Nanolayered materials show improved resistance to irradiation compared to bulk counterparts due to presence of a high volume ratio of interfaces that provide recombination sites for point defects. In addition, the interfaces can also trap He in the form of small bubbles/clusters retarding the formation of cavities. However, almost all of the work was carried out using accelerator based techniques. To assess the performance of these alloys in a reactor for the first time, nanolayered free standing Cu/Nb films with 5, 20 and 40 nm layer thickness were irradiated in ATR. The irradiation temperature ranges 275-750C with a total dose of ~6 dpa. Furthermore, the Cu/Nb films were also Ni coated to implant He during irradiation. In this talk, the results of neutron irradiations on microstructure from selected dose and temperatures will be discussed.
