Purpose'and Overview The Systematic Assessment of Licensee Performance (SALP) is an inte--

grated NRC staff effort to collect the available observations and data on a periodic basis and to. evaluate licensee performance based

'upon this information. The SALP program is supplemental'to normal regulatory processes used to ensure compliance to NRC rules and regulations. SALP is intended to be sufficiently diagnostic in order to provide a rational basis for allocating NRC resources and to provide meaningful guidance to the licensee's management.to promote quality and safety of plant operatio An NRC SALP Board, composed of the staff members listed below, met on December 11, 1986, to review the collection of performance observa-tions=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_ safet performance at the Salem Generating Station for the period October 1, 1985 through September 30, 1986. The summary findings and totals reflect the twelve month assessment perio SALP Board Members Board W. Kane, Director, Division of Reactor Projects, Chairman S.

2 BACKGROUND C.1 Licensee Activities Both Salem units.have achieved availability _ factors well above the national average (68.5%) during the assessment period. For the period through August of 1986, Unit I was available 82% of the time, and Unit 2 was available 90% of the time. The Salem Units historically have experienced high forced outage rate The lifetime forced outage rate for Unit 1 is about 27%, and for Unit 2 about 35%. This has improved in most recent years. In-1985, Unit I was operated with an availability of 95.3% while surpassing the U.S. record for c .nual gross generation by a nuclear uni Unit 1 Unit 1 began the assessment period operating at 100% powe On October 6, 1985, the unit tripped when a senior shift supervisor opened the vent line resulting in a condenser low vacuum signal during troubleshooting of a condenser vacuum sensing device. This trip ended the unit's longest continuous run at_278 days. The plant then entered a 16 day outage to per-form maintenance and testing activities. The October 21, 1985, unit startup was terminated because a control rod could not be fully withdrawn from the core. The control rod connectors were repaired and, on October 22, 1985, the unit was returned to 100%

powe On December 16, 1985, the unit surpassed nine million megawatt hours electrical generation, establishing a new United States

. record for gross electrical generation in a calendar yea The unit tripped from 100% power on January 16, 1986, when_an equipment operator closed a breaker cabinet door too hard caus-ing 1A vital bus to trip and shutdown control rod banks C and D to drop into the core resulting in a high negative neutron flux rate trip. On January 31, 1986, the unit tripped from 100%

power due to No.11 Steam Generator (SG) Low Feedwater Flow -

Low Level caused by a malfunction of feed regulating valve 11BF19. On February 4, 1986, the turbine was taken off line to repair a lube oil leak en the lube oil regulating valve to No. 4 bearing. The plant was maintained in Mode 2 during the repair The unit tripped from 100% power on February 20, 1986, due to No.14 Steam Generator Low Feedwater Flow - Low Level caused by a broken electrical connection to the solenoid valve resulting in loss of air to feed regulating valve 14BF19. The electrical

.

connections on all four feed regulating valves were replaced and the unit was returned to power on February 21, 198 . . . - _ _ . _ . _ . _ , _ _ _ _ _ _ _ , _ ._

On March 21,-1986,- the unit was taken off line for .its sixth'

'

refueling outage. Replacement of three moisture separator

'

reheaters, upgrade of condensate pumps, 45 design ~ changes, a'nd

. reduction:of the backlog of outage-related maintenance work ~

r requests were accomplished during the 46 day outage. The_ unit'

was returned to service on May 6,1986. Subsequently, .the unit tripped from 9S% power on May 1, 2 ,1986, due to No.114 Steam Generator Low Feedwater Flow - Low Level as a result of a . limit switch going off its normally closed position.and the subsequent

,

' loss of both main feedwater pumps. On June 6, 1986, the unit '

!

.

tripped from.100% power due to the failure of the auxiliary power transformer (APT) and resulting actuation of the generator i

protection system. -The unit returned to power on June 7, but'

was limited to 90%_ power due to loading restraints'on Nos. 11 and 12 station power transformers. On June 12, 1986, the-unit tripped due to a feed flow / steam flow mismatch in conjunction i n

'

with a No. 13 Steam Generator low level signal. . The cause was a1 _

'

=

feedwater heater control PC board that became wet due to rain

'

and the. cabinet door being left openoto facilitate test leads usedifor testing following the. refueling outage. Resulting L' _ false signals. led to faulty feedwater system response and _

'

eventual tripping of No. 11 feedwater pump. During theLensuing

restart on June 13, 1986, following the unit synchronization, i

the unit; tripped while shifting the turbine' lube oil cooler On July 21,'1986, the -licensee initiated a normal . shutdown of

~

the unit to inspect and repair a main generator hydrogen leak' ,

into the stator water cooling system. The unit returned to

service on July 29 and operated until August 5, 1986,~when the i

I unit tripped on No.12 Steam Generator (SG) Low Low Level due to the loss of No. 11 SG feed pump caused by a failed suppression  !

diode in the. Woodward governor circuit which resulted in an *

. overspeed condition. _During the August 6, 1986, startup, the >

unit tripped from 35% on No. 11 Steam Generator low flow in-i - conjunction with-Nos. 11 and 13 SG low level. This condition-

! resulted from No. 12 SG feedwater pump sustaining a runback l

,

during troubleshooting on No. 11 SG feed pump. Also on August

'

6, the licensee identified an environmental qualification dis-crepancy in wiring for Limitorque motor operators and placed the

'

-unit.in cold shutdown to replace the wires. On August 12, 1986 the unit-was returned to 100% power.

+ On September 2, 1986, limited loading requirements on the

station power transformers (SPT) were imposed as a result of the Unit 2 reactor trip, safety injection, false loss of offsite h power event of August 26, 1986. The unit was placed in hot

): shutdown on September 17, 1986, to repair a steam leak on high pressure turbine-cold reheat piping to the moisture separator i reheater and reheat steam system. The unit was returned to

- power on September 24, 1986.

Unit 2

.

