In this paper the simplified double-spherical harmonics, SDPN, approximation of the neutron
transport equation is proposed. The SDPN equations are derived from the multi-group DPN …

Introduction Shielding of ionizing radiations, which are gamma rays, neutrons, and X-rays,
can be achieved by attenuating its intensity using different materials. Protection is therefore …

Abstract The well-known Discrete Ordinates (SN) approximation is little effective in
multidimensional radiation shielding calculations. In the presence of geometrically large and …

Discrete ordinate (SN) and filtered spherical harmonics (FP N) based schemes have been
proven to be robust and accurate in solving the Boltzmann transport equation but they have …

For the safety assessment of (v) SMR and MMR, having small and heterogeneous
configurations, the GRS finite element based neutronic code FENNECS was equipped with …

Over the years, a growing interest in the application of deterministic solvers to the
calculationof radiation shielding problems has been observed. Deterministic solvers can …

The application of continuous and discontinuous approaches of the finite element method
(FEM) to the neutron transport equation (NTE) has been investigated. A comparative …

In this work a parametric representation of the angular neutron flux in the energy range from
1 eV to 10 MeV is determined from a Monte Carlo simulation with initially 10 6 neutrons. The …
