Environmental cracking austenitic stainless steel under neutron irradiation affects the structural integrity of nuclear reactor systems. Over the past 40 years, significant progress has been made regarding the fundamental understandings of these phenomena in high temperature water systems. Strategies, including water chemistry control, weld residual stress management, steel sensitization management, high Cr alloy design, etc., have been implemented. This talk provides an overview of history of environmental cracking in nuclear systems and highlights our new approach to understand this phenomena and develop radiation and cracking resistant stainless steel for nuclear environments.
