~ 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. The SALP is supplemental to normal regulatory processes used to ensure compliance with NRC rules and regulations. The 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 the quality and safety of plant construction and operatio An NRC SALP Board,tomposed of the staff members listed below, met on May 16, 1988, to review the collection of performance observations and data to assess the 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 for the J. M. Farley facility for the period August 1,1986 through March 31, 198 SALP Board for the J. M. Farley facility:

A. F. Gibson, Director, Division of Reactor Safety, RII (Chairman)

C. W. Hehl, Deputy Director, Division of Reactor Projects (ORP), RII D. M. Collins, Acting Director, Division of Radiation Safety and Safeguards, RII D. M. Verrelli, Chief, Projects Branch 2, DRP, RII E. G. Adensam Director, Project Directorate II-1, NRR W. H. Bradford, Senior Resident. Inspector, Farley, ORP, RII E. A. Reeves, Senior Project Manager, Project Directorate II-1, NRR L Attendees at SALP Board Meeting:

t L K. D. Landis, Chief, Technical Support Staff (TSS), DRP, RII H. C. Dance, Chief, Project Section 2B, ORP, RII L. P. Modenos, Project Engineer, Project Section 28, DRP, RII W. Miller, Resident Inspector, Farley, DRP, RII II. CRITERIA Licensee performance is assessed in certain functional areas depending upon whether the facility has been in the construction, preoperational, or operating phase. Each functional area normally represents an area which is significant to nuclear safety and the environment and which is a normal programmatic are 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 f I' t 4 -

'

\.

One'or more of the following evaluation criteria were used to assess each functional area; however, the SALP Board is not limited to these criteria

'and others'may have been used where appropriat Management. involvement in assuring quality Approach to the resolution of technical issues from . a safety standpoint Responsiveness to NRC initiatives

' Enforcementhispory Operational and' construction events (including response to, analysis of, and corrective actions for) Staffing (including management) Training and qualification effectiveness

! Based upon' the SALP Board assessment, each functional area evaluated is classified into one of the three performance categorie The definitions of these performance categories are:

Category 1: Reduced NRC attention ma, be appropriate. Licensee management attention and involvement ara 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 or construction is being achieve C.a tegog(;2: NRC attention should be maintained at . normal lavel Licensee management. attention and involvement are evident and are concerned with nuclear safety; licensee resources are adequate and i are reasonably effective so that satisfactory performance with respect to operational safety or construction is being achieve Category 3: Both NRC and licensee attention should be increase Licensee management attention and involvement is acceptable and considers nuclear safety, but weaknesses are eviden Licensee resources appear to be strained or not effectively used so that minimally satisfactory performance with respect to operational safety or construction is being achieve The functional area being evaluated may have some attributes that would place the evaluation in Category 1, and others that would place it in either Category 2 or The final rating for each functional area is a composite of the attributes tempered with the judgement of NRC management as to the significance of individual item , , - .a-

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 level. 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 perio III. SUMMARY OF RESULTS 4 Overall Facility Performance The Farley facility is well managed by qualified and experienced personnel. Senior plant managers hold active senior reactor operator licenses and the site is supported by a corporate organization that is composed of personnel who have extensive backgrounds in nuclear plant management and operations. The licensee remains responsive to NRC concerns and the organization is safety oriented. Strengths were identified in the areas of plant operations, radiological controls, fire protection, outages, and licensing activitie The Farley Nuclear Plant was effectively managed and continues to achieve a satisfactory level of operational safety. The licensee has strong programs in all aspects of plant operation. The licensee has set high standards for cleanliness, radioactive waste control, and general plant operations. The licensee is dedicated to long run time and short refueling outage Farley has established an excellent long-term operating record. The work force is stable which is conducive to good relations between management and personnel and a high experience level in the operating staf Plant operations personnel respond to plant trips in a professional and competent manne There is strong plant support from a very capable corporate staff. However, there were certain areas of concern which were noted and require management attentio These areas include quality programs and engineering suppor Throughout the SALP period, a common problem of failure to follow procedures was noted. Continued management attention is required to assure improved performance in procedural complianc The licensee has initiated corrective action from a Self Assessment Program that identified problem areas and established specific goals for improvemen ^

6 management control and interface was noted at status meeting Operations management conducted routine plant and control room tours and had initiated employee interface meetings to improve communications and expedite problem resolution. Operators had a positive attitude towards operations and plant managemen Overall control of plant operations was well planned with established and realistic prioritie The licensee was responsive to problems identified by NRC. The licensee generally demonstrated knowledge of regulations, ,

guides, standards and generic issues; and interpretations of these documents and associated issues were usuclly conservativ An exceptian to this was the classification, without supporing analysis, of safety related room coolers as attendant equipment instead of required equipment for operability determination Licensee technical competence was well founded both in technical matters and general plant operations. The plant staff responded to plant trips and other operational events during this review period in a professional and competect manner. Daily conduct of business in the control room was performed in a professional manne The plant staff is normally observant of Limiting Conditions for Operation (LCOs) and was generally conservative in its application of action statement requirements. Profes-sionalism is very evident throughout the site organizatio Control room operations appear to be well organized. The operating shif ts are uniforme The staff organization, comunications between the various operations personnel and shift turnover was good; hor ver, during the Operational Performance Assessment (OPA),

shift turnovers were observed. omeThepoor communications fire during protection adminis-trative workload was heavy and distracted from other Shift Supervisor duties. Shift crews were composed of degreed and non-degreed individuals resulting in a balance of engineering expertise and plant experience. The Operations staff has had a low turnover rate which has resulted in a high experience level in the operating staf Control room drawings were easily accessible, accurate, very legible, and in very good physical condition with a mylar protective coating. Shift logs were well maintained. The failure to maintain procedure and drawing controls in other areas of the plant had been identified by the licensee's Safety Audit and Engineering Review (SAER) internal audit on two occasions. Although the problem was reportedly corrected, a subsequent SAER audit identified that the corrective action was inadequat Additional examples of incorrect procedure and drawing revisions were identified by a subsequent NRC inspection and a violation for inadequate corrective action was issue i

