国际原子能机构于2010年11月发布了修订后的“核保障测量不确定度国际目标值”(International Target Values 2010 for Measurement Uncertainties in Safeguarding Nuclear Materials),该报告提出了设施核材料衡算系统常用测量分析方法测量不确定度的目标值,为设施核材料衡算系统设计和闭合衡算评价提供了参考数据。国际目标值汇集了核设施U、Pu材料分析测量的主要方法以及常规不确定度参数,并分解为
In November 2010, the International Atomic Energy Agency released the revised International Target Values 2010 for Measurement Uncertainties in Safeguarding Nuclear Materials, which presented a proposal for a facility nuclear material accounting system The commonly used measurement and analysis method to measure the target value of uncertainty provides the reference data for the design of nuclear material accounting system of construction facilities and the assessment of closure. The international target value brings together the main methods of nuclear facility U, Pu material analysis and measurement as well as the conventional uncertainty parameters and is decomposed into
