Full Description

Scope

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 pwoer generating stations. Since aging and radiation have no known detrimental effects upon metallic raceway systems, and since non-metallic raceway systems are limited to underground or embedded applications, these two environmental conditions are not considered in this document. The embedments or structural members to which a support is attached are beyond the scope of this document.

Purpose

It is the intention of the working group to address at least the following areas in this proposed revision of IEEE 628: expand upon the requirements for use of non-metallic raceways in embedded applications, allow use of experience data as a means of qualifying the raceway system, evaluate impact of later revisions of standards referenced in IEEE 628: incorporate when/if possible. The purpose of the standard will remain as is in IEEE 628-1987 which 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.
