1 Scope
This standard specifies general principles and requirements for the application of the single failure criterion to the electrical power, instrumentation and control portions of safety systems in nuclear power plant.
This standard interprets and provide guidance in the application of the single failure criterion, discuss failures, and present an acceptable method of single-failure analysis.
This standard not to identify where the single failure criterion is to be applied on any system.
This standard is applicable to safety systems in nuclear power plant.
This standard shall be used to establish conformance with the requirements of GB 13284.1-2008 and the single failure criterion as specified in that standard.
