Alloy 22 may be used as the waste package outer container material for disposal of high-level waste at the potential repository at Yucca Mountain, Nevada. Crevice corrosion is one of the corrosion processes that may affect the performance of the waste package outer container. The relative susceptibility of Alloy 22 to crevice corrosion is evaluated through the measurement of crevice corrosion repassivation potential (Ercrev) using electrochemical test methods. The main purpose of the work described in this paper is to verify some Ercrev values reported in the literature and investigate the effects of different electrochemical test methods on the measurement of Ercrev. This work also provides risk insights and reduces the measurement uncertainties associated with evaluating the effects of the fabrication process on crevice corrosion susceptibility.
