integrated NRC. staff effort to collect available observations land data l on a periodic basis and to evaluate licensee performance on the~ basis- a;

!

of this-information. The program is supplemental, to normal regulatory j processes used to ensure compliance with NRC rufes and regulation SALP is intended to be sufficiently diagnostic to provide a rational basis for ' ,

allocating NRC resources and to provide meaningful feedback to the licensee's j management regarding the NRC's assessment of.their facility's-performan'ce q in each functional are An NRC SALP Board, composed 'of the staff members listed below, met on  ;

~ February 24, 1989, to review'the observations and data on performance, and !

to assess licensee performance in accordance with the guidance in NRC .. 1 Manual Chapter 0516, " Systematic Asser,sment of Licensee Performance." .The guidance an,d' evaluation criteria are summarized in Section III of this + 3 report.

II. SUMMARY OF RESULTS

,. Overview Management continued to demonstrate a high degree of personal

.,.

involvement in overall plant operation and quality programs; it has been aggressive and proactive in response to NRC safety concerns and in the support of quality improvement-initiatives. The effectiveness of improvement initiatives was demonstrated during the last half of the assessment period, especially in improved plant operations and 1 in a reduction of reportable events. However, the number-of reactor

.

'

trips attributed to equipment and personnel errors remained hig Management's continued support of an open communication environment )

and' staff training was eviden Staffing was viewed as.a utility strength; licensee personnel are responsible and forthright in identifying and resolving problems and display a positive safety attitude. Weaknesses were noted in the areas of maintenance, engineering / technical support and safety assessment / qualit verification. Maintenance related weakne'sses include the performance of the traveling maintenance crews, and the large number of equipment l failures causing forced outages. These. problems may be the result of plant aging and the lack of an aggressive prevention maintenance program. The engineering / technical support weakness is the lack' of ,

critical performance requirements in the original design basis j information particularly as this is needed in replacement of i outmoded parts. The safety assessment / quality verification I weaknesses are the timeliness'of completion of certain significan I technical issues, resource allocations, and some non-conservative decisions. The licensee performance was generally good and continued to show overall improvement, and was a good performe l As an example, emergency preparedness improved to a Category 1 as I a result of improved training, an independent audit program, and excellent interface with offsite emergency response officials, )

III. CRITERIA Licensee performance is assessed in selected functional areas. Functional areas normally represent areas significant to nuclear safety and the environment. Some functional areas may not be assessed because of little or no licensee activities or lack of meaningful observation Special areas may be addcd to highlight significant observation The following evaluation criteria were used to assess each functional area: Assurance of quality, including management involvement and control; Approach to the resolution of technical issues from a safety standpoint; Responsiveness to NRC initiatives; Enforcement history;

. Operational events (including response to, analyses of, reporting l

of, and corrective actions for); Staffing (including management); and Effectiveness of training and qualification progra However, the NRC is not limited to these criteria and others may have been used where appropriat On the basis of the NRC assessment, each functional area evaluated is rated according to three performance categories. The definitions of these performance categories are as follows:

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 appropriat Category 2: Licensee management attention to and involvement in the performance of nuclear safety or safeguards activities are good. The licensee has attained a level of performance above that needed to meet

,

regulatory requirements. Licensee resources are adequate and reasonably I

allocated so that good plant and personnel performance is being achieved. NRC attention may be maintained at normal level .

O

.

Category 3: Licensee management attention to and involvement in the performance of nuclear safety or safeguards activities are not sufficient. The licensee's performance does not significantly exceed that needed to meet minimal regulatory requirements. Licensee resources appear to be strained or not effectively use NRC attention should be increased above normal level The SALP report may include an appraisal of the performance trend in a functional area for use as a predictive indicator if near-term performance is of interes Licensee performance during the last quarter of the assessment period should be examined to determine whether a trend exist Normally, this performance trend should only be used if both a definite trend is discernable and continuation of the trend may result in a change in performance ratin The trend, if used, is defined as: l Improving: Licensee performance was determined to be improving near the close of the assessment perio Declining: Licensee performance was determined to be declining near the close of the assessment period, and the licensee had'not taken meaningful steps to address this pattern.

