DESCRIPTION: | The model was developed as a part of the study, "Advanced Fuel Cycles and Waste Management", which was performed during 20032005 by an ad-hoc expert group under the Nuclear Development Committee in the OECD/NEA. The model was designed for an efficient conduct of nuclear fuel cycle scheme cost analyses. It is simple, transparent and offers users the capability to track down the cost analysis results. All the fuel cycle schemes considered in the model are represented in a graphic format and all values related to a fuel cycle step are shown in the graphic interface, i.e., there are no hidden values embedded in the calculations. All data on the fuel cycle schemes considered in the study including mass flows, waste generation, cost data, and other data such as activities, decay heat and neutron sources of spent fuel and highlevel waste along time are included in the model and can be displayed. The user can modify easily the values of mass flows and/or cost parameters and see the corresponding changes in the results. The model calculates: frontend fuel cycle mass flows such as requirements of enrichment and conversion services and natural uranium; mass of waste based on the waste generation parameters and the mass flow; and all costs. It performs Monte Carlo simulations with changing the values of all unit costs within their respective ranges (from lower to upper bounds). |

MEDIA QUANTITY: | 1 |
METHOD OF SOLUTION: | In Monte Carlo simulation, it is assumed that all unit costs follow a
triangular probability distribution function, i.e., the probability that the unit cost has a value increases linearly from its lower bound to the nominal value and then decreases linearly to its upper bound. |
COMPUTER: | IBM PC |
OPERATING SYSTEMS: | Windows |
SOFTWARE LIMITATIONS: | The limit for the Monte Carlo iterations is the one of an Excel worksheet, i.e. 65,536.
Calculations are done immediately as usual in Microsoft Excel applications. Sensitivity analyses take some time, up to a few minutes, for copying and pasting values. Monte Carlo simulation takes time depending on the number of iterations and the speed of the PC. For 10,000 iterations, it may take more than 30 minutes, depending on the computer. |
UNIQUE FEATURES: | This model does sensitivity analyses and Monte Carlo simulations using macros in Microsoft Excel. |
