N2 - The microstructural evolution of neutron irradiated Nb-1Zr alloy at 693-1003 K to doses as high as 47.2 dpa has been investigated. At all irradiation conditions, strong void swelling resistance was found. In the cold-worked and aged specimens, voids of about 50 nm diameter were observed at lower temperature (693 K) and higher temperature ranges (918-1003 K), but not at intermediate temperature ranges (744-842 K). The void density increased with dose. The swelling behavior obtained by density measurements was revealed to be rather complex, depending on irradiation temperature and dose. The complex role of starting condition on both microstructural evolution and density changes are presumably due to phase-related changes during irradiation.
