海洋条件下核动力装置自然循环流动特性的无量纲分析

利用无量纲分析法推导出海洋条件下核动力装置的自然循环流量表达式,导出了稳态自然循环流量方程,结果与实验值吻合.以自然循环流量的波动不引起功率调节系统动作为限制条件,采用无量纲分析法推导出此条件下摇摆振幅与摇摆周期的关系式;两者呈二次函数关系,理论计算结果与大型分析程序的计算结果吻合.功率调节系统动作与否取决于最大摇摆角加速度的大小,而与最大摇摆角速度无关.

Dimensionless Analysis of Natural Circulation Characteristics of Nuclear Installations under Ocean Condition

The dimensionless analysis is used to deduce the expression of natural circulation flow of nu-clear installations under ocean condition and the natural circulation flow equation in the steady state. The theoretical results are consistent with the experiment values. The expression between rolling amplitude and rolling period is also been deduced by the dimensionless analysis, with the limit that the fluctuation of natural circulation flow cannot cause the response of the control rods. The relation between th...
