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. Design documents 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 reconstitution. An adjunct program to the configuration management process 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.
Discrepancy. As used in this standard, a discrepancy is an inconsistency among the physical configuration,
the design, and the documentation.
Document. Document means recorded information that describes, specifies, reports, certifies, requires, or
provides data or results.
Document control. The act of assuring that documents are reviewed for accuracy, approved for release by
authorized personnel, and distributed to and used at the location where the prescribed activities are
Documented safety analysis (DSA) Documented safety analysis means a documented analysis of the extent
to which a nuclear facility can be operated safely with respect to workers, the public, and the environment,
including a description of the conditions, safe boundaries, and hazard controls that provide the basis for
Environmental design requirements. In the context of the configuration management process, those design
requirements that are necessary to protect the environment, and to satisfy environmental requirements and
permits, as well as other related DOE requirements.
