高通量工程实验堆（HFETR）具备复杂的组件几何结构，且堆芯布置的非均匀性很强。相对于传统压水堆，此种特点对 HFETR的堆芯计算和燃料管理提出了更高的要求。因此，开发了基于传统两步法的新的燃料管理计算平台HEFT。HEFT组件计算采用HEFT-lat程序，可实际描述HFETR的组件几何，减小组件计算时几何近似带来的误差。堆芯计算采用三角形节块三维SN 输运程序DNTR。验证结果表明：HEFT对于 HFETR的堆芯模拟具有较高的精度，可满足工程计算的需求。

The High Flux Engineering Test Reactor (HFETR) is loaded with complex geometry assemblies ,taking on strong heterogeneity .These features call for more advanced core analysis and fuel management methodologies compared with traditional PWR . Based on the two-step method , a fuel management simulation platform HEFT was developed .In HEFT ,the lattice code HEFT-lat has the abilities to describe complex assembly geometries of HFETR , whereby mitigate errors brought by geometrical approximations .DNTR ,a triangular mesh nodal SN method code ,was employed to solve the transport equation . The good agreements between simulation results and experimental ones show that HEFT can meet the demand of engineering simulations .
