Abstract:

The shield block (SB) full scale prototype (FSP) should be designed based on the current design pattern, fulfill its physical function, and meet the design requirements of blanket interface. Moreover, the R&D results of the key manufacturing technologies should be fully considered in the SB FSP design, particularly the technology of deep drilling, TIG welding, NDT and etc. These R&D results provide strong support for the design. The manufacturing of the SB FSP is the necessity for the procurement agreement (PA) signing, and it also provides a sound basis for PA accomplishment.

Key words: ITER, Blanket, Shield block, Design, Prototype

摘要：

ITER 包层屏蔽块全尺寸原型件应基于当前的设计方案，满足其物理功能，并符合包层界面的设计要求。另外，在屏蔽块全尺寸原型件的设计中，还要充分考虑关键制造技术的研发结果，例如深孔钻、TIG 焊接、NDT 检测等技术，这些关键制造技术的研发结果，为设计提供了技术保障。该全尺寸原型件的顺利完成并通过ITER 相应认证程序，是中方签署采购的必由环节，也为今后完成采购包奠定了基础。