Unit 2 began the SALP period operating at 100% powe On October 7, 1985, the unit tripped from 100% power due to a momentary ground on "C" vital bus caused by an I&C technician performing surveillance on the bus. On October 30, 1985, the licensee declared an unusual event and commenced a controlled shutdown to repair a weld crack on a charging system instrument line which rendered both charging pumps inoperable. The unit was taken to hot shutdown on December 10, 1985, (Mode 4) t repair high pressure turbine steam line leaks and seat leakage from main steam safety valves. On December 19, the unit was taken to cold shutdown (Mode 5) to repair leaks on Nos. 21 and 23 Reactor Coolant pumps (RCP) seals. The unit-returned to power on January 5, 1986. Again, on January 19, 1986, a controlled shutdown and cooldowa (Mode 5) was performed to replace Nos. 22 and 24 RCP seals due to excessive leakage. The unit returned to power on February 3,198 On April 16, 1986, the unit tripped on No. 23 Steam Generator High-High Level as a result of a transient following loss of N Steam Generator Feed Pump (SGFP) due to an accumulation of water in the control oil. On May 2, 1986, a controlled shutdown was initiated to perform environmental equipment qualification inspection in containment. The unit returned to power on May The unit tripped on July 14, 1986, due to the loss of No. 2B Vital Instrument Bus Inverter, which caused a false reactor trip signal. Following inverter repair, unit startup was commenced on July 15. During the startup, a reactor trip occurred as a result of a voltage spike on No. 2B Vital Instrument Bus caused by personnel error during testing of the instrument inverte The unit was synchronized on July 16. However, later that day, a reactor trip occurred on No. 23 Steam Generator High-High Level as a result of governor control problems on No. 21 SGF Following repairs, the unit returned to service on July 20,

,

198 The unit was placed in cold shutdown (Mode 5) from August 6-14, 1986, to replace Limitorque motor operator wiring to correct an environmental qualification discrepanc On August 26,,1986, I&C troubleshooting activities caused spuri-ous signals in the Solid State Protection System (SSPS) result-ing in a reactor trip and safety injection (SI). This event was compounded by a false loss of offsite power (" blackout") signal that resulted when, during vital bus transfers between station power transformers (SPT), 2 of 3 vital busses were momentarily unpowered coincidentally. Following the event, as a result of commitments made at an NRC/ licensee meeting on August 30, 1986, and in a licensee justification dated August 31, 1986 for

. .

restart of Unit 2 and' continued operation of Unit 1, NRC granted permission for restart of Unit 2 and for continued operation of Unit 1. The commitments consisted of limiting loading on the station _ power transformers, powering the group busses from the SPTs, and performing additional analyses on the electrical system. On_ September 1,.1986, the unit was returned to powe On September 11, 1986, the unit tripped on loss of Nos. 22 and'

.

23 Reactor Coolant Pumps due to the deenergizing of-2F and 2G non-vital (group) busses caused by an electrical short on a non-vital transformer coincident with an internal failure of No. 22 Station Power Transformer. Spare transformers were installed and the unit returned to power on September 28, 1986.

- Inspection Activities An NRC senior resident inspector was assigned for the entire assess-ment period; a resident inspector was assigned in July, 1986. The total NRC inspection effort for the period was 2679 hours0.031 days <br />0.744 hours <br />0.00443 weeks <br />0.00102 months <br /> (resident and region-based). Table 2 (Inspection Hour Summary) shows inspec-tion time distribution in each of the appraisal functional area During the period, two NRC team inspections were conducted in the following areas: Environmental qualification of electrical equipmen Special inspection of the false loss of offsite power event of August 26, 198 An NRC Emergency Preparedness inspection team observed the annual emergency exercise on September 16, 198 Tabulations of Inspection Activities and Violations are attached as Tables 1 and 3, respectivel This report also discusses " Training and Qualification Effectiveness" and " Assurance of Quality" as separate functional areas. Although these topics, in themselves, are assessed in the other functional areas through their use as evaluation criteria, the two areas provide ;

a synopsis. For example, quality assurance effectiveness has been assessed on a day-to-day basis by resident inspectors and as an

'

integral aspect of specialist inspections. Although quality work is the responsibility of every employee, one of the management tools to

<

measure this effectiveness is reliance on quality assurance inspec-tions and audits. Other major factors that influence quality, such as involvement of first-line supervision, safety committees, and work attitudes, are discussed in each functional are The topic of fire protection is not discussed as a separate functional area in this assessment period because of insufficient inspection activity. The available observations on fire protection and house-keeping are included in the various relevant functional area .

II. CRITERIA Licensee performance is assessed in selected functional area Each func-tional area represents areas significant to nuclear safety and the environment, and are normal programmatic areas. The following evaluation criteria were used, as appropriate, to assess each area: Management involvement and control in assuring qualit . Approach to resolution of technical issues from a safety standpoin . Responsiveness to NRC initiative . Enforcement histor . Reporting and analysis of reportable event . Staffing (including management). Training effectiveness and qualificatio Based upon the SALP Board assessment each functional area evaluated is classified into one of three performance categorie The definitions of these performance categories are:

Category 1: Reduced NRC attention may be appropriate. Licensee manage-ment attention and involvement are aggressive and oriented toward nuclear safety; licensee resources are ample and effectively used such that a high level of performance with respect to operational safety or ccnstruction is being achieve Category 2: NRC attention should be maintained at normal level Licen-see management attention and involvement are evident and are concerned with nuclear safety; licensee resources are adequate and are reasonably effective such that satisfactory performance with respect to operational safety or construction is being achieve Category 3: Both NRC and licensee attention should be increased. Licen-see management attention or involvement is acceptable and considers nuclear safety, but weaknesses are evident; licensee resources appear strained or not effectively used such that minimally satisfactory perform-ance with respect to operational safety or construction is being achieve .

..-

~

Trend: .The SALP Board may determine to include an appraisal of the performance trend of a functional area. Normally, this performance. trend will only be used where both a definite trend of performance is discernible to the Board and the Board believes that continuation of the trend will result in a change of .

performance leve 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 .

