The
Utah Division of Radiation Control was notified by service personnel on 08/11/2008 at approximately 10:00 a.m. MDST and spoke with the licensee regarding the incident at 5:00 p.m. MDST. The
RSO was attempting to close the shutter of a fixed
gauge on the 'Syn Tower' so that maintenance personnel could work inside the vessel. [Ohmart, model
SH-F1, serial number LS-620]. The device shutter resisted turning when the
RSO attempted to close the
gauge. The
RSO then 'tapped lightly' on the shutter handle with a bolt to get it to turn. It turned slightly and the
RSO put the bolt down to turn the shutter handle by hand. Both of the shutter handle screws sheared off and the shutter could not be closed. An authorized service licensee was able to close the shutter while the
gauge was in place. The
gauge was then removed and taken offsite for repair by an individual licensed to perform these services. The
RSO has completed the manufacturer's
