| Title | Uf6 Scrubber Exhaust System Not Operating as Required |
| Event Description | EVENT DESCRIPTION: It was determined at approximately 6 AM today (Eastern) that an Item Relied on for Safety (IROFS) associated with a Fuel Manufacturing Operation (FMO) exhaust system was not operating as required. An FMO scrubber exhaust system blower was determined to be not operating and resulted in a failure to meet performance requirements.
The safety function of the scrubber exhaust system is to limit the release of uranium hexafluoride (UF6) and its byproducts to the environment in the unlikely event of an accidental airborne release in a process area. Other upstream controls remained available and reliable and prevented significant quantities of UF6 and its byproducts from being released into the scrubber exhaust system. There was no release of material and at no time was an unsafe condition present. The Dry Conversion Process has been shutdown. An investigation is continuing which will provide additional corrective actions and extent of condition. While this did not result in an unsafe condition, the event is being reported pursuant with the reporting requirements of 10CFR70 Appendix A (b)(2) within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery. SAFETY SIGNIFICANCE OF EVENT: At no time was an unsafe condition present SAFETY EQUIPMENT STATUS: The Dry Conversion Process (DCP) was shutdown. STATUS OF CORRECTIVE ACTIONS: Additional corrective actions, extent of condition, and extent of cause are being investigated. There was no offsite release of UF6 as a result of the IROF failure. The licensee will inform the State of North Carolina, New Hanover County and the NRC Resident Inspector. |
