The results of the researches [10, 11] showed that relatively small changes in the tensile stress and concentration of the corrosive component lead to a significant change in the time of stress-corrosion cracking of the heat exchanging pipes of steam generators of NPP with VVER, which explains the possibility of cracking of individual heat exchanging pipes and the normal operation of other heat exchanging pipes in one steam generator at the same time.
Corrosion of ENIG proceeded by stress-corrosion cracking of the nickel phosphorous plating, which was followed by pitting/crevice corrosion of the underlying copper pad in the vicinity of compromised NiP regions.

In recent years, many nuclear power plant operators in Japan, the U.S., and some European countries have begun to replace steam generators, reactor vessel heads, pressurizers, and other related components to reduce the risks associated with stress-corrosion cracking (SCC) of aging materials, and thereby enhance plant reliability and operational life.
