Problem Component Analysis

DOE-STD-1052-93

Following completion of Sections 6 or 7, selection and implementation of applicable and

effective PM tasks are performed as described in Section 8, "Preventive Maintenance Task

Selection and Implementation." Selection of condition monitoring (predictive maintenance)

tasks is emphasized before selection of time-directed PM tasks. If an applicable and

effective PM task cannot be determined, the process involves an evaluation to determine

the feasibility of a design change or other corrective actions.

Maintaining an effective PM program is described in Section 9, "Preventive Maintenance

Living Program." Experience gained from plant operations, maintenance, and the

installation of design changes dictates frequent review of the enhancement analysis and

revision of the PM program to maintain program effectiveness.

6. PROBLEM COMPONENT ANALYSIS

This section describes a process that may be used to analyze problem components and

identify any PM activities that may improve component reliability. The type and level of

maintenance performed on a component should be based on its importance to the plant with

respect to nuclear safety and reliability. The effort to enhance a PM program should start

by focusing on these components. Although several analytical techniques may be used, the

technique described in this section is a functional failure analysis that is commonly used in

reliability-centered maintenance programs. The analysis described in this section includes

the following:

problem component selection

component boundary determination

component history review

selection of analysis technique

determination of functional failures

determination of failure modes and effects

After the problem component analysis is complete, selection and implementation of

applicable and effective PM tasks may be performed as described in Section 8, "Preventive

Maintenance Task Selection and Implementation."
