| Title | Incomplete Documentation of Criticality Safety Controls in Integrated Safety Analysis Summary |
| Event Description | During a GNF-A ongoing review of the Fuel Manufacturing Operation (FMO) Integrated Safety Analysis (ISA), it was discovered at 3pm yesterday (11/11/09) that there may be an incomplete list of criticality safety controls associated with the Pellet and Rod Load Fabrication areas in the ISA Summary.
At 7pm, it was determined that the list of Items Relied On For Safety (IROFS) was incomplete and the affected equipment was shut down pending revision of the ISA to document IROFS for these processes. Notwithstanding the documentation deficiency, the controls associated with moderator intrusion and geometry remained in place, functional, and maintained with appropriate management controls. While this discovery did not result in an unsafe condition, it is being reported on 11/12/09 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 />. Safety Significance of Events: Low safety significance - All process criticality safety controls remained intact and functioning for this processes. Safety Equipment Status: Pellet and Fuel Load fabrication areas are shutdown and will remain shutdown until the ISA review is completed. Status of Corrective Actions: Pellet and Rod Load Fabrication areas will remain shutdown pending final investigation results and identification of additional IROFS. The licensee notified NRC Region 2 Inspector (Crespo) and will notify state and local authorities. |
