Abstract

The corrosion reactions of two proposed canister materials, pure copper and Ti-Grade 2 alloy, have been investigated in MCC-1P suggested simulated brine solutions. Test temperatures were 90°C, 150°C and 250°C. The corrosion experiments were conducted under the test procedures of ASTM G1-81, but some modifications of postcleaning procedure were proposed in this study. Experimental results showed that Ti-Grade 2, with an extremely low long-term uniform corrosion rate of 0.1 μm·y-1 proved to be an excellent corrosion-resistance ability. The corrosive behaviors of Ti-Grade 2 can be correlated with semi-logarithmic rate functions. Copper, on the other hand, appeared unfeasible under brine circumstances owing to its higher uniform corrosion rate. Its related corrosive behavior could be described by linear equations. Temperature effects on corrosive behavior correlated efficiently according to the Arrhenius functions, indicating a negative influence on corrosion rates.
