g I. PURPOSE This procedure provides instructions to personnel performing station maintenance or implementing plant modifications to ensure that:

A. Technical Specification requirements are adhered to. ,

B. Quality is at least equivalent to the original design and that appropriate quality requirements are specified.

C. Personnel and equipment safety are assured.

II. DISCUSSION A. Maintenance Request Form The Maintenance Request (MR) Form (Attachment A) is used as an ad-ministrative tool to assure that the requirements of this procedure are documented.

B. Maintenance Summary and Control Form The Maintenance Summary and Control Form (Attachment D) is an ad-ministrative tool utilized to further define the work to be per-formed including special tools, equipment, procedures, instructitas, expected exposure levels and to provide feedback when the work is completed.

C. Planned and Backlossed Maintenance When the planning for an MR is completed, per paragraph VII.0, and ,

-the work is scheduled for a later date, or the work requires a power reduction or an outage, sufficient time should be allocated for a radiological review and for planned maintenance scheduling by the l

l~

Sr. Engineer for Outages and Modification.

D. Unplanned, Emergency Maintenance For maintenance that requires immediate response, which precludes meeting all the administrative controls of this procedure, the Oper-ations Supervisor may initiate corrective maintenance in accordance l with Administrative Procedure 1.5.7.

E. Cancellation of MR's

!~ When an MR is cancelled by the OS, COE, CME, CTE or CMG Leader, the

or-ginator of the MR shall be notified of the cancellation and the l- reason for this action.

Preventive Maintenance Preventive Maintenance (PM) is defined as "the planned periodic inspection, servicine, adjustment, replacement and repair of plant assets and equipment to maximize the availability of production generating facilities and enhance the effectiveness and efficiency of maintenance resources".

Corrective Maintenance Corrective Maintenance is the repair or rework of plant assets to restore them to their specified operating condition.

IV. PREREQUISITES A. Station Maintenance Station maintenance shall be performed in accordance with approved PNPS procedures, approved Temporary Procedures per Procedure 1.3.4, or as defined in ANSI 18.7. (Except shop work, routine maintenance not affecting equipment, surveillance testing and calibrations -

.w hen no tagging /isolations are required.)

B. Plant Modification Plant modification shall be implemented with the requirements of the

" Approved for Implementation" Plant Design Change Request (Procedure 1.3.13).

v. APPARATUS N/A VI. PRECAUTIONS A. Redundant Components Separate Maintenance Requests will be submitted when similar work is required on redundant components.

B. Multiple Work Items When an MR is processed that includes more than one item of work within an isolation, and work is complete except for one or two items, the existing MR should be signed off and a new MR generated for the remaining items. The new and completed MR's shall reference each other. .

C. Additional Work When it becomes apparent that the scope of work defined on the MR is not sufficient to satisfactorily complete the assignment, a new MR shall be instituted with the same number and an alpha suffix.

D. Approval Requirements Positions shown for review / approvals in this procedure shall also include designated alternates acting in the positions indicated.

The only exception to this policy is the Watch Engineer's approval required to isolate the system.

E. Approval for Work Start No maintenance is to be performed at Pilgrim Station without the

" APPROVAL FOR WORK START" block on the MR being completed.

F. Maintenance activities which result in the " replacement" of "not-in-kind" components will be administered by the appliance of the " temporary modification" procedure 1.5.9 or "PDCR" 1.3.13 as applicable which requires the performance of a safety evaluation to determine whether or not the replacement can be safely installed and/or operated in addition to providing the basis that determining an unreviewed safety question does not exist or whether a technical specification will be inhibited or overridden.

G. If modification to safety related components are to be implemented using the maintenance request as a vehicle, controls of work per-formance and documentation may be more restrictive than those within the a602tenance request procedure. In these cases, the appropriate procedures and governing codes will be used.

H. Repairs to safety related systems, structures and components will only be made in accordance with an approved repair program with ,

repair procedures which comply with the ASME Code Section XI Sections IWA 4130, IWB 4200 and 4300.

I. PROCEDURE

A. The processing of the MR by personnel performing work at the station is described below and summarized in Attachment E. Each review of the MR should be expedited to allow timely beginning of maintenance activities.

1. Originator

-The originator provides the following information:

a. Date
b. Equipment and Equipment No.
c. Location
d. P&ID No. if applicable
e. A clear problem statement with sufficient detail to describe the request.

