I On September 16, 1988, the plant shut down and entered the fourth refueling outage. Major work activities in the outage included core reload, eddy current examination of 100 percent of the steam generator tubes, tube plugging, equipment qualification upgrades, a containment integrated leak rate test, inservice inspection; and valve packing replacemen The outage exceeded the planned schedule of 75 days by 28 day The nue. lear operations division was consolidated by relocating the vice president nuclear operations and the corporate staff to the V.C. Summer plant in the last quarter of 1987. The division underwent a reorganization in the first quarter of 1988 to reduce the number of management and supervisory levels. The relocation moves were supported by constructing new administrative and support facilities and upgrading existing one Direct Inspection and Review Activities During the assessment period, routine inspections were performed at the V. C. Summer facility by the NRC staff. Special team inspections were conducted as follows:
-
Equipment Qualification inspections were conducted in October 1987 and January 1988, with a follow-up inspection conducted in October 198 Operational Safety Team Inspection was conducted in November and December 198 II. SUMMARY OF RESULTS Summer was operated in an overall safe manner during the assessment period. Strengths were identified in the areas of Radiological Controls, Maintenance and Surveillance. A significant decline in performance that requires additional managerial attention was identified in the area of Securit Operations performance was mixe Strengths were noted in training of shifts as a team and the presence of a shift engineer / shift technical advisor on each shift to coordinate shift activities with other areas and thereby permit the shift supervisor to concentrate on safe plant operatio The establishment of the University of Maryland program to obtain degrees for on shift operators represents a substantive management connitment to improved shift expertise and safety. Corporate interest and oversight of plant activities was very apparent. However, the use of procedures containing errors, the failure to maintain control room drawings, and the lack of acceptable system configuration control at all times indicated a need for management attentio Added management attention is also needed to reduce the number of reactor trips. The fire protection area requires additional oversight to preclude repetitious errors that have occurred during this perio __

The Radiological Controls area was considered a strength. The reduction of contaminated areas to less than one percent was noteworthy. However, considering the current problems associated with steam generator tube integrity and failed fuel, the licensee is faced with challenges that may require innovative approaches if personnel exposure and contamination is to be maintained as low as reasonably achievable (ALARA).
The maintenance / surveillance program was well implemented and considered a strength. The reduction in maintenance work order backlog, implementation of a predictive maintenance program, and operations support to the planning and scheduling group are considered strengths. The timely completion of surveillance tests indicates that the testing program was well staffed and supervise Emergency Preparedness activities' were conducted in an adequate manne In the area of Emergency Preparedness, the licensee demonstrated an ability to adequately implement the essential elements of their Emergency Plan. However, inspection results showed that a weakness identified in the training of key staff personnel during the previous assessment still existe The Security area, long considered a strength at this site, experienced several significant problems which resulted in escalated enforcement late in the assessment period. Organizational changes in 1988 resulted in deteriorating security force performance. Management was slow to recognize these changes until personnal performance had decreased to a marginal level. Significant management attention is required to raise the performance of this area back to its past level of performanc The Engineering / Technical Support function was performed well during the evaluation period. The engineering staff was consolidated and relocated to the plant site to provide more rapid response to plant problem However, during the assessment period instances of ina6quate engineering evaluations and a concern with the adequacy of review of contractor evaluations were identified. The system engineer program which was established in late 1987 has been slow in being implemented. Additional management attention may be required to achieve the desired benefits of this progra The Safety Assessment / Quality Verification area performance was goo .0perations, engineering and management involvement in safety issues was apparent. The licensee continued to pursue and realize positive benefits from their efforts in safety system functional inspections and development of system design bases documents. In response to the excessive reactor trip problem, a root cause identification training program has been started. Repetitious trips from the main control board reactor trip switch in 1988 indicate a need for additional management attention in this i area.

CRITERIA
!
Licensee performance is assessed in selected functional areas.- depending on whether the facility is in a construction or operational phas 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 The following evaluation criteria were used, as applicable, to assess each functional area:
1. - Assurance of quality, including management involvement and control; Approach to the resolution of technical issues from a safety standpoint; Responsiveness to NRC initiatives; Enforcement history; Operational and construction events (including the response, analyses, reporting, and corrective actions); Staffing (includingmanagement);and Effectiveness of training and qualification progra However, the NRC is not limited to these criteria and others may have been used where appropriat On the basis of the NRC assessment, each functional area evaluated is rated according to three performance categories. The definitions of these performance categories.are as follows: )
Category Licensee management attention and involvement are readily evident and place emphasis on superior performance of nuclear safety or safeguards activities, with the resulting performance substantially exceeding regulatory requirement Licensee resources are ample and

