Selection and calculation of rupture discs in vacuum chamber overpressure protection system of China Fusion Engineering Experimental Reactor

According to the relevant standards, the bursting discs in the vacuum chamber overpressure protection system (VVPSS) of the fusion device were selected. In combination with the working requirements of VVPSS, the design and calculation of bursting discs were completed, and it was preliminarily obtained that the diameter of bursting discs was 882mm and the thickness was 1mm. The structure of various types of bursting discs is analyzed and compared by using the finite element analysis software.
