Major interests of Materials & Chemistry center on the integrity of structural materials in Nuclear Power Plants and facilities.
By aging, all structural materials in NPPs suffer from various degradation phenomena such as corrosion and stress corrosion cracking in reactor coolant conditions and external conditions.
Since such material degradation could affect the safe operation of NPPs, it is very important to identify possible degradation mechanisms for components and structures, to investigate their kinetics, and to evaluate their consequences.
