Abstract
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.
Highlights
Nuclear fuel cycle scenario studies are used as a prospective analysis tool in order to provide stakeholders with decision aid
COSI7 is a complete re-write in C++ of COSI6, designed in order to tackle the new challenges induced by the ever-increasing complexity of the scenarios
This section details some of the new physical models that were introduced into COSI7 in order to provide more options to fine-tune scenarios and refine the physical description of facilities and processes
Summary
Nuclear fuel cycle scenario studies are used as a prospective analysis tool in order to provide stakeholders with decision aid. They aim to help decision-makers understand the impact of decisions in complex systems. As COSI6 performance improved, scenarios simulations featured an increased level of operational detail and required always more fine-tuning of facilities and strategies, progressively shifting the time-consuming processes of making scenarios from simulation towards dataset generation and scenario results analysis. The new features of COSI7 can be broadly separated into two categories: improving the user experience and refining the physical models.
