The following information was provided by the
New Jersey Department of Environmental Protection via email:
While performing routine 6-month fixed gauge shutter checks, the licensee became aware of a shutter that was stuck partially open. The fixed gauge is located 20 feet above a platform and only accessible to licensee staff via scaffolding. No member of the public has 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. They have scheduled them to assess this situation and make any necessary repairs.
Gauge information: Cs-137 sealed source in Ohmart/Vega holder SH-F2 (s/n 0361CG), max activity 300 mCi. Leak test conducted October 2023. No detectable leakage.
