9 , INTRODUCTION The Systematic Assessment of Licensee Performance (SALP) program is an integrated NRC staff effort to collect available observations and data on a periodic basis and to evaluate licensee performance based upon this information. SALP is supplemental to normal regulatory processes used to ensure compliance with NRC rules and regulations. SALP is intended to be sufficiently diagnostic to provide a rational basis for allocating NRC resources and to provide meaningful guidance to the licensee's management to promote quality and safety of plant operatio An NRC SALP Board, composed of the staff members listed below, met on May 17, 1988, to review the collection of performance observations and data, and to assess licensee performance in accordance with the guidance in NRC Manual Chapter 0516, "Systematic Assessment of Licensee Performance." A summary of the guidance and evaluation criteria is provided in Section II of this repor This report is the SALP Board's assessment of the licensee's safety performance at Wolf Creek Generating Station for the period March 1, 1987, through March 31, 198 SALP Board for Wolf Creek Generating Station: | |||

___ _____-_ _.-__ _ | |||
, , | |||
, | |||
little or no licensee activities or lack of meaningful observation Special areas may be added to highlight significant observation One or more of the following evaluation criteria were used to assess each functional area: Management involvement and control in assuring qualit . Approach to the resolution of technical issues from a safety standpoin . Responsiveness to NRC initiative . Enforcement histor . Operational events (including response to, analysis of, and corrective actions for). Staffing (including management). | |||
However, the SALP Board is not limited to these criteria and others may have been used where appropriat Based upon the SALP Board assessment, each functional area evaluated is classified into one of three performance categorie The definitions of these performance categories are: | |||
Category 1. Reduced NRC attention may be appropriate. Licensee management attention and involvement are aggressive and oriented toward nuclear safety; licensee resources are ample and effectively used so that a high level of performance with respect to operational safety and construction quality is being achieve Category 2. NRC attention should be maintained at normal level Licensee management attention and involvement are evident and are concerned with nuclear safety; licensee resources are adequate and are reasonably effective so that satisfactory performance with respect to operational safety and construction quality is being achieve Category 3. Both NRC and licensee attention should be increase Licensee management attention or involvement is acceptable and considers nuclear safety, but weaknesses are evident; licensee resources appear to be strained or not effectively used so that minimally satisfactory performance with respect to operational safety and construction quality is being achieve ; | |||

III. SUMMARY OF RESULTS The SALP Board review revealed areas of strength in fire protection and security with an increase in performance from the previous SALP perio Performance in the areas of emergency preparedness and surveillance remained consistent with the previous SALP period. All other areas revecled a decline in performance or a declining trend from the previous SALP period. The overall decrease in performance is due, in part, to the failure of licensee management to maintain effective control of major outage The licensee's performance is summarized in the table below, along with the performance categories from the previous SALP evaluation perio Previous Present Performance Category Performance Category Functional (02/1/86 to 02/28/87) (03/1/87 to 03/31/88) Plant Operations 2 2 Radiological Control 2 2 Maintenance 1 2 Surveillance 2 2 Fire Protection 2 1 Emergency Preparedness 2 2 Security 2 1 Outages 2 3 Quality Programs and 2 3 Administrative Controls Affecting Quality Licensing Activities 1 2 Training and Qualification 1 2 Effectiveness I PERFORMANCE ANALYSIS Plant Operations Analysis The assessment of this area consists chiefly of the activities of the licensee's operational staff (e.g., licensed operators and nuclear station operators). It is intended to be limited to | |||

., , | |||
operating activities such as: plant startup, power operation, plant shutdown, and system lineup Thus, it includes activities such as reading and logging plant conditions, responding to off-normal conditions, manipulating the reactor and auxiliary controls, plant-wide housekeeping, and control room professionalis This area has been inspected on a continuing basis by the NRC resideist inspectors and on several occasions by NRC regional inspectors. Specific areas inspected included operational safety verifications, safety system walkdowns, follow up on significant events / problems, and review of licensee event reports (LERs). | |||
One violation was identified in this functional area and, while it indicated additional management controls were needed, corrective action was promptly initiated by the licensee. Also, one of the escalated enforcement violations listed in the outage functional area included three examples of problems relating to the operations functional area. Four LERs were issued by the licensee in this functional area. These four LERs had no major effect on plant safety. One of the LERs concerned the one violation that was identified in this are The remaining three LERs were ali personnel errors and were indicative of a failure | |||
, | |||
to pay attention to detai Corrective actions initiated by licensee management included requiring the use of procedures in additional areas in operations. At the end of the SALP period the use of procedures in operations was much improve Operational events and NRC observations showed that operations interface with other departments is lacking. There has been an apparent failure of operations to make effective use of technical support groups. In some cases even when technical support groups became aware of problems and provided input to operations, the input was ignored or was lost. There are two examples. The first was when operations was not responsive to Nuclear Safety Engineering's information and advice concerning the essential service water (ESW) pipe-wall thinning issue. As a result, timely corrective action was needlessly delayed. The second was when engineering provided disposition to repair a section of thinwall safety related pipe and the disposition was misplaced for approximately 3 month In general, operator performance, as observed by the NRC | |||
, | |||
inspectors, has been good. Control room professionalism has l | |||
' | |||
been maintained and good operator morale exhibited. At times, however, the operators failed to pay attention to detai Two | |||
; examples of this are given below: | |||
; | |||

. . | |||
The first example occurred when vital batteries were allowed to be depleted over a 30-hour time span without a procedure being available to provide alternate AC power to the battery chargers, and without bus voltage being observed carefully or without periodically observing current readings and comparing them to expected value The second example was the uncontrolled use of operator aids. When ESF actuations occurred as a result of the degraded batteries, the operators relied on the uncontrolled aids in determining that certain manual isolation valves were shut. The valves were, in fact, cpe When the valves had been opened, the uncontrolled aid had been forgotten. This resulted in the undesirable placing of lake water in each of the steam generator The licensee continues to give strong management support to the college degree program for operations personnel. The number of operators with engineering degrees or working toward degrees is considered to be a plu The number of operators with senior reactor operator licenses exceed the number of operators with reactor operator licenses by more than 2 to 1. This allows the licensee more versatility in the use of the operators, while at the same time giving operators additional training and mobilit In general, the licensee maintains a 6-shift rotation of their operating crew This allows for a better utilization of the crews, less overtime, and increased trainin . Conclusions The overall assessment of this area indicates that improvements need to be made. As stated in the previous SALP report, licensee attention to detail in this area can be improve The use of procedures in operations was noted to improve; however, this occurred only after the situation had been allowed to deteriorate to an unacceptable leve The examples of inattention to detail and the lack of effective operations interface with other departments reflects an ineffective management oversight in this functional are Staffing in this area is considered a strength, along with good control room professionalism during power operation The licensee is considered to be in Performance Category 2 in this area, with a declining tren _ _ _ _ _ _ _ - _ | |||

Radiological Controls Analysis The assessment of this functional area includes the following areas of activity which are evaluated as separate subareas to arrive at a consensus rating for this functional area: | |||
(a) occupational radiation safety, which includes controls by licensees and contractors for occupational radiation protection, radioactive materials and contamination controls, radiological surveys and monitoring, and ALARA programs; (b) radioactive waste management, which includes processing and onsite storage of gaseous, liquid, and solid waste; (c) radiological effluent controls, which includes gaseous and liquid effluent controls and monitoring, offsite dose calculations and dose limits, radiological environmental monitoring, and the results of the NRC's confirmatory measurements program; (d) transportation of radioactive materials, which includes procurement and selection of packages, preparation for shipment, selection and control of shippers, delivery to carriers, receipt / acceptance of shipments by receiving facility, periodic maintenance of packagings and, for shipment of spent fuel, point of origin of safeguards activities; and (e) water chemistry controls, which includes primary and secondary systems affecting plant water chemistry, water chemistry control program and program implementation, chemistry facilities, equipment and procedures, and chemical analysis quality assuranc Nine inspections were performed in the area of radiological controls during the assessment period by Region-based radiation specialist inspector There were five violations and one deviation identified in this functional are _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ - _ _ _ | |||

a. Occupational Radiation Safety The licensee's programs for occupational radiation protection, radioactive material and contamination controls, radiological surveys and monitoring, and ALARA programs were inspected four times during the assessment period. Two inspections were conducted during normal plant operations, one inspection during a scheduled refueling outage, and one special inspection after the release of radioactive material to the local county landfil The licensee's exposure for 1986 was 142 person-rem compared to the national PWR average of 392 person-re During 1987, the licensee's person rem exposure was 124 compared to a national PWR of 376 person-re The size of the radiation protection staff was adequate to support plant operations. A low personnel turnover rate within the radiation protection group was experienced during the assessment perio The licensee's approach concerning the resolution of technical issues indicated their understanding of issues was generally apparen Acceptable resolutions were generally proposed in response to NRC initiative Those violations identified in the radiation protection program were an indication of a lack of management involvement in assuring quality and worker trainin The two concerns noted during the previous assessment period which included: (1) lack of steam generator mockup training and (2) lack of health physics supervisory personnel presence in the plant to oversee and evaluate ongoing radiation protection activities, had not been fully resolve The licensee had made changes in the position of radiation protection manager, an individual with limited experience and not qualified in accordance with Regulatory Guide was aupointed to the position. The licensee recently | |||

A review of gaseous and liquid releases indicates that offsite doses were well below Te:hnical Specification limits. Three concerns were identified relating to: (1) liquid effluent monitor setpoints, (2) condensate stora4e tank analyses, and (3) radiation monitor calibration' dat \ , | |||
The offsite radiological environmental ronitoring program was inspected once during the ac40sment period. No violations were identified.

