During a review of the Integrated Safety A … During a review of the Integrated Safety Analysis (ISA) for a 3-gallon can elevator used in the Dry Scrap Recycle (DSR) area, it was determined that the ISA incorrectly describes the IROFS used to control movement of SNM. The system is composed of two sequential can elevators that are used to move SNM to different floors. A Fuel Business System (FBS) automated control and associated gate controls are designated as one of the Items Relied On For Safety (IROFS). In the ISA, this IROFS is incorrectly attributed to the 2nd can elevator instead of the 1st can elevator. Based on a review of this condition, determined at approximately 1400 on October 5, 2011, it was determined that the system was different than analyzed in the ISA and resulted in a failure to meet performance requirements.</br>The FBS and associated gate control were in place at all times on the 1st can elevator, was operating correctly, and supported by management measures. No unsafe condition existed. The ISA and associated documentation are being updated to designate the correct can elevator and associated controls.</br>Operation of the equipment has been suspended pending additional review and implementation of corrective actions. Additional corrective actions and extent of condition are being evaluated.</br>This event is being reported pursuant to the reporting requirements of 10CFR70 Appendix A (b)(1) within 24 hours of discovery.</br>The licensee will notify NRC Region 2 and State and local authorities.