'I PERFORMANCE ANALYSIS ' Plant Operations- Analysis Evaluation of this functional. area was based on the results of ten. routine inspections by the resident inspector The enforcement history in this area identifie.1 no violation This was an improvement over. the previous assessment period 1 in which two Severity Level IV violations were identifie I i

Management invcivement in this area was excellent. The licensee j benefits from shift supervisors and line manag'ars who are knowledgeable in the history ;and operating c,heracteristics of j the facility. These managers.are generally involved in  !

both routine and off-normal operational activities. There was' ]

constant evidence of prior planning and assignment'of priorities, i Procedures for control of activities were well-stated, j controlled, and explici Senior sito management personnel wer q often present in the control room, communicated regularly with j the shift supervisor during 'all shif ts, ano toured the. plant on i a regular basis. Management's presence and involvement contributed to the generally high level of housekeeping ..

throughout the facilit Corporate n.anagement'has frequently j and effectively been involved in site activities and'has been onsite at least once a quarter. The safety review committees were adequately involved in reviewing and approving charges to operational procedures on a regular and emergency basis, q t

The licensee's response to the resolution of technical issues {

from a safety standpoint demonstrated a clear understanding 1 of the issues. Examples were the reducticn in power to fix the ]

unidentified leak rate before it reached Technical Spec,1fication (TS) limits and the installation of a ,iumper in the source range monitor to maintain a required interlock in the rod block system. Additionally, the licensee exhibited their conservative operating philosophy when the plant was placed in a safe condition after steam was detected in the steam tunnel, which turned out to I be a leak in the feed water heat exchange '

l l The licensee's responsivcnass to the resident inspectors initiatives and policies were timely and effective as demonstrated in the

'

.:

evaluation of using a control copy to repair a flange stea '

l leak, the placement of controlled procedures at applicable work stations in lieu of operators carrying procedures stamped working only copy, and evaluating potential generic concern identified at other sites. The licensee consistently met expectations with regard to schedule'and conten :

Operational events increased.during this assessment period over the previous period indicating a decline in~ performance. .There

.

were eight licensee event reports (t.ERs) issued that related to plant operations. Six automatic, reactor trips and one manual reactor- trip, resulting in two. engineered safety system .

j

,

actuations (diesel generator starts), occurred during this assessment period compared with three automatic trips with no . '!

engineered safety. system actuations in the previous assessment

'

period. Four of the automatic trips occurred early in the assessment" period with the reactor at 0% power. . One trip was with single rod motion during maintenance testing, and three resulted from spurious trips from the-26 year-old WRNM instrumentation system. Personnel error during switch down- ..

ranging was a contributing factor in one of the three WRNM; spurious trips. The WRNM system was replaced wit state-of-the-art equipment during the 1988 refueling outag The manual trip was caused by personnel error ~during grid synchronization. Two trips occurred. late in the assessment period'with the reactor at approximately 90% power. One wa caused by turbine equipment failure and the other by an offsite electrical line faul In response to the two trips, the licensed operators expeditiously took the correct emergency operating procedure (EOP) actions needed to maintain the plant in a safe condition. All events were promptly- and completely 4 reported. Operators routinely made use of procedures and drawings to conduct plant. operations and were familiar with TS and supporting administrative requirements associated with plant operations. Unit availability decreased during this assessment period to 75.5% from 79.7% during the previous assessment period. The decrease was not indicative of a proble Fire watch personnel carried out their assigned duties in a professional manne Staffing for the plant operations area continues to be excellent. A sufficient number of qualified licensed and non-licensed individuals were available to allow for routine shift coverage, training, and outage work without excessive use of overtime. Total overtime averaged 12% for all operations personnel during the assessment period. Positions were clearly identified and authorities and responsibilities were well-define .

