Description / Abstract:
This standard covers the application of the single-failure
criterion to the electrical power, instrumentation, and control
portions of nuclear power generating station safety systems.
Purpose
The purpose of this standard is to interpret and provide
guidance in the application of the single-failure criterion,
discuss failures, and present an acceptable method of
single-failure analysis. It is not the function of this standard to
identify where the single-failure criterion is to be applied or to
force compliance on any system; however, in those cases where the
single-failure criterion has been invoked, this standard
establishes the requirements for its application.
This standard shall be used to establish conformance with the
requirements of IEEE Std 603™1 and the single-failure criterion as
stated in that standard.
