We developed a C++ computational tool for physics-based shape and topology optimization
and integrated it into the MOOSE multiphysics simulation framework. The tool implements …

This paper presents an experimental investigation of the wall corrugation effect on three
threshold velocities for air–water flow. Those threshold velocities refer to different …

CEA is currently working on a new ZPR called ZEPHYR (Zero power Experimental PHYsics
Reactor), to be built on the Cadarache Center in the next decade. Its awaited experimental …

Best-estimate codes, which couple neutronic and thermal-hydraulic solvers, are mainly used
for safety analyses of nuclear power plants. During the past decade, the application of these …

Studies related to severe core accidents constitute a crucial element in the safety design of
Gen‐IV systems. A new experimental program, related to severe core accidents studies, is …

Fluoride-salt-cooled High-temperature Reactors (FHRs) are a variant of nuclear reactor
offering high power densities and operating temperatures. This paper proposes a new …

In this study, a high‐fidelity Monte Carlo model was utilized to investigate the localized
behavior of the power peaking factor in a reactor core. The model considered the effect of …

A multiparameter representativity approach for the design of Advanced full MOX BWR core
physics experimental programs in ZPR was developed. The approach is based on sensitivity …
