AUSTRACT IOWER LEVEL - 010%. ON s'UNE I.

1994. A REACTOR TRIP OCCURRED.

THE RUOT CAUSE WAS DETERMINr0 TO STEM FROM A PERSONNEL ERROR THAT RESULTFD IN REACTOR F OWER REACHItJG 10% WITH THE TURDINE IN A TRIPPED CONDITION AND OCCURRED DURING ATTC MPTS TO OPEN THE MAIN STEAM ISOLATinN VALVES (MSIVS).

THE MSIVS ARE OPENED ONLY AFTER EOUALIZING THE STEAM tiENERATOR PRESSURES WITH THE STEAM HEADER PRESSURE.

THIS IS ACCOMPLISHED BY OPENING THE ASSOCIATED DYPASS VALVES AROUND THE MSIVS AND INCRFASING ATNO'PHEPIC STEAM DUMP IN THE RESPECTIVE HEADERS TO REDULE 1HE iRESSURL UPSiREAM OF THE MSIVS.

THE STEAM llSAGE ASSOCIATED WITH EQUALIZING THE STD M PRESSURE ACRO?S THE NSIVS REDUCES THE AVERAGE REALTOR COOLANT SYSTEM TEMPERATURE (TAVG). DURING ATTEMPTS TO UPEN THE MSIVS. THE LICfNSED OPERATOR INCREASED REACTOR POWER IN ANTICIPATION UF A 'AGGEl. ING T ( AVG ).

HOWEVEP. DEACTOR POWER REACHED 10% DURING THE EVOLUTION AND STNCE THE TURBINE WAS IN A TRTPPFD i.ONDITION. A REACTUR TRIP RESULTED. ALL EOUIPt'ENT FUNCTIONED A9 L'ESIONED nN INITI AT ION ' T THE E NGINEERED SAFETY FEATUPE ACTUATTON alGNAL (ESFAS) GENTAATEl: IN THE REACTOR PROTECTION SYSTEM.

ABSTRACT

[

POWER LEVEL - 100%. ON 2-10-85. THE 4A CONTAINMENT SPRAY PUMP POWER gg SUPPLY BREAKER WAS FOUND TO BE INOPERADLE.

T F.

- CSP 400V POWER SUPPLY BREAKER CLOSING SPRINGS WERE FOUND DIP HAPGED AND THE CLOSING SPRING CHAROING MOTO7 WAS TURNED OFF. THEREFORE, THE PUNP POWER 90PPLY gg BREAKER WOULD NOT HAVE CLOSED IN RESPONSE TO A PUMP START SIONAL.

THIS RENDERED THE PUMP INuPERABLE FOR A PFRIOD OF TIME THAT FXCFFDFD THE TECH SPEC LCO.

AT THE TIME OF THIS EVENT. THE 4B CSP AND THF gg EMERGENCY CONTAINMENT COOLING SYSTEM WERE FULLY OPERATIONAL.

SIGNIFICANT EVENT NOTIFICATION WAS MADE TO THE NRCOC VIA ENS PURCUANT TO 10CFR50.36(C)(2).

SIM'LAR LERS 251/83-017 AND 251/83-014 gg INVESTIGATIONS HAVE DISCOVERED THAT THE LAST OPERABILITY TEST OF THE 4A CSP OC(URRED ON 2-6-85.

IT IS BELIEVED THAT THE CLOSING SPRING CHARGINO NOTOR WAS OFF DU11NG THIS TEST RESULTINO IN THE CLOSING SI' RINGS DEING DISCHARGED.

ONE POSSIBLE REAsnN FOR THE CHARGING MOTOR BEING OFF WAS 1 HAT AFTER AN IN-PLANT CLEARANCE ORDER FOR THE POWER SUPPLY BREAAER WAS RFLEASED ON 2-3-85. THE SWITCH FOR THE CHAROING gg MOTOR HAD DEEN'INADVERTENiLY LEFT IN THE OFF POSITION. ANOTHER POSSIBLE f,EASON COULD BE THAT THE SWITCH WAS ACCIDFNTLY DUMPFD TO OFF by CONSTRUCTION WORKERS SOMETIME BEFORE THE 4A CSP OPERADILITY TEST ON gy~

2-o-85.

a MAINTENANCE 1.

The lack of evaluating the root cause of equipment failures and not trending these failures to provide input into the preventive maintenance program was considered a significant weakness. The Plant Work Order (PWO) forn is used to document the performance of maintenance and a section of this form is provided to describe the cause or reason for the trouble found. A review of completed PWO forms revealed that the cause of the associated equipment failure was described in very few cases.

Interviews with neintenance supervisory personnel revealed that the cause of equipment failures and the consideration of the recurrent nature of failures are tracked informally by relying upon the memory of maintenance suprevisors. The machinery history records were not being kept up to l

date in the electrical and mechanical areas.

An extensive review of the reintenance history records for the auxiliary feedwater (AFW) system, which included PW0s and Licensee Event Reports (LERs), revealea a number of component failures of a recurrent naturg.

