IEEE Criteria for Class IE Electric Systems for Nuclear Power Generating Stations

This Standard (IEEE Std. 308) presents criteria and requirements for the electric systems of nuclear generating stations specifically related to providing protection to the health and safety of the public. These are based on the following. (a) Redundant systems that require electric power are provided to cope with design basis events. (b) The conditions and the availability of the various portions of the systems following a design basis event cannot be predicted exactly. (c) The access to certain equipment following a design basis event may be limited for several months. The Institute of Electrical and Electronics Engineers has developed these criteria to provide guidance in the determination of the design features, minimum conditions of operation, and the surveillance requirements related to the electric power systems of the nuclear facility. Each applicant for a construction permit or an operating license for a nuclear facility in the USA is required to develop these items to comply with the Atomic Energy Commission´s Code of Federal Regulations, Part 50.
