Temporary Modifi ca ti ons i

Technical Specification 6.8.1 requires that written procedures be

established, implemented, and maintained covering the activities

recommended in Appendix A of Regulatory Guide 1.33. Revision 2.

February 1978.

Procedure OPGP03-ZO-0003. Revision 7. dated September 12. 1987

"Temporary Modifications and Alterations." has been established in

accordance with this Technical Specification.

,

8

Section 4.7 of this procedure requires that the control room hard copy of

piping and instrumentation drawings affected by a temporary modification

I be annotated and clouded in red to identify the existence of a temporary

modification. It further requires that a copy of the temporary

modification request be attached to the drawing and a notation of which

' drawings were updated to be made on the original of the temporary

modification request.

. met f or Temporary Modification TI-EV-87-252 f or Drawing 5R289F05038 in

that no markup had been made.

i

<

j Reason for violationt

'

The root cause of this violation was the Systems Engineer's lack of

attention to detail in following the procedure. A contributing factor

was a lack of positive controls (e.g., signature verifications) on the 1

Temporary Modification Request (THR) form to ensure compliance with the

l

procedure. Another contributing factor was a lack of clarity in the . '

C. Statement of Violatior 8801-03:

Locked Valves

Technical Specification 6.8.1 requires that written procedures be

established, implemented, and maintained covering the activities

recommended in Appendix A of gegulatory Guide 1.33. Revision 2.

February 1978. Section 3 of this appendix recommends procedures for

operation of the emergency core cooling system.

Procedure 1 POP 02-SI-0002. Revision 6. dated December 30, 1987 "Safety

Injection System Initial Lineup." has been established in accordance with

this Technical Specification.

Form 9 of this procedure. Initial Lineup Train C. requires Manual Valves

SI-0059C. SI-0224C. ar.d SI-0070C to be locked closed.

Contrary to the above on January 6. 1988, the NRC inspectors found that

SI-0059C was closed, but not locted and that SI-0224C and SI-0070C were

closed but inadequately locked. The cables and padlocks on these latter

two valves could easily be removed by hand.

Reason for violation:

The root cause of the violation was lack of attention to detail on the

part of operations personnel who inspect valves in accordance with the

Locked Valve Program in that inadequately locked and/or unlocked valves

were not identified and corrected in accordance with the Locked Valve

Program OPGP03-20-0027.

Corrective actions that have been taken:

1. Valves SI-0070C and SI-0224C were locked and valve SI-0059C was

tagged as allowed by procedure.

2. valves required to be locked in accordance with the Locked Valve

Program were inspected for proper position and locking devices or

administrative controls. None were found to be improperly

positioned. Those that were found to be inadequately locked were

either properly locked or administrative controls were implemented

through the station clearance process.

Corrective actions which will be taken

No further action is required.

Full Compliance

.

The plant is in full compliance.

D. Statement of Violation 8801-04:

Containment Intecrity

,

Technical Specification 3.6.1.1 requires that containment integrity be .

maintained in Modes 1. 2. 3. and 4. The conditions of license

regulation. 10CTR50.54 invokes Appendix J to 10 CTR 50 to define

containment integrity and to limit combined leakage measured by test, to

less than 0.6 La.

Contrary to the above the licensee was in Mode 4 on October 31 and

Fovember 1. 1987. With Containment Isolation Valve BIRAMOV0003. not

tested for local leak rate after maintenance so that the ability to moet

the 0.6 La criterion was not determined.

Reason for violation:

The root causes of the event were determined to be:

1. Failure to provide maintenance planners and maintenance supervisors

with adequate training concerning post maintenance testing (PMT)

requirements regarding containment integrity.

2. Failure to identify the appropriate PMT requirements f or local leak

rate testing on the MVR during supervisory review.

Corrective actions that have been taken:

1. A Local Leak Rate Test was satisf actorily performed on the subject

valve and it was returned to an operable status at approximately 2200

hours on January 6. 1988.

2. A review c,' MVRs and LLRT records was conducted to ensure that proper

testing had been done to assure containment integrity.

3. Informatica regarding this event was discussed with maintenance

supervisory personnel and maintenance planners. The intent of these

briefinjs was to make these personnel aware of the importance of

maintaining containment integrity. Maintenance planners were advised

to discuss PMT requirements with the cognizant system engineer prior

to issuang a MWR. especially in regards to containment isolation

valves.

4. To enhance the current MVR program. NWR procedure. OPGP03-ZM-0003.

was revised to assure that the required PMTs are identified on MVRs

involving containment isolation valves.

