- SYSTEMATIC ASSESSMENT OF LICENSEE PERFORMANCE REPORT SURRY NUCLEAR STATION 50-280/95-99 AND 50-281/95-99 BACKGROUND The SALP Board convened on February 2, 1995, to assess the nuclear safety performance of Surry Units 1 and 2 for the period July 4, 1993, through January 21, 199 The Board was conducted per Manag~ment Directive 8.6, "Systematic Assessment of Licensee Performance."
Board members were J. P. Stohr (Board Chairperson), Director, Division of Radiation Safety and Safeguards; E.W. Merschoff, Director, Division of Reactor Projects; A. F. Gibson, Director, Division of Reactor Safety; and D. 8. Matthews, Director, Project Directorate II-2, NRC Office of Nuclear Reactor Regulation. This assessment was reviewed and approved by the Regional Administrato I PLANT OPERATIONS This functional area addresses the control and executi-0n of activities directJy related to operating the plant. It includes activities such as plant startup, power operation, plant shutdown, and response to transient It also includes initial and requalification training programs for licensed operator Management oversight and involvement were effective during the SALP period, and were characterized by conservative decisions and safe operation While the plant was challenged by six trips during this period due largely to equipment failures, operators' response to these events was well controlled, focused on safety, prompt, and thoroug The Station Nuclear Safety Operating Committee consistently provided thoughtful review of issues at the appropriate threshol In addition, reviews associated with temporary leak seal repairs added value to these efforts, in that issues not recogn'ized by the line organization were identified and subsequently addresse Management fully supported operational personnel and established high performance standard Prudent testing was initiated for problems associated with th_e turbine driven auxiliary feedwater pum Management's onshift oversight during plant heatups and startups illustrated a strong commitment to plant safety. Shift operations were well controlled with conservative decisions made to control the tempo of operations during steam generator level oscillations. Early in the SALP period, an inadequate evaluation of a reactor coolant system leak resulted in Unit 1 operating with a non-isolable reactor coolant lea However, conservative actions taken on a subsequent increase in leakage rate resulted in the ultimate detection, analysis and repair of the leak prior to exceeding allowable leakage limit ENCLOSURE
Operations personnel performance was excellent throughout the assessment perio Plant evolutions such as shutdowns and startups, reactor trips, power operations and transients were conducted in a highly professional and competent manne Excellent command and control of the evolutions and the frequent use of feedback communications indicated that management expectations were fully understoo To assure successful evolutions, effective pre-job briefings were consistently conducte During shutdowns, occasional communication deficiencies contributed to personnel errors involving loop stop valve operation and control of the dilution flow pat Both the initial licensed operator and operator requalification training programs were satisfactorily implemente Six of seven personnel tested for initial licensing successfully passed th~ examinatio The training skills learned in the simulator were also evident during plant evolution Operators were knowledgeable of plant systems and used procedures successfull The operations organization was effectively supported by the statio Engineering and Maintenance support to emerging problems was prompt and effective in assuring operators' ability to manage problems with a conservative safety attitude. Self assessment has remained effective throughout the period due, in large part, to the extensive involvement in and ownership of the assessment program by the operations line managemen The Plant Operations Area is rated Category III. MAINTENANCE This functional area addresses activities associated with diagnostic, predictive, preventive and corrective maintenance of plant structures, systems, and component It also includes all surveillance testing, inservice inspection and other tests associated with equipment and system operabilit Management continued to maintain a strong commitment to upgrade the material condition of the plant. Significant progress was made in reducing leaks, improving coatings, and refurbishing damaged and corroded equipmen Several longstanding and recurring equipment problems were correcte Examples included replacement of pressurizer safety valves and component cooling water heat exchanger Effective engineering support and root cause analyses were important contributors to success in this are The procedure upgrade program, initiated in a previous SALP period, was continue Although procedural deficiencies continued to cause problems, the quality of procedures steadily improve Plant systems and components were appropriately tested to assure they would function properly in servic Effective programs were implemented for post maintenance, inservice, and surveillance testin Programs for diagnostically testing motor operated valves, predicting piping ENCLOSURE

