| Title | Improper Application of 440 Vac Rated Motors |
| Description | The inspectors identified a finding of very low safety-significance and associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to ensure the proper application of safety-related 440Vac motors. Specifically, eight440Vac safety-related motors were not suitable for operation at analyzed voltages. This finding was entered into the licensees corrective action program. The finding was more than minor because if left uncorrected it could result in the loss of safety-related 440Vac motors by overstressing of the motor windings through exposure to higher than design rated voltages, and in the failure of motor drive components caused by increased torque produced at the higher voltages. The finding was determined to be of very low safety-significance (Green) because it did not result in a loss of operability. The cause of this finding is related to the cross-cutting aspect in the area of Problem Identification and Resolution, Corrective Action Program, because the licensee did not identify this issue completely, accurately, and in a timely manner. The values were produced in a calculation but the licensee did not identify that they exceeded the acceptance criteria. |
