| Title | Agreement State Report - Stuck Shutter on Density Gauge |
| Event Description | The following information was provided by the State of Arkansas via email:
During an on-site inspection on September 19, 2012, the licensee stated that a Berthold Model 7440, density gauge was in storage and that the shutter was not operating (stuck open). The gauge is serial number 2718 and contains 50 millicuries of Cesium-137. On or about March 30, 2009 the licensee was preparing to replace this gauge. While preparing to remove the gauge from service, it was determined that the shutter would not close. The gauge was removed from service, under the direction of the Radiation Safety Officer (RSO), and placed in a secure storage location by the RSO. The gauge is contained in a metal storage locker, facing down toward a concrete slab. In accordance with RH-1502.f.2 (10 CFR 30.50(b)(2) the stuck shutter should have been reported to the State of Arkansas within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. With the manufacturer no longer being in business, the RSO contacted another gauge service company for assistance. The service company indicated they could supply a shielded container to ship the gauge to their facility. At this time, the gauge is still in storage at the licensee's facility. The State of Arkansas is awaiting a written report from the licensee and final disposition information for the gauge. The State's event number is AR-2012-010.
The following updates and closes Event 48330. The licensee provided a letter dated May 6, 2013 stating that the cause of the shutter malfunction was determined to be the harsh environmental conditions the gauge had been subjected to. This letter also documented the receipt/disposal of the gauge [by Thermo MeasureTech]. The Department [Arkansas Department of Health] considers this event to be closed. Notified R4DO (Vasquez) and FSME Events Resource. |