Access to the control room was controlled and limited to !

personnel conducting busines Radios and reading material not directly related to plant operation are not allowed in the control room or plant.- The control boards had few outstanding maintenance work requests / deficiency tags. The licensee appears to place proper emphasis on maintenance of control board instru-mentation. The control room operators were cognizant of lit annunicators on the main control board and the number of lit annunciators were kept to a minimum. Color coding of instru-mentation in the control room and plant doors reflected human factors consideration. The majority of piping was also labele The licensee is in the process of upgrading an equipment labeling progra There was good member participation during Plant Operations Review Committee (PORC) meetings and evidence of strong manage-ment contro These aspects were considered to be a strength of the PORC review proces The PORC appeared to be accomplishing their mission and performing adequate reviews and safety evaluation NRC evaluations of programs for control of equipment indicated that certain weaknesses existed. Guidance on post-maintenance testing was limited and heavy reliance was placed on the Shift Supervisor and operator experience to determine the scope of testing needed. Several problems in the tagging of equipment were noted. Examples of problems identified and supported by incident reports are: hold tags lacked sufficient information to allow prompt reference to a specific clearance or to equip-ment tagged; inadequate MWR details making tagging more diffi-cult; use of standard tagouts is limited; and some Shift Foremen Inspecting were nct adequately trained or experienced in reading electrical schematic drawings. Licensee trending and evaluation of these incidents and other plant events had been initiated only toward the erd of the assessment period. Some safety-related charging pJmp valves were found locked at the valve rather than at the remote operator. These valves could be inaccessible under accident condition Four reactor trips occurred on Unit 1 during the assessment period. Two trips were caused by equipment malfunction and two trips were cause by operator erro Unit 2 had three reactor trips during this perio Two trips were caused by equipment malfunction and one trip was caused by operator error. Above 15% power, the Farley reactor trip rate of 0.26 per 1000 critical hours compare favorably to a national average of 0.4 Reactor Trip sumaries are provided in Section Four violations were identifie All the violations involve procedural adherence problems.

. Analysis During the assessment period, inspections were performed by the resident and regional inspection staff The inspections included four routine radiation protection inspections, four routine radiological effluents and chemistry inspections which included confirmatory measurements using the Region II mobile laboratory, and two reactive inspections as a result of the transfer of licensed radioactive material to an unauthorized recipient and an unauthorized entry by a licensee employee into a high radiation area greater than 1000 mrem / hou The licensee's health physics and chemistry staffing levels were appropriate and compared well to other utilities having a facility of similar size.

chemistry technicians were available to support routine and outage operations. Key positions in the radwaste management program and environmental surveillance programs were also filled with qualified staf ,

The knowledge and experience level of the site health physics and chemistry staffs were good. The staff had a low turnover rate and _ an ef fective training program which has received INP0 accreditation. The performance of the staff in support of routine operations and outages was goo Management support and involvement in matters related to radi a ti on protec tion , radwaste control and chemistry were very good as evidenced by procurement of new laboratory counting equipment and addition of a new radwaste solidification facility. Health physics management was involved sufficiently early in outage preparations to permit adequate planning. The plant's radiation protection manager and plant chemist received the support of other plant managers in implementing the radiation protection and chemistry programs, Resolution of technical issues by the health physics and chemistry staff was good as evidenced by the development of a-Hot Particle Control Program which included the use of contami-nation containments, ventilation systems and special training of HP technicians in the detection, identification and retention of hot particles on equipment and personnel. Satisfactory resolu-tion of technical issues vis further evidenced by the develop-ment of radiological controls for retrieval of a safety injection line thermal sleeve which was retrieved from Unit 2 reactor vessel. Radiation controls within containment were observed by the NRC during Unit 2 refueling outage when the loose 6-inch safety injection nozzie was recovered from the reactor vessel . The evolution was well organized and dose results were maintained below the planning value Responses to NRC initiatives were. conducted in an effective and acceptable manner as evidenced by the development of improved training elements for sampling radioicdine during accident conditions and the revision of procedures to describe trainin The licensee received a Severity Level III violation for failure to adequately control access to a high radiation area greater than 1000 mrem / hour with a locked door to prevent unauthorized entr An individual inadvertently entered the high radiation area thereby causing a potential for a significant overexposur The licensee elected to control access to a high radiation area in the auxiliary building with dose rates up to 240 R/hr with a L

