Corrosion is one of the unavoidable problems in nuclear reactor cooling systems that use water as a medium. secondary systemThe Reaktor Serba Guna–G.A. Siwabessy (RSG-GAS) an open recirculation system uses carbon steel pipes for delivery. Due to obvious system, components interact with oxygen air, resulting corrosion. control RSG-GAS has been accomplished through continuous injection zinc phosphate (ZnPO4) inorganic inhibitors, but these inhibitors can contribute environmental pollution and health issues. To resolve concerns, environmentally-friendly corrosion such carboxymethyl chitosan have used. CMC (carboxymethyl chitosan) widely used because it more amphiprotic than other derivatives. Because number functional groups chitosan, effective inhibitor. The inhibition test by on was performed using weight-loss method this study variations 0, 1, 3 g CMC. material's composition 0.23% C, 0.17% Si, 0.008% P, 0.004% S, 0.012% Cr, 0.037% Mn. According study, rate generated at 8.237, 5,645, 5,113 mpy, respectively. data, addition reduce weight loss due contains many are adsorbed surface half-full d Fe orbitals.
