Subject:
Selen EPPR Scope Redaction Because of pending enforcement actions at both Setem and NC, 4 TTM's planned visit, the NC SALP, and other activities, the scope of the Mey 30 Setem EPPR has been redaced. TTM has agreed to limit the meeting itself to one hour. So, our discussion will have to be focused only on the " key" issues.
Per discussion with John and Dick Cooper, the following need to y be included in the EPPRI 1
' 1) PSA @ te to include recent inspections only. The full update of the PSR with the inspection findings and plant event attachments should proceed in the backgromd on a "not to interfere" bests with the planned elements ilsted below.
i 2) Senior Management Briefing paper I 3) Preliminary or finst findings from the Eselgroth 40500 team '
inspection currently mderway.
) 4) Proposed MIP that reflects our Insights from above i
i From my perspective, I believe there are three " key" (seues that
' need to be highlighted. First, Manan modJte confleuretion
, control. Many, if not ett of, the Ms 10 problems appear to stem from a lack of configuretton control with the Hagen radJtes. The j licensee also admits to many other problems in their recent ettegation response on this same s4 ject. Second, control and issuance of certe and stanolles from the warehouse and selv system appears to be at the root of a number of plant problems, such as, the recent problems with sW, pre planning for the turbine outage to fix the control volve limiter, and the instettetton of the wrong PORV Internels. Some of these problems seem to stem from the fact that the same part mmber (follo) is used (vice a mlque mmber) for the same part from many different suppliers or vendors. Third, and last, root cause anstysis l performed by system engineering continues to be week. See my 1 recent inspection (95 02) with Larry Schott and Ram shotle. I believe that we should consider these when planning future initiative inspections.

Unit 1 besen the period operating et 1001 power. On February 3, the Licensee initiated a
' mit shutdom to comply with plant Technical Specifications. During leptementation of a i
DCP to correct a problem with a solid state protection eyeten ($sPS) power feed, a j
rededent power ogply tripped. The licensee wee moble to fully restore SSPs to operability within the technical specification limiting condition for operation acti m statement allowed outese time. On February 4, the licensee entered Mode 5 (Cold shutdown) to addrese $$Ps concerne. On February 15, operators entered Mode 4 (Not shutdown). The q
ticensee maintained the unit in Mode 4 iAfte resolving problems encountered with main steen atmospheric relief volves (MS 10s). On February 27, operators commenced a reactor eterty.
On Merch 2, operatore increased power to 48%. On March 3, operatore reduced power to 28K to make a bloshield entry to adjust RCP oil levels. On March 8, operators increased power to 1005 and maintained the mit there for the remainder of the period.
]
I Unit 2 began the period in Mode 3 (Hot $tenchy). On February 1, operators commenced and completed a reactor startup. On February 3, operators commenced e Technical Specification j required shutdown from 15 power, following removat of WRC Enforcement Discretion due to potential common mode failure Of SSPS power supplies. The (feensee placed the unit in Mode j 5, completed trosleshooting and repelrs to sses, and commenced a plant startw. On February 11, operators took the reactor criticet and comunenced a power increase. On February 19, the licensee inittsted a shutdown from 475 power to remove the no. 21 Reactor i Coolant Ptap from service in response to low seat water Leekoff flow. The (feensee entered
- Mode 5, replaced the no. 1 seat on no. 21 RCP, and commenced a plant start w. On March 8, i
operatore achieved reactor criticality and commenced power escalation. The mit coupleted s the period at 905 power. .

e on February 3, 1995, e unit 1 main steem atmospheric relief (13Ms10) velve would not open in roeponse to maniputetton of centrote. On February 10, 1995, 22Ms10 would not respond in automatic to steen pressure above the pressure setpoint. These problems were the latest in j e tone history of events with M810 (and Nogen mochJte) performance probleme (including April l
7, 1994 event). The licensee did not initiate a thorough root cause until prompted by the reeldents and Regional management. A thorough root cause, perfonsed by a multi disciplinary i
a team, concluded that contributing factors included inadecpaste maintenance, vendor i
i l 4

refurbishment, design, control of parts, and operator m derstanding of design contributed to the performance problems. (It 95 02, not yet issued.)
e During tote January 1995, seles sought eNd wee granted e Notice of Enforceennt Discretion to address design deficiencies with the Solid State Protection System. Electrical coupersonts (e.g. Limit switches and pressure sensors) associated with main steem, turbine controls, and feedwater were susceptible to rendering all or most of SSPS inoperable based !
on a ainete high energy line break. Vnen mexpected power supply trips occurred during the i modifications, Region I withdrew enforcement discretion. l i
e on January 11, 1995, with Salem Unit 2 in Mode 4, the no. 23 RCP seat water return valve {
for the no. 1 seal closed, foolating seat flow. The licensee determined that the pressure !
j 1
diaphragm of the ASCO solenoid velve failed because of its extensive time-in service (about ;
20 years) coupled with the continuous air pressure applied at the diaphragm (about 80
'i psig). Plant staff planned to establish a periodic replacement sche ele for the J diaphrops. Westinghouse recosmonded that PSE&G inspect the no. 1 seal. For safety considerations (evoiding redwed inventory) Setem management, af ter consulting with Westinghouse and other licensees, elected to perform the maintenance by lowering the RCP I onto the "backseet" formed by resting the radial bearing on the thernet barrier heat exchanger. Selen meintonence coupleted the maintenance activity safely. Although they found no seal demose the licensee reptoced the no. 1 seal package.
e in January 1995, the inspectors learned that unit 2 operated the entire previous cycle 1
(5/o3 to 10/94) with a closed drain velve in a connon drain line for the Pressuriser Safety a Velve loop seats. The velve should have been opened, but the licensee had not done an edsquete post-modification linew or adequate post modification testing. The 10 settons of ,
l I
water in the loop seats would create thrust loading on the safety velve discharge piping 4
with the potential to deform the pipe, restricting flow. As a result, the loop seats could render the safety vetwee incapable of protecting the RCS from overpressurization. This issue is a candidate for escateted enforcement. (IR 95 02, not yet issued.)
e In December 1994 and January 1995, during startg from the refueling outage, Salem Unit 2 pressuriser code safetles teeked poet the seats se (apparently) to dead weight and theneet loading on the discherpe piping. As a reeutt, Sales spent the period from December 25, 1994 to January 10, 1995, determining the cause of the leakage. Sales replaced the code
! safeties, adjusted the piping, and, as of January 31, 1995, had successfully reached normat l
operating pressure with no code safety seet leakage. (IR 94 35) i e Stuck trash reke af fecting unit 1; occurred several times, em November 15, 1994, the new i

On December 7, 1994, the new reke again stuck on the old trash rocks in front of the 13e CW ptap intake, forcing a power reduction to 850 Mwe. On January 3, 1995, the new reke stuck in front of 12g CW pump. On January 9, 1995, the old reke stuck in front of the newly replaced rocks in front of 138 CW ptmp intoke. PSE&G replaced the

Although the Alternate Test Insertion (ATI) circuit had been turned on (see below) and had pro &ced portudic alorse, the techs and operators did not pursue the alarms ( & e to previous experience) and i apparently took a power reduction that could have been evolded. The licensee contracted an
- EMI specialist in mid-February to investigate the frequent ATI test faults. Engineering, steported by the EMI speciellet, determined that EMI tevels in the SEC cabinet, although high enough to cause ATI alarms, do not ispect the ability of the SEC to perform its

[
tine failure during en accident, could have (and at times would have) been less e
then assumed in the accident analysis (no vlotetton was issued, since satem was always in compliance with the Technical specifiestion requirements).
The Senior Resident Inspector has personally seen evidence that the alleger made the
! concerns known to the licensee and that the licensee did not respond in a timely, conservative fashion. Although some of the allegations from the same source were uns @stentiated, several more have yet to be addressed.
e The licensee discovered on October 15, 1994, 2 days into the unit 2 refueling outage, that a velve in the pressurlaer code safety velve loop seel drain Line had been closed throughout the operating cycle from July 1993 until October 1994. The lamediate safety laplication is that the licensee could not assure, based on any onelysis estating as of Merch 15, 1995, that the water hasumer from the impact of the water in the loop seal on the velve discherpe line would not deform the discharge pipe and restrict flow to less then that regaired by design. The licensee is currently performing an analysis to demonstrate that the velves could have performed their intended f metton, however, engineering stated that enelysis ullt not be able to show that the thrust loads will be within code ellowable timits.
e service Water (SW) Leeks: The licensee is completing a seven year pipe replacement project that will reptoce most (about 19,000 lineer feet are safety related) of the safety related SW piping with 65 moty steintess steel. This project will probably continue through 1997.
Currently, approximately 90% of the safety rotated portion of the project has been ;
completed, including the majority of the gW piping in contaltenent, diesel boys, SW intake '
structure, and auxiliary building. gesed on NaC inspection, SW pipe replacement project is ,
progressing satirfactority se scheduled.
e Unit 2 Sustained Operation of Greater Than 1005 Powers daring the recent outage, the licensee confinmed eroeien of the feedwater flow nogales resulting in incorrect entine colorimetric data. Upon discovery, ticensee famediately reduced power for both units, and began adjusting instrument setpoints to insure conservettve operation. The Licensee concluded that 102.55 was the exact power level and operating at that power level did not i invetidote any of the UfsAR Chapter MV conclusions.
e Work Control Problems: During the Unit 2 refusting outage, the licensee and the NaC Identified additionet emanples of failure to follow established procedsres relative to the control of maintenance work activittee. These examples were simiter to those previously l Identified daring the Unit 1 outage, November - December 1993. i i

The nucteer businese mit will encompass att operationet and stoport activities for both seten units and Nope Creek. Since October senior management has etso appointed a new salem general annager and a new quality assurance end nucteer safety review manager; they have replaced the station quality assurance manager, the mechanical meintenance manager, and the 1 planning manager. As discussed above senior PSEM management met with Region I senior l management on March 12, to present a preposed Setem reorgenf ration. The new orpentration would add a mit i director and a unit 2 director reporting directly to the Sales general manager. The new organization would also add (for each unit): a mit operations manager, unit senior nuclear shif t supervisor, unit maintenance annager, mit planning manager, and '
mit outage planning manager. Sales management has taken steps to increase the emphasis on l acco mtability from the Vice President of operations down through ett levels of management i to the workers.

