| Title | Agreement State Report - Stuck / Broken Shutter |
| Event Description | The following information was received via email:
On September 22, 2017, the licensee informed the Department [PA DEP Bureau of Radiation Protection] of a failure of a collimator block. This event is reportable per 10 CFR 30.50(b)(2). On August 25, 2017, the licensee identified a failure of the collimator block attached to the shutter assembly on one of its Thermo Measure Tech Model 5204 gauges containing 4 curies of Cesium-137. The gauge was immediately removed from service. A licensed service provider was contacted and the broken shutter mechanism was removed and replaced with a spare. The shutter mechanism was then tested and confirmed as operating properly. Survey results indicated no abnormal amounts of radiation in the area before or after the repair work. All regulatory precautions were taken and no overexposures occurred. The cause of the event was equipment failure. The Department will perform a reactive inspection. A service provider has already corrected the problem. More information will be provided upon receipt. PA Event Report ID No.: PA170013 |
