Monte Carlo Methods for the Neutron Transport Equation [PDF]
SIAM/ASA Journal on Uncertainty Quantification, 2022 This paper continues our treatment of the Neutron Transport Equation (NTE) building on the work in [arXiv:1809.00827v2], [arXiv:1810.01779v4] and [arXiv:1901.00220v3], which describes the flux of neutrons through inhomogeneous fissile medium. Our aim is to analyse existing and novel Monte Carlo (MC) algorithms, aimed at simulating the lead eigenvalue ...

Ultra-thin 3D silicon sensors for neutron detection
, 2012 We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 µm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the ...

Neutron imaging of lithium concentration in LiNi0.33Mn0.33Co0.33O2 cathode
, 2020 LiNi0.33Mn0.33Co0.33O2 (NMC) is a promising substitute for LiCoO2 because of its good thermal stability and high energy density. In this work, the lithium concentration distributions in an NMC cathode using neutron computed radiography technique at Oak ...

Results of the reactor dosimetry experiments performed for verification of the neutron transport calculations at the Hungarian Paks Nuclear Power Plant [PDF]
EPJ Web of ConferencesThe operational lifespan of all four units at the Hungarian Paks Nuclear Power Plant (NPP) has been extended by 20 years beyond the original 30-year term. This extension has been implemented gradually, in one- to two-year increments, since 2013.

Laplace-transform-based method to calculate back-reflected radiance from an isotropically scattering half-space [PDF]
, 1997 We present a method to determine the back-reflected radiance from an isotropically scattering half-space with matched boundary. This method has the advantage that it leads very quickly to the relevant equations, the numerical solution of which is also ...
