| Title | Items Relied on for Safety Associated with the Dry Scrap Recycle Furnace Improperly Analyzed |
| Event Description | During a [Global Nuclear Fuels] GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), it was determined at 1:30 PM yesterday (12/3/12) that Items Relied on for Safety (IROFS) associated with the Dry Scrap Recycle furnace operation were improperly analyzed in the ISA. Although criticality controls associated with preventing moderation intrusion exist and these controls remained in place, they were not sufficiently independent to meet performance requirements.
At no time was an unsafe condition present. The affected equipment has been shut down. An investigation is continuing which will provide additional corrective actions and extent of condition. While this did not result in an unsafe condition, this event is being reported pursuant with the reporting requirements of 10CFR70 Appendix A (b)(1) within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery. The licensee will notify state and local governmental agencies and has notified the onsite NRC Inspectors.
An extent of condition review determined there are three more areas with IROFS that are not sufficiently independent. These areas are vaporization/conversion of the Dry Conversion Process, an area used to pack material for recovery and a hood that is used to transition to a moderation restricted area in the gadolinia shop. The affected equipment in these areas has also been shut down and the investigation continues to identify additional corrective actions. The licensee notified the onsite NRC Inspectors. Notified R2DO (Blamey) and NMSS (Rahimi). |
