scope:

This standard sets forth the minimum acceptable requirements for the performance of reliability analyses when used to address the reliability considerations discussed in the standards listed below for safety-related systems.

This standard applies to all systems, or portions of systems, for which reliability considerations are discussed in the following IEEE Standards:

1) IEEE Std 279-1971 (ANSI N42.7-1972 ), Criteria for Protection Systems for Nuclear Power Generating Stations.

2) IEEE Std 308-1974, Standard Criteria for Class lE Power Systems for Nuclear Power Generating Stations.

3) IEEE Std 338-1975, IEEE Criteria for the Periodic Testing of Nuclear Power Generating Station Class lE Power and Protection Systems.

4) IEEE Std 379-1972 (ANSI N41.2-1972 ), Guide for the Application of the Single-Failure Criterion to Nuclear Power Generating Station Protection Systems.

NOTE - Revisions to the above standards may, or may not, result in changes to requirements for reliability analyses to be performed. These references are cited because they represent current requirements.

The methods of this standard may also be applied to other systems including the interactions, if any, between safetyrelated and non-safety-related system.

The requirements can be applied during the phases of design, fabrication, testing, maintenance, and repair of systems and components in nuclear-power plants. The timing of the analysis depends upon the purpose for which the analysis is performed. This standard applies to the plant owner and other organizations responsible for the activities stated above.
