Simulations of the neutron flux fluctuations, known as neutron noise, can be performed by
means of the spherical harmonics equations (SP N) approximation with higher accuracy …

The mechanical vibrations of fuel assemblies have shown to give high levels of neutron
noise, triggering in some circumstances the necessity to operate nuclear reactors at a …

Abstract Machine learning-based modeling of reactor physics problems has attracted
increasing interest in recent years. Despite some progress in one-dimensional problems …

This study focuses on solving the multigroup diffusion eigenvalue problem using the finite
element method. In particular, the study assesses the potential reduction of numerical costs …

In this paper, we propose a multi-scale finite element method for solving the two-group
neutron diffusion equation, which represents the distribution of neutrons in thermal reactors …

Insufficiently explained magnitudes and patterns of flux fluctuation observed mainly in KWU
PWRs are recently investigated by various European institutions. Among the numerical tools …

The theoretical calculation of neutron noise plays an important role in interpreting
experiments and providing abnormal directivity information in the reactor. Therefore, it is …

Power reactor neutron noise is the fluctuations or perturbations of neutron flux induced by
small oscillations of various macro parameters (density, temperatures, mechanical …