The root cause analyses following plant occurrences are now being performed in more depth. These analyses and investigations have been successful in identifying and _ correcting the causes of

events leading to trips and plant safety concerns. Employee-r - management relationships have improved. Outage planning and perform-ance have become more structured as evidenced by the more timely completions of outage I

,',

There,have-been a number of identified perscr,nel errors. The programs in pivce seem to be sound and have identified problems that were caused or, missed by personnel performing operations, surveillance or trouble-snooting activities. There have been a number of identified const-

, ruction deficiencies and equipment failures that have led to plant problems. The majority of these were the result of balance of plant problems. Although the engineering support to the station has improved we acknowledge that you have identified, through a contractor, that additional concerns within the engineering organization need correctio "Is'. '

- The above listed observations are further amplified within the speci-

'

fic sections of this repor You have continued to operate a safe and efficient facility. You have developed effective programs to operate the facility and should continue to refine those programs with specific emphasis on addressing the personnel errors and construction / material deficiencies that were identified during this evaluation period.

O S -ities- by the licensee-when dealing ~ with plant- operations. , Reviews, decisions and corrective actions are clear, timely and in keepi '

with'NRC and; industry standards. _Often the corrections to identified concerns,and procedural policies presented by the licensee _ exceed the requirement The licensee's new organization, which was in place at the beginning of:this evaluation-period,; emphasizes plant operation with a focus on responsibility, accountability and ownership. Management has esta-blished new standards for the nuclear department with emphasis on

. goals and objectives for all management positions as far-down 'as the-engineer level as part of their performance ratings. Personnel are

>then graded on the results of their performance. Additionally, a strong emphasis has been placed on control of radiation exposure in day-to-day activities as well as outages. There has been very good

_

success in this area. (Refer to Section B of this report.)

The SORC (Station Operations Review Committee) continues to be a strong influence on operations. The meetings are focused on plant safety and integration of the new issues into the overall operations of the facility. All reactor trips and their cause and analysis are reviewed and concurred in by the SORC prior to unit startup. The committee stresses root cause analysis of the trips and considers refinements that should be taken to prevent recurrence. During the 4 review of the events which surrounded a reactor trip with an accomp-anying electrical fault in the switchyard that ' led to a false black-j out signal, the SORC organized a series of task forces to focus on ,

,

the cause and analysis of the event. These task forces analyzed the t event, identified cause and effect and presented their findings to

! the SORC prior to restart.

.

lwith regard to a long-standing item which management had failed to

-

.

. correct that led to a plant trip. The event began.when the operators

.

tied closed a limit switch, that in the past has been identified as a >

contributor.to plant' trips. LThe breaking of the tie down line initi-ate'd the trip'because the. limit switch opened. ~The concern has-been resolved.and licensee communications with all parties have reiterated

, management policy on the consequences of bypassing limit switche Long-standing-fire protection issues referred to in the last assess-ment period, such as a continuous action statement in effect because

,

of improper, broken or otherwise disabled ' fire doors, improperly installed fire ' dampers, and deficiencies within the sprinkler and

_

detection system have been corrected. A new fire chief has been  :

hired and the staffing of-the on site protection organization is

considered to be adequate. The licensee has identified several '

problems within the. fire-protection program-that led to a violatio The-responses correcting the problem, which included the use of fire watches and identification of technical specification related doors, was generally timely and no additional' problems of this nature have

been identified. However, the licensee is still identifying concerns within_the fire. protection program . Actions have been taken to

.

correct the identification of~ fire barriers that are not readily

[

'

. identifiable without special markings. In general, the fire protec-tion program has improved; and, the current staff is identifying deficiercies that have always existed within the program but had not been previously detected.

Housekeeping at the facility has improved. The good material appear-ance in all areas of the facility is readily apparen In the auxil-

'

f ary building, the radiologically controlled areas have been reduced

, and the material appearance has significantly improved. Ground water i in-leakage has been addressed and virtually eliminated. The licensee has a full time staff devoted to plant material condition and clean-liness. Most of the facility has been painted (utilizing a color

, coding scheme) and a component identification program is underwa The appearance, cleanliness, and condition of the facility is consi-dered to-be outstanding.

During this assessment period, the licensee has been very responsive to NRC initiatives, including closing out old NRC open items by dedi-cating a staff to work with the resident inspector to address these

. items. The licensee (all major departments) conducts quarterly i

,r 13 meetings with the resident inspectors to address future initiatives, current events and programmatic changes. The licensee has a strong Licensee Event Report (LER) reporting system. Thirty-eight nonsecurity events were reported'for the station during this reporting period in accordance with 10 CFR 50.72 procedures. Twenty LERs regarding Unit 1, and eleven LERs regarding Unit 2 were submitted in accordance with 10 CFR 50.73. A summary of these event reports is found in Tables 4 and 5 of this repor In addition, based on a limited sample review, the NRC Office for Analysis and Evaluation of Operational Data concluded that the Salem Generating Station LERs were of a very high qualit The licensee met with NRC Region I on two occasions during this period. On May 6,1986, a meeting prompted by the last SALP dealt with the licensee's initiatives for trip. reduction at the Salem Station. (The trip analysis for-this period is discussed later in-this section.) On August 26, 1986, a meeting was held to discuss the

' licensee's intentions-regarding the restart of Unit 2 following a reactor trip and safety injection with an accompanying false loss of offsite power _ signa The licensee has been responsive to identified plant conditions that warrant plant shutdown. Without hesitation, on five occasions, rela-ting to Environmental Qualification and plant degraded conditions, the licensee placed the units in a condition to expedite repairs. In several cases the units were brought to the cold shutdown conditio An above average number of trips (18) continued to be evident at Salem Station. Six of these trips are attributable to operator error. Although the errors are not causally linked, they are avoid-able trips that should be addressed by the license The mean trip rates per 1,000 critical hours, for the units are for Unit 1 and 1.1 for Unit 2. The rates attained for both units are above the 1985 average for Westinghouse plants which was about 1.0 per 1,000 critical hour The overall staffing of the facility is essentially complete. There are several proposed new positions which are currently being evalu-ated and filled within station engineering, site protection (fire protection) and radiation protection departments. During this assessment period, a new President and Chief Operating Officer was selected, a Senior Vice President position was eliminated, the oper-ations engineer was replaced, and a radiation protection engineer was hired. The organizational changes are designed to remove some of the management chain between the higher levels of the organization and the individuals actually performing the work. This change is intended to improve direct communication In summary, the licensee exhibits consistent evidence of prior plan-ning and assignment of prioritie Decision making is consistent at all levels. Reviews are generally timely, thorough and technically sound. Corrective actions taken are effective and thoroughly address the root cause. The licensee has an aggressive approach to the

.

