Investigation of the capsule detection method at the irradiation end of the ITER neutron activation system

Abstract

Due to the harsh radiation, thermal, and electromagnetic environment of the irradiation end of the ITER neutron activation system, which also forms a primary vacuum boundary and a nuclear safety confinement boundary simultaneously, installing a capsule detection sensor at this location, which is essential for reliable operation of the system is extremely challenging. Alternative capsule detection methods utilizing sensors located in more benign environments are investigated experimentally in this study. The experimental result suggests that a simultaneous measurement of the pressure and the acoustic/vibration wave will provide reliable information on the capsule arrival at the irradiation end.
