ARCON96程序理论模型分析

Analysis of Theoretical Model of ARCON96

大气弥散因子是评价核电厂控制室可居留性的重要参数,美国核管理委员会采用ARCON96程序评估该参数。对ARCON96程序的基本原理及主要理论模型进行分析,并以安全壳表面释放情况为例,对程序中的面源释放扩散模型开展敏感性分析。为ARCON96程序的科学使用提供建议,保障计算的合理性。

The relative concentrations are major parameters for control room habitability assessments. ARCON96 computer code is developed for U.S. Nuclear Regulatory Commission Office of Nuclear Reactor Regulation for control room habitability assessments. The fundamental and the main theoretical models are analyzed. As a building surface release modeling, a sensitivity analysis on relative concentrations of a nuclear power plant containment radiological release is carried out. Some suggestions which would make the calculation more scientific are provided.
