==Dear Mr. Langenbach:==
==Dear Sir:==
This refers to the inspection conducted between September 7,1997, and November 1,1997, at the Three Mile Island Nuclear Station in Middletown, Pennsylvania, the findings of which were discussed with members of your staff during an exit meeting on November 13,1997.
Subject: Three Mile Island Nuclear Station, Unit 1, (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Response to Notices of Violation (NOV) 97-09-02, dated January 27,1998 And NOV 97-10-01, dated February 26,1998 The attachment to this letter transmits the GPU Nuclear (GPUN) Inc. responses to the NOVs referenced above. Each violation identified in the NOVs is addressed separately to include: (1)
the reason for the violation; (2) corrective actions taken and results achieved; (3) corrective actions to be taken, if applicable, to avoid future violations; and (4) the dates of full compliance achievement. The public health and safety were not affected by these events.


During the inspection, apparent violations were identified related to your activities during the 12t refueling outage. The inspection report addressing these issues was previously
The two violations involved procedural non-compliance and usage issues. While we determined that the root causes for each event were different, we have concluded that programmatic improvements should be considered in addition to the specific actions identified in this response.


forwarded to you on December 2,1997. On December 22, 1997, a predecisional enforcement conference (conference) was ennducted with you and members of your staff, to discuss the violations, their causes, and your corrective actions.
We plan to expand the list of applicable procedures required by administrative controls to be carried and signed off during performance of plant evolutions by June 30,1998. We also plan to conduct a self-assessment and benchmarking review of the procedural controls currently in place. The review will consider industry guidance and good practices employed by other nuclear plants to determine what changes should be made to improve procedure control or usage at TMI.


Based on the information developed during the inspection and the information that you provided during the conference, three violations of NRC requirements are being cited and are described in the enclosed Notice of Violation (Notice). The circumstances surrounding the violations are described in detail in the subject inspection report. The violations involve: (1)
The target date for completion of this review is September 30,1998. A schedule for the development and implementation of requisite improvements is expected to be in place by October 31,1998.
inadequate post maintenance testing following replacement of the pressurizer power operated relies' valve (PORV), in October 1995, that resulted in failure to detect that the PORV actuation circuit was miswired rendering the PORV inoperable; (2) failure to follow procedures when filling the reactor coolant system (RCS) on October 5,1997, that resulted in an uncontrolled spill of water from the control rod drive mechanism (CROM) vents; and (3) Inadequacies in the procedure for the control of radioactive (hot) particles that resulted in a worker receiving a significant skin exposure on October 4,1997.


The most significant violation involved the inoperable PORV. During rewiring of the PORV actuation solenold, following replacement of the PORV during the 11R refueling outage in October,1995, the terminal connections on the solenoid were not clearly marked.

ATTACHMENT RESPONSE TO NOTICES OF VIOLATION January 27,1998, IR 50-289/97-09-02 (EA 97-533)
And February 26,1998, IR 50-289/97-10-01 Notice of Violation 97-09-02 Technical Specification (TS) 6.8.1 requires, in part, that Written procedures be implemented covering the applicable procedures recommended in Appendix 'A' of Regulatory Guide 1.33, Revision 2, February 1978. Regulatory Guide 1.33, Appendix
'A', Section 3.0 recommends, in part, instructions for filling and venting the reactor coolant system (RCS) and for operation of decay heat removal systems.
Operating procedure (OP) 1103-2, " Fill and Vent of the Reactor Coolant System," section 3.1.2, step 17.c, requires, in part, that when the level at the center control rod drive mechanism (CRDM) is observed at one to two feet below the top, terminate the RCS fill and hold level.
OP 1104-4, " Decay Heat Removal System," section II of Enclosure 2, "Make Up to the RCS Directly from the BWST," provides a caution that make up to the RCS directly from the borated water storage tank (BWST) must be carefully monitored since large volumes of water can be transferred very rapidly. Step 1 of section II states, in part, that controlling the level in the RCS using this method is not considered to be, nor should it be, used as a major RCS fill and vent method.
Contrary to the above, on October 15,1997, the licensee failed to properly implement operating procedures 1103-2 and 1104-4 while filling and venting the RCS following a refueling outage. Specifically, while filling the RCS from the reactor coolant bleed tank (RCBT)in accordance with OP 1103-2, make up to the RCS was established directly from the BWST, contrary to the instructions in Enclosure 2 of OP 1104-4. The additional makeup caused a prompt rise in pressurizer level. Even though the operators observed the level increase in the control room terminated the RCS fill from the RCBT, the makeup from the BWST was not immediately terminated due to communications difficulties. Consequently, approximately 50 gallons of RCS water overflowed out of the CRDM vents onto the reactor vessel head area.
GPUN Response:
1. Reasons for Violation GPUN agrees with the violation. In this event, the Shift Supervisor (SS) used poor judgement and inappropriate procedural implementation during the performance of the RCS fill and vent evolution by establishing a flow path from the BWST at a time when it was inappropriate to do so because of the potential for overfill. The SS did not understand Management's expectation that the BWST would not be used for filling the RCS when the pressurizer level was above 100 inches; and, the SS incorrectly assumed that he was filling to 390 inches and thought that he needed much more water than was available in the Reactor Coolant Bleed Tank.

