摘要/Abstract

摘要： 压水堆堆芯的运行瞬态和事故瞬态是伴随着复杂的热工水力过程的三维中子动力学问题。为了改进现代压水堆的安全设计,提高核电厂运行的机动性和经济性,对这类问题作直接的三维分析是必要的。然而,这种分析常常要花费很大的计算代价。因此,发展既有适当精度又能快速求解的三维模型和相应的计算机程序,就成为使这种计算分析具有工程实用价值的重要途径。SNENM/RTSP程序正是为了满足这种要求而研制的。

Abstract: The paper introduces a three-dimensional nodal and subchannel analysis code package for the core transient in PWPs-SNENM/RTSP, including the model of neutronics and thermohydraulics used in the package. The preliminary results of applying this code package to the analysis of Steam-Line Break accident for Qinshan NPP are given and also evaluated briefly.

Key words: core transient analysis, 3D nodal method, subchannel model, steam-line break
