The Influence Mechanism of Neutron Kinetics of the Accelerator-Driven Subcritical Reactor Based on the Fast/Thermal Neutron Spectra by Monte Carlo Homogenization Method

open access: yesEnergies, 2023
For the sake of understanding the mechanism of deep subcriticality and high heterogeneity of neutron fluence rate in time–space on the neutron kinetics of the Accelerator-driven Subcritical Reactor Subcritical Reactor (ADSR) under varied beam transients ...

A new surrogate method for the neutron kinetics calculation of nuclear reactor core transients

open access: yesNuclear Engineering and Technology
Reactor core transient calculation is very important for the reactor safety analysis, in which the kernel is neutron kinetics calculation by simulating the variation of neutron density or thermal power over time.

On a significant slowing-down of the kinetics of fast transient processes in a fast reactor [PDF]

open access: yesNuclear Energy and Technology, 2020
The kinetics of nuclear reactors is determined by the average neutron lifetime. When the inserted reactivity is more than the effective delayed neutron fraction, the reactor kinetics becomes very rapid.

On the concept of “effective delayed neutron fraction” [PDF]

open access: yesNuclear Energy and Technology, 2022
The article considers methodological issues related to the conceptual and terminological apparatus of the dynamics of nuclear reactors. Based on an elementary analysis of the standard point reactor kinetics equations, the author shows that it is ...

Influence of the main neutron absorbers poisons coupled to the Point Kinetics model by the Rosenbrock’s method

open access: yesBrazilian Journal of Radiation Sciences, 2022
In this work, the Neutron Point Kinetics equations are solved for six groups of delayed neutron precursors and different types of ramp reactivity, considering the temperature effects by the Rosenbrock’s method, to verify the methodology. Furthermore, the

Assessment of the neutron flux stability in a high power BN-type reactor in terms of modal spatial kinetics [PDF]

open access: yesNuclear Energy and Technology, 2021
The article discusses the neutron flux stability in the core of a high-power sodium-cooled fast reactor (of the BN-type) without feedbacks. The importance of this problem for high-power BN-type reactors is associated with the specific features of the ...

Kinetics equations for neutron distributions [PDF]

open access: yesJournal of Nuclear Energy. Parts A/B. Reactor Science and Technology, 1965
Abstract Kinetic equations for neutrons and some of the other kinds of particles important to neutron balance in reactors and reactor-like systems are derived from a quantum Liouville equation. In particular, equations for some of the relevant singlet and doublet densities in phase space are deduced for the purpose of studying neutron density ...
