'
piping flush procedure on Unit 2 involved the mispositioning of Auxiliary Feedwater system control board valve switches which control the realignment of both Unit 2 motor driven auxiliary feedwater suctions to Nuclear Service Wate Results: Two apparent violations are currently.being considered for escalated enforcemen The first involves the failure to take adequate corrective action in response to a failed surveillance test on. the Unit 2 turbine driven auxiliary feedwater pump. A maintenance work request was not written to document authorization to perform work, maintenance, and retest activities conducted on this componen Actual work conducted failed to identify the root cause of the overspee An adequate evaluation of the failure to justify operability was not performed prior to returning the pump to servic This resulted in the potential inoperability of the CAPT for a period 891003o268 890 2 ,,

b. System Description and Design Basis The Auxiliary Feedwater System (CA) assures sufficient feedwater supply to the steam generators (S/G), .in the event of loss of the Condensate /Feedwater System, to remove energy stored in the core and primary coolant. The CA System may also be required in some other circumstances such as-evacuation of the main control room or cooldown-after a loss-of-coolant accident for a small break', including maintaining a water level in the steam generators following such a brea Three CA pumps are provided, powered from separate and diverse power sources. Two full capacity retor driven ~ pumps are powered from two separate trains of emergency-on-site electrical power, each normally supplying feedwater to two steam generators. One full capacity turbine driven pump, supplying feedwater to the B&C steam generators, is driven from steam contained in either the B or C steam generator Sufficient diversity and redundancy is provided such- that the CA System is capable of delivering the minimum required flowrate to effective steam generators during all modes of operation. The CA System is capable of delivering the required flowrate to effective steam generators at a pressure corresponding to the lowest S/G safety valve set pressure'plus 3% accumulatio Standards for nuclear safety related systems are met- for the CA System except for the condensate quality feedwater source The Standby Nuclear Service water pond serves as the ultimate long term safety related source of water for the syste The mot"r driven pumps will automatically start and provide the ;
minimum required feedwater flow within one minute following any of '
the following conditions:
(1) Two out of four low-low level alarms in any one of the four steam generators; (2) Loss of both main feedwater pumps; (3) Initiation of the safety injection signal; (4) Loss of station normal auxiliary electric power; (5) ATWS Mitigation System Actuation Circuitry (AMSAC) start signal.

to steam generators effective in cooldown and does not include flow delivered to a steam generator involved in a feedline to CA line i break. Accidents analyzed for in Chapter 15 of the Final Safety Analysis Report (FSAR) typically assume a minimum CA flow of 491 gallons per minute (gpm) delivered to two intact steam generators with no operator action for 30 minute For the postulated non-seismic event of loss of all offsite and all onsite emergency A.C. electrical power, the CA System will perform its safety related function. This assessment includes the limitation that no single failure that would prevent the single A.C. power independent turbine driven pump subsystem from functioning occurs during this limiting even The turbine driven pump (CAPT) consists of a direct coupled, single j stage Terry turbine rated at 3600 revolutions per minute (RPM) with a l Bingham horizontal seven stage centrifugal pump. The speed of the turbine is determined by the position of a steam governor valve which is controlled by a Woodward governor. The. governor is of the mechanical hydraulic type, driven by the turbine rotor through spiral reduction gears. The centrifugal force on a set of flyweights moves a spring loaded servo piston rod which. controls the flow of hydraulic fluid to the power cylinder assembly (remote servo) which provides linear motion as the output of the governor. The work capacity of the remote servo is 29 foot pound A connecting rod transmits linear motion between the power cylinder assembly and a slotted cam crank. A cam roller is connected to the end of the governor valve stem and is inserted through a bushing into the slo The slot is angled such that vertical motion of the connecting rod and cam crank is transmitted as horizontal motion to l the governor valve ste '
i
~ The turbine is protected from overspeed by one electrical and one mechanical overspeed sensing device. The mechanical overspeed device setpoint is 125% (4500 RPM). Centrifugal force of the rotating turbine shaft causes displacement of the pin type trip weight outward from the shaft axi The pin strikes a ball tappet, lifting it upwards overcoming tappet reset spring force. This releases a spring loaded head lever and connecting rod which causes the turbine trip and throttle valve to close. The device must be reset locally at the turbine.

