Abstract

Abstract:

Four methods of TBM FW fabrication are introduced. A 304 stainless steel FW mockup was fabricated with Machining-EBW-Bending method. The fabricated FW mockup was cut along one of square channels and measured. The minimum area of the channel at the bending place was 85% of original. The thickness of the wall on the outside of the channel at the bending place was apparently reduced, but could be controlled by machining. To demonstrate the availability of this processing technique, the RAFM which actually used on FW should be used in future work.

Key words: TBM, FW, Welding, Bending

摘要：

介绍了ITER实验包层模块(TBM)第一壁(FW)的四种加工方式，并且采用其中一种铣槽—电子束焊接—折弯法，用304不锈钢加工了一个FW验证件。对制成的FW样件沿流道切割开，测得弯曲处最小流道面积为弯曲前的85%，弯曲处流道外侧壁厚的减薄较明显，但可以通过机械加工的方法来控制。为了进一步证实这种加工方式的可行性，下一步须使用FW实际使用的低活化铁素体马氏体钢(RAFM)来研究此方法。