- MAINTENANCE /9URVEILLANCE The board concluded that performance weaknesses were evident in meintenance programo and activities, such as procedurst meerence and adequacy, the feecheck process, specification of post maintenance !
testing requiremente, and control of work activities by numerous onelte groupe. Management has fsproved its safety focus in prioritising and schedJLine maintenance activities. However, management oversight of corrective action program activities has been weak me evidenced by the high recurrent egalpment failure rates. Inconsistencies in troubleshooting activities and root cause anstysis ,
contributed to the deley in correcting recurring problems. Meterial conditfon of the plant continues to improve, but there remain severet areas that need improvement. Although the in service testing program was adequate, management did not effectively resolve self essessment findings. Programs for ,

- 2. LICENSEE RESPONSE TO PREVIOUS SALP FUNCTIONAL AREA WJ4NESSES/RECENT LICENSEE PERFORMANCE TREles (in the test year) l 8 OPERATIONS l t
The Licensee response to the SALP did not provide detailed information on plans to address performance inadewacles. The response ponerstly agreed with the NRC's assessment of Sales performance, in eMition, the response stated an intention to correct Selen performance problems. Since the response i letter wee issued, senior PSEM management hee initiated an effort to determine the cause of the !
ineffectiveness of previous corrective actlant. In seltion, PSEM management proposed reorganf rations of several organizations (discussed in more detall below), and loplementation of a ' step change' process intended to produce results, rather than activity without results.
4 The proposed re-orgenlaation would quickly bring the mitization concept to fruition for Sales l Operations. Two plant directors (one for each unit) would report to the Salem Generet Manager. In turn, two operations managers (one for each unit) would report to the directors, and each operations i manager woutd have responsIbllity for a unit operations depertaant, Inc1udIne a Senior NucIeer Shift S w ervisor and the ehlft complement necessary to sg port operation of that unit. It is fsportant to
! note that, as of March 15, the Licensee had not reached a finst conclusion to leptement the propose orgenlaation.
In response to the April 7 ovent, operations management provided leprowed ouldance to operotors for command and control and conservettve operation of the plant.
In response to WRC concerne, Operations management developed a flow chart for operability determinettone. Inspectors have occasionally noted weak or incorrect interpretation of Technical Specifications.
The inspectors have also noted that the Operations Manager has convinced the department staff that change is necessary, and fostered an increasing sense of ownership and team work.
e MAINTENANCE AND SURVEILLANCE Secondary /goP ewfpeont deflciencies pose significant challenges to plant operations, e.g. menway fallure, condensate header danese, COPU filter replacement, CW travelling screens, FW feed control at low power tevole.
In order to leprove overalt performance and response to emergent issues, PSEM reorganized the
- Melntenance Department. Changes included replacing the single Melntenance Manager role with three new positions
- 1) Mechanicet Maintenance Manager, 2) Controls Maintenance Meneger, and 3) Planning Manager. PSE M began to mittae these departments. The proposed (as of March 15) reorganization would further unitize maintenance planning management structures. As of March 15, mit 1 and unit 2 had separate outage planning managers. The proposed reorgenlaation would provide seperate (non-outage) planning managers and maintenance managers for each mit, reporting to the unit directors for their respective mits. The a

- mit maintenance annagers would oversee mechanical, electricet and l&C maintenance for their respective mits (recombining the disciplines under one maintenance manager for each mit).
To address the existence of Long standlns equipment problems, plant management required operators to l develop a list of workarom de to be addressed by maintenance personnel in accordance with assigned i I
priority.
l
.
- ENGINEERING AND TECHNICAL SUPPORT j Sales and corporate engineering have not consistently consemicated well with operations, nor has
[
i operations caemmicated well with engineering. System engineering has not effectively prioritized i
- their workload, nor have they effectively monitored agalpment reliability, as demonstrated by the !
"workeromer' IIst generated in response to this NaC Identified concern. The system engineers did not I receive training on operability or Generic Letter 91 18 mtfl September 1994.
An NRC observation related to the Selen rod control Issue was that the inittel troubleshooting efforts locked clear leadership and delegetlen of responsibilities. This resulted in the efforts narrowly focusing on the most recent system entfmetion without adequate attention to the repetitive nature of 4
the feltures and the need to deteralne and correct the root cause. The fatture of PSE&G to determine I the root cause of the failures resulted in n eerous aborted start @ ettempts. The team did observe significant leprovements in the control of trosteshooting and root cause determinetton daring the inspection. A management oversight team was initleted to review ett !&C troubleshooting activities in en of fort to redace events caused by trosleshooting.
l In late February 1995, PSE&G announced a reorganization of the Nuclear Engineering department (corporate engineering). PSE&G management redirected resources no longer regJfred to s g port the Salem revitalization project (since it would be substantially complete in 1995) to better support $ stem and ;
.' Nope Creek operation. The effects of this reorgenlzetion have not yet been demonstrated.
4 In addition, Selen management rotated the Technical Sgport manager to the euellty Assurance and Nucteer Safety Review department to provided leproved oversight of euclity Assurance and corrective ;
action programs. Selen management had not named a permanent replacement Technical Sg port manager as of March 15. I e PLANT SUPPORT The NRC noted that PSE&G continued to perform at a noteworthy levet in the eres of radiological protection through the end of 1994, especlotly during the recent unit 2 refueling outage.
The Licensee's annual portf et.perticipation emergency preparodiess exercise was condacted on Jee 23, 1993. On-site response to the sleuteted emergency was very good. An exercise strength wee Emergency Response Manecer command and control. No eneacise weeknesses were identified. Significant erees for potentiel leprovement were maintenance team tracking from the operational Support Center and public address system operability in the Technicet Sgport Center.
The PSE&G security program continues to be effectively directed towards public health and safety.
However, certeln essessment elds have deteriorated to the point there maintenance was no longer effective.
e SAFETY ASSESSMENT /ouALITY VERIFICATION In July 1993, the lfconsee formed a Comprehensive Performance Assessment team (CPAT) editch conducted a special assessment of safety issues and recent plant events using en integrated MORT investigatory enelysis. The CPAT developed comprehensive root causes for these events, and the licensee has formed task teams charged with developing corrective actions. PSE&G has held periodic meetings with the NRC to discuss CPAT findings, and the NRC continues to monitor licensee progress in this eree.

engineers and the former General Manager (QM), Operations Manager (OM), and, to a lesser extent, the Manager oustity Assurance & Nucteer Safety Revlow (QA&NSR). 01 e 4stantleted heresament and j Intimidstlen (N&l) in thle case. Enforcement conferences were concheted with the licensee and the i effected managers on February 8 5 23, 1995. Some of these managers engaged in willful eleconchet (pre-decisional). Enforcement action is pending.
l Since the licensee's effort to terminate several esployees for poor performance on July 18, 1994, the Region hos received additional euttifaceted attegettone from two terminated employees that are currently mder review. One of these pertelned to 23 separate management, operations, and engineering concerns. These were presented to NRC personnel in a fece to face meetirg on August 8,1994. One
- concern pertelning to the low pressure over protection system (POPS) was s entantiated. Inadequate design compromised the redundant capability of the PORVs to limit RCS pressure mder low toeperature conditions. An enforcement panel agreed to proceed with additionet action after 01 completed its review of potential ulltful misconchet and herseement and intimidation issues. An additional multifaceted ellegetton involved both technical fasues and potential M&I lasues. This allegation concerns ela technical issues relsed regarding the environenntel quellfication of equipment.

- wrongdoing issues are being reviewed by 01. This allegation also involved a terminated enployee. The )
j NRC received this allegation from senior PSE&G management.
Additional ellesettons with potential safety significance have been sthstantiated. Non safety related l limit switches were Installed in two of eight reactor vessel heed vent velves (safety related I e application), and an incorrect Technicet Speelfleetion definition of controlled leakage, with the result that Safety injection flow supptled to the core, in the event of a RCP seal supply line failure during an accident, could have (and at times would have) been less than assumed in the accident snelvels (no violation was issued, since Salem wee always in compliance with the Technical Specification rewirements).
Cottoctively, these ellegations lepticate the previous station management's ability to personally resolve and address safety issues. Regarding the December 1992 altercation, this incident and the two 1
related ellegations appear to be chse to management's confrontational attitude with QA&NSR personnel. j i Since these managers have been replaced, thle concern appears to have dissipeted. The E0 ellegetlen and its 01 cogenent, and the 8/96 allegation appear to stem from a tendency of PSE&G to manage try meno. They are not effectively using their root cause programs. Management's failure to identify and !
i resolve root causes was a direct contributor to these two allegations. Based on the SALP (50 272/93-
- 99) and a recent engineering inspection (50 272/95-01), this appears to be a continuing concern.

