Effect of Dissolved 90Sr and 137Cs in HCl Solutions on the Corrosion Potential of Type 316L Stainless Steel

In order to analyze the effect of beta particles in solution on the corrosion of Type 316L stainless steel, the effect of dissolved 90Sr on the corrosion potential was investigated. 90Sr standard solution and 137Cs standard solution were dropped into HCl while the corrosion potential was measured in HCl. As a result, the potential increase in the solution with 90Sr standard solution was larger than that in the solution with 137Cs standard solution. The results were verified by calculations, which show that the difference in the rate of formation of H2O2 in solution due to water radiolysis causes a difference in the change in potential in both solutions.
