Title	Agreement State - Stuck Shutter
Event Description	The following information was provided by the The Washington State Department of Health via email: The shutter on a fixed nuclear gauge [a Vega Americas Corp. Model No. SH-F1 gauge containing 53 millicuries of Cs-137] was unable to be closed when licensee staff attempted to lock it out. Licensee staff consulted with the manufacturer and, per the manufacturer's recommendation, installed four inches of steel plates in front of the fixed nuclear gauge to shield it. After installation of the steel plates, radiation levels were 0.2 mR/hour. The licensee is planning to replace the entire fixed nuclear gauge, per the manufacturer's recommendation, as the manufacturer has previously replaced the shutter on this gauge. The steel plates will remain installed until the fixed nuclear gauge is replaced. The Washington State Department of Health will gather additional information about this event and will submit an updated event report. An investigation may be conducted. WA Event Number: WA-23-031