c. Event Description On July 31, 1989, Catawba Unit 2 was operating at 98% power. At 1:10 p.m. operations personnel were attempting to perform a routine surveillance test on the turbine driven auxiliary feedwater pump (CAPT). On the first two attempts to start the pump, it oversped and tripped mechanically. A Maintenance Engineering Services engineer (NES) was requested to assist in determining the nature of the overspeed problem. At 1:20 p.m. another start attempt was made which also resulted in the pump tripping on mechanical overspeed. The engineer observed during the third attempt that the governor valve control linkage did not move to control turbine speed as designe The engineer " exercised" the linkage using a screwdriver and another pump start was attempte The pump performed acceptably during this attempt, was declared operable and returned to servic It was subsequently learned that the work performed on the CAPT had been performed without' permission, with no work. request or procedure, in violation of the licensee's Maintenance Progra The residents became aware of the event on August 1, during the morning status meeting. Discussions with licensee management at that time revealed that they did not have enough information to discuss the issue in detail, that the (MES) group had been working on the issue, and that any specifics relative to the event would have to come from the aforementioned MES enginee The MES Supervisor was requested at that time to have the engineer contact the resident The system engineer called the residents the next day, August During the conversation, it was learned that:
The system engineer determined during conversations earlier that day with a representative of the company which manufactured the turbine, that the lutricant being used on the control linkage, N5000, was not recommended for that applicatio The event appeared to have been caused by the use of improper l lubricant on the governor / control valve linkag i Although the lubricant problem was germane to both units, there had been no action to verify that the unit 1 CAPT was still operabl The lubricant was to be changed out on both units beginning on or about August 1 *
Other than exercising the linkage on the Unit 2 CAPT no corrective action had been performe j The residents voiced their concerns, at that time, relative to the operability of both units' CAPT These concerns were based on the fact that the apparent root cause of the problem had apparently been identified. The problem had resulted in the inoperability of the Unit 2 CAPT, yet the licensee had not implemented immediate

corrective actions to ensure that both units' CAPT's remained operable unt.il the lubricant could be changed, j i
On the following afternoon, representatives of the licensee's staff, i including the MES engineer, met with the residents to discuss the residents' concerns. During that meeting, it was confirmed that: 3
The apparent root cause of the problem was the use of the N5000 lubrican The licensee had, by August 3, performed a visual examination of j the linkage on the unit 1 CAPT, but had not checked the linkage i for frcedom of movement nor otherwise verified its operabilit ]
The schedule for the lubricant replacement had been moved from August 10 to on or about August ,
No additional corrective actions or testing had been performed on the unit 2 CAP l
The residents reiterated their concern over the operability of the CAPT's, in that the problem had not been resolveo, yet no immediate corrective actions or evaluation had been performe The residents !
also asked if the licensee had planned to perform pre-maintenance '
tests on the CAPT's. The licensee informed the residents they had !
not but indicated that they would consider the These tests would i verify the operability of the CAPT's from the time of the identification of the problem until the corrective maintenance was complet l On August 5 at 8:42 p.m. the Unit 1 CAPT was run successfully.for a pre-maintenance verificatio The governor valve linkage was disassembled, cleaned, lubricated with Neolube 2, and reassemble The turbine was retested and returned to service at 12:45 a.m. on j August On August 7 at 9:50 a.m. a pre-maintenance verification test was attempted on the Unit 2 CAPT. The turbine oversped and tripped on electrical overspeed. It was observed that the control linkage moved too sluggishly to control turbine speed properly. At 10:07 a.m. the CAPT was restarted at which time it ran successfully. The governor valve linkage was then disassembled, some parts replaced and lubricated with Neolube 2. It was also found that the governor valve stem had suffered corrosion attack in the area of the stem packin The valve stem was replaced and at 10:30 a.m. on the trorning of August 9, the Unit 2 CAPT was returned to servic ,

operable but have concerns related to it, necessary actions I shall be taken expeditiously to resolve the concerns, identify any root cause, and confirm operability. These actions shall include additional testing, engineering evaluations, and ;
calculations or inspections as appropriate to the circumstance '

