At the end of the life of a nuclear power facility handling radioactive species there is the need to safely decommission. In most cases this will leave a vast quantity of steel that will be reused, recycled or disposed of. All scenarios may require the use of some decontamination process in order to reduce associated radioactivity. Through determining the mechanism of binding and speciation of contaminants the decontamination process can be developed as effectively as possible. The contamination of stainless steels by transuranic material in conditions replicating those found in a reprocessing plant will be presented. An understanding of contamination by radionuclides on both corroded and unaffected steel surfaces has been established. All samples in contact with contaminant containing solutions have shown uptake with dependence on acid molarity and surface morphology. Both solution and surface analysis has been used to show the uptake mechanism and kinetics of the process.
