Abstract

Neutron production cross sections are reported for reactions leading to long-lived isotopes in fusion reactor materials. Pure elements and separated isotopes were irradiated with 14.6–14.8 MeV neutron fluences up to 1018 n/cm2. Undesired activities were chemically separated and the long-lived activities were measured using both liquid scintillation and x-ray spectrometry. Results are presented for the reactions56Fe(n,2n)55Fe(2.73 y),64Ni(n,2n)63Ni(100 y),63Cu(n,p)63Ni, and60Ni(n,2n)59Ni(76,000 y).
