Abstract

In this paper, low-temperature experiments are carried out on the visualized experimental device to study the melting behavior of plate-type fuel in severe accidents of the reactor. In the experiments, the plate-type fuel with different sizes made of nickel–chromium alloy, zinc and aluminum was used to carry out the visualized experiments in air, argon, and vacuum environment. It was found that both the size of the plate and the experimental environment have a significant influence on the melting behavior in this study. And the temperature distribution, melting behavior characteristic, the key parameters such as blistering position, blistering size, breaking position and breaking size were also obtained. Based on the experimental data, the physical phenomena and processes related to the blistering and melting of the fuel plates are analyzed in this paper, which provides experimental data support for the development of analysis model and formulating perfect mitigation strategies for severe accidents.

基于替代材料的板式燃料熔化行为实验研究

本文在可视化实验装置上进行了低温实验，以研究反应堆严重事故中板式燃料的熔化行为。实验中，使用了由镍铬合金、锌和铝制成的不同尺寸的板式燃料，在空气、氩气和真空环境下进行了可视化实验。研究发现，板的尺寸和实验环境对熔化行为都有显著影响。同时还得到了温度分布、熔化行为特征、起泡位置、起泡尺寸、断裂位置和断裂尺寸等关键参数。本文以实验数据为基础，分析了与燃料板起泡和熔化相关的物理现象和过程，为建立分析模型和制定完善的严重事故缓解策略提供了实验数据支持。

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.