Maintenance Analysis TheassessmentofthisareaiM1udesalllicenseeandcontractor activitics associated with preventive or corrective maintenance of instrumentation and control equipment'and mechanical and electrical system This area was inspected on a continuing basis by the NRC resident inspectors and periodically by NRC regional inspector There were two violations identified in this area. These | |||
' | |||
violations involved the failure of the licensee to request a code ex.emption when required and three examples of a failure to ( | |||
follow precedures. There were 11 LERs issued by the licensee in this functional are One LER was due to inadequate pct-maintenance / testing or, a containment isolation valve, another LER was due to an accidental mispositioning of a breaker switch. | |||
l l The escalated enforcement action that was taken due to the problems which occurred during the fall refueling outage revealed significant problems within the mainterance organization. These problems consisted of workers failing to follow procedures, inadequate proceduras, inadequate control over special processes, and an overs ' 5reakdown of management oversite of maintenance activities dunng the eefueling outage. | |||

~/ During the last quarter of the SALP period, the maintenance management organization underwent significant changes Maintenance was combined with facilities and modificat. ions to form maintenance and modifications. This change combines all maintenance activities under a single manager. The superintendent of maintenance transferred to the outage plannin0 group and the manager of facilities modifications became the manager of maintenance and modifications. In addition, some lower level h.anagers were transferred and some positions were eliminated. These changes appear to have significantly strengthened the maintenance are . Conclusions The NRC found evidence of upper management support for a strong maintenance progra However, the implementation of this program was not adequately carried out. Management oversight of the day-to-day activities in the area of maintenance declined | |||

The enforcement history in this functional area identified two violations during this assessment period. Also, several LERs were issued by the licensee during this assessment perio Personnel errors and inadequate procedures were the predominant causes of the violations and reportable events during this assessment period. This resulted in examples of missed surveillances, late performance of surveillances, inadequate post-test review, and undesirable engineered safety feature actuations which are similiar to problems which occurred during the previous SALP perio During the previous SALP period, the licensee was rated a SALP Category 2 in this functional area with a decreasing tren Although the enforcement and reporting history indicate improvement, as noted above, similar procedural and personnel errors are being repeated during this SALP perio . Conclusions The overall assessment for this functional area indicates a program for scheduling and tracking of surveillance activiG es that appears adequat Procedures in some cases did not address all Technical Specification surveillance requirements adequately. The repeat procedural and personnel errors indicate that additional management involvement is needei The licensee is considered to be in Performance Category 2 in this functional are __ - _ _ | |||

13 Board Recommendations Recommended NRC Actions The level of NRC inspection in this functional area should be consistent with the basic inspection program, Recommended Licensee Actions The licensee is encouraged to perform an indepth review of the Technical Specification surveillance requirements and ensure that the surveillance procedures address these requirements. Also, additional management involvement with surveillance activities is encourage E. Fire Protection Analysis The assessment of this area includes routine housekeeping (combustibles, etc.) and fire protection / prevention program activities. Thus, it includes the storage of combustible material; fire brigade staffing and training; fire suppression system maintenance and operation; and those fire protection features provided for structures, systems, and components important to safe shutdow This area was inspected by a Region-based inspector and on a continuing basis by the NRC resident inspectors. During this assessment period the fire protection group went through some organizational changes. One change was the transfer of the fire protection training duties from the supervision of the fire protection engineer to the trainir.g department. The other change was the transfer of the fire protection group from the plant support organization to the operations organizatio The following observations were made: | |||
. The licensee has made significant improvement in the area of administrative controls for fire barrier penetrations and opening Especially significant has been the reduction of missed fire watch patrol . Control of transient combustibles has been effectiv However, housekeeping could be improved in the area where trash is being deposited in other than approved containers (example: openings in tube steel). | |||
. Fire brigade / watch training continued to be outstandin The transfer of the fire training group to the training department has shown no adverse effect . . | |||
The licensee instituted a program to identify all fire barrier penetration seals that were either never sealed or removed and not resealed. This was an extensive program which the licensee aggressively pursued and complete . Conclusions The licensee has shown significant improvement in their fire protection / prevention progra Management involvement, both in the program as well as training, was evident. The major reason for the improvement in this area has been the continuing dedication and hard work of the well qualified fire protection engineer and training instructo The licensee is considered to be in Performance Category 1 in this are . Board Recommendations Recommended NRC Actions The level of NRC inspection in this functional area should be consistent with the minimum inspection program, Recommended Licensee Actions The licensee should assure that the recent organizational changes that have the fire protection engineer reporting to a different group and at a lower management level does not result in a reduction of management suppor F. Emergency Preparedness Analysis The assessment of this area inciudes the licensee's preparation for radiological emergencies and response to simulated emergencies (exercises). Thus, it includes emergency plan and implementing procedures; emergency facilities, equipment, instrumentation, and supplies; organization and management control; training; independent reviews / audits; and the licensee's ability to implement the emergency pla During the assessment period, four emergency preparedness inspections were conducted by Region-based and NRC contractor inspectors. One of these inspections was the observation and evaluation of an annual emergency response exercise by a team of | |||
, | |||
NRC and contracter inspectort. During the exercise, four l deficiencies from a previous exercise were closed and one new | |||
! | |||
deficiency was identified. The deficiency identified during the exercise involved incorrect classification of the emergency as l | |||
l l | |||
. . | |||
an unusual event rather than an aler The licensee's overall performance during the exercise was evaluated as good. The NRC staff concluded that licensee emergency response personnel demonstrated their ability to protect the health and safety of the publi Three routine inspections resulted in identification of three violations. One violation involved failure to document required communication tests of the emergency response facilities. The other two violations, one of which was a repeat violation, involved tailure to determine availability of required emergency preparedness personnel in the event of an accident. Training was identified during the previous SALP period report as an area needing management attention. The licensee has developed lesson plans, revised training requirements, and implemented a more efficient record management syste The 1987 SALP report stated, "However, several changes were made to the onsite emergency planning administrator (EPA) position, and the replacement EPAs have had little previous experience in this area." Due to attrition, new inexperienced personnel have been assigned the onsite emergency planning and preparedness responsibilities. Discussions held with onsite management revealed a difference of opinion as to what the functions of the onsite emergency preparedness coordinator were and would be in the future. The offsite emergency preparedness administrator is located in Wichita, Kansas. The licensee ha; recently added another level of supervision above the EPA, removing the EPA further away from plant management. (This reorganization presently is awaiting NRR approval.) The emergency preparedness program appears to be in a trantition phase with the shift in lead responsibility for emergencf program to the corporate offic . Conclusions The violations issued in shift staffing and augmentation indicate that the personnel notification method and procedure requires additional improvement. Hansgement attention should be devoted tu meeting regulatory requirements and licensee commitment Licensee management attention and involvement are evident; licensee resources are adequate and reasonably effective so that | |||

The inspection findings for this evaluation period indicate, overall, that the licensee's emergency preparedness program is adequate to protect the health and safety of the publi The licensee is considered to be in Performance Category 2 in this are . Board Recommendations Recommended NRC Actions NRC attention should be maintained at normal level Attention should be directed to licensee action taken toward correcting the call-out drill response and shift augmentation response time Recommended Licensee Actions The level of management attention to the implementation of the emergency preparedness program should be increased to ensure proper response to NRC identified concerns relating to call-out drill response and shift augmentation response times. The licensee should expedite correction of the call-out drill response and shift augmentation concer Management should review the distribution of onsite and offsite emergency program areas of a thority and responsibilitie G. Security Analysis The category of security relates to all activities whose purpose it is to ensure the protection of the plant. Specifically, it covers all aspects of the security program including ancillary efforts such as fitness for duty and access authorintion program Examples are: the licensee's overall management involvement ir, e-tablishing protective policies; designing physical security systems; submitting the security plan and implementing associated procedures; selecting, training, equipping, and supervising personnel; maintaining the hardware ' | |||
that suppcrts the program; and auditing and measuring the performance of the security progra This area was inspected on a continuing basis by the NRC resident inspectors and on a periodic basis by the NRC Region-based inspectors.

