Vf. Baston et al., DECONTAMINATION FLANGE FILM CHARACTERIZATION FOR A BOILING WATER-REACTOR UNDER HYDROGEN WATER CHEMISTRY, Nuclear technology, 114(3), 1996, pp. 337-350
Stainless steel artifacts removed from a boiling water reactor class 4
plant that operated under hydrogen wafer chemistry and experienced a
difficult decontamination were submitted for oxide film characterizati
on. The results reported for the corrosion film composition and struct
ure are consistent with existing theoretical concepts for stainless st
eel corrosion, spinel structure site preferences (octahedral or tetrah
edral) for transition metal ions, and potential-pH diagrams. The obser
ved zinc effects on film stability and lower cobalt incorporation are
also consistent with these theoretical concepts.
