Design Reconstitution Interface

DOESTD107393

The CM equipment database should contain and correlate the following information:

System designators

Component designators

Component descriptive information such as type, manufacturer, model, and size

Design requirement types applicable

SSC grade (based on the most Important design requirement applicable)

Design requirements or, at a minimum, references to them

Design basis references

Design topical area references (e.g., seismic, environmental qualification, fire protection)

Facility document references (e.g., drawings, procedures, Safety Analysis Report (SAR) and

Technical Safety Requirement (TSR) sections)

Other desired system and component information

A simplified sample format for a basic CM equipment database is provided as Figure 26. The actual

format, contents, and capabilities of an organization's CM equipment database will depend greatly on the

identified needs and intended uses.

As part of the establishment of design requirements, each SSC within the CM program should be

assigned a unique identifier, if one has not already been assigned. Unique identifiers that incorporate

system designators, component type, and numbers (e.g., SW-MOV-91) are more useful than strictly

numeric identifiers (e.g., 1357111317). The component identifiers should correspond to the labeling of

equipment for physical configuration. Unique identifiers and equipment labels are important for helping

maintain the CM program basic relationships and for supporting equipment operations. Operational

aspects of equipment designation and labeling are discussed in DOE 5480.19, Conduct of Operations

Requirements for DOE Facilities.

A database owner should be assigned, with roles and responsibilities established. As most of the

information is design information, the design authority is a likely choice. As such, the design authority

would be the focal point for resolving discrepancies and updating the database. Other organizations

should use the CM equipment database as their primary source for SSC design information.

Information necessary to complete certain facility document reference fields will likely come from

personnel coordinating implementation of the document control program element. The purpose of

these facility document references is to support identification of the affected documents when design

changes are made. The design authority can be expected to complete the document references that

relate to design information -- either design requirements or design basis. However, other organizations

will be assigned ownership of other documents important to configuration management (e.g., as-built

drawings; operations, maintenance, and testing procedures; SARs and TSRS). A central document

control organization may support completion of the affected database fields by coordinating database

input for nondesign documents and ensuring the ongoing integrity of that information.

2.2.1.6 Design Reconstitution Interface

The DR adjunct program, if pursued, contributes to the Best Available Design Information. The verified

and validated results of these efforts should be entered into the CM equipment database. Further, these

results should be reviewed for their impact on system and component grading while they are being

entered into the database. If design reconstitution is necessary, certain DR program actions, such as the

formal review of on-hand design documents, should be considered for prompt initiation to support

development of the design requirements element. For major design changes, it may also be desirable

to accelerate design reconstitution on selected systems and components. Implementation guidance for

design reconstitution is provided in Chapter 3.
