摘要
核物质包装体是一种核废料存储和运输的专用设备,在放射性核物质存储和运输的过程中,安全问题尤为重要。因此核物质包装体不仅要具有屏蔽射线的作用,还需要能够吸收冲击能量、保持结构稳定性,避免结构变形、破损等由破坏形式引起的核辐射泄漏。根据相关规定和标准,运用ANSYS Workbench的Explicit dynamic模块,对核物质包装体的跌落过程进行了分析研究,结合数值模拟结果分析了核物质包装体的应力以及应变,并采用合适的评价准则对结果进行评价,验证了结构和结构强度满足设计需求。
Nuclear material packaging is a kind of special equipment for nuclear waste storage and transportation. In the process of storing and transporting radioactive nuclear material,the safety problem is very important.Therefore,the packaging material of nuclear matter not only has the function of shielding rays,but also can absorb the impact energy,maintain structural stability,avoid structural deformation,damage and other forms of damage caused radiation leaks. According to the relevant rules and standards,ANSYS Workbench＇s Explicit dynamic module was used to analyze the dropping process of the nuclear material package. The stress and strain of the nuclear material package were analyzed with the numerical simulation results,and the results were evaluated by appropriate evaluation criteria. The structural and structural strength were verified to meet the design requirements.
