| ENS 48155 | 3 August 2012 12:03:00 | The following was received from the State of Arkansas via email: On August 3, 2012, a licensee notified the Department (Arkansas Department of Health, Radioactive Materials) that the shutter mechanism on a RONAN Model# SA1-F37 gauge (SN# 6481GQ), mounted at the apex of a mixing bin, was stuck in the open position. This was discovered during routine maintenance. Since the shutter is in the open position and does not pose an immediate safety risk, the plant continues to operate. The Department was told that even though the gauge is only accessible via man-lift, the gauge has been tagged with a caution sign. The facility has sent email notifications to all personnel as well as posting notices in the plant. The gauge contains 100 mCi of Cs-137. The facility has contacted the manufacturer and the Department will make an onsite visit to coincide with the repair. Further information will be provided as it is obtained. Arkansas Incident # AR-2012-005
On 8/9/12, a RONAN technician performed repairs on a RONAN Model SA1-F37, SN# 6481GQ fixed gauge at the Del-Tin facility in El Dorado, Arkansas to correct a stuck shutter. The device was removed from its mounting, disassembled, cleaned, reassembled and remounted. The shutter is now functional. A wipe test showed no leakage. The root cause was found to be a dry rotted seal that allowed moisture and debris into the mechanism. The Department considers this event closed. Notified R4DO (Proulx) and E-mail to FSME Event Resource. |
| ENS 45538 | 3 December 2009 15:18:00 | The following report was provided by the Arkansas Department of Health via facsimile: On October 26, 2009, during a routine inspection of Desert Industrial X-Ray, ARK-1010-3320, in Beebe AR it was discovered that an INC IR-100 exposure device (SN#4520, Source Model#32, SN#N478, IR-192, 26 Ci) had failed to retract the source to the fully shielded position. The failure to retract had occurred on June 16, 2009. The Radiation Safety Officer for the location was properly trained and had to disassemble and clean the locking mechanism in order to retract the source to the fully shielded position. INC informed Desert Industrial X-Ray that this failure to retract occurs when the exposure devices are getting dirty. The licensee reports that there have been no further problems with this device. Desert Industrial X-Ray personnel reported no unusual survey readings, and no personnel exposures occurred during this incident. The Department ( Arkansas Department of Health) has concluded that the root cause of this incident is improper maintenance of the INC IR-100 exposure device. The licensee has implemented corrective action by introducing an enhanced maintenance program. The Department considers this incident to be closed. See similar report EN#45539. |