During this assessment period, the licensee developed programs: 'l for task analysis of operators, operator goals toward continuing-professionalism, and'new E0P The fire protection. organization was adequately staffed with well qualified personnel. There is a full-time safety supervisor, who is a dagreed fire protection specialist and is the safety coordinator and. fire brigade-instructo I J

Training and qualification programs made a positive contribution to the understanding of work and adherence to procedures as indicsted by the' low number of personnel errors, lhe licensee'

adequately satisfied the requirement of training operators on a simulator by the use of another f acility's simulator. Three replacement exams were administered during the assessment period with a one passing. This was a decrease from the previous ..

period. Additional discussions are in:the- Engineering / Technical Support area of this report. Two training ~ positions were created and filled during the assessment period. One of the positions is filled by rotating shift supervisors through the position on an annual basis. The second position was created to assiht operations in the job task analysis program. The additional dedicated resources provided a means of feedback to the operator-licensing training program from experienced personnel. Two operations personnel with licenses were. attending college on a

Recommendations Non B. Radiological Controls Analysis Evaluation of this functional area was based on the results of four routine inspections by regional inspectors and ten inspections by resident inspector .

The enforcement history in this area during this period showed improvement with no violations when compared with one Severity Level IV violation in the previous perio Management involvement in ensuring quality was good and had improved since the previous assessment period. -The radiation work permit (RWP) and as low as reasonably achievable (ALARA)

programs were strengthened and included the' formation of an ALARA Committee. With NRC prompting, an extensive decontamination program was performed in the plant after. many cases of personnel contamination werc detected by the new whole body contamination monitors.

activities, installation of new whole body contamination monitors, and identified th'e lack of a formal hot. particle ]

program. .These efforts were necessary to improve contamination )

controls and radiation worker' practice Responsiveness to NRC. initiatives was generally good.with some .

exceptions. In response.to NRC.Information Notice 88-34,;the I licensee identified and corrected non-fuel special nuclear I material accountability proolems. Several-previously identified . j NRC concerns relating to whole body. contamination monitors,. 1 administrative controls'over high radiation area. keys, inservice l inspection (ISI) planningiand-coordination, skin dose calculation methodology, and gamma spectroscopy were adequately addressed during the_ assessment period. .However, followup evaluation of personal contamination event was relatively weak; the licensee was: slow to improve. control'of used protective clothing at-contamination boundaries; and the licensee was lax in l maintaining shoe covers and gloves at frisker station The licensee's approach to the. identification and resolution of radiological technical issues-was generally sound as exhibited by major revisions to the RWP system, continued improvements in personal dose tracking, good hot particle' skin dose assessments, and resolution of problems with vendor owned

, hipping casks. A weakness was identified concerning the- ,

determination of radiological protective measures based primarily on previous similar job The licensee continues.to perform'well in the radiological confirmatory measurements area with 56 agreements in 59 comparisons. Licensee performance of:the Radiological Environment Monitoring Program was satisfactory. The. total station dose (about 210 person-rem in 1987.and 160 person-rem in 1988) has

,. trended dcwnward over the last several assessment periods and l

reflects an improved ALARA performance. Due to an NRC initiative, the licensee sipped fuel and removed bad fuel. LThis resulted in radioactive gaseous effluent releases being' considerably reduced -

during the assessment period, reflecting the absence of.significant fuel cladding problems with the current fue The amount and l activity cf liquid radwaste releases remained at an acceptable i

level, Solid radwaste volumes-shipped to-licensed burial sites i

continue to decline as a result of implementing volume reduction technique The staffing levtis and qualifications of radiation protection personnel were generally adequate to implement the routine radiation protection and ALARA programs; experienced contract i

Evaluation of this functional area was based on the results'of i ten routine inspections performed by the. resident inspectors and I

six routine inspections by regional inspectors. Maintenance and surveillance were separate functional areas in the previous assessment period but have been combined as one functional area for this assessment period.

l The enforcement history in this area has declined from the i previous assessment period when there were no violations in either the maintenance or surveillance area.

