Title	Agreement State Report - Stuck Shutter on Process Gauge
Event Description	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 * * UPDATE VIA E-MAIL FROM ROBERT PEMBERTON TO DONALD NORWOOD ON 8/31/2012 AT 1139 EDT * * * 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.
