Nitrite effects on copper corrosion in nitric acid solutions
Source abstract
Abstract
Abstract The proposed long term management plan for Canadian spent nuclear fuel is to seal it in copper-coated steel containers and bury it in a deep geologic repository. During the early period after emplacement, the container could be exposed to a humid, aerated, and irradiated environment containing nitric acid. The corrosion of copper was studied in aerated and de-aerated nitrate solutions with emphasis on the influence of nitrite produced by nitrate reduction. Using various electrochemical and surface analytical techniques nitrite was shown to compete with nitrate for surface adsorption sites and, if present at sufficient concentrations, cause rapid corrosion of copper.