E. Statement of Violation 8801-05:

Surveillance Procedure Discrepancies

Criterion V of 10 CTR 50. Appendix B. requires, in part, that activities

'

'affecting quality be performed in accordance with approved drawings,

insttuctions, and procedures appropriate to the activity.

The licensee's approved Operations Quality Assurance Plan. Section 112.

"Test Control." Paragraph 6.4 requires that test procedure shall provide

instructions for performing tests and provisions for documenting results.

Contrary to the above, the licensee failed to follow procedures

associated with the Surveillance Program and/or failed tp provide

adequate procedure to control the activities affecting the quality of

Technical Specification surveillance as identified in the six examples

cited below: ,

.

1. In December 1987 the licensee collected 250 milliliter waste liquid i

"

discharge samples in lieu of the one liter samples required by

Procedure 1 PSP 07-WL-0001.

2. On January 7. 1988, it was f ound that Procedure OPSP07-CR-0002 was (

inadequate in that it failed to provide the necessary requirement to

calculate an average sample. Chemistry Technicians were observed to

be calculating the average sample in accordance with verbal

instructions in lieu of following the procedure.

3. On January 6. 1988, it was found the Procedures 1 PSP 02-RC-0454. 0461.

and 0462 had been improperly modified by Field Change Request to

waive Stegs 7.4.2 and 7.7.16 when reactor coolant temperature is

below 538 F in that the data sheet was not modified to support the

change. ;

4. On January 7, 1988, it was found that Procedure OPSPO4-XC-0001

Revision 1. had been improperly revised such that changes were

incorporated into an unapproved draf t of Revision 0 in lieu of an

approved copy of Revision O. resulting in a Revision 1 that contained

j draft errors. This is contrary to the requirements of

OPGP03-ZA-0002. Revision 10. "Plant Procedures."

5. On January 6 1988, it was found that Procedure 1 PSP 11-RH-0004

Revision 1. failed to contain numeric values of the acceptance

criteria due to a series _of inappropriate char.ges. This is contrary

to the requirements of OPGP03-ZE-0005. Revision 6. "Plant

Surveillance Procedure Preparation." Section 3.2.6.

.

l 6. On January 6 1988, it was found that two completed surveillance test

packages for OPSPO4-DG-0001 were presented to the Plant Operations

Review Committee (PORC) for acceptance of the results based on ,

previously accomplished preoperational test information with missing ,

data. 7he packages were approved by the PORC with missing data.

Reason for violationt !

l

Item I was attributable to poor judgement by technicians who decided to

!

substitute a different size container for the size specified in the

procedure.

'

r

Item 2 was attributable to inadequate description rf required

calculations in the procedure.

Items 3. 4. and $ were attributable to a f ailure to follow procedures

regarding the use of FCRs.

,

Item 6 is attributable to two factorst

1. Personnel reviewing the pre-operational test package prior to its

presentation to PORC failed to detect a copying error.

2. The level of review performed by PORC vas not of sufficient detail

and depth to detect the copying error.

Corrective actions that have been takent

Item 1: Chemical Analysis personnel have been reinstructed regarding

I

the importance of f ollowing procedures verbatim.

Item 2: Chemical Analysis surveillance procedures requiring

calculations have been reviewed and revised as necessary to

ensure that adequate instruction on performance of the

calculations is provided.

Items 3-5 A Departmental bulletin was issued providing additional

guidance to NPOD personnel regarding the control of Field

Change Request changes to surveillance procedures.

I

Procedure OPGPO3-ZA-OOO2 "Plant _ Procedures" was revised to

include specific guidelines for the review and implementation

of Field Change Requests.

Item 6: The data missing from the subject packages was reviewed and

approved by PORC and inserted in the file packages,

t

An ISEG special investigation was conducted to review the PORC

process to recommend possible enhancemente. The

recommendations, which wele issued February 22. 1988 include

more formal control of the PORC meetings, more control of

"walk-on" items, better definition of s: ope of review.

F. Statement of Violation 8801-06:

Implementation of Technical Specification Eeauirements

Technical Specification 6.8.1 requires that written procedures shall be . 1

,

established, implemented, and maintained covering activities recommended ;

in Appendix A of Regulatory Guide 1.33. Revision 2. February 1978.

'

Contrary to the above, it was found on January 7.1988, that the licensee

had failed to provide test procedures, which completely implemerted the

final technical specifications as cited below:

1. Procedure 1 PSP 10-RC-0001. Revision 0, contained an acceptance

criterion calling for a figure in the technical specifications which

had been deleted when the final technical specifications were issued.

thus resulting in an incomplete and inadequate procedure for

conducting the surveillance. l

.