corrective actions being performed to assure the pump was in i fact operable, e. Safety Significance Issue 1 On July 31, the Unit 2 CAPT tripped on mechanical overspeed on an attempted start. An immediate attempt at a second start was 1 also unsuccessful. A third start attempt was made with an MES l Engineer, an Operations Engineer, and a Maintenance Planner observing the activity. Again, the pump tripped on mechanical overspeed and it was observed that the control valve linkage did .
not move. The CAPT control valve linkage was then manually I exercised. The CAPT was started, the linkage responded to control turbine speed, and successfully met the requirements of ,
the monthly surveillance tes Based on having passed the surveillance test, the CAPT was declared operable and returned to service. It was subsequently determined that a work request i was not initiated when the turbine trip occurred, and was not used in investigating the proble The safety significance of this issue concerns the " corrective maintenance" performed by the MES Engineer when he exercised th control valve linkag Not only war it inappropriate to simply dislodge the stuck linkage but the failure to initiate a work request circumvented the normal process of evaluating equipment operabilit It is expected that problem resolution be performed under the appropriate programs to ensure that underlying problems are identified and resolved and that an operationally reliable component is returned to service. ' Given the circumstances of this event it is not clear that the CAPT was fully operable when returned to service on July 31, 198 _ _ _ - _ _ -

Issue 2 The CAPT oversped at 1:11 p.m. on- July 31, passed its surveillance test at 1:25 p.m. that afternoon and then oversped again at 10:00 a.m. -on August 7. The surveillance . test performed is termed a " slow start" as the turbine is started with the speed control potentiometer set at minimum' speed, then slowly increased to maximum speed by the operato The safety significance of this issue concerns the fact that normally with the CAPT in standby, a safety _ signal will cause.it to " fast start", or immediately ramp up to operating speed in approximately 30 seconds. The inspectors were concerned with the adequacy of the surveillance to demonstrate the ability of the CAPT. to perform its intended safety- function in that a fast
~
start was not performed and-the governor: linkage-was exercised prior to performing the -test. Discussions with the responsible licensee engineer indicated that in this particular event, it would- not have mattered whether a slow or fast start was conducted due to the fact that the failure mechanism of. stem corrosion prevented the governor valve .from closing. Slow-starts, however, may not be appropriate for operability testing, as governor problems could potentially remain undetecte Issue 3 On July 31, 1989, the unit 2 CAPT tripped a number of times on mechanical overspeed, was returned to service and tripped on overspeed again on the next start attempt on August 7,'198 On August 1, at 4:50 a.m., the Unit 2 Motor Driven CA Pump 2B was. removed from service to repair an oil leak on the bearing housing drain plugs. Repairs were completed and the pump was returned to service at 3:00 p.m. the same da On August 2, at 3:00 a.m., Nuclear Service Water (RN) . System Train B was removed from service for repairs. With RN Train B inoperable, both Unit 1 and Unit 2 Train B Diesel Generators .
were inoperable due to RN cooling water not being availabl With the Diesel Generators inoperable, essential' power could not be provided to the Unit 1.or Unit 2 CA B Pumps, which were also considered to be inoperable. On August 4, at 8:00 p.m.., RN repair work was complete and the CA Train B Pumps were returned -
to operable statu The safety significance of this issue concerns the inoperability of 'the Unit 2 B Train CA Pump during the time the CAPT was in questionable status. Thus, the potential existed for having two auxiliary feedwater pumps inoperable.

Work was expanded to include rebuilding the control valv It was.at this time that it was identified that indeed the event
~
of July 31 may have been caused by binding of this valve due to corrosion rather than the linkage / lubricant proble The safety significance of this issue concerns the operability of the Unit 2 CAPT during the period of July 31 through August 9,1989. In as much as no corrective maintenance was performed on July 31 and the CAPT failed to operate properly on August 7, it raises the concern about the pump's operability due to no corrective action 'being accomplished prior to returning it to service. During this_ period, the Unit 2 B train ;
motor driven CA pump was also inoperable from 4:50 a.m. until 3:00 p.m. on August 1 and -from 3:00 a.m. on August 2 until 8:17 p.m. on August f.

