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。
For the CF2 series fuel assemblies, the 1: 1 high temperature and high pressure flushing test of full scale and truncated (applied to the modular stack) components was carried out respectively to test the reliability of CF2 series fuel assemblies and the reliability of the CF2 series fuel assemblies. Abrasion resistance and other conditions, get the control rod in the full-size and short-cut component falling stick performance data, and discusses the erosion test parameters to determine the working conditions. The results provide an important experimental basis for the design optimization, safety assessment and application of domestic advanced fuel assemblies.