l GPU Nuclear Corporation  2 The failure to perform adequate post maintenance testing following replacement of the pressurizer PORV resulted in this condition not being identified. Specifically, following the incorrect wiring of its actuation solenold, no test was performed to ensure that the PORV l would open in response to en automatic or manual actuation signal. This f ailure corstitutes a violation of the Technical Specification (TS) requirement to perform in service testing. At the conference, you indicated that the failure to perform the post maintenance test (PMT) was due to procedural and work scheduling inadequacles. Specifically, no PMT checkoff was provided in the PORV replacement and inspection procedures, and there was incomotete guidance in the job order package to direct the performance of the PMT.
;
In addition, the evolution was started during a shift turnover, and supervisory methods and verbal communications between team members were less than adequate; also, the use ofimproper communications equipment contributed to a delay in event termination.
 
2. Corrective steps taken and results achieved.
 
a. A revision of OP 1104-4 has been made to provide a more specific warning that addresses the use of the BWST as a fill source to strictly prohibit its use when the pressurizer level is at 100 inches or above. This revision also adds signoff requirements to specific steps within the procedure.
 
b. Management has issued instructions to all crews concerning its expectations with respect to the inappropriateness of performing significant plant evolutions while a i shift turnover is in progress. Management has reemphasized the need for strict procedural compliance as well as the need to have a questioning attitude.
 
c.
 
'
Procedural compliance has been stressed with all crews including the requirements: to have procedures available; to properly signoff procedural steps for significant evolutions; and, when procedures are not available, to obtain the procedure and resolve any questionable issue prior to conduct of the evolution.
 
These Management expectations were documented in an internal memorandum to all departments from the Director of Operations & Maintenance.
 
d. Communication enhancements have been made with the modification of the format for conducting the Operations Department outage shift turnover meeting.
 
This has been accomplished by the inclusion of a final summary " repeat back" by the oncoming Shift Supervisor, prior to concluding the meeting, in order to ensure understanding of direction and intent.


Tne inability to open the PORV would have prevented it from performing its pressure relief function either during power operations or during low temperature conditions during heatup and cooldown. Even though the pressurizer safety valves (the primary pressure relief system),
e. By memo from the Plant Operations Director to all Shift Supervisors and crews l the use of appropriate communications equipment, specifically the M&I phone system, are to be used for significant plant evolutions that require numerous transmissions of detailed information.
were available to provk'e overpressure protection during power operations, and administrative controls were in place to provide low te nperature overpressure protection, the diversity provided by the PORV for these functions was not available for the entire operating cycle, a period of 23 months. Additionally, the PORV would not have been available to provide a bleed path for high pressure injection (HPI) cooling or to depressurize the RCS to establish long term decay heat removal following a steam generator tube rupture. The unavailability of tha PORV for pressure relief or HPI cooling had potential conseqeences in that it resulted, as determined by your own calculations, in a 16% increase in the TM! core damage frequency, if an event occurred needing the PORV to be opened. This was preventable if requirements for post-maintenance testing had been met. Therefore, the violation has been categorized at Severity Level lli in accordance with the " General Statement of Policy and Procedure for 'NRC Enforcement Actions" (Enforcement Policy), NUREG 1600.


In accordance with the Enforcement Policy, a base civil penalty in the amount of $50,000ls considered for the Severity Level lil violation that occurred prior to November 12,1995.
3. Corrective steps to be taken to avoid further violations.


