COSI7: THE NEW CEA REFERENCE ELECTRO-NUCLEAR SIMULATION TOOL
CEA, DES, IRESNE, DER, SPRC, F-13108 Saint-Paul-lez-Durance, France.
Published online: 22 February 2021
Nuclear fuel cycle scenario studies are used as a prospective analysis tool in order to provide stakeholders with decision aid. Nuclear fuel cycle simulation tools model the deployment of reactor fleets, the mass flows in the fuel cycle, and track the nuclear materials. The CEA has been developing for more than 30 years the nuclear fuel cycle tool COSI. The latest version, COSI7, was designed in order to model dynamic systems of ever-increasing complexity with improved user experience. The new developments include functionalities designed to improve the user experience as well as new physical models and post-processing capabilities. COSI7 supersedes COSI6 as the CEA reference nuclear fuel cycle simulation code starting January 2020.
Key words: COSI / fuel cycle simulation tool / scenario
