摘　　要：为将多用途模块式先进小型压水堆(ACP100)堆芯换料周期提升至24个月,兼顾良好的燃料利用率并保证功率展平特性满足安全性的限值要求,本文使用具备工程经验的成熟软件,进行不同的批料数、不同富集度组合、不同径向装载模式等组合方案的燃料管理研究,通过研究掌握了不同策略特征并形成ACP100堆芯燃料管理推荐策略:选取3批次换料、24盒组件/批的倒料策略,结合部分低泄漏装载模式,作为ACP100堆芯燃料管理推荐策略,同时进一步提高燃料富集度以提升燃料经济性。In order to achieve 24-months cycle length for Advanced Small Modular Pressurized Reactor （ACP100）, and keep a balance between good fuel utilization and fiat power distribution to assure reactor safety, using the well-developed software applied in engineering practice, this paper construct cases with combination of different number of assemblies per batch, enrichment types, and radial loading patterns; characteristics analysis of these cases could be referred during the confirmation of fuel management strategy of ACP100 reactor, and a recommended strategy is attained： combination of 3 batch loading and 24 assemblies per batch, along with partial low leakage loading pattern, and a higher enrichment to improve fuel economics.