. personnel on exclusion area controls, expanding all exclusion area boundaries to control access by a locked door, adopting a new systeca for issuance of exclusion area keys, and modifying the Radiation Worker Training Course to include the controls and precautions for exclusion area The licensee's radiation. work permit and respiratory protectior, programs were found to be satisfactory. In December 1986, the amount of contaminated area was 21,130 square feet which represents 18.1% of the radiologically controlled area of the plant. In 1987, the licensee reduced the total contaminated area _ to 12,986 square feet, which represented a 39% decrease from 1986. In 1987 there was a 5.7% decrease in the number of clothing and skin contamination incidents compared to 198 The 1987 cumulative radiation exposure was 299 person-rem per uni This compares better than the national average exposure of 368 person-rem per pWR unit. This lower than average collective dose resulted from the aggressive exposure control program established and implemented by 'the licensee. The licensees' action to raise the pH of the Reactor Coolant System (RCS) to reduce plateout of Co-60 demonstrates initiative toward reducing exposure. This reduced plate out resulted in a 50%

u red'ction in the radiation levels in the Steam Generators (S/Gs)

during shutdown maintenance activities. The use of a com-puterized exclusion area access authorization system for S/G work (stay times calculations and positive control over entries)

also resulted in the lowering of' radiation dose During 1987, the licensee disposed of 9,411 cubic feet of solid radioactive waste per unit containing 334 curie This is approximately 50% of the total waste shipped by the licensee in 1986. This low amount is due primarily to a dedicated solid waste reduction program and the addition of a new radwaste solidification system which should further reduce the amount of radioactive waste generated. During the assessment period, the licensee received a Severity Level IV violation for shipping contaminated mechanical snubbers to a recipient unauthorized to receive any radioactive material. The licensee took prompt and effective correction action to ensure that all material which had been inside the RCA was surveyed by licensee health physics personnel prior to offsite shipment by warehouse personne _ - _ _- __ _ - ____ _ __ _ _ _ _ .

A confirmatory ' measurements inspection indicated that the licensee's counting results met the established NRC criterion for comparing counting results except that a . negative bias was observed for a 14cc vial gas sample from the waste gas decay tank. This bias was attributed to sample preparation techniques because the bias was consistent for the four detectors for all isotopes. During an inspection in March 1988, the licensee received a violation for failure to make attenuation corrections for self absorption of gamma photons in a solid polymer standard which was used for calibrating the detectors for counting gaseous sample Count room equipment was, in general, not state-of-the-art since it was procured in the early 1970 However, the licensee has orderad new equipment and expects onsite delivery by the latter half of 198 A simulated liquid waste sample which contained H-3, Sr-89, Sr-90 and Fe-55.was provided to Alabama Power Company in May 1987 by the NRC. The licensee's results compared favorably with the NRC established criterion for comparing analytical re:ult Liquid and gaseous radioactive effluents were within the Technical Specification limits and in compliance with 40 CFR 190 limits for radiation dose and radioactivity concentration in effluents. Fission and activation products in the gaseous effluents for 1987 were 35% lower than in 1986. Also, 1987 values for gaseous iodines and particulates were 75% lower than 1986 values. In general, gaseous effluents for Farley Unit I have been steadily declining since 1982 when Farley experienced problems with failed fue Radioactivity in the liquid effluents was 47% lower in 1987 as compared to 1986. Tritium in liquid effluents has remained essentially constant for the past three years. Gross alpha radioactivity in the liquid effluent curies (C1) per year. Annual was essentially effluent releasebackground, 2E-5,1985-1987can be found in summaries for Section The licensee reported a total of five non-routine releases (three liquid releases and two gaseous releases) during 198 The gaseous releases occurred on Unit 2 and totalled 8.7 E-6 C These monitored, planned releases were caused by steam generator pressure pulse cleaning and steam generator helium leak testin The non-routine liquid releases occurred on Unit 1, and a total of 8.65 E-5 Ci were released. Two of the releases were due to a Refueling Water Storage Tank barrier penetration leak, and a third release was caused by a leak in the pumping equipment on the Reactor Makeup Water Storage Tank.

-12 Radiation doses to the maximally exposed offsite individual from liquid and gaseous effluents for 1987 were calculated to be 0.16 mrem to the whole body and 0.17 mrem to the critical orga These values were consistent with previous annual dose estimates and below 40 CFR 190 limit The licensee continued to meet the criteria for good chemistry control established by the Steam Generator Owners Group and Westinghous However, general corrosion of carbon steel pipe throughout the secondary coolant system continued to result in hundreds of pounds of "sludge" being transported to the steam generator Since this sludge had already initiated tube denting, .the licensee continued to add boric acid as well as AVT control chemicals (ammonia and hydrazine) to the feedwate This action, in turn, complicated the pH control needed to prevent general corrosion and pipe thinning. Consequently, the licensee planned to take two major steps to provide additional protection to the steam generators. During refueling outages (October 1987 and April 1988) the steam generators were cleaned by a pressure pulse technique in an effort to remove solid iron-copper oxides from tube-tube sheet crevices and from the secondary sides of the steam generator tubes. Secondly, beginning in the next fuel cycles, morpholine will be substi-tuted for ammonia for pH control in an effort to maintain higher pH conditions in the carbon steel pipin Six violations were identified as follows: Severity Level III violation with three examples:

(1) failure to adequately control access to a high radiation area, (2) failure to follow procedures, and (3) failure to adequately instruct individuals working in or frequenting a restricted, area (348, 364/88-02), Severity Level IV violation for failure to assure that a recipient was authorized to receive radioactive material (348,364/86-26). Severity Level IV violation for failure to comply with 00T regulations applicable to the transportation of radioactive material (348, 364/86-26). Severi ty Level IV violation for failure to follow the requirements of a radiation work permit (348, 364/87-28). Severity Level IV violation for failure to maintain records of survey when local instrumentation was out of service (364/87-29).

13 Severity Level V violation for failure to make, attenuation corrections for self absorption of gamma photons in a solid polymer . standard used for calibrating the detectors for counting gaseous samples (348,364/88-10). Conclusion Category: 1 Recommendations A high level of performance was achieved in this area. The NRC staff reso6rces applied to the routine inspection program should be reduced!