SALEM EXECUTIVE SLsetARY LICENSEE PERFORMANCE STRENGTMS AND WEAKNESSES Salem performance continues to be inconalstent.
1 e Capacity factor has been low dJe to refusting outages et both units and numerous forced outages and power reductions resulting from problems with SPPS, MS-10s, pressurfter code safety valves, rod control, and to sg port PORV replacement es well as e@lpment modifications following the April 7 event. Grass fouling of circulators and numerous plant trips contribute to the low capacity factor as well.
1 Strergths:
e The licensee continues to increase resources for a meterial condition improvement program. The NRC l
- has observed noticeable leprovement in the meterial condition of the plant, indicating that the d licensee has been earnest in the isplementation of leprovements.
- I e Radiation protection program laptementation continues to be very strong.
T
- When problems or conditions are self identified and self detected, event response and root cause determinetton are through and comprehensive, particularly when the metter is the adject of NRC 2
attention. In other cases, the licensee's performance is considered weeker, as identified below. .
1 e PSE&G has responded to identified performance and management weaknesses relative to approach to l problem resolution by initiating the following actions:
o PSE&G senior management has replaced the mechanical maintenance manager, the planning manager, the technical so port manager, and the Salem QA manager'with personnel from within the r$E&G orgenlaation; and hos filled the General Manager position and the Quality Assurance and Nuclear Safety Review position with new personnet from outside the company.
e Verifying the effectiveness of numerous swervisors and managers and changing the incudient when deemed appropriate.
e Pursuing mititetton of the operations organization; maintenance and plaming organizations are 1 mitized. Additionet changes have been proposed to further unitiae operations, plaming, and maintenance managers below the proposed plant directors. i
, e Implementing the enleting performance assessment tools to (grove accomtability from the highest levels of management down to rank and file workers.
e Forming dedicated teams to laplement the corrective actions developed in response to the CPAT l findings.
e Initiating a team of consultants and senior managers from other utilities to determine the cause of the ineffectiveness of PSE&G corrective actions for Salem to date.
$ e Developing a ' step change' process intended to hold managers accountable for achieving measured performance isprovementa.
Weeknesses:
Selen performance has been week in:
e Planning.
Salem m necessarily rendered an entire train of Service Water inoperable for a valve repefr that didn't need i s be done, and didn't get completed. Sales planned maintenance on an EDG to tros le shoot a non safety portion of the test controls, without determining if parts were evallable; this extended the time in the LCO.
\
e Control of maintenance.
Level III violation in the Unit 2 outage for lack of procedure eserence and lack of tagging control. Mechanics changed the olt in the wrong component in the AFW pump, and mintentionally
" adjusted" the overspeed trip test device. The Selen Unit 2 PORVs were replaced with the "wronga internata (not the parts intended). The correct internets were esse @ently installed daring the recent Unit 2 outage.
- e Engineering and Technical Sgport.
System engineering has poorly trended equipment reliability (for example, the Diesel air start system, the control air system). Engir. sering (corporate and system) has not casemanicated well with operations (for the most part, the operators don't know who they are). System engineering has not been involved in operability deciolons, and was not trained on operability (Generic Letter 91 18)
4 l
. 2 totll I made a big issue out' of it.
j e secognitlon of the need to do root cause determinetton.
e corrective action effectiveness due to inedequate root cause essessment.
- e inadequate approach to problem resolution (i.e., general tendency to fin problems or conditions based on the most probable cause without essessment or understanding of all possible causal factors.
a Examples include, but are not limited to the licensee's initlet response to cracked diesel liner
+ leeues, failure to identify elevated reactor power in 1992, and f alture to recognize generic l laptication of rod control problems.)
GENERAL OgSERVATIONS: i l
j orpenlaation may not have sufficient level of knowledge relative to managing change based on observations by 1
DAP and DR$ inspectors.
I i Until recently, the salen organization never engaged in attegting to benchmark itself rotative to other I utilities, including Hope creek.
1 1 New emphasis on accountability, ownership of problems.
j The July 1994 termination of 50 60 personnet appears to have been well received (by those who were not terminated). Generally positive comments from remaining staff acknowledging that there were several week performers that felled to contribute to overall gelity or safety.
l While J. Megan has been pushing for more swervisory field time, increased first line s wervisory presence I le not very apparent. However, there is a noticeable increase in the presence of middle management level )
personnet. i There are several examples recurring problems In pop (service air, and fee & ster) and some safety related l systems (EDG air start) have the potentist to effect nuclear plant performance.
It is not clear, that the maintenance orpentzetion and system engineering organizations understand and
, appreciate the need to change. Unable to agree on meaningfut leprovement strategy teless leposed from the j top down. Passive attitude seems to exist relative to chenho. Taken g with day to day crisis management.
still tend to focus on most inmediate proximate causes associated with an event.
White management is driving change, noticeable improvement in plant performance and personnet attitude and enthusteam for determining and laptementing improvement strategies and plans is not yet apparent.

II. PLANT PERFORMANCE DATA
- 1. CURRENT OPERATING STATUS (for period 10/1/93 to 3/1/94)
PSE&G shut down Unit i en October 1,1993, to commence a 72 day refueling and maintenance outage. Prior to the shutdown, the unit had been on line since July 15,1993, and operating at or near full power. Plant management extended the outage completion date (originally scheduled for December 17) because of emergency diesel generator (EDG) operability concerns. On December 2,1993, a cracked cylinder liner in a Unit 2 EDG raised generic operability concerns for Unit 1 No. IB EDG because of the similar liners installed in No. IB. Operators restarted the unit on January 24; it automatically tripped from 100% power, on January 27 in response to a low <
water level condition in No.14 steam generator. Operators restarted the unit on January 31, and operated the unit at power until it automatically tripped, from 100% power, in response to a loss of control power to the main turbine control system. PSE&G rewarted the unit February 13, synchronized to the grid February 20, and has operated the unit at or near power through the end of the month. ,
PSE&G operated Unit 2 at or near full power throughout the fall, until December 3,1993, when operators shut down the unit due to failure of a cylinder liner in the 2C EDG. After completion of repairs to the EDG, operators restarted the unit on January 3,1994, and operated at full power until January 19, when the reactor engineering staff discovered that PSE&G had apparently operated Unit 2 in excess of 3411 megawatts (thermal). Since then, and through February, operators have maintained Unit 2 at 95% power.
- 2. RECENT SIGNIFICANT OPERATING EVENTS AND IDENTIFIED SAFETY CONCERNS I
- a. Sienificant Events (oflast 12 months) l
- Unit I automatically tripped on February 10,1994, from 99% power, in l response to a loss of 15 VDC power to the main turbine control system. The l plant stabilized at normal operating pressure and temperature. PSE&G l determined that the 15 VDC power supplies had tripped when their protective l relays sensul an over-voltage condition. (See IR 50-272/94-01)
I l l
- Unit 1 automatically tripped on January 27,1994, from 10% power, in '
l response to a low water level condition in No.14 steam generator. The cause l of the trip was a level error controller in the control circuit for No.14 steam l generator feedwater regulating valve, which caused generator water level l control to malfunction in the tuto position. This malfunction generated the l low water level condition and subsequent reactor trip. (See IR 50-272/94-01)
Salem PSR Page 5
l
- Operators shut down Unit 2 on December 3,1993, from 100% power, due to j failure of a cylinder liner in 2C emergency diesel generator (EDG). PSE&G l conservatively determined they had a basis for concern about the particular l liner's reliability and consequently declared Unit 1 EDG IB inoperable as
. l well, since the IB diesel had similar liners installed. (See IR 50-311/93-27) l l
- On November 2,1993, operators declared an Unusual Event (UE) in response l to a fire in a 230 volt lighting transformer in the Unit 2 turbine building. The l fire brigade responded to the scene and extinguished the fire. The station was ;
~
, l in the UE for approximately one hour. A loose electrical connection caused l the fire. No personnel were injured and no safety-related equipment was l affected. (See IR 50-311/93-23) l
< l
- On October 13,1993, operators declared an UE in response to a fire in the
, l Unit i No.12 service water piping penetration bay. The shift supervisor l notified PSE&G Fire Department, which responded to the scene and l extinguished the fire. The station was in the UE for about 50 minutes. The l fire was caused by sparks from a grinding activity, which ignited insulation l from service water piping. Three contractor employees were treated for
, l smoke inhalation; no equipment sustained damage. (See IR 50-272/93-21) l 4
l
- On August 24,1993, operators initiated a Technical Specification-required shutdown of Unit 1 in response to a degraded voltage on a cell in the IC 125 l
l '
l volt battery. The need to shut down was relieved when the NRC exercised l enforcement discretion in response to the licensee's request and associated i l justification. (See IR 50-272/93-20) l
,. 1 i
l
- On July 11,1993, while the repairs to a faulty Unit I feedwater isolation j protection relay were being performed, the main feedwater regulating valve for l the No.14 steam generator inadvertently went closed at 8:38 p.m., resulting i l in the water level in that steam generator dropping to a level sufficient to l cause an automatic reactor trip. The licensee determined that the technician l l who was repairing the SSPS relay lifted an improper lead and caused the l l isolation of the No.14 steam generator. The licensee additionally determined 1 l the root cause of the technician's error was inadequate detail and direction in l the SSPS troubleshooting plan. Subsequent to the cause determination of the l trip, PSE&G repaired the SSPS and commenced a reactor startup on July 15, l 1993. The unit was returned to service on July 16,1993. (See IR 50-l 272/93-19) i I
l
- On July 10,1993, toxic gas release (ammonia) in the Unit I turbine building l caused by a loop seal failure on the ammonia hydroxide storage tank due to l l overpressure. This apparently resulted from excessive ambient temperature )
l conditions. The licensee will change the concentration of the ammonia l hydroxide in the tank to increase the boiling point of the solution to prevent j
~
l recurrence. (See IR 50-272/93-19) l l
- On June 8,1993, Unit I automatically tripped following massive intrusion of Salem PSR Page 6
.~ l sea-grass into the circulating water system suction. Four of five operating
- l. circulating water pumps tripped, causing a loss of main condenser vacuum, l turbine trip, and subsequent reactor trip. (See IR 50-272/93-19) :
l I
l e On May 28,1993, Unit 2 was manually tripped by the operators per abnormal !
l operating procedures when control bank "C", group I control rods (four rods [
l total) fell into the core during reactor start up operations. At the time the i l operators were diluting the RCS to criticality for post-refueling startup. A l i
l card failure was attributed to a degraded solder trace in the rod control system, l which led to the event. (See IR 50-311/93-81) ;
i I
l e On March 16,1993, Unit 2 automatically tripped from 100% power due to a >
l low-low level condition on the No. 24 steam generator. A failed pressure l l control switch in the condensate polishing system led to a low suction pressure j l condition for the No. 22 steam generator feed pump and subsequent feed pump t trip, which caused the steam generator low level reactor trip. (See IR 50- ;
l 311/93-08) ;
l I
- b. Performance Indicator Data Units 1 and Unit 2:
o Performance indicators generally show good performance. Capacity factor ,
numbers were low for 1993 due to back-to-back outages of Unit I and Unit 2 i and shutdowns for potentially generic safety issues such as rod control and !
diesel generator cylinder liners. No other significant trends are evident in the statistical analysis.