effectively used so that a high level of plant and personnel performance is being achieved. Reduced NRC attention may be appropriat Category Licensee management attention to and involvement in the performance of nuclear safety or safeguards activities are good. The licensee has attained a level of performance above that needed to meet regulatory requirements. Licensee resources are adequate and reasonably allocated so that good plant and personnel performance is being achieve NRC attention may be maintained at normal level Category Licensee management attention to and involvement in the performance of nuclear safety or safeguards activities are not sufficien The licensee's performance does not significantly exceed that needed to meet minimal regulatory requirements. Licensee resources appear to be strained or not effectively used. NRC attention should be increased above normal level The SALP Board may also include an appraisal of the performance trend of a functional area. This performance trend will only be used when both a definite trend of performance within the evaluation period is discernable and the Board believes that continuation of the trend may result in a change of performance leve The trend, if used, is defined as:
Improving: Licensee performance was determined to be improving near the close of the assessment perio Declining: Licensee performance was determined to be declining near the close of the assessment period and the licensee had not taken meaningful steps to address this patter IV. PERFORMANCE ANALYSIS Plant Operations Analysis During the assessment period routine and special inspections were performed by the NRC staff. The fire protection program was examined by a special inspect ton in February,1988 and an Operational Safety Team Inspection (OSTI) was conducted in November and December, 198 The operations group is well staffed with five shifts that stand 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> watches.

8 The shifts train and operate together as a team. The shif t engineer coordinates all shift support functions and thereby frees the shift supervisor to concentrate on safe plant operation. The reactor operators and first and second assistant operators routinely rotate from the control room to auxiliary operator watch stations to maintain their proficiency and utilize their experience throughout the plant. The licensee has experienced only negligible personnel turnover .n this are To improve educational and engineering . expertise on shift, management initiated a college degree program for licensed operators in 1987. This program is conducted by the University of Maryland and offers a Bachelor of Science degree in Nuclear Scienc Thirty-two of the forty initial candidates are still i participating in the program. Any nuclear operations personnel may participate. in this program; however, licensed operators and license candidates are given priorit Administrative controls to ensure control room professionalism were established and are effective. Access to the at-the-control area is limited and well controlle Operator logs were legible and complete with normal conditions, off-normal conditions, special tests and events identifie Preshift briefings were conducted and shift turnover forms were used by all operators. Watchstanders and duty technician assignments were clearly posted in the control roo Key controls for operator access to spaces and equipment were well organize Operator response to off-normal conditions and plant transients was prompt and thorough. This was exemplified during a loss of reactor coolant letdown event that occured in 1988. The rapid identification of an incorrect control signal resulted in the operator transferring centrol of letdown from the main control board to the remote shutdown panel and thereby bypassing the faulty control circuit. This timely response prevented a plant shutdown. The licensee has initiated a program to enhance the black board concept for alarm annunciator The OSTI identified instances where additional licensee attention was needed to control valve and circuit breaker alignment limiting conditions for operation ( LCO) , and legibility of control room essential drawings. The licensee was very responsive in revising LCO procedures to reduce the potential for reliance on inoperable systems and incorporating procedural steps to require independent verification of valve and circuit breaker position System walkdowns by the OSTI team members identified numerous technical and typographical errors in existing system operating procedures and attachments used for valve and breaker alignment These procedures had been implemented and issued to the field for use, ,
without a good review, or validation. Operators had to make the needed corrections while accomplishing system lineups and verification of lineups. One illegible drawing was identified 1_ ____ _

i during the OSTI inspection; a resulting followup review by the 'l licensee identified 28 ~ additional drawings with inadequate or marginal clarity. These items were the subject of violation j l belo Over the assessment period, plant housekeeping was considered average. The control room and main control board were repainted and new carpet was installed during the 1983 refueling outag In general plant areas, a program to upgrade painting, appearance and protective coatings has resulted in an ' improved appearanc However, it is noted that the number of leaks from non-radioactive and radioactive systems, although wrapped with herculite and routed to drains, have . increase Operation should pursue the timely correction of these deficiencie Regular plant tours are accomplished by the Vice president Nuclear Operations, the plant manager and the plant ranager's staf Corporate interest and oversight of the plant was evident from frequent visits and plant tours by senior managemen Monthly trend reports and performance indicators are published to keep plant and corporate management appraised of plant status and potential plant.probl' em The plant capacity factor for the SALP period was 72.4 percent even with a 103 day refueling outage at the end of 1988. A comparison with the previous SALP shows that the unit forced outage rate increased from 4.01 to 6.20 percen The outage rate-is above the industry mid 1988 one year median of 4.8. The reactor trips, when compared with the previous SALP increased from seven to eight. The trip rate, even though some improve-ment was shown in 1988, is still above the industry one year median of approximately two. A review of the reactor trips
'
determined that four trips were related to equipment failure, two trips were due to equipment design and two trips were the result of personnel errors. Five of eight trips occurred during the performance of surveillance test Management responded to the excessive reactor trip problem by initiating actions to improve labelling of procedural steps that present trip hazards and providing dditional technical training on surveillar.ce tests which expose the unit to high trip ris l Studies are <:urrently underway to justify a reduction in periodicity of high trip potential surveillanc The adequacy of the licensee's post trip reviews was questioned in May 1988 as the result of a reactor trip and reduced service water flow to the reactor building cooling units during a subsequent safety injectio The reduced service water flow problem was not detected during the post trip review. The

