Taxonomy Comparison PDF Print E-mail

fig_1_equilibrium_model

The Configuration Management taxonomy has been designed to provide a hierarchical connection between requirements and individual structures, systems, and components. To do so, it was necessary to make significant changes to the existing taxonomy previously laid out in NEI 97-04 [1]. The taxonomy remains consistent with the Configuration Management Equilibrium model described in INPO AP-929 [2], shown here.

The relationship between the terminology in AP-929, and the new Configuration Management taxonomy is summarized in the following table:

 

Terminology Comparison
INPO Terminology
 CM Taxonomy Terminology
Design Requirements
 Codes & Standards
Regulations and Legal Requirements
Economic and Non-Regulatory Requirements
Design Bases Specifications
SSC Specifications
Facility Configuration Information Supporting Design Information
Design Parameters
Supporting Operating Information
Characteristics of individual structures, systems, and components (SSC)
Physical Configuration The term "Physical Configuration" refers to the actual equipment and materials that comprise the nuclear plant. The term "Physical Configuration" does not refer to the characteristics of the equipment and materials, but to the physical items themselves.
