对设计用于成像64m处核电站内部结构的Muon射线照相系统的性能进行了评估。我们得出结论，在测量期间，压力容器中没有燃料，并对放置在储存池中的燃料材料进行了分析。获得的数据还表明，该系统对反应井和干燥器-分离器池中的水位变化很敏感。预计该系统可以很容易地重建一个200万立方米的燃料物体。通过操作多个系统，通常是四个相同的系统，从不同的方向同时观察反应堆，也应该可以在几个月内实现对1米立方体物体的探测。
The performance of a muon radiography system designed to image the inner structure of a nuclear plant located at a distance of 64m is evaluated. We conclude that there is an absence of fuel in the pressure vessel during the measurement period and profile the fuel material placed in the storage pool. The obtained data also demonstrate the sensitivity of the system to water-level changes in the reactor well and the dryer-separator pool. It is expected that the system could easily reconstruct a 2m cubic fuel object. By operating multiple systems, typically four identical systems, viewing the reactor from different directions simultaneously, detection of a 1m cubic object should also be achievable within a period of a few months.