C. Maintenance Analysis During the assessment period, inspections were conducted by the resident and regional inspection staff Management involvement in maintenance planning and practices were evident. The daily planning meetings were observed to be used effectively in communicating station maintenance activities and in prioritizing work. The inclusion of Senior Reactor Operator (SRO) qualified individuals on the planning staff was observed to be an asset in maintenance plannin The licensee recently ertablished an aggressive program that has reduced the number of active Maintenance Work Requests (MWRs).

The effort to reduce the number of backlogged MWRs, and the practice of keeping plant personnel aware in this area is a strength in maintenance are Licensee maaagement initiated and completed a Self-Assessment Program which delineated eight specific problem areas. They established goals to upgrade and improve the maintenance practice This includes items such as: developing a mainte-nance procedure writers guide; developing additional needed

, maintenance procedures; revising existing maintenance procedures l

to incorporate vendor manual guidelines; integrating corrective L

'

maintenance with required planned maintenance; developing performance teams to improve communications, and, developing methods to assure complete work request packages. The self-assessment findings by the licensee reflected many of the same concerns identified by the NRC. The licensee's report appeared to be an objective characterization of problems the licensee is

either' facing or can expect to face as the plant ages. The straight-forward approach to these problems and realistic solutions proposed, are evidence of recognition. of problems in

. maintenance and. sound forethought in the area of plant manage-ment. The Self-Assessment Program was considered a. strength to the maintenance support of operation Use of the Nuclear Plant Reliability Data System nas increased the licensee's awareness of potential plant problems. Upgrades in the Farley Nuclear Plant Information Maintenance System and implementation of data verification has improved the data base used for maintenance planning and scheduling. Staffing increases 4added maintenance planners who provided better scheduling and coordination of the activities of each mainte-nance disciplin The licensee utilizes a predictive maintenance analysis which includes oil and vibration analysis on mechanical equipment and infrared analysis on electrical equipment. These techniques have enabled the licensee to predict degrading trends in equipment performance and e f fer.t repairs before equipment failure occur Plant equipment condition and housekeeping was well maintained; however, in one case scaf folding was attached to safety-related equipment without being analyzed for seismic consideration Concerns with the lack of written maintenance procedure for work on safety-related components, lack of valve torquing i specifications, inadequate root cause evaluations on ASCO l solenoid valves and the lack of independent verification requirements for jumpers placed by KWRs were identified as weaknesses in the licensee's control of work activities. It is noted that, in some KdRs, jumpers had been used for various troubleshooting activitie Technicians were required to document use of temporary alterations such as lifted leads, jumpers, and sliding links on a continuation sheet of the MW However, independent verification for jumpers was not a require-ment in the administrative control procedure. Documentation of root causes for component failures were not always clear or in some cases were missing completely. For example, KdR failure descriptions, such as "blown fuse", had no documented determina-tions of root causes, and adequate root cause evaluations were not performed for some ASCO solenoid valve failure The licensee's program also failed to flag overdue lubrication Also, an acceptable grace period for overdue lubrications had not been specifie l l

As of November 1987, there were in excess of 400 backlogged Preventative Maintenance (PM) work authorizations. It was noted that there were problems completing the PM tasks because of the volume of corrective maintenance being performed and due to the difficulty in coordinating PMs between the disciplines on the same. system PM coordination problems were recognized in _the licensee's maintenance self-evaluation, and plans exist to implement a computer-based repetitive task program to administer the PM progra The licensee had been attempting to terminate fouling and corrosion of service water pipes by macro- and micro-organisms through th6 development of improved biocide treatment to replace the chlorination program currently used. However, prior to 1986, the licensee's efforts to control the . infiltration of clams into the service water system had not been given adequate

Surveillance Analysis During the assessment period, inspections were performed by the resident and regicnal inspection staff These included activities related to inservice inspection and testing, surveillance, and containment integrated leak rate testin Routine plant surveillance-related activities were planned and well defined. The lack of administrative controls over the use of "not applicable (N/A)", in surveillance and operating procedures, was noted as a weakness in management control of surveillance testing. Inappropriate use of "N/A" inserted for a surveillance prerequisite step was a contributing factor in the RHR "A" tra'n event, where 2200 gallons of water was discharged through the Pressurizer Relief Tank rupture disc to the containment sum Reviews of surveillance activities were performed by prescribed licensee reviewers who were qualified to perform these activitie Review of surveillance records

The licensee's surveillance procedures were technically adequate, executed satisfactorily and test results were acceptabl Integrated leak rate testing for Unit 2 was witnessed by the NRC staff during this performance period. The test procedure showed evidence of prior planning, assignment of responsibility and control of test activitie The licensee utilized highly qualified contractor test personnel to assist in testing and data evaluation. Problems identified were quickly elevated to higher management. The test procedure was followed and any changes were properly documented. Test personnel and management demonstrated a general understanding of leak rate issue Resolutions of issues were reasonably conservative, sound and timely. Staffing and training were adequat An inspection was performed in the areas of emergency diesel generator (EDG) surveillance tes, ting, emergency start logs, and annual reliability reporting. In the area of EDG surveillance

The licensee's procedures for-the administrative control of fire hazards within the plant, surveillance and maintenance of the fire protection systems and equipment, and organization and training of the plant fire brigade were found to meet the minimum NRC requirements and guidelines.-

The staff's inspection also reviewed the licensee's implementa-tion of' the fire prevention administrative control General housekeeping and control of combustible and flammable materials in safety-related areas were found to be very good. The fire protection extinguishing systems, fire detection systems and fire rated assemblies protecting plant systems required for safe shutdown gere found to be functional, or appropriate' compen-satory measures were employe In addition, the surveillance inspections, tests'and maintenance of the plant fire protection systems were found to be satisfactory and current' as required by the plant technical specification The organization and staffing of the plant fire brigade meet the requirements of plant technical specifications and NRC guidelines. Fire protection staff positions were identified and authorities and responsibilities were clearly define personnel were well qualified for their assigned dutie The training and drill records for the individual fire brigade -

members reviewed were found to be current and satisfied the requirements of plant procedures and NRC guidelines. However, it was identified that the number of shift fire brigade drills conducted during three quarters of 1986 did not satisfy plant procedural requirements of six drills per quarte /,See violation b)

The annual and triennial fire prevention / protection QA audits were conducted within the specified frequency and appeared to cover all of the essential elements of the fire protection program. The licensee had implemented corrective actions or was reviewing the items to determine the appropriate corrective action .