Because your facility has been the subject of escalated enforcement actions within the last 2 years,' the NRC considered whether credit was warranted for / dent //ication and Correct /v6 Act/on in accordance with the civil penalty assessment process in Section VI.B.2 of the Enforcement Policy. Credit was warranted for identification because your staff identified, during the 12R refueling outage, that the PORV had been miswired and that nc PMT had been performed following the 11R refueling outage. Credit was also warranted for corrective actions because your actions were considered both prompt and compruhensive. Those actions included: (1) communication of management expectations for self-checking, independent verification, and performance of post maintenance testing; (2) planned revisions to the PORV maintenance procedure to clarify the FMT reqWrements, and to the job order program to include the vendor manual wiring diagrams in the job order package; (3) review of other work packages to ensure that all required PMTs had been performed; and (4) plans to perform a process study to ivify and correct weaknesses in the PMT program, e.g., A Notice of Violation and Pmposed Imposition of Civil Penalties in the amount of $210,000 was issued on October 8.1997 (EAs 97 070. 97117,9,'-t27. and 97 256), for numerous violations related to several areas of plant performance includicg engineering design controls, classification and environmental qualification of components, corrective actions, and emergency preparedness.
.
a. The listing of significant evolutions requiring specific procedures for implementation identified in AP-100lG, " Procedure Utilization," will be expanded to meet Management's expectations informally communicated by the Director of Operations and Maintenance via internal memorandum dated March j 3,1998. This expansion of AP-100lG will increase the number of evolutions that ;
require having a procedure in-hand when performing the evolution. l b. To achieve a higher standard of administrative controls, GPUN intends to make i programmatic improvements to strengthen procedural compliance and l documentation. A self-assessment and benchmarking review of procedural l
        '
controls and usage at TMI will be conducted, considering industry good practices and guidance. The implementation of any requisite improvements in procedural controls / usage resulting therefrom will be instituted by changes to atTected i
        '
procedures.

GPU Nuclear Corporation 3 Therefore, to encourage prompt identification and comprehensive correction of violations, I have been authorized, after consultation with the Director, Office of Enforcement, not to propose a civil penalty in this case. However, significant violations in the future could result in a civil permity.

4. Dates of full como~liance.
 
Full compliance has been achieved Corrective action 3.a will be completed by June 30,1998. Corrective action 3.b (1) will
, be completed by September 30,1998; and, the schedule for implementation of the requisite procedure changes 3.b.(2) will be developed by October 31,1998. i I

Notice of Violation 97-10-01    ,
Technical Specifications 6.5.1.1, " Technical Review and Control," and 6.8.2,
" Procedures and Programs," require, in part, that any substantive changes, including the '
change ofintent to procedures that affect nuclear safety, shall be reviewed and approved prior to implementation.
 
Contrary to the above, on November 20,1997, GPUN did not review and approve a substantive change to an existing inservice test (IST) surveillance procedure 1300-3K,
"IST of Reactor River Water Pumps and Valves," before the closure of the reactor building emergency cooler inlet and outlet valves to conduct a leak test. The IST procedure was written and approved to determine the cooler inlet and outlet valve open and closed times, but did not allow the valves to be closed for the seven hour leak test.
 
GPUN Response:
1. Reasons for Violation GPUN concurs there was a violation of Technical Specification 6.5.1.1 and 6.8.2.
 
However, for accuracy it should be noted that on November 20,1997 the Operators did not rely upon use of the Sun >eillance Procedure 1300-3K to conduct the investigation of leakage from the Nuclear Services system. This trouble shooting activity was performed using the guidance of AP-1029 and OP-100lG. On November 24,1998 the Operators did use SP-1300-3K for guidance to conduct valve cycling as allowed by OP-1001J,
" Tech. Spec. Surveillance Program Testing," which states: "where the intent of a test is other than to satisfy a TS surveillance testing requirement, the appropriate TS surveillance procedure may be used for instructional guidance and as a vehicle to document performance."


