Computer modeling of the central storage of used fuel

This paper describes the operation and use of a computer code to model the entire used fuel management program of Ontario Hydro, including the storage, transportation, immobilization and disposal phases. The computer code called SCUFF (an acronym for System Costing of Used Fuel Facilities) has recently been extended to model central storage scenarios in addition to the reference on site storage options. SCUFF can provide yearly schedules of equipment, used fuel inventories, detailed costing schedules and overall cost summaries. The code can also be used to optimize any of the variables in the overall used fuel management program and with suitable modification could model the used fuel program of any other utility