Date and Time What - Describe situation Where -

Give location of situation (physical and functional)

When -

Under what plant conditions does the situation occur?

Extent - How big is the devation? Is it tending to remain constant, increase, or decrease?

Signature NOTE: Provide as much information as you can.

f. Applicable references such as a PDCR, temporary modifi-cation or associated c.aintenance requests. This is in addition to a clear problem statement.

The originator then signs and dates the MR and submits it to the Operating Supervisor.

2. Operating Supervisor (OS)

The OS reviews the problem / work required and performs the fol-lowing functions:

a. Checks the Maintenance Request Log for duplication. If it is a duplicate, he notifies the originator, cancels the MR and updates the log and/or files as required: if not, he proceeds to:

b. Enter System No.
c. Priority per Attachment F.
d. Identify need for isolation per Procedure 1.4.5.
e. Identify need for RWP per Procedure 6.1.22 VI. A.
f. Record required data on Watch Engineer's Maintenance Re-quest Log by stem and assign an MR Log No. to the MR.

The NOS then forwards the MR to the Chief Operating Engineer.

3. Chief Operating Engineer (COE)

Chief Operating Engineer (COE) checks the MR for correctness and completeness and reviews work requested.

a. If he agrees, the COE adds any pertinent information, verifies the priority assigned, signs and dates the MR.

and forwards it to the Chief Maintenance Engineer (CME) for mechanical and electrical for instrumentation and con-trols work.

4. Chief Maintenance (CME)

The respective Chief Engineer reviews the MR for correctness and completeness and verifies the need for maintenance support, judges priority, safety implications, special group handling.

a. If the CME agrees with the MR, he signs it and dates it and assigns it for implementation. The MR is then for-warded to the Maintenance / Technical (M/T) Secretary.

l_

b. If the CME does not agree with the MR, he resolves the is-
sue with the COE. If the MR is cancelled, the CME writes

" CANCELLED" on the MR and forwards it to the M/T Secretary for logging and returns to the OS who cancels it.

The CME will perform a semi-annual review in January and July of open maintenance requests to determine if priori-ties should be changed, responsibilities should be re-assigned or MR's should be combined, expedited, cleared or cancelled. This review will be documented on Attachment l 1.5.3H-1. If an extended outage is in progress when the

! review is scheduled, it may be rescheduled for a later time. Form 1.5.3H-1 will also be used for this purpose.

5. Maintenance Secretarv The M Secretary assigns the MR . the next sequential depart-mental number perfixed with an M for Maintenance or an I for Instrumentation & Controls, records the required information in the respective departmental Maintenance Request Log (Attachment C) and forwards the MR to the Staff Engineer.
6. Staff Engineer (SE)

The S.E. reviews the MR and further defines the work to be done by working with the originator and supervisor and determines plant conditions necessary to accomplish the work and reviews priority by consulting with the NOS. .-

The Staff Engineer will determine if the activity is on a safety related item and indicated Q-List # if applicable.

The MSE will next determine whether or not the maintenance ac-tivity constitutes a modification. If it is a modification, indicate temporary or plant design change request. If it is a temporary need, refer to procedure 1.5.9. If it is a PDCR, refer to procedure 1.3.13.

CAUTION Maintenance activities conducted under Procedures 1.5.3 or 1.5.7 may not perform modifications to the plant. Procedure 1.5.9 is to be used for temporary modifications and procedure 1.3.13 for changes in plant design (PDCR's).

A maintenance activity will be considered a modification if the system, structure or component being maintained would no longer conform to it's original design documents as changed by sub-sequent authorized design changes.

The MSE may complete the MSC (Attachment D) addressing the fol-lowing items, when required.

a. Special tools, equipment and material required.
b. Staffing requirements.
c. Estimated Radiation Expcsure Levels.
d. Approved Documents (procedures, tests, etc.).
e. Determination of quality requirements, specifies them, and ensures that they are at least equivalent to the original design basis.

NOTE: A review of the historical visi-record files may provide much of this information.

( SYSTEM PRIORITIES INTRODUCTION The Maintenance Request (MR) priority is determined by the' Watch Engineer (WE) who app. oves the MR and is assigned, based upon the WE's knowledge and judge-mes.t of station requirements, operation procedures and good operating practics.