.'

problems-encountered in the operation of a nuclear facility and is generally effective, timely and thorough with regard to overall

management is substantial. The contract for the major refueling work included a limit for total exposure with financial penalties if the specification was exceeded. The stem packing on approximately 400 valves was replaced with a low leakage design that will reduce main-tenance requirements in radiation areas and minimize contaminated area ,

The management review of an entry by two personnel into the reactor sump area while the flux thimbles were withdrawn, creating very high radiation levels, was thorough and technically sound from a radiation protection perspective. However, the licensee was requested to review the breakdown in controls afforded by the operations shift-supervisors. A review of licensee action plans indicates that the response to this NRC initiative will involve sweeping changes involv-ing most station departments in an attempt to permanently prevent a similar event from recurrin The radiation protection department has demonstrated a consistent ability to resolve technical issues from a safety standpoint. The major effort and expense to improve the effectiveness of the control point was already discussed. The Radiation Protection Manager has established the policy that no tools or equipment are allowed to leave the controlled area in order to reduce the amount of material brought into the area. The radwaste department found that signifi-cant exposure occurred to personnel attaching the lid on a waste container. A new tool was designed and fabricated to reduce such exposur 'The RP department staff was expanded during the latter part of the previous assessment period. All of the key positions were filled by qualified and experienced personnel within a reasonable tim Certain programs in common with Hope Creek station such as personnel dosimetry, respiratory protection training, and whole body counting have been transferred to the corporate RP staff. The station RP staff can now concentrate on the day-to-day and outage activitie Improvements in the training program have resulted in improved under-standing of the work and adherence to procedures. A screening exam is now administered to contractor technicians hired for outage support to verify their understanding of basic regulations. A prac-tical factors portion has also been added for senior contractor tech-nicians to demonstrate the plant-specific RP techniques in use at Salem Station. The training department staff is given in plant assignments during the outage to provide first hand experience and give a good understanding of training need .__ _ _ .__ _ _ ._ _ _

infrequent intercomparisons with the licensee's participating labor-atories. Although several of these weaknesses were brought to the licensee's attention by contractor audits in August 1984, December 1984, and May 1985, timely improvements in quality control were not provided. The licensee's corrective action system apparently failed to adequately evaluate and correct the weaknesses noted in the vendor audits. The licensee possesses an ion chromatograph that can meet the sensitivity requirements for the anion analyses; but, the licen-see has not aggressively pursued the use of this instrumen In the beginning of the assessment period, inadequate control of procedure changes was demonstrated when changes in chemistry proce-

In another event, inadequate procedures resulted in oxygen concentra-tions in excess of Technical Specification limits in two Waste Gas Decay Tanks. These events suggest that the problem with the control of procedure changes as was noted during the previous assessment period, also occurred early in this period. However, these problems were resolved during this period and the events have not recurre In summary, the licensee's radiological control program continues to be effective and procedural enhancements are currently being resolved with implementation scheduled prior to the 1987 Refueling Outage.

Also, the previous

SALP was based primarily on the day-to-day observations of the resi-dent inspectors. This SALP, similarly was based on observations by the resident inspectors; however, a programmatic inspection by region-based inspectors was also conducte The last SALP identified a concern involving an increasing backlog of maintenance work requests in conjunction with the elimination of contract maintenance personnel. During this assessment period, the backlog has been reduced to a manageable, constant number by licensee maintenance personnel with safety related work requests being addres-sed as top priority. The internal planning organization within the maintenance department plans the work and work requirements includ-ing: post maintenance testing, special instructions, tools needed, manpower and procedure requirements. The maintenance worker then is only tasked with the actual work and documentatio The maintenance work order system is now totally computerized and includes the scheduling of preventive maintenance, surveillance tests, and environmental qualification type preventative maintenanc Overall, this system has allowed the licensee to prioritize the main-tenance work and to further refine the preventive maintenance progra This system is used in the planning, management, and control of main-tenance activitie With regard to record storage methods, an inspection of station records was conducted during this assessment period with no problems being identifie The control of activities, decision making on the part of management, and policy adherence has substantially improved because of the new alignment within the maintenance organization. The new alignment includes one manager and two engineers, one for mechanical and one for electrical and I&C. This change, in conjunction with the newly created system engineers, has contributed to a more " root cause" oriented troubleshooting approach to plant problems. This was evidenced in the troubleshooting of several feedwater pump problems that occurred on both units. Two trips during this period were attributed to maintenance related troubleshootin Maintenance support during outages is one of the contributing factors to timely completion of outages. During the outages, the maintenance department has been actively involved in two programs that have

...

T

proved very beneficial to the operability, dependability and safety of the units. They are: M0 VATS (Motor Operated Valves Analysis and Test System) which, when implemented, gives a more positive indica-tion as to the status of motor operated valves with respect to their settings for safety purposes; and the repacking of valves, both accessible and inaccessible, during operations. .The new packing consists of a live loaded special packing that has reduced the number of leaks in key safety related systems, and has also reduced the amount of man rem that had been previously expended in the repacking effort, especially in the-inaccessible areas (high radiation).

