Basic principles for design qualification of safety systems equipment used in nuclear power generating stations are provided. Specification criteria, the development of a qualification program, and documentation are addressed. All types of safety systems equipment--mechanical and instrumentation as well as electrical--are covered. Principles and procedures for preparing specific safety systems equipment standards are established.

This standard provides the basic principles for design qualification of safety systems equipment used in nuclear power generating stations.

The purpose of this standard is to provide basic principles and guidance to demonstrate the design qualification of safety systems equipment. Design qualification is intended to confirm the adequacy of the equipment design to perform its safety functions over the expected range of normal, abnormal, design-basis event, post design-basis event, and in-service test conditions.