There was evidence of prior planning and assignment of priorities. _ Policies and procedures are well stated, appropriately disseminated, and understandable. Decisionmaking was usually at a level that ensured adequate management revie The.new corporate structure, which includes a repositioning of the Quality Assurance Department, is committed to continuing an independent and effective oversight of security-related matter Management reviews of identified security ratters were timely, thorough, and technically sound. The init.a1 review of security incidents has improved and further examination for generic significance has been enhance Records were generally completo, well maintained, and available. Rarely were procedures and policies violated. However, ;ome cases of personnel failure have occurred and these appear to be associated with temporary employee hiring practices. Corrective action on licensee identified violations was generally effectiv A clear understanding of security issues was demonstrated and subsequent decisions reflected reasonable and prudent judgement on the part of management. These kinds of judgements were also demonstrated in the Training and Human Relations Departments where security's ancillary efforts, such as fitness for duty, continual observation of employee's behavior, and the access authorization programs were manage There has been a major organizational restructuring of the Quality Assurance (QA) Departmen The chanaes have been too recent to evaluate their impact on the herett fore strong security oversight effort. There is some concern that these changes will not provide the level of audit expertise previously provide A review of these changes and the quality of the audits performed will be necessary in the futur The licensee has been usually responsive to NRC initiatives, but there continues to be two long standing regulatory issues attributable to the licensee. These are control room access and alarm assessment capabilit Technically sound and acceptable resolutions were proposed initially in most cases, but timeliness of resolution for these outstanding issues is slo After considerable discussion, the licensee agreed that their CCTV system had degraded and proposed proper corrective action One major violation concerning security personnel attentiveness was directly attributable to a member of the security | |||
, organization. It was promptly and effectively correcte A few l | |||
minor procedural mistakes by security personnel have occurred, | |||
' | |||
but were not repetitive. These mistakes appear to be indicative | |||
; | |||
of a need to enhance the selection process for temporary l | |||
security personnel and to be persistent in programmatic | |||
' | |||
training. | |||
l t | |||
_ _ _ _ _ | |||
+ . | |||
Occasional computer outage related events, construction / outage worker misunderstandings of security requirements, and maintenance related activities were attributable causes to violations. These events were identified and reported in a timely manne Security organization positions were clearly identifie Authority and responsibility was clearly defined. This included the relationship with the rest of the corporate organization.- A new squad manning structure has allowed for training and practice in squad response tactics. Temporary contract personnel, while not meeting anticipated standards, have been utilized to staff appropriate watchperson billet However, the employment practices used for these temporary watchpersons, combined with their lower experience levels and abbreviated training, appear to have had some adverse impact on the security operation. It did accomplish the overall goal of providing relief for the more experienced offi ers and to make them available for more critical task . Conclusions The licensee appears to have an ample number of supervisors, fully qualified security officers, and support personnel assigned to the security department to comply with the several security plans. With the exception of a few minor procedural errors, the security force had operated at a high level of performanc The 'icensee management's attention and involvement with nuclear security is evident. Licensee resources were appropriate and effective so that there was very good performance with respect to site physical and personnel securit The licensee is considered to be -:, Performance Category 1 in this are . Board Recommendations Recommended NRC Actions The NRC inspection level of the security program should be consistent with the minimum inspection program, with some exceptions. Exceptions where a more expanded inspection effort is recommended include: licensee measures to enhance and maintain physical security systems; methods for selecting, training, equipping, posting and supervising security personnel; and changes to the QA function where audits are performed to measure the performance of the security program and its ancillary efforts. | |||

19 Recommended Licensee Actions The licensee should continue to probe the causative factors of security events for broader implications and adjust programs, training, disciplinary actions, maintenance, and engineering responses appropriately. The organizational adjustments made in the QA area should be closely monitored to ensure that the high quality of the security oversight program continue H. Outage Analysis The assessment of this area includes all licensee and contractor activitiesassociatedwithmajoroutages. It includes refueling, outage management, major plant modifications, repairs or restoration to major components and all post-outage startJp testing of systems prior to return to servic This area was inspected on a continuing basis by the NRC resident insp:ctors, and periodically by NRC regional inspectors. In addition, an inspection was performed by a safety system outage modification inspection (SCOMI) team. The inspections included refueling activities, outo s management, planningandscheduling, staffing,majorcomp.mnts/ systems repairs and modification, and startup testin The licensee had two major outages during this SALP perio There was a refueling outage which lasted approximately 101 days and an outage to replace leaking reactor vessel 0-rings which lasted approximately 16 days. Refueling outage activities included replacement of Raychem splices, replacement of eroded essential service water pipe, annual inspection of the diesel generators, removai of heaters from Limitorque valve operators, replacement of reactor coolant pump "B" number one seal, replacement of the trip mechanism shafts on the reactor trip breakers, replacement of the tube bundle in the jacket water heat exchanger for diesel generator "A", rework of Valcor valve operators, cleaning of condenser tubes and inspections for thin wall pipes. There were numerous significant operational events which were attributable to causes under the licensee's control in this functional are There were four violations identified in this functional are Two of the violations involv.d escalated enforcement action and a proposed imposition of Civil Penalty. There were two LERs issued by the licensee in this functional area. The two LERs were on events that resulted in violations being issued. | |||

. . | |||
The two violations that resulted in escalated enforcement involved examples of procedural control weaknesses that the NRC considered significant. These weaknesses indicate management failed to provide an appropriate level of management oversight of safety-related activities. This is evidenced by the examples sited below as well as other areas in this repor Management oversight of outage activities was less than adequate as pointed out by the six examples of failure to follow procedures and four examples of inadequate procedures listed in the escalated enforcement packag The NRC staff was concerned with the licensee's lack of indepth analysis of these events. The licensee's ability to perform root cause analysis and implement timely and appropriate corrective actions was a noted weaknes During repair efforts on thin wall pipe due to erosion / corrosion the licensee experienced some difficulty. The licensee had on site a contractor workforce knowledgeable and experienced in the forming, fitting, rigging, and aligning of heavy pipe. The licensee decided to repair the thin wall pipe with their permanent maintenance workforc The maintenance workforce was not as experienced in this area as the contractor workforc This resulted in significant problems due to failure to follow procedures, failu.*e to follow work instructions, and failure to accomplish work activities by appropriately qualified personne Maintenance management failed to realize the scope of work was beyond their expertis The licensee was generally responsive to NRC concerns, however, there was a lack of aggressive response to identified problems prior to NRC involvement. The licensee's investigation of outage related events indicated a less than aggressive approach to the resolution of technical issues. The 0-ring outage, which was the second najor outage of the year, indicated that the licensee failed to control the 0-ring cleanli ess. The licensee decided to restart the plant after the first outage with known inner 0-ring leakag . Conclusions The licensee's ability to plan, manage, and maintain control over complex outage evolutions was inadequate and resulted in escalated enforcement action. The licensee apparently failed to beli 2 in and enforce strict procedural compliance. Aggressive management involvement to address problems that occurred during the outage was lackin The licensee is considered to be in Performance Category 3 in this are _j | |||

21 Board Recommendations Recommended NRC Actions | |||
_ | _ | ||
. Supplemental NRC inspections should be performed prior to and during the next major outag Recommended Licensee Actions The licensee should ensure that lessons learned from the previous outages are identified and reviewed for program improvements. The results of this review should be incorporated into outage planning and contro I. Quality Programs and Administrative Controls Affecting Quality Analysis The assessment of this area includes all management control, verification and oversight activities which affect or assure the quality of plant activities, structures, systems, and component This area may be viewed as a comprehensive management system for controlling the quality of verification activities that confirm that the work was performed correctl The evaluation of the effectiveness of the quality assurance system is based on the results of management actions to ensure that necessary people, procedures, facilities, and materials are provided and used during the operation of the nuclear power plant. Principal emphasis is given to evaluation of the | |||
, effectiveness and involvement of management in establishing and assuring the effective implementation of the quality assurance prograa along with evaluation of the history of licensee performance in the key areas of: committee activities, design and procurement control, control of design change processes, inspections, audits, corrective action systems, and record In order to more clearly define the specific strengths and weaknesses noted in this functional area, the analysis is divided into three areas, as discussed below: | |||
f Engineering l | |||
, | |||
! This area has been inspected on a routine basis by the NRC l resident inspectors and by a SSOMI team inspection during ( the assessment period. | |||
I The staffing in the engineering area is generally adequate in terms of numbers, but it is weak in experience and training. Further, the weaknesses identified by the 550MI inspection are indications that the communications between the plant operating staff and the engineering organizations l | |||
. . | |||
were poo In one case, engineering made a change to the cooling system for an electrical equipment room,.which required manual adjustment of a flow control valve to adjust the temperature. Since the temperature in this room was required to be maintained within a relatively narrow range, a surveillance program to ve-ify the temperature should have been instituted but was not. As a consequence, the qualified life or performance of the equipment may have been affecte In another instance, it appeared that the operating staff failed to ask for engineering guidance when performing a maintenance activity that resulted in a deep discharge of the safety-related station batteries and disablement of the vital AC buses at the same time. This in turn led to the introduction of lake water into the secondary side of the steam generator The S50MI report includes a concern that appears to be largely attributable to engineering since it involved a failure to properly evaluate the effect of a temporary modification. The modification involved application of a clamp to keep a safety-related damper in the control room emergency ventilation system open. Had actuation of the damper been required, an operator would have had to remove the clamp. The application of the clamp in such a manner violated the intent of the Technical Specification for system operabilit There were also three LERs that were at least in part attributable to engineering activitie In each case, the LERs became necessary because there were errors in design documents such as drawings, specifications, and instrument set point dat b. Quality Assurance This area has been inspected by both the NRC resident inspectors and regional inspectors. In addition, the SSOMI team inspected the areas of procurement, material storage, and audit activitie There were two violations in the areas of procurement and of material receipt. Additionally, some of the problems in the management of the outage were related to Q The licensee had received, accepted, and installed a noncode part which formed a portion of the reactor coolant system boundar An audit after the plant restarted disclosed this, and subsequent waiver to the code was granted. | |||

