Model Description
This model provides a high-fidelity Large Eddy Simulation (LES) of the primary loop for the LOTUS Molten Chloride Reactor (LMCR). It utilizes the nekRS spectral element code to resolve complex flow distributions and turbulence characteristics within the loop.
- Code Used: [nekRS](https://github.com/Nek5000/nekRS) (GPU-accelerated spectral element CFD).
- Physics: Steady-state operation at the design flow rate, utilizing a custom-developed momentum source to drive the salt circulation.
- Computational Requirements: This is a high-fidelity model requiring HPC resources. It was successfully executed using 16 GPU nodes on the Hoodoo workstation at INL.
Project Description
This work is a collaborative effort with the Idaho National Laboratory (INL) team, developed under the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program.
Impact
This model serves as a benchmark for high-fidelity salt-cooled reactor simulations. By capturing detailed turbulent structures and flow patterns, it provides the necessary insights to inform and validate lower-fidelity, computationally efficient reactor design tools. This demonstration showcases the role of GPU-accelerated CFD in the development cycle of advanced nuclear reactor systems.