l c. Recently Identified Technical Safety and Managerial Challennes l i
l (oflast 12 months)
I l
- Four resident inspectors are permanently assigned to Artificial Island (Salem l and Hope Creek).
I l e The NRC Resident Office continues to monitor and evaluate the licensee's l
l efforts to improve plant material condition, repair and replace service water l piping, upgrade the RMS system, complete actions relative to Appendix R )
l requirements, issues associated with fire watches and security guards, !
l personnel error reduction efforts, and procedure quality and compliance l improvement efforts. i l
J e Reviews were conducted and are planned for erosion / corrosion program. ;
I l e Service Water (SW) 12aks: Numerous SW through wall leaks continue to j l occur due to erosion and microbiologic induced corrosion attack of carbon ,
steel piping. The licensee has a seven year pipe replacement project that will I l
l replace 95% (about 19,000 linear feet are safety related) of the safety related ,
l Salem PSR Page 7 l
1 i
- l SW piping with 6% moly stainless steel. This project will continue through ,
- 1 1995 (two more refueling outages per unit). Currently, approximately 90% of ,
j -l the safety related portion of the project has been completed, including the t
- i pipe replacement project is progressing satisfactorily as scheduled. {
! l
. l
- Radiation Monitoring System (RMS) Problems: RMS problems have resulted l: l in numerous ESF actuations and reportable events. Short term corrective
- l actions were completed on both Unit 2 and Unit I during the 1992 refueling
] l outages. These changes include electronic upgrades and a new uninterruptible l
! l I power supply. Longer term actions (1993-4) include a complete system ;
j ! upgrade. Based on NRC inspection, the upgraded RMS operation to date has j l been satisfactory.
i I l j l
- Failure of Overhead Annunciators: On December 13,1992, a Unit 2 operator >
i l
discovered that the overhead annunciators had not been updating alarms for l
I about i 1/2 hours. This was the result of a member of the operating shift -
-l entering a keystroke combination into a remote control workstation that, when !
. I input through the wrong system port, prevented the system from updating :
l alarms. An AIT was dispatched to the site and concluded: (1) the root cause l
I j l was a failure to follow procedure for proper operation of the overhead i l annunciator system; (2) the design of the OHA system permitted the operator '
j l to inadvertently emulate the password-protected software without warning.
I
- l
- Rod Control System: On May 27,1993 Unit 2 operators experienced several i l problems with the rod control system. The most significant event was that i l during an attempt to insert Shutdown Bank "A", one control rod actually 3
l withdrew 15 steps'of travel. An AIT was dispatched to the site and j l concluded: (1) the root cause was an introduction of static charges into the ,
l solid state electronic components which caused system damage; (2) damage
! l. was also caused by voltage spikes originating from "back EMF" in the I system's electro-mechanical step counters (the suppression diode installed to l mitigate this previously-known phenomenon was disabled due to a failed pin ,
connector on the affected circuit card). !
i l I
l At 5:12 p.m. on July 18,1993, Salem Unit 2 Control Bank D (8 control rods) l l began stepping inward at a rate of 72 steps per minute, but only moved a few j l steps before being detected by operators. At the time, Unit 2 was at 100%
- i l power with the control rods in automatic. The operator, finding no apparent
, l cause for the rod insertion, positioned the rods in manual control, which l I stopped the rod movement. The operators performed all actions per their '
l l l abnormal rod movement procedure (AB-ROD-0003) and were still unable to
] l positively identify the cause. The licensee installed monitoring instrumentation g l on the inputs to the automatic rod control signal summator and at 11:40 p.m.
8 l on July 18, returned rod control to automatic. l l l l At i1:24 a.m. on July 21,1993, the. licensee again experienced the same l phenomenon on Unit 2. As in the previous occurrence, the operator quickly 1 4 Salem PSR Page 8 1
4
, - - - - . - *~- , . - - - - _ _ _ _ _ _ . _ _ _ _ _ _ _ - _
l evaluated the situation and appropriately placed the rods in manual control. In l both cases the rods only moved inward a few steps (2 and 4 steps
] respectively). Current traces on the signal summator input revealed no change l from the nuclear instrument (NI) or turbine impulse pressure, but some spiking l from the average temperature (Tave) and reference temperature (T ref) input.
l Together these four signals are the input signals to the automatic rod control l system. On July 21, the licensee placed additional monitoring instrumentation l on the output of the signal summator, output of the " rod in output" signal l comparator, and individually on all four Tave channels.
l l On July 22,1993, during I&C troubleshooting, the licensee was able to I identify a fault in the signal summator, which erroneously produced a high rod I inward demand output for a relatively small temperature error input.
l l e Switchyard Modifications: During the recent outage on Unit 1, PSE&G l implemented an extensive design change package involving modifications to l the Salem switchyard. These modifications increased voltage recovery on vital l and group buses during bus transfers, provided load growth capacity, removed l the Salem circulating water system pump motor feeds from the Hope Creek l switchyard, improved voltages in both Salem plants, provided margin for short l circuit capability, and improved plant reliability. Major components added l included two 500/13.8 kv transformers, four 13.8/4.16 kv transformers, four l 13.8 kv breakers, and 4.16 kv switchgear for the circulating water system bus.
I l
- Unit 2 Sustained Operation of Greater Than 100% Power: Suspected root -
l cause is erosion of the feedwater flow nozzles resulting in i- wect online I calorimetric data. Upon discovery, licensee immediately r.J wd power for l both units, and began adjusting instrument setpoints to insure conservative l operation. Licensee is pursuing determination of the exact power level and the l effects on the UFSAR Chapter XV analyses. They expect resolution by mid-l April 1994.
l l
- Emergency Diesel Generator Cylinder Liner: This caused Salem 2 to shut l down as a result of a cracked liner, and delayed Salem 1 to delay startup from I the refueling outage. The licensee could not find a clear root cause. The l suspected root cause was dimensional tolerance problems with liners l distributed by Canadian Allied Diesels. PSE&G determined that only two l liners have ever failed, including the Salem liner, in a population of tens of l thousands of liners in use world wide (including locomotives and ships).
- 3. ESCALATED ENFORCEMENT ACTIVITIES
- The NRC issued a Level III Violation on March 8,1994, documented in NRC Inspection Report 50-272 and 311/93-23; 50-354/93-25. The violation was based on multiple examples of PSE&G's failure to follow procedures and their failure to properly control safety-related activities.

- b. SALP Overview (derived from the summary caragraoh of each SALP sectionh OPERATIONS On July 29,1993, the SALP board met to discuss PSE&G's performance at Salem during the period from December 29,1991 to June 19, 1993. The board concluded that the licensee had operated the Salem units safely and that operator response to operational events was excellent. The overall performance in the Operations area was good.
However, weaknesses were noted in the decisions to restart Unit 2 following the rod control system problems, in the failure to follow procedures resulting in the loss of Unit 2 annunciators, and in the inadequate oversight of the fire protection program.
4 Salem PSR Page 11
. MAINTENANCE / SURVEILLANCE The board concluded that the Salem maintenance and surveillance programs contributed i to the safe operation of the two units during the assessment period. In general, a !
declining number of personnel errors in both maintenance and surveillance indicated i improving performance. However, the number of transients induced by con'ponent i i
failures and the significant problems with the rod control system raise quest'ons regarding the overall effectiveness of the maintenance and engineering support functirms.
1 RADIOLOGICAL CONTROLS 1
PSE&G continued to implement effective radiological controls and ALARA programs during this period. The SALP board noted improvements in this functional area ;
including strong management support and oversight. Quality Assurance audits in this area were of very good quality.
EMERGENCY PREPAREDNESS l The SALP board determined that PSE&G maintained a generally strong and effective ;
emergency preparedness (EP) program. However, the board was concerned with an I apparent decline in the ability of the licensee to make correct initial Protective Action Recommendations during training, drills and annual exercises. This concern resulted in j the board's assessment of a declining trend for this area. The board also concluded that i i
PSE&G continued to maintain an effective and performance-oriented security program during this period. Overall, licensee perfonnance in both EP and security remained j excellent. i 4
l ENGINEERING AND TECHNICAL SUPPORT l Engineering and technical support organizations provided good support for refueling and
- maintenance outages, and strong performance in addressing day-to-day problems. The
! SALP board noted that training programs for engineering personnel were excellent but that weaknesses were observed in the licensee's non-conformance, erosion / corrosion, and i fire protection programs. Although the root cause training program was viewed as a i strength, the board noted that the threshold for initiating actual root cause investigation l was not clear or consistent.
- PSE&G management continued to provide generally effective management support.
l Significant Event Response Team (SERT) reviews of major events have been effective.
However, the board noted that in several instances, PSE&G failed to initiate adequate root cause evaluation or assessment of abnormal conditions. NRC interaction with PSE&G management was needed in a number of cases in order for full evaluation and
- corrective action to be taken in a timely manner. Once initiated, comprehensive
- assessment, root cause analysis and effective corrective actions were implemented.
Outage planning and training programs in all areas were considered strengths.

