On December 2, 2013, the Agency [Texas Department of State Health Services] received information from the licensee that on November 29, 2013, at 1940 hrs. CST, the drive mechanism on a Nordion JS-8900 (continuous) pool-type irradiator had failed to completely lower one of the source racks into the fully safe position at the bottom of the pool. Source rack one was completely lowered into the pool by venting the source hoist air cylinder. The licensee reported that the preliminary root cause seems to be debris in the air system which caused the solenoid to get stuck and prevented the source hoist piston from completely lowering the source rack. The solenoid valve spools were replaced, the source cycled several times, and normal operation continued. There were no exposures as a result of this incident. An investigation into this event is ongoing. Further information will be provided as it is obtained in accordance with SA-300. | On December 2, 2013, the Agency [Texas Department of State Health Services] received information from the licensee that on November 29, 2013, at 1940 hrs.
