APPENDIX G - CONDUCT OF WALKDOWNS

This appendix provides an overview and discussion of selected key issues related to

configuration management walkdowns.

A generic configuration management component walkdown procedure is provided for use

in developing detailed walkdown procedures. The following discussion addresses

selected key issues that should be considered when developing a walkdown program.

Walkdown Objectives. The objectives of the configuration management walkdowns are

to:

Establish the as-found physical configuration of the facility and

Identify any discrepancies between the as-found configuration and associated

facility documentation.

Critical Component Characteristics. Central to the success of the walkdown effort is the

identification of critical component characteristics. These characteristics provide the

structure for the component data sheets, which are used to collect, document, and

transmit the data for inclusion into the equipment database. Prior to the commencement

of the configuration management walkdowns, critical characteristics for each system and

component should be identified in the walkdown procedures. Acceptable sources for

these characteristics are the available design requirements, industry codes and standards,

comparison of the critical characteristics with similar systems and components, and

engineering judgment. The following are examples of some critical characteristics for

mechanical, electrical, and instrumentation and control components:

Mechanical Components:

Component number

Flow diagram number

Manufacturer

Model number

Serial number

Style/type

System

Size (e.g., pipe size, flow, critical velocity, etc.)

Pressure rating

Temperature rating

Material

Operator type (if applicable)

Orientation

Other (e.g., locking devices, extensions, etc.)
