Abstract

This report presents an experimental result on quenching which affected by the Radiation Induced Surface Activation. Increasing of quenching velocity requires that the cooling liquid can contact the heated surface, or a high wettability of the surface when quenching initiates. From this point of view, an experimental study to investigate the relationship between surface wettability and quenching was performed by use of an oxide semiconductor-coated material after γ-ray irradiation. The results showed that highly surface wettability or highly hydrophilic condition of a simulated fuel rod made of SUS was achieved, and the quenching velocities were increased up to 15 % after 300 kGy 60Co γ-ray irradiation.
