Fuel cycle simulators are used worldwide to provide scientific assessment fuel future strategies. Those tools help understanding the physics and determining most impacting drivers at scale. A standard scenario calculation is usually based on a set of operational assumptions, such as reactor Burn-Up, deployment history, cooling time, etc. Scenario output then evolution isotopes mass in facilities that composes nuclear fleet. The increase computing capacities use neutron data fast predictors...
Nuclear scenario studies are performed to explore the impact of possible evolutions nuclear fleets. The fuel cycle simulation tool COSI, developed by CEA, is used model these dynamic scenarios and evaluate them with respect uranium plutonium management, reprocessing waste production. In recent years, have focused on transitions from current French fleet a deployment SFR. However, Multi-annual Energy Planning has recently postponed this technology second half 21st century. Alternative...
This paper presents new metamodels based on artificial neural networks trained full core 3D depletion simulations performed with APOLLO2 and CRONOS2. They are used to estimate the irradiation cycle length, discharge burn-up of each fuel assembly type radial power factor a PWR loaded 30% MOX fuels, as function initial plutonium composition. allow explore impact isotopic vector reactor characteristics can be for scenarios studied future cycle. Some exclusion domains in phase space identified...
Scenario simulations are the main tool for studying impact of a nuclear reactor fleet on related fuel cycle facilities. This equilibrium preliminary study aims to present functionalities new and show wide variety reactors/cycles/strategies that can be studied in steady state conditions validated with more details thanks dynamic code. Different types scenario simulation tools have been developed at CEA over years, this focuses codes. Dynamic code models ingoing outgoing material flow all...
