【摘要】 控制棒落棒性能试验是秦山核电二期工程反应堆控制棒驱动线热态综合试验一个重要组成部分。采用VXI数据采集系统,测量落棒时间,通过对位置指示器初级及次级线圈的感应电势的测量,拟合出了棒位-时间曲线、速度-时间曲线及加速度-时间曲线。测量结果表明,包括落棒时间在内的各种性能参数均满足试验要求。更多还原

【Abstract】 The measurement of rod drop property parameters is an important component in Rod Drop Property Parameters Measurement of Control Rod Drive Line Hot Comprehensive Test for Qinshan PhaseⅡ NPP Project. VXI data acquisition system is used to measure the drop time, the voltage of the primary coil and the second coil of the rod position detector, the imitate dropping rod position versus time curve, dropping rod speed versus time curve and dropping rod acceleration versus time curve. The result of measurement proves that the drop property parameters meet the requirements of the design specification for Control Rod Drive Line.更多还原
