摘要
AP1000堆芯首循环装料采用5种富集度的组件,使用IFBA、WABA可燃毒物,且部分组件两端设有轴向再生区,堆芯布置复杂。本文采用SCALE程序系统中三维蒙特卡罗输运程序KENO及二维离散纵标程序NEWT,进行了典型燃料组件的栅格物理计算。研究了深燃耗下不同富集度栅元、燃料组件无限增殖因子(kinf)及主要可燃耗核素核子密度随燃耗的变化规律,得到了AP1000典型燃料组件深燃耗物理特性。
In the first cycle loading of the AP1000 reactor, assemblies with five kinds of enrichments and burnable poisons such as IFBA, WABA are employed. For some assemblies, there are regeneration blankets at both ends. All these make the core arrangement extremely complex. The lattice physics calculation was performed using the KENO 3-D Monte Carlo criticality computer code and NEWT multigroup discrete ordinates radiation transport code of SCALE code system. The kinf and atomic number density of typical isotopes as a function of burnup for different enrichment fuel cells and fuel assemblies were studied on the condition of the deep burnup, and the physical characteristic of AP1000 assembly was concluded.
