SCDAP/RELAP5程序结构及严重事故有关的模型概述

Code Structure and Severe Accident-related Models of SCDAP/RELAP5 MOD3 Program

SCDAP/RELAP5 MOD3是目前国际上通用的机理性严重事故分析程序,可用于严重事故下堆芯损坏进程的的详细分析以及严重事故管理策略的设计与评估。介绍了SCDAP/RELAP5 MOD3程序的主体结构,RELAP5与SCDAP之间的联系,并分类说明了SCDAP程序的堆芯损坏进程模型以及实施模型的主要子程序。

This paper analyzes the main code structure of SCDAP/RELAP5 MOD3 program and the relationships between SCDAP and RELAP5. Physical models for severe core damage progression and the subroutines of the program in which these models implemented are presented also.
