|IEEE Program Manager|
This standard applies to the Class 1E portions of the following systems and equipment in single-unit and multiunit nuclear power generating stations: -- AC power systems -- DC power systems -- Instrumentation and control (I&C) power systems This standard does not apply to the preferred power supply; the unit generators and their buses; generator breaker; step-up, auxiliary, and start-up transformers; connections to the station switchyard; switchyard; transmission lines; and the transmission network (see Figure 2 and Figure 3).
Class 1E portions of ac and dc power systems and I&C power systems in single-unit and multiunit nuclear power generating stations are covered in this standard. The provision of criteria for the determination of Class 1E power system design features, criteria for sharing Class 1E power systems in multiunit stations, the requirements for their testing and surveillance, and the requirements for documentation of the Class 1E power system is the intent of this standard.
