The inspectors identified an Unresolved It … The inspectors identified an Unresolved Item (URI) associated with the licensees ability, during an accident, to accurately quantify radioactive releases, potentially having an adverse impact on the licensees ability to effectively implement its Emergency Plan. Description: During a walkdown of the facility and discussions with licensee staff, the inspectors identified that the SGT system accident range monitor (AXM) noble gas detector did not utilize the fluctuating background subtraction feature of the unit and only subtracted a fixed background rate. The inspectors questioned this set-up because the physical location of the monitor was in close proximity to the SGT system filtration system, which could significantly change dose rates in the area during an accident. The function of the AXM is to assess radioactivity being released from the plant during accident conditions. These readings are used for various purposes, including accident classification and off-site dose assessment, both of which can affect the protective action recommendations made by the licensee. On September 29, 2016, the licensee provided the inspectors an assessment of the potential impact of fluctuating background from the filtration system on the AXM noble gas detector. This URI remains under review by the inspectors to determine if there is an impact to the AXM noble gas detector that could affect the licensees ability to implement its Emergency Plan and whether any violation of regulatory requirements occurred.
