Description / Abstract:
This standard covers qualification of Class 1E protective relays
and auxiliaries to be used outside the primary containment in the
nuclear power generating stations. Protective relays and
auxiliaries located inside the primary containment in a nuclear
power generating station present special conditions beyond the
scope of this document.
Purpose
The purpose of this standard is to
a) Define specific qualification methods for Class 1E protective
relays and auxiliaries in accordance with the more general
qualification requirements of IEEE Std 323.
b) Provide guidance in establishing a program for demonstrating
the design adequacy of Class 1E protective relays and auxiliaries
in nuclear power generating stations applications.
