Title	Stuck Irradiator Source
Event Description	The following information was provided by the licensee via telephone and email: At 1000 MST on 3/5/24, a 10,000 Ci Co-60 source (Model 7810) became stuck in the unshielded position during operator training. The irradiator is a J.L. Shepherd, Model SDF-34-M1, panoramic dry-source storage type. Upon determining that the source was stuck, the operator attempted to manipulate the source back into the shielded position using the emergency cable, but it came loose. Site staff have secured the irradiator facility. No personnel exposure occurred, and there are no elevated dose rates outside of the irradiator enclosure. The site has requested manufacturer support to resolve the issue. The NRC Project Manager (OKeefe) has been notified. * * UPDATE ON 4/18/24 AT 1508 EST FROM MAJ RYAN EISWERTH TO ADAM KOZIOL * * * On 3/18/24, authorized users were able to return the source to a shielded position. A post-event inspection was scheduled during the week starting 4/22/24 with the vendor to verify operability of the irradiator. At approximately 1000 MST on 4/18/24, while an authorized user was conducting a performance functional check in preparation for the scheduled inspection, the irradiator source again became stuck in an unshielded position. The irradiator had not been used since the initial report on 3/5/24. No personnel exposure occurred, and there are no elevated dose rates outside of the irradiator enclosure. The site has requested manufacturer support to resolve the issue. Notified R4DO (Young), IRMOC (Crouch), and NMSS Events (email).
