Abstract: ITER diagnostic port plugs perform many functions including structural support of diagnostic systems under high
electromagnetic loads while allowing for diagnostic access to plasma. The design of diagnotic equatorial
port plugs (EPP) are largely driven by electromagnetic loads and associate response of EPP
structure during plasma disruptions and VDEs. This paper summarizes results of
transient electromagnetic analysis using Opera 3d in support of the design activities
for ITER diagnostic EPP. A complete distribution of disruption loads on the Diagnostic First Walls
(DFWs). Diagnostic Shield Modules (DSMs) and the EPP structure, as well as impact on the system
design integration due to electrical contact among various EPP structural components are discussed.
