Abstract
Nickel enriched in Ni-59 was extracted from the fragments of a fracture toughness specimen of Inconel ∗ ∗ Inconel is a registered trade mark of the International Nickel Company. 600 irradiated in the Engineering Test Reactor (ETR). The nickel contained 2.0% Ni-59. Three heats of austenitic steel doped with Ni-59 were prepared and inserted in the Materials Open Test Assembly (MOTA) of the Fast Flux Test Facility (FFTF). The experiment is single variable in helium effects because chemically identical alloys without Ni-59 are being irradiated side by side with the doped material. The doped alloys will produce 10–100 times more helium than the control alloys. The materials include ternary and quaternary alloys in the form of transmission electron microscope (TEM) discs and miniature tensile specimens. The helium-to-dpa (displacements per atom) ratio will be in the range 5 to 35 and will be nearly constant throughout the irradiation. The exposures will range from 0.25 to 50 dpa over the duration of the experiment. The irradiation temperatures cover the range of 360–600°C.
