裂变气体核素γ射线效率刻度中的自吸收校正
蒙特卡罗方法 HPGe探测器 探测效率 自吸收校正
2011/8/16
针对裂变气体核素HPGe探测器效率刻度中的自吸收校正问题,本工作详细描述了源盒、探测器和源物质等计算中需要的参数,按照实际的几何布局建立了HPGe探测器效率的蒙特卡罗计算模型,并编制了相应计算程序。计算模型可靠性得到实验数据的验证,用该模型计算了裂变气体核素在不同源介质下的探测效率,得到了相应的自吸收校正因子。

Reliability Assessment of 2400 MWth Gas-Cooled Fast Reactor Natural Circulation Decay Heat Removal in Pressurized Situations
2400 MWth Gas-Cooled Fast Reactor Natural Circulation
2009/9/3
As the 2400 MWth gas-cooled fast reactor concept makes use of passive safety features in combination with active safety systems, the question of natural circulation decay heat removal (NCDHR) re...
Buckling of Imperfect Thin Cylindrical Shell under Lateral Pressure
Lateral Pressure Cylindrical Shell
2009/9/3
The strength of thin shells, under external pressure, is highly dependent by the nature of imperfection. This paper investigates buckling behaviour of imperfect thin cylindrical shells with analytical...
