UNANALYZED CONDITION

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.

AGREEMENT STATE REPORT - STUCK SOURCE

The following information was provided by the Rhode Island Department of Radiological Health via email:

"At 0006 EDT, on July 14th, 2025, an Electric Boat employee was attempting to retract an Ir-192 source of 19.5 Ci. The employee was only able to retract the source halfway back to the exposure device when the source would not move any further. The employee then cranked the source back out into the collimator to provide shielding. The employee then contacted their supervisor to report the emergency notification and follow the emergency procedures as required. The boundaries were verified to be less than 0.5 mR/hr at all boundaries. There were no un-monitored personnel in the area. Additional personnel were provided to maintain control of the area. The radiation safety officer (RSO) was contacted at 0013 and notified of the hung source. The RSO arrived on site at approximately 0043 to assess the incident and determine a corrective action on how to move forward. The RSO and the radiographer returned the radioactive source to the exposure device at approximately 0300. The highest dose received by any individual of the recovery team was 1 mrem. The source in the exposure device was secured and returned to storage."
