Abstract

A multi-physics coupling system has been developed in this work based on the MOOSE framework for the steady-state analysis of XAPR (Xi’an Pulse Reactor). It consists of three physical models including neutronics, thermo-mechanics model of fuel element and fluid flow model. These models have been coupled by Picard iteration through the MultiApp and Transfer system based on MOOSE framework. The core state parameters of XAPR under steady-state operation condition are analyzed and the 3-dimensional space-dependent power density, fuel element temperature as well as the coolant temperature are provided by the multi-physics model. The multi-physics model successfully reproduced the experimental results of the monitored fuel element temperature in XAPR under different power level, and the deviation was less than 20 K. Future work would be to study the dynamics behavior of XAPR to further validate the multi-physics model and simulate other advanced micro reactors.

基于多物理场耦合方法的西安脉冲反应堆稳态分析

本研究基于 MOOSE 框架开发了一个多物理场耦合系统，用于 XAPR（西安脉冲反应堆）的稳态分析。该系统由三个物理模型组成，包括中子学模型、燃料元件热力学模型和流体流动模型。这些模型通过基于 MOOSE 框架的多应用和传输系统进行 Picard 迭代耦合。多物理场模型分析了稳态运行条件下 XAPR 的核心状态参数，并提供了三维空间功率密度、燃料元件温度和冷却剂温度。多物理场模型成功再现了不同功率水平下 XAPR 中燃料元件温度监测的实验结果，偏差小于 20 K。未来的工作将是研究 XAPR 的动力学行为，以进一步验证多物理场模型，并模拟其他先进的微型反应堆。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