With respect to the overfill of the RCS, the shift supervlsor (6S), who was supervising the fill and vent of the 11CS in October,1997, believed that there was not enough water available in the reactor coolant bleed tank (RCBT) to complete the intended evolution. Although the SS appropriately consulted his supervisor and was told that there was sufficient water available in the RCBT, the SS, still believing that there was insufficient water available, used an inappropriate procedure to fill the RCS from the borated water storage tank (BWST). Other control room operators did not que#on the SS's decision. Your staff failed to adhere to the limitations provided in the decay heat removal (DHR) system operating procedure (OP) when they used the DHR pumps to provide makeup to the RCS directly from the BWST during the fill and vent of the RCS, Additionally, they failed to follow the RCS fill and vent procedure when they failed to terminate the RCS fill at the required point.-- As a result, borated water -
Nevertheless, GPUN has determined that on November 20,1998 the requirements of procedures AP-1029," Conduct of Operations," and OP-100lG," Procedure Utilization,"
spilled onto the reactor vowsel head and control rod drive (CRD) components, potentially degrading those components and creating a radiclogical condition warranting remediation.
were not met, in that the crew's determination that there would be no adverse affects on the operability of the RR system due to closing of the RR-V-3s was not logged. Prior to closing the valves the crew did discuss and determine that there would be no adverse affects on operability because an ES signal would cause the valves to open in the event of a LOCA, if the valves were closed. However, the procedurally required logging of this determination did not take place.


While this violation is classified at Severity Level IV given the significance of the occurrence, it raises concerns regarding the questioning attitude of the staff and management's expectations for adherence to procedures. At the aonference, you indicated that the problem was that the SS failed to comply with normal work practices specified in your conclect of ciperations administrative procedure (AP), rather than's failure to adhere to the RCS fill and vent procedure or the DHR system operating procedure. The NRC is concerned that plant

Finally, with respect to the inadequate hot particle control procedure, an emergent hot particle *

area was discovered during surveys of newly exposed surfaces upon raising the reactor vessel heed seal plate following work in the fuel transfer canal in October,1997. Upon discovery of these conditions, the radiation control technician (RCT) assigned to the job elected to proceed without consulting supervision. Although the area was subsequently decontaminated, the surveys that were performed f*>llowing the decontamination were not adequate to verify the removal of the hot particles. Additionally, a hot particle control area was not formally established. Your radiological protection (RP) procedure RP for hot particle controls was inconsistent with 10 CFR 20.1501 in that it did not provide sufficient direction to assure that adequate surveys were performed and that adequate hot particle controls were established.
-
,
 
'
,
l GPUN has also determined that AP-1029 currently does not contain adequate guidance l and controls for the conduct of trouble-shooting activities. It is Management's expectation that evolutions of this nature would be controlled by means of a trouble shooting plan based on appropriate guidance using a graded approach and/or by a Special Temporary Procedure (STP). The STP process is designed to assure that proper precautions are established, and that reviews of design basis requirements and other safety considerations are conducted prior to executing the STP. l In addition, a contributing cause for not initiating a STP for this plant evolution was the l failure to effectively translate a change in design basis assumptions into operating procedures (n.b., the necessity for the assumption was later negated by reanalysis).


- This constituted a violation of Technical Sp cification requirements for the radiation protection
Specifically, the initial assumption made was that an overpressure on the Reactor Building Emergency Coolers needed to be maintained in order to address GL 96-06  ,
concerns. This assumption was not identified by the System Performance Team (SPT) l for consideration of potential impact upon operating procedures when the SPT performed !

program which require that procedures for personnel radiation protection shall be prepared consistent with the requirements _of -10 CFR 20. As a result of the inadequate surveys and lack of sufficient hot particle controla, a worker received a calculated dose of approximately 14 rem to the skin. While the violation is classified at Severity Level IV, the NRC :s concemed that, when it was determined that hot particles were present, an evaluation, to determine the

I 2. Corrective stens taken and results achieved.
t GPU Nuoleer Corporation  4 an appropriate interval for personnel frisking for hot partici t9 was not established. Without l
 
these controls, there was a potentiel for skin exposures even more significant than the exposure that cccurred.
a. Management has re-emphasized its expectations that crews are to comply with the requirements for obtaining permission and logging all work related to the performance of evolutions not covered by written procedures, and to be aware of ,
the administrative requirements and in particular the documentation requirements j stipulad in AP-1029. i
      :
3. Corrective steps to be taken to avoid further violations.


