The present paper focuses on electromagnetic simulations of ECT for helical SG tubes and large SP models. Large scale 3D simulations are validated by comparison with experimental measurements conducted in a mock-up test in our laboratory. State of the art parallel numerical simulations using an electromagnetic code developed with a hybrid OpenMP-MPI approach for very large FEM models are conducted using up to 1024 CPUs in Fujitsu BX900 supercomputer. The availability of large models offers new insights into ECT for large structures in FBR, where electromagnetic interference can appear due to close proximity of multiple tubes.
