With implantation of next generation reactor designs and the operation of some US light water reactors extending beyond 60 years, the integrity of materials used in permanent structures after exposure to high fluences need to be assessed. In response to this challenge, this work focuses on neutron irradiated steels that were irradiated to high fluences/displacement damage in pressurized water reactor and advanced test reactor. This contribution will cover both microstructure and mechanical properties of neutron irradiated steels. The microstructure of the specimens was characterized in transmission electron microscope (TEM) and obtained data includes information on dislocation loops, precipitates, and voids. In addition to TEM-based characterization, the mechanical properties of these neutron irradiated steels were accessed using micro-tensile tests using a PI88 PicoIndenter.
