Existence and Uniqueness Theorems for the Neutron Transport Equation [PDF]

Journal of Mathematical Physics, 1963
In an attempt to understand the conditions under which the neutron transport equation has solutions, and the properties of those solutions, a number of existence and uniqueness theorems are proved. One finds that the properties of the solution are closely related to the boundedness of the source as well as to certain velocity-space integrals of the ...

Neutron angular flux reconstruction in slab geometry using multigroup discrete ordinates transport models

Brazilian Journal of Radiation Sciences, 2023
In this article, we present an application of the coarse-mesh Deterministic Spectral Method (SDM) to generate multigroup angular fluxes in one-dimensional spatial domains using the neutron transport stationary equation, in the formulation of discrete ...

A new approach for calculation of the neutron noise of power reactor based on Telegrapher's theory: Theoretical and comparison study between Telegrapher's and diffusion noise

Nuclear Engineering and Technology, 2020
The telegrapher's theory was used to develop a new formulation for the neutron noise equation. Telegrapher's equation is supposed to demonstrate a more realistic approximation for neutron transport phenomena, especially in comparison to the diffusion ...

Direct discrete method and its application to neutron transport problems [PDF]

Nuclear Technology and Radiation Protection, 2003
The objective of this paper is to introduce a new direct method for neutronic calculations. This method, called direct discrete method, is simpler than the application of the neutron transport equation and more compatible with the physical meanings of ...

Analysis of Kobayashi benchmark with indigenous Monte Carlo neutron transport code PATMOC

Physics Open, 2023
The solution of the neutron transport equation is the basic input for the reactor physics design of a nuclear reactor system. Because of the complexities of geometry and cross-section data, the neutron transport equation is generally solved using ...

Solution of neutron-transport multigroup equations system in subcritical systems [PDF]

Nuclear Energy and Technology, 2018
An iteration method has been implemented to solve a neutron transport equation in a multigroup diffusion approximation. A thermoelectric generator containing plutonium dioxide, used as a source of thermal and electric power in spacecraft, was studied.

Proton Differential Elliptic Flow and the Isospin-Dependence of the Nuclear Equation of State [PDF]

, 2001
Within an isospin-dependent transport model for nuclear reactions involving neutron-rich nuclei, we study the first-order direct transverse flow of protons and their second-order differential elliptic flow as a function of transverse momentum.

STUDY OF THE EIGENVALUE SPECTRA OF THE NEUTRON TRANSPORT PROBLEM IN PN APPROXIMATION [PDF]

EPJ Web of Conferences, 2021
The study of the steady-state solutions of neutron transport equation requires the introduction of appropriate eigenvalues: this can be done in various different ways by changing each of the operators in the transport equation; such modifications can be ...
