As part of the ongoing GNF-A review of the … As part of the ongoing GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), facility walk downs of the UO2 sinter furnace area were performed that identified a configuration that had not been properly analyzed. Based on a review of this as-found condition, it was determined at approximately 12 p.m. on August 16, 2011 that a floor trench in the furnace area was improperly analyzed in a criticality safety evaluation. This resulted in a condition in which criticality controls that were documented as being necessary to meet double contingency were not maintained or available because the geometry of the trench was not properly modeled. There was not an actual loss of double contingency.</br>The floor trench does not normally contain uranium, and has removable covers in place to prevent material accumulation and per procedure, is routinely inspected. It was inspected during the spring maintenance shut down and was inspected again today. These inspections confirmed that no visible uranium accumulation was present. At no time was an unsafe condition present. Additional corrective actions and extent of condition are being evaluated.</br>This event is being conservatively reported pursuant to GNF-A internal procedure reporting requirements within 24 hours of discovery.</br>The licensee will notify North Carolina State Radiation Protection agency and the New Hanover County Emergency Coordinator.
