摘要: 根据西安脉冲堆工程的实际需要,研制了脉冲堆堆芯燃料管理计算软件包HEX ICFM,并建立了正交优化模型,研制了换料优化计算软件包HEX ORTH.软件包中栅元计算采用了WIMS D 4程序,堆芯扩散计算程序采用了二维六角形节块程序SIXTUS 2.应用HEX ICFM对西安脉冲堆首循环堆芯参数进行了计算,并用HEX ORTH对第3循环末堆芯燃料装载和30根备用新燃料元件进行了堆芯优化分析,得到了目标函数为max(KeffBOC)的最佳堆芯倒换料方案.

Abstract: An in-core fuel management code package HEX-ICFM is developed for Xi'an Pulsed Reactor.The orthogonal design model and the loading pattern optimization program HEX-ORTH are studied.The cell calculation is performed using WIMS-D/4.A two dimensional hexagonal geometry multigroup nodal theory code SIXTUS-2 is used for core diffusion calculation.The core physical parameters are calculated using HEX-ICFM for the first cycle of Xi'an Pulsed Reactor.With the fuel of end of cycle 3 and 30 fresh fuel rods the optimum loading patterns are calculated for the objective function max(KBOCeff)using HEX-ORTH.

Key words: Xi'an pulsed reactor, in-core fuel management, orthogonal design method, optimization
