| Title | Potential Defect in Cuttler Hammer Circuit Breakers |
| Event Description | DHP-VR350, 1200A, circuit breakers were manufactured by Cutler-Hammer Inc., commercially dedicated for Class 1E applications by Westinghouse and shipped to the Columbia Generating Station. During installation acceptance testing, one breaker charging motor failed to charge. Columbia Generating personal performed, a 100% inspection on all 16 breakers with safety-related functions. There was a loose screw associated with this position switch found in seven of these breakers.
Westinghouse will be issuing a Nuclear Safety Advisory Letter (NSAL) to all PWR and BWR plants informing them of this issue so they can determine applicability to their plant. |
