Stress corrosion cracking, oxidation and high temperature aqueous corrosion are
life limiting factors in many nuclear process plant components. An Imaging
Autoclave has been developed to study these processes, in-situ. The system
combines refreshed-loop high temperature and pressure aqueous testing facilities
under dynamic loading, with the optical techniques of Digital Image Correlation
and Raman Spectroscopy. This paper reports an in-situ study of stress corrosion
crack nucleation and growth in Stainless Steel under simulated BWR
environments, using digital image correlation. This allows crack opening
displacements to be measured that are below normal optical resolution. The aim
is to measure crack propagation rates and determine nucleation sites.
