摘　　要：针对先进核能系统发展需要,提出了超高通量堆的堆芯概念设计。本文采用板型燃料、正方形燃料组件设计,设置宽流道保证堆芯冷却剂占有较高的体积份额。堆芯采用52盒燃料组件,设置8盒控制棒组件和较厚的反射层。通过堆芯概念设计方案评价,结果表明堆芯循环长度可达100EFPD(等效满功率天),所提出的超高通量堆的最大中子注量率可达到1.08×10^(16)cm^(−2)·s^(−1)。To meet the development need of advanced nuclear systems,an ultra-high flux reactor(UFR)core design concept is proposed in this paper.In this concept,plate-type fuel and square fuel assembly design is adopted,and a wide flow channel is provided to ensure a high volume share of the core coolant.The core is provided with 52 boxes of fuel assemblies,8 boxes of control rod assemblies and a thick reflective layer.The results show that the cycle length of the core can reach 100 equivalent full power days(EFPD)by the core conceptual design scheme evaluation.The maximum neutron fluence rate of the proposed ultra-high flux reactor can reach 1.0×10^(16)cm^(−2)·s^(−1).