With the exception of the violations identified, the management

involvement and control in assuring quality in the fire protec-tion program is evident due to the involvement in the site fire protection program, and the implementation of fire protection procedures which meet NRC guideline The licensee's approach to the resolution of technical fire protection issues indicates an apparent understanding of issues.

F. Emergency Preparedness Analysis

.

During the assessment period, inspections were performed by resident. and regional inspection staff These included observation of the annual emergency preparedness exercises in December 1986 and September 1987. A routine emergency preparedness inspection was performed in February 1988. Two Radiological Emergency Plan (REP) revisions and three temporary change notices were reviewed during the assessment perio ,

Observation and critique of the exercises indicated that the REP and Implementing Procedures could be adequately implemented by the licensee, although several weaknesses and areas for improvement were identified by the licensee and NR These items were formally documente The licensee committed to corrective actions consistent with regulatory criteria and guidance. One weakness identified involved failure of the offsite monitoring teams to implement field monitoring require-ments as listed below. This weakness was indicative of inadequate training of the offsite monitoring team The teams did not; Define and report to the TSC and/or EOF the specific locations at which radiological monitoring data were obtaine _ _ _ _ _ _ _ _

An additional weakness was identified in which the licensee failed to include in the initial protective action recommenda-tion, the 22.5 sectors immediately adjacent to the principal zone exposed to the plum Areas requiring improvement were the completion of initial notification of emergency declarations and subsequent followups of same, and use of appropriate notification forms for Site Area Emergency and General Emergency declarations. Elements of emergency response determined to be acceptable were: emergency detection and classification; protective action decisionmaking, except as discussed above; shift staffing and augmentation; public information; annual quality assurance audits of plant and corporate emergency preparedness programs; changes to the emergency plan and implementing procedures; coordination of offsite agencies; and identification of deficiencies and required improvements during drills and exercises.

'

The routine emergency. preparedness inspection resulted in a violation for the licensee's failure tv provide annual communi-cations training to an Operation Shift Aide designated to j perform such functions.

l l During this assessment period, Region II forwarded to the licensee the FEMA finding that the alert and notification system installed around the Farley Nuclear Station did not satisfy the requirements of NUREG-0654/ FEMA-REP-1 and FEMA-43. At the close of the assessment period, the licensee was g anted an extension

'

for completion of required actions involving the subject system 1 and the date the system will be re-evaluated. The licensee had requested from FEMA, additional information on the findings, in orde to better define needed corrective action One violation was identified.

resident and regional inspection staff The Regulatory Effectiveness Review (RER) report for the RER which had been conducted during the previous rating period was issued. - The ,

report identified a potential safeguards vulnerabilit The licensee has taken interim corrective measures to protect-against the potential safeguards vulnerability discovered by the RER inspectio Additionally, the licensee has completed engineering studies and selected replacement equipment to upgrade security hardware and physical security aids which were found deficient during the inspection. The licensee management had increased their awareness of and involvement in the security program, and have worked closely with the Office of Nuclear Reactor Regulation to establish a technically sound physical security upgrade program. An extensive construction project for installations of the upgraded physical security system was

Outages Analysis During the assessment period, inspections were performed by the resident, regional, and headquarters inspection staffs. Two refueling outages were performed on Unit 1 in October 1986 and March 198 One maintenance outage was performed in January 1988 for environmental qualification work on electrical components. Unit 2 had one refueling outage in October 1987 and one maintenance outage in December 1987. This latter forced outage- was due to a through wall crack on a six-inch safety injettion line. Major activities conducted during the refueling outages consisted of: Unit 2 steam generators pressure pulse cleaning; replacement of new anti-vibration bars in all steam generators on Units 1 and 2; local leak rate testing and containment integrated leak rate testing; replacement of service water 2 inch and under carbon steel piping with stainless steel; extensive environmental qualifibation upgrade of equipment; installed forced cooling for 7300 process cabinets and shutdown panels; changed cooling water supply on charging / safety injec-tion pumps from service water to component cooling water; installed ATWS Mitigating Scram Actuation Circuity; replacement ef Anchor / Darling tilting disc check valves with lift check valves in the emergency auxiliary feedwater system; reactor vessel head conoseal modification; motor operated. valve evalua-tion and testing program (MOVAT); modified MSIV test cylinders; and, repair of upper and lower internals lif ting rig tool for Unit 1 damaged during the ten year ISI core barrel lif The licensee followed management approved refueling procedure The procedures were enhanced by monitoring up-to-date fuel status boards inside and outside containment.

