建立了利用WIMS＋CITATION计算医院中子照射器I型堆堆芯中子学参数的模型，计算了堆芯的功率分布、 顶铍反应性价值、控制棒价值、温度系数、堆芯燃耗等中子学参数，计算结果与文献数据一致，表明文章所建立的计算模型可用于医院中子照射器I型堆堆芯的物理计算。

Using WIMS & CITATION program, the neutronic parameters calculating model of in-hospital neutron irradiator mark 1(IHNI-1) reactor is presented in this paper.The power distribution, reactivity worth of control rod and top beryllium, temperature coefficient and burnup are calculated. It proves that the results are consistent with the literature values and the method is appropriate to physical calculation of IHIN-1 reactor.
