| Title | Unanalyzed Condition - System As-Found Condition Not Fully Described in Isa |
| Event Description | As part of the ongoing GNF-A review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), an accident sequence associated with hydrogen piping in the laboratory area was being evaluated. As part of this evaluation, a configuration that had not been properly analyzed was identified. Based on a review of this as-found condition, it was determined at approximately 11 AM [EST] on November 9, 2012 that the system was not fully described in the ISA and resulted in a failure to demonstrate performance requirements were met.
Hydrogen supply to the affected piping system has been isolated. Additional corrective actions and extent of condition are being evaluated. This event is being reported pursuant to 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 determined the as-found condition is of minimal safety significance. The licensee will be notifying NRC Region 2, State, and local authorities. |
