4.1.3 Work Requests (WR) may be generated by anyone working at CPSES. WRs shall'be initiated either on the VR form or by 8
direct entry into the MMCP. A Work Order number will be assigned upon entry of the WR into the KMCP.
NOTE:
The preprinted number on the WR form or the WO number generated by the MMCP can be used to track the request.
4.1.4 The originator should hang the VR tag (card stock copy of i
the VR) on the item whenever possible.
NOTE:
Eanging the WR tag on the item aids in locating the itee for problem verification and maintenance. WR tags should not be hung on control boards or whenever it would interfere with component operation or increase personnel exposure.

NRC FINDINGS i NRC FINDING NEO 3.05 contains wording that appears in variance with Criterion XV by adding the phrase "...and cannot be corrected within the scope of such requirements or otherwise [ sic] requires an Engineering disposition" to the applicability statement. This appears to mean if it can be fixed by some means, it is not nonconforming and does not need to be reported as nonconforming.
RESPONSE
NEO 3.05, " Reporting and Control of Nonconformances", paragraph 2.1 J states "This procedure is applicable to quality related items or conditions which deviate from drawings, specifications, or other engineering requirements and cannot be corrected within the scope of such requirements or otherwise requires an Engineering disposition." The wording in paragraph 2.1 means that any nonconforming condition which is dispositioned " repair", or "use-as-is", which by definition requires Engineering approval, must be accomplished in accordance with NEO 3.05 by using a Nonconformance Report. Items which can be corrected within-the scope of existing engineering requirements and require no Engineering input (i.e., " rework" or " scrap") may be corrected in accordance with that organization implementing procedures. In the case of Operations this means the Work Request / Work Order Program. l 1 a 6
NRC FINDING A note contained in Section 6.0 of NEO 3.05 states, "Nonconformance Reports shall be prepared on items when a ' repair' or 'use-as-is'- disposition is required." The meaning here appears to be that the ' type of disposition is the judging factor for writing Nonconforrnance Reports (NCR's), not that a nonconforming condition exists.
RESPONSE
The fact that an item does not meet specified requirements is the criterion used to determine an item is nonconforming. An NCR is required for nonconforming conditions requiring a " repair" or "use-as-is" disposition. If the item can be reworked, a Work Request / Work Order is written to%.e.r J identify and correct the nonconforming condition. a $'f,' wpnero 7
t: NRC FINDING Section.6.4 of NEO 3.05 starts with a sentence that reads, "Upon discovery. L of a nonconforming condition, it should be ' determined if an NCR is required." This again relates to the above note for detennining _ NCR requirements by the type of disposition.
RESPONSE
NEO 3.05, " Reporting and Control of Nonconformances", paragraph' 6.4 6 states. ir.. part, "Upon discovery of a nonconforming condition it should be determined if an NCR.is required. Work documents or NCR's shall be prepared to correct the nonconformance by rework or replacement. If the item cannot be reworked or replaced a Nonconformance Report shall always be originated." This paragraph clearly establishes and acknowledges that a ~ nonconforming condition exists. The question remaining is, can it be reworked, repaired, or used as is. If it can be reworked, then a work document such as the Work Request / Work Order can be used. If not, then an NCR.must be written to get Engineering approval of the " repair" or use-a's-is" and dispositioned. 8
c. l h [. NRC FINDING Section 6.5 of NEO 3.05 tasks QA/QC to perform an evaluation of NCR's. . The evaluation is to " determine if the NCR is valid, complete, and sufficiently. detailed so - the problem. can be clearly understood and i located." The steps following this section provide no guidance for determining validity. Discussion with a representative' of the applicant's l QA/QC department indicated that if an NCR could be written up on a Work Request, the QA/QC evaluator would invalidate the NCR. However, once the NCR has been invalidated and returned to the initiator, there is no explicit procedural instruction requiring the initiator to write up a Work Request.
