摘　　要：采用一体化分析程序建立了适用于CANDU堆核电厂的严重事故分析模型。该模型主要包括热传输系统、慢化剂系统、端屏蔽系统、蒸汽发生器二次侧系统等。针对全厂断电始发的严重事故进行了相应的热工水力现象分析,得知慢化剂系统和端屏蔽系统内的大量水使事故进程大幅推迟。同时,对重要时间进程与ISAAC2.0程序结果进行了初步比对,两者的结果基本吻合。分析结果可为开展重水堆严重事故现象及缓解措施研究提供技术参考。With an integral system analysis code,the analysis model for CANDU station was built,which contains the primary heat transfer system,calandria system,end shield system and the secondary side of steam generators.The station blackout accident was selected to make further thermal-hydraulic analysis.The comparison of the results with ISAAC2.0code was performed,and it shows that timing of the major events is fairly close.