licensee scheduled and followed the refueling outage with the aid of flow and critical path charts. At the conclusion of each refueling outage, the licensee conducted a review of all completed wor Problem areas were identified and. analyze Special attention was given to these areas for future refueling outage schedulin The licensee's overall control and planning for refueling-outages results in a well planned and controlled evolution. All work is planned with regard to scope, repair parts and work procedures. Planning for the next refueling outage starts at the conclusion of the present outage. There are in the order of 70 to 100; modifications performed on each unit during refueling outage with each refueling outage typically scheduled '

for six weeks. Extensive operator training is conducted prior to the subsequent plant startup to familiarize personnel with plant modification The licensee's interface and control of contractors during refueling outages has become stronger. This is primarily due to business meetings which the licensee has set up with the contractors prior to the start of the wor Licensee management involvement in inservice inspection (ISI)

activities and decision making was at a level that assured adequate management revie Records were complete, well maintained, and available. Strict adherence to procedures and policies was maintained. However, during the OPA, review of ISI problem reports indicated that responses were not being sent back to the System Performance Group nor was that group pursuing the closeout of the problem reports. As a result, non sa fety-related Code C coupling bolts were left installed in the 1A and IB charging pumps af ter the replacement bolts were sent to the site. For this problem, the licensee failed to perform an evaluation of equipment operability after discovery of the nonconforming material . This item was dispositioned as an

The licensee has initiated use of containment maintenance coordinator Their function is to control and expedite the work in the containment building during refueling outages. The coordinators also ensure the polar crane is used in accordance with the refueling schedule. This appears to have increased coordination and productivit No violations or deviations were identified l

Quality Programs and Administrative Controls Affecting Quality Analysis 4 During the' assessment period, inspections were performed by the resident and regional inspection staff For the purposes'of this assessment, this area is defined as the ability of the licensee to identify and correct their own problem It encompasses all plant activities, all plant personnel, as well as those corporate functions and personnel that provide services to the plant. The plant and corporate QA  :

staff have responsibility for verifying quality. The rating in this area specifically denotes results of the various groups in achieving quality as well as the QA staff in verifying that qualit The OPA conducted in February and March 1988 identified that the Safety Audit Engineer Review (SAER) group conducted performance based and effective audits. SAER is staffed by rotating experienced plant personnel into the SAER group for three to five year This adds plant experience to the SAER and QA experience to various plant positions. The SAER audits both safety-related and nonsafety-related area SAER audits identify significant technical finding ;

o The OPA noted problems with the QC "peer" review system. This was identified by the SAER, but since the deficiencies continue to occur, corrective actions were inadequat The OPA found that supervisors (acting in the QC capacity) did I not perform independent observations of procedure quality control check points in 1985, 1987, and none through March 9, 1988. QC did observe three maintenance tasks in 1986. This *

periodicity of performing periodic assessments is considered to i be a weakness in assuring that quality control checks are being '

adequately accomplishe t

A self-assessment conducted by the licensee late in the SALP period demonstrated the ability of management to identify performance problems and to plan ' steps for improvement. Several problems identified by the OPA inspection had been previously identified by this self-assessment and corrective actions were underway. .This is a positive indication of management's recent '

performance in recognizing and providing solutions to problem However, the licensee was not effective in identifying and subsequently correcting problems in the area of EQ and procure-ment control. The licensee was not aware of long-standing problems in this area until they were identified by NRC and

. followup , licensee inspections during this SALP period. The licensee has been slow to acknowledge and correct some of these problem Escalated enforcement is under consideration. EQ problems are discussed in more details in Section IV.L of this repor The NRC also conducted a special inspection in the area of vendor interface including procurement control. Repetitive deficiencies in the use of commercial grade components in safety-related applications were identified. Similar problems had been identified during a previous NRC inspection. These

~

findings indicate the licensee was not effectively correcting identified problems. Escalated enforcement is under consider-ation. These findings are discussed in more detail in Section IV.C of this repor Hydrogen gas accumulation wat reported by the license in the low head safety injection line (charging pump suction line) during March 198 Historically, since 1979 the licensee experienced gas binding problems in the charging pumps on Unit 2 during testing and startup. In 1981 a proposal was made to install a

-

vent from the 2B pump suction to the Volume Control Tank to correct the gas accumulation problem. In March 1982, the NSSS vendor recommended installing vents on both Unit 1 and 2 safety injection line. In January 1988,.the proposal to install a vent on the 2B charging pump suction line was cancelle The licensee had been aware of this problem since 1979 but had not instituted permanent corrective action other than running or venting the pump. The licensee was not aggressive in correcting this problem. Escalated enforcement action is unoer consider-ation.

Licensing Activities' Analysis During the assessment period, the licensee has once again continued ato show a competent and dedicated managemen Management.is alert to issues involving plant safety and public health and safety. The. management -takes an active part in resolution of any problem in the normal licensing reviews. _The licensee's submittals to the NRC are well thought out and follow-up is actively pursue The licensee's submittals are usually timely and very well prepared. Tt e licensee submitted only three requests for changes to the Technical Specifications in support of the Unit 2 refueling outage, which ended in early December 1987. For these submittals, the staff had some difficulty in completing review of the two actions relating to steam generator tube sleeving and increasing the tube plugging limit. For example, the licensee's

submittal for the sleeving required three supplemental sub-mittals and numerous teleconferences to resolve NRC staff concerns. The submittal for an increase in the tube plugging limit also required three supplemental submittals prior to NRC acceptance. These issues were very technical in nature, among the first of a kind, and involved significant interface with the NSSS vendo ,

Most applications submitted by the licensee during tt '; SALP period were clearly well written with the safety analysis fully supporting the requested actions. Overall, we consider that the licensee continues to demonstrate a clear understanding and approach to resolving technical issues relating to licensing activitie The licensee's management demonstrates active participation in licensing activities and keeps abreast of current and antici-

pated licensing actions. Management control and oversight of licensing activities is generally satisfactor The licensee has adopted a computerized tracking and scheduling system that provides management an excellent tool for scheduling and prioritization of licensing activities initiated by their staff or by the NRC staf Thi tool was used extensively in

