This recommended practice provides a single source of nuclear power plant system descriptions that, along with related recommended practices concerning unique identification principles and definitions, component function identifiers, and implementation instructions, provide a basis for uniquely identifying systems, structures, and components of light water nuclear power plant projects (electric power generating stations) and related facilities. The system descriptions concentrate on system function and include such internal details as are necessary to clearly support the system function description. They are not intended to serve as design input. Fossil, hyd...

This recommended practice provides a single source of nuclear power plant system descriptions which, along with related recommended practices concerning unique identification principles and definitions, component function identifiers, and implementation instructions, makes up a concept for uniquely identifying systems, structures, and components of light water nuclear power plant projects (electric power generating stations) and related facilities. Fossil, hydro, and other types of power plants are not included in this edition.

The purpose of this series of recommended practices is to present a common language of communication which will permit a user to correlate a system, structure, or component with another organization for the purposes of reporting, comparison, or general communication. It does not require a using organization to change its own internal identification concept, but if the organization chooses to do so it has only to transcode at the interface from their internal language to this common language concept. The user may choose to adopt this concept for internal organizational use. It represents the accumulated practice of the industry assimilated into one set of pra...