All MR's shall be assinged one of the priorities discussed below.

All MR priorities shall be reviewed by the Chief Operating Engineer (COE) and the Chief Maintenance Engineer (CME) to determine if conditions have changed to a point where the MR's priority should be revised. However, the WE's priori-ty assignment may be changed only by the Chief Operating Engineer (COE) or by the Chief Maintenance Engineer (CME). Any priority changes shall be initialed and agreed upon when performance of either department is impacted.

All maintenance work will be scheduled so that higher priority work will be completed before lower priority work is started and for equal priority work, the oldest MR will be scheduled first (unless other factors intervene).

MAINTENANCE REQUEST PRIORITIES The WE will determine if the work requested on the MR can be accomplished dur-ing normal plant operation (Running Repair), only when the plant is operating at reduced power levels (Power Reduction), or only when the plant is shut

( down (Outage). The WE will then assign priorities based upou the following

\ criteria:

FOR RUNNING REPAIRS AND UNPI.ANNED EMERGENCY REPAIRS:

One of the three priorities shall be assigned as follows:

PRIORITY A - This priority shall be used only on those MR's prepared to correct conditions that have or soon will cause:

- I,0SS OR MMOR REDUCTION OF GENERATING CAPACITY

- EXTREME SAFETY, SECURITY, OR RADIATION CONTAMINATION HAZARDS MAJOR EQUIPMENT DAMAGE Use of priority 'A' would be done on an emergency basis and would necessitate stopping of lower priority work in progress, use of overtime and call-in of off-duty main-tenance personnel. Any needed repair parts or speciel tools not available on site shall be ordered on an emer-gency basis with continuing requisition follow-up. If necessary, repair parts and/or special tools are not available on stie, use of overtime and/or call-in of s maintenance personnel shall be minimized. (Also see

/' Procedure 1.5.7- Unplanned, Emergency Maintenance.) .

NOTE: An 'A' priority can also be issued upon consul-(j '

tation with theCOE and either the CME or the CTE on the subject MR.

( ,

PRIORITY B - This priority shall be used on those MR's prepared to correct conditions that have or may cause:

MINOR LOSS OF GENERATING CAPACITY fh LOSS OF BACK-UP SYSTEM / EQUIPMENT WHERE LOSS OF PRIMARY SYSTEM WILL RESULT IN PRIORITY 'A' REPAIRS 3 - SAFETY OR RADIATION CONTAMINATION HAZARDS LONG TERM DAMAGE TO EQUIPMENT SITUATIONS CAUSING LOSS OF WORKER PRODUCTIVITY / MAJOR DISCOMFORT Use of priority 'B' would normally not necessitate stoppage of lower priority work in progress nor call-in or overtime by maintenance personnel; howeves, priority 'B' MR's should be scheduled for work ahead of all lower priority MR's. Any special tools and/or repair parts not on site shall be ordered in a normal manner with weekly follow-up of the

~

requisition.

PRIORITY C - This priority shiell be used on all Rur ling Repair MR's C- not meeting the criteria for priorities ' A' or 'B' . Work on priority 'C' MR's normally will not require overtime nor call-in of maintenance personnel. Special tools or repair parts not on site will be ordered in a normal manner with requirition/ order follow-up.

PRIORITY S - The 'S' priority shall be used for Security Maintenance Requests that affect plant security and are not meeting the 'A' priority criteria. Any material or spare parts not on site shall be ordered expea ously. Work on priority 'S' MR's shall be scheduled upon procurement of material and shall be given greater importance than

'B' priority MR's when scheduling maintenance work.

Normally, 'S' priority MR's will not require overtime nor call-in of maintenance personnel.

FOR POWER REDUCTION OR OUTAGE REPAI_RS_

.For maintenance work that can be performed only at reduced power levels or during a unit outage, the WE shall assign the following priorities:

PRIORITY B - This priority shall he used on all MR's that can only be done at reduced power levels.

s PRIORITY 0 - This priority shall be used on all MR's that can only be

/

done during a unit outage.

'f tween the COE and CHE or their designated representatives.

R.1 or 0.1 - MR's that shall be completed prior to return to normal unit power levels / unit start-up.

R.2 or 0.2 - MR's scheduled for work during unit pow'er reduction / outage after completion of R.1/0.1 work is assured.
