Previous studies have shown that the reactor effluent water radionuclides are produced mainly by the neutron activation of parent elements which have been adsorbed from process water onto the surface of the aluminum process tubes and fuel element jackets. Various methods have been studied, aimed at reducing effluent water radioactivity by minimizing this adsorption of parent materials. It was found that several types of protective films could be formed on aluminum surfaces which would greatly reduce the adsorption of parent materials. This was accomplished either by the continuous addition of chemical additives or selective corrosion inhibitors to the process water or by pretreatment of the aluminum surfaces with certain protective coatings. The adsorption inhibiting effects of process water additives, corrosion inhibitors, surface pretreatment processes and coatings on aluminum surfaces were studied. Two of the effluent water radionuclides of principal concern as As{sup 76} and P{sup 32} and the adsorption behavior from process water of their parent elements was normally used as an index of the effectiveness of a treatment. 5 refs.