With respect to the apparent violation involving the failure to follow procedures for the once-through cteam generator (OTSG) locked high radiation area that was discussed at the conference, the NRC concluded that the wutker that left the OTSG manway area unattended with the high radiation area door unlocked failed to adhere to the requirements of your locked high radiation area AP. However, based on the information provide j at the conference and during subsequer't telephone conversations with Mr. Etheridge of your staff, the NRC concluded that the potential for inadvertent entry into the high radiation area was low. The manway opening was continuously monitored at a remote location with a video camera and the individual monitoring the opening by camera was in direct communication with personnel in the close proximity of the unlocked manwsy. Therefore, because it was licensee identified; was correct 6J immediately; and was not ropetitive within the last two years, the violation of the locked hig5 radiation area AP will not be cited in accordance with Section Vll.B.1 of the Enforcement Policy.
a. GPUN will develop new/ revised guidance to effectively strengthen work controls l relevant to the conduct of trouble shooting within AP-1029," Conduct of i Operations." The guidance on trouble shooting considerations will address more
      '
formally, Management's expectations as previously outlined in an internal memoran.fum dated March 3,1998, from the Director of Operations and Maintenance, and will be based on a graded approach for the use of a trouble shooting plan and/or an STP.


You are requirnd to respoad to this istter and should follow the instructions specified in the enclosed Notice when preparing your response. The NRC will use your response, in part, to determine whether further enforcement action is necSwary to ensure compliance with regulatory requirements, in accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter, its enclosure, and your response will be placed in the NRC Public Docurr.ent Room (PDR).
b. This event will be incorporated into the operating experience presentations for Licensed Operator training and requalification, as well as, in the Engineering Support Personnel training. The event review will emphasize how the change control processes should provide identification of the relationship between the design basis assumptions and the operational requirements for plant systems.

Dear Sir:

Subject: Three Mile Island Nuclear Station, Unit 1, (TMI-1)

Operating License No. DPR-50 Docket No. 50-289 Response to Notices of Violation (NOV) 97-09-02, dated January 27,1998 And NOV 97-10-01, dated February 26,1998 The attachment to this letter transmits the GPU Nuclear (GPUN) Inc. responses to the NOVs referenced above. Each violation identified in the NOVs is addressed separately to include: (1)

the reason for the violation; (2) corrective actions taken and results achieved; (3) corrective actions to be taken, if applicable, to avoid future violations; and (4) the dates of full compliance achievement. The public health and safety were not affected by these events.

The two violations involved procedural non-compliance and usage issues. While we determined that the root causes for each event were different, we have concluded that programmatic improvements should be considered in addition to the specific actions identified in this response.

We plan to expand the list of applicable procedures required by administrative controls to be carried and signed off during performance of plant evolutions by June 30,1998. We also plan to conduct a self-assessment and benchmarking review of the procedural controls currently in place. The review will consider industry guidance and good practices employed by other nuclear plants to determine what changes should be made to improve procedure control or usage at TMI.

The target date for completion of this review is September 30,1998. A schedule for the development and implementation of requisite improvements is expected to be in place by October 31,1998.

ATTACHMENT RESPONSE TO NOTICES OF VIOLATION January 27,1998, IR 50-289/97-09-02 (EA 97-533)

And February 26,1998, IR 50-289/97-10-01 Notice of Violation 97-09-02 Technical Specification (TS) 6.8.1 requires, in part, that Written procedures be implemented covering the applicable procedures recommended in Appendix 'A' of Regulatory Guide 1.33, Revision 2, February 1978. Regulatory Guide 1.33, Appendix

'A', Section 3.0 recommends, in part, instructions for filling and venting the reactor coolant system (RCS) and for operation of decay heat removal systems.

Operating procedure (OP) 1103-2, " Fill and Vent of the Reactor Coolant System," section 3.1.2, step 17.c, requires, in part, that when the level at the center control rod drive mechanism (CRDM) is observed at one to two feet below the top, terminate the RCS fill and hold level.

OP 1104-4, " Decay Heat Removal System," section II of Enclosure 2, "Make Up to the RCS Directly from the BWST," provides a caution that make up to the RCS directly from the borated water storage tank (BWST) must be carefully monitored since large volumes of water can be transferred very rapidly. Step 1 of section II states, in part, that controlling the level in the RCS using this method is not considered to be, nor should it be, used as a major RCS fill and vent method.

Contrary to the above, on October 15,1997, the licensee failed to properly implement operating procedures 1103-2 and 1104-4 while filling and venting the RCS following a refueling outage. Specifically, while filling the RCS from the reactor coolant bleed tank (RCBT)in accordance with OP 1103-2, make up to the RCS was established directly from the BWST, contrary to the instructions in Enclosure 2 of OP 1104-4. The additional makeup caused a prompt rise in pressurizer level. Even though the operators observed the level increase in the control room terminated the RCS fill from the RCBT, the makeup from the BWST was not immediately terminated due to communications difficulties. Consequently, approximately 50 gallons of RCS water overflowed out of the CRDM vents onto the reactor vessel head area.

