| Title | Equipment Configuration Different than Analyzed in the Isa |
| Event Description | During a review of Integrated Safety Analysis (ISA) and criticality evaluation assumptions for a floor cleaning scrubber used in the Dry Conversion Process facility, it was determined that an equipment configuration was different than that analyzed in the ISA. Field verification of the floor cleaning scrubber recovery tank determined that its capacity was greater than the safe volume limit referenced in the analysis. The tank volume is credited as an IROFS [Items Relied On For Safety] in the ISA summary. Based on a review of this as-found condition, discovered at approximately 1120 EDT on September 29, 2011, it was determined that the system was different than analyzed in the ISA and resulted in a failure to meet performance requirements.
The tanks for the floor cleaning scrubbers were inspected and no unsafe condition existed. 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. 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 will notify the NRC Region 2, North Carolina Radiation Protection Agency and New Hanover County Emergency Management. |
