Abstract

In this study, an attempt has been made to investigate the ²³⁵U enrichment percentage in uranium compounds using the PIGE method with 25 MeV proton energy and to calculate the characteristic gamma energy of ²³⁵U. The results indicate that the characteristic gamma energy of 2.2 MeV corresponds to ²³⁵U in the uranium compound, where no gamma line from ²³⁸U is observed at this energy. By altering the percentage of ²³⁵U enrichment in the compound, the response of the CsI(Tl) detector to the 2.2 MeV gamma is formulated as a function of different enrichment percentages, utilizing the results obtained from MCNPX simulations. Furthermore, by examining various nuclear processes resulting from the interaction of protons with ²³⁵U and ²³⁸U, the reason for the gamma radiation at 2.2 MeV for ²³⁵U is also elucidated.

用高能质子PIGE方法计算235U富集的可行性

本研究尝试用质子能量为25 MeV的PIGE方法研究铀化合物中235U的富集百分率，并计算了235U的特征γ能。结果表明，2.2 MeV的特征γ能量对应于铀化合物中的235U，在该能量处没有观察到238U的γ谱线。通过改变化合物中235U的富集百分比，利用MCNPX模拟得到的结果，将CsI（Tl）探测器对2.2 MeV伽马射线的响应表示为不同富集百分比的函数。此外，通过研究质子与235U和238U相互作用所产生的各种核过程，还阐明了235U产生2.2 MeV伽马辐射的原因。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