In summary, the Maintenance department'shows consistent evidence of .

prior planning and assignment of priorities. The management struc-ture is suited to the methods of performing maintenance in order to meet deadlines and resolve issues in a timely manner. During this assessment period there were no violations identified within this area. The Maintenance department has an adequate staff with each supervisor having 8 to 10 individuals assigned to him. There is almost no turnover of personnel and the experience level of personnel is hig . Conclusion Rating: Category 1 Trend: None 3. Board Recommendations -

- Analysis The. previous assessment identified a lack of strict adherence to procedures and an incorrect interpretation of RCS leakage classifi-cation. The assessment also acknowledged that both areas had bee corrected but adequate time had not elapsed to properly assess the-long-term result Surveillance tests performed by the licensee are the responsibility of several departments, depending on the type of surveillance. - The operations, maintenance, chemistry, and site protection departments participate in surveillance testing. This section addresses surveil-lance tests performed without reference to the particular department involve There has been no re'currence of RCS leakage identification or proce-dure adherence problems during this period. However, testing led'to two reactor trips directly' attributable to surveillance activitie Several surveillance tests were performed late because of lack of attention on the part of the responsible party. Several diesel

- surveillance tests were performed late (by as much as several hours)

by the operations department and chemistry sampling of waste holdup tanks, plant ventilation, and waste gas tanks was delayed due to procedural and personnel errors. About 2500 safety related surveillance tests are performed at the station per yea During a QA audit of the valves within the IST program, the licensee identified valves that required testing both in the IST program and for containment integrity testing. These valves were added to the proper surveillance tests and an assessment was performed on the valves that had been missed. No adverse conditions were identifie The containment valves were normally closed valves which were proven >

to be close .

There is evidence that the licensee has programs in place that comply with the technical specifications. These programs were the reason the licensee identified its own missed surveillance tests and omis-

, sion of valves on the surveillance program. The reviews of these programs, by the licensee, has identified the discrepancies in a timely manner for resolution. The problem with missed surveillance tests and troubleshooting practices by the licensee is not program related, but rather personnel related, indicating that more awareness on the part of plant personnel to prevent similar occurrer.ces is warranted.

That assessment was based on observation of the annual exercise. held on October 23, 1984, a followup inspection, and subsequent enforcement action. The deficiencies identified during the October 23, 1984 exercise were resolved. Evidence of this was verified during a team inspection on July 8-11, 1985. All of the deficiencies which resulted in the civil penalty were closed by the inspection team. All licensee nuclear activities have been relocated to the site area. A new Vice Presi-dent - Nuclear was selected and has placed a strong emphasis on emer-gency preparedness. A full-time emergency preparedness manager was assigned, the emergency training program has been substantially improved, and an attendance / record / qualification system put in plac During this assessment period, there were two announced inspections of emergency preparedness activities consisting of observation of two partial participation exercises conducted on December 4, 1985, and September 16, 1986. Licensee responsiveness to NRC initiatives was demonstrated by management attention and detailed corrective action The NRC scenario review and the licensee changes to the scenarios also fully satisfied NRC concerns. Each exercise scenario tested a major portion of the Event Classification Guide, the Emergency Plan, its implementing procedures, and provided an opportunity for licensee personnel to demonstrate areas previously identified by the NRC as needing corrective action. Areas identified during the preceding exercise were corrected and did not recur during the subsequent exer-cise. The licensee's staff correctly identified Emergency Action Levels, effected offsite notifications within the prescribed time, followed appropriate response procedures and formulated protective action recommendations. No significant deficiencies were identified and only a few areas for improvement were note The licensee is currently installing a state-of-the-art notification feedback system for offsite siren The Artificial Island generating station received FEMA 44 CFR 350 approval for Delaware state and local plans in January 1986 and submitted revised state and local plans for New Jersey on October 10, 1986 for FEMA RAC revie A commitment by management to strong emergency preparedness and training programs has been made by licensee management as evidenced by the quality of emergency response facilities and equipment, response of the licensee's staff during exercises, increase in staf-fing of the emergency preparedness group, and enhanced training acti-vities for the emergency preparedness staf . _ .

During this assessment period, the licensee completed the incorporation of Hope Creek into the security progra During this assessment period,, there was one unannounced physical protection inspection of the security program, a special inspection of the training and qualification program, and routine resident inspections performed throughout the period. No violations were identifie During this assessment period, NRC followed up on the licensee's commitments relative to deficiencies identified during an NRC Regula-tory Effectiveness Review (RER) which was conducted in 1982. The licensee promptly took corrective action on those deficiencies that could be immediately addressed. Many of the remaining corrective actions were of a long-term nature, including a major upgrading of security facilities, systems, and equipment and incorporation of the security program for the Hope Creek facility. Specific long-term -

actions included the construction of a new access control facility (opened October 1,1985), installation of a new integrated security computer system and associated hardware, computerized access control devices, state of-the-art assessment aids, and new personnel search equipment. The licensee's plans were developed and implemented ir, a thorough, organized manner. The security upgrade program was carried out in increments so that the activities would have a minimal adverse impact on the existing Salem security program. The licensee provided NRC with thorough and clear progress reports on the activities and

, promptly identified changes to schedule. The performance of the new systems and equipment has been sound and relatively maintenance free, after the initia? startup period. This performance results from the extensive design, procurement and engineering effort expended on the

.

project. The licensee rarely had to rely on the use of extensive human resources for compensatory measures while the upgrade project

was in progres Housekeeping of the access control facility and security facilities is noteworthy. The general state of cleanliness demonstrates a high degree of pride and morale on the part of the security force, f

Management's interest in establishing and maintaining a quality program is further evidenced by the high quality of performance indi-cated during a special NRC inspection of the security force training and qualification program that was conducted to determine the quality of the training program and to measure the ability of security personnel to carry out their assigned duties. The licensee has required its security force contractor to establish and maintain a ,

strong training program. The training is conducted by individuals who are experienced and assigned to security training only. Training facilities have adequate classroom space and good training aid Lesson plans are well developed, thorough, and kept current through feedback from ' supervisory personnel who perform on-the-job surveil-lance of performance. The results of the special inspection indica-ted that the security training program is broad in scope, of high quality, and administered in a highly professional manne The licensee's security plans, procedures, and instructions are clear, concise and thorough, Letters and reports submitted to NRC are also clear, promptly submitted, technically accurate and seldom generate questions from the NR Corporate security management is actively involved in the Region I Nuclear Security Organization and other nuclear industry groups engaged in security innovations and the development of security program standards. This is evidence of support of the security program at a high management level in the licensee's organizatio To provide for continued effectiveness of the security program, the licensee conducts in-house surveillances to monitor the performance of the security organization. Experienced and knowledgeable person-nel perform these surveillances and the results are aggressively pursued to ensure prompt and effective corrective action and feedback to the training program. These surveillances are conducted in addi-tion to the annual security program audit required by NR The security program is strongly supported by the other plant opera-ting divisions on site and frequent interface is evident. Security force personnel exhibit excellent morale because they are recognized and respected on site and they have been provided excellent security-related equipment in order to perform their function. As a result, they carry out their assigned duties and responsibilities in a professional and dedicated manne The licensee submitted two security event reports pursuant to 10 CFR 73.71(c) during the assessment period. Both events were bomb threats that were adequately responded to by the licensee and were subse-quently determined to be hoaxe y d'

