摘要
研究评价了秦山第二核电厂2号机组第11-13循环中进行入堆辐照考验的4组CF3先导燃料组件的主要性能,包括包壳腐蚀、燃料棒生长、燃料组件生长等,并与首循环池边检查结果进行对比。结果表明CF3先导燃料组件主要堆内性能符合预期,与预测值相比有更高的裕量,现有辐照性能分析模型可进一步改进后用于后续工程评价。
The performance, including fuel rod corrosion, cladding growth and fuel assembly growth, of four group CF3 leading fuel assemblies in Qinshan- 11 Nuclear Power Plant unit 2 from cycle I 1 to cycle 13 are studied and compared to 1 st cycle irradiation of CF3 fuel assemblies. The results show that the irradiation performance of CF3 fuel assemblies are performing as expected and have more margin than the predicted value. The existing irradiation performance model can be used in the engineering design with further development.
