Radiological Controls
              We ere in agreement with the analysis as presented. We have emphasized the                  ,
              importance of current surveys being posted. Also, significant scaffold
              erection in radiological areas is now an integral part of our outage planning
              and scheduling where appropriate.
              In addition to the reasons stated in the SALP Report which contributed to
              higher than estimated outage personnel dose, other factors included higher
              working area dose rates, implementation of a more rigorous program for discrete
              radioactive particle control and a greater percentage of respirator wcrk.                    ;

                      1.  HE E i*1 oroanisation
                          During.this SALP period the st&ffing of the Material Department was
                          comp 3eted.  In the planning and scheduling areas of this function we have
                          added additional planners, placed more emphasis on the planning process
                          and formed the outage'und non-outage scheduling groups. These steps,
                          along with the beplementation of the computerized GMS-2 work management
                          system cnd integrated scheduling will enable us to better plan, schedule,
                          and document maintenance work.
                    ,2.    Plant Materiel condition
                          As acknowledged in the SALP ' Report, the p' lant and its equipment are in
                          good materiel and operating condition. This contributed significantly to
                          the excellent operating record. Increased emphasis has been placed on the
                          identification and correction of minor materiel deficiencies.
                    3.    Water Chemistry Control Procram
                          GPUN has a strong water chemistry control program as discussed at the
                          April 28,~1989 meeting with the NRC. We do not believe the SALP Report
                          accurately characterizes this program and request that yoc re-review this
                          section of the SALP. We constantly strive for improvement and therefore
                          look forward to a clear assesscent with its associated basis from which we
                          can continue to progress.
                    Emercenev Preparedness and Security
                    We believe these are importent areas and will continue our emphasis and
                    management involvement.
                    Knoineerino/ Technical Sucoort
                    We are continuing our efforts to improve in this area. The recently completed
                    Technical Support self Assessment has provided and will continue to provide a
                    mechanism for improvements.
                    With regard to satisfying the ATWS rule requirements, we feel we are
                    essentially agreement in every area. The implementation schedule of 9R is
                    responsive and appropriate. This schedule has been extensively communicated to
                    and approved by the NRC.
                    Safety Assessment /Ouality Verification
                    In our safety review process all divisions are now following the corporate
                    procedure requirements. We believe the GPUN safety review process is a good,
                    sound program and will improve the quality of our safety reviews. We will

                  Subject: Systematic Assessment of Licensee Performance (SALP) Report No.
                                  50-289/87-99
                  On March 2, 1989, the NRC Region I SALP Board assessed the performance of Three
                  Mile Island Unit I for the 14 -month period from November 1,1987 to January 15,
                  1989. That assessment.is documented in the enclosed report. We have arranged to
                  meet with your staff onsite on April 10, 1989 to discuss the SALP.
                  At the meeting, please be prepared to discuss the assessment and any plans you have
                  to-improve performance. You may, of course, provide any comments you have regard-
                  ing the SALP at the meeting. Also, you may provide written comments within thirty'
                  days.after the meeting.

                  Thank you for your cooperation.