tasks have been well planned and implemented, as have l continuing plant improvement programs. Three major tasks

completed during the 1988 refueling outage were the replacement /

diaphragm Problems were encountered in all three tasks that required additional management attention. The problems with the WRNM will be discussed in the Engineering / Technical Support section of this repor The problems with the RDS valves were identified during full stroke testing. After, substantial questioning by the NRC staff, the remaining valves were tested. Subsequently, all four valves were refurbished, modifications were initiated to improve the design, the valves were retested, and a TS amendment was initiated to full stroke test the valve every refueling outag The CRDS valve diaphragm problem was identified during post-maintenance testing and resulted in complete rework of the project. The field maintenance teams used mostly during outages did not perform maintenance up to the standards of the regular plant maintenance personnel. In the case of CRDS valve diaphragm, the initial work practices used were inadequate. Site quality control did not detect the errors during maintenance. Field maintenance team performance continues to be an area of concern to the NR Resolution of technical issu'es was viable, generally sound, and thorough during this assessment period. Occasionally, problems recur before they are effectively resolved, as demonstrated in the CRDS valve problems and neutron monitoring syste .

, i l The licensee was responsive to NRC concerns with the maintenance program and identified and corrected programmatic

'

and procedural deficiencies in the maintenance area. During this assessment period, the licensee made a management change l in the Engineering / Maintenance Department to create separate Engineering and Maintenance Departments. The change enabled the new superintendent of maintenance to devote his full time to maintenance activities. The licensee created a six-member team to write new procedures for maintenance personnel and to upgrade the format of existing procedures. Due to an NRC initiative, a root-cause analysis program was developed and is undergoing a trial implementation period before its final formatting and approval. These changes occurred late in the assessment period, making it difficult to assess the impact. A self-assessment in the maintenance area was performed during the assessment period. The licensee has committed its limited resources to resolving the issues of planning and scheduling, writing additional procedures, and improving maintenance tool and equipment control in an expeditious manne Maintenance and surveillance events accounted for three LERs during this assessment period. Maintenance and surveillance work on safety and safety-related systems and components were in most cases well planned and professionally performed with detailed instructions, drawings, and procedures being used at the job site. The work and post-maintenance testing performed

were well-documented.' 'Except for the CRDS diaphragm problem a small amount of rework was indicative of an effective maintenance program. Corrective action may not be effective in correcting g the root-cause of the problem as. indicated by: occasional j repetition of events, such as problems with the steam admission 4 valves and the source range neutron monito ~I

!

There has been a significant reduction in.the: plant equipment work request (WR) backlog. The WR backlog had-averaged approximately 180 items at the~ start of the assessment period l and had decreased to'approximately 90 at.the end of the assessment- )

period. A minimal number of preventive maintenance (PM). items- I'

required deferral during the assessment perio Improvements continue.in the PM program from.the: previous' assessment periods with the increased use of predictive analysis (using vibration and temperature monitoring)_on a variety of equipment. However,.

the large number of forced outages due to equipment failures may indicate that a more aggressive PM program is needed. Plant aging is an area of concern to the'NRC and may require more of the licensee's resources particularly as the' plant age The water chemistry appeared to be under good control as demonstrated by the licensee's trend charts of the various parameters. Although the laboratory had a technician performance testing program and used performance checks on the 4 analyses, the Quality Assurance / Quality Control (QA/QC) program for analytical measurements was weak. The-licensee's staff made only limited use of.QC charts and these were without t statistically-derived control parameters. The licensee is 1 correcting these weaknesses. The -laboratory facilities, including '

space and instrumentation, were adequate for monitoring the chemistry parameters. The results of the nor radiological confirmatory measurements program were goo The licensee had 11 of 13 initial comparisons in agreement (85%). The disagreements appeared to be due mainly to problems in reading a calibration curve accurately on a graph. The licensee is extensively

