| Title | Unanalyzed Condition - Nuclear Material Received in Excess of License Limits |
| Event Description | The following is a synopsis of information provided by the licensee via email:
Uranium Recovery and Recycle Services (URRS) personnel were offloading ash on 11/1/22 that they had received in 2003 from the decommissioned Hematite site at Dock 3. The operators opened the Type A drum and from an inner canister pulled out the bag of Hematite ash. The bag had a tag indicating enrichment levels in excess of their license limits. Upon discovery, the operators contacted criticality safety engineering and the safeguards coordinator. The operators were instructed to replace the bag in the canister and drum and to segregate the drums that contained material potentially greater than license limits in accordance with generally accepted guidance for criticality safety. An extent of condition was performed using materials control and accounting records of the received material. It was discovered that several drums potentially contain material in excess of license enrichment limits. The plant is in a safe condition and the steps taken in response to this event are considered to be conservative. This report is being made per 10 CFR 70 Appendix A (b)(1). This event resulted in the facility being in a state that was not analyzed in their Integrated Safety Analysis Report and resulted in a failure to meet the performance requirements of 10 CFR 70.61, specifically there were no controls in place due to it being an unanalyzed condition. Westinghouse is unable to open, sample, and test the ash to determine enrichment until the proposed process has been analyzed with documented controls in place. This issue has been entered into the licensee's corrective action program as IR-2022-9728.
The following is a synopsis of information provided by the licensee via email: On 9/12/2023, while offloading additional barrels of Hematite Ash from the the 2003 shipment, A URRS operator identified that the tag for a drum showed the contents have a higher enrichment than that which is recorded in the Chemical Area Manufacturing and Process System (ChAMPS) and on the original paperwork provided by Hematite Fuel Operations. The unloading activity was stopped, and URRS Management and Nuclear Criticality Safety were notified. The unopened pail was placed back in the drum and the drum was segregated from other items in the area. Environmental Health and Safety requested that the remaining seven drums be opened and the contents tag for each be checked against the information in ChAMPS and the original paperwork from Hematite Fuel Operations. This was done. This report is conservatively being made as an update to Event Notification 56199 under reporting criterion 10 CFR 70 Appendix A (b)(1) as an event that resulted in the facility being in a state that was not analyzed in the Integrated Safety Analysis, and resulted in a failure to meet the performance requirements of 10 CFR70.61 similar to the 9 drums of Hematite Ash that were discovered in November 2022 due to it being an unanalyzed condition. Westinghouse believes it is likely that the enrichment listed on the tag of the drum is inaccurate. The issue has been entered into the corrective action program as IR-2023-8953.