Auxiliary Feedwater Suction Valve Event Executive Summacy On September 12, 1989, the Resident Inspector discovered that Unit 2 ;
control board switches for ' valves which automatically align the l suction of both Unit 2 motor driven auxiliary feedwater pumps to the !
system's only safety related, assured suction source, had been '
mispositioned such that automatic realignment on a low suction pressure would not occu It was determined that the switches had been mispositioned some 30 minutes prior to discovery during the i performance of a piping flush procedure. During this time, the i turbine driven auxiliary feedwater pump was also inoperable for maintenance. The mispositioned switches were immediately identified j!
to the Shift Supervisor, and they were placed to the AUTO position l which in turn returned the motor driven auxiliary feedwater pumps to operable status, Event Description On September 12, 1989, during a routine control room tour, the Resident Inspector detected that the Unit 2 Control Room System Bypass Panel (installed in accordance with Regulatory Guide 1.47) ;
indicated that all three Auxiliary Feedwater (CA) pumps were 1 inoperable. The system is comprised of.a turbine driven pump (CAPT)- <
and two motor driven pumps. It was also determined that the CAPT was inoperable due to ongoing maintenance. The inspectar questioned the Unit 2 Operator at the Controls (0ATC) as to why br/d motor driven CA pumps indicated inoperable. The 0ATC was aware of the indications and considered the cause to be associated with valve manipulations performed to facilitate the ongoing flush of the Nuclear Service i Water (RN) to CA snction lines. The operator was not sure, however, which component realignments were causing the bypass panel indi-cations. At the inspectors request, the 0ATC reviewed applicable ,
logic diagrams and determined that the motor driven CA pump flow '
paths were inoperable due to the. control board switches for valves 2CA-15 and 2CA-18, the CA pump 2A and 2B suction isolation valves from RN, being in the "CLOSE" position. These switches have three positions: OPEN, AUT0, and CLOSE. The valves are normally closed

i with their switches in AUTO. The safety' related function of these valves is to open automatically upon a low CA suction pressure in order to supply RN to the CA system. The four normal condensate-grade suction sources for CA are neither safety related nor seismi RN is the only safety related assured suction source.to CA. The inspector immediately informed thel Shift Supervisor of the identi--
fication that both motor driven CA pumps were inoperable'due to the inability to automatica11y' swap to RN on a low suction pressure I condition.- The Shift Supervisor concurred and had the 0ATC place the-switches for 2CA-15 and 2CA-18 in the AUTO position at approximately ;
2:10 p.m., some 35 minutes after the switches had been misa11gne I At this point the System Bypass Panel lights for Train A and Train B CA went out indicating that both trains had been returned to servic The inspuctor reviewed the ongoing flush procedure, PT/2/A/4200/59, RN to CA Piping Flush. Step 12.2.6 of that procedure requires the operator to " Ensure the following valve are closed: 2CA-15 and 4 2CA-18." At 1:35 p.m., upon performing this step, the 0ATC ensured the valves were closed by observing the control board indicating light However, she also incorrectly decided to assure the valves would not inadvertently oper by taking the aforementioned switches from AUTO to CLOS This would have prevented the automatic opening-of these valves in the event of a low suction pressure condition. It should be noted that this step was also independently verified by a-non-licensed operato Further review of the procedure revealed that both 2CA-15 and 2CA-18 are cycled open and closed after the flus The switches are then placed in AUTO. These steps were performed.at or about 12:26 the next morning, September 13. Based solely-on the time that this particular procedure step was performed, the potential existed to have all three CA pumps inoperable for a period of approximately 11 1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, had the error gone undetected.

Even though the operator was aware that all three auxiliary feedwater pump lights on the Unit 2 Control Room' System Bypass Panel were illuminated, the operator failed to recognize the significance of the indication The operator. therefore, failed to immediately initiate corrective action to restore at least one auxiliary feedwater pump to an operable status until 2:10 p. when the inoperability was identified by the NRC inspecto Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained covering the activities referenced in Appendix A of Regulatory Guide 1.33, Revision 2 February 1978, which includes the operation and testing of safety related equipment.

Contrary to the above, the 0ATC failed to follow procedures in that the 0ATC:
(1) was not knowledgeable of the unit status; (2) did not operate the unit in compliance with technical specifications; (3) did not ensure that the " Control Room Supervisor" was notified of the abnormal condition indicated on the R.G. 1.47 panel; (4) did not initiate prompt corrective action to a received alarm; (5) did not notify the " Control Room Supervisor" of the unexpected alar This is required by Operations Management Procedure 1-0, Section 7. Operator At the Control d. Safety Significance Issue 1 At approximately 1:35 p.m. on September 12, 1989, the Unit 2 0ATC misaligned the switches which control valves 2CA-15 and 2CA-18, the CA suction isolation valves from RN, such that the valves would not have automatically opened on a low suction pressure signal. This action rendered both motor driven CA pumps incapable of performing their intended safety function under certain conditions. The turbine !
driven CA pump was inoperable for maintenanc Thus, for some 35 minutes, all three CA pumps were inoperabl l The safety significance of this issue concerns the inoperability of !
