摘　　要：利用蒙特卡罗程序(MCNP)对第一代医院中子照射器(IHNI-1)进行了部件反应性价值的微扰计算,模拟计算了中央控制棒、辅助控制棒、上铍反射层、燃料棒等部件的反应性价值,分析比较了理论值与实验值之间的差异。结果表明,IHNI-1堆部件反应性价值的理论值与实验值基本符合,微扰方法的计算精度满足堆芯部件反应性价值的计算要求。The perturbation calculation for the reactivity worth of the components in the first In-Hospital Neutron Irradiator （IHNI-1） was conducted by using MCNP Monte Carlo code （MCNP）, and the reactivity worth of the central control rods, auxiliary control rod, upside Be reflection layer and fuel elements were reasonably calculated. The difference between the calculated value and experimental value was analyzed. The results showed that the calculated value agreed with the experimental value for the components of IHNI-1 reactor, and the calculation precision of the perturbation method meets the requirement on the calculation of reactivity worth of the reactor components.
