A.7 PREVENTIVE MAINTENANCE

PERFORMANCE OBJECTIVE

Preventive maintenance should contribute to optimum performance and reliability

of plant sy stems and equipment.

CRITERIA

A. A preventive maintenance program is effectively implemented and includes

sy stems and equipment that affect safe and reliable plant operation. Preventive

maintenance includes equipment layup protective measures, where applicable.

B. Preventive maintenance, including predictive maintenance activities, are

performed at appropriate intervals. These intervals maximize equipment

availability. Considerations such as operational experience, vendor

recommendations, engineering analysis, and cost/benefit analysis are used as a

basis to establish preventive maintenance tasks and intervals.

C. Preventive maintenance activities are scheduled and performed within

established intervals. Preventive maintenance is waived or deferred only with

management approval.

D. Preventive maintenance documentation provides a record of activities performed,

data collected, and, where appropriate, the "as-found" and "as-left" condition of

the equipment.

E. Preventive maintenance techniques and results are used to assess equipment

performance. Program adjustments are made and other corrective actions are

taken where needed.

F. The effectiveness of the preventive maintenance program is periodically

evaluated at an appropriate level of management, and the results are used to

make program improvements.
