Non-destructive inspection of iter pf jacket welds

Research output: Contribution to journalArticlepeer-review


The magnet system for ITER consists of 18 toroidal field (TF) coils, a central solenoid (CS), 6 poloidal field (PF) coils and 18 correction coils (CC). The PF coils are complex in design with a geometry jacket so-called "round-in-square". R&D studies have been developed to evaluate the suitability of several non-destructive testing methods to be implemented on this jacket during the manufacturing stage as a quality assurance method. Until now none of the techniques applied had a 100 % capability of detection. This paper presents the results of a study where three radiographic techniques were tested on samples of the jacket and these were: Industrial Radiography, Computed Radiography and Computed Tomography. The combination of the different radiographic techniques proved to be efficient as no other technique had been before.
