'1. 0 PURPOSE The purpvse of this procedure is to describe Planned Maintenance administration and control to be implemented at Plant Vogtle. (Commitments 2497, 8571, 16400, 185, 15893, 12305, 13484, 12341, 5902, 5899, 1495, 193, 11276, 13189, 12163, 11930, 192, 2602, 3321, 2604, 50176, 2609, 2599, 1712, 7400, 2603, 8743, 6105, 6373, 7154, 7157, 7158, 7824, 10030, 10031, 12541, 14987, 15661) 2.0
[EFINITIONS 2.1 PREVENTIVE MAINTENANCE (PM)
Time dependant, condition dependent and
. rend / analytical task performance to assist in reducing uplanned outages, equipment failures and enhance Plant availability.
2.2 PREVENTIVE MAINTENANCE CHECKLIST / STANDARDIZED CHECKLIST (SCL) i A checklist with standard maintenance tasks to be performed on specific equipment tags to the equipment or equipment type (refer to Figure 3 for typical i
organization).
A PM Checklist that provides standard h
maint.cnance tasks to be performed on a specific equipment tag.
The SCL may be generic in nature in that it may apply to numerous, similar equipment tags.
NOTE
.f t
Tha PM Checklist is developed with the personnel who will g
- perform the equipment maintenance in mind.
It is intended to be ys p~'N N
a working tcol for the individual performing the work but is not a Q'
. W replacement for a procedure for major overhauls or other detailed b
work.
The checklist will generally (b.*
inform the individual what needs to i
_.)
be done.but may not give detailed instructions on what is needed to c
perform the task.
The checklist l-may make reference to a specific procedure or other document as required for detailed instructions.

WOCEDULE NO 84Evt$10 N P AGE 40 VECP 20015-C 11 3 of 18 2.3 PREVENTIVE MAINTENANCE REPETITIVE TASK FILE
\\--
A file in NPMIS developed for generation of PM MW0s.
2.4 PREVENTIVE-MAINTENANCE CHANGE REQUEST FORM (PMCR)
A document used to implement changes to improve the effectiveness of the PM Program.
(Refer to Figure 2 for a typical format.)
2.5 MAJOR CHANGE OF A PM CHECKLIST A major change is any change that would alter the scope or intent of the PM Checklist for example; revising a SCL class, revising the frequency of the SCL for a particular equipment tag, adding or deleting steps on a checklist and adding or deleting the applicability of an equipment tag to a SCL.
2.6 MINOR CHANGE OF A PM CHECKLIST A minor change is any change that is not technical in nature and does not alter the scope or intent of the PM checklist.
Minor changes will not require revision change.
The intent of the Minor Change process in to achieve proper documentation of minor, non-technical s
(' -)
changes while allowing field or packaging work to continue.
Examples are; correcting an incorrect reference procedure, revising a REP task for a time dependent PM and clarifying work instructions for checklist steps.
2.7 EQUIPMENT QUALITICATION TASKS Maintenance tasks identified in equipment qualification packages (EQDPs) that are required to maintain the equipment qualification.
The EQDP revisions will be evaluated and incorporated into the Preventive Maintenance Checklists or Maintenance Procedures as necessary.
(Reference Procedure 20009-C) (Commitments 7824, 10030) 2.8 PREVENTIVE MAINTENANCE <ERIODICITY Periodicity is the frequency at which time dependent PM tasks are scheduled to be performed or the suggested frequency for which the condition Dependent PMs may be performed.
The early and late date tolerances for' performing required PM task are given in Figure 4.

These tasks will have recommended frequencies but will not generate a MWo unless specifically requested, and will nct have late cates.

This is maintenance identified that should be performed on the subject equipment.
These tasks are considered good maintenance practice and are based on vendor recommendation, industry standard, or-industry experience.
C COMMITMENT MAINTENANCE This is maintenance that is required by a plant commitment
- contained in the Commitment Tracking System.
E EQDP REQUIRED MAINTENANCE This is maintenance that is listed in Section G of the Equipment Qualification Data Packages that must be performed to maintain qualification (operability) for the piece of equipment.
This classification applies to both 10CFR50.49 equipment as well as equipment in a mild environment.
R EQDP c 20MMENDED MAINTENANCE I
\\
This is maintenance that is identified in Section G of
\\2 the EQDP that the respective vendor recommends to be performed on a specific type of squipment.
The performance or lack of performance of this type of maintenance does not render a component unqualified.
This type of EM is to be performed on mild environment EQ equipment in lieu of component replacement.
S SECURITY MAINTENANCE This is periodic maintenance that is performed on security system components to meet the intent of licensing requirements.
Maintenance identified on Classes, C,
E and S standardized checklists is considered to be raquired maintenance, that is to say Time Dependent.
Maintenance identified on Classes A and R standardized checklists and maintenance identified on non-standardized type checklists should be considered to be good maintenance practice but is not required by l
plant commitments unless noted otherwise, that is to l
