The laboratory-scale erosion-corrosion testing facility at BATAN's Center for Radioisotope and Radiopharmaceutical Technology (PTRR) in Serpong was employed to simulate flow-induced corrosion of iron surfaces. Surface loss rates were measured by a nuclear technique called thin layer activation (TLA) analysis. A 10-MeV proton beam generated from typical CS-30 cyclotron used produce 56Co radionuclide layers on surfaces via 56Fe(p,n)56Co reaction. labeled specimens then exposed circulating seawater simulated test facility. experimental results indicated that the TLA able measure very low erosion rate 0.91±0.3 µm/hr. There no significant difference surface between remaining activity method concentration method. lower than same material HCl solution observed earlier studies.
