核设施正常工况下气载放射性排出物环境影响评价软件的设计与开发

Design and Development of the Software for Environmental Impact Assessment on Radiological Gaseous Effluents under Normal Condition of Nuclear Facilities

根据评价核设施气态放射性物质的5种物理模型,采用模块化设计,清华大学核能技术设计研究院研制了环境评价软件NAREIA。与国内某核电厂环境评价报告计算结果的比较表明,NAREIA不仅能够满足三级模型逐级筛选的要求,而且比国内环境评价常用的模型均偏保守。

Based on the five strain physical schema and adopting block design, Nuclear Power Technology Design of Tsinghua University had developed the environmental assessment software. Compared with the calculated results from the environment assessment report for one nuclear power plant, NAREIA can not only satisfy the requirement of third class mode step sizing, but also is more conservative than the modes used in the environmental assessment in China.