GPUN Response:

1. Reasons for Violation GPUN agrees with the violation. In this event, the Shift Supervisor (SS) used poor judgement and inappropriate procedural implementation during the performance of the RCS fill and vent evolution by establishing a flow path from the BWST at a time when it was inappropriate to do so because of the potential for overfill. The SS did not understand Management's expectation that the BWST would not be used for filling the RCS when the pressurizer level was above 100 inches; and, the SS incorrectly assumed that he was filling to 390 inches and thought that he needed much more water than was available in the Reactor Coolant Bleed Tank.

-

In addition, the evolution was started during a shift turnover, and supervisory methods and verbal communications between team members were less than adequate; also, the use ofimproper communications equipment contributed to a delay in event termination.

2. Corrective steps taken and results achieved.

a. A revision of OP 1104-4 has been made to provide a more specific warning that addresses the use of the BWST as a fill source to strictly prohibit its use when the pressurizer level is at 100 inches or above. This revision also adds signoff requirements to specific steps within the procedure.

b. Management has issued instructions to all crews concerning its expectations with respect to the inappropriateness of performing significant plant evolutions while a i shift turnover is in progress. Management has reemphasized the need for strict procedural compliance as well as the need to have a questioning attitude.

c.

'

Procedural compliance has been stressed with all crews including the requirements: to have procedures available; to properly signoff procedural steps for significant evolutions; and, when procedures are not available, to obtain the procedure and resolve any questionable issue prior to conduct of the evolution.

These Management expectations were documented in an internal memorandum to all departments from the Director of Operations & Maintenance.

d. Communication enhancements have been made with the modification of the format for conducting the Operations Department outage shift turnover meeting.

This has been accomplished by the inclusion of a final summary " repeat back" by the oncoming Shift Supervisor, prior to concluding the meeting, in order to ensure understanding of direction and intent.

e. By memo from the Plant Operations Director to all Shift Supervisors and crews l the use of appropriate communications equipment, specifically the M&I phone system, are to be used for significant plant evolutions that require numerous transmissions of detailed information.

3. Corrective steps to be taken to avoid further violations.

.

a. The listing of significant evolutions requiring specific procedures for implementation identified in AP-100lG, " Procedure Utilization," will be expanded to meet Management's expectations informally communicated by the Director of Operations and Maintenance via internal memorandum dated March j 3,1998. This expansion of AP-100lG will increase the number of evolutions that ;

require having a procedure in-hand when performing the evolution. l b. To achieve a higher standard of administrative controls, GPUN intends to make i programmatic improvements to strengthen procedural compliance and l documentation. A self-assessment and benchmarking review of procedural l

'

controls and usage at TMI will be conducted, considering industry good practices and guidance. The implementation of any requisite improvements in procedural controls / usage resulting therefrom will be instituted by changes to atTected i

'

procedures.

.

?

4. Dates of full como~liance.

Full compliance has been achieved Corrective action 3.a will be completed by June 30,1998. Corrective action 3.b (1) will

, be completed by September 30,1998; and, the schedule for implementation of the requisite procedure changes 3.b.(2) will be developed by October 31,1998. i I

.

Notice of Violation 97-10-01 ,

Technical Specifications 6.5.1.1, " Technical Review and Control," and 6.8.2,

" Procedures and Programs," require, in part, that any substantive changes, including the '

change ofintent to procedures that affect nuclear safety, shall be reviewed and approved prior to implementation.

Contrary to the above, on November 20,1997, GPUN did not review and approve a substantive change to an existing inservice test (IST) surveillance procedure 1300-3K,

"IST of Reactor River Water Pumps and Valves," before the closure of the reactor building emergency cooler inlet and outlet valves to conduct a leak test. The IST procedure was written and approved to determine the cooler inlet and outlet valve open and closed times, but did not allow the valves to be closed for the seven hour leak test.