During the assessment period, the licensee submitted complete revi-sions to the security and contingency plans in accordance with the

l 28 G. Outages and Engineering Support (8.7%, 232 hours0.00269 days <br />0.0644 hours <br />3.835979e-4 weeks <br />8.8276e-5 months <br />) Analysis During this assessment period there was a refueling outage (46 day duration), and 8 other outages resulting from unplanned shutdown (See Table 6 for detai's.)

The last SALP assessment discussed management changes which added a planning department reporting directly to the station manager. The assessment also illustrated the need to evaluate the new planning department and how it would function during outage During the above outages, pre planning and oversight by the planning department influenced the station's expedient completion of the i

outages within the time allotted. The licensee also conducted pre-planning meetings, held at least one per shift during outages, and post-outage critiq;es to discuss the need for improvements in future outages. At these meetings, the various departments are held accountable for their progress during the outage. Afterwards, the departments are responsible for refinements which could be made to enhance future outage During major outages, photographs of the outage managers, coordina-tors, department heads, contractor managers and coordinators are posted in a conspicuous place to aid site personnel in determining the proper contact for grievances or problems that develop. This has improved communication During the outages the following good practices were noted by the inspectors:

-

Supervisor and management presence at the work area Accountability for work performe QA and QC direct involvement where require Direct portable radio communication between the key management directors and contractors.

i All of the above have contributed to closely directed and responsible i outages that reflect prior planning, aggressive management, and

!

organized decision making.

l The licensee previously hir(J contractors for outages on a cost plus basis with the contractors supplying their own QA and QC. The licen-l see has now adopted a different approach to the control of contrac-

Q This practice brings about more thorough and complete design change packages in order to assist in preparing bid packages. The licensee has also attached monetary incentives and penalties for exposure goals. During the refueling, the incentive was, for Westinghouse to complete steam generator work, rewiring of the control rod drive assemblies on the reactor head, head removal and replacement, refueling, and reactor coolant pump seal work within 100 man rem. Westinghouse achieved this goal during the refueling outag Changes were made in engineering support during '

is assessment period. The Systems Engineering support organi; tion completed training and was assigned to the station. This organization, which reports directly to station management, is not yet fully implemente However, the department has provided a strengthening of root cause analysis, become involved in the day to day operations, and has a direct. input to the Design Change Requests and Safety Engineering Review Another change has been the establishment of a corporate engineering

" single point of contact" to the station which has opened the line of communication between the corporate engineering department and station operations. This communication difference has improved corporate support to the station and aided in the resolution of deft-ciencies identified during outage meetings. There has also been a concentrated effort in assuring the presence of sponsor engineers at the site. These engineers sponsor the design changes being instal-led. Disagreements and discrepancies are resolved in a timely manner and the design change packages are more complete from a documentation perspectiv Inspections were conducted for followup of degraded piping systems and their associated LER's. These inspections determined that management involvement was evident concerning actions taken following some 50 instances of degraded piping during the past six years. The licensee's resolution of these failures was technically sound and thorough. Extensive analysis and subsequent corrective actions taken or planned were ccmprehensive and documented through complete, well-maintained and available record Management involvement was not as evident with regard to followup of IE Bulletins 79-02 and 82-02. The licensee demonstrated a lack of effective followup to NRC concerns which were previously identified during an earlier review of the licensee response to IE Bulletin 79-02. In addition, the licensee's response to IE Bulletin 82-02 was incomplete, and inadequate quality assurance measures were also identified. For both of the IE Bulletins, records were not complete nor properly maintaine ..

4

Two additional areas of concern were identified in the engineering support area during this assessment period. They are 10 CFR 50.59 evaluation and environmental qualification (EQ). In the area of 50.59 evaluations, one of the reviews was not researched in suffici-ent depth to identify dynamic loading of the station electrical system which led to significant electrical problems. However, this was the only problem area identified during the review of 10 CFR 50.59 evaluations. With regard to this issue, the licensee took immediate effective corrective action and has committed to a long term program to reanalyze the station loading. In addition, the licensee has met with the staff on several occasions to discuss their analysis and longer term corrective action programs. With regard to environmental qualification, it appears that not enough resources were devoted to the effort both in the completeness of records and staffing. While the plant site staffing was adequate, the engineer-ing staff devoted to EQ was minimal as demonstrated by only two dedi-cated engineers to support the EQ effor The Engineering Department has self-identified the need for further improvement and contracted an independent evaluation of the depart-ment with the following results;

-

3 In summary, outages have been pre planned with definite priorities and emphasis on timely completion; controlled, using knowledgeable personnel; and, completed within the time constraints of the sche-dule. The Engineering Department has demonstrated evidence of prior planning and assessment of priorities, has generally provided timely responses to NRC and industry concerns and has performed a self-initiated program evaluation designed to improve the department's effectiveness.

