Abstract

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.
