Oxidation rates of alternately irradiated and annealed graphite

摘要: Abstract Oxidation rates and activation energies between 350° C 500° were obtained for pile grade graphite after seventeen cycles of neutron reirradiations anneals. Although considerable radiation damage was retained this treatment, neither the oxidation nor energy could be distinguished from unirradiated control stock. The defects responsible enhancement in first irradiation appear to removed when is subjected alternate low temperature It assumed that only vacancy species both continuously irradiated cycled graphites monovacancy. therefore concluded specific interstitial clusters cause observed irradiation.
