Statement of Violation: failure to follow an Approved Procedttr.c _.

Technical Specification G.8.1.d requires that written procedures shall be established, implemented, and maintained for Emergency Plan implementation.

This is accomplished, in part, by Procedure OERP01-ZV-I!101, Revision 0, " Emergency Classification."

Addendum 1 of Procedure OERP01-ZV-I!i01 requires that an - Unusual Event be declared when all engineered nafety features diesel generators are inoperable.

Contrary to the above, on October 12, 1992, Unit 1 control room operators failed to declare an Unusual Event until 4 hours and 22 minutes after it was determined that all three engineered safety features diccol generators were inoperable.

This is a Severity Level IV violation.

(Supplement I) (498;499/9229-01) II.

Itouston Idghtina & Power Position: IIL&P concurs that the cited violation occurred.

III.

ILeason for Viojation: The cause of the failure to immediately declare an Unusual Event was that Control Room operators did not recognize that the Emergency Classification prc.cedure, OERP01-ZV-IN01, required entry into an Unusual Event.

Operators are trained on the requirements of the Emergency Classification procedure, however, they are not required to memorize it.

When a component is declared inoperable it is entered in the Operability Tracking Log (OTL). The standard.OTL for Standby Diesel Generators (SDGa} did not provide any guiCance which would prompt operatorc to review the Emergency Classification procedure.

In addition, there is no requirement in the Technical Specifications for an SDG to be operable when the Unit is in no mode (no fuel in the reactor vessel). If all three SDGs were inoperable in Modes 1 through 4 then a shutdown and/or cooldown to Mode 5 would be required by Technical Specifications.

Operations personnel are confident that if this event occurred in Modes 1 through 4 then Control Room perconnel would have recognized that an Unusual Event should be entered.

The Emergency Classification procedure does not account for the different mode requirements of Technical Specifications.

Attachment 1 ST-llL-AE-4278 l Page 2 of 2 IV.

Corrective Actionn:

The following actions are being taken to prevent recurrence 1. The Operability Tracking Log for SDGs was revised to require the operators to review the Emergency Classification procedure for possible Emergency Plan entry requirements.

2. The Emergency Classification procedure was reviewed to determine if any other conditions could exist which would result in the f ailure to enter the proper Emergency Action ' Level.

As a result, OpOp04-DJ-0001, Loss of Class 1E 125 VDC Power, was revised to reference the Emergency Classification procedure.

! 3.

Shift Supervisors for both Units completed required , reading of the Emergency Classification procedure.

4.

This event will be included in Licensed operator Requalification training.

Training will be completed by March 12, 1993.

5.

Lesson Plans for Emergency Plan implementing procedures will be revised by January 25, 1993 to ~ emphasize that Emergency Plan requirements are in effect at all times, including no mode.

V.

Date of Full Comollance: HL&P is in full compliance at this time.

Future training will reinforce Emergency Classification requirements.

Statement of Violation: Failure to Follow Anoroved Procedures Technical Specification 6.8.1.a requires that written procedures shall be established, implemented, and maintained for those activities recommended in Appendix A of Regulatory Guide (RG) 1.33, Revision 2, February 1978.

Three (sic) examples of violating this requirement are stated below: 1.

RG 1.33, Appendix A, Item 3.e, recommends operating procedures for the component cooling water system.

This is accomplished, in part, by Procedure 1PCP03-ZC-0002, Revision 0, " Chemical Addition to Component Cooling Water System."

Step 4.2.11 of Procedure IPCP03-ZC-0002 requires plant operators to place the control switch for the Domineralized Water Makeup Valve 1-CC-LV4501 to the proper position for plant operation (automatic) following chemical addition to the component cooling water (CCW) surge tank.

Contrary to the above, on October 3, 1992, Unit 1 control room operators fai. led to restore Valve 1-CC-LV4501 to the automatic position - following chemical addition to the component cooling water surge tank.

Consequently, on October 4, 1992, the Train A component cooling water system automatically isolated on low surge tank level and the Train C CCW Pump started because of low system pressure.

2.

RG 1.33, Appendix A, Item 3.s(2) (a), recommends operating procedures for onsite emergency power sources.

This is accomplished, in part by Procedure OPOF02-DG-0002, Revision 0, " Emergency Diesel Generator 12(22)."

Step 4.11 of Procedure OPOP02-DG-0002 requires depr_essing-the release pushbutton prior to resetting the emergency stop pushbutton.

Contrary to the above, on October 15, 1992, a Unit 1 control room operator failed to depress the release pushbutton prior to resetting the emergency stop pushbutton.

Consequently, Emergency Diesel Generator 12 inadvertently started when the emergency stop was reset.

This is a Severity Level IV violation.

Itouston Lichtinri & Power Position: 11L&P concurs that the cited violation occurred.

III.

Roacon for Violation: 1.

Sco attached LER 92-016.

2.

The cause of the inadvertent Standby Diesel Generator (SDG) start was the failure of the Reactor Operator (RO) to follow the procedure precautions.

The RO reviewed the procedure in preparation for the evolution, however, he did not consult the procedure during restoration of the SDG and did not recall the procedure precaution.