The briefing understandg)asngaofdemonstration by licensee the technical issues . management involve of a clear Following the meeting, the -licensee provided a -written summary documenting their plan to resolve the issue. Subsequently, Region II issued a {onfirmatory Action Letter prior to startup of Unit 2 on December 2, 1987. A subsequent team inspection of the entire equipment qualification area revealed weaknesses described in Section IV.I and IV.L. of this repor The licensee consistently demonstrates a clear understanding and approach to evaluations to justify the no significant hazards consideration determination provided in accordance with 10 CFR 50.91. These evaluations are thorough and clearly sound and, i most: cases, are used by direct quote in the Federal Register without chang This is a definite plus for the licensee's licensing managemen The licensee keeps abreast of industry approaches to the resolution of general plant safety issues and demonstrates an awareness of programs a't other facilitie This has been accomplished through membership in most major utility advisory and owners' groups. Licensee management has been represented in leadership positions in many of these groups. The licensee has resolved most of the multi plant safety issues. One example of excellent lic3nsee responsiveness.to NRC initiatives resulted in issuance of Technical Specification surveillance requirements for the Containment Ventilation System during this SALP perio The issue is a complex one where the NRC staff needed added assurance of leak tightness integrity and operability of certain containment vent valves.

Category: 2 Recommendations None Training and Qualification Effectiveness Analysis During the assessment period, inspections were conducted by the -

resident and regional staff Inspections included two licensing examination site visits and one requalifications program evaluation. Assessment of training effectiveness were also made during the OPA noted previousl The resident inspectors have had numerous occasions to inspect the training received by licensed and non-licensed personne The inspectors have observed simulator training and have reviewed the licensed operator requalification training material. The inspectors have observed and reviewed certain hands-on training at the training center and have reviewed instruction' material for non-licensed personnel. The training center is state-of-the-art. The instructors are considtred to be very proficient and well qualified in their positions. The training programs which are prescribed for each craft are a required and continuing training evolution. Each program is an indepth coverage of all required work evolutions. Each training phase requirrj craftsmen to successfully complete an examination on that portion of the training. .The observed training has been professional, comprehensive and well received by personne Additionally, the ten program areas of training for plant personnel have been accredited by INP The majority of the operators interviewed during the OPA indicated that both initial and requalification training were adequate and had improved substantially over the last two year Interviews also indicated that the practice of operating crews attending requalification and simulator training as a crew enhanced the interface and teamwork within the crew, Simulator training was highly praised and operators indicated that plant

Although the interviews indicated that these errors did not significantly detract from the effectiveness of training, a feedback program did not include a method to notify the ' initiator that 'the material was revised; thus, closing the loop and encouraging additional operator response The licensee rotate > Senior Reactor Operators (SR0s) through the "

Training Department. This practice enables a high experience level to be maintained among the instructional staf A trainirik weakness in tagouts and independent verification appeared to contribute to repetitive operational error Concerns were identified with licensee's EQ training progra At the time of the inspection, licensee's supervisory and management staff had not been trained in the requirements of the EQ progra Management training was identified as an area of strength. Most members of plant management hold current SR0 licensee In March 1987, retake examinations were given to four operator i candidates who had failed previous examinations. All four

NRC inspections found that the licensee's program for EQ was marginal during the early development stages of the EQ progra Management developed a "mind-set" that they had implemented an adequate EQ program in spite of emerging NRC Notices and Generic Letters. This led to the lack of adequate and prudent actions being taken by APC0 management in implementing an effective EQ program,-including inadequate staffing, unqualified installed EQ equipment, . failure to perform adequate walkdowns of EQ equipment, inadequate training on EQ, and a lack of under-standing of EQ issues in general. The licensee's in-house capability on EQ was weak with extensive dependence placed on contractor The. licensee did not choose to join outside'

industry groups on EQ and did not keep pace with current EQ issues and' perspectives. This may have been a contributor which led to the' programmatic breakdown in the EQ are Several significant EQ deficiencies were identified, both by NRC and the licensee, which affected many systems and component One safety deficiency involved extensive use of unqualified terminal blocks in instrumentation circuits inside containmen This concern resulted in shutdown of Unit 1 until necessary repairs in EQ circuits had been implemente Additional deficiencies with EQ equipment were also corrected while both

- plants were operating. . Deficiencies in the procurement area involved the purchase of commercial grade items for use in EQ applications. Additionally, the procurement program did not provide for the upgrade of equipment qualification in accordance with the requirements of 10 CFR 50.49(1). The potential violations identified are indicative of licensee management's previous lack of understanding of the issues surrounding equipment qualificatio Review of the licensee's response to IE Bulletin 85-03

"Motor-Operated Valve Common Mode Failures During Plant Transients Due to Improper Switch Settings", indicated that corporate managemer. was frequently involved in site activities

~

l and had a clear understanding of the issue. This is illustrated by the fact that a corporate representative had been temporarily assigned to Farley Nuclear Plant' to manage the IEB 85-03

, program, and that Corporate personnel were reviewing the

,

'

