径向倒料式驻波堆堆芯概念设计

本工作在综合分析日本CANDLE堆和美国TerraPower公司设计的TP-1堆的基础上，提出沿径向倒料的驻波堆堆芯设计初步方案，通过高、低富集度组件在堆芯的混合布置展平功率，降低了堆芯的功率峰因子和组件的最大燃耗深度。通过倒换料，实现了增殖 燃耗波的传递。为能有效地利用行波堆增殖产生的易裂变核素，采用更换包壳的新技术，实现核燃料的持续利用。

Conceptual Core Design of Standing Wave Reactor With Radial Fuel Shuffling Scheme

On the basis of CANDLE reactor in Japan and TP-1 reactor designed by TerraPower in USA, a conceptual core design of standing wave reactor with radial fuel shuffling scheme was proposed. The core power peaking factor and the maximum burnup of assemblies were reduced by mixed arrangement of high and low enrichment assemblies in the core. Through the radial shuffling scheme, the breading-burnup wave propagation was achieved. In order to utilize the fissile material produced by standing wave reactor, the fuel cladding reprocessing technique was applied, and the sustainable utilization of nuclear fuel was realized.