, | |||
The reactor vessel head 0-rin'g seals were not correctly inspected prior to installation. Although this was not the major contributor to the 0 ring leak, it showed a tendency for quality performance to be at pro forma leve During the outage, there were problems with the weld repairs to the essential service water systems. The'e problems included the issue of inappropriate welding materials and welders making welds for which they were not qualified. These problems were uncovered by quality checks, but the investigation revealed that QA had missed several opportunities to identify the problems earlie The licensee's vendor audit program did identify a problem with the certification of fuses purchased from a supplie lhe licensee reported the facts to the NRC. Follow up action by the NRC resulted in the issue of an Information Notic The licensee had not conducted training in root cause determination. Corrective actions tended to be focused on specific events and did not often probe for the underlying cause For example, when a four-way valve on the MSIV actuator failed, the original root cause deter.nination was not correct. The redesigned valve subsequently faile When incorrect fasteners were found in the charging pump check valve, they were replaced. No determination was made as to whether the problem was the fault of the fastener or the valve manufacture c. Management and Administrative Controls This area has been inspected on a routine basis by NRC resident inspectors and regional inspector During this SALP period, the licensee realized the existence of problems with safety-related pipe wall thinning. NRC had two basic concerns with this issue. The first concern was that the short term operability determination of the thin wall pipe was not technically sound in that it was made by plant management without input from engineerin Management did not reassess system operability even after engineering made the determination that the pipe did not meet code requirements. Plant management communications with engineering was not adequate. The second concern was with long term corrective actions. Plant management's narrow focus on the issue of short-term operability showed that their understanding of the issue was lacking. The question of generic application of one thin wall pipe to other areas in the plant was not addressed in a timely manner. It was not until these i | |||
m _ | |||
. -_ ____ _- _. | |||
.- .- | |||
issues were raised by Nuclear Safety Engineering and the Nuclear Safety Review Committee that appropriate corrective actions were begun. The operational response to this problem was not timely and lacked thoroughness. The above is one example of a lack of management involvement in assuring quality. Other examples have been cited in other SALP area The enforcement history in the area includes seven violations and no deviations. Four violations were related to the environmental qualification of equipment. Ten LERs were issued by the licensee in this area. Eight of these LERs were related to control room ventilation isolation system (CRVIS) actuations. Six of these were due to problems with the chlorine monitors. The licensee has made great strides in reducing the number of reportable events due to CRVIS actuations; however, the reliability of the chlorine monitors is still low. The improvement effort in this area has been protracted. This has resulted in the control room operators no longer trusting their chlorine monitor . Conclusions The assessment of this functional area indicates that management has not been effective in timely resolution of important issue Corporate management oversight of plant activities does not always ensure adequate involvement of the quality and engineering organizations in plant operations. When problems are identified by the quality and engineering organizations they are not always acted upon in a timely manne The licensee is considered to be in Performance Category 3 for an overall rating of the SALP area of quality programs and administrative controls affecting qualit . Board Recommendations Recommended NRC Actions Supplemental inspection effort should be devoted to this are Recommended Licensee Actions Increased corporate management involvement in site activities is recommended. In particular, additional corporate management involvement is needed to ensure that proper engineering and QA involvement is maintained in all activitie . o | |||
J. Licensing Activities Analysis During-the pre:,ent rating period, the licensee's management participated effectively in assuring the quality of submittals forlicensingactionsandinresponsestoNRCstaffrequest The licensee s reviews were generally timely, thorough, and technically sound. The licensee's participation was evident in the ATWS Rule (10 CFR 50.62) submittal which demonstrated that the licensee appeared to adequately understand staff policies and be able to make decisions based on adequate management involvement. The licensee's submittal contained all of the information that the staff requested for its revie An appropriate level of management was present and significantly involved at the review meeting held with the licensee, and the licensee's technical presentations were technically soun The licensee management was involved and responsive during the staff's review of WCNOC's request to remove the fire protection program from the Technical Specifications. This licensing action was the lead cause for generic technical specification improvements and involved rapidly evolving staff requirement Because WCN0C involved its management in this review, they were able to respond promptly to staff concerns to bring the review to completion. | |||
, | |||
The WCNOC management has generally exhibited an adequate understanding of the approach needed to resolve complex technical issues involved in licensing activities. WCNOC's June 16, 1987, submittal supporting analysis related to relaxed outage time and increased surveillance intervals demonstrated a clearunderstandingofthelicensingissuesinvolvedand followed the staff s guidance exactly as provided in the related generic documentatio The quality and level of detail of the licensee's safety evaluation summaries submitted pursuant to 10 CFR 50.59(b)(2) | |||
are not always adequate to permit the staff to conclude their acceptability. In some cases these summaries only provide a brief description of the change followed by a conclusive statement that the change does not generate an unreviewed safety or environmental question; they dn not provide a summary of the WCNOC safety evaluation that was prepared to support the chang In review of WCN0C's submittal related to their inservice testing program for pumps and valves, the staff met with the licensee on September 8 and 9. During the meetings the licensee agreed to revise their IST program in specific areas. However, WCNOC did not make a number of revisions in their March 2, 1987, Revision 6 resubmittal, as agreed to in the earlier meetin . _ _ _ _ _ _ _ _ | |||
. . . . | |||
The failure to follow up on the agreed upon technical resolution delayed the completion of the licensing action on the inservice testing progra The licensee had been generally responsive to NRC initiative during this rating period, with few longstanding regulatory issues being attributable to_the license On occasion, the licensee's response had not been adequate to permit the staff to resolve the technical issue without the need for additional interaction with the licensee. The staff's review of WCN0C's submittal related to the main steam line break outside of containment issue required multiple requests for additional information, and the licensee's responses to these requests were not expeditious. | |||
. | |||
The licensee reported 53 nonsecurity events to the NRC | |||
! | |||
operations center pursuant to 10 CFR 50.72. These events were almost always reported in a timely manne The licensee also submitted 49 nonsecurity Licensee Event Reports (LERs) during the reporting period. The LERs were well written and almost always timel There have been 8 LERs during this reporting period that have been caused by malfunctions or spurious actuations of the chlorine monitors. These LERs follow up on 18 previous LERs that have occurred since Wolf Creek was initially license This continuing series of LERs is indicative of a failure to identify the root cause of these failures and an ineffectual corrective action program for the chlorine monitor problem The plant has experienced seven unplanned scrams during this rating period. All of the scrams occurred during Cycle 2 which ended in September 1987. There were three Safety System Actuations, no Significant Events and five Safety System Failures during this rating perio . Conclusion The licensee continues to maintain a competent, knowledgeable | |||
' | |||
licensing staff; however, during this rating period there were occasional instances of lack of timely response to staff requests and a decline in content of summaries of safety evaluations submitted by the licensee in response to 10 CFR 50.5 The licensee is considered to be in Performance Category 2 in this are ______ . . | |||
27 Board Recommendation Recommended NRC Actions None Recommended Licensee Actions The licensee should improve the quality of the safety evaluation summaries submitted pursuant to 10 CFR 50.59 and should improve the content of licensing submittals to preclude the need for staff requests for additional-information that could have been foreseen by the license K. Training and Qualification Effectiveness Analysis The assessment of this functional area includes all activities relating to the effectiveness of tne training / retraining and qualifications program conducted by the licensee's staff. This area was inspected on a continuing basis by the resident inspectors. This area was also the subject of an inspection which was performed during the appraisal period to look into the training of both the licensed and nonlicensed staff. During the appraisal period, licensing examinations were administered by the NRC to seven (7) reactor operator (RO) candidates and to seven (7) senior reactor operator candidates. Five (5) of the R0 candidates and six (6) of the SR0 candidates passed the examinations and were subsequently issued licenses. The licensee currently has 36 individuals who hold an SR0 license and 15 individuals who have an R0 license. During the administration of the above examinations, the examiners found that the trainees had been adequately informed of the significant events that had occurred during the week of October 18, 1987. The trainees had also been schooled on the lessons learned from these event The inspections in the operator requalification training area indicate that the management oversight in this area has not been sufficiently thorough. This is evidenced by: | |||
The section of the procedure (ADM 06-224) on licensed operator requalification training which relaxed a requirement of 10 CFR 55 without Commission approval. | |||
. | |||
An operator who had failed the annual requalification | |||
' | |||
examination and was therefore reouired to enter into an l accelerated requalification program was allowed to continue j to stand watch and perform watch standing duties prior to his completion of the accelerated training. | |||

. . | |||
The required reactivity manipulations had not been completed in the 1985-1986 requalification cycle for at least six licensed individuals. The correction of this problem had not been formally addressed, but an informal effort by the simulator instructors is to track the performance of the manipulations by each licensed individua During 1986, at least nine licensed individuals had failed to review all of the emergency and off-normal procedures as required by the requalification program. The licensee | |||
; | |||
revised the appropriate procedure to specify the aff-normal and emergency procedures to be reviewe The procedures requested after the revision were also incomplete and the procedure had to be further revised at the prompting of the NRC inspector, The licensee had not provided procedures for irplementing the 10 CFR 55 rule change issued by the NRC on May 27, 198 The above examples are indicators that the training department arrangement had not provided the attention tc detail necessary ' | |||
to assure adequate oversight of this are There has also teen evidence of inattention to detail on the part of the training staf Examples of this are: | |||
* | |||
minor uncorrected errors in the lesson plans that were reviewed; failure to have lectures scheduled for 10 CFR Parts 2, 21, 50, and 55 in the operator requalification program; | |||
* | |||
failure to revise a procedure to reflect a new requirement instituted by a rule change; and | |||
* | |||
failure to delete a procedure requirement which was dropped by a ruie chang No deficiencies were identified in the area of training of the nonlicensed staff. The procedures and policies in this area were adequately stated and understood. Training records in this area were generally complete and well maintaine . Conclusions | |||

9 , INTRODUCTION The Systematic Assessment of Licensee Performance (SALP) program is an integrated NRC staff effort to collect available observations and data on a periodic basis and to evaluate licensee performance based upon this information. SALP is supplemental to normal regulatory processes used to ensure compliance with NRC rules and regulations. SALP is intended to be sufficiently diagnostic to provide a rational basis for allocating NRC resources and to provide meaningful guidance to the licensee's management to promote quality and safety of plant operatio An NRC SALP Board, composed of the staff members listed below, met on May 17, 1988, to review the collection of performance observations and data, and to assess licensee performance in accordance with the guidance in NRC Manual Chapter 0516, "Systematic Assessment of Licensee Performance." A summary of the guidance and evaluation criteria is provided in Section II of this repor This report is the SALP Board's assessment of the licensee's safety performance at Wolf Creek Generating Station for the period March 1, 1987, through March 31, 198 SALP Board for Wolf Creek Generating Station:
L. J. Callan, Director, Division of Reactor Projects, Region IV (chairman)
J. L. Milhoan, Director, Division of Reactor Safety, Region IV M. R. Knapp, Acting Director, Division of Reactor Safety and Safeguards, Region IV D. D.

