Standard for Design and Installation of Cable Systems for Class 1E Circuits in Nuclear Power Generating Stations
|Publication Date:||5 December 2018|
This standard provides requirements for the design and installation of safety related electrical cable systems, including associated circuits, in nuclear power generating stations. Also provided are requirements for the design and installation of those non-safety related cable systems that may affect the function of safety related systems.
NOTE-The term "associated" circuits is not repeated throughout the text; however, all requirements for the design and installation of cable systems for Class lE circuits apply equally to associated circuits unless it can be shown by test or analysis that the associated circuits cannot affect the performance of the Class lE circuits.3
The purpose of this standard is to identify existing standards and to establish requirements pertaining to safetyrelated cable systems in nuclear power generating stations. Solutions are recommended for areas of concern such as fire protection, raceways, separation, cable performance requirements, and installation acceptance testing and documentation.4
3Notes in text, tables, and figures of a standard are given for information only and do not contain requirements needed to implement this standard.
4Other solutions may also be acceptable based on an engineering review of the specifics involving the installation. Each situation should be reviewed and examined on its own merits.
