    This study examined the effect of specimen size on J-R curves for reactor pressure vessel (RPV) steels. Overall comparisons for monolithic materials (base plate and forging) indicated that no significant size effect is apparent, using standard formulations for the J-integral within commonly accepted validity bounds. However, materials that are composite in nature, such as weld materials, or exhibit macro-scale inhomogeneities gave significant differences in JR curve trends for different sizes of specimens.
