宇宙线μ用于反应堆燃料元件成像的尝试性模拟研究

Simulation Study on Cosmic Ray μ Tomography for Reactor Fuel Elements

摘要: 建立了用于Monte-Carlo模拟的μ抽样模型。使用此模型，采用Geant4程序和Root软件，对核燃料元件的μ成像进行模拟研究。模拟成像结果显示，基于将多次库伦散射等效为单次散射的径迹重建方法，可实现核燃料元件的μ成像。

Abstract: A model of sampling on the cosmic ray μ was developed. The preliminary simulation study on μ tomography for reactor fuel elements was finished using Geant4 program and Root software. The simulated results show that it is feasible to detect the reactor fuel elements using the point of closest approach algorithm based on the simplification of multiple Coulomb scattering.
