| Abstract: | Using the Gaussian mixture model of halo current peak distribution and the limit state equation of targets structure, the reliability of EAST upper divertor targets was studied with the Monte Carlo method. The results showed EAST upper divertor targets had extremely high reliability under halo currents, which provided references for the research on reliability of EAST upper divertor and CFETR. |
