Revision Standard - Superseded.
This standard applies to those parts of the electric systems in stationery single-unit and multi-unit land-based nuclear power generating stations that provide electric power to the Class IE electric equipment. The electric systems included are comprised of the following interrelated systems" (1) alternating-current power systems, (2) direct-current power systems, (3) vital instrumentation and control power systems. These systems consist of power supplies (e.g., connections to the station switchyard, stand-by generators, batteries), distribution equipment and components (e.g, transformers, switchgear, bus cable, battery chargers, inverters), and instrumentation and controls (e.g., relays, meters, switches, control devices). This standard does not apply to the unit generator(s) and their buses, step-up and auxiliary transformers, switchyard, transmission lines and transmission network.
The purpose of this standard is to provide: (1) the principal design criteria and the design features of the Class IE electric systems that enable the systems to meet their functional requirement under the conditions produced by the design basis events. (2) The minimum operational conditions for the Class IE electric systems under which the station will be permitted to perate, (3) The surveillance requirements for the Class IE electric systems.
