GENERATING ALBEDO BOUNDARY CONDITIONS FOR NODAL DIFFUSION CODES USING SERPENT 2 [PDF]
EPJ Web of Conferences, 2021 We use the Serpent Monte Carlo code to produce total and partial albedo boundary conditions that can be used to model the Loviisa NPP VVER-440 core with the nodal neutronics tools of Fortum. The albedo generation process is described in detail.

Inverse Nodal Problem for a Conformable Fractional Diffusion Operator [PDF]
Inverse Problems in Science and Engineering, 2020 In this paper, a diffusion operator including conformable fractional derivatives of order {\alpha} ({\alpha} in (0,1)) is considered. The asymptotics of the eigenvalues, eigenfunctions and nodal points of the operator are obtained.

New 3D Diffusion Code Based on The Nodal Polynomial Expansion
Brazilian Journal of Radiation Sciences, 2021 Nodal Expansion Method (NEM) is widely employed in the neutronic design of nuclear reactors core. The main reason is its higher computational performance and efficiency when compared with the conventional fine mesh difference method or finite element ...
