Abstract

Nuclear transmutation emerges as a promising approach for reprocessing high-level waste, specifically treating long-lived nuclides like 93Zr from spent fuel. It is essential to accumulate reaction data for these nuclei to advance this prominent treatment and to build a comprehensive understanding of reaction mechanisms. In this study, the residual production cross sections resulting from proton-induced reactions on 93Zr were measured at 27 MeV/nucleon in inverse kinematics. At the RI Beam Factory (RIBF) the OEDO beamline was used to deduce production cross sections for isotopes, 91 − 93Nb, 91, 92Zr, and 88, 89Y. Comparing the results from this study and prior research with calculated excitation functions, a moderate agreement is found with theoretical predictions derived from TALYS and CCONE. The measured cross sections offer valuable insights for future considerations in nuclear-waste treatment facilities. This is particularly relevant for facilities exploring innovative methods, such as accelerator-driven systems.

在 27 MeV/核子频率下 93Zr + p 产生残余核素的生成截面

核嬗变是对高放射性废物进行后处理，特别是处理乏燃料中 93Zr 等长效核素的一种很有前途的方法。积累这些核素的反应数据对于推进这一重要处理方法和全面了解反应机制至关重要。在这项研究中，以 27 MeV/核子的反向运动学测量了 93Zr 上质子诱导反应产生的残余生成截面。在里约热内卢光束工厂（RIBF），利用 OEDO 光束线推导出了 91 - 93Nb、91、92Zr 和 88、89Y 等同位素的产生截面。将这项研究的结果与之前通过计算激发函数得出的研究结果进行比较，发现两者与 TALYS 和 CCONE 得出的理论预测结果基本一致。测量的横截面为核废料处理设施的未来考虑提供了宝贵的见解。这对于探索创新方法（如加速器驱动系统）的设施尤为重要。
