WebbUnder the Exascale Computing Project, the full-core simulation of a small modular reactor (SMR) has been pursued coupling Computational Fluid Dynamics (CFD) and neutronics. A key aspect of the modeling of SMR fuel assemblies is the presence of spacer grids and the mixing promoted by mixing vanes or the equivalent. WebbThe NEST SMR project aims to advance the understanding around the technology, regulatory framework, societal issues, spent fuel management, and economics …

The NEA Small Modular Reactor (SMR) Strategy

WebbPrevious works have added single-core and multi-core RISC-V sup-port to gem5 but only for system call emulation. The full-system simulation of gem5, on the other hand, provides accurate analysis of systems as an actual system software is loaded and run on the hard-ware platform modelled in gem5. However, full-system simulation WebbNek5000 solves the unsteady incompressible two-dimensional, axisymmetric, or three-dimensional Stokes or Navier-Stokes equations with forced or natural convection heat transfer in both stationary (fixed) or time-dependent geometry. It also solves the compressible Navier-Stokes in the Low Mach regime, and the magnetohydrodynamic … hortonia