- 2. LICENSEE RESPONSE TO PREVIOUS SALP FUNCTIONAL AREA WEAKNESSES / RECENT LICENSEE PERFORMANCE TRENDS (in the last year) l l l
- OPERATIONS I
l PSE&G continues to safely operate the units. Operator plant knowledge and response to l events remains strong, however, operator response has been less than thorough regarding l indications of stuck-open RHR check valves, indications of a possible leaking RHR l pressure isolation valve, and a case of indeterminate hotwell level.
I I Recent management changes included the naming of a new Operations Manager in l September 1993, and two new Operations Engineers in January 1994. The licensee
, l intends to pursue full unitization of the Salem operating crew shifts.
l I
l
- MAINTENANCE AND SURVEILLANCE l
l Although maintenance and surveillance activities remain generally good, as exhibited by l strong Maintenance Department performance in response to the December 1993 EDG l cracked cylinder liner issue, the recent Unit I refueling outage was marked by multiple l examples of poor work control practices and multiple examples of failure to follow l procedures.
I l In order to improve overall per'iormance and response to emergent issues, PSE&G has l reorganized the Maintenance Department. Recent changes include replacing the single l Maintenance Manager role widi three new positions: 1) Mechanical Maintenance
- l Manager, 2) Controls Maintenance Manager, and 3) Planning Manager. PSE&G is also l pursuing unitization in these departments.
l
- l l
- ENGINEERING AND TECHNICAL SUPPORT I
l l Both Salem system engineering and PSE&G nuclear engineering have continued to l provide good engineering support for plant operations.
l l An NRC observation related to the Salem rod control issue was that the initial l troubleshooting efforts lacked clear leadership and delegation of responsibilities. This
] resulted in the efforts narrowly focusing on the most recent system malfunction without l adequate attention to the repetitive nature of the failures and the need to determine and l correct the root cause. The failure of PSE&G to determine the root cause of the failures l resulted in numerous aborted startup attempts. The team did observe significant l improvements in the control of troubleshooting and root cause determination during the l inspection.
I Salem PER Page 13
l e PLANT SUPPORT I
l The NRC noted that PSE&G continued to perform at a noteworthy level in the area of l radiological protection through the end of 1993, especially during the recent Unit 1 l refueling outage.
I l The licensee's annual partial-participation emergency preparedness exerc.c was l' conducted on June 23,1993. On-site response to the simulated emergency vs very l good. An exercise strength was Emergency Response Manager command and control.
l No exercise weaknesses were identified. Significant areas for potential improvement l were maintenance team tracking from the Operational Support Center and public address l system operability in the Technical Support Center.
l
- l The PSE&G security program continues to be effectively directed towards public health l and safety. A strike by the security force was narrowly averted when a new labor I agreement was reached in November 1993.
I I
l e SAFETY ASSESSMENT / QUALITY VERIFICATION I
l In July 1993, the licensee formed a Comprehensive Performance Assessment team j l (CPAT) which conducted a special assessment of safety issues and recent plant events l using an integrated MORT investigatory analysis. The CPAT developed comprehensive l root causes for these events, and the licensee has formed task teams charged with l developing corrective actions. PSE&G has held periodic meetings with the NRC to l discuss CPAT findings, and the NRC continues to monitor licensee progress in this area.
l l In February 1994, PSE&G Vice President of Nuclear Operation (VP-NO) assumed the l collateral role of General Manager of Salem Operations. The licensee also initiated other l management changes under the VP-NO and intends to pursue unitization of the Salem l units. PSE&G has implemented these changes in order to achieve sustained improvement l in the area of Salem performance.
I i 3. LICENSEE PERFORMANCE STRENGTHS AND WEAKNESSES
- Salem performance continues to be inconsistent.
- e Capacity factor has been low due to refueling outages at both units and forced outages i due to rod control problems, and diesel liner concerns.
Strengths:
The NRC has documented progress or good performance in:
i e Material condition e Procedure quality Salem PSR Page 14
. o Radiation protection program o Event response and root cause determination when the need to respond or evaluate has been identined Weaknesses:
Salem performance has been weak in:
o Control of maintenance e Recognition of the need to due root cause determination, e Inspectors have observed a production oriented mindset e Examples include imlial response to the cracked diesel liner, failure to identify elevated reactor power in 1992, failure to recognize generic implication of rod control problems e Management performance (tolerance of above conditions).
e Licensee Response Actions For Identified Concerns:
o PSE&G has responded to identified performance and management problems by:
e Replacing the Salem General Manager, on an interim basis (approximately one year) with the Vice President, Nuclear Operations.;
e Rotating the majority of managers reporting directly to the Salem General Manager, o Pursuing unitization of the maintenance, operations, and planning organizations, e Implementing the existing performance assessment tools to improve accountability from the highest levels of management down to rank and file workers, o Forming dedicated teams to implement the corrective actions developed in response j to the CPAT findings.
! e The licensee continues to increase resources for a material condition improvement program. The NRC has observed noticeable improvement in the material condition of the plant, indicating that the licensee has been earnest in the implementation of
- improvements.
i
- The Procedure Upgrade Project (PUP) was closed out in September 1993. A large l- majority of procedures were reviewed and upgraded, and procedure maintenance has
! been made the responsibility of the Technical Department.
t l e A meeting was held on July 9,1992, to discuss concerns associated with the Fire Salem PSR Page 15 i

l
- Protection Program and the status of Appendix R open issues. In a letter dated September 15, 1992, the licensee stated that they had completed Appendix R modifications and the penetration seal project. Further, the fire damper project is !
scheduled for completion in 1995. An Appendix R inspection was conducted in May :
and July 1993. NRC identified concerns with the licensee's qualification testing of 3M fire wrap material. !
- A management meeting was held on July 16,1993, to discuss a new comprehensive self assessment of licensee activities associated with a number of recent performance issues at the site. The licensee intends to review a number of recent events utilizing a MORT-type investigation process to discover possible root causes that may have been missed previously. This effort is expected to be completed by December 1993.
- 4. NRC TEAM INSPECTIONS WITIIIN THE LAST YEAR Area /Date Findings EDSFI Assessment Licensee-contracted EDSFI has been August 16 - completed. The NRC assessment of the September 3,1993 licensee EDSFI identified a number of minor concerns; but, concluded overall that the licensee's assessment was good.
Augmented Inspection Team (AIT) An AIT was formed to review and June 5 - July 2,1993 evaluate the circumstances surrounding a problem with the Unit 2 rod control system. The components within the control circuitry that led to rod withdrawal when operators were demanding rod insertion.
Appendix R Inspection Identified concerns with Kaowool and 3-M May 17-21,1993 fire wrap material. Also weaknesses in safe shutdown outside the control room and lighting. Re-evaluation to occur during July 1993.

Three allegations are related to harassment and intimidation of licensee personnel, up to and including allegations of promotion denial due to "whistleblowing." One of the allegations asserts that the Offsite Safety Review Group is not performing its function in accordance with technical specifications. OI is actively reviewing these cases.
Salem PSR Page 17
A fourth allegation asserted that the main security access center at the Salem / Hope Creek site was not manned as required by the NRC approved security plan. DRSS is scheduled to conduct a routine security inspection in March 1994 and will review this matter.
The fifth allegation concerns an operator wrongdoing issue. During and subsequent to the Overhead Annunciator (OHA) AIT in early 1993, neither of the two operators in the control room at the time of the incident admitted to any manipulation of the OHA system, even though clearly operator involvement was a contributor to the event. DRP is reviewing the licensee's investigation and followup into this matter and will determine this issue's resolution on the basis of that review.
The sixth allegation involves a technical question that suggests that HVAC ductwork integrity may not be assured under dynamic loading of new fast-acting curtain fire dampers. DRP is reviewing test procedures and results while DRS is scheduled to review the matter during the next routine fire protection inspection. >
i The seventh allegation regards evidence that the Rod Control problems experienced by the plant (and followed up by the AIT) occurred during stanup testing at the Zion nuclear station, even though Westinghouse representatives denied that the problem had ever .
t occurred before. OI has opened an investigation into this case and is currently reviewing the matter. ;
The final allegation concerns 6 technical issues raised regarding the environmental qualification of equipment. Upon agreement of the alleger, this matter will be referred to the licensee for resolution. Otherwise, DRS will followup it up.

I. OPERATIONAL PERFORMANCE A. Scram Summary Unit 1 7/14/94 - Operators manually tripped the reactor from 100% power in response to decreasing condenser vacuum caused by a lightning-induced loss of all circulating water (CW) pumps. The licensee determined that a design inadequacy (there was no time delay in the undervoltage (UV) pickup circuitry of the CW pump switchgear) resulted in unnecessary UV relay actuation following a lightning-induced voltage drop.
6/10/94 - Automatic reactor trip from 97% power following a main generator trip. The licensee determined that a transformer failed, causing the main generator output breakers to open resulting in a turbine trip and subsequent reactor trip. l i
Unit 2 l
- 9/29/94 - Operators manually tripped the reactor following an l operator inadvertently closing two main steam isolation valves while at 30% power.
6/29/94 - Automatic reactor trip on low-low steam generator water level during power. escalation. The licensee determined that
' feedwater recirculation valve cycling at low feedwater flow rates caused rapid changes in feedwater header pressure and steam generator feedwater flow. Subsequent investigation determined that improper gain settings caused unstable feedwater controller operation.
- Sianificant Operator Errors B.
On September 29, 1994, while increasing power on Unit 2, operators manually tripped the reactor from 30% power. A licensed operator, intending to close main steam line drain valves, inadvertently
- closed two main steam isolation valves (MSIVs). Operators manually tripped the reactor in anticipation of the automatic trip.
C. Procedures The licensee continues to experience problems with adherence to procedures and work practices. For example, the failure of a contractor electrician to adhere to stated work practices resulted in the individual cutting into the wrong 4160 Vac cable. The fact that the cable was de-energized at the time was fortuitous, since it was tagged out to support other work. Other examples of failure to adhere to stated work practices have recently been identified during I

There are at least two STAS per shift and they train with assigned operating shift crews. All STAS are required to have at least bachelor's degrees and hold senior reactor operator (SRO) licenses.
In normal operating conditions, one STA qualified individual is t typically assigned to the work control center, and the other l individual is assigned as an extra SRO to one of the control rooms i or performs as one of the two Nuclear Shift Supervisors. In an accident condition, the role of the STA is to assure that the proper I actions are taken relative to emergency response procedures, activities are initiated to mitigate core damage, and accident conditions are properly assessed and analyzed.

currently being reviewed by the staff. j
! For the safety injection system piping, PSE&G is developing a program that

i l V. STATUS OF THE PHYSICAL PLANT
} A. Problems Attributed to Acine I SERVICE WATER: Due to extensive corrosion and erosion of the carbon i steel service water piping, the licensee initiated a project to a
completely replace all service water piping (including the piping in i containment) with 6% moly-stainless steel in 1989. Currently, about j 95% of the service water system has been replaced. Completion of the service water upgrade project is expected by the end of 1995.
RADIATION MONITORING SYSTEM (RMS): RMS age and design has caused recurring system failures that have resulted in occasional ESF actuations or reportable events. Licensee budget constraints have
- prevented complete replacement of the system. However, the licensee has initiated short-term correctivo actions to make the system less vulnerable to certain failure modes. Improvements have been noted.
However, frequent RMS system failures and the associated

