Monte Carlo simulation of fast neutron-induced fission of ²³⁷Np *

Abstract

The potential-driving model is used to describe the driving potential distribution and to calculate the pre-neutron emission mass distributions for different incident energies in the reaction. The potential-driving model is implemented in Geant4 and used to calculate the fission-fragment yield distributions, kinetic energy distributions, fission neutron spectrum and the total nubar for the reaction. Compared with the built-in G4ParaFissionModel, the calculated results from the potential-driving model are in better agreement with the experimental data and evaluated data. Given the good agreement with the experimental data, the potential-driving model in Geant4 can describe well the neutron-induced fission of actinide nuclei, which is very important for the study of neutron transmutation physics and the design of a transmutation system.

Monte-Carlo calculation of fission process for neutron-induced typical actinide nuclei fission

“…In the processes of neutron-induced actinide nuclei fission, the specific compound nucleus takes place deformation, when the deformation is large enough, the specific compound nucleus breaks up into two fragments at the scission point. In this work, we attempt to propose empirical fission potentials to drive to calculate the preneutron-emission mass distribution [7]. The potentialdriving model can describe the driving potential D of a fissile system around the scission point by sum of a symmetric fission potential and asymmetric fission potentials.…”

“…Based on the potential-driving model, Monte Carlo code, Geant4, simulates the 14 MeV fast neutron-induced actinide nuclei fission [7,18]. The fission process involves two continuous processes (a) the creation of fission reaction and (b) the unstable fission fragments refund excitation process, which are taken in account in the Geant4 physical model [19].…”

“…We have developed a global potential-driving model by uniting the empirical asymmetric fission potential and the empirical symmetric fission potential to precisely calculate the pre-neutron-emission mass distributions for neutron-induced actinide nuclei fission [7]. In this work, based on the developed potential-driving model, Monte-Carlo code calculates the characteristics of fission reaction process for neutron-induced typical actinide nuclei 241 Am fission.…”

The Usage of Monte Carlo Simulation to Predict The Sales of Sustainable Batik Products in Small Medium Enterprise

“…The basis of the Monte Carlo method is the experimentation of various possible elements using a random sample. The advantage of the Monte Carlo method is that it is a powerful numerical calculation tool for simulating statistical data, this simulation obtains accuracy values accurately from the physical form of the observable system (Liu et al, 2019).…”
