Nuclear reactor modeling poses two major challenges: The complexity of technically sophisticated assemblies that must meet rigorous safety demands, and the need for large-scale collaboration among designers, engineers and shareholders, many of which do not have specific modeling skills.
In testing with Oak Ridge National Laboratory, the solution delivered the following benefits:
Organizations such as Oak Ridge National Laboratory (ORNL) are migrating to small modular nuclear reactors (SMRs) about one-third the size of the current generation of nuclear power plants. SMRs promise faster development cycles, lower costs, greater scalability and increased site flexibility. But SMRs still require an extremely high level of complexity and large-scale collaboration.
Modelon has developed an FMI-based solution called MoDSIM that helps meet the collaboration demands of organizations developing SMRs. It provides a web-based interface that uses an external platform for easy model configuration and local application deployment for simulation using FMI Add-in for Excel.
MoDSIM has been tested by Modelon and engineers from Oak Ridge National Laboratory on a liquid-metal small modular reactor concept modeled using Dymola and exported via FMI.
”Modelon helps us develop a low threshold of entry for non-modelers to simulate reactor design concepts. The combination of a dynamic modeling interface, supported libraries, the modeling language and the FMI Add-in for Excel enables novice modelers to run parametric cases across a wide suite of...Richard Hale , principal investigator for advanced small modular nuclear reactor program at Oak Ridge National Laboratory
