摘　　要：计算机仿真对核反应堆运行和核电人员的培训具有十分重要的意义。基于Simulink仿真软件,本工作对点堆中子动力学方程输入阶跃反应性考虑6组缓发中子时具有温度和毒物反馈的特性进行研究,计算了某型反应堆在两种典型工况下引入正、负阶跃反应性时各主要运行参数的变化规律,并将最终的结果与三维模型计算数据进行了对比。结果表明:利用Simulink进行点堆仿真研究能够高效、便捷地满足系统要求,且仿真结果与三维模型计算的数据符合得较好。The computer simulation has very important significance for reactor operation and training operators.Based on Simulink,the characteristics of point-reactor neutron kinetics equation with six-groups delayed neutron were researched when a step reactivity was inserted in the reactor with temperature and poison feedback.Main parameters of a certain reactor were calculated under two typical operating conditions with positive and negative step reactivity.The results were compared with those obtained by 3-D simulation software of reactor.It is shown that the system requirement can meet efficiently and rapidly with Simulink.
