AGREEMENT STATE REPORT - UNABLE TO DETERMINE IF SOURCE IN SHIELDED POSITION ON LEVEL INDICATOR The following information was received via E-mail: On August 26, 2020, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that while making preparations for the coming hurricane, the position of the source rod on a Tracerco, Model T-218-160032 [used for level indication] could not be confirmed. The source rod contains 10 cesium-137 sources of 10 milliCuries each (original activity.) The RSO stated when they return the sources to the shielded position, the control system does indicate the sources are shielded as indicated by a light change on the system console. When the licensee attempted to shield the sources on this day, the light did not change to indicate the sources were shielded. The gauge source rod is operated manually. They tried it a couple of times, but the light still did not change. A survey was performed on the outside of the vessel. The RSO stated there wasn't enough change in dose rate readings with shutter in the open and closed positions to determine whether the sources were shielded based on survey. The RSO stated it may be that the sources are not moving, or it may be that there is an issue within the control system causing the light not to change. They cannot determine at this time which problem is occurring. The RSO is contacting the manufacturer to send someone out after the hurricane. There is no risk of exposure. The RSO stated they will update the Agency once the manufacturer determines the problem. Additional information will be provided as it is received in accordance with SA-300. Texas Incident Number: 9787
The following information was received via e-mail: On September 1, 2020, the licensee notified the Agency (Texas DSHS) that on August 31, 2020, a service company came onsite to investigate the shutter problem they had reported, and identified that there was no mechanical issue with the shutter. The problem they had was a failure of the output signal to indicate source position. The source rod was functioning normally. Based on this information, the Agency is retracting this event. Notified R4DO (Deese) and NMSS Events (email). |
