Title	Agreement State Report - Malfunction of Irradiator Source Drive Mechanism
Event Description	The following information was received from the Texas Dept of Health Services Investigation Unit Radiation Branch via email: On October 12, 2011, at 1552 hours0.018 days <br />0.431 hours <br />0.00257 weeks <br />5.90536e-4 months <br /> CDT, the Agency was notified by the licensee's Radiation Safety Officer (RSO) that there had been a malfunction identified with [a self contained] irradiator, at the licensee's facility in Houston, Texas. The source was, and had been, in the fully shielded position and therefore did not present a risk of exposure to any individual. The owner/operator within the facility reported to the RSO's staff that the compressor failed on Friday, October 7, 2011, and they were going to get it repaired or replaced. While working to replace/repair the compressor, it was determined that the problem was not the compressor. The licensee was able to open and close the door to the irradiation chamber and apparently make up all the interlocks, but the source failed to move. Finally, it was determined on Wednesday, October 12th at approximately 1430 hrs that the source drive mechanism was failing to move the source. The owner/operator has been in contact with Shepherd to make arrangements for repair. More information will be provided as it is obtained. The irradiator has been posted as out of service. The source is properly shielded as shown by dose rate surveys conducted in the room. Texas Incident Number: I-8892
