The crack initiation can occurs in different conditions; also in
ultra-high purity water with hydroxyl anion content below 10 ppb,
in relatively high temperatures (>150 C)- such is the case for LWRs
(Ford and Andresen, 2002). In water environments, EAC of steels is
considered to occur when the crack growth rates are more than
three times those observed in air (Cattant et al., 2008). In dependence
of environment, EAC can be considered as stress corrosion
