摘　　要：在一维扩散模型的基础上,建立了放射性核素在水质中的瞬态三维扩散模型,并给出了瞬态排放模式下模型的计算公式,实现了水质中放射性核素扩散浓度的快速估算.在MATLAB程序下,利用该方法对一个实例进行了仿真分析,得出相关结论,对于核泄漏事故下放射性核素扩散浓度预测评估及制定安全措施具有指导意义.Transient model of 3_dimension diffusion of radionuclide in liquid was established on the basis of 1_ dimension diffusion model. And computation formula of the model in transient drainage mode was figured out, which can rapidly evaluate concentration distribution of radionuclide in liquid. An example was simulated and analyzed in MATLAB program by the means of the method. Some conclusions are drawn, which are significant and important to forecast and evaluate the radio-nuclides diffusion and to provide safety rules after radio- nuclides leak.