H. Licensing Activities (NA) Analysis During the previous assessment period, the licensee was rated as Category The two areas that had the most adverse impact on performance were the long delays in processing licensing actions and realignments in the licensee's staf 'During this SALP evaluation period, the licensee has shown good management overview in the area of licensing activities. This was especially evident through the timely submittal and subsequent approval of several license amendments in anticipation of improving cycle reload efficiency for Unit The ifcensee's management demon-strated active participation in licensing activities, and kept abreast of current and prospective licensing actions. During the rating period, a system for prioritizing both the licensee and the NRC action items was formally initiate The ifcensee's submittals are usually timely. However, in many instances additional information or revisions are necessary before review can be completed. This occurs most often in the area of plant-specific licensing actions. The licensee's treatment of the no significant hazards standards of 10 CFR 50.92 has shown steady improvement, and is almost always adequate. In some cases, the licensee needed to provide more detai The licensee maintains a significant technical capability in almost all engineering and scientific disciplines necessary to resolve items of concern to the NRC and the license In addition, the licensee utilizes the services of other nuclear support groups to assist in the resolution of technical problems or to utilize new and proven techniques that will enhance the operation and safety of the plan The licensee's good technical capability is reflected in the submit-tais made in support of, or in response to, licensee or NRC initiated actions. The licensee, though, does not always provide all of the information necessary to complete a review without requests for addi-tional information. However, few licensee responses to NRC requests for additional information required subsequent questions. Also, during the staff review of several safety issues, the licensee requested meetings with the staff in anticipation of review diffi-culties, thereby eliminating delay The licensee has been responsive to NRC initiatives in many instan-ces. Schedules are negotiated with the licensee based on prioritie The licensee has had difficulty meeting many of these negotiated schedules. However, these schedular delays seem to be more a resource management problem than a responsiveness problem. The licensee appears to be more responsive to those items for which it

r-e

has placed a high priority rather than those for which the NRC has indicated a high priority. As discussed earlier, a new policy has been formalized whereby both the licensee and the NRC agree on prior-itization of certain licensing actions. This has helped alleviate some of the past problems in this are The licensing group has exhibited a high degree of cooperation with the NRC staff. The good communication between the licensing group and the NRC has been beneficial to both in the processing of licens-ing actions. Areas of expertise are well defined within the grou In addition, the group does an excellent job of coordinating the effort when input is required from the different groups within Public Service Electric and Gas Compan The licensing group holds informal training sessions on topics of current and future interest. The group also participates in corpor-atewide training program, and participates in industrywide training programs provided by various organization In addition, the licen--

see has a training simulator located at the sit The licensee's licensing activities are conducted by a well staffed, and well trained group resulting in an overall efficient operatio Management overview is evident in that the licensing groups is well integrated into other plant activities and licensing activities reflect a uniform approach. Upper management becomes involved in licensing actions when necessary to assist in resolving potential deadlocks. Further, during the reporting period, licensee manage-ment, in their continuing effort to improve their SALP rating, met with NRR management to discuss the issu In summary, one of the licensee's strengths appear to be in their approach to resolution of technical issues from a safety standpoin The licensee has extensive technical capability that is reflected in their submittals and discussions with the NRC. Another strength is in their staffing. The licensee continues to upgrade the experience, capability and effectiveness of the licensing group, and the support-ing administrative and technical personnel required to operate a good facility. However, greater licensee attention needs to be focussed on management involvement and control in assuring quality, where the licensee needs to put more emphasis on assuring that thorough details are provided in submittals in order that fewer iterations are required during the review process; and, responsiveness to NRC initi-atives, where the licensee needs to pay closer attention to submittal schedules in order that the number of short-term schedular slippages are reduce .,

Assurance of' Quality (NA) Analysis Assurance of Quality is a new separate functional area for this SALP period and is a summary assessment of management oversight and effectiveness in implementation of the quality assurance program and administrative controls affecting quality.- Activi-ties affecting.the assurance of quality as they apply specific-ally to a functional area are addressed under each of the sepa-rate functional ' areas. Consequently, this functional ~ area is not an assessment of the quality assurance department alone, but-is an overall evaluation of the effectiveness of management's initiatives, programs, and policies which affect or assure qual-it ,

Corporate and station managers are present and actively involved in station activities commensurate with their level of responsi-bilit They have displayed a thorough knowledge of plant issues, and decisions have been timely with a proper perspective on safety. For example, numerous elective plant outages were undertaken by the licensee during the assessment period to investigate and correct EQ deficiencies and random equipment malfunctions. Licensee investigation, evaluation and response to SG feed pump problems, electrical transformer faults, and the August 26, 1986 false loss of off site power event were thor-ough, timely, and technically adequat Two inspections were conducted during the assessment period to review the implementation of the' licensee's quality assurance (QA) program. The QA Department has demonstrated significant involvement with site activities. -QA/QC involvement with daily activities has been expanded and includes backshift coverag QA has expanded their valve and breaker surveillance program and has instituted an audit program to perform in-depth reviews and walkdowns of plant systems. Management support of QA involve-ment is evidenced by the allocation of personnel to support reorganization of the QA engineering department along with a complete rewrite of the department procedures manua Continuing personnel assignments and departmental realignments in maintenance, emergency planning, radiation protection, QA engineering, and fire protection indicate that management fore-thought and planning strive to enhance the departments' overall performance. Increased management attention is warranted in the chemistry department, however, as evidenced by weaknesses in the chemical and radiochemical quality control program including lack of control of chemical solutions which resulted in a viola-tion, delay in correcting identified technical issues, and continuing disagreements between laboratory comparison analyse ,

E*

.

Additionally, weaknesses identified in IE Bulletin followup and

'50.59 reviews indicate a need for management's attention in these area Cooperation between departments and between management and workers has improved significantly during this assessment period. Fire protection discrepancies caused by poor communica-tion between operations, site protection, and maintenance departments have been discussed and resulted in procedure changes. Training personnel are more integrated and involved with plant activities such as being coordinators for outage activities.and reviewing LERs for lessons learned. Senior Shift Supervisors are cycled through the training department as instructors for two year periods. The licensee has institute "On-the-job" Team (0]T) Evaluations" in which representatives from management, supervisory, and bargaining unit ranks period-ically form a team and critique selected station activities. A central planning and work control center located outside the control rooms is in the initial stages of implementation and is a joint effort of the planning, operations, and maintenance department The licensee has exhibited aggressive and effective self-assess-ment programs. The DJT evaluations noted above are one exampl QA department audits identified IST and containment integrity surveillance deficiencies which resulted in improvements in these areas. The security and fire protection staffs have conducted in-house surveillances which have identified and resulted in the correction of deficiencies. The Engineering and Plant Betterment department initiated two self-identification program near the end of the SALP period, to improve the depart-ment's effectiveness. Results will be assessed in future SALP Licensee initiatives in planning and job activity control have proven effective in successful completion of outages and in meeting occupational exposure goal Innovative programs such as fixed price contracts for outage work and incentives for achievement of exposure goals are indicative of licensee initi-ative Programs to promote quality awareness and employee involvement have been instituted during this SALP period and appear to be well received by station personnel. Examples of these programs are:

-

Plant Material Improvement Programs which include cleanup, painting, and labeling activities in the plan Employee Involvement Program facilitates management / worker interfaces and awards for good performanc .

