Study on Scaling Law of PWR Natural Circulation with Motion Condition

National Key Laboratory of Bubble Physics and Natural Circulation, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 对于安装在车、船或艇上的压水反应堆进行运动状态下的模拟试验研究,是研究其安全性的重要手段。以静止状态的反应堆自然循环比例模拟方法为基础,通过刚体运动理论获得运动装置上各点的加速度,然后带入动量方程加速度项,从而获得运动相似准则数。在此基础上,分析了等高度和变高度模拟方法,其中,变高度模拟涉及位移与角加速度等运动变量的不等时性,需要注意。

Abstract: For some nuclear reactors installed on automobiles,boats or deep sea vehicles,it is an impor-tant way to investigate their system safety by performing natural circulation experiments under motion condi-tion.This paper studied the natural circulation on moving plants based on work of static natural circulation scaling method.With rigid motion theory,acceleration at each point was obtained on primary system and introduced to momentum equation.Thus a set of motion similar criteria were obtained.Furthermore,equal and unequal height simulation were analyzed.As to the unequal one,non isochronous simulation was needed for displacement and angular acceleration.
