Intergranular attack of Alloy 600: simulation tests

Daret, J

In some steam generators, intergranular attack (IGA) has been detected on Alloy 600 tubes within or near the tubesheet crevice region. In order to reproduce IGA in an experimental device, refreshed autoclave simulation tests were performed with caustic pollution or river water in-leakage. During three runs of three tests each, chemical parameter and test procedures were adjusted to finally obtain a representative corrosion attack of tubing within the tubesheet crevice for the case of a caustic pollution. IGA was not detected for the river water in-leakage case.
