Abstract
Remote handling constitutes a critical technological facet in the domain of fusion reactors. However, exposure to γ rays inflicts irreversible deleterious effects on both electronic assemblies and structural materials. In the present investigation, we meticulously engineered an electro-hydraulic dual system tailored for remote handling applications within fusion reactors. Subsequently, the system was subjected to γ irradiation employing 60Co as the radioactive source. After exposure to a dose of 4 MGy, the electro-hydraulic dual joint system demonstrates sustained functional integrity. In contrast, isolated electric and hydraulic joints manifests minor oil seepage after exposure to a radiation dose of 5 MGy. Additionally, the effectiveness of the selected O-ring sealing material, ethylene propylene diene monomer (EPDM), exhibits a significant decrement upon irradiation to a dose of 1–3 MGy. The observed γ-radiation resilience is attributed to strategic material selection, specifically in the choice of O-ring, as well as metal reinforcement. The findings furnish valuable insights for the development of remote handling systems capable of operating under γ irradiation and strenuous mechanical conditions.
