IEEE Std 308:2020 pdf download.IEEE Standard Criteria for Class 1E Power Systems for Nuclear Power Generating Stations.
IEEE Std 308 applies to the (‘lass I E portions of the ftllowing systems and equipment in single-unit and multiunit nuclear power generating stations:
Alternating current (ac) power systems
Direct current (dc) power systems
- Instrumentation and control (l&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 ransfijrmers: connections to the station switchyard: switchyard:
transmission lines: and the transmission network (see Figure 2 and Figure 3).
1.2 Purpose
The purpose of this standard is to provide the tbllowing:
The principal design criteria and the design features of Class I E power systems that enable the systems to meet their functional requirements under the conditions produced by the applicable design basis events.
The requirement for tests and surveillance of Class I E power systems.
The criteria for sharing Class I E power systems in multiunit stations.
The requirement tr documentation of Class 1E power systems.
1.3 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard
and from which no deviation is permitted (shall equals is required to).’
The word should indicates that among several possibilities one is recommended as particularly suitable. without mentioning or excluding others: or that a certain course of action is preferred but not necessarily required (should equals is recommended that).
The word mar is used to indicate a course of’ action permissible within the limits of the standard (may equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical. or causal (can equals is able to).
