Evaluation of electromagnetic loads on various design options of the ITER diagnostic upper port plug during plasma disruptions

An efficient modeling of fine air-gaps in tokamak in-vessel components for electromagnetic analyses

“…efficient routine to implement the ESM has been developed in APDL language carrying out these actions automatically. In this section, we briefly present a successful application of the ESM technique to the EM load analysis on ITER diagnostic upper port plug (DUPP) [12].…”

“…8, and we refer the reader to Ref. [12] for details of the DUPP structure and present design status.…”

“…Section 3 is devoted to the application of ESM to a practical EM load analysis on ITER components based on its complete geometrical structures. The ITER diagnostic upper port plug (DUPP) [12] and neighboring BM are modeled using ESM, and EM loads on DUPP is calculated during a plasma disruption in ITER. Benchmarking the results with those obtained from the other method shows that ESM yields accurate results saving computational resources and time as well.…”

Electromagnetic analysis of ITER generic equatorial port plug designs during three plasma current disruption cases

“…Different electromagnetic analyses over different parts of VV components were made in [4][5][6][7][8][9]. In this paper the three plasma disruption cases studied are: major disruption upwards linear decay in 36 ms (MD UP LIN36), vertical displacements events, upwards and downwards linear decay in 36 ms (VDE UP LIN36 and VDE DW LIN36).…”
