Abstract
Lithium oxide (Li 2O) is a candidate material for solid breeder blankets in d-t fusion reactors. Radiation damage in Li 2O was investigated in IEA BEATRIX-II phase 1 irradiation tests using the Fast Flux Test Facility (FFTF). Li 2O single crystal specimens with various 6Li concentrations, 6Li/( 6Li + 7Li), were irradiated at about 650 K for 300 effective full power days in FFTF by fast neutrons (the fast neutron fluence) ( > 0.1 MeV): 3.9 × 10 26 n/m 2). After the neutron-irradiation, measurements of electron-spin resonance (ESR) and optical absorption were carried out for the specimens at room temperature. From the measurements, colloidal lithium metal was found to be formed in Li 2O irradiated with fast neutrons.
