This spreadsheet accompanies the paper: De Roo, Guillaume and John Parsons, 2011, "A Methodology for Cal An earlier version of the paper appeared as This is also the methodology used in Chapter 7, Economics, of th Color Guide Front End Reactor & Misc. Back End Variable Input General Description the Levelized Cost of Electricity", Center for Energy and Enviro The following sheets aim at the calculation of the levelized cost of electricity (LCOE) and its components for different fuel cycles of interest. The usual way to calculate the LCOE is to use the reactor as a unit of analysis. Here, because cycles can be complex and do not necessarily reach a steady-state, the unit of analysis is the fuel. Namely, we follow an initial mass of UOX through the system. The practical consequence is that costs are regarded as services to this fuel, e.g. the use of The calculations begin with the 'Inputs Summary' worksheet. Then there are a set of intermediate worksheets, including the 'Fuel Module', the 'LWR Module', the 'FR Module', the 'Disposal Module' and the 'R&R Module'. Then there are a set of final worksheets calculating the LCOE for each of the three cycles: 'Fuel Cycle 1', 2 and 3. Finally, the results are collected into a Results Summary worksheet. The inputs and results are - 'Inputs Summary' contains all inputs used in the document. These are highlighted in gray. Related parameter values calculated from these inputs are shown here as well. - 'Fuel Module' uses the fuel composition data in 'Inputs Summary' depending on the selected scenario. It then proceeds to intermediate mass flow and economic calculations. In addition, there are 2 intermediate fuel cycle products, Reprocessed Uranium and U/TRU blend; their value is endogeneous - 'LWR Module' uses the technical and cost data for thermal reactors in 'Inputs Summary' to build the levelized cost related to the reactor usage. - 'FR Module' does a similar calculation for fast reactors Disposal Module' calculates the cost of disposal from the historical and expected Yucca Mountain costs. It is used as an alternative input on the 'Input Summary' page.
