Configuration Management. An integrated management program that establishes consistency among

design requirements, physical configuration, and facility documentation, and maintains this

consistency throughout the life of the facility as changes occur. The CM program consists of CM

functions associated with the following program elements: program management, design

requirements, document control, change control, and assessments. The CM program also includes

design reconstitution and material condition and aging management as adjunct programs.

Design Authority. The organization responsible for establishing the design requirements and ensuring

that design output documents appropriately and accurately reflect the design basis. The design

authority is responsible for design control and ultimate technical adequacy of the engineering design

process. These responsibilities are applicable whether the process is conducted fully in-house,

partially contracted to outside organizations, or fully contracted to outside organizations.

Design Basis. Design basis consists of the design inputs, the design constraints, and the design

analysis and calculations. It includes topical areas such as seismic qualification, fire protection,

and safe shutdown. The design basis encompasses consideration of such factors as facility

availability, facility efficiency, costs, and maintainability, and that subset that relates to safety and

the authorization basis. The design basis explains why a design requirement has been specified in

a particular manner or as a particular value.

Design Documents. Those documents that define either the design requirements or the design basis of

the facility. Design documents include design specifications, design change packages, design

drawings, design analysis, setpoint calculations, summary design documents, correspondence

with DOE that provides design commitments, and other documents that define the facility design.

Design Information. The combination of design requirements and design basis information associated

with the design process, consisting of design inputs, design constraints, design analysis and

calculations, and design outputs.

Design Information Summary. A summary design document, organized by system or topical area, that

provides both the associated design requirements and their design basis.

Design Reconstitution. An adjunct program to the CM program that accomplishes the one-time effort

of identifying, retrieving, extracting, evaluating, verifying, validating, and regenerating missing

critical design requirements and basis. Design reconstitution encompasses the following

functions: developing associated program plans and procedures; identifying and retrieving design

information from identified source documents; evaluating, verifying, and validating the design

information; resolving discrepancies; regenerating missing critical design information; and

preparing and issuing Design Information Summaries.

Design Requirements. Those engineering requirements reflected in design output documents (such as

drawings and specifications) that define the functions, capabilities, capacities, physical sizes and

dimensions, limits and setpoints, etc. specified by design engineering for a structure, system, and

component. The design requirements provide the results of the design process.

Design Requirements Element. A CM program element that encompasses the following functions:

establishing and maintaining the facility design requirements, establishing system and process

boundaries , assigning structures, systems, and components (SSCs) grades based on the associated

design requirements, identifying the specific list of SSCs for inclusion in the CM program, and

establishing and maintaining the design basis for the design requirements.

Discrepancy. Those open items that are determined to have safety significance.