Baer, Chief, Facilities Radiological Protection Section, Region IV W. M. McNeill, Reactor Engineer, Materials and Quality Programs Section, Region IV I CRITERIA Licensee performance was assessed in 11 selected functional area Functional areas normally represent areas significant to nuclear safety and the environmen Some functional areas may not be assessed because of
___ _____-_ _.-__ _
, ,
,
little or no licensee activities or lack of meaningful observation Special areas may be added to highlight significant observation One or more of the following evaluation criteria were used to assess each functional area: Management involvement and control in assuring qualit . Approach to the resolution of technical issues from a safety standpoin . Responsiveness to NRC initiative . Enforcement histor . Operational events (including response to, analysis of, and corrective actions for). Staffing (including management).
However, the SALP Board is not limited to these criteria and others may have been used where appropriat Based upon the SALP Board assessment, each functional area evaluated is classified into one of three performance categorie The definitions of these performance categories are:
Category 1. Reduced NRC attention may be appropriate. Licensee management attention and involvement are aggressive and oriented toward nuclear safety; licensee resources are ample and effectively used so that a high level of performance with respect to operational safety and construction quality is being achieve Category 2. NRC attention should be maintained at normal level Licensee management attention and involvement are evident and are concerned with nuclear safety; licensee resources are adequate and are reasonably effective so that satisfactory performance with respect to operational safety and construction quality is being achieve Category 3. Both NRC and licensee attention should be increase Licensee management attention or involvement is acceptable and considers nuclear safety, but weaknesses are evident; licensee resources appear to be strained or not effectively used so that minimally satisfactory performance with respect to operational safety and construction quality is being achieve ;

III. SUMMARY OF RESULTS The SALP Board review revealed areas of strength in fire protection and security with an increase in performance from the previous SALP perio Performance in the areas of emergency preparedness and surveillance remained consistent with the previous SALP period. All other areas revecled a decline in performance or a declining trend from the previous SALP period. The overall decrease in performance is due, in part, to the failure of licensee management to maintain effective control of major outage The licensee's performance is summarized in the table below, along with the performance categories from the previous SALP evaluation perio Previous Present Performance Category Performance Category Functional (02/1/86 to 02/28/87) (03/1/87 to 03/31/88) Plant Operations 2 2 Radiological Control 2 2 Maintenance 1 2 Surveillance 2 2 Fire Protection 2 1 Emergency Preparedness 2 2 Security 2 1 Outages 2 3 Quality Programs and 2 3 Administrative Controls Affecting Quality Licensing Activities 1 2 Training and Qualification 1 2 Effectiveness I PERFORMANCE ANALYSIS Plant Operations Analysis The assessment of this area consists chiefly of the activities of the licensee's operational staff (e.g., licensed operators and nuclear station operators). It is intended to be limited to

operating activities such as: plant startup, power operation, plant shutdown, and system lineup Thus, it includes activities such as reading and logging plant conditions, responding to off-normal conditions, manipulating the reactor and auxiliary controls, plant-wide housekeeping, and control room professionalis This area has been inspected on a continuing basis by the NRC resideist inspectors and on several occasions by NRC regional inspectors. Specific areas inspected included operational safety verifications, safety system walkdowns, follow up on significant events / problems, and review of licensee event reports (LERs).
One violation was identified in this functional area and, while it indicated additional management controls were needed, corrective action was promptly initiated by the licensee. Also, one of the escalated enforcement violations listed in the outage functional area included three examples of problems relating to the operations functional area. Four LERs were issued by the licensee in this functional area. These four LERs had no major effect on plant safety. One of the LERs concerned the one violation that was identified in this are The remaining three LERs were ali personnel errors and were indicative of a failure
,
to pay attention to detai Corrective actions initiated by licensee management included requiring the use of procedures in additional areas in operations. At the end of the SALP period the use of procedures in operations was much improve Operational events and NRC observations showed that operations interface with other departments is lacking. There has been an apparent failure of operations to make effective use of technical support groups. In some cases even when technical support groups became aware of problems and provided input to operations, the input was ignored or was lost. There are two examples. The first was when operations was not responsive to Nuclear Safety Engineering's information and advice concerning the essential service water (ESW) pipe-wall thinning issue. As a result, timely corrective action was needlessly delayed. The second was when engineering provided disposition to repair a section of thinwall safety related pipe and the disposition was misplaced for approximately 3 month In general, operator performance, as observed by the NRC
,
inspectors, has been good. Control room professionalism has l
'
been maintained and good operator morale exhibited. At times, however, the operators failed to pay attention to detai Two
- examples of this are given below
I t
_ _ _ _ _ _ _ _ . _
. .
The first example occurred when vital batteries were allowed to be depleted over a 30-hour time span without a procedure being available to provide alternate AC power to the battery chargers, and without bus voltage being observed carefully or without periodically observing current readings and comparing them to expected value The second example was the uncontrolled use of operator aids. When ESF actuations occurred as a result of the degraded batteries, the operators relied on the uncontrolled aids in determining that certain manual isolation valves were shut. The valves were, in fact, cpe When the valves had been opened, the uncontrolled aid had been forgotten. This resulted in the undesirable placing of lake water in each of the steam generator The licensee continues to give strong management support to the college degree program for operations personnel. The number of operators with engineering degrees or working toward degrees is considered to be a plu The number of operators with senior reactor operator licenses exceed the number of operators with reactor operator licenses by more than 2 to 1. This allows the licensee more versatility in the use of the operators, while at the same time giving operators additional training and mobilit In general, the licensee maintains a 6-shift rotation of their operating crew This allows for a better utilization of the crews, less overtime, and increased trainin . Conclusions The overall assessment of this area indicates that improvements need to be made. As stated in the previous SALP report, licensee attention to detail in this area can be improve The use of procedures in operations was noted to improve; however, this occurred only after the situation had been allowed to deteriorate to an unacceptable leve The examples of inattention to detail and the lack of effective operations interface with other departments reflects an ineffective management oversight in this functional are Staffing in this area is considered a strength, along with good control room professionalism during power operation The licensee is considered to be in Performance Category 2 in this area, with a declining tren _ _ _ _ _ _ _ - _

Radiological Controls Analysis The assessment of this functional area includes the following areas of activity which are evaluated as separate subareas to arrive at a consensus rating for this functional area:
(a) occupational radiation safety, which includes controls by licensees and contractors for occupational radiation protection, radioactive materials and contamination controls, radiological surveys and monitoring, and ALARA programs; (b) radioactive waste management, which includes processing and onsite storage of gaseous, liquid, and solid waste; (c) radiological effluent controls, which includes gaseous and liquid effluent controls and monitoring, offsite dose calculations and dose limits, radiological environmental monitoring, and the results of the NRC's confirmatory measurements program; (d) transportation of radioactive materials, which includes procurement and selection of packages, preparation for shipment, selection and control of shippers, delivery to carriers, receipt / acceptance of shipments by receiving facility, periodic maintenance of packagings and, for shipment of spent fuel, point of origin of safeguards activities; and (e) water chemistry controls, which includes primary and secondary systems affecting plant water chemistry, water chemistry control program and program implementation, chemistry facilities, equipment and procedures, and chemical analysis quality assuranc Nine inspections were performed in the area of radiological controls during the assessment period by Region-based radiation specialist inspector There were five violations and one deviation identified in this functional are _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ - _ _ _

a. Occupational Radiation Safety The licensee's programs for occupational radiation protection, radioactive material and contamination controls, radiological surveys and monitoring, and ALARA programs were inspected four times during the assessment period. Two inspections were conducted during normal plant operations, one inspection during a scheduled refueling outage, and one special inspection after the release of radioactive material to the local county landfil The licensee's exposure for 1986 was 142 person-rem compared to the national PWR average of 392 person-re During 1987, the licensee's person rem exposure was 124 compared to a national PWR of 376 person-re The size of the radiation protection staff was adequate to support plant operations. A low personnel turnover rate within the radiation protection group was experienced during the assessment perio The licensee's approach concerning the resolution of technical issues indicated their understanding of issues was generally apparen Acceptable resolutions were generally proposed in response to NRC initiative Those violations identified in the radiation protection program were an indication of a lack of management involvement in assuring quality and worker trainin The two concerns noted during the previous assessment period which included: (1) lack of steam generator mockup training and (2) lack of health physics supervisory personnel presence in the plant to oversee and evaluate ongoing radiation protection activities, had not been fully resolve The licensee had made changes in the position of radiation protection manager, an individual with limited experience and not qualified in accordance with Regulatory Guide was aupointed to the position. The licensee recently

