Configuration Management

completed prior to construction the design is "frozen." This is an opportune time to

initiate the configuration management process to control future changes.

DOE G 420.1-1 states:

Document and change control for project design documents and supporting

documentation must be provided by the design activity during the design. By the start of

construction, document and change control must be provided by an appropriate QA

configuration management program. Subsequent changes to project design and

supporting documents must be made by means of a formal change control program in

accordance with 10 CFR 830.120 [10 CFR 830, Appendix A].

For new construction, (i.e., new facilities and major modifications to existing facilities),

the design requirements must be identified and documented as part of the design process

and incorporated into a formal configuration management process before start of

construction. The contract with the architect engineer and/or construction contractor

should specify the expected actions related to configuration management for the design

and construction activities, as well as for construction turnover to the operating

contractor.

3.1.2 Existing Facilities and Activities

The contractor should have identified the design requirements for safety systems,

structures, and components (SSCs) for existing, hazard category 1, 2, and 3 nuclear

facilities during the development of the documented safety analysis (DSA) to meet

10 CFR Part 830, Subpart B. For facilities that lack thorough documentation of the

design basis, or for SSCs other than safety SSCs, the requirements for previously

installed SSCs may not be documented or available. In these cases, it may not make

sense from a cost versus benefit perspective to immediately reconstruct the design

requirements.

The contractor should document the new or revised design requirements as maintenance

and modifications are performed at the facility or activity. In these cases, the contractor

must:

ensure that the DSA demonstrates that the functional requirements for the safety

SSCs are sufficient, and

validate that the safety SSCs will perform their safety functions as assumed in the

analysis.

If the information is not sufficient to adequately document the configuration management

baseline to validate proper operation of the safety SSCs, then the contractor should

determine if additional action is necessary to complete the available information on the

design requirements for the nuclear activity so that changes can be adequately assessed.