I

2. Procedure OPSP10-II-0003 was found to contain an incorrect and

nonconservative equation for adjusting the core radial peaking factor [

limit f or f ractional power levels, thus resulting in an incorrect and

inadequate procedure conducting the surveillance. !

Reason for violations f

The root cause of this violation was that the process to incorporate

changes in the T9chnical Specifications into procedures did not track I

required actions to completion. t

Corrective actions that have been takent .

i

1. OPSP10-II-0003 has been corrected to be consistent with the .4chnical ;

,

Specifications. Procedure 1 PEPO 4-ZG-0007 has been identified as the '

proper procedure for use in RCS flow measurement in lieu of

IPSP10-RC-0001. I

2. Suf ficient review of surveillance procedures has been completed to

assure compliance with Technical Spec 2fication requirements for

operation through Mode 2.

3. Procedure OPGP03-ZA-0002 has been revised to require an independent

techn* cal review of new procedures. Requirements have beeb added to

the procedure to perform a "walk through" of new surveillence

procedures to confirm the Frecedure can be accomplished as written.

Additional procedure review criteria have been imposed by means of an

uttribute check sheet which includes items for confirming Technical

.

Specification requirements.

.

4. Interdepartmental procedure 3.20Q is now in ef f ect which requires

Technical Specification changes to be tracked f rom request through

implementation. It also requires a QA verification of implementation.

1- Reason for the violationt

U

The root cause of the violation was inadequate assignment of resources to

prioritize and resolve the SPRs.

.

Corrective actions that have been taken I

.

o

1. The safety significance of each SPR is evaluated when the SPR is

I first initiated, and immediate action is taken if required to assure

plant safety. A review was performed which confirmed that the

l

conditions described in the open SPRs have been adequately addressed

' so that plant saf ety is not adversely af fected.

2. Revision 1 of Procedure 1.450 was implemented on February 22, 1988. !

This new procedure increased management's involvement in the process

by requiring an early establishment of priority and due date by the

'

Plant Manager. The revision also requires the SPR originator to take

the SPR directly to the Shif t Supervisor.

3. . Additional licensing engineers have been assigned to coordinate

resolution of SPRs. These personnel have participated in a concerted

i

effort to resolve overdue SPRs. The backlog of overdue SPRs has been

reduced to an acceptable level.

H. Inadecuate corrective Action (8801-08):

' Criterion XVI of Appendix B to 10 CFR Part 50 and the licensee's approved

quality assurance plan require conditions adverse to quality be proeptly I

identified and corrected. In August 1987, a quality assurance audit

[

deficiency' report was issued wh4ch identified 55 of 179 station problem

reports were overdue for completion. The deficiency was closed on the

basis that tracking responsibility for station problem report ,

investigation tracking was procedurally changed.

Contrary to the above, it was found on January 4, 1986, that the

corrective action was not adequate in that 68 of 204 station problem

,

reports were overdue for completion.

Reason for the violation:

As noted in the statement of the violation, the backlog of overdue SPRs

was identified in an audit in August 1987, and as corrective action

procedures were changed to assign responsibility for coordination of SPRs

to Licensing. Nuclear Assurance accepted this response and a follow up

audit to determine the effectiveness of the corrective action was

scheduled for February 1988. Prior to the follow-up audit, management

failed to identify that the corrective action had not been effective.

Corrective actions which have been taken:

.

In accordance with the schedule adopted upon acceptance of the response

to the August 1987 audit, in February 1988 Nuclear Assurance completed

its follow-up audit of the effectiveness of the ccrrective actions. The

,

follow-up audit identified inadequate effectivenesr, of the earlier

corrective action as a significant deficiency (DR S87-064. Rev.1).

l

J

Response to DR 587-064. Rev. 1 is due by March 18. 1988. The response to

! DR S87-064. Rev. I will be reviewed by Nuclear Assurance.

The corrective actions described in response to Notice of Violation

88 01-07 have been implemented. and are expected to resolve DR S87-064.

,

l

Rev. 1. As an interim measure, until management gains added confidence

in the effectiveness of the revisions to the SPR program. Licensing is

providing management with weekly reports of SPR status.

Corrective actions that will be taken:

As a result of the DR. a review of Station Problem Reports is being

conducted to assure that root causes were adequately addressed and that

supporting documentation properly dispositions the required actions.

This activity is expected to be complete by 60 days after the issuance of i

.

the Full Power operating License.

.

Full Compliance:

The plant will be confirmed to be f ull compliance utan completion of the

SPR review described above. ,
