Multi-physics modelling and simulation of nuclear reactors using OpenFOAM

Speaker: Carlo FIORINA (Texas A&M University, USA), Stephan KELM (Forschungszentrum Jülich GmbH (FZJ), Germany), Stefano LORENZI (POLIMI, Italy)
Joint ICTP-IAEA Workshop on Open-Source Nuclear Codes for Reactor Analysis | (smr 3865)
This workshop offers a comprehensive journey in cutting-edge computational techniques for nuclear reactor analysis, providing an in-depth understanding of reactor neutronics, thermal hydraulics and system analysis at different scales. Participants will be led through the essential stages required to conduct engineering-level multi-physics simulations.
The open-source movement is expanding and extending substantial assistance to all nations by using such advantages as lower starting cost, more flexibility in software development, robust community-driven support, and easier license management, without being contractually locked to a single vendor. To aid the progress and implementation of open-source multi-physics simulation tools for the examination of advanced nuclear power reactors, the IAEA has launched the Open-Source Nuclear Codes for Reactor Analysis (ONCORE) initiative, which includes various scheduled events. This workshop will prove beneficial to both developed and developing countries, as it will benefit institutions and individual users alike, by providing research, education, and training opportunities.
Active discussions, group activities, poster sessions and various mixed learning approaches will be used to share knowledge and new ideas between recognized experts in the field of open-source tools for nuclear reactors and workshop participants.
Topics:
General overview, theoretical background and practical exercises will be offered for
• OpenFOAM and its derivatives for CFD simulation of multi-physics and multi-scale problems
• GenFOAM for core thermal hydraulics, neutron transport and structural mechanics modelling
• Offbeat for fuel performance simulation
• Containment FOAM for severe accidents simulation
• OpenMC Monte-Carlo neutron transport
• MOOSE parallel finite element framework for multi-physics, multi-scale simulations
• ARMI Advanced Reactor Modelling Interface
