Radiation-induced electrolytic phenomena with differential radiation cell in water-cooled nuclear reactors

摘要

Background: The ''differential radiation cell (DRC)" is an adaptation of ''differential aeration cell" which is widely applied in conventional corrosion studies. However this mode of corrosion has been dismissed in the nuclear community considering that the transport of ions with flow is unlikely due to the high purity of reactor water. The author found that the analogous mechanism should be occurring in reactor water with radiation differences. This phenomenon should be inducing a severe interaction between structural materials and their environments found in light water reactors through ''radiation-induced electrolytic (RIE)" corrosion.
