PELAP5程序是进行核电厂系统热工水力瞬态及事故分析的重要工具。为保证秦山和广东核电厂事故分析审核计算的顺利进行,充分发挥RELA P5程序在我国核电安全分析中的作用。提高程序应用的方便性,我们按照程序开发合同的要求,完成了规定的攻关目标和内容。主要内容有:掌握稳态初始化的有效步骤和方法,通过设置合理的稳态控制系统,
The PELAP5 program is an important tool for thermal-hydraulic transient and accident analysis of nuclear power plant systems. In order to ensure the smooth progress of audit and calculation of accident analysis of Qinshan and Guangdong Nuclear Power Plants, give full play to the role of RELA P5 program in China’s nuclear power safety analysis. To improve the convenience of application of the program, we completed the stipulated goals and contents of the research according to the requirements of the contract of program development. The main contents are: to master the effective steps and methods of steady-state initialization, by setting a reasonable steady-state control system,
