Special Issue Information

Dear Colleagues,

We invite you to submit your original research or review papers to this Special Issue of Energies on “Advances in Modeling for Nuclear Science and Engineering”.

Computer models have played a central role in assessing the functioning of nuclear power facilities for decades. They have ensured that nuclear operations are efficient, but also safe to both the public and the environment. The field of nuclear engineering is complex and multi-physics in nature, spanning the fields of neutron transport, thermal hydraulics, structural mechanics, heat transfer, and chemistry. Robust, accurate, and validated models are essential to the areas of rector design, operation and procedure analysis, fuel optimization, and lifetime extension, among others. Nuclear engineering research has been a significant contributor to the field of numerical analysis and modeling by advancing areas in predictive multi-physics modeling, sensitivity and uncertainty quantification, high-fidelity discretizations, reduced-order models, artificial intelligence, and HPC.

This Special Issue aims to bring together studies describing recent advances in modeling methods for all areas in nuclear engineering applications. We welcome contributions from academia and industry in the aforementioned fields.

The application of continuous and discontinuous approaches of the finite element method (FEM) to the neutron transport equation (NTE) has been investigated. A comparative algorithm for analyzing the capability of various types of numerical solutions to the NTE based on variational formulation and discontinuous finite element method (DFEM) has been developed. The developed module is coupled to the program discontinuous finite element method for neutron (DISFENT). Each variational principle (VP) is applied to an example with drastic changes in the distribution of neutron flux density, and the obtained results of the continuous and discontinuous finite element (DFE) have been compared. The comparison between the level of accuracy of each approach using new module of DISFENT program has been performed based on the fine mesh solutions of the multi-PN (MPN) approximation. The obtained results of conjoint principles (CPs) have been demonstrated to be very accurate in comparison to other VPs. The reduction in the number of required meshes for solving the problem is considered as the main advantage of this principle. Finally, the spatial additivity to the context of the spherical harmonics has been implemented to the CP, to avoid from computational error accumulation. Full article

The below list represents only planned manuscripts. Some of these manuscripts have not been received by the Editorial Office yet. Papers submitted to MDPI journals are subject to peer-review.

Title: Enhancement of CMFD Schemes with Optimal Relaxation
Authors: Dean Wang; Zuolong Zhu
Affiliation: The Ohio State University
Abstract: In this paper, we perform a comprehensive Fourier analysis to find optimal relaxation for various CMFD type schemes to enhance their performance, including the standard CMFD, pCMFD, odCMFD, and lpCMFD. Numerical results are presented to verify the theoretical Fourier analysis.