RESPONSE
The validity review performed by Quality Assurance is for two reasons. First, to assure that a nonconforming conditions exists, and second to assure that items which can be reworked are reported using the Work Request / Work Order. Clear guidance does exist in STA-405' for direction as to what must be done once as is discovered. Paragraph 4.2.2.1 of STA-405 states: mm impman,. "The reporting of nonconformances that are on installed plant equipment shall normally begin with the initiation of a work request and work order, and notification of the Shift Supervisor." l { l 9 l
1 ) i i NRC FINDING Implementing Procedure STA-405, " Control of Nonconforming Materials". states that those identified nonconforming conditions that can be dispositioned by " rework" or " scrap" (i.e. replace) need not be reported on nonconformance reports. Again, as in NEO 3.05, it appears that, the criteria for writing NCR's is the method of disposition, not the fact that an 3 item is nonconforming. Additionally, the procedure is in variance with Section 3.9, paragraph 4 of the OAC/QAP above which requires an NCR to be prepared which identifies and describes the rienconformance. l s
RESPONSE
Section 3.9 paragraph 4 of the Operations Administrative Control and Quality Assurance Plant (OAC/QAP) states, in part: " Materials, parts and components which are determined to be nonconforr.iing, shall be identified and reported. Nc'iconfctmance reports shall be prepared which ic'entify and describe th6 nonconformance, the disposition of the nonconformance and reinspection or testing performed to determine the acceptability of the item after the disposition has been completed. 4 The term "nonconformance reports" as used in this paragraph was intended to have a broader defm~ ition than Nonconformance Reports ] (NCR's). The practice of using Work Request / Work Order and previously Maintenance Action Requests as nonconformance reperts has been in place since 1980. For nonconforming conditions dispositioned " rework" or j " scrap", the WR/WO meet all the requirements for identifying and describing the nonconforming conditions, the dispositions, and the reinspection and/or testing. l 1 10 { )
l i NRC FINDING l l The applicability statement of STA-405 requires nonconforming l conditions discovered -during receiving inspections-to be identified as nonconformances. In addition, the definition. of nonconformance defines deficient documentation ar a nonconforming condition. Contrary to this, STA-405 also allows items which are nonconforming during receipt inspection to be placed in a "QC Hold" area without preparing an NCR. Resnonse The practice described by this finding is accurate.
- However, procedure WHS-001, " Receiving and Inspection of Materials., Parts and Components",
requires that the Receiving Inspection Report be-checked UNSAT. and the discrepancy be described in the " Remarks" section of the RIR. A Receiving Hold tag is then attached to the item j and the item placed in a designa~ted hold area. At this point an attempt is made to retrieve the missing documentation. If the missing documentation is r-trieved then a reinspection is performed and, if acceptable, the RIR is checked SAT and the item accepted.for placement _into the warehouse. However, if the documentation is not received then an NCR is written, i 11
COMPARISON OF NONCONFORMANCE CONTROL PROGRAM TO CRITERION XY_ 10CFR 50 Appendix B, Criterion XV, " Nonconforming Materials, Parts or Components" states: " Measures shall be established to control materials, parts or components which do not conform to requirements in ord6r to prevent their inadvertent use or installation." This portion of Criteria XV is addressed in that STA-405 paragraph 4.1.1 requires that "All station personnel are responsible for reporting nonconforming conditions discovered." There are two methods outlined in STA-405: (1) the Work Request / work OMand,2) the Nonconformance Report (NCR). l 12
i .r 1 10CFR 50 Appendix B, Criterion XV, " Nonconforming Materials, Parts or Components" states: "These measures shall include, as appropriate, procedures for identification, documentation, segregation, disposition and notification to effected organientions.* These requirements of Criterion XV are met in the following manner: A. Identification - STA-405 requires that all personnel 1 report nonconforming conditions. In addition, various inspection, engineering and maintenance procedures also require reporting of nonconforming conditions in accordance with STA-405. B. Docuinentation - After items are released from the warehouse STA 405 requires that a_ nonconforming condition be identified either by a (Vork Request / Work ..'DrDr an NCR. In the casc of receiving, the item held pending receipt of documentalign without writing an NCR are documented as and LUNSAT on the Receiving ~ MMti6n~RIe@ The RIR cannot be closed without the RIR item checked SAT or an NCR written. 1 C Segregation - Items received into the TU Warehouse are procedurally required to be segregated or otherwise identified as not being receipt inspected. Once inspection is performed 'and the item is determined to be nonconforming, it is further identified as nonconforming and placed in a Nonconforming Hold Area. Items which are found nonconforming after release from the TU Warehouse generally cannot be segregated. However, items fcund nonconforming are identified by a Work Request Tag (when practical) which is placed on the nonconforming item. If an NCR is written, Hold Tags are i used (when practical) to identify the nonconforming conditions. Both the Hold Tag and the Work Request Tag are not attached under the foliewing conditions: 13
py (. a i ug L 3 x
- a.'
