Title	Fire Damaged Fixed Gauges
Event Description	The following information was received from the state of Maryland via email: On October 03, 2022, at about 1300 EDT, the Maryland Department of the Environment, Radiological Health Program (MDE/RHP) was contacted via telephone from the Radiation Safety Officer (RSO) of Brandon Shores, LLC. [The licensee] followed-up by email message on October 04, 2022 at 1342 EDT. The RSO reported that on September 22, 2022, a bunker fire started at the Brandon Shores Power Plant, and it has caused a coal pipe mounted with two sealed sources to become exceedingly hot. It was reported that the coal from the bunker is delivered to a stock feeder via an 8 foot vertical pipe that has two gauges mounted on it. The two gauges on the coal pipe were affected by the operations to contain the fire. The RSO further reported on the conditions of the gauges that 'there does not appear to be visible signs of physical damage. Based on survey readings there does not appear to be indication of radiological issues.' The licensee has contacted Thermo Fisher to assess the damage and perform a leak test of the devices. The two fixed gauges are manufactured by Texas Nuclear Corporation, both model 5200 with device serial numbers B1421 and B1426. They contain Cesium-137 sealed sources with estimated nominal activities of 50 millicuries each with assay dates of September 1988. Results of the leak test and a detailed safety report is expected. The case has been reported to the Nuclear Material Events Database (NMED) on 10/05/2022. MDE/RHP will finalize a reactive investigation.
