Description / Abstract:
This standard contains the requirements for the design,
installation, and qualification of raceway systems for Class 1E
circuits external to electric equipment and components for nuclear
power generating stations. Because aging and radiation have no
known detrimental effects on metallic raceway systems and because
nonmetallic raceway systems are limited to underground or embedded
applications, aging and radiation are not considered in this
standard. The embedments or structural members to which a support
is attached are beyond the scope of this standard.
Purpose
The purpose of this standard is to provide criteria for the
minimum requirements in the selection, design, installation, and
qualification of raceway systems for Class 1E circuits for nuclear
power generating stations. It also prescribes methods for the
structural qualification of raceway systems for Class 1E
circuits.
