Exascale Simulations of Fusion and Fission Systems
Misun Min, Yu-Hsiang Lan, Paul Fischer +11
We discuss pioneering heat and fluid flow simulations of fusion and fission energy systems with NekRS on exascale computing facilities, including Frontier and Aurora. The Argonne-b…
Study of Turbulence and Pressure Recovery in the Heat Pipe Vapor Flow Using the Spectral-Element Method
Carolina Bourdot Dutra, Tri Nguyen, Elia Merzari +1
Heat pipes can efficiently and passively remove heat in nuclear microreactors. Nevertheless, the flow dynamics within heat pipes present a significant challenge in designing and op…
Toward Direct Numerical Simulation of Turbulent and Transitional Flow in Hexagonal Subchannels for Helium Conditions
Carolina Bourdot Dutra, Elia Merzari
Understanding the coolant thermal hydraulics in rod bundles is essential to the design of nuclear reactors. However, flows with low Reynolds numbers present serious modeling challe…
Study on Laminar-Turbulent Transition in Square Arrayed Rod Bundles
Carolina Bourdot Dutra, Elia Merzari
The study of coolant flow behavior in rod bundles is of relevance to the design of nuclear reactors. Although laminar and turbulent flows have been researched extensively, there ar…
Validation and Comparison of HI-STORM Overpack Thermal-Hydraulic Model with MOOSE and NekRS
Sinan Okyay, Elia Merzari, David A. Reger +4
Nuclear power is a significant source of electricity in the United States, but the average U.S. nuclear power plant is around 40 years old. Safe management of spent nuclear fuel (S…
A Preliminary Fluid-Structure Coupling of NekRS and MOOSE via Cardinal
A. Chaube, A. J. Novak, H. Yuan +4
Fluid-Structure Interaction (FSI) is a significant phenomenon in most nuclear reactors, causing effects such as Flow-Induced Vibration (FIV) and thermally-driven Core-Radial Expans…