'5 Training and Qualificatioa Effectiveness (NA)

/ .

g Analysis This is a new functional area in this assessment period. In the

.

prior assessment period, training was discussed within each L

'

functional area and in the Section " Summary of Results." There f were no adverse findings identified during the last assessmeret perio The licensee operates and maintains well equipped training facilities which provide training for all of the nuclear depart-ments including operations, I&C technicians, electriciar,s,

,

mechanics, chemists, health physics te:hnicians, machinists, and P

welders. INP0 recognizes ten training areas at Salem and all ten areas have been accredited. The NRC performed a post-

. accreditation audit on the licensee's training program in June, 198 The report concluded, "that a strong management commit-x ment to training program improvement exists at Salem. Also, it is apparent that there is an effort to continually update and revise the training ptograms and task lists based on feedback and experience. ... Deficiencies identified ... are an incom-

'

plete task analysis ... for deriving learning objectives and a

^ failure to identify which tasks are appropriate for continuing

- training. The learning objectives at Salem were complete and easily traced to tasks and test items."

During this assessment period, Region I administered three exam-inations. In November, 1985, fifteen candidates were given writ-ten and simulator / oral examinations for initial licenses. Of the eight candidates for Senior Reactor Operator (SRO), one

.

failed the written exam and one failed the simulator / oral exam Of the seven candidates for Rea: tor Operator (RO), th-ee failed the written exam and two of thore three also failed the simula-tor /cral exams. In April,1986, one SR0 and three R0 candicates

'

from the November exam were reexamined. All received their license Overall, Salem continues to have a satisfactory program for the

, initial training of candidates; however, the failure rate on the

- November exam implies that the utility needs to better screen sthe candidates prior to the hRC examinatio One evaluation of the requalification program was made during this reporting period in September, 1986. The utility training staff submitted their written exams to the NRC for revie * Several questions were replacei by the NRC, and then the exam was administered to seven SR0's and five R0's. Six of the SRO's and all of the R0's passed the examination. The written

.

examination was graded by both the utility and by the NRC, and examination grades agreed within 5%. The one SR0 that failed-the-examination has subsequently passed another examinatio No simulator / oral examinations were given during the September portion of this year's requalification program. The requalif t-cation program was found to be adequate to ensure that.the oper-ators maintain the requisite knowledge for safe operation of the plan ;

Staffing is adequate as is the training and qualification effec-tiveness of the QA/QC staff. A full time QA department coordi- ,

nator has been assigned to the training center and is responsi- i ble for developing and maintaining QA portions of training *

programs. The operations department has assigned a Senior Shift Supervisor to the training department for a period of two years'.

Licensee management has stated that this is a pilot program and intends to rotate a new Senior Shift Supervisor into the train-ing department every two years. The purpose is to lend opera-tional expertise to the training department for operational training and to giee; Senior Shift Supervisors a change from shift work and the continuous pressure of operation Salem does not use a separate individual as a Shift Technical Advisor (STA). Instead, they have instituted a policy that at A least one of the SRO-licensed individuals on shift will have an engineering degree. This provides the flexibility for the indi-vidual who is technically most competent to also be the indivi-dual who is making the decision Training effectiveness fn the day-to-day operations should be

. reviewed by the licensee. When evaluating the types of operator and personnel errors at the facility, it appears that the train-ing received is excellent and personnel perform within the confines of that trainin However, the training department may need to expand training programs, especially in the area of

" troubleshooting", methodology of performing surveillance test-ing on a running unit,.and operator simulator training in the area of feedwater losses and plant recover . In summary, the training and qualification program makes a posi-tive contribution, commensurate with procedures and staffing with C modest number of personnel errors. There is a well defined program that is implemented for a large portion of the ,

staf Inadequate training has been identified as a root cause for several plant trips that have occurred during this assess-ment perio t

V. SUPPORTING DATA AND SUMMARIES

' Investigations and Allegations Review Three allegations were received, followed-up, and closed during this assessment period. The allegations involved (1) radiation protection program practices for laborers working in contaminated areas and bringing contractors on site as visitors if they fail the GET exam; (2) health physics concerns including working in reactor building at power, neutron doses and monitoring, and resulting health problems; and (3) decontamination work circumvented health physics procedures

,

and f alsification of radiation level reading All three allegations were found to be unsubstantiate Escalated Enforcement Actions Civil Penalties Non . Orders The order issued May 6, 1983 was rescinded on March 18, 198 . Confirmatory Action Letters Non Management Conferences Two management meetings were held during the assessment period. The first (May 6, 1986) was held as recommended in the last SALP and involved a licensee presentation of the comparison and analysis of Salem Unit I and Unit 2 trip historie The second (August 30,1986)

meeting was held regarding the false loss of offsite power event of August 26, 198 Licensee Event Reports (LERs)

Thirty-one LERs were submitted for the two Salem units during this period. The LERs are listed in Table 5. A causal analysis concluded that; twelve were due to personnel error and were related to reactor trips, six resulted from equipment failure and were also related to reactor trips. The analysis of these LERs is delineated in Table AE00 provided an evaluation of quality of Salem Generating Station LERs as part of the SALP process. AE00 concluded that the LERs reviewed were of a very high quality, additional details of this analysis were provided to the licensee by letter dated November 19,
