PURPOSE.

1.0

This procedure describes the responsibilities and steps necessary to perform walkdowns for the

purpose of establishing the as-found physical configuration of the facility, and identifying any

discrepancies with the associated facility documentation.

2.0

OBJECTIVES.

The

objectives of the CM walkdowns are to:

Establish the as-found physical configuration of the facility

Identify any discrepancies between the as-found configuration and associated facility

documentation

3.0

SCOPE.

This document applies to all formal efforts by facility and contractor personnel to reconstruct missing

data or field verify existing Equipment Database information through walkdowns on mechanical,

electrical, and instrumentation and control (I&C) systems. This will be accomplished by performing

the walkdowns on a system-by-system basis to identify the as-found physical configuration and to

obtain missing nameplate data for inclusion into the CM Equipment Database.

REFERENCES.

4.0

The following are examples of relevant types of documents that should be identified and referenced In

support of this walkdown effort:

Drawings (e.g., P&IDS, schematics, location drawings, vendor drawings, etc.)

Operations Procedures (e.g., system startup, system operations, etc.)

QA Procedures (e.g., non-conformance items, field deviation notices, drawing change

notices, independent verification, etc.)

Equipment Database Procedures

Engineering Procedures

Maintenance Procedures (e.g., work request, scaffold erection, etc.)

Security and Safeguard Procedures

Radiation Protection Procedures (if applicable)

Special Requirements covering EQ, fire protection, etc.

Safety Analysis Report

KEY DEFINITIONS.

5.0

Walkdown: A visual inspection of facility SSCs to identify the as-found physical configuration

and any discrepancies with currently approved facility documentation.

Nameplate: The plate or label attached to a component by the manufacturer to provide

applicable component identification and design data, such as temperature, pressure, flow etc.

Walkdown team: Personnel responsible for gathering information during the walkdown, and

for verifying and documenting the accuracy and completeness of this information. For this

effort, each walkdown team should consist of at least two qualified personnel.
