DOE-STD-1052-93
Analyst/Reviewer
Responsible for reviewing SSC requirements, characteristics, and history to determine PM
or operational tasks needed to maintain or achieve desired levels of component reliability.
5. OVERVIEW OF ENHANCEMENT METHOD
Before the enhancement effort is started, the objectives to be achieved should be clearly
established by management. In establishing the objectives, the status of the existing PM
program should be considered. For example, objectives a plant may establish to enhance
a weak PM program may focus more on equipment reliability and documentation of the
basis for existing tasks. A plant with a well-established PM program may have an objective
to improve utilization of resources and optimization of selected technical safety
requirements for PM activities.
It is important that all groups involved in the development or performance of PM tasks
become familiar with the stated objectives and participate in some portion of the analysis
effort. This should produce more comprehensive results, enhance ownership of the
program, and facilitate implementation of changes to the existing PM program.
The PM program enhancement method provides two analytical processes, problem
components analysis and system analysis. Each process is followed by PM task selection
and implementation. The final element of the enhancement method is establishment of a
living PM program that is continually updated, based on actual equipment performance, to
maintain its effectiveness.
Problem component analysis is described in Section 6. This analysis focuses on improving
reliability of problem components by determining failure modes and implementing any
needed PM tasks or design changes.
System analysis is described in Section 7. This analysis focuses on improving overall
reliability of plant systems by determining failure modes and implementing PM tasks or
design changes. This analysis improves the use of resources by identifying existing PM
tasks and technical safety requirements that may be redundant or unnecessary. Additionally,
this analysis identifies noncritical components that may be evaluated to determine if assigned
PM tasks are cost-effective with respect to resources and radiation exposure or
consequences of failure. The review of noncritical components often provides the greatest
opportunity to optimize the use of available resources.
