Title	Part 21 Report - Failure of a Spare Limitorque Actuator Motor
Event Description	On July 31, 2009, [Crystal River Unit 3] personnel performed a video probe inspection of a spare safety-related Limitorque SB-3/SMB-3 actuator motor magnesium rotor and end rings. Visual indications were observed in the outboard end of the motor which were cause for rejection based on specified acceptance criteria. The specific indication was a cracked weld with dislodged metal in the outboard end of the motor. In 2007, the spare safety-related Limitorque SB-3/SMB-3 actuator motor (Motor Serial Number 7497004-001T1AL: Limitorque Part No. R-403-F04-0821) was purchased as safety-related Quality level 1 (QL-1) from AREVA under Purchase Order No. 337566. Limitorque purchased the motor from the Baldor Electric Company, doing business as the Reliance Electric Company, as commercial grade and dedicated the motor to safety related. The above evaluation was completed on August 28, 2009. The FPC director/responsible officer was notified of the above determination on August 31, 2009. The vendor (Limitorque) and the NRC Senior Resident Inspector have been notified of FPC's intent to report this issue under 10CFR21.21. The NRC Resident Inspector has been notified.
