In recent years, nuclear industry has realized the potential of deploying additive manufacturing (AM) technology to fabricate reactor internal components due to its capability to produce complex near net shape geometries with minimum tooling requirement. For current reactor service and future reactor design/fabrication, additive manufacturing technology can significantly reduce the fabrication cost and time to market while improve the component performance. In this study, austenitic stainless steel fabricated by Direct Metal Laser Melting (DMLM) is evaluated for light water reactor applications. The corrosion fatigue and stress corrosion cracking of the AM stainless steel in boiling water reactor environment are studied under different post treatment conditions. The effects of crack propagation orientation, K level, and corrosion potential on SCC crack growth rate are studied in detail. The potential risk from the new process and EAC mechanism of this grade of material are also discussed in the talk.
