["This tool is to enable preliminary cost of fuel estimates for new fuel concepts using spent nuclear fuel (SNF) as the nuclear materials source."]
[]
["Reminder: Use of this tool and submission in the application package is OPTIONAL."]
["When choosing to use this tool, applicants should be aware of the following key assumptions, both which may lead to underestimation of fuel costs:"]
["1) There are no costs associated with acquiring SNF feedstock."]
["2) 100% of the limiting nuclear material in the SNF feedstock can be recovered. This minimizes the quantity of SNF mass needed to meet nuclear material input requirements and the mass to be reprocessed, which minimizes the cost of reprocessing (also assuming that reprocessing cost is only a function of the mass to be reprocessed). The limiting nuclear material is the lowest ratio of feedstock fraction to fuel mass fraction. For example, Pu (feedstock fraction = 0.01 and fuel mass fraction = 0.20) is the limiting material in the TRU Fuel References used here."]

["In order to use this tool, applicants will need to be able to estimate the following for their proposed fuel:"]
["Fuel composition"]
["Fuel mass fraction - U (kg U/kg fuel, the fraction of U in the fuel by mass)"]
["Fuel mass fraction - Pu (kg Pu/kg fuel, the fraction of Pu in the fuel by mass)"]
["Fuel mass fraction - Other nuclear materials (kg other nuclear material/kg fuel, the fraction of other nuclear material in the fuel by mass)"]
["Feedstock composition, where feedstock = spent fuel or other nuclear waste material that will be reprocessed for use in fuel fabrication"]
["Feedstock fraction - U (kg U/kg SNF feedstock, the fraction of U in the feedstock by mass)"]
["Feedstock fraction - Pu (kg Pu/kg SNF feedstock, the fraction of Pu in the feedstock by mass)"]

["Edit cells that are highlighted in yellow."]
["Provide a name for the proposed fuel."]
["To access reference cost data specific to Metal or Ceramic Fuels using TRU feestocks, select the fuel type of interest from the pull down menu. Note: These data sets are just for reference and should not discourage applicants from proposing fuels outside these types."]
["Fill in all values in the User Inputs table (Table 1) under the proposed fuel name."]
["Use the Notes section to explain inputs, and cite sources for the values used if applicable. Add sheets to support additional calculations as needed and reference these in the Notes."]
["If applicants plan to include nuclear materials in the proposed fuel other than U or Pu, they must provide additional details on this plan in the Notes."]
[]
["Reference data is in blue and can be used as a placeholder for any missing data."]
["If applicants choose to use reference data in the results submitted to ARPA-E, they must provide an explanation for this choice (e.g., \"We do not yet have data on this or sufficient process information to estimate\")."]
