Summary of analysis for EPIP-EOF-6, Offsite Dose Assessment using the Unified RASCAL Interface EPIP-EOF-6 revised FC-EPF-52 deleted FC-EPF-53 deleted EP-FC-110-200-AD-F-01 issued EP-FC-110-200-AD-F-02 issued FC-EPF-52, Manual Dose Assessment for RM-043, and FC-EPF-53, Release Rate Calculation Spent Fuel Pool and Steam Generator for Beyond Design Basis Flood was made when EAGLE was the dose assessment software. FC-EPF-52 calculations that were put in place for EAGLE are not as precise as using URI because it takes into account more assumptions. FC-EPF-52 is being revised and re-titled to EP-FC-110-200-AD-F-01 that works with the approved URI software. This change will use the approved computer model (URI), which has less assumptions and is more accurate, for dose assessment if RM-043 is Out of Service and therefore will not reduce the effectiveness of dose assessment or the plan. FC-EPF-53 currently has the user perform calculations that are plugged into EAGLE and FCS is not using EAGLE anymore so FC-EPF-53 is being revised and re-titled to EP-FC-110-200-AD-F-02 that works with the approved URI software. Both of these forms are being re-titled in order to match the Exelon numbering system. EPIP-EOF-6 is being revised to add a step to go to these forms in the applicable situations.
