Measurement of Long-Lived Radionuclides in Fusion Materials

Source

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).
