在本文中，宇宙射线μ子射线照相术已被用来识别密封干燥储存桶内是否存在乏核燃料束。干燥储存桶用于容纳高放射性内容物辐射的大量屏蔽阻碍了典型的成像方法，但宇宙射线μ介子的穿透性使它们可以用作有效的射线照相探针。该技术能够成功识别密封的 Westinghouse MC-10 桶内丢失的燃料束。这种燃料桶核查方法可能对国际核保障视察员有用。最后，μ子射线照相术可能会发现其他安全和保障或保障应用，例如军备控制验证。
In this paper, cosmic ray muon radiography has been used to identify the absence of spent nuclear fuel bundles inside a sealed dry storage cask. The large amounts of shielding that dry storage casks use to contain radiation from the highly radioactive contents impedes typical imaging methods, but the penetrating nature of cosmic ray muons allows them to be used as an effective radiographic probe. This technique was able to successfully identify missing fuel bundles inside a sealed Westinghouse MC-10 cask. This method of fuel cask verification may prove useful for international nuclear safeguards inspectors. Finally, muon radiography may find other safety and security or safeguards applications, such as arms control verification.
