Abstract

The minimum acceptable requirements for the performance of reliability analyses for safety systems when used to address the reliability considerations discussed in industry standards and guidelines are set forth in this standard. The requirement that a reliability analysis be performed does not originate with this standard. However, when reliability analysis is used to demonstrate compliance with reliability requirements, this standard describes an acceptable response to the requirements.

Scope

This standard sets forth the acceptable and minimum requirements for the performance of reliability analyses for safety systems when used to address the reliability considerations discussed in industry standards and guidelines. The methods of this standard may also be applied to other systems, including the interactions, if any, between safety and non-safety systems. The requirements should be applied during the phases of design, fabrication, testing, maintenance, and repair of systems and components in nuclear power generating stations and other nuclear facilities. The timing of the analysis depends upon the purpose for which the analysis is performed. This standard applies to the facility owner and other organizations responsible for the activities previously stated.

Purpose

The purpose of this standard is to provide uniform, minimum, acceptable requirements for the performance of reliability analyses for safety systems found in nuclear facilities, but not to define the need for an analysis. The need for reliability analysis has been identified in other standards (e.g., IEEE Std 379 [B8], which describes the application of the single-failure criterion). IEEE Std 352™ provides guidance in the application and use of reliability techniques referred to in this standard.
