Assessment of the fracture margin of irradiated Light Water Reactor (LWR) austenitic stainless steel components requires knowledge of the fracture toughness as a function of neutron fluence. Since toughness strongly depends on irradiation conditions, particularly flux spectrum and temperature, it is important that fracture toughness test specimens be obtained from samples that have experienced actual LWR irradiation. This paper presents the results of an investigation of the fracture toughness of irradiated Type 304 stainless steel and evaluates the applicability of the relatively new short-rod fracture toughness test to remote testing. The test samples were obtained from instrumentation removed from an operating LWR. The accumulated fluence was
