    Abstract

    Neutron cross section measurements are reported for the production of long-lived radionuclides in fusion reactor materials. Samples were irradiated at 14.5 to 14.8 MeV at the RTNSII facility. Long-lived reaction products were detected using gamma and X-ray spectroscopy, liquid scintillation spectrometry, and accelerator mass spectrometry. Radio-chemical separations were performed for many samples prior to analysis. Results are summarized for reactions leading to 26A1 (720 000 y), 53Mn (3 700 000 y), 55Fe (2.73 y), 63Ni (100y), 59Ni (76 000 y), 91Nb (700 y), and 94Nb (20 300 y).
