摘要
严重事故过程可分为堆芯解体、压力容器熔穿、安全壳失效三阶段,裂变产物随之释放。严重事故分析程序有两类,系统性程序与机理性程序。系统性程序能计算完整的事故序列,机理性程序偏重事故进程的局部细节。主要介绍系统性程序STCP、MELCOR、ASTEC与机理性程序RELAP5/SCDAP、VICTORIA、CONTAIN。
Based on the progression, the phenomena in a severe accident are classified into three phases: core degradation, vessel melt-through and the failure of the containment, and the fission products were released there after. The codes used for severe accident analysis fell into two categories: integrated codes and mechanistic code. Integrated codes aimed at calculating complete accident sequences. Mechanistic codes pay more attention to details and often considered a particular part or phase of an accident sequence. Integrated codes STCP, MELCOR, ASTEC and mechanistic codes RELAP5/SCDAP, VICTORIA, CONTAIN are described.
