 This study evaluates the corrosion behavior of an aluminum alloy used in the isphan miniature neutron source reactor's dry channel component which has been exposed to radiation for 12 years in a water environment within the reactor pool. The study uses various tests such as mechanical strengths XRD, TEM, SEMEDS, and Potentiodynamic Polarization, PDP, to determine the effect of radiation on the corrosion of the LT21 aluminum alloy used in the DC. The neutron and gamma dose distribution along the height of the DC is calculated to determine the correlation between the dose distribution and observed corrosion, and the study finds that the corrosion mechanisms are complex and result from the simultaneous presence of the DC in the pool water and radiation from the reactor core.
