EC.IC-GP.ZZ-0008(Q) 1.0 PURPOSE 1.1 The purpose of this procedure is to provide Maintenance

(

personnel with administrative troubleshooting widance that interfaces with station procedures and policies.

1.2 To provide administrative controls to ensure compliance with NC.NA-AP.ZZ- 0013 (Q) by providing Attachment 2 to document temporary modificat_ ions made IAN other procedures.

1.3 This procedure is not required provided that the troubleshooting is limited to the measurement of parameters NOT requiring jumpers or lif ted leads.

1.4 To provide a source of current information via component attachment sheets on known component problems.

2.0 PREREQUISITES 2.1 Administrative 2.1.1 The Job Supervisor has verified that the-individual assigned to perform this procedure is qualified to do so IAN HC.MD-AP.ZZ-0014 (Q), e Maintenance Qualification and Training Program.

2.1.2 The Senior Nuclear Shift Supervisor / Nuclear Shif t Supervisor (SNSS/NSS) has granted administrative authority for the performance of this procedure.

2.1.3 If applirsble, a Radiation Work Permit (RWP) has been obtained.

2.1.4 The work package has been reviewed by the Job l

Supervisor for completeness and any special administrative prerequisites have been noted and addressed.

2.1.5 Applicable personnel and equipment safety precautions have been complied with IAN station administrative procedures.

2.1.6 Working copies of documents used shall be validated and st g ed by the Job Supervisor IAW NC.NA-AP.ZZ-0003(Q).

2.2 System CD-588A 2.2.1 If applicable, ensure the NCO resets any existing half scram prior to the start of any l

l l

BC.IC-GP.ZZ-0008(Q) 2.2.3 Circuits shall be analyzed for inadvertent

}

e pipment operation and the initiation of trip i

2 signals caused by the placement of jumpers, or

(

lifting leads prior to their use.

2.3 Definitions Test A controlled set of plant operations intended to verify that the systems, structures or components function in accordance with predetermined specifications. Such tests would be of significance to the degree that they should be described in the SAR, could affect safe operation of the plant, could degrade the margins of safety during normal operations or anticipated transients, or degrade the adequacy of structures, systems or components used to prevent accidents or mitigate accident conditions. This may include operation of systems or components outside their normal configuration or addition of new components or systems not described in the SAR.

Experiment - A controlled set of plant operations intended to establish characteristics not previously known. Such experiments would be of significance to the degree that they should be described in the SAR, could affect safe operation of the plant, could degrade the margins of safety during normal operations or anticipated transients, or. degrade the adequacy of structures, systems or components used to prevent accidents or mitigate accident conditions. This may include operation of systems or components outside their normal configuration or addition of new components or systems not described in the SAR.

3.0 PRECAUTIONS AMD LIMITATIONS 3.1 Ensure that the Nuclear Control @erator (NCO) is instructed as to which specific alarms and indications will be affected by the performance of this procedure.

3.2 Ensure that M&TE used is set to the proper function and range prior to its use.

3.3 IE it is suspected that the test epipment may not be performing properly, THEN a comparison check shall be performed with a similar device QR the device shall be checked for calibration against a standard.

This shall be done prior to taking any other corrective action.

3.4 Ensure that all Measuring and Test Equipment (M&TE) has a current calibration sticker, and is controlled IAh NC.NA-AP. ZZ- 0022 (Q).

3.5 If appropriate, ensure that a manufacturer recommended warmup period is provided for all instrumentation and M&TE.

EC. IC-GP.ZZ- 000 8 (Q) 3.6 If venting and/or draining an instrument, or instrument line, contain and dispose of all liquids IAW the RWP or established safety practices.

3.7 Discrepancies noted during the performance of this procedure shall be documented IAW NC.NA-AP.ZZ-0020(Q).

3.8 Devices installed using torque paint on mounting bolts, etc. shall not be removed for bench calibration.

In addition, the ASME pressure boundary shall not be compromised.

The ASME pressure boundary is identified on drawing 10855-J-G-1010-3.

3.9 Second party (independent - an individual different from the person making the change) verification shall be required for each Q, F or R listed lifted lead, pipe l

disconnected, jumper (wire, staple, etc.), or instrument valve repositioned under this procedure.

i l

3.9.1 All leads shall be marked (ie - color coded, I

conductor number and/or permanent label. IE the leads are not marked in this manner, IEEN a temporary marker shall be installed. The temporary marker shall be removed when the lead is re-connected, a

l CD-596F 3.9.2 All Relay Department personnel shall fill out Attachment (s) 5 for each listed lifted lead or jumper (wire, staple,'etc..) not listed in HC.RL-PM.ZZ-00011Q).

CD-326G 3.9.3 The number of wires on a terminal post shall be determined, documented, and independently verified prior to altering the wiring configuration on that terminal. The number of wires shall be verified to be correct after restoration of wiring on an affected terminal post. The column provided on Attachment 2 (5 for relay department) shall be used for this purpose.

3.10 When a difference between the installed epipment and CD-136A the documents being used for troubleshooting exists,

, resolution shall be obtained from the Job Supervisor before proceeding with the troubleshooting effort.

3.11 Only the materials and solvents approved by NC. NA-AP. ZZ- 0038 (Q) may be used in the performance of this procedure.

3.12 When appropriate, equipment shall be properly tagged IAW NC.NA-AP.ZZ-0015(Q) prior to perfo M ng any work.

3.13 Jumpers or lifted leads which must remain at the completion of the work QR if the work activity is stopped for more than two shifts shall be administratively controlled IAW NC.NA-AP.ZZ-0013(Q).

HC.IC-GP.ZZ-0008(Q) 3.14 The use of grounded M&TE shall be limited to CD-691A applications where isolation from power supply grounds are possible unless determined that the M&TEs use will

(

not produce adverse effects on the circuits under test.

3.15 Whenever possible, steps shall be taken to troubleshoot in-plant equipment in the de-energized state.

3.16 Lifted leads must be suitably insulated from other circuits and electrical grounds. Exposed electrical leads must be taped or insulated when left unattended.

l 3.17 Electrical jumper cables must be of sufficient length and contrasting color to stand out from other cables.

l The use of " alligator clips", clamps or other l

attachments subject to inadvertent disconnecting is discouraged.

3.18 Mechanical jumpers must be marked uniquely to stand out from other hoses or pipes. The temporar tag may be sufficient for this purpose.y modification However, in some cases, additional marking may be needed (additional tags at regular intervals for long jumpers).

3.19 Cogonent attachment sheets must be reviewed for applicability in the course of troubleshooting.

4.0 EQUIPMENT REQUIRED The test equipment used in the performance of this procedure 1

shall be as needed.

The M&TE used shall be documented on 1

energized when it affects electrical, electronic, pneumatic or hydraulic parameters on equipment, systems t

or components which are not isolated from service.

i Normal routine isolation of epipment where the process is not expected to be affected (eg. operation of instrument isolation valves on non-sensitive racks) is exempted from this definition. Isolation will normally be accomplished via test / bypass switches, electrical breaker operation, fuse removal and/or isolation IAW HC.SA-AP.ZZ-0015(Q).

5.1.1 Ensure all prerequisites have been satisfied.
