The fluoride-salt-cooled high-temperature reactor (FHR) is a Generation IV nuclear energy
system with huge potential for further development. Owing to its unique advantages, such as …

This paper reviews the recent three-year progress on the investigations of pebble bed flows
in nuclear engineering. Both the application of pebble beds in the fission reactors and the …

Cardinal is an open-source application that couples OpenMC Monte Carlo transport and
NekRS computational fluid dynamics to the Multiphysics Object-Oriented Simulation …

Advanced reactor concepts span the spectrum from heat pipe–cooled microreactors,
through thermal and fast molten-salt reactors, to gas-and salt-cooled pebble bed reactors …

With the next generation of nuclear reactors under development, modeling and simulation
tools are being developed by the US Department of Energy to support their design …

Pebble-bed reactors (PBRs) rely on a continual feed of fuel pebbles being cycled through
the core. As a result, they require a “run-in” period in order to reach an equilibrium state. The …

A new approach is proposed to evaluate the safety of molten-salt reactors (MSRs), using
advanced modeling and simulation (M&S) tools. This approach augments the Monitoring …

The development of fluoride-cooled high-temperature reactors has greatly heightened the
need for a thorough comprehension of heat transfer in packed beds that are cooled by liquid …

Pebble bed very high-temperature gas-cooled reactor (VHTR) has many economic and
safety advantages, such as high safety and high outlet temperature. It uses fuel pebbles with …

Modeling the run-in of a pebble-bed reactor (PBR) can be challenging as a result of
changes in the power, fuel type, and temperatures that occur throughout the run-in period …