-

modifying the chemistry procedures to bring the water ~ chemistry program into conformance.with the Electric Power Research i Institute Boiling Water Reactor Owners Guidelines. Further, licensee representatives agreed to document-the variance between ,

their practices and these guidelines, j The licensee maintains a well-trained and qualified maintenance, surveillance, and chemistry staff. During outages,~ additional'

company maintenance crews are utilized to assist. plant personne The maintenance training program received accreditation by INPO in February 1988. To enhance the training' effort, the maintenance trainer position was changed.to report to'the Big Rock Point training supervisor rather than the Bay City supervinor. Increased attention to career. plans was implemented for all maintenance personnel, including repairme'n and technicians. Additional schools were provided to increase

D Emergency Preparedness j Analysis Evaluation of this functional area was based on the results of two routine inspections and one annual emergency preparedness (EP) exercis The enforcement history in this area did not identify any violations in either of the two routine inspection Two Severity Level IV violations in this area were identified during the previous assessment. No weaknesses were identified in the annual exercise. Although the Emergency Response Facility (ERF) appraisal was postponed because the control room design review had not been completed, the meteorology and dose l

assessment portions of the ERF appraisal were reviewed and reported as part of the exercise report. Both of these areas of the ERF appraisal were considered satisf actor Corporate and site management have been involved in site ]

activities in an effective manner. Independent audits of the

'

licensee's EP program were complete, timely, and thoroug A weakness identified in this area in the previous assessment period had been corrected. Manageme.nt attention to the EP program and cooperation with EP personnel has resulted in a better, more professional approach that includes surveillance and reviewing the interfaces between the licensee and state and local governments. A good working relationship is being maintained with Charlevoix County, Emmet County, and the Emergency Management Division of the State of Michigan, Management responsiveness to NRC initiatives has resulted in acceptable resolutions of concerns arising from the licensee's initial submissions. Through management and technical staff-cooperation, several Emergency Action Levels were revised according to NRC recommendations.

documented and maintained better, and record retrieval capability is good. Effective in January 1988, the EP training modules were reduced.by combining certain'ones which, in turn, reduced certain redundant emergency. response positions. As an example, a person training for a certain Technical Support. Center support position need not be completely retrained for a similar position in the Emergency Offsite Facility. Records indicate that 145 out of 156 people onsite are trained in emergency preparedness responsibility (93% coverage). Of these 145 persons, 65% have

participated in two or more drillsLin the past 2 years. .This clearly indicates the extensive scope of current emergency

The enforcement history represented a reduction in the i licensee's performance from the previous period. Two violations j were identified, one Severity Level III violation and one Severity Level IV violation. During the previous assessment period, no violations were issued. The Severity i Level III violation occurred at the beginning of the assessment 1 period, and a civil penalty was assessed. The vio'lation was for an inadequate vital area barrier that had existed since the plant was constructed, and because of the barrier's location, it was not identified previously by the licensee nor the NR The violations did not represent a significant program breakdown and neither of the violations resulted in direct safety problem Management involvement in assuring quality in this area was adequate. Management support for upgrading security equipment necessitated by aging equipment and NRC concerns was evident as demonstrated by the acquisition of new access control search equipment, completion of the closed circuit television upgrade project, and completion of the fence tightening and soil stabilization project Concerns identified in the previous assessment period were effectively addressed by the license The property protection supervisor (PPS) was very responsive to regional and resident inspector concerns. The PPS and his staff developed a program to analyze security data to determine program performance trends that have resulted in identifying l potential problems and have helped create a proactive security program. A higher level of security awareness among the general plant work force has reduced the high number of security violations caused by non-security personnel and has strengthened the security progra The licensee's responsiveness to NRC initiatives was adequate -

!

when violations and weaknesses were identified. Commitments i and requirements within the scope of the security plan were i generally met. When violations and weaknesses were identified, j the licensee took corrective action in a timely and effective manne Security events reported under 10 CFR 73.71 were properly id.'ntified, analyzed, and reported to the NRC as require There were three events reported during this assessment period, which wa= the same number as that reported during the previous assessment period. This low number of events over the two assessment periods was considered excellent.

