| 摘 要： | 基于环形燃料元件，提出了一种超高通量堆(UFR)堆芯概念设计。UFR燃料组件设计采用61个燃料元件构成的六角形组件，堆芯采用52盒燃料组件、9盒控制棒组件和厚反射层设计。通过开展堆芯概念设计方案评价，给出了堆芯循环长度、中子注量率、中子能谱、中子空间分布等关键参数。结果表明，在当前的总体参数下所提出的UFR的最大中子注量率可达到1.0×1016 cm-2·s-1。

| Abstract: | Based on the annular fuel elements, a conceptual design of ultra-high flux reactor (UFR) is proposed. The fuel assembly design adopts a hexagonal assembly composed of 61 fuel elements. The core is designed with 52 boxes of fuel assemblies, 9 boxes of control rod assemblies and a thick reflecting layer. The key parameters such as the core cycle length, neutron fluence rate, neutron energy spectrum and neutron spatial distribution are given from the evaluation of the core conceptual design scheme. The results show that the maximum neutron fluence rate of the proposed ultra-high flux reactor can reach 1.0 × 1016 cm?2·s?1 under the current general parameters. |