I diligence of the Independent Safety Evaluation Group resulted in the identification of this problem after the plant restarte This item was the subject of a severity level III violation 3 i
issued in August 198 (See violation a. below).
A problem was identified on the previous SALP concerning the correct alignment of swing pumps. The corrective actions taken and discussed in the previous SALP appeared to be effective and no new or repeat problems were identified in this are Control of combustible and flammable materials in safety related related areas of the plant was considered good. An identified exception included an area in the auxiliary building where approximately 4.5 tons of combustible charcoal had been temporarily store (See violation g below).
The required drills and training of Fire Brigade members were conducted within the frequency outlined in plant procedure Satisfactory performance of the Fire Brigade in an unannounced drill witnessed by NRC staff demonstrated the effectiveness of the Fire Brigade training progra The licensee has experienced events where compensatory fire watches were not established for degraded fire barriers or inoperable fire e These events were the subject of five violations (quipmen c through g) and five LER's during the evaluation period. Extensive management attention was directed to this area. A Fire Protection Officer was placed on each operating shift to monitor and provide improved response for degraded fire barriers and protection equipment. This single point accountability had additionally resulted in improved communications and better equipment status contro Staffing in the fire protection area increased in 1988 from a fire protection supervisor and five technicians to a fire i protection supervisor; a fire protection coordinator; two specialists who supervise fire protection officers and surveillance testing; three technicians and five operation shift fire protection officer These changes occurred in the last quarter of 1988 and have not been implemented long enough to allow full evaluatio Seven violations were identified of which five involved inadequate fire protection or compensatory actions.

I Category: 2 Previous rating - Operation: 2 Fire Protection: 2 Recommendations:
Management support of operations needs to be improve This need is indicated by procedures being issued that still contain errors that should have been identified by a procedure review / verification program. Another indication is control room drawings issued for operations use when numerous drawings were illegibl Operations personnel need to be more aggressive in raising these type problems to management's attention and in pursuing a satisfactory resolution of identified problem B. Radiological Controls Analysis During the assessment period, inspections were performed by the resident and regional inspection staff Inspections were conducted in the areas of radiation protection, radiological '
effluents, and confirmatory measurement During the assessment period, the licensee reorganized the chemistry and Health Physics departments in the first quarter of 198 A chemistry and health physics manager position was established and filled with a former corporate health physicis _ _ _ _ . - - _ _ _ _ - - _ _ . _ . .

The smaller-permanent staff has not had any deleterious' effects on the performance of the HP staf Tha knowledge'and experience
' level' off the HP- staff were excellent. The overall quality of the staff was a program strengt Radiation protection training was considered good. .Th licensee's general, employee training in radition protection was well defined. The licensee enhanced training by establishing a training program for HP supervisors. 'Since this program is in addition to regulatory requirements, it -indicates management's support for and commitment to high training standard Management support and involvement in . matters related to radiation protection were demonstrated by upgrading the whole body counters with germanium detectors and the procurement;of a standup whole body counter. . Inspection during the evaluation period indicated that the . radiation protection program received strong support from other plant department At the.end of 1988, the contaminated area of the plant was less than one percent of the total . areas monitored. Ma licensee's aggressive -contamination control program allows plant personnel to . access containment without protective clothing. Resulting benefits are a reduction in the amount of radioactive waste generated and less restrictions on workers and supervisors during performance of their assigned task In 1987, the collective dose was 562 person-rem with 547 person-rem being attributed to a refueling outage and maintenance on steam generators. In 1986, the collective dose was'23 person-rem, however, there were no outages in 1986. In 1988, the licensee expended 18 person-rem for normal operations and 503 person-rem for outage related wor Primary contributors to the high collective dose in the last two years have been the increase in reactor coolant system (RCS)
radioactivity and increased steam generator maintenanc In some high traffic areas of the plant radiation in the residual heat removal-(RHR) lines has caused dose rates in adjacent areas to increase by a factor of 2 Significant increases in dose rates'were also observed during reactor head work, fuel movement

