摘　　要：通过计算热中子利用率来估算靶件对堆芯反应性的影响,同时使用燃料管理程序进行校算。估算结果表明,堆芯80盒元件可装氮化铝靶料4000 g,对反应性的影响约为-250×10-5,使堆芯寿期缩短约60MW·d;14C的年产量可达1.0×1012 Bq。高通量工程试验堆(HFETR)的堆芯核设计和运行结果表明,该估算是正确、合理的。The core reactivity change from AIN targets and 14C producing rate is estimated by calculating the using distribution of reactor neutron, while the fuel management code of HFETR is used to contrast with the estimation calculation. The calculation result shows that it causes about 250× 10.5 reduction of reactivity and core life will be cut down about 65 MW-d when all the 80 fuel assembly center holes are filled with 4000 gram AIN targets, while 1.0× 1012 Bq 14C could be produced per year. The estimation results accord well with HFETR reactor core design and operation status.
