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.
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.
