We determined the effects of fast-neutron damage aione on four types of pyrolytic-carbon coatings with spherical geometry. The coatings, which ranged in density from 1.75 to 2.0'7 g/cm" and had Bacon anisotropy factors from 1-O to 1.4, were irradiated in the Dounreay Fast Reactor to 4.5 X 102" neutr

The density and dimensional changes induced by fast-neutron irradiation of isotropic pyrolytic carbons deposited below 1500ยฐC have been investigated. Irradiation temperatures ranged from 600" to 1400ยฐC and fast-neutron fluences extended to 8 X 10" n/cm2. It has been found that, in contrast to the mo

Measurement have been made of the dimensional changes induced by fast neutrons in natural graphite, annealed pyrolytic carbon, catalytically graphitised carbon, and turbostratic carbon, for irradiation temperatures below 1300ยฐC.
