| Title | 24 Hour Notification Bulletin 91-01 Criticality Control |
| Event Description | Reason for Notification: Thirteen polypaks of uranium powder were dumped into a bulk container without a documented visual inspection of the bulk container. A visual inspection is performed prior to introducing SNM into a bulk container.
Upon recognizing that the documentation was missing, the operator confirmed that a visual inspection had been performed prior to introducing SNM, but had not been documented. The operator then re-inspected the bulk container and found no trace of moderator. The powder dumped into the container was previously documented to contain leas than 0.3 weight percent moisture. Double Contingency Protection: Double contingency protection for the ADU Bulk Blending System is assured by preventing moderator from entering a bulk container. Empty bulk containers are inspected for the presence of moderator prior to introducing SNM. Failure to document the inspection left less than previously documented double contingency protection for the system. In accordance with Westinghouse Operating License (SNM-1107), paragraph 3.7.3 (c.5b), this event satisfies the criteria for a 24-hour notification. Summary of Activity: Bulk blending operations were discontinued. Training was performed for each shift prior to resuming operations. Conclusions: Less than previously documented double contingency protection remained. At no time was the health or safety to any employee or member of the public in jeopardy. No exposure to hazardous material was involved. The Incident Review Committee (IRC) determined that this is a significant incident in accordance with governing procedures. A causal analysis will be performed. |
