Description
Following the results obtained in CHINON B1 comparing deposited activity observed on different surface finishes EDF decided to electropolish steam generator channel heads (S.G.C.H.) in order to reduce operator dose during plant maintenance. The qualification tests were performed on steam generator materials (Inconel 600 and S.S. 308 L) with the full on site operational equipment (i.e. a sealed sucker). In 1988 the 4 SGCH of NOGENT 2 were electropolished. In 1990 we observed a dose rate reduction of 45% at NOGENT 2 compared to NOGENT 1. Other French experience is electropolishing of 27 S.G.C.H., since 1988. (author)
