A Review of Aluminum Corrosion in Tap Waters

Review of oxidation rates of DOE spent nuclear fuel : Part 1 : nuclear fuel.

“…The corrosion rate of aluminum alloys is known to be sensitive to water chemistry variations in conductivity, pH, and impurity levels. 97 , 98 , 99 Specifically, aluminum is susceptible to localized attack as pitting in water chemistries of high conductivity and impurities such as chlorine and copper. 97,98,99 The dependence of aluminum corrosion behavior on water chemistry has been observed in fuel storage basins across the DOE Complex at Hanford, Idaho National Engineering and Environmental Laboratory, Brookhaven National Laboratory, Oak Ridge National Laboratory and Savannah River Site.…”

Corrosion and protection of aluminum alloys in seawater

“…Susceptibility to pitting and crevice corrosion may increase with chloride content, temperature [1] and pressure [10,11]. Added presence of heavy metal ions and dissolved CO 2 is not beneficial, since unexpected negative synergy of these species, together with Cl -, dissolved oxygen and elevated temperature and pressure may cause high corrosion rates [12].…”

Impact of Aluminum on Anticipated Corrosion in a Flooded SNF Multi Canister Overpack (MCO)

“…oxygen concentration and the presence of copper. either as dissolved ions or coupled electrically [4][5][6][7][8][9]. Figure 4 shows a schematic polarization diagram for aluminum in air-saturated water at neutral (pH=7) conditions.…”