IV.

Correqtive Actions: 1.

See attached LER 92-016.

2a. The SDG operating procedures were revised to include specific steps to restore the SDG, including releasing the SDG from the emergency modo prior to resetting the emergency stop pushbutton.

2b. The personnel involved were counseled in accordance with the Constructive Discipline Program.

2c. Engineered Safety Features (ESP) actuations were discussed with each crew by Operations Management.

2d. A Unit Supervisor mooting was held on October 19 to discuss supervisory oversight expectations.

2c. A new interim procedure review and feedback form was developed to be completed prior to and after each evolution.

The form provides ESF awareness questions and spe'ific feedback for procedure improvement.

c 2f. Engineering will evaluate a design change of the SDG circuitry to automatically release the SDG from the emergency mode when the SDG is tripped using the emergency stop pushbutton by January 31, 1993.

The design change will be dispositioned by management by February 26, 1993.

The Demineralir.ed Water makeup valve to the Component Cooling Water (CCW) surge tank had been isolated the previous -day, in preparation for an addition of' corrosion inhibitor.

At_approximately 0318 hours, Unit 1-experienced an unplanned Engineered Safety Features (ESF) actuation due to an automatic pump start of CCW components caused by a low level in the-CCW surge tank. The appropriate of f-normal procedure was implemented and.

level in the surge tank was restored without further incident.

All ESF equipment operated as designed.

This event was the result of a failure to reopen the CCW surge tank makeup valve following a-chemical addition.- The immediate iause of this event is less than adequate communications.

An additional cause was the lack of a procedural step to verify valve position.

This event will be included.in requalification training for licensed and non-licensed operators,_ chemical operators and chemistry technicians.

The procedure associated with this surveillance will-be revised to include a requirement for verification when - manipulating.

safety related valves.

Additionally, a review will be performed-of - procedures that contains Operations and Chemistry interfaces to ensure adequate independent verification is specified for those systems that-require-verification of valve-positioning.

At approximately 0318 hours, Unit 1 experienced an unplanned Engineered Safety Features (ESP) actuation due to an automatic pump start of Train "C" CCW components caused by a low level in the CCW surge tank.

On October 3, 1992, at approximately 1530 hours, the Domineralized Water makeup valve to the Component Cooling Water (CCW) surge tank was isolated in preparation for an addition of corrosion inhibitor.

The procedure in use directed the Chemical Technician to notify the control Room upon the completion of the chemical addition and to further instruct the Control Room Operator to place the makeup valve in the proper position.

From the statements made by the Chemical Technician, the requirement to reposition the valve was relayed by the Chemical Technician to the Control Room and acknowledged by an unknown individual.

No Control Room Operator on shif t at the time recalls receiving direction to close the valve but all personnel interviewed acknowledged that-multiple refueling outage activities were in progress.

The CCW system supplies both ESF and non-ESF loads and contains a surge tank to maintain system inventory.

The CCW surge uank is compartmented into three equal volumes by internal baffles such that a leak on any one train will not disable all three.

Makeup to the CCW surge tank is automatically initiated from the Domineralized Water header at a preset value through the Domineralized Water makeup valve.

In the event that the level continues to decrease, non-ESF components are isolated and the CCW trains are isolated from each other via automatic valve closure.

Automatic start of the Standby CCW pump occurs when the CCW common header pressure drops to a preset setpoint.

At approximately 0318 hours,on October 4, 1992, Unit 1 experienced a low level in the CCW surge tank and an automatic start of the C Prior to this time, CCW pump 1A was providing train (1C) CCW pump.

while IC needed CCW header flow for refueling outage heat loads, was in standby, and 1B was in maintenance.

The low level was caused by normal system losses coupled with the lack of makeup flow.

Prior to reaching the non-ESF isolation setpoint, an alarm should have been generated.

However, this alarm was inoperative LER\\92297002.U1 -..

The off-normal procedure, Loss the actuation of the Train C pump.

of component Cooling Water, was implemented and level in the surge tank was restored without further incident.

CAUSE OF EVENT: 'This event was the result of a failure to reopen the CCW surge tank The immediate cause of fill valve following a chemical addition.

An additional this event is less than adequate communications.

cause was the lack of a procedural step to verify valve position.

Reliance on a single procedural step notifying the operator of the need for valve restoration ir not sufficient.

This event indicates the potential that other procedures involving operations and Chemistry interfaces may not have adequate verification specified.

The cause of the annunciator failure was a loose microswitch connection was repaired and tested This connection.

The level switch that generates the alarm had not satisfactorily.

ANAI,YSIS OF EVENT: The CCW pump start is considered to be an ESF actuation and is reportable pursuant to 10CFR50.73 (a) (2) (iv). The CCW system supports the ESF functions of systems as described in the STPEGS All ESF equipment operated Updated Final Safety Analysis Report.

The failure of the annunciator exacerbated the incident but did not constitute a significant challenge to the CCW system.

CORRECTIVE ACTIONS: 1. CCW surge tank level was recovered and the CCW system was realigned in accordance with procedure.
