Abstract

In order to increase safety, nuclear component of the reactor have got good performance on normal operational conditions. One of nuclear component of the reactor is lining tank reactor. In this study, the aging component reactor of Aluminum alloy Al6061 as lining tank reactor Triga 2000 in demin water has been evaluation by using electrochemical methods. The electrochemical testing were performed in demin water with and without the addition NaCl as contaminant at ambient temperature. The electrochemical technique used in this study were open circuit potential (OCP), Tafel polarization and electrochemical impedance spectroscopy (EIS). The results of open circuit potential tests showed that the corrosion potential (Ecorr) values of Al6061 T alloy are slightly different between in demin water with and without the addition NaCl. The corrosion potential Al6061 T alloy are higher in demin water without NaCl compare with NaCl addition. The are show that the interaction between demin water and the aluminum alloy have no significant effect on to its corrosion behavior. However, Tafel polarisation of aluminum alloy Al6061 T alloy in demin water with the absence of NaCl showed the lowest corrosion than aluminum alloy at condition in demin water with NaCl. Eis study shows that aluminum alloy Al6061 T alloy in demin water with the absence of NaCl showed the higher impedance than aluminum alloy in demin water with NaCl. The higher impedance indicated that the passive film of Al2O3 formed on the surface of aluminum alloy. In terms of corrosion rate values, aluminum alloy Al6061T showed the best corrosion resistance in demin water without NaCl compare Al 6061 T in demin water with NaCl.
