About This Item
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 electric motor qualification. This standard also provides guidance for qualification of refurbished motors and insulation systems for motor rewinds.
Abstract
Revision Standard - Active - Draft.
It is required that Class 1E motors, with their interfaces, 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. This standard addresses the qualification portion of the program. It discusses the requirement for maintenance, repair, and surveillance of motors to maintain qualification of motors throughout their service life but does not provide detailed guidance about how these programmatic items must be implemented and maintained. The qualification requirements of this standard, when met, demonstrate and document the ability of the motor and/or insulation system to perform its safety function(s) under specified service conditions.
