压水堆核电站严重事故紧凑型仿真机开发

为了缓解压水堆核电站可能发生的严重事故的后果，也为了满足安全分析工程师和概率风险评价人员的需求，并在与国际原子能机构合作框架协议内，研制开发了紧凑型的严重事故仿真分析机MELSIM－PC。该仿真系统主要由仿真核心程序、同步通讯程序、人机界面程序等几个部分组成，可以工作在一台普通的微型计算机上，成功地实现MELCOR程序变量的运行数据库管理、电站动态图形显示、仿真计算控制、再启动和仿真重演等重要功能。

Development of A Compact Severe Accident Simulator for PWR Nuclear Power Plants

In order to alleviate the consequence of a possible severe accident in PWR Nuclear Power Plants and in response to the demands of safety analysis engineers and Probabilistic Safety Assessment(PSA) specialists,a compact severe accident simulator has been developed under an IAEA TC project.The PC-based simulator consists of the database engine MELCOR code,the man-machine interface modules MANAGER ＆ DISPLAY,the communication module SERVER and the supplementary modules.It can be used successfully to realize some very important functions,such as the variable database management of MELCOR code,the plant mimic screens,simulation computation control,restart and replay,etc.
