Work-in-progress report on maintenance good practices for motors in nuclear power generating stations - Part 2

This paper is part of a work-in-progress report which represents work being performed by an IEEE working group. Motor maintenance is addressed by a variety of industry standards, utility procedures and manufacturer's instructions, as well as by recently published assessments of nuclear and non-nuclear operating experience and motor reliability data. This experience supports the premise that motor failure rates are in large part related to application stress factors such as operating time, environmental factors and vibration. In this part, a method for prioritizing motor maintenance based on application stresses experienced by the motors is presented
