Scope: This standard specifies the nuclear power plant: a) The main design criteria and design measures of the safety-level power system (these criteria and measures can make the safety-level power system meet its functional requirements under the conditions caused by the applicable design basis events); b) Safety c) Criteria for multi-unit nuclear power plants sharing safety-rated power systems. This standard is applicable to safety-level parts of the following systems and equipment in single-unit and multi-unit nuclear power plants: a) AC power system; b) DC power system; c) instrumentation and control power system. These systems include the items listed in Table 1. This standard does not apply to priority power sources, generators and their buses of units, generator circuit breakers, main (i.e. step-up) transformers, service (i.e. auxiliary) transformers, starting (i.e. standby) Connection lines, switchyards, transmission lines and transmission networks (see Figure 1).
