Abstract

Abstract:

The selection of the rupture disc in vacuum vessel pressure suppression system (VVPSS) of CFETR is carried out according to the relevant standards. The design and the calculation of the rupture disc are completed under the VVPSS working conditions, and the preliminary results show that the diameter of disc is 882mm and its thickness is 1mm. The structural analysis and the comparison of the various rupture discs are carried out with the finite element analysis software, the anti-arched rupture disc with toroidal seam is selected finally. The finally selected rupture disc is optimized to meet the design requirements.

Key words: Vacuum vessel pressure suppression system, Rupture disc, CFETR, Finite element analysis

摘要：

参照相关标准，对聚变装置真空室超压保护系统(VVPSS)中爆破片进行了选型。结合VVPSS的工作要求，完成了爆破片的设计计算，初步得到爆破片直径为882mm，厚度为1mm。利用有限元分析软件对多种型号爆破片进行结构分析比较，最终选用了反拱环向开缝型爆破片。对最终选定的爆破片进行优化设计，使其达到设计要求。
