Regional Workshop on Stress Corrosion Cracking, 5–8 May 2008, Veracruz, Mexico
Within the framework of the Regional Technical Cooperation Project RLA4021, "Cracking and Structural Integrity of Components in Light Water Reactors", a Workshop on "Stress Corrosion Cracking (SCC)" was held from 5 to 8 May 2008 at Veracruz in Mexico.

The objective of the workshop was to exchange information on practices and R&D programmes performed by Member States relating to inter-granular stress corrosion cracking (IGSCC) including primary water stress corrosion cracking (PWSCC) and irradiated assisted stress corrosion cracking (IASCC) and on current practices to prevent, mitigate and repair SCC damages. Three experts from USA, France and Japan were invited for the workshop.
The workshop was co-organized with the IAEA and the counterparts in Mexico, i.e. National Institute of Nuclear (ININ) and Comision Federal De Electricidad (CFE). 44 participants attended the workshop. To accomplish the workshop objective, the three internal experts provided presentations on the following subjects:
- Basic mechanisms of IGSCC, PWSCC and IASCC;
- Methods how to measure and understand SCC issues;
- Operational experience;
- Inspection, assessment, prevention/mitigation, repair/replacement methods.
The workshop provided important information on SCC mechanisms, practical information and concrete examples of activities to cope with SCC issues.