IEB 85-03 test results. The licensee's proposed resolutions to the bulletin have been acceptable; houver, supplemental responses were require The licensee's response to this bulletin have been especially extensive in the areas of actuator thermal overload selection and actuator motor inspection The licensee demonstrated excellent engineering capability in evaluation and repair of the crack in a 6-inch safety injection

which led to the finding of .the pipe-crack, to the final evaluation of the probable cause of the crack, the licensee conducted a well-thought-out analysis of the problem; followed by a comprehensive repair program. The licensee took the initiative to have the technical support people at the site maintain a daily dialogue with the RII Engineering Branch staf This commun' cation at the technical level assisted the NRC in the evaluation of the significance of the event, and also enabled the Region and NRR t.o coordinate the NRC coverage at the  ;

site and at the Westinghouse iaboratory where the failed pipe was examined. The use of sound engineering practice in the

. systematic evaluation of the probable causes of the pipe failure, and the systematic review of the other similar safety injection piping in both Farley units, enabled the licensee and NRC to conclude with confidence that the cause of the failure had been identified and that Unit I could be safely operated until the next regularly schedule outag Licensee's handling of certain IE Notices was not always in a -

timely manner. IENs that did not recommend corrective actions were quickly closed out. Those that did recommend corrective action were not closed out in a timely manner. This had led to a backlog of appror lately 78 incomplete IEN's with one IEN (83-56) dating back to 1983. The licensee did appear to have an ,

effective tracking system so that IEN status could be easily identified.

, The relationship between the site engineering groups ana corporate engineering has been good. While the corporate engineering staff has been limited in size (there were approxi-mately 35 engineers), the licensee maintained contract personnel on 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> call.

On December 29, 1986 the last of the several requested exemptions to Appendix R areas Fire Protection for Unit 2 and shared Unit I creas was grante Investigation and Allegations Review Office of Investigations are reviewing a 1985 allegation of health physics related problem Enforcement History During this SALP period, 59 inspections resulted in violations as shown in Section One severity level III violation and two severity level 4III problems were identified. The Severity Level III violation involved failures to adequately control access to a high radiation area, failures to comply with procedures for access control to radiation areas including a radiation work permit system, and failure to adequately instruct individuals on the limitations and precautions for working in or frequenting a restricted area. Due to the prior good performance in this area the Severity Level III violation was' issued without a civil penalt The remaining two Severity Level III problems were regarding the implementation of the procurement and vendor interface program. The licensee denied part of each problem. A $50,000 civil penalty has been proposed for the two Severity Level III problem Two other potential enforcement cases are being considered on EQ and hydrogen buildup in the charging pump /RHR system piping. Confirmation of Action letters were issued on October 6, 1987, for Unit 2 and December 2, 1987 for Unit I regarding equipment qualification issue Enforcement Conferences Held During Appraisal Period Enforcement Conference at Region II relating to the equipment qualification issues - 3/15/88 , Enforcement Conf erence at Region 11 relating to the Potential Overexposure - 2/17/88 3.' Enforcement Conference at Region 11 relating to the Procurement and vendor interface program - 9/3/87 Enforcement Conference at Region II relating to the misposi-tioning of the RHR suction isolation valve - 2/10/87 Enforcement Conference at Region II relating to shipment of contaminated snubbers - 12/22/86 Licensee Event Reports (LERs)

During the assessment period, there were 39 LERs reported for Unit 1 and 17 LERs reported for Unit The LER reports were thorough, i

sections typically included specific details of the event such as valve identification numbers, model numbers, number of cperable redundant systems, the date of completion of repairs to provide a

good understanding of the even .

'

LERs presented the event information in an organized pt.ttern with l separating headings and specific infor: nation in each section that led to a clear understanding of the event information. previous similar occurrences were properly referenced in the LERs as applicabl '

The licensee updated seme LERs during the assessment period. The updated LERs provided new information and the portion of .*he report that was revised was denoted by a vertical line in the right hand margin so the new information could easily be determined by the i reade .

The licensee submitted several reports and updates on a voluntary l basis during the assessment period. As stated on page 10 of NUREG- '

1022, licensees are encouraged to report any event that does not meet 3 reporting criteria if the licensee believes that the event might be [

of safety significance, might be of generic interest or concern, or [

contains a lesson to be learne i A review of LERs does not in general indicate any trend that the plants are subject to recurring problems. Recently the licensee ,

has developed a program to trend personnel errors and repetitive ;

equipment failures. The OPA team noted that all corrective actions taken were not listed in the LER and therefore, were not always correc Licensee evaluations did not always show that the root cause was trended or pursue The distribution of the events analyzed by cause by the licensee were as follows: ,

The high flux rate on N-41 was caused by the failure of the 1A inverter which supplies power to N-4 The unit returned to power operation on 01/23/8 Subsequently, the 1A inverter was tested and four blown fuses were replaced.

Surveillance testing was in progress on the 1-2A diesel generator and the diesel generator was connected to the IF 4160 volt bus. Upon comple-tion of the surveillance, the operator intended to .

'

open the diesel generator output breaker. However, he inadvertently opened the breaker which supplies power to the 1H 4160 volt bus. This' caused deenergization of the load center which powers the AC oil pumps for both steam generator feed pumps. The DC oil pumps for both feedwater pumps started and provided oil to the feed pumps bearing By design, the DC oil pumps do not supply control oil. Thus, the feedwater pumps -

tripped. The loss of feedwater ficw led to the reactor trip.

08/04/86 The reactor tripped from 99?4 power when both trains of the solid state protection system (SSPS) received indication of a "Genera.1 Warning". A general warning existed on the A train because the A train reactor trip bypass breaker had been closed as part of a SSPS operability testing. When the A train reactor trip bypass breaker was opened, SSpS momentarily received a ,

general warning on the B train due to a faulty secondary disconnecting contact on the B train reactor trip bypass breaker. General warnings on both trains t caused the reactor to tri The secondary discon-necting contacts for both the reactor trip and the  ;

reactor trip bypass breakers have been replaced as
