P690 - IEEE Draft Standard for the Design and Installation of Cable Systems for Class 1E Circuits in Nuclear Power Generating Stations

The purpose of this standard is to identify existing standards and to establish requirements pertaining to safety related 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.This standard provides direction for the design and installation of safety-related electrical cable systems, including associated circuits, in nuclear power generating stations. Also provided is guidance for the design, installation and performance requirements of those non-safety related cable systems that may affect the function of safety related systems. It provides guidance on applications of cable-penetration, fire stops, cable fire breaks, and cable-system enclosures for cable systems for Class 1E circuits.