'. e l1 l'e j compensatory measures and corrective actions still require significant resources and attention from the operations and maintenance departments.
B. Other Hardware Issues j The licensee continues to experience recurring degraded system
< performance or conditions which require operational maneuvering to
- support unplanned maintenance activities. These conditions occur i i frequently and are often caused by material or design inadequacies. i
- Recent examples include:
CONTROL OIL POWER UNITS (COPU): Recurring filter differential pressure problems have required the licensee to frequently reduce l power to support COPU filter replacement. The cause of frequent
! filter loading is not yet fully understood by the licensee.
4 CONTROL AIR SYSTEM DEGRADATION: Recurring leaks and degradation of 1 the control air system are of sufficient magnitude that removing one
! air dryer from service for maintenance often has the potential to e adversely affect the performance of the entire air system.
i Compensatory measures are usually required to ensure satisfactory system operation.
i EMERGEACY DIESEL GENERATOR (EDG) STARTING AIR CHECK VALVES:
{
Moisture in the EDG air start system frequently cau es pipe i j corrosion. The licensee believes the build-up of corrosion prodccts is the cause of frequent check valve degradation associated with the i air receiver tanks in the air start system. Consequently, operators i frequently replace check valves, which requires that the affected !
EDG be declared inoperable while maintenance is in progress. j
- FEEDWATER SYSTEM CONTROLS: In November the licensee discovered an
! amplifier in the feedwater control circuitry, that was supposed to '
be set for a 1:1 gain, was actually set for an 8:1 gain. The condition is believed to have existed since initial startup.
' The
- amplifier affects low flow operations (power ascension, up to about ,
15%), an operating regime in which the licensee has historically
- experienced significant difficulty in controlling feed flow to the
Recent hardware issues: l i
On November 18, 1994, a main electrical disconnect in the 500 kV ;
c switchyard opened unexpectedly and for unknown reasons. The event I
- caused the isolation of the No. 4 Station Power Transformer (SPT-4),
- which affected the Unit I vital buses, and caused the loss of a train of three Circulating Water pumps.
i On November 22,1994, SPT-13 isolated due to degraded performance of l i
the transformer caused by current " tracking" on the outside of the j insulation due to an improperly installed boot seal and associated i potting compound which directly contacted the conductor. j 4
4 i
I t
On November 28, 1994, SPT-2 isolated for reasons unknown. The isolation affected the Unit I vital buses and resulted in loss of a train of three Circulating Water pumps. Since another Circulating Water pump was already out of service for maintenance, the operators had to initiate a rapid . power reduction to compensate for the reduced condenser efficiency and vacuum.
On November 28, 1994, the loss of a portion of the 13 kV ring bus i was caused by a fuse failure, and for unknown reasons, resulted in a loss of power to the Technical Support Center (TSC) and constituted a loss of accident assessment capability until power j could be restored.
The Salen Generating Station Units 1 and 2 are Westinghouse 4 loop !
PWRs with large dry containments. Station blackout had been identified in the Individual Plant Examination (IPE) to be a significant contributor to total Conditional Core Damage Frequency.
Each Unit is powered by three offsite power lines, and each Unit has three diesel generators. In addition, a gas turbine is located on site and is capable of providing emergency power to both units. In the event of a loss of offsite power, the required on-site emergency AC power is supplied by either 2 of 3 diesel generators, or by the gas turbine supplying power to the 13 kV system. The station blackout commitments have been implemented. These were to add a diesel-driven air compressor and battery room heaters, and to develop an EDG reliability program. The battery capacity meets the 4-hour coping period station blackout criteria.
A sensitivity study performed in the IPE found that the total core damage frequency (CDF) was increased by failure of the PORVs to open. During design basis transients, the PORVs are used to prevent challenges to the pressurizer safety valves and provide RCS overpressure protection. On 4/7/94, the PORVs performed successfully during a transient at Unit 1. Following this event, the Unit 1 PORV internals were replaced due to cracking noted in the valve stem related to IGSCC or hydrogen assisted cracking. The sensitivity study also found that the total CDF was sensitive to the probability of operator action failures under accident conditions.
l A factor of 10 increase in estimating operator action failure resulted in a seven-fold increase in the CDF. l l
l In 1994, the number of scrams while critical increased at Unit 1, but did not increase for Unit 2. Unit I experienced 4 scrams, while Unit 2 experienced I scram. This implies that the initiator
" Transient with PCS Available" frequency may be greater for Unit I
! than Unit 2.

C. Core Damaae Precursor Events 4
On the basis of the precursors identified by ORNL for 1992 and 1993 (NUREG/CR-4674, vols.17 through 20), the staff did not identify any precursor events for the site that have a conditional core damage probability of IE-5 per year or greater. j The following event was classified as a "Significant Event" by the Events Assessment Panel. On April 7,1994, the Unit I reactor j tripped from 25% power. The operators had reduced power due to the grass-induced loss of some CW pumps such that the RCS T-avg was too low. In order to increase the temperature, the operators pulled control rods. Subsequently, the reactor tripped on a Power Low Range /High Flux signal. The resultant transient caused the plant to go water-solid L High Head Safety Injection flow, and to rupture the PRT ble disc. The risk significant aspects of the event are primarily sne result of human errors of commission.
VII. ENFORCEMENT HISTORY 10/93 NOV WITHOUT A SEVERITY LEVEL - LOG FALSIFICATIONS - The action concerned the falsification of required fire watch records by a licensee contractor. The violation, which was i identified' by the licensee's contractor, involved 19 of 35 fire waten personnel falsifying logs to indicate that fire watch patrols were performed, when, in fact, the individuals had not entered the areas indicated on the logs. In accordance with the Commission's direction, an NOV with no severity level designation was issued.
3/94 CIVIL PENALTY - The action consisted of eight violations of failure to follow procedures related to the control of maintenance activities. While none of the violations were significant from a nuclear safety perspective, some demonstrated the potential to cause physical harm to
' individuals and collectively demonstrated weaknesses in the maintenance and control of work activities. ($50,000) 3 10/94 CIVIL PENALTY - The action was based on four violations ,

considered to be continuing violations, involving the failure 4 to identify and correct conditions adverse to quality including inadequate procedures and known equipment deficiencies. Both senior reactor operators failed to exercise command and control during the events. Each of the four violations was characterized as a Severity Level III violation. Enforcement Discretion was exercised by the staff
' to increase the proposed civil penalty to emphasize the need for the licensee to pror.ptly identify conditions adverse to i
. i quality and to implement effective corrective actions.

! steam generator water level initiated a feedwater isolation. The level j oscillations occurred when the minimum flow valve cycled open and closed. '
l The licensee changed procedures to improve operator control of the minimum flow valve. The licensee also changed the gain in the valve controls. '
j The operator reduced power to within the capacity of auxiliary feedwater; however, before water level could be stabilized in all generators, the No.
- 23 steam generator reached its low level setpoint causing the reactor trip. (See IR 50-311/94-14) e On June 10, 1994, while operating at 97% power, the Sales Unit I reactor automatically tripped following a main generator trip. The licensee concluded that a potential transformer failed, causing the main gener. tor output breakers to open, leading to the reactor to trip. The licensee sent the potential transformer to an outside facility to determine the cause of the component failure. (See IR 50-272/94-13) e On April 7,1994, the Unit 1 operating crew rapidly reduced power in !
response to severe river grass intrusion at the circulating water intake i structure. Salem Unit 1 tripped from 25% power during maneuvers to shut the plant down. Subsequent to the reactor trip, the plant experienced a series of safety injections which resulted in loss of the pressurizer steam bubble and normal pressure control. In addition to the reactor trip l and safety injections, certain valves that are required to operate, failed l to close. On April 8, the NRC dispatched an Augmented Inspection Team to !
the site to review the causes and safety implications of the multiple !
failures in safsty-related systems during the event and possible operator i errors. (See AIT Report 50-272/94-80 and 50-311/94-80)
- 2. ASSESSMENT Unanticipated equipment deficiencies continue to dominate performance of the Salem units. Although Sales unit I has continuously operated for more than 150 days, unit 1 operators had to reduce power six times in six weeks due to equipment problems from 11-6-94 to 12-17-94. On the other hand, the Salem units have experienced only one reactor trip in the six months beginning 8-1-94, as compared with five trips in the period from 2-1-94 to 8-1-94. Operators have begun to take significantly increased ownership for plant performance and safety.
Tt.eir involvement in insuring nuclear and personnel safety during the inspection of the no. 23 Reactor Coolant Pump seal illustrates their leadership in identifying and preventing pitfalls in plant activities. Maintenance management identified that lack of supervisory oversight of job briefings had resulted in ineffective worker preparation for maintenance activities. Steps have been taken to improve the job briefings. System engineering support for daily operations and maintenance activities continues to require significant improvement, while some improvement has been noted in design engineering support for daily activities.
Plant support organizations cont'aued to demonstrate excellence in their activities.
Overall, the number of challenges to uneventful Salem operations, although decreased over the last six months, continued at a high rate in comparison to other plants such as Hope Creek. Senior PSE&G management has implemented a number of changes intended to address the need for change, including replacing the Chief Nuclear Officer, the Sales General Manager, the mechanical maintenance manager, u
1 and the planning manager. Sales management has taken steps to incniase the emphasis on accountability from the Vice President of Operations down through all levels of management to the workers. Although some examples of improved performance have occurred, especially in the areas of operations and mairitenance, it cannot yet be determined whether PSE&G actions will result in lasting :hanges.

