In water-cooled reactors measures to minimize the radiation fields due to the transport and deposition of {sup 60}Co are important to ensure low occupational doses of radiation. For example, it is now accepted practice to add zinc to boiling water reactor coolant to minimize {sup 60}Co transport and pickup by surfaces. This paper describes a study of the kinetics of {sup 60}Co deposition on Type 316 stainless steel in neutral, partially deoxygenated water at 563 K and 10.2 MPa with and without zinc traced with {sup 65}Zn. The effect of zinc addition on the corrosion rate of preoxidized stainless steel was also studied using relatively high concentrations of additive. General observations and a mathematical model of the corrosion rate provide insights into the possible mechanisms involved.