hanging the tag would be detrimental to the individual's safety; b. the individual's exposure to radiation will be unnecessarily increased; g-L c. the item is-on the main control ~ board in the-control room; and-d. the tag would interface with component operation. i D. Disposition - All nonconforming items are dispositioned as rework, repair, scrap or use as-is. Items which require engineering approval- (repair and use as i::) are documented on the NCR. Rework and scrap (replace) I dispositions restore the item to an existing engineered condition. M%dA l y E.- ND.tification - In the case of installed items found nonconforming while operating the plant, the shift supervisor is notified immediately so the plant can be placed in a safe operating condition should the condition warrant such an action. This requirement applies to the Work Request and the NonconformanceL Report. In cases where and NCR or. Work Request is' generated. on non installed items, the' person responsible for correcting the condition is notified. l i I l 14
L i ' 10CFR-50 Appendix B, Criterion XV, " Nonconforming. Materials,LParts - or: Comtsnents" states: " Nonconforming items shall be reviewed and accepted, rejected, repaired or reworked in accordance -with documented procedures." ~ These. requirements of Criterion XV are met in the following manner: The nonconformance control program requires that; a nonconforming. condition must be repaired, reworked, rejected (scrapped)' or . accepted (use.as is). The nonconformance control. program clearly: defines these dispositions and provides measures 'to' assure 'that engineering ' review is performed when necessary. .All dispositions must be-implemented in accordance with ? written procedures and/or - instructions. 15
O-i:- P 9 F CONCLUSIQN L 'TU Electric finds that -the nonconformance reporting program meets the provisions.of 10 CFR 50 Appendix B Criterion XV. However, the l TU Electric review of the program conducted as a result of the NRC . finding revealed that: improvements can be made in the program. A summary of these program enhancements which will be made follows: - Revise the OAC/QAP to more clearly define the specific use of the Work Request / Work Order as a nonconformance report. Revise procedures to to clearly. define the use of the term. " invalidate." Revise. WHS-001 to more clearly define placing items on a hold without writing and NCR. -Revise procedures to clearly describe the use of the Equipment History Program in identifying repetitive, ' vendor ' deficiencies, i-o. Revise procedures to clearly. describe Operations role and responsibility in timely review of Work Requests / Work Orders for 10CFR21 and 50.55(e) reportable conditions, i i 16

Texas February 16. 1987 3,i,j ca Comanche Peak _ Steam Electric Station Testing of 6.9KV Switchgear Both trains' of 6.9KV class 1E Switchgear are in the process' of being. de-energized for rework of cubicle mounting and installation deficiencies. This work will require determination of all 6.9KV power and control cables that are terminated in each switchgear cubicle. All switchgear work and 3 testing vill be controlled by Construction Work Orders per STA-806. l Startup.is responsible for work restoration and retest plans for the 6.9KV switchgear. CWO C87-0669 will document Startup. testing of Train A 4 Switchgear and another CWO under preparation will document Train B Testing. Testing should commence sometime near the end of summer and will be based on the following startup prerequisite testing. t XCP-EE-1 Megger/Hi Pot Testing XCP-EE-5 Switchgear and Motor Control Center Testing XCP-EE-8 Control Circuit Punctional Testing l XCP-EE-9 Initial Motor Rotation & Run-in (rotation check only) XCP-EE-12 Annunciator and Monitor / Status Light Operability Testing XCP-EE-20 Continuity and Termination Verification I It is anticipated that prior to re-energizing the switchgear per EE-5, thet EE-20 and EE-8 testing will be performed on all internal wiring and field cables to verify feeder breaker control circuits, bus undervoltage circuits, and bus synchronizing and breaker control circuits. - Depending on construction work progress, either breaker test linkage will be used for EE-8 control circuit functional testing if the bus is energized or dead bus EE-8 control circuit functional testing will be performed if the bus is de-energized. After the bus is re-energized and functionally tested, final testing will be a motor rotational check per EE-9. Rotational checks per EE-9 will be coordinated with operations systems procedures. In those situations where system configuration precludes pump operation, unceupled motor runs will be performed, Startup functional testing should be adequate to satisfactorily post work test cable terminations as well as 4 ' demonstrate motor and switchgear operability. Surveillance testing to be performed during plant operational testing at a later date will substantiate startup functional testing and serve as a second check. In particular, the following surveillance tests will 'directly demonstrate 6.9KV bus operability as required by Technical Specifications. 1 EGT-766 6.9KV Safeguards Bus Power Supply Transfer and Response Time i Test, Train A EGT-767 6.9KV Safeguards Bu's Power Supply Transfer and Response Time Test, Train B ECT-770 Integrated Safety Injection / Blackout Test Train A ECT-771 Integrated Safety Injection / Blackout Test Train B g g e

not 'y TIM-870143 Fsbruary 16, 1987 .Page 2 As circuit design modification is not being performed, it has been recommended that startup prerequisite testing be used to post work test all 6.9KV switchgear work. PPF-164, "SSW/CCW Low Header Pressure Auto Start" " is the only outstanding design modification involving 6.9KV switchgear. Its implementation was in progress prior to the 6.9KV rework and will be independently tested per EGT-TP-86A-10 when Train A and B SSW and CCW i Systems are operable. From a 6.9KV switchgear rework point of view, l ,Results Engineering performance and test group involvement would be .f minimal. It is anticipated that Results Engineering immediate scope of 3.j - y involvement include: { sm.. .x o p'@ijid. k"dI - review of proposed startup prerequisite tests - special test issue resolution as required - coordination of EE-9 motor rotation checks with operation's integrated testing activities.
