The following information was provided by the
New Jersey Department of Environmental Protection via email:
On December 5, 2024, the licensee became aware of a shutter that could not fully close but was able to return to the fully open, operative position. The shutter failure was identified while performing a routine six-month fixed gauge shutter check. The fixed gauge is located eight feet above a walking platform which is only accessible to licensee staff via ladder, scaffolding or other means. No members of the public have access to this location.
The shutter is currently in its normal, open position. No maintenance activities are scheduled which would require closure of the shutter.
The licensee has a contract with the manufacturer and has scheduled them to assess this situation and make any necessary repairs.
The shutter holder contains a Cs-137 sealed source (model A-2102) with maximum activity of 300 mCi.
This event is reportable under 10 CFR 30.50(b)(2) [NJAC 7:28-51.1]

Model number: SH-F2
