Corrosion behaviour of copper alloys in the WWER-440 secondary coolant circuit
Description
Brass did not prove useful as the tubing material in low-pressure preheaters. Tubing lifetime is ≤ 16 years for the higher stages of heating. Another drawback is release of copper into the feedwater. Consequently, brass tube low-pressure preheaters are an essential source of steam generator fouling. Moreover, the dissolved copper supports local corrosion of the generator tubes. Brass is proposed to be substituted by austenitic CrNi steel as the tubing material of low-pressure preheaters. (author)
