| Description |
Radiation field reduction in the primary heat transport (PHT) system of water-cooled reactors can be
achieved by ‘dilute chemical decontamination (DCD)’ process. The corrosion behaviour of carbon steel has
been studied in the absence and presence of different concentrations of cinnamaldehyde in 4.76mML−1 of
citric acid for different immersion times (6 h and 24 h) at 30 ◦C using weight loss, potentiodynamic polarization
and impedance measurements. Cinnamaldehyde has given an inhibition efficiency of about 90%
at 15.15mML−1 and inhibition efficiency is decreased to 82% when duration of immersion increased from
6 h to 24 h. Electrochemical studies followthe same trend as those observed inweight loss measurements.
The formation of the adsorbed inhibitor film on the carbon steel was further confirmed by FTIR studies.
