Maintenance Good Practices for Nuclear Power Plant Electrical Equipment

This paper is Part 1 of a work-in-progress report which represents work being performed by an IEEE working group. Motor maintenance is addreessed by a variety of industry standards, utility procedures and manufacturer instructions, as well as by recently published assessments of nuclear and non-nuclear operating experience and motor reliability data. Nuclear utilities must select effective maintenance practices from these sources, while giving due consideration to their own particular experience. In this paper, good practices for preventive maintenance of motors are recommended which address the most frequent causes of motor failures. Due to the large number of critical motors installed in a nuclear generating station, the problem of prioritizing motors for preventive maintenance has been addressed in Part 2, a companion paper.
