定期拆卸喷气部件以进行表面分析，以评估材料迁移和燃料保留情况。本文描述了与处理喷射部件有关的问题和准备用于分析的样品的程序；特别是介绍了一种新开发的切割铍砖的程序。还考虑到了在计划于2017年进行TT和DT操作(DTE2)之后，由于氚库存增加和14 MeV中子材料激活而可能造成的危险。得出了处理DTE2后喷气式飞机部件的可行性结论。
JET components are removed periodically for surface analysis to assess material migration and fuel retention. This paper describes issues related to handling JET components and procedures for preparing samples for analysis; in particular a newly developed procedure for cutting beryllium tiles is presented. Consideration is also given to the hazards likely due to increased tritium inventory and material activation from 14 MeV neutrons following the planned TT and DT operations (DTE2) in 2017. Conclusions are drawn as to the feasibility of handling components from JET post DTE2.
