Title	Agreement State Report - Fixed Gauge Shutter Mechanism Failure
Event Description	The following information was provided by the State of Iowa via email: On 1/6/2014 the RSO for MidAmerican Energy Company (Louisa Generating Station), License # 0040-1-70-FG, informed IDPH [Iowa Department of Public Health] that a shutter for a fixed gauge (Texas Nuclear, Model # 5192, s/n B-2723, Source Model # 57157C, containing < 50 mCi of Cs-137) vibrated out of its bracket. This event occurred on 1/4/2014 at approximately 0730 [CST]. The fixed gauge is located on a coal hopper and used for level indication. At the time of the incident the plant is online and the hopper is in use. The fixed gauge is located approximately 50 feet from the catwalk. Since the facility is online, the hopper is in use and no work can occur inside hopper, there is no exposure pathway for any individuals. The licensee has informed all of their employees that no work will be allowed in the hopper until the shutter has been repaired/reinstalled. The licensee has contacted their fixed gauge service provider (RM Wester) to perform repairs/modifications to the fixed gauge so there is no reoccurrence of this event. They are scheduled to be onsite 1/8/2014. IDPH considers this event closed. Item No.: IA140001
