摘要

本文阐述了固体辐射损伤数学模型的物理基础。基于6种级联函数，考虑了缺陷产生的以下阶段:初级敲除原子、原子碰撞级联(损伤形成的动态阶段)。所述模型的软件实现包含在RTS&T代码中，该代码设计用于多粒子(200种粒子、共振和离子)在能量范围高达20 TeV的异质三维几何中辐射输运的统计建模。在低能区域，RTS&T传输模型基于直接使用以ENDF-6格式提交的评估核数据文件中包含的所有信息。报告将数值模拟结果与实验数据进行了比较。

MATHEMATICAL MODEL OF PRIMARY RADIATION DAMAGE TO THE BOROSILICATE GLASS INTENDED FOR IMMOBILIZATION OF RADIOACTIVE WASTE

The paper describes the physical basis of the mathematical model of radiation-ion damage in solid matter. The following stages of defect generation are considered: primary knocked out atoms, atomic collision cascades (dynamic stage of damage formation) based on 6 types of cascade functions. The software implementation of the described model is included in the RTS&T code designed for statistical modeling of multi-particle (200 types of particles, resonances and ions) radiation transport in heterogeneous 3D geometries in the energy range up to 20 TeV. In the region of low energies, the RTS&T transfer model is based on direct use of all the information contained in the evaluated nuclear data files submitted in the ENDF-6 format. The report compares the results of numerical modeling with experimental data.
