Defining the Scope of CM SSCs


DOE-STD-1073-2003
Configuration Management
One way to do this is by using engineering data recovery techniques. Data recovery
techniques include searching for and reviewing existing files, archived records, and other
sources that might contain the information, and validating the accuracy of the information
before it is used.
If the contractor determines that the data recovery techniques are still not sufficient to
adequately complete the design requirements, the contractor should consider whether the
information should be regenerated (e.g., performing analysis and/or calculations, or
interviewing technical experts who are knowledgeable about the particular equipment or
situation). If the contractor decides to pursue regeneration of the information, it should
take maximum advantage of pertinent existing safety analyses and design information
(i.e., requirements and their bases) that are immediately available or can be retrieved
through reasonable efforts. Appendix D provides general information that may be used
to regenerate documentation. The regeneration process can be expensive and should only
be pursued when it is essential to manage the configuration of the nuclear activity safely
and efficiently.
When changes are performed, the contractor must document the design requirements
associated with the change. By doing this, contractors can incrementally enhance the
information on design requirements in a cost-effective manner.
Once the design requirements are established, the configuration management process
should be used to control changes because recovery of design information at a later date
can be time consuming and costly. Figure 3-2 illustrates the potential sources for
gathering the best available design requirements for SSCs under the configuration
management process, which will be referred to as the CM SSCs throughout this standard.
