聚变反应堆焊缝超声检测标准比较

Comparison of ultrasonic testing standards for welding seams in fusion reactors

摘要: ITER（国际热核聚变实验堆）及CFETR（中国聚变工程实验堆）大型聚变装置的役前及在役无损检测分别参照标准RCC-MR-2007第3部分及标准NB/T 47013-2015执行。从适用范围、表面准备、探头参数规定、标准试块和对比试块、扫查方式、缺陷表征和验收等几个方面，将RCC-MR-2007中对接接头焊缝常规超声检测与NB/T 47013-2015中焊缝超声检测标准的相关内容进行对比，使设计人员更加深入地理解相应标准，并为设计优化提供参考。

Abstract: The pre-service and in-service NDT of ITER and CFETR fusion devices shall be performed in according with RCC-MR-2007 SECTION 3 and NB/T 47013-2015, respectively. In this paper, conventional ultrasonic testing of butt joint welds in RCC-MR-2007 and NB/T 47013-2015 is compared from the aspects of applicable scope, surface preparation, probe parameter, calibration and reference block, scanning method, characterization of indications, so as to provide reference for designers to understand the corresponding standards and design optimization.
