大型先进压水堆核电站关键设计软件自主化与COSINE 软件包研发

摘要

本文介绍了国内第一套完全具有自主知识产权的核电厂工程设计与安全分析软件“COSINE”软件包的研发实施情况，对COSINE的技术目标、技术路线、研发进展和取得的技术成果等方面进行了阐述。本文给出了核电软件的评价模型定义和开发方法，并对COSINE软件包在开发过程中不同阶段的技术成熟度和应遵循的研发4个阶段进行了解释。COSINE已具备压水堆核电站堆芯物理—热工水力及系统安全分析的核心功能，取得的研发成果将在具备自主知识产权的CAP1400机组或其他压水堆机组上推广应用。%This paper introduces the development of“COSINE”—the first nuclear power key design software owning independent intellectual property right in China, from the aspects of technical goal, technical route, development progress and achievements. In this paper, we also illustrate how to define and develop evaluation model, and introduce maturity of technology in all development phase of COSINE. COSINE, with key function of reactor core physics analysis, thermal-hydraulics analysis and system safety analysis, will be popularized and applied in CAP1400 and other NPP units with independent intellectual property right.
