23、ndard for the Design and Installation of Cable Systems for Class 1E Circuits in Nuclear Power Generating Stations 1. Overview 1.1 Scope This standard provides direction for the design and installation of safety related electrical cable systems, including associated circuits, in nuclear power generat
24、ing stations. Also provided is guidance for the design and installation of those nonsafety related cable systems that may affect the function of safety related systems. NOTEThe term associated circuits is not repeated throughout the text; however, all requirements for the design and installation of
25、cable systems for Class 1E circuits shall 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 1E circuits. 1.2 Purpose The purpose of this standard is to identify existing standards and to establish r
26、equirements 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.12.

Cable, Field Splice, and Connection Qualification This clause establishes qualification requirements that shall be utilized in specifying cables, field splices
43、, and connections of cable systems for Class 1E circuits. 4.1 Requirements a) Cables, field splices, and connections shall have a qualified life for all service conditions that are postulated for the areas where they are to be used and shall be qualified in accordance with IEEE Std 323, IEEE Std 383
44、 and IEEE Std 572. b) All cables shall pass the vertical tray flame test described in IEEE Std 1202, except that switchboard wires, coaxial, twin axial and triaxial cables shall, as a minimum, pass the UL VW-1 flame test. 8NEMA publications are available from National Electrical Manufacturers Associ

Conductor Sizing This clause establishes cable conductor sizing requirements for various types of cable installations
47、for Class 1E circuits. Power cables shall be sized in accordance with IEEE Std 835 and NEMA WC 51-2003/ICEA P-54-440. Cables shall be sized to carry load current with the following special considerations: a) Unless specific site ambient conditions or the safety analysis of the plant supports other a
48、mbient temperatures, the minimum ambient temperatures used in calculating cable ampacities shall be 30C for buried installations and 40C for exposed installations. Conductor size shall be selected to carry required normal, emergency overload, and short-circuit current without exceeding rated tempera
49、ture of the insulation at the maximum postulated ambient temperature. Temperature extremes under design basis events shall be addressed by the qualification of the cable in accordance with IEEE Std 383. b) Where installed cable along its route is exposed to different conditions (direct buried, sun exposure, exposed conduit, cable penetration fire stops, covered cable trays, wireways, near hot steam lines, etc.) conductor size shall be selected for the limiting condition. c) Selection of conductor size shall also consider voltage
