摘要: COSINE是我国首个完全自主开发的用于核反应堆设计与安全分析的软件包,其系统分析程序具有保守模型与最佳估算模型两个版本。依据国际最新的评价模型开发与评估方法——EMDAP方法,对COSINE系统程序的保守模型和应用于最佳估算大破口失水事故(LOCA)事故分析的最佳估算模型所需评估的重要现象和过程进行识别和排序,制定出大破口LOCA事故PIRT表。同时,根据模型评估需求,构建核电软件模型评估数据库。

Abstract: COSINE is the first software package for the nuclear power plant design and analysis developed in China. The system analysis code of COSINE has two versions, one is the conservative model version and another is the best-estimate model version. According to the latest evaluation model development and assessment methodology-EMDAP method, the important phenomenon and process to be evaluated by the conservative model and the best estimation model for the large break LOCA of COSINE system code are identified and ranked, and a PIRT table of large break LOCA has been made. At the same time, according to the assessment requirement, a nuclear power software evaluation database is constructed.
