结合辐照考验方案，评价了CF₂先导燃料组件的机械性能及燃料棒的热力性能，结果表明各项性能均满足准则要求。结合辐照后池边检查结果，对CF₂燃料组件的主要堆内辐照性能进行了研究，包括燃料组件及燃料棒生长和弯曲、定位格架生长等各项燃耗相关性能。结果表明，在燃耗达到44500 MWd/tU的情况下CF₂燃料组件主要辐照性能均达到了预期水平，满足反应堆的使用要求。CF₂燃料组件后续可批量应用于华龙一号。

The mechanical performance of CF₂ lead fuel assembly and the thermal-mechanical performance of the fuel rod are evaluated considering the irradiation condition of the irradiation program and the criteria are fulfilled. The major in-pile performance of CF₂ fuel assembly are studied on the basis of the poolside examination results, including the burnup dependent parameters such as the growth of fuel assembly and fuel rod, the bow of fuel assembly and fuel rod, the growth of grid, etc. The results show that the major in-pile performance of the CF₂ fuel assembly has reached the expectations, and the fuel has fulfilled the requirements of the reactor system.