I contracted a qualified individual to oversee and provide direction to the radiation protection program, l
b. Radioactive Waste Management The licensee's program involving processing and onsite storage of solid waste was inspected twice during the assessment period. One violation was identified. The l licensee released radioactive material as trash which was found and recovered from the local county sanitary landfil The licensee had reduced the volume of solidified waste generated by use of a portable

A review of gaseous and liquid releases indicates that offsite doses were well below Te:hnical Specification limits. Three concerns were identified relating to: (1) liquid effluent monitor setpoints, (2) condensate stora4e tank analyses, and (3) radiation monitor calibration' dat \ ,
The offsite radiological environmental ronitoring program was inspected once during the ac40sment period. No violations were identified. The radic,ogical environmental monitoring program is effectively managed from the licensee's corporate office and implemented by atation personnel. The working relationship between the two groups -

Maintenance Analysis TheassessmentofthisareaiM1udesalllicenseeandcontractor activitics associated with preventive or corrective maintenance of instrumentation and control equipment'and mechanical and electrical system This area was inspected on a continuing basis by the NRC resident inspectors and periodically by NRC regional inspector There were two violations identified in this area. These
'
violations involved the failure of the licensee to request a code ex.emption when required and three examples of a failure to (
follow precedures. There were 11 LERs issued by the licensee in this functional are One LER was due to inadequate pct-maintenance / testing or, a containment isolation valve, another LER was due to an accidental mispositioning of a breaker switch.
l l The escalated enforcement action that was taken due to the problems which occurred during the fall refueling outage revealed significant problems within the mainterance organization. These problems consisted of workers failing to follow procedures, inadequate proceduras, inadequate control over special processes, and an overs ' 5reakdown of management oversite of maintenance activities dunng the eefueling outage.

~/ During the last quarter of the SALP period, the maintenance management organization underwent significant changes Maintenance was combined with facilities and modificat. ions to form maintenance and modifications. This change combines all maintenance activities under a single manager. The superintendent of maintenance transferred to the outage plannin0 group and the manager of facilities modifications became the manager of maintenance and modifications. In addition, some lower level h.anagers were transferred and some positions were eliminated. These changes appear to have significantly strengthened the maintenance are . Conclusions The NRC found evidence of upper management support for a strong maintenance progra However, the implementation of this program was not adequately carried out. Management oversight of the day-to-day activities in the area of maintenance declined

inservice inspection activitie This functional area was inspected on a routine basis by the NRC
.
resident inspectors and periodically by NRC regional inspectors, t
The enforcement history in this functional area identified two violations during this assessment period. Also, several LERs were issued by the licensee during this assessment perio Personnel errors and inadequate procedures were the predominant causes of the violations and reportable events during this assessment period. This resulted in examples of missed surveillances, late performance of surveillances, inadequate post-test review, and undesirable engineered safety feature actuations which are similiar to problems which occurred during the previous SALP perio During the previous SALP period, the licensee was rated a SALP Category 2 in this functional area with a decreasing tren Although the enforcement and reporting history indicate improvement, as noted above, similar procedural and personnel errors are being repeated during this SALP perio . Conclusions The overall assessment for this functional area indicates a program for scheduling and tracking of surveillance activiG es that appears adequat Procedures in some cases did not address all Technical Specification surveillance requirements adequately. The repeat procedural and personnel errors indicate that additional management involvement is needei The licensee is considered to be in Performance Category 2 in this functional are __ - _ _

Also, additional management involvement with surveillance activities is encourage E. Fire Protection Analysis The assessment of this area includes routine housekeeping (combustibles, etc.) and fire protection / prevention program activities. Thus, it includes the storage of combustible material; fire brigade staffing and training; fire suppression system maintenance and operation; and those fire protection features provided for structures, systems, and components important to safe shutdow This area was inspected by a Region-based inspector and on a continuing basis by the NRC resident inspectors. During this assessment period the fire protection group went through some organizational changes. One change was the transfer of the fire protection training duties from the supervision of the fire protection engineer to the trainir.g department. The other change was the transfer of the fire protection group from the plant support organization to the operations organizatio The following observations were made:
. The licensee has made significant improvement in the area of administrative controls for fire barrier penetrations and opening Especially significant has been the reduction of missed fire watch patrol . Control of transient combustibles has been effectiv However, housekeeping could be improved in the area where trash is being deposited in other than approved containers (example: openings in tube steel).
. Fire brigade / watch training continued to be outstandin The transfer of the fire training group to the training department has shown no adverse effect . .
The licensee instituted a program to identify all fire barrier penetration seals that were either never sealed or removed and not resealed. This was an extensive program which the licensee aggressively pursued and complete . Conclusions The licensee has shown significant improvement in their fire protection / prevention progra Management involvement, both in the program as well as training, was evident. The major reason for the improvement in this area has been the continuing dedication and hard work of the well qualified fire protection engineer and training instructo The licensee is considered to be in Performance Category 1 in this are . Board Recommendations Recommended NRC Actions The level of NRC inspection in this functional area should be consistent with the minimum inspection program, Recommended Licensee Actions The licensee should assure that the recent organizational changes that have the fire protection engineer reporting to a different group and at a lower management level does not result in a reduction of management suppor F. Emergency Preparedness Analysis The assessment of this area inciudes the licensee's preparation for radiological emergencies and response to simulated emergencies (exercises). Thus, it includes emergency plan and implementing procedures; emergency facilities, equipment, instrumentation, and supplies; organization and management control; training; independent reviews / audits; and the licensee's ability to implement the emergency pla During the assessment period, four emergency preparedness inspections were conducted by Region-based and NRC contractor inspectors. One of these inspections was the observation and evaluation of an annual emergency response exercise by a team of
,
NRC and contracter inspectort. During the exercise, four l deficiencies from a previous exercise were closed and one new
!
deficiency was identified. The deficiency identified during the exercise involved incorrect classification of the emergency as l
l l
. .
an unusual event rather than an aler The licensee's overall performance during the exercise was evaluated as good. The NRC staff concluded that licensee emergency response personnel demonstrated their ability to protect the health and safety of the publi Three routine inspections resulted in identification of three violations. One violation involved failure to document required communication tests of the emergency response facilities. The other two violations, one of which was a repeat violation, involved tailure to determine availability of required emergency preparedness personnel in the event of an accident. Training was identified during the previous SALP period report as an area needing management attention. The licensee has developed lesson plans, revised training requirements, and implemented a more efficient record management syste The 1987 SALP report stated, "However, several changes were made to the onsite emergency planning administrator (EPA) position, and the replacement EPAs have had little previous experience in this area." Due to attrition, new inexperienced personnel have been assigned the onsite emergency planning and preparedness responsibilities. Discussions held with onsite management revealed a difference of opinion as to what the functions of the onsite emergency preparedness coordinator were and would be in the future. The offsite emergency preparedness administrator is located in Wichita, Kansas. The licensee ha; recently added another level of supervision above the EPA, removing the EPA further away from plant management. (This reorganization presently is awaiting NRR approval.) The emergency preparedness program appears to be in a trantition phase with the shift in lead responsibility for emergencf program to the corporate offic . Conclusions The violations issued in shift staffing and augmentation indicate that the personnel notification method and procedure requires additional improvement. Hansgement attention should be devoted tu meeting regulatory requirements and licensee commitment Licensee management attention and involvement are evident; licensee resources are adequate and reasonably effective so that
,
satisfactory performance with respect to operational safety and l construction quality is being achieved.

The inspection findings for this evaluation period indicate, overall, that the licensee's emergency preparedness program is adequate to protect the health and safety of the publi The licensee is considered to be in Performance Category 2 in this are . Board Recommendations Recommended NRC Actions NRC attention should be maintained at normal level Attention should be directed to licensee action taken toward correcting the call-out drill response and shift augmentation response time Recommended Licensee Actions The level of management attention to the implementation of the emergency preparedness program should be increased to ensure proper response to NRC identified concerns relating to call-out drill response and shift augmentation response times. The licensee should expedite correction of the call-out drill response and shift augmentation concer Management should review the distribution of onsite and offsite emergency program areas of a thority and responsibilitie G. Security Analysis The category of security relates to all activities whose purpose it is to ensure the protection of the plant. Specifically, it covers all aspects of the security program including ancillary efforts such as fitness for duty and access authorintion program Examples are: the licensee's overall management involvement ir, e-tablishing protective policies; designing physical security systems; submitting the security plan and implementing associated procedures; selecting, training, equipping, and supervising personnel; maintaining the hardware '
that suppcrts the program; and auditing and measuring the performance of the security progra This area was inspected on a continuing basis by the NRC resident inspectors and on a periodic basis by the NRC Region-based inspectors. Four inspections were conducted by Region-based NRC physical security inspectors during the assessment perio Four violations were identified, two by the licensee, f

