摘　　要：针对将水力驱动控制棒系统应用于可移动海水淡化装置时可能会遇到的失重、超重等问题,该文模拟装置以不同方式变速上升或下降较大距离,建立理论模型分析控制棒的运动特性。通过对计算结果进行分析,得出不同温度、流量下水力驱动控制棒系统不出现异常提棒现象的临界加速度。结果表明,对于200MW低温核供热堆装置,可移动海水淡化装置的上升和下降加速度均应小于0.112g。In a portable seawater distillation system, the hydraulic control rod drive system may experience an abnormal condition of weightlessness or excess weight. A theoretical model was developed for a portable seawater distillation system that may move long distances upward or downward with nonuniform velocities. The model was then used to analyze the behavior of the hydraulic control rod drive system. The critical acceleration for the control rod not to move up or down abnormally was determined using the model. The results show that the acceleration for the desalination system to move up and down should be less than 0.112 g with a 200MW lowtemperature nuclear heating reactor being used.