-e 13 and reactor cavity decontamination. The collective doses' for 1987 and 1988 are representative for plants experiencing steam generator and fuel problem .The licensee has a number of initiatives underway to limit and reduce dose rates within the plant including elimination of the resistance temperature detector bypass- manifold, evaluation of the replacement of primary system filters with smaller mesh filters to reduce the particulate in the RCS, evaluation of raising the pH of the RCS, and chemical decon of various RHR/RCS-systems and/or components in 198 The licensee's respiratory protection and radiation work permit programs .were found to be satisfactor The licensee experienced a total of 130 personnel contaminations in 1987, l 76 skin contaminations and 54 clothing contaminations. In 1988, the number of personnel contaminations increased 240 percent to 141 skin and 171 clothing contamination The licensee experienced 52 discrete radioactive particle contaminations in 1988, due' to failed fuel and the increased amount of system-maintenanc Previously, the licensee had only three hot particle contaminations with the majority of the particles being fission products. The licensee has an aggressive program for the identification and control of discrete radioactive particle During the assessment period, the licensee contracted with a vendor to perform super compaction of dry radioactive waste to reduce the volume of dry radioactive waste shipped to a low level waste burial facilit Participation in the NRC spiked sample analysis program for beta emitting radionuclides showed agreement with NRC results for all four nuclide Liquid and gaseous effluents were within regulatory limits for concentrations of radioactive material releases. There were slightly increasing trends in the annual quantities of radioactive material effluent releases for the past three year Annual effluent releases are summarized in the Supporting Data L
and Summaries,Section V.K. Licensee estimates of doses to

Equipment Qualification (EQ)
team inspections were conducted in October 1987, January 1988, and October 1988. A Containment Integra.ted Leak Rate Test (CILRT) inspection was conducted in September, 1988. An OSTI in November and December 1988, evaluated maintenance support of operation The maintenance organization is adequately staffed and trained to support operation of the plant. The staff is supplemented by contractors, as needed, to support plant outages. This unit has experienced a very low turnover of maintenance personne The corrective maintenance and preventive program was planned and performed in accordance with established procedure Supervisors provided adequate direction and assistance, as needed, to complete activities. QC provided adequate coverage of safety related activitie Maintenance activities were scheduled and tracked with a history maintained by computerized system The predictive maintenance program used vibration analysis, temperature monitoring, ferrography (lube oil), infrared surveys and motor operated valve analysis and tests systems (M0 VATS) to determine the need for equipment maintenance. Success experienced in this program included vibration monitoring of the main feed pumps which led to early identification and correction of coupling grease loss and alignment problems. The use of vibration analysis and ferrography on the reactor coolant pumps (RCP) permitted the licensee to extend the scheduled maintenance on "B" RCP to refueling outage This extension will allow concurrent motor tear down and seaI replacement on the RCP's for

17 Performance Rating Category: 1 Previous rating - Maintenance: 1 Surveillance: 1 Recommendations D. Emergency Preparedness Analysis The inspections conducted during this assessment period by NRC staff included one routine EP inspection in M6y 1988, and an Emergency Response Facility (ERF) Appraisal conducted in March 198 Based on the inspection activity noted above, the licensee demonstrated an ability to adequately implement the essential ;
elements of the Summer Emergency Plan during a simulated or
'
actual emergency event. However, declining performance in the area of Emergency Plan required trair.ing was identified as noted !
belo The routine inspection, conducted in May 1988, disclosed a recurrent licensee problem involving the failure to follow their Emergency Plan with re. sect to requirements for training. A violation was identifieo for failure to provide required training to two key members (Radiological Assessment Supervisor and Maintenance Supervisor) of the onsite emergency organization assessment staff in accordance with Emergency Plan procedure The licensee's planned corrective action appeared adequate. All other training of key members of the emergency organization appeared to be consistent with approved procedures. However, a similar violation was identified during the preceding assessment period involving training of key members of the emergency organization on the fission product barrier approach to emergency event classificatio During the ERF Appraisal walkthroughs, a Shift Supervisor made an untimely event classification, as well as an incorrect emergency declaration in response to a postulated casualty presented by the inspector. It was noted that an artificiality in the scenario may have been a contributing factor. However, the licensee acknowledged that improvements were needed in the Emergency Plan training program. The General Manager for Operations connitted to provide additional training for Emergency Directors to include, as a minimum, event classification and protective action recommendation The March 1988 ERF Appraisal disclosed that the emergency i response facilities, including the Control Room, Technical
'
Support Center (TSC), and Emergency Operations Facility (EOF),
fully met the regulatory criteria, orders, and license

