摘要

液态铅铋合金(Lead Bismuth Eutectic

LBE)自然循环流动的研究，有助于解决加速器驱动的次临界反应堆(Accelerator Driven Sub-critical systems

ADS)中冷却剂的流动稳定性及传热问题。运用析因分析方法，分析液态铅铋合金自然循环流动的不同影响因素及其因素间交互作用。结果显示，在对流速的影响中，管径大小影响所占的百分比贡献率最大，其次是温差的影响，之后是温差和管径交互的影响，最后是高度差和管径的交互影响。其他因素及其他因素间交互作用对流速的影响可以忽略不计。

Abstract

Background: The study of natural circulation of Lead Bismuth Eutectic (LBE) has great significance for the Accelerator Driven Sub-critical systems (ADS). Purpose: This study aims to analyze the factors and the interaction between different factors on natural circulation flow of LBE. Methods: Based on the previous experimental results obtained by ADS team

the factorial analysis method is applied to study the steady flow of lead bismuth eutectic under natural circulation using typical data. Results: The pipe diameter size accounts for about 65.94% of the total influence on the steady state flow whilst the temperature difference accounts for 16.89%

the temperature difference and tube diameter interaction accounts for 7.44%

the height difference and tube diameter account for 2.7%. Conclusion: The pipe diameter size is the most important influence factor of the steady flow of lead bismuth eutectic

much larger than all others such as temperature difference

interaction between temperature difference

tube diameter

and the interaction between height difference and tube diameter. Abstract
