Abstract

The objective of this research is the FM assessment of neutron damage to AISI 316 H steel commonly used in LMFBR's permanent primary circuit components. The material FM characteristics studied are the crack initiation toughness and the crack growth resistance curves. The AISI 316 H stainless steel has been considered in the base condition, the welded deposit and the HAZ material. The specimens tested are 3PB bars. The results that will be presented cover the 0; 0.1 dpa and 0.3 dpa fluences at 350 degrees C and 550 degrees C. The crack growth resistance curves were obtained following the dimensional analysis approach together with the deformation theory of plasticity concepts. This method, using key curves, the determination of which will be illustrated, has effectively shown trends in the above-mentioned fracture mechanics characteristics of the irradiated AISI 316 H steel.
