"The purpose of this notification is to retract a previous report made on January 7, 2020, at 1909 EST (EN#54465). A subsequent evaluation determined that the Bravo train chiller, which was running at the time of the event, would be able to perform its safety function and was operable at the time of the event. Therefore, there was no loss of safety function.

"The NRC Senior Resident Inspector has been notified."

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE DISCONNECT

The following was received from the Texas Department of State Health Services (the Agency) via email:

"On January 16, 2020, the Agency was notified by a licensee of a source disconnect event. The licensee stated that on January 15, 2020, a crew using a QSA Spec-150 camera with 76 Curies of iridium-192 were unable to retract the source back into the camera. The source was recovered and returned to the shielded position. The licensee suspects that the source was not properly connected to the drive cable, allowing the source to be pushed inside the guide tube but unable to retract it. The licensee stated that the individuals that performed the recovery received 50 mR to 60 mR of exposure, and that no overexposures are suspected as a result of the event. Investigation is ongoing. Additional information will be provided as it is received in accordance with SA-300."
