The annealing of pyrolytic carbon following neutron irradiation at liquid nitrogen temperature is described by means of two series of considerations. The first one concerns the definition of suitable intervals of temperature identifying each individual process, as well as the relative limits of this picture regarding the influence of the structure of the samples andor the dose received. The second one concerns the description of the mechanism, the nature of point-defects and the related activation energies governing the recovery in any single stage.