degradation due to erosion and corrosion, and verifying the heat transfer capability of service water heat exchangers were also effectiv Teamwork contributed to good maintenance performanc NRC inspectors noted numerous examples of effective communications between operations and maintenance during pre-job briefings and during the accomplishment of maintenance activities. Engineering assisted Maintenance in the resolution of recurring equipment problem Human performance deficiencies in the implementation of maintenance and testing programs remained a challenge during this SALP perio Such deficiencies caused an automatic reactor trip, a manual reactor trip and power runback These deficiencies, and other personnel errors during maintenance and testing activities, were caused by lack of attention to detail and failure to follow procedure Equipment failures were also a challenge. Several reactor trips, forced outages and power reductions were caused by equipment failure Most occurred in the balance-of-plant equipment and some could have been prevented by more effective preventive maintenance of aging plant equipmen Self-assessments were a strengt The line organization candidly assessed performance trends using the performance annunciator panel program, and the QA organization provided daily performance reports to station managemen The plant staff maintained a low threshold for identifying problems as indicated by the large number of deficiency reports generated. Audits and assessments by the QA organization provided valuable performance feedback to station managemen Corrective actions taken in response to specific problems identified by self-assessments were generally timely and effectiv The Maintenance area was rated Category I ENGINEERING This functional area addresses activities associated with the design of plant modifications and engineering support for operations, maintenance, surveillance, and licensing activitie Management demonstrated a strong commitment to providing high quality engineering and technical support in maintaining safe plant operation In general, conservative and appropriate decisions were made by management with respect to operations, maintenance and surveillance activitie Engineering and technical support in resolving emerging issues in support of reliable plant operation was generally goo Trending and evaluation of the steam generator water level oscillations was comprehensive, timely, and provided valuable information to the operations staff. Engineering evaluation of a proposed modification to the 2A station battery was soun Operations, maintenance, and ENCLOSURE
engineering personnel coordinated efficiently to minimize the amount of time the station battery was out of service and to complete the temporary modification in a controlled manne A strong engineering training program was exemplified by the number of engineering personnel with Senior Reactor Operator or Shift Technical Advisor certificates. Management focused attention on engineering backlog control which yielded good results by reducing the number of backlog package Licensing submittals were timely and of high quality, demonstrating thorough understanding of the technical issues and regulatory requirement Responses to NRC Generic Letters adequately addressed issues of concer During the period, there were some problems which indicated a need to improve communications between engineering and station personne Examples were an error relating to the main steam calorimetric computer program setpoint, because the impact of the refined main steam scaling values was not recognized by all involved parties; and an incident relating to the gradual degradation of a station batter The self-assessment program was well organized, effective, and performed by knowledgeable people. Assessments were effective in identifying a number of areas for improvement in the engineering grou Corrective actions in response to the audits and assessments were developed to address the improvement area The review of the Technical Specifications and implementing procedures was thorough and significantly improved the quality of the surveillance progra The Engineering area was rated Category PLANT SUPPORT This functional area addresses all activities related to the plant support function including radiological controls, radioactive effluents, chemistry, emergency preparedness, security, fire protection and housekeeping control The radiological control program continued to provide an excellent level of protection for plant workers and the environment during this SALP perio Proactive As Low As Reasonably Achievable (ALARA) efforts resulted in collective dose savings and supported the continued downward trend in collective dose for the sit ALARA initiatives included the effective use of permanent shielding on operating systems, hot spot reduction and refinements to shutdown chemistr There was strong management and worker involvement in support of the progra Radiological contamination control practices continued to be aggressive and supported the effective control of internal exposures during the perio Self audits of the radiological protection, chemistry, radioactive waste, and transportation programs were comprehensive and well documente Corrective actions for audit findings were *
