cosSOURCE软件与ORIGEN程序燃耗计算功能对比分析
|
Abstract:
堆芯积存量是核电厂设计中最基础的辐射源之一，它在确保反应堆安全运行、预防潜在风险、确保辐射防护和废物管理的合规性等多个方面都非常关键。本文以第三代压水堆的工程例题为基准，针对核电厂设计中常被关注的几组核素，将国家电投集团科学技术研究院有限公司研发的cosSOURCE软件的中子活化及燃耗分析模块与工程上常用的ORIGEN程序计算结果进行了对比分析，对比结果显示两者计算结果符合性较好。
Core inventory is one of the most basic source terms in the design of nuclear power plants. It is crucial in ensuring the safe operation of a reactor, preventing potential risks, and ensuring compliance with radiation protection and waste management. This article uses an engineering benchmark case of a third-generation pressurized water reactor to compare the results from the neutron activation and burnup analysis module in cosSOURCE software, developed by the State Power Investment Corporation Research Institute, with the results from commonly used ORIGEN code. The comparison results show that the calculation results of both are generally consistent.