conditions issued to implement Supplement 1 to NUREG-0737. The ERFs provided all necessary equipment, systems, documents, and supplies to assist the licensee in the identification and 1 mitigation of plant emergency events, and implemented all elements of the Emergency Plan required to protect onsite personnel and the public within the assigned emergency planning zon The licensee maintains the ERFs, and all equipment and systems 4 therein, in an adequate state of operational readiness for responding to emergencies.. The licensee also established an effective management and control program fer the Early Warning Siren System, and installed a redundant transmitter and encoder for the . system. Shift staffing augmentation appeared to be ;
i consistent with regulatory requirements and guidance. Although no violations were identified during the Appraisal, the licensee committed to review several dose assessment followup items and to provide a response. The licensee's response has been reviewed and determined to be acceptabl During the assessment period, five revisions were submitted to
'the Emergency Plan for NRC review and approva The proposed revisions were determined to be consistent with regulatory requirements and guidanc One violation was identified. Although the finding was not indicative of a significant programmatic breakdown in the EP program as a whole, it is clear that performance in Emergency Plan required training has declined. The licensee continued to demonstrate overall the capability to fully implement key elements of the Emergency Plan during simulated or actual plant emergency event Severity Level IV violation for failure of two key members of the onsite emergency response organization to complete training in accordance with Emergency Plan Procedure EPP-018, Emergency Training and Drill (395/87-23)
2. Performance Rating Category: 2 Previous rating: 2 3. Recommendations The Board note: that during an inspection after the close of the assessment period (in January 1989) there was another finding of failure to provide training to members of the emergency response tea We encouragt. licensee management to give increased emphasis to emergency response training and retraining and recommend increased NRC inspection resources be provided in this area.

and providing additional protection for the secondary power supply syste Historically, this licensee has been one of the Region's
+ ' outstanding . security performer The problems discussed below became' apparent during the last half of the rating perio The ' security organizat'on, after the loss of- the security manager and the captain in charge of security personnel in late 1987,.was reorganized and incorporated into the Nuclear Protec-tion Service lwith a new manager, associate manager and several supervisory changes brought about by attrition. . Changes in management, supervision style and philosophy were not readily accepted by the security force. Management was also slow in recognizing situations which resulted in a deteriorating security morale and perfonnance. As a result, certain viola-tions were. identified in the latter part of the SALP period _and-an Enforcement Conference was held on January 6, 1989 to discuss the following items: failure to control access .to vital and protected areas; failure to control access to the area; failure to control access to a vital area (protected sleeping guard); failure to rotate locks and cores after terminating

measure; inadequate perimeter intrusion detection system; and
. inadequate-reporting of safeguards event Serious management attention to these weaknesses was provided after.this series of events which occurred in the last quarter of 198 These events and a resulting NRC inspection indicated that security performance in the area of personnel access control had reached a level of marginal performanc The repetitive access control violations indicate: a. breakdown in the supervisory oversight of the security force; a failure on the part -of the security force to recognize and correct problems; and a failure of management to implement effective corrective measures. The root cause analyses for the first access control problem was not effective in preventing recur- i rence. Management also demonstrated a lack of familiarity with !
basic security requirements as evidenced by the failure to e

' expertise or incorrect implementation of regulatory requirements, was' found by the NRC in the areas of intrusion detection equipmen Critical self-assessment was lacking, therefore problems were not identified at an early stag After initial identification of the above problems, the licensee responded by assigning a new General Manager Station Support and redefinition of responsibilities for licensee and contractor employees has been implemented.
I One violation was identified during this assessment perio .However, subsequent to the end of the assessment period, escalated enforcement action involving multiple examples of security deficiencies was issue Severity level IV violation for inadequate perimeter intrusion detection capability.

- Recommendations The Board has noted that during the first half of this SALP period the licensee enjoyed a favorable security program without .
the negative impact of enforcement issues. However, a serious degradation during the second half of this SALP period that could result, if unchecked, in a SALP 3 rating. In order to alleviate this situation the Board recommends that a high level of management attention continue to be given to this program are Engineering / Technical Support Analysis The Engineering Technical Support functional area addresses the adequacy of technical and engineering support for all plant activities. To determine the adequacy of support provided, specific attention was given to the identification and resolu-tion of technical issues, responsiveness to NRC initiatives, enforcement history, staffing, effectiveness of training, and qualificatio The scope of this assessment includes all
