Full Description

Scope

This standard establishes criteria for qualification of alternating current Class 1E motors, located in mild and harsh environments in nuclear power generating stations in order to demonstrate their ability to perform their intended safety functions under all required conditions.

Purpose

The purpose of this standard is to provide direction for the implementation of the requirements of IEC/IEEE 60780-323:2016 as they apply to the specific features of alternating current Class 1E electric motor qualification. This standard also provides direction for the qualification of refurbished motors and insulation systems for motor rewinds.

Abstract

Revision Standard - Active. Class 1E motors, along with their interfaces, are required to meet or exceed the specified performance requirements throughout their service life. This is accomplished through a program that includes, but is not limited to, design, qualification, production quality control, shipping, storage, installation, operation, maintenance, periodic testing, and surveillance. The qualification portion of the program is addressed by this standard. The requirement for maintenance, repair, and surveillance of motors to maintain their qualification throughout their service life is discussed, but detailed guidance on how these programmatic items must be implemented and maintained is not provided. When the qualification requirements of this standard are met, the ability of the motor and/or insulation system to perform its safety function(s) under specified service conditions is demonstrated and documented.
