Preventive Maintenance Task Comparison

DOE-STD-1052-93

8.2

Once the PM task selection process is complete, a task-by-task comparison of the

selected, applicable, and effective tasks is made with existing activities and vendor

recommendations. The comparison should include all existing PMs, surveillance tests,

in-service inspection tests, performance tests, and calibrations for the component

being analyzed. Operator rounds or other routine inspections are often overlooked

as recognized tasks, but they also should be recorded. After they are recorded, these

tasks and activities may be compared to vendor-recommended activities, inspections,

and tests.

It is important to establish the basis of the vendor PM recommendations to help

resolve any differences between the recommendations and PM tasks. For example,

were the vendor recommendations based on continuous or intermittent operation of

the equipment? The source or requirement for each PM task should be determined

and listed. Assistance from the groups responsible for tracking commitments may be

helpful in identifying these requirements. Examples of sources include the following:

technical safety requirements

vendor technical manuals and bulletins

DOE technical documents

insurance requirements

in-service inspection (ISI) requirements

plant operating and maintenance experience

other commitments

The contents of newly defined PM tasks are compared with existing tasks. Any newly

selected task not addressed by an existing task should be proposed as a new PM task.

Any existing task not supported by the analyses should be considered for deletion as

an unnecessary task. Caution should be exercised before deletion of any task. Prior

to deletion, a review should be performed to ensure the deletion does not invalidate

a commitment or an assumption made in the analysis process. If a commitment may

be impacted by deletion of the task, then consideration should be given to requesting

a change to the commitment.
