The changes in dimensions and lattice parameters produced by irradiation in two reactors with very different dose rate have been studied over the temperature range 400-700ยฐC. In this range it is found that the activation energy associated with the equivalent temperature concept is not constant. It i

The energy H stored by graphite under the effect of neutron radiation can be released by thermal annealing. It is possible to determine by differential thermal analysis the differential enthalpy dH/dO (cal/g/'C) as a function of the annealing temperature 8. Integration of the spectrum obtained gives
The linear dimensional changes of anisotropic and near-isotropic graphites were measured after irradiation in the range 300 to 1500ยฐC to 3.3 x 102r n/cm" (E > 0.18 MeV). The presence of a nongraphitizing impregnant coke in an anisotropic needle-coke graphite increased its volume contraction, reduced
