The Structure Analysis of the EAST Updated Divertor

摘要

After EAST_2012 campaign, the updated divertor (upper part) has been designed and installed in EAST. The updated upper divertor is designed as cassette structure like ITER divertor. The structure analysis has been carried out for divertor cassette design in the worst case loads of disruption with the maximum 1 MA of the plasmas current. A series of finite elements analysis indicates that the divertor cassette is able to withstand the electromagnetic (EM) load resulting from halo current, combined with EM load caused by eddy current, gravity and pressure of cooling water.
