摘要: 为了优化压水堆核电厂装换料工艺流程,提高装换料效率,分别建立了装卸料机、水下燃料运输系统、燃料抓取机等设备的运动学模型,并根据模型推导出计算装换料操作总时间的初步方程,形成反应堆装换料操作流程参数化分析的方法。通过对某典型堆型进行参数验证,证明了该模型和方法的正确性和有效性。Abstract: In order to optimize the refueling operation and improve the efficiency of the pressurized water reactor nuclear power plants, kinematic models of the main refueling equipment such as refueling machine, underwater fuel transfer system and fuel handling machine are established, respectively. General formulas for total time of reactor refueling are derived based on the models. The parametric analysis method for refueling operations is developed. Finally the models and methods are proved to be proper and effective by the parameter calibration of a typical reactor.