The licensee submitted information to demonstrate a more conservative approach for protecting against fire-induced I spurious operations of high/ low pressure interfaces than was required by the NRC. Modification packages showed strength in the area of documentation and general technica1' adequacy.

Responsiveness to NRC initiatives was generally timely an viable except for the operator licensing examination conducted _

in 1988. The exam had to be cancelled after the examiners arrived at the site, due to the failure of the licensee to provide up to date, accurate reference material.

operational analyses. The Board was also effective in reviewing

'LERs for completeness and determining areas that required additional investigation. The Plant Review Committee (PRC) had performed adequately in initiating investigations and ensuring followup of corrective actions for previously. identified violations, reportable events, and areas of weakness. The NRC was concerned with the PRC's non-conservative decision to continue up in power following the' discrepancy in WRNM indications and heat balance calculations during initial testing of the WRNMs. Also o concern was the licensee's inquiry for a possible TS change to pull rods to go critical without proper source range indicatio The open items for both the PRC and Nuclear Safety Board were tracked on the licensee's tracking system, and the licensee was active in ensuring that scheduled dates for closures were me The licensee maintained an open environment for the discussion l of problems and improvement opportunities. Also, at the urging of the NRC, a trial root-cause analysis program was implemente J at the end of the assessment perio A number of technical issues, some of thera unique to the Big l Rock Point plant design, were resolved, including a major  ;

effort on RDS valve testing requirements. 0ther issues remain I open, including the validation and verification (V&V) of software for the new power range monitoring instrumentation, an exemption i from fire protection requirements relating to the screenhouse, ,

revision of the Offsite Dose Calculation Manual (00CM), E0Ps, I plans for cont-ol room ~ simulation, and station battery service test requirements. The licensee displayed a good understanding l of the safety issues and was generally responsive to the staff, i l

The licensee's Integrated Living Schedule (ILS) was used to provide visibility to and status of NRC-and licensee-initiated safety. issues and to prioritize the application of resources to resolve the issues. ILS updates were the subject of two licensee-requested semiannus.1 meetings among corporate, plant, and NRC managemen The ILS clearly provides a mechanism to justify focusing limited resources on a few high priority issues. However, the RDS and turbine load rejection problems-have for years been both high priority and unresolved issue ~

.Further examples of repeated schedule extensions were for-the sof tware V&V, ODCM revisions, and Final Hazards Safety Report updates. These frequent extensions raise questions about adequacy of resources being allocated to ILS items. Shile it is acknowledged that improvements in resource commitments have been made, additional emphasis is neede Licensee responsiveness to generic communications were timely and thorough, as evidenced by-their acceptable responses to NRC bulletins on fastener testing (Bulletin 87-02) and

non-conforming materials (Bulletin 88-05). The licensee was very responsive in taking actions to resolve allegations that were turned over by the NRC to the licensee for corrective action The onsite QA group placed emphasis for its surveillance inspections on those systems with the highest safety significance, such as the reactor protection system, post accident system, RDS, and core spray system. The licensee l introduced the probabilistic risk concept in the surveillance  ;

and inspection program during this assessment period. The concept is based on core damage / release of fission product l Two surveillance performed using this concept were the ISI and l RDS valve testing. The enhanced performance incentive program I was a positive licensee initiative to control the use of QA l resources for work involving in-line reviews of procedures '

and maintenance orders. The first plant group selected for the program was the instrument and control department, because l of past outstanding performance. The program has the approval of NRC regional staff. Safety review committees and feedback from QA/QC activities were used to provide critical I self-assessments to the corporate management and to improve work activities associated with plant operations. The NRC has concerns that the quality assurance surveillance and audits are not performance based inspections and may have an inadequate number of hours budgeted to do observations of actual work in progress.

l i Staffing of the licensee's onsite QA/QC department remained

generally stable over the assessment period. The staff is composed of technically oriented individuals with extensive plant experience who exhibit a good understanding of programmatic requirements and exhibited a high degree of professionalism.
