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.
Most of the 18 chapters focus on stress-corrosion cracking
in a specific class of materials with the closing chapters more generally discussing welds in boiling water reactor systems, crack evaluation methods, and failure analysis.

In particular Stress-Corrosion Cracking
behaviour of pre-cracked samples shall be investigated using the unique test methodology and test frames/cells developed by ESA.
With nickel content below 1 per cent and Brinell hardness less than 200, this welding wire meets the requirements for applications where resistance to stress-corrosion cracking
36 Material selection for controlling stress-corrosion cracking
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.
This activity also contributed to the development of the direct-assessment technologies, which now are codified by NACE for internal and external corrosion, and for stress-corrosion cracking
(SCC) is a fracture phenomenon caused by the combined factors of tensile stress, a susceptible alloy, and a corrosive environment.
I should say at this point that I am a British corrosion specialist and that I have been interested in stress-corrosion cracking
for around 30 years.
