Linear stability analysis of a nuclear reactor using the lumped model [PDF]
Nuclear Technology and Radiation Protection, 2016 The stability analysis of a nuclear reactor is an important aspect in the design and operation of the reactor. A stable neutronic response to perturbations is essential from the safety point of view. In this paper, a general methodology has been

USING PROMPT NEUTRON DECAY CONSTANT MEASUREMENTS TO OBTAIN ADDITIONAL KINETICS INFORMATION [PDF]
EPJ Web of Conferences, 2021 Prompt neutron decay constant measurements are typically used to infer the prompt neutron lifetime in a chain-reacting system, but these measurements include much more information about the kinetics of the system.

Solution for the Multigroup Neutron Space Kinetics Equations by Source Iterative Method
Brazilian Journal of Radiation Sciences, 2021 In this work, we used a modified Picard’s method to solve the Multigroup Neutron Space Kinetics Equations (MNSKE) in Cartesian geometry. The method consists in assuming an initial guess for the neutron flux and using it to calculate a fictitious source ...

GEN-FOAM MODEL AND BENCHMARK OF DELAYED NEUTRON PRECURSOR DRIFT IN THE MOLTEN SALT REACTOR EXPERIMENT [PDF]
EPJ Web of Conferences, 2021 The effective delayed neutron fraction is an important reactor kinetics parameter. In flowing liquid-fuel reactors, this differs from the delayed neutron fraction because of the emission of delayed neutrons with a lower energy spectrum than prompt and ...

Neutron Density Calculation Using the Generalised Adams-Bashforth-Moulton Method
Universitas Scientiarum, 2019 This paper presents a numerical solution to the equations of point kinetics for nuclear power reactors, a set of seven coupled differential equations that describe the temporal variation of neutron density and the concentration of delayed neutron ...

The lifetime distribution of finite fission chain group around the prompt criticality
Nuclear Analysis, 2023 In order to describe the behavior of finite fission chains in a fission system initiated by a δ neutron source, we present the conception of the finite fission chains group (FFCG).
