Resumen: The purpose of this study was to evaluate the possible degradation of the fracture toughness parameters in PWR service conditions by various factors such as loading rate and pressurized hot water environment. For that, tests on cr specimens with sustained load and low loading rates were made on a SA 508Cl3 steel with high sulfur content, in the aim to have a maximum of suceptibility. The results show that the usual J-R curve determinations in air at higher loading rateare applicable to the crack initiation and propagation in service conditions.
