Title	Unanalyzed Condition
Event Description	The following information was provided by the licensee via phone and email: The facility is in a safe and stable configuration and no accident has occurred. Urenco USA stores '1S' bottles in storage cabinets that are verified as safe-by-design, and have been analyzed for storage in the storage area as sub-critical under all normal and credible abnormal conditions. '1S' bottles were removed from cabinets and placed onto carts awaiting transfer to new approved cabinets in the cylinder receipt and dispatch building (CRDB). An analysis exists for this configuration of '1S' bottles on carts in other areas of the plant but does not presently exist for '1S' bottles stored on carts in the CRDB. The collection of '1S' sample bottles on several mobile carts potentially falls outside of the normal operating conditions analyzed in nuclear criticality safety and integrated safety analysis (ISA) related documentation and results in the facility being in a state that was different than analyzed in the ISA. Corrective actions have begun. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: Personnel access to the area has been restricted pending completion of the evaluation. The licensee has notified NRC Region 2.