These included seven separate examples, since January 1984, of the failure of an air-operated AFW flow control valve to properly function due to water or foreign material in the supply air.

l l

l

l 1

In 1983, on two separate occasions, two of the six aux 11ary feed steam supply motor operated valves (MOVs) failed to open because of carbon l

butid-up on the motor operator limit switches. A search of the

)

maintenance records for the remaining tour auxiliary feed steam supply MOVs revealed that, despite the recent failures mentioned above, MOV 3-1404 had not been electrically cleaned and inspected since October 1981 and MOV 4-1404 had not been electrically cleaned and inspected since 1979. Several additional weaknesses associated with maintenance on MOVs are discussed in observations 2 and 3.

2.

A review of the maintenance activities performed on MOVs revealed weaknesses with training for the repair of these valves. Interviews with I

supervisory maintenance personnel revealed that no training has been conducted in either the mechanical or electrical areas on the repair of MOVs with the exception of undocumented, on-the-job training and pre-maintenance briefings. A mock-up of a Limitorque valve operator was available in the training department offices but apparently had not been used to train maintenance personnel.

3.

Of significant concern was the uncertainty on the part of mechanical main-tenance personnel of the type of grease used in MOV gearboxes. This is considered a problem for two reasons. First, the mixing of different types of grease in the gearbox could cause hardening or separating of the 'rubri-cant. The potential for this exists at Turkey Point because their preven-tive maintenance instructions for Limitorque gearboxes specify the use of Texaco Marfac and these same Limitorques are known to have been supplied with either Exxon Neb'ala EPO or EPI or Sun 50 EP lubricants. Secondly, the

r only Limitorque lubricant that meets the environmental qualification re-i quirements of 10 CFR 50.49 at Turkey Point is Exxon Nebula EPO or EPI.

The ifcensee had previously identified the problems-discussed above l

regarding Limitorque lubrication. A program to address these concerns is underway and scheduled for completion by December 1986. The progress of this effort will be tracked by the NRC Region II Office (50-250/85-XX-XX, i

50-251-XX-XX).

4.

Although several of the previous observations may indicate a general weakness regarding MOV maintenance, the licensee has recently taken some positive steps to improve MOV reliability. Temporary Operating Procedure 166 was issued in May 1985 and provides detailed instructions for trouble-shooting and repair of MOVs including limit switches, torque switches, and post-maintenance testing. This procedure provides specific torque switch settings for safety-related motor operated valves and the require-ment that, during maintenance, proper torque switch setting be verified i

by an electrical quality control inspector. Discussions with management representatives revealed that the licensee is in the process of purchasing j

some relatively new and innovative MOV test equipment in order to improve 1

the the reliability of their MOVs.

5.

A review of calibration records revealed that the low pressure alarms for i

l the AFW nitrogen supply system are not routinely calibrated. This nitrogen i

l j

supply system provides the capability to operate the AFW system flow con-

\\

l trol valves in the event of a failure of the non-safety-related instrument l

6 air system. These alarms, set a 500 psi, require local manual acti:,n to valve in or replace a new nitrogen supply cylinder. A search of calibrat-ion records with the assistance of an Instrument and Control (ISC) super-visor revealed that the last available records of the calibration of PS 2322 and PS 2323 were dated June 14, 1978. In addition, no procedure was available for the calibration of these alanns. The apparent failure to periodically calibrate these instruments and provide a procedure for this 1

purpose was discussed with the Itcensee and will remain unresolved pending followup by the NRC Region II Office (250/85-XX-XX, 251/85-XX-XX).

6.

The control and docu.nentation of post-maintenance testing was found to be weak. In many cases, neither the instructions outlining appropriate post-maintenance testing nor the results of the testing performed were i

documented on the Plant Work Order. This was particularly evident for I&C and electrical-related maintenance activities. Administrative Procedure (AP) 0190.28. " Post Maintenance Test Control," was specified on the PWO in most cases involving mechanical-related maintenance. This procedure describes much of the testing considered adequate to return mechanical systems to operability and provides a form to document the test results which is then attached to the PWO.

The apparent failure to provide adequate instructions for post-maintenace testing on the PWO appears to be contrary to AP 0190.19 " Conduct of Maintenance on Nuclear Safety Related and Fire Protection Systems," was discussed with the licensee, and will remain unresolved pending followup by the NRC Region II Office (250/85-XX-XX, 251/85-XX-XX).

7.

A weakness was noted in the program to ensure that instruments are properly returned to service following maintenance or calibration while the plant is operating. The ifcensee had a program for providing general assurance that instruments inside and outside the containment are properly aligned when the plant is returning to operation from an outage condition. The procedures describing the instruments to be checked, 0-SMI-059.1 and 0-SMI-059.2, were generally adequate, providing a place for first and second r. heck verification for each appifcable instrument.

Inteviews with I&C supervisory personnel revealed that these procedures would nomally be used only to verify instrument alignment at the end of an outage condition. Instrument line-ups were not required by the licensee to be independently verified following maintenance or calibration when the plant is in an operating status. Of additional consideration in this issue is the fact that 14 of 34 I&C maintenance technic'ans at the time of this inspection had less than one year experience at Turkey Point.
