Configuration Management

Installation package

Post-modification testing documentation

Change traveler. A form used to transmit the change control package.

Comprehensive search. A process through which broad spectrums of documents that may contain design

information are identified, retrieved, and evaluated. Key steps involve locating and screening documents

that may contain design information and reviewing them to extract design information.

Cognizant system engineer. The engineer assigned technical responsibility for a particular system, who

coordinates technical activities related to the assigned system. The Cognizant System Engineer has

technical understanding of the system requirements design, operation, testing and maintenance. The

Cognizant System Engineer ensures that relevant documents, such as system design descriptions, technical

drawings, diagrams, lists, and procedures for surveillance, testing and maintenance are complete, accurate,

and up to date. The Cognizant System Engineer may also keep vendor technical information and

appropriate files concerning system history of repairs, modifications, operational problems, and other

unique conditions or circumstances. Equivalent terms include: cognizant engineer, system engineer,

system specialist, and subject matter expert.

Configuration. Configuration is the combination of the physical, functional, and operational characteristics

of the structures, systems, and components (SSCs) or parts of the existing facility, operation, or activity.

(NQA-1)

Configuration baseline. A configuration baseline consists of all approved documents that represent the

definition of the product at a specific point. (ISO 10007:1995(E))

Configuration control board or configuration board. The Configuration Control Board is a collection of

technical, management, and administrative experts assigned the authority and responsibility to make

decisions on the configuration and its management.

Configuration management (CM). Configuration management is a disciplined process that involves both

management and technical direction to establish and document the design requirements and the physical

configuration of the nuclear facility and to ensure that they remain consistent with each other and the

documentation.

Configuration management structures, systems and components (CM SSCs). CM SSCs are the set of

structures, systems, and components that are managed under the configuration management process when

changes are proposed and implemented. At a minimum, the CM SSCs include the safety SSCs as identified

in the documented safety analysis, the Vital Safety System SSCs and other defense-in-depth SSCs. They

may also include SSCs related to:

Environmental safety

High cost

Critical mission capability

Critical software capability

Adjacent SSCs that could affect safety.

Defense-in-depth. Defense-in-depth describes the multiple equipment and administrative features that

together are relied upon to provide preventive or mitigative functions to a degree proportional to the

potential hazard.

Design assessments. Design assessments are performed to ensure that design documents have been

updated to reflect changes and accurately reflect the physical configuration of the nuclear facility.
