FIRST INTERIM REPORT Description of Deficiency During performance of a functional test on stationary air compressor motor 1RJ-EMOT-002-B, the motor failed during an attempted restart.
This is the second instance of this type of failure on this type and size motor (nonconformance report 1942).
Bellefonte is the only TVA nuclear plant to use this size motor and system configuration.
Interim Progress The stator of the motor is to be returned to the vendor for rework.
TVA's Division of Engineering Design has been requested to evaluate the failure and determine possible cause and actions required to prevent recurrence.