There was evidence of prior planning and assignment of priorities. _ Policies and procedures are well stated, appropriately disseminated, and understandable. Decisionmaking was usually at a level that ensured adequate management revie The.new corporate structure, which includes a repositioning of the Quality Assurance Department, is committed to continuing an independent and effective oversight of security-related matter Management reviews of identified security ratters were timely, thorough, and technically sound. The init.a1 review of security incidents has improved and further examination for generic significance has been enhance Records were generally completo, well maintained, and available. Rarely were procedures and policies violated. However, ;ome cases of personnel failure have occurred and these appear to be associated with temporary employee hiring practices. Corrective action on licensee identified violations was generally effectiv A clear understanding of security issues was demonstrated and subsequent decisions reflected reasonable and prudent judgement on the part of management. These kinds of judgements were also demonstrated in the Training and Human Relations Departments where security's ancillary efforts, such as fitness for duty, continual observation of employee's behavior, and the access authorization programs were manage There has been a major organizational restructuring of the Quality Assurance (QA) Departmen The chanaes have been too recent to evaluate their impact on the herett fore strong security oversight effort. There is some concern that these changes will not provide the level of audit expertise previously provide A review of these changes and the quality of the audits performed will be necessary in the futur The licensee has been usually responsive to NRC initiatives, but there continues to be two long standing regulatory issues attributable to the licensee. These are control room access and alarm assessment capabilit Technically sound and acceptable resolutions were proposed initially in most cases, but timeliness of resolution for these outstanding issues is slo After considerable discussion, the licensee agreed that their CCTV system had degraded and proposed proper corrective action One major violation concerning security personnel attentiveness was directly attributable to a member of the security
, organization. It was promptly and effectively correcte A few l
minor procedural mistakes by security personnel have occurred,
'
but were not repetitive. These mistakes appear to be indicative
of a need to enhance the selection process for temporary l
security personnel and to be persistent in programmatic
'
training.
l t
_ _ _ _ _
+ .
Occasional computer outage related events, construction / outage worker misunderstandings of security requirements, and maintenance related activities were attributable causes to violations. These events were identified and reported in a timely manne Security organization positions were clearly identifie Authority and responsibility was clearly defined. This included the relationship with the rest of the corporate organization.- A new squad manning structure has allowed for training and practice in squad response tactics. Temporary contract personnel, while not meeting anticipated standards, have been utilized to staff appropriate watchperson billet However, the employment practices used for these temporary watchpersons, combined with their lower experience levels and abbreviated training, appear to have had some adverse impact on the security operation. It did accomplish the overall goal of providing relief for the more experienced offi ers and to make them available for more critical task . Conclusions The licensee appears to have an ample number of supervisors, fully qualified security officers, and support personnel assigned to the security department to comply with the several security plans. With the exception of a few minor procedural errors, the security force had operated at a high level of performanc The 'icensee management's attention and involvement with nuclear security is evident. Licensee resources were appropriate and effective so that there was very good performance with respect to site physical and personnel securit The licensee is considered to be -:, Performance Category 1 in this are . Board Recommendations Recommended NRC Actions The NRC inspection level of the security program should be consistent with the minimum inspection program, with some exceptions. Exceptions where a more expanded inspection effort is recommended include: licensee measures to enhance and maintain physical security systems; methods for selecting, training, equipping, posting and supervising security personnel; and changes to the QA function where audits are performed to measure the performance of the security program and its ancillary efforts.

19 Recommended Licensee Actions The licensee should continue to probe the causative factors of security events for broader implications and adjust programs, training, disciplinary actions, maintenance, and engineering responses appropriately. The organizational adjustments made in the QA area should be closely monitored to ensure that the high quality of the security oversight program continue H. Outage Analysis The assessment of this area includes all licensee and contractor activitiesassociatedwithmajoroutages. It includes refueling, outage management, major plant modifications, repairs or restoration to major components and all post-outage startJp testing of systems prior to return to servic This area was inspected on a continuing basis by the NRC resident insp:ctors, and periodically by NRC regional inspectors. In addition, an inspection was performed by a safety system outage modification inspection (SCOMI) team. The inspections included refueling activities, outo s management, planningandscheduling, staffing,majorcomp.mnts/ systems repairs and modification, and startup testin The licensee had two major outages during this SALP perio There was a refueling outage which lasted approximately 101 days and an outage to replace leaking reactor vessel 0-rings which lasted approximately 16 days. Refueling outage activities included replacement of Raychem splices, replacement of eroded essential service water pipe, annual inspection of the diesel generators, removai of heaters from Limitorque valve operators, replacement of reactor coolant pump "B" number one seal, replacement of the trip mechanism shafts on the reactor trip breakers, replacement of the tube bundle in the jacket water heat exchanger for diesel generator "A", rework of Valcor valve operators, cleaning of condenser tubes and inspections for thin wall pipes. There were numerous significant operational events which were attributable to causes under the licensee's control in this functional are There were four violations identified in this functional are Two of the violations involv.d escalated enforcement action and a proposed imposition of Civil Penalty. There were two LERs issued by the licensee in this functional area. The two LERs were on events that resulted in violations being issued.

. .
The two violations that resulted in escalated enforcement involved examples of procedural control weaknesses that the NRC considered significant. These weaknesses indicate management failed to provide an appropriate level of management oversight of safety-related activities. This is evidenced by the examples sited below as well as other areas in this repor Management oversight of outage activities was less than adequate as pointed out by the six examples of failure to follow procedures and four examples of inadequate procedures listed in the escalated enforcement packag The NRC staff was concerned with the licensee's lack of indepth analysis of these events. The licensee's ability to perform root cause analysis and implement timely and appropriate corrective actions was a noted weaknes During repair efforts on thin wall pipe due to erosion / corrosion the licensee experienced some difficulty. The licensee had on site a contractor workforce knowledgeable and experienced in the forming, fitting, rigging, and aligning of heavy pipe. The licensee decided to repair the thin wall pipe with their permanent maintenance workforc The maintenance workforce was not as experienced in this area as the contractor workforc This resulted in significant problems due to failure to follow procedures, failu.*e to follow work instructions, and failure to accomplish work activities by appropriately qualified personne Maintenance management failed to realize the scope of work was beyond their expertis The licensee was generally responsive to NRC concerns, however, there was a lack of aggressive response to identified problems prior to NRC involvement. The licensee's investigation of outage related events indicated a less than aggressive approach to the resolution of technical issues. The 0-ring outage, which was the second najor outage of the year, indicated that the licensee failed to control the 0-ring cleanli ess. The licensee decided to restart the plant after the first outage with known inner 0-ring leakag . Conclusions The licensee's ability to plan, manage, and maintain control over complex outage evolutions was inadequate and resulted in escalated enforcement action. The licensee apparently failed to beli 2 in and enforce strict procedural compliance. Aggressive management involvement to address problems that occurred during the outage was lackin The licensee is considered to be in Performance Category 3 in this are _j

21 Board Recommendations Recommended NRC Actions
_
. Supplemental NRC inspections should be performed prior to and during the next major outag Recommended Licensee Actions The licensee should ensure that lessons learned from the previous outages are identified and reviewed for program improvements. The results of this review should be incorporated into outage planning and contro I. Quality Programs and Administrative Controls Affecting Quality Analysis The assessment of this area includes all management control, verification and oversight activities which affect or assure the quality of plant activities, structures, systems, and component This area may be viewed as a comprehensive management system for controlling the quality of verification activities that confirm that the work was performed correctl The evaluation of the effectiveness of the quality assurance system is based on the results of management actions to ensure that necessary people, procedures, facilities, and materials are provided and used during the operation of the nuclear power plant. Principal emphasis is given to evaluation of the
, effectiveness and involvement of management in establishing and assuring the effective implementation of the quality assurance prograa along with evaluation of the history of licensee performance in the key areas of: committee activities, design and procurement control, control of design change processes, inspections, audits, corrective action systems, and record In order to more clearly define the specific strengths and weaknesses noted in this functional area, the analysis is divided into three areas, as discussed below:
f Engineering l
,
! This area has been inspected on a routine basis by the NRC l resident inspectors and by a SSOMI team inspection during ( the assessment period.
I The staffing in the engineering area is generally adequate in terms of numbers, but it is weak in experience and training. Further, the weaknesses identified by the 550MI inspection are indications that the communications between the plant operating staff and the engineering organizations l
. .
were poo In one case, engineering made a change to the cooling system for an electrical equipment room,.which required manual adjustment of a flow control valve to adjust the temperature. Since the temperature in this room was required to be maintained within a relatively narrow range, a surveillance program to ve-ify the temperature should have been instituted but was not. As a consequence, the qualified life or performance of the equipment may have been affecte In another instance, it appeared that the operating staff failed to ask for engineering guidance when performing a maintenance activity that resulted in a deep discharge of the safety-related station batteries and disablement of the vital AC buses at the same time. This in turn led to the introduction of lake water into the secondary side of the steam generator The S50MI report includes a concern that appears to be largely attributable to engineering since it involved a failure to properly evaluate the effect of a temporary modification. The modification involved application of a clamp to keep a safety-related damper in the control room emergency ventilation system open. Had actuation of the damper been required, an operator would have had to remove the clamp. The application of the clamp in such a manner violated the intent of the Technical Specification for system operabilit There were also three LERs that were at least in part attributable to engineering activitie In each case, the LERs became necessary because there were errors in design documents such as drawings, specifications, and instrument set point dat b. Quality Assurance This area has been inspected by both the NRC resident inspectors and regional inspectors. In addition, the SSOMI team inspected the areas of procurement, material storage, and audit activitie There were two violations in the areas of procurement and of material receipt. Additionally, some of the problems in the management of the outage were related to Q The licensee had received, accepted, and installed a noncode part which formed a portion of the reactor coolant system boundar An audit after the plant restarted disclosed this, and subsequent waiver to the code was granted.

