Configuration Management

Program for DOE Nuclear Facilities, the Cognizant System Engineer has the lead

responsibility for the configuration management of design.

The Cognizant System Engineer must be knowledgeable of the system and the related

safety basis. The Cognizant System Engineer must also retain a working knowledge of

the facility's operation and the existing condition of the system. Consequently, the

Cognizant System Engineer is also responsible for overseeing the configuration of the

assigned system to ensure that it continues to be able to perform its expected functions.

The Cognizant System Engineer should:

be knowledgeable of the system safety functions, requirements, and performance

criteria and their bases;

understand how the system SSCs are designed and how they function to meet the

requirements and performance criteria;

understand system operation;

be knowledgeable of the testing and maintenance necessary to ensure the system

continues to be able to perform its safety functions;

be responsible for ensuring that documents related to the system are complete,

accurate, and up-to-date, including SDDs, technical drawings, diagrams, and

procedures for surveillance, testing, and maintenance;

be appropriately involved in the design, review, and approval of changes

affecting/impacting system design, operation, and maintenance.

Because the Cognizant System Engineers are expected to have a thorough understanding

of system design expectations, operating requirements, and current configuration, the

Cognizant System Engineers should have a major role in identifying the CM SSCs. Each

Cognizant System Engineer should also participate in the identification of the design

requirements for their system and the SSCs within the system. Finally, the Cognizant

System Engineer should participate in the configuration management review of any

changes that are made to the system for which the Cognizant System Engineer has

cognizance responsibility.
