Configuration Management
Chapter 6 provides objectives for the documentation of design information.

Using System Design Descriptions
A recommended approach to documenting design requirements and providing a link
between engineering design documents, the safety basis, and implementing procedures is
to develop system design descriptions (SDDs). SDDs identify requirements, explain why
those requirements exist (e.g., provides the bases for the requirements), and describe the
features of the system design provided to meet those requirements. SDDs can be used to
promote consistency among the engineering requirements, the actual installed physical
configuration, and the associated documentation. SDDs help facility personnel
understand system functions and requirements. In addition to providing a system
drawing and written description, they include discussions of functional process
requirements, system and component design requirements, system interfaces and
interlocks, setpoints, and design requirements related to operations, maintenance, and
testing, detailed design and operating descriptions, diagrams, and load lists. Information
on the use and specific content of SDDs is provided in DOE-STD-3024-98, Content of
System Design Descriptions.
3.8
Establishing Equipment Databases
Contractors must develop configuration management equipment databases that cross-
reference SSCs with their design requirements, design basis, and associated documents.
These databases will be the primary information source for design requirements.
Contractors should use the best available design information to fill the database fields.
The configuration management equipment database can be used to contain and correlate
key information, such as:
system designators;
component designators;
component descriptive information such as type, manufacturer, model, and size;
grades/Priority/Classification;
design requirements or references to design requirements;
design basis references;
design topical area references (e.g., seismic, environmental qualification, fire
protection);
range of acceptable setpoints;
facility document references (e.g., drawings, procedures, DSAs);
technical Safety Requirement (TSR) references;
maintenance equipment lists (MELs);
other desired system and component information;