,
The reactor vessel head 0-rin'g seals were not correctly inspected prior to installation. Although this was not the major contributor to the 0 ring leak, it showed a tendency for quality performance to be at pro forma leve During the outage, there were problems with the weld repairs to the essential service water systems. The'e problems included the issue of inappropriate welding materials and welders making welds for which they were not qualified. These problems were uncovered by quality checks, but the investigation revealed that QA had missed several opportunities to identify the problems earlie The licensee's vendor audit program did identify a problem with the certification of fuses purchased from a supplie lhe licensee reported the facts to the NRC. Follow up action by the NRC resulted in the issue of an Information Notic The licensee had not conducted training in root cause determination. Corrective actions tended to be focused on specific events and did not often probe for the underlying cause For example, when a four-way valve on the MSIV actuator failed, the original root cause deter.nination was not correct. The redesigned valve subsequently faile When incorrect fasteners were found in the charging pump check valve, they were replaced. No determination was made as to whether the problem was the fault of the fastener or the valve manufacture c. Management and Administrative Controls This area has been inspected on a routine basis by NRC resident inspectors and regional inspector During this SALP period, the licensee realized the existence of problems with safety-related pipe wall thinning. NRC had two basic concerns with this issue. The first concern was that the short term operability determination of the thin wall pipe was not technically sound in that it was made by plant management without input from engineerin Management did not reassess system operability even after engineering made the determination that the pipe did not meet code requirements. Plant management communications with engineering was not adequate. The second concern was with long term corrective actions. Plant management's narrow focus on the issue of short-term operability showed that their understanding of the issue was lacking. The question of generic application of one thin wall pipe to other areas in the plant was not addressed in a timely manner. It was not until these i

.- .-
issues were raised by Nuclear Safety Engineering and the Nuclear Safety Review Committee that appropriate corrective actions were begun. The operational response to this problem was not timely and lacked thoroughness. The above is one example of a lack of management involvement in assuring quality. Other examples have been cited in other SALP area The enforcement history in the area includes seven violations and no deviations. Four violations were related to the environmental qualification of equipment. Ten LERs were issued by the licensee in this area. Eight of these LERs were related to control room ventilation isolation system (CRVIS) actuations. Six of these were due to problems with the chlorine monitors. The licensee has made great strides in reducing the number of reportable events due to CRVIS actuations; however, the reliability of the chlorine monitors is still low. The improvement effort in this area has been protracted. This has resulted in the control room operators no longer trusting their chlorine monitor . Conclusions The assessment of this functional area indicates that management has not been effective in timely resolution of important issue Corporate management oversight of plant activities does not always ensure adequate involvement of the quality and engineering organizations in plant operations. When problems are identified by the quality and engineering organizations they are not always acted upon in a timely manne The licensee is considered to be in Performance Category 3 for an overall rating of the SALP area of quality programs and administrative controls affecting qualit . Board Recommendations Recommended NRC Actions Supplemental inspection effort should be devoted to this are Recommended Licensee Actions Increased corporate management involvement in site activities is recommended. In particular, additional corporate management involvement is needed to ensure that proper engineering and QA involvement is maintained in all activitie . o
J. Licensing Activities Analysis During-the pre:,ent rating period, the licensee's management participated effectively in assuring the quality of submittals forlicensingactionsandinresponsestoNRCstaffrequest The licensee s reviews were generally timely, thorough, and technically sound. The licensee's participation was evident in the ATWS Rule (10 CFR 50.62) submittal which demonstrated that the licensee appeared to adequately understand staff policies and be able to make decisions based on adequate management involvement. The licensee's submittal contained all of the information that the staff requested for its revie An appropriate level of management was present and significantly involved at the review meeting held with the licensee, and the licensee's technical presentations were technically soun The licensee management was involved and responsive during the staff's review of WCNOC's request to remove the fire protection program from the Technical Specifications. This licensing action was the lead cause for generic technical specification improvements and involved rapidly evolving staff requirement Because WCN0C involved its management in this review, they were able to respond promptly to staff concerns to bring the review to completion.
,
The WCNOC management has generally exhibited an adequate understanding of the approach needed to resolve complex technical issues involved in licensing activities. WCNOC's June 16, 1987, submittal supporting analysis related to relaxed outage time and increased surveillance intervals demonstrated a clearunderstandingofthelicensingissuesinvolvedand followed the staff s guidance exactly as provided in the related generic documentatio The quality and level of detail of the licensee's safety evaluation summaries submitted pursuant to 10 CFR 50.59(b)(2)
are not always adequate to permit the staff to conclude their acceptability. In some cases these summaries only provide a brief description of the change followed by a conclusive statement that the change does not generate an unreviewed safety or environmental question; they dn not provide a summary of the WCNOC safety evaluation that was prepared to support the chang In review of WCN0C's submittal related to their inservice testing program for pumps and valves, the staff met with the licensee on September 8 and 9. During the meetings the licensee agreed to revise their IST program in specific areas. However, WCNOC did not make a number of revisions in their March 2, 1987, Revision 6 resubmittal, as agreed to in the earlier meetin . _ _ _ _ _ _ _ _
. . . .
The failure to follow up on the agreed upon technical resolution delayed the completion of the licensing action on the inservice testing progra The licensee had been generally responsive to NRC initiative during this rating period, with few longstanding regulatory issues being attributable to_the license On occasion, the licensee's response had not been adequate to permit the staff to resolve the technical issue without the need for additional interaction with the licensee. The staff's review of WCN0C's submittal related to the main steam line break outside of containment issue required multiple requests for additional information, and the licensee's responses to these requests were not expeditious.
.
The licensee reported 53 nonsecurity events to the NRC
!
operations center pursuant to 10 CFR 50.72. These events were almost always reported in a timely manne The licensee also submitted 49 nonsecurity Licensee Event Reports (LERs) during the reporting period. The LERs were well written and almost always timel There have been 8 LERs during this reporting period that have been caused by malfunctions or spurious actuations of the chlorine monitors. These LERs follow up on 18 previous LERs that have occurred since Wolf Creek was initially license This continuing series of LERs is indicative of a failure to identify the root cause of these failures and an ineffectual corrective action program for the chlorine monitor problem The plant has experienced seven unplanned scrams during this rating period. All of the scrams occurred during Cycle 2 which ended in September 1987. There were three Safety System Actuations, no Significant Events and five Safety System Failures during this rating perio . Conclusion The licensee continues to maintain a competent, knowledgeable
'
licensing staff; however, during this rating period there were occasional instances of lack of timely response to staff requests and a decline in content of summaries of safety evaluations submitted by the licensee in response to 10 CFR 50.5 The licensee is considered to be in Performance Category 2 in this are ______ . .
27 Board Recommendation Recommended NRC Actions None Recommended Licensee Actions The licensee should improve the quality of the safety evaluation summaries submitted pursuant to 10 CFR 50.59 and should improve the content of licensing submittals to preclude the need for staff requests for additional-information that could have been foreseen by the license K. Training and Qualification Effectiveness Analysis The assessment of this functional area includes all activities relating to the effectiveness of tne training / retraining and qualifications program conducted by the licensee's staff. This area was inspected on a continuing basis by the resident inspectors. This area was also the subject of an inspection which was performed during the appraisal period to look into the training of both the licensed and nonlicensed staff. During the appraisal period, licensing examinations were administered by the NRC to seven (7) reactor operator (RO) candidates and to seven (7) senior reactor operator candidates. Five (5) of the R0 candidates and six (6) of the SR0 candidates passed the examinations and were subsequently issued licenses. The licensee currently has 36 individuals who hold an SR0 license and 15 individuals who have an R0 license. During the administration of the above examinations, the examiners found that the trainees had been adequately informed of the significant events that had occurred during the week of October 18, 1987. The trainees had also been schooled on the lessons learned from these event The inspections in the operator requalification training area indicate that the management oversight in this area has not been sufficiently thorough. This is evidenced by:
The section of the procedure (ADM 06-224) on licensed operator requalification training which relaxed a requirement of 10 CFR 55 without Commission approval.
.
An operator who had failed the annual requalification
'
examination and was therefore reouired to enter into an l accelerated requalification program was allowed to continue j to stand watch and perform watch standing duties prior to his completion of the accelerated training.

. .
The required reactivity manipulations had not been completed in the 1985-1986 requalification cycle for at least six licensed individuals. The correction of this problem had not been formally addressed, but an informal effort by the simulator instructors is to track the performance of the manipulations by each licensed individua During 1986, at least nine licensed individuals had failed to review all of the emergency and off-normal procedures as required by the requalification program. The licensee
revised the appropriate procedure to specify the aff-normal and emergency procedures to be reviewe The procedures requested after the revision were also incomplete and the procedure had to be further revised at the prompting of the NRC inspector, The licensee had not provided procedures for irplementing the 10 CFR 55 rule change issued by the NRC on May 27, 198 The above examples are indicators that the training department arrangement had not provided the attention tc detail necessary '
to assure adequate oversight of this are There has also teen evidence of inattention to detail on the part of the training staf Examples of this are:
minor uncorrected errors in the lesson plans that were reviewed; failure to have lectures scheduled for 10 CFR Parts 2, 21, 50, and 55 in the operator requalification program;
failure to revise a procedure to reflect a new requirement instituted by a rule change; and
failure to delete a procedure requirement which was dropped by a ruie chang No deficiencies were identified in the area of training of the nonlicensed staff. The procedures and policies in this area were adequately stated and understood. Training records in this area were generally complete and well maintaine . Conclusions
,
The initial training of licensed operators and the training of