I. BASIS FOR CONCERN For several years the NRC has noted stagnate, and sometimes declining, performance relative to the licensee's (Public Service Electric and Gas-PSE&G) initiative and ability to successfully perform comprehensive and through root cause analysis of abnormal conditions or situations affecting the operation of the facility, or recognize trends that are indicative of programmatic weaknesses. Consequently, corrective actions have not always been effective, as evidenced by recurrent deficiencies of a similar nature or continuing performance weaknesses. The apparent exception to this general observation av matters that involved or required NRC attention, such as situations in which an Augmer. N Icsp etion Team was dispatched or other conditions that resulted in increased NRC attentbn. 4(.ordingly, when NRC is involved or demonstrates interest in a matter, the licensee generally responds with a comprehensive and thorough root cause assessment that forms the basis of a corrective action agenda. However, in an increasing number of other situations, the licensee's efforts appear to be directed to rapidly identifying a seemingly reasonabic cause, followed by the implementation of corrective actions which usually fail to successfully resolve the condition or situation. Consequently, recurrent deficiencies, problems, or weaknesses are continually identified.
Though NRC inspection, enforcement, and assessment activities have identified the same basic or similar weaknesses, to which the licensee has generally acknowledged and responded to with corrective action plans, PSE&G has never actually demonstrated significant performance improvement at Salem. In reviewing previous NRC activities (SALPs and inspections) since 1988, we have noted that the licensee's performance and our subsequent assessments have not significantly changed. The licensee continues to experience recurrent operational, design and maintenance-related problems with no indication that previously applied corrective measures have been effective in resolving or causing reduction in the frequency or severity of apparent problems.
The Summary of Significant Issues and Events at Salem. 1988-1994 Attachment 1 provides highlights of select events and NRC activities at Salem since 1988. While the events themselves appear generally unrelated, there is a remarkable similarity in the theme and causes for a majority of the items and problems observed in this period. Of particular note is the findings of an Maintenance Team inspection (April 1990) and an Integrated Performance Assessment Team (May 1990) relative to the identification of weaknesses involving management oversight and control, insufficient supervisory presence in the field, ineffective corrective action implementation, and inadequate maintenance pecen el control, insufficient oversight of contractors, inadequate root cause analysis and determination for some events, and procedural adherence.
Many of these same themes are recognized in subsequent events, including, but not limited to:
(1) the catastrophic failure of the Salem Unit 2 Main Turbine, November 1991 (AIT involved);
(2) the licensee's identification that at least half of the contract fire watches had falsified records or otherwise improperly conducted firewatch activities in the 1991-1992 time period (Special Enforcement Action; (3) the failure of the Salem Unit 2 Overhead Annunciator System to properly function due to the licensee's failure to understand system design and function, and improper operator action (AIT involved); (4) the control rod control system malfunction during 0
y four start-up attempts of Salem Unit 2 following an outage due to the licensee's failure to l
. understand system design, failure to properly assess root cause, and poor control of troubleshooting efforts (AIT involved); and (5) the Salem Unit I trip and subsequent plant !
stabilization problems that occurred on April 7,1994, as a result of suspected command and !
control deficiencies involving operating personnel. (AIT involved).
A management meeting 'was held with the licensee in July 1993 to discuss the licensee's difficulty in resolving problems and implementing effective corrective actions, in light of the !
three AITs conducted since 1991. In response, the licensee implemented an action plan. to perform a comprehensive assessment of their performance (CPAT), using several events l (including the AIT activities and recent plant trip events) as indicators of programmatic '
deficiencies. The CPAT effort was generally completed in January 1994, and identified causes having the same themes as previously identified by the NRC, and emphasized defects in the management and leadership of the Salem organization. Several problems were identified relative l to management skills and practices, work process control and worker performance, and problem i solving and follow-up. A management team has been assigned to determine, establish, and ;
implement corrective measures. The corrective action effort is still in progress. ;
Notwithstanding the CPAT effort, the licensee continued to experience several problems during the Salem Unit I refueling outage, which resulted in extending the outage from December 1993 l to February 1994. During the outage l NRC and the licensee identified several weaknesses and j violation of the established maintenance process and control program which had the potential to compromise worker safety. As' a result, the examples were the basis for an escalated i enforcement action and proposed $50,000 civil penalty issued February 10, 1994.
The licensee subsequently acknowledged the violations and submitted the penalty on April 8, 1994. In their response, the licensee identified the cause of these violations as less than adequate ;
supervisory methods (i.e., insufficient management and oversight), less than adequate verbal ;
communications, and less than adequate work practices (i.e., failure to follow procedures and !
failure self-check in accordance with established work practices), i.e., the same general causes l that have been continually noted by the NRC. While the licensee's stated corrective actions appear address the causal factors, given past performance, there is no assurance that~ the same i or similar events will not recur. 1 II.

i As a result of the CPAT effort and in recognition of continuing difficulties in effectively l i resolving problems, achieving performance expectations, the licensee has initiated efforts to l l restructure and unitize certain Salem organizational elements in an effort to accelerate j
- improvement in Salem Station performance. Accordingly, on February 9,1994, Steve !
i Miltenberger, Chief Nuclear Officer-PSE&G, announced, effective immediately, that Cal (
Vondra, General Manapr-Salem Operations was being removed from Nuclear Department ;
- activities and being reassigned to PSE&G's Fossil Department. Joseph Hagan, Vice President- l Nuclear Operations was designated to function as the General Manager-Salem Operations, and l as a Change Agent responsible for initiatives relative to performance improvement. Unitization l of certain functional areas such as Operations, Maintenance, and Station Planning and l l

The licensee also initiated re-evaluation of current managers and supervisors to assure that the individuals were capable of performing to management's expectations, and to replace or reassign the individuals, as necessary. The NRC has noted that actions have already been taken to ;
l
- reassign or otherwise replace several of the incumbents. Other changes to the overall l j organization are expected as the licensee pursues other improvement plan objectives, including !
'(but not limited to) enhancement of personnel performance appraisal review, personnel ;

j in ratings of Category 1 in Radiological Controls and Security, Category 1-declining in l Emergency _ Preparedness, and Category 2 in Operations, Maintenance / Surveillance, !
. Engineering / Technical Support, and Safety Assessment / Quality Verification. There vere !
frequent operational challenges, including nine separate plants trip among the units. The board !
{ '
j concluded that the plant were operated safely and the operator response of operational events was
! excellent. Weaknesses were noted in the licensee's decision-making relative to restart on Unit-2
]
in light of continuing problems with the rod control system, procedural adherence which resulted in loss of Unit-2 Overhead Annunciators, and management oversight of fire protection activities .
which resulted in the improper performance of firewatch activities by contractors. The Board also noted that in several instances, the licensee failed to initiate adequate root cause evaluation or assessment of abnormal conditions; and that NRC interaction with the licensee management I was needed in several cases in order for full evaluation and sufficient corrective action to be accomplished. j
[ The current SALP cycle ends on December 10, 1994. In view of the continuing performance
!' deficiencies, including the findings of the most recent AIT (dispatched to review and assess the i licensee performance. relative to the April 7,1994, Salem Unit-1 trip and consequent plant l stabilization problems), overall performance appears to continue to decline in the areas of Plant
- Operations, Maintenance and Surveillance, and Engineering and Technical Support. Plant
! Support activities appear to be stable. Licensee management is fully cognizant of the problems and have readily acknowledged performance deficiencies in several meetings with the NRC staff.
The licensee appears sincere and is actively engaged in efforts to improve overall performance.

- 3 i
e '
Synopsis: This is a summary of issues and events at Salem which, when viewed in the
,y aggregate, indicate a continuing problem in the licensee's management and ,
oversight and control, and corrective action effectiveness. The following themes ~!
appear to be present: ;
- l. o I Lack of aggressive management oversight of plant activities o Lack of aggressiveness to assure adequate corrective action implementation.
o Inadequate root cause analysis of events o Slow identification and evaluation of degraded plant conditions o Lack of procedural compliance ,
The general response of the licensee relative to these matters is often expressed as:
o Their programs are on improving trends; o They are committed to excellence and plant betterment; ;
o They have improved the quality of their procedures; !
o They are dedicated to better training of their employees; and o They have taken effective action to improve management oversight.
OUTAGE TEAM INSPECTION (October 1988) l Multiple examples of lack of direct management control or effective action with regard to the .
design change / modification / installation process. 50.59 reviews exhibited a lack of attention to !
detail. QA audits identified program problem areas but their effectiveness was minimal due to a lack of management follaw-up to assure corrective action implementation. (IR 88-80)
Licensee responded to the report in a March 1988 letter by indicating that strong and effective action was being taken to resolve the identified weaknesses by:
- reiterating their commitment to excellence in Engineering and Plant Betterment;
- improving the design change control process;
-improving personnel training;
- improving the content and substance of weekly meetings;
- initiating Offsite Safety Review evaluations of management effectiveness.

MAINTENANCE TEAM INSPECTION (Aoril 1990) '
l Several problems were noted regarding adherence to procedural requirements and the !
- effectiveness of controlling contractor personnel. The identification, evaluation, and correction l of deficient conditions were also areas noted to need increased management attention. The report identified several examples of personnel performance errors, particularly in the area of mechanical maintenance. Inadequate root cause analysis was also noted. Quality verification
< activities were identified as being weak. The probability that adverse generic plant material conditions could exist for long periods of time before the licensee is able to discover and correct the problems was noted. A quote from the reports stated, "Although the instances discussed above are not individually significant with regard to safety, the team concluded that the number of examples identified indicated a general failure by licensee and contractor personnel to follow procedures during the performance of work activities." (IR 90-200) 4 INTEGRATED PERFORMANCE ASSESSMENT TEAM INSPECTION (May 1990)
The Team noted a management tolerance of degraded plant conditions and identified a need for improved safety perspective. Weaknesses in management oversight of plant activities, including a lack of field presence were documented, as well as significant weaknesses regarding adequate review and timely implementation of corrective actions. Weaknesses were also observed in procedure quality, procedure implementation, and Incident Report initiation. Misuse and lack of management control of the temporary modification process was noted. The report also noted that several safety tagging errors were not documented by the licensee's incident reports. (IR :
90-81)
- 1 l CATASTROPHIC FAILURE OF THE MAIN TURBINE (November 1993 The Unit 2 main turbine catastrophically failed due to an overspeed condition caused by mechanical binding of turbine control solenoid valves. Root causes were determined to be personnel error, lack of procedural compliance, insufficient supervisory oversight, and lack of l attention to detail. (AIT IR 91-81) l FIRE WATCH FALSIFICATION (1991-1992)
Following an 4cident on July 1,1992 when a contractor (PTI) supervisor noticed that a PTI employee willfully failed to properly complete the required fire patrol, a comprehensive 1 investigation was initiated by the licensee. The licensee subsequently discovered that over half of the contracted firewatch personnel had improperly performed firewatch patrols and had l falsified associated documentation. Previously, the licensee was made aware of a similar issue l through an allegation referred to their attention by the NRC, However, their investigation efforts were not sufficient to substantiate the assertion. The licensee's most recent review of firewatch performance deficiencies noted the root causes to be willful misconduct by contractor employees aggravated by a lack of sufficient management oversight. (IR 92-09)
FAILURE OF OVERHEAD ANNUNCIATORS (December 1992)
ATTACHMENT 1 5 l
1 Unit 2 Operators discovered that the overhead annunciators (OHA) had not been updating alarms
, for about 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> as a result of an operator entering a' keystroke combination into a remote control work station that locked up the system. Root cause was determined to be a failure of personnel to follow procedures relative to use of the computer v-rk station affecting the monitoring and control of the OHA system operation. Further, the jesign of the OHA system l was not sufficient to alert operators to a critical switch that was mispositioned and prevented ;
normal operation. (AIT IR 92-81)
ROD CONTROL SYSTEM FAILURFR (May 1993) l Unit 2 operators experienced several problems with the rod control system; the most significant l being that a rod actually withdrew 15 steps during an attempt to insert Shutdown Bank A. Root j causes were primarily determined to be equipment and design related, however some component failures were attributed to poor work practices during system troubleshooting and testing.
Additionally, the initial management oversight and control of troubleshooting were not sufficient i to assure understanding of the failure causes and establishment of proper corrective measures. l Notwithstanding, the licensee conducted several startup attempts without a concerted effort to !
determine the root cause of the problems. It was not until NRC directly intervened with an AIT that the licensee initiated a thorough and comprehensive analysis of the abnormal performance
, of the rod centrol system. (AIT IR 93-81)
MANAGEMENT MEETING Uuly 1993)
A management meeting was held with the licensee in July 1993 to discuss the licensee's difficulty in resolving problems and implementing effective corrective actions, in light of the three AITs conducted since 1991. In response, the licensee implemented an action plan to
- perform a comprehensive assessment of their performance (CPAT), using several recent events (including the three AIT activities and nine reactor trip occurrences) as indicators of programmatic deficiencies. The purpose of the CPAT efforts was to discover common causal factors that could be associated with the licensee's continuing performance problems, and to establish and implement a corrective action plan to prevent recurrence.
DUTAGE 1R11 WORK CONTROL PROBLEMS (October 1993 - February 1994)
During the conduct of Unit I refueling outage, the licensee and the NRC identified numerous 1 examples of failure to follow established procedures relative to the control of maintenance work I activities. Of particular note was the failure on the part of the licensee to effectively assess these occurrences, determine root cause, and establish appropriate corrective measures to prevent recurrence. Though none of the instances (when considered individually) significantly affected plant safety, several of the items had the potential to affect individual worker safety. (IR 93-23)