GPUN Response:

1. Reasons for Violation GPUN concurs there was a violation of Technical Specification 6.5.1.1 and 6.8.2.

However, for accuracy it should be noted that on November 20,1997 the Operators did not rely upon use of the Sun >eillance Procedure 1300-3K to conduct the investigation of leakage from the Nuclear Services system. This trouble shooting activity was performed using the guidance of AP-1029 and OP-100lG. On November 24,1998 the Operators did use SP-1300-3K for guidance to conduct valve cycling as allowed by OP-1001J,

" Tech. Spec. Surveillance Program Testing," which states: "where the intent of a test is other than to satisfy a TS surveillance testing requirement, the appropriate TS surveillance procedure may be used for instructional guidance and as a vehicle to document performance."

Nevertheless, GPUN has determined that on November 20,1998 the requirements of procedures AP-1029," Conduct of Operations," and OP-100lG," Procedure Utilization,"

were not met, in that the crew's determination that there would be no adverse affects on the operability of the RR system due to closing of the RR-V-3s was not logged. Prior to closing the valves the crew did discuss and determine that there would be no adverse affects on operability because an ES signal would cause the valves to open in the event of a LOCA, if the valves were closed. However, the procedurally required logging of this determination did not take place.

,

l GPUN has also determined that AP-1029 currently does not contain adequate guidance l and controls for the conduct of trouble-shooting activities. It is Management's expectation that evolutions of this nature would be controlled by means of a trouble shooting plan based on appropriate guidance using a graded approach and/or by a Special Temporary Procedure (STP). The STP process is designed to assure that proper precautions are established, and that reviews of design basis requirements and other safety considerations are conducted prior to executing the STP. l In addition, a contributing cause for not initiating a STP for this plant evolution was the l failure to effectively translate a change in design basis assumptions into operating procedures (n.b., the necessity for the assumption was later negated by reanalysis).

Specifically, the initial assumption made was that an overpressure on the Reactor Building Emergency Coolers needed to be maintained in order to address GL 96-06 ,

concerns. This assumption was not identified by the System Performance Team (SPT) l for consideration of potential impact upon operating procedures when the SPT performed !

-

the analyses prepared for the original Generic Letter response.

I 2. Corrective stens taken and results achieved.

a. Management has re-emphasized its expectations that crews are to comply with the requirements for obtaining permission and logging all work related to the performance of evolutions not covered by written procedures, and to be aware of ,

the administrative requirements and in particular the documentation requirements j stipulad in AP-1029. i

3. Corrective steps to be taken to avoid further violations.

a. GPUN will develop new/ revised guidance to effectively strengthen work controls l relevant to the conduct of trouble shooting within AP-1029," Conduct of i Operations." The guidance on trouble shooting considerations will address more

'

formally, Management's expectations as previously outlined in an internal memoran.fum dated March 3,1998, from the Director of Operations and Maintenance, and will be based on a graded approach for the use of a trouble shooting plan and/or an STP.

b. This event will be incorporated into the operating experience presentations for Licensed Operator training and requalification, as well as, in the Engineering Support Personnel training. The event review will emphasize how the change control processes should provide identification of the relationship between the design basis assumptions and the operational requirements for plant systems.

c. A self-assessment and benchmarking review of procedural usage as described in Corrective Action 3.a for the response to NOV 97-09-02 above will be conducted.

d. The System Performance Teams (SPTs) are accountable for ensuring that changes made in design assumptions, as related to Operations or Maintenance activities are thoroughly evaluated and, when needed, incorporated into plant procedures, training, and design documents. The SPTs minimum membership includes representatives from Operations, Maintenance, and Engineerin ,e departments.

GPUN will review this specific event with the System Engineers, who are the J

.

SPT leaders. The review will emphasize how the change review process could have provided identification of the relationship between the design basis assumptions and the operational reqqirements for the system. Additional .

' guidance will .be incorporated into the next revision to the System Engineering Guideline (Document #990-2471) to capture the lessons learned from this event.

- The SPT and System Engineer review goes above and beyond the existing 10CFR50.59 review requirements as provided by the GPUN Safety Review Processes that are required for plant modifications and/or procedure changes.

!

4. Dates of full comoliance:

Full compliance has been achieved.

Corrective actions 3.a and 3.b to avoid future violations related to this NOV will be completed by December 31,1998. Corrective action 3.c will be completed as identified above under corrective action 3.b for NOV 97-09-02, in two parts, namely: the self-assessment study is scheduled for September 30,1998 and its implementation schedule for October 31,1998. Corrective action 3.d will be achieved by June 30,1998.
