摘　　要： 针对CF2系列燃料组件,采用全尺寸和截短型(应用于模块化小堆)整组件分别开展了1:1的模拟燃料组件高温高压冲刷试验研究,考验了CF2系列燃料组件结构的可靠性及耐磨蚀等情况,获得了控制棒在全尺寸和截短型组件内的落棒性能数据,同时探讨了冲刷试验的工况参数确定方法。研究结果为国产先进燃料组件设计优化、安全评定及应用提供了重要的试验依据。 A full size and truncated （used in small modular reactors） CF2 fuel assembly were adopted in the hot rushing test. The experiment was carried out in the condition of high temperature and pressure, where the components of the driving line were simulated as 1：1. The reliability and anti-abrasion of fuel assembly was tested. The dropping performance data were obtained for the two sizes of fuel assembly. Moreover, the method of rushing test was also discussed in this paper. It provided an important experimental basis for the optimization design, safety assessment and aoolication of domestic advanced fuel assembly.