k'NFORCEMENT CONFERENCE (February 1994) l Ie
- During the enforcement conference held February 1994, the licensee maintained that
- ;
4 i - the self identification of events process works;
! - procedures are in place to ensure safe practices; j - management presence in the field has increased;
- - there is enhanced review of events at weekly meetings; .
3
- safety stand-downs / training were conducted to reaffirm management expectations; !
- - the contractor work force would be reduced in an effort to better maintain oversight; !
j - the scope of future outages would be limited; and, ,
- personnel accountability for actions will be reinforced.
1 Following the conference, the NRC issued a Notice of Violation and Imposition of Civil Penalty
- ($50,000). _ On April 8,1994, the licensee acknowledged the violations and paid the civil l penalty. The licensee identified the causes of the violations to be related to inadequate
- supervisory methods, insufficient supervisory oversight, inadequate communications of .
l expectations, and failure to follow procedures and established work practices.
e i I OUTAGE 1R11 ISSUES (October 1993 - February 1994) !'
The licensee experienced several difficulties during the outage relative to hardware j modifications. Examples includer p o A auxiliary feedwater (AFW) pump governor, which was previously operating normally l
l and not due for any maintenance, was replaced during the outage due to an error in work i planning. After several unsuccessfully attemps to effect normal operation of the AFW
, pump, and after another replacement of the governor, the licensee determined that the
! replacement parts were different in design than the part that was originally removed.
i Successful operation was accomplished only after the licensee was able to retrieve the i original governor and remount it on the AFW pump. This event may indicate that the i licensee's procurement control program may be defective.
i a e During the outage the licensee aodified the turbine speed control system by changing the
- configuration of the oil pressure control system on the Main Feedwater (MFW) pumps a in anticipation of the installation of a digital feedwater control system during a later 4
outage. Subsequent testing during start-up revealed significant flow oscillations were 1
occurring in the MFW pumps as a result of the modification. After analyzing the cause, j
the licensee determined that the difficulties were associated with the test configuration and the manner the system test was conducted. Notwithstanding, the licensee restored the MFW pumps to the original configuration in order to continue start-up activities.
i e On December 3,1993, during a post-maintenance test on Unit 2, "C" Emergency Diesel Generator (2C EDG) (Note: This is an ALCO diesel; and there are three EDGs per Unit), coolant was noted to be leaking from one of the cylinder liners. Subsequent d licensee investigation revealed that the liner was actually cracked and broken in three
] pieces. During the investigation the licensee determined that the liner was not the ATTACHMENT 1 7 i
[ l l
l l
original equipment and that the 10 or the 18 liners in the 2C EDG were replaced during ;
e a 1992 outage with parts manufactured by Canadian Allied Diesel (CAD), under license ;
by ALCO, in an effort to expedite reassembly of the engine to support plant start-up.
(Note: The original ALCO liners were still being refurbished and were not available for immediate use.) The licensee subsequently shutdown the unit as required by Technical Specifications due to an inoperable diesel. The licensee also determined that all of the cylinder liners in the IB EDG were supplied by CAD due to a similar liner refurbishment effort in 1991. Consequently, that engine was also declared inoperable, which further delayed Unit I restart activities. The licensee conducted a through root cause investigation and determined that there were slight differences in the material and dimensions of the CAD liners, that they did not know previously, that could result in early failure of the part. As a result, the licensee initiated extensive testing and verification, and took action to replace all CAD liners with ALCO manufactured parts.
The licensee's investigation revealed the most probable mechanism that could lead to failure of CAD supplied liners. Consequently, the licensee took actions to improve the quality of its commercial grade dedication process and maintenance procedure. In review, the licensee also discovered that there was no technical or safety basis to refurbish, or otherwise replace any of their diesel liners without cause; and that their rationale that refurbishment or replacement of the liners would result in increased reliability of the engines was unfounded and not demonstrated by industry or vendor experience.
ADDITIONAL SALEM UNIT 1 PROBLEMS SUBSEOUENT TO RESTART ON FEBRUARY 4.1994 After resolving the issues that impacted startup, Salem Unit I was finally, successfully restarted on February 4,1994. However, the following events were subsequently experienced:
- On February 10,1994, after being at power for only 3 days, the unit tripped from 100%.
The plant experienced a coincident loss of both 15 VDC control power supply to the electronic controller associated with the main turbine Electro-Hydraulic Control (EHC) system. Unexpected actuation of the over-voltage protection feature " crowbar", (for reasons still not fully understood but suspected to be associated with vibration caused by maintenance activities in an adjacent equipment cabinet), led to the loss of both redundant power sources. The loss of power caused closure of turbine stop and control valves, leading to turbine trip and resultant reactor trip. All plant systems and emergency safety features operated normally on plant shutdown.
- On February 11, 1994, the licensee discovered that the mode switches for both air compressors on the IB EDG air start system were in the "off" position. Consequently, for some period of time, the air compressors were not replenishing the air receiver tanks for the EDG. Upon discovery, the licensee restored the switches to the proper position and replenished the air supply before it decayed below the pressure necessary to assure EDG start. TK-licensee determined that a maintenance worker failed to restore the switches to th: Wal podon during the performance of a surveillance activity.
ATTACHMENT 1 8
e o On February 13, 1994, I & C technicians were inserting wires in a pressure transducer e associated with the atmospheric steam dump system. Though the technicians believed that they had taken actions to de-energize the cables, they failed to fully understand the circuit completely and recognize that another supply also fed the cables that they were working with. Consequently, the cables shorted to ground and caused the steam dumps to actuate. As a result, an excessive cooldown rate was experienced but manually controlled by reactor operators prior to exceeding technical specification limits.
i However, reactor power was increased from 2% to 5.6% by the event, which constituted an unplanned reactor Mode change from Mode 2 to Mode 1.
MANAGEMENT MEETING. February 24.1994 On February 24, 1994, NRC held a Management Meeting with PSE&G to discuss their intentions, plans and schedules relative to program improvement. The licensee discussed the final results of their CPAT and provided a comprehensive improvement plan and schedule for NRC review and assessment.
The CPAT findings revealed serious deficiencies weaknesses in (1) management skill and practices (including first line supervisory personnel), (2) work processes and controls (including training and communication of expectations to workers), and (3) problem solving and follow-up of planned corrective actions (including root cause assessment, and tracking and trending operating experience feedback. The task for the establishment, implementation, and maintenance of corrective measures has been assigned to a management team. Activities are still in progress.
SAMM UNIT 1 TRIP. Anril 7.1994 On April 7,1994, Salem Unit I tripped from 25% power on a power low range /high flux signal and a safety injection initiation on low-low Tavg coincident with high steam flow. Operators were in the process of reducing power and had declined to below 10% (which enabled the 25 %
low power trip setpoint) to accommodate the loss of some circulating water pumps due to grass intrusion at the intake structure. In order to restore a lower than normal Tavg, the operators withdrew some control rods, which resulted in a power increase to the 25% low power trip setpoint, resulting in an inadvertent trip. The trip was further complicated when at least two main steam isolation valves and two feed water isolation valves failed to close as expected, and the two turbine-driven feed pumps failed to trip. The subsequent cooldown of the RCS caused pressurizer level and pressure to drop. Consequently, another safety injection on low pressurizer pressure was initiated. The plant went solid on high head safety injection pumps. The PORVs opened and relieved pressure to the pressurizer relief tank (PRT). Subsequently, the blowout disk on the PRT released to prevent overpressurization of the tank. The licensee declared an UE and subsequently upgraded the classification to an ALERT during the course of the event.
Several other automatic valves failed to isolate in response to the SI signal. All the affected valves and pumps had to be manually closed or tripped. Pressurizer heaters were turned on to restored pressurizer pressure control. Following, the plant was stabilized and brought to Mode 4, and then Mode 5, without further incident. An AIT was dispatched on April 8,1994, to investigate the cause of the conditions and situations that led to this event.
