摘要: CF3燃料组件是我国自主研发的大型压水堆燃料组件，其将用于“华龙一号”反应堆，支持“华龙一号”的出口。为了满足“华龙一号”反应堆的要求，在商业堆上开展了CF3先导组件的辐照考验，通过池边检查获取了燃料元件堆内数据，并基于堆内数据进行了模型开发，建立了适用于CF3燃料元件的性能分析程序，基于此针对“华龙一号”反应堆的需求，对CF3燃料元件的性能进行了预测。分析结果表明，CF3燃料元件满足“华龙一号”反应堆设计要求。Abstract: CF3 fuel assembly is an independently developed large PWR fuel assembly in China, which would be loaded in HPR1000, and support HPR1000 outlet. In order to meet the requirements of HPR1000 reactor, the irradiation test of the CF3 pilot assembly was carried out on the commercial reactor. The fuel element in-reactor data was obtained through the pool-side inspection, and the model was developed based on the in-reactor data. The performance analysis program suitable for the CF3 fuel element was established. Based on this, the performance of CF3 fuel element is predicted according to the demand of HPR1000 reactor. The analysis results show that the CF3 fuel element meets the design requirements of HPR1000 reactor.
