APPENDIX D

EXAMPLE METHODOLOGY

PREVENTIVE MAINTENANCE PROGRAM ENHANCEMENT

1. PURPOSE

The purpose of this document is to provide guidance that may be used to enhance an

existing preventive maintenance (PM) program by improving the reliability of plant

components and systems while optimizing resources. The implementation of this guidance

should help ensure that PM tasks for important components are applicable for the types

of expected failures and are effective in controlling the failures.

2. SCOPE

This document describes the elements necessary to enhance a preventive maintenance

program. The following items are addressed:

overview of enhancement method

problem component analysis

problem component selection

system analysis

system selection and prioritization

data collection

system and subsystem boundary determination

determination of system and subsystem function(s)

determination of functional failures

functionally critical equipment selection

analysis strategy for critical and noncritical equipment

determination of failure modes and effects

history review

preventive maintenance task selection and implementation
